     DESCRIPTION OF EMBODIMENTS 
     The technical solution in the embodiments of the present disclosure will be described clearly and fully below in conjunction with the drawings in the embodiments of the present disclosure. 
       FIG. 1  is an example of an applicable network scenario of an embodiment of the present disclosure. 
     The network scenario of  FIG. 1  may include at least one terminal device  101   a ,  101   b ,  101   c , etc. (in the text below, if no distinction of these terminal devices is required, the terminal devices may be collectively referred to as terminal device  101 ). An example of  FIG. 1  depicts a scenario of three terminal devices, however, the present disclosure does not make a limitation to the number of the applicable terminal device  101 . 
     The present disclosure does not make a limitation to the type of the terminal device  101  either. For example, the terminal device  101  may be a mobile terminal, such as a cell phone, a tablet device, a wearable device, and the like; the terminal device  101  may also be a computer, such as a notebook computer and the like; and the terminal device  101  may also be an electronic device for other uses, such as a digital camera, a scanner, an electronic book, and the like. 
     A cloud server end  104  is configured to provide a cloud service to a user, such as cloud storage, cloud computing, cloud exchange, etc. The cloud service is generally provided for users so that the same user may use the same cloud service on different devices. For example, one user may use a digital camera to capture a picture, a cloud server end receives and stores the picture from the digital camera, and then the user may view the captured picture on other devices (such as a cell phone) via a cloud service, or may edit the captured picture on other devices (such as a computer) via the cloud service. 
     It should be noted that “a user” in the present disclosure not only includes a case of an individual user, but also that of the same user used by a number of people, for example, all members of one family may use a cloud service corresponding to the same user. 
     In a case where a number of people use the same user, these people may use the same user name/password, and may also use different user names/passwords. As one schematic example for using the same user name/password, with regard to a cloud sharing service for pictures for example, a number of people may all use a user name user 1, and a password pw1. As one schematic example for using different user names/passwords, with regard to a cloud service for a group chat of a user groupi (representing the i-th group chat) for example, each participant of the group chat may use his or her own user name groupi_userj (representing the j-th participant in the i-th group chat) and a corresponding password pwj. The format of the user name/password in the example given above is merely exemplary, and does not constitute a limitation to the scope of the present disclosure. 
     A wireless communication network  103  may include various available wireless communication protocol networks. For example, the wireless communication network  103  may include a mobile communication network, such as a GSM network, a CDMA network, a WCDMA network, an LTE network, an LTE-A network or other mobile communication networks. In the mobile communication network, an access and routing function is generally provided to a wireless communication device  102  via a base station (such as a BS, a NodeB, an eNodeB, etc.). 
     For another example, the wireless communication network  103  may include a wireless local area network (WLAN), such as a network in support of a WiFi protocol or other types of wireless local area networks. In the wireless local area network, an access and routing function is generally provided to the wireless communication device  102  via an access point (such as an AP, etc.). 
     Furthermore, the wireless communication network  103  may further include other types of communication devices required for providing a cloud service, for example, may include communication devices via a wired connection, such as a core network, a wide area network, and other parts. As another embodiment, the wireless communication network  103  may further support a hybrid network comprising a mobile communication network and a wireless local area network, for example, the wireless communication device  102  may access the mobile communication network and the wireless local area network simultaneously, where the two networks provide an offloading function with each other to improve system throughput. A control plane of the wireless communication device  102  may be disposed on one of the two networks, or the wireless communication device  102  may be coordinately controlled by the two networks. 
     The network scenario of  FIG. 1  may further include the wireless communication device  102  according to an embodiment of the present disclosure. The wireless communication device  102  is mainly used for supporting a uniform access and verification of each of the terminal devices  101  for one user. Therefore, the wireless communication device  102  may be referred to as “a cloud hotspot” or “a cloud hotspot device”. Such a cloud hotspot is responsible for completing all control plane functions (such as an access and verification, etc.) related to a cloud service between a user and a cloud end. After completing a verification (a cloud service verification) with the cloud server end, the cloud hotspot may maintain a connection with the cloud server end to the greatest extent (e.g., through a heartbeat mechanism, a standby mechanism, a keep-alive mechanism or other similar mechanisms), so as to provide a cloud service for a newly connected terminal at any time. Such a cloud hotspot may be regarded as an extension channel entrance for the cloud server end to follow user&#39;s movement. Of course, after completing the cloud service verification, the cloud hotspot may also keep silent and be activated as required, and may maintain a context of the cloud hotspot at the cloud server end all the time (or during a significant period of time) so that the cloud hotspot may recover a channel function as soon as possible when there is a need to provide a cloud service to a terminal of a user. Generally speaking, user plane data related to a cloud service between a terminal of the user and a cloud end may also be relayed and transferred via a cloud hotspot. 
     Specifically, one user may own one or more terminal devices  101 . When these terminal devices  101  are using the cloud service, the wireless communication device  102  is responsible for access and verification tasks of both the wireless communication network  103  and the cloud server end  104 , while the terminal devices  101  only need a short-range wireless connection capability to be easily connected with the wireless communication device  102 . Optionally, in order to enable the terminal devices  101  of the user to use the cloud service more conveniently and quickly, the cloud hotspot may not perform a connection verification on the terminal devices  101 , for example, when the cloud hotspot uses a Bluetooth function, the Bluetooth function may be set to be in open connection with any neighboring terminal device without input of a matching character string by the terminal device. Of course, for the sake of security, the cloud hotspot may also perform the connection verification on the terminal devices  101 . Alternatively, the connection verification may be set not to be performed merely on a secure terminal device  101  (e.g., the terminal device  101  has been previously connected), but to be performed on other terminal devices  101 . 
     According to the embodiment of the present disclosure, the terminal devices  101  may not need a complex hardware and software design for a communication network and a cloud service, but only a short-range wireless connection with the wireless communication device  102 . For example, the terminal devices  101  may only support a WiFi connection function, and the wireless communication device  102  completes a cloud service verification and a wireless communication network verification of a user, so that the terminal devices  101  may use a cloud service for the user provided by the cloud server end  104  directly after establishing a WiFi connection with the wireless communication device  102  of a certain user. 
     It should be noted that in the embodiment of the present disclosure, “a short-range wireless connection” refers to a short-range communication mode in the order of a hundred meters or shorter in distance, for example, a range covering several meters or tens of meters, or even a range as short as several centimeters or a near field, rather than a connection mode of a mobile communication network in the order of several hundreds of meters and even several kilometers. Typical examples of the short-range wireless connection are WiFi, Bluetooth, infrared, and visible light connection (such as an indoor light), near-field electromagnetic induction, etc., but exclude a wireless communication system utilizing a base station, such as 2G, 3G, 4G or 5G, etc. Specifically, two sides in a short-range wireless connection establish a connection without a third party device such as a base station (neither a control plane nor a data plane needs intervention of a base station), but connect therebetween directly based on a corresponding communication protocol. 
     In the embodiment of the present disclosure, the wireless communication device  102  performs an identity verification on a user, for example, adopting a biological information verification (such as a fingerprint, an iris, voice, facial identification, vascular patterns, etc., or any combination of these modes), an input verification (e.g., a user may input a user name/password thereof through an input device such as a button, a keyboard, a mouse, a microphone, etc.), a hardware device verification (such as a subscriber card, an NFC card, a key, etc.), or any combination of each of the above verification modes. 
     Access and verification processing for a certain user to access a wireless communication network (e.g., through verification such as a SIM, a UIM, a MAC address, an IP address, etc.) or login verification processing for logging in a cloud server end (e.g. inputting a user name/password of a cloud service, etc.) may be performed separately before or after the wireless communication device  102  performs an identity verification of the user. Alternatively, according to setting of the network/the cloud server end, the above access verification or the login verification is performed by incorporating the identity verification of the user, for example, the wireless communication device  102  may be customized for a certain cloud service, and a correspondence among the wireless communication device  102 , a corresponding cloud service and corresponding user identity information is established in the cloud server end  104 ; and when the wireless communication device  102  verifies the user identity successfully, the wireless communication device  102  logs in the cloud service directly without cloud service login verification. The incorporated verification mode may be similarly applied to access verification of the wireless communication network  103 . 
     As such, in the embodiment of the present disclosure, a hardware/software design requirement for the terminal devices  101  is lower, and the terminal devices  101  only need a short-range wireless connection capability to be easily connected with the wireless communication device  102 , so that costs of a production provider of the terminal devices  101  may be reduced significantly, for example, addition of a WiFi module or a Bluetooth module simply on the basis of an existing electronic device without communication capability is merely needed. Meanwhile, the technical solution of the present disclosure does not give away use security simultaneously with providing use convenience, and an identity verification needs to be performed on a user when a cloud hotspot is used, in other words, the cloud hotspot is customized for the user, even though the cloud hotspot is lost or stolen, other users cannot pass the identity verification either, and therefore, cannot use the cloud hotspot to obtain a cloud service and relevant data of the cloud service. Further, the cloud hotspot of the present disclosure may provide a security processing capability such as positioning, locking and the like, for example, when the number of failure times of user verification reaches a predetermined number of times, the cloud hotspot can be locked to be incapable of further use; alternatively or additionally, the cloud hotspot may send its location to the cloud server end or other network side devices so that an actual user of the cloud hotspot retrieves the cloud hotspot in time. 
     In the embodiment of the present disclosure, since access to the terminal device  101  no longer needs a complex login verification process, user experience is better and convenience is higher. 
     In addition, a cloud hotspot of the embodiment of the present disclosure is bound with a corresponding cloud service, an identity verification performed by the cloud hotspot is also an identity verification required by the corresponding cloud service, whereas a traditional hotspot device (such as a WiFi hotspot) merely provides a communication channel, but is unrelated with a cloud service. The traditional WiFi hotspot merely performs user verification on a user for security of a network operator regardless of requirements of the cloud service, and therefore, cannot be bound with the cloud service and the user, and cannot provide a user personalized service based on the cloud service. 
     Moreover, an operation for use of a cloud service via a traditional WiFi hotspot is relatively complex, a specific app, a client end proxy or a browser are generally required to be mounted on a terminal so as to be connected with a cloud server end through such app, client end proxy or browser, and this requires software support of the terminal, for example, software support of an application layer and even an operating system layer, especially for some conventional terminals, such as a television, a camera and the like; and such software needs to be specifically developed, costs are higher and use is inconvenient, subsequent software update is also troublesome, and not beneficial to continuous upgrading and reconstruction of an entire cloud service. However, a cloud hotspot of the embodiment of the present disclosure does not require complex software support of a terminal. When a cloud service is upgraded, the cloud hotspot of the present disclosure only requires to upgrade software of the cloud hotspot without upgrading software of each terminal like a traditional WiFi hotspot solution. A function of a future cloud service necessarily requires to upgrade and promote performance continuously so as to bring more values to a user. A cloud hotspot of the present disclosure is more suitable to this application environment. 
       FIG. 2  is a schematic block diagram of a wireless communication device of an embodiment of the present disclosure. A wireless communication device  20  of  FIG. 2  is a specific example of the wireless communication device  102  of  FIG. 1 . 
     As shown in  FIG. 2 , the wireless communication device  20  includes a verifying module  21 , a first accessing module  22 , a second accessing module  23  and a transmitting module  24 . 
     The verifying module  21  is configured to perform an identity verification on a user of the wireless communication device  20 . For example, the verifying module  21  may adopt a biological information verification (such as a fingerprint, an iris, voice, facial identification, vascular patterns, etc., or any combination of these modes), an input verification (e.g. a user may input a user name/password of the user through an input device such as a button, a keyboard, a mouse, a microphone, etc.) and a hardware device verification (such as a subscriber card, an NFC card, a key, etc.), or any combination of each of the above verification modes. 
     The first accessing module  22  is configured to establish, when the verifying module  21  verifies the user successfully, a cloud service connection with a cloud server end (e.g., the cloud server end  104  shown in  FIG. 1 ) of the user via a wireless communication network (such as the wireless communication network  103  shown in  FIG. 1 ). 
     The second accessing module  23  is configured to establish a short-range wireless connection with one or more external terminal device(s) (e.g., the terminal devices  101  shown in  FIG. 1 ). Examples of the short-range wireless connection may include a WIFI connection, a Bluetooth connection, an infrared connection, a visible light connection, etc. The visible light connection may adopt, for example, a spectrum of a lamplight to connect, and perform communication using fast on-off of a visible light (generally, at a speed imperceptible to human eyes). 
     The transmitting module  24  is configured to relay data between the external terminal device and the cloud server end via the short-range wireless connection and the cloud service connection. 
     As such, in the embodiment of the present disclosure, one wireless communication device provides a uniform access and verification processing of a cloud service for one user, so that lower design requirement is required from various terminal devices of the user, and design and production costs of the terminal devices can be reduced. 
     Furthermore, the uniform access and verification processing of a cloud service for one user provided by one wireless communication device, interconnection between each of terminal devices of the user can be realized better, for example, a picture captured by a digital camera of the user may perform instant presentation on a cell phone of the user conveniently, thereby enhancing user experience significantly. 
     Optionally, as another embodiment, the verifying module  21  may further perform an access verification with the wireless communication network (e.g., the wireless communication network  103  shown in  FIG. 1 ). For example, the wireless communication device  20  may be provided with a slot for inserting a SIM card or a similar subscriber identity card, or the wireless communication device  20  may be internally installed with a SIM card (i.e., an embedded SIM card) or a similar subscriber identity card, and such a subscriber identity card is configured to perform access verification when the wireless communication network is accessed. 
     As another embodiment, an access verification processing of a wireless communication network may also be implemented by a cloud server end entirely (in this case, the cloud server end may be regarded as an access verification proxy of a wireless communication device) so as to exempt use of a subscriber identity card such as a SIM card, and save space of the wireless communication device  20  so that the volume of the wireless communication device  20  is more compact. In the other aspect, since messaging for an access verification processing between the wireless communication device  20  and the wireless communication network is not required, electric power of the wireless communication device  20  can also be saved. This is an actual NO-SIM-CARD solution. Currently, there exists solutions such as a virtual SIM card or an e-SIM card, however, these solutions do not exempt a SIM card completely, but merely convert the SIM card into a built-in or embedded chip. 
     Specifically, as one example, a correspondence between a device identifier (such as an IMEI or a similar identifier) and a predetermined user identifier (such as an IMSI or a similar identifier) of the wireless communication device  20  is bound at a cloud server end or an operator end in advance; access verification may be performed on the cloud server end after an identity verification is performed on the user (e.g., during establishment of the above cloud service connection) or independent of the identity verification (e.g., during initial activation of the wireless communication device  20 ); in other words, the present disclosure does not make a limitation to the time for such access verification. For example, in a case where an operator end stores correspondences between device identifiers and user identifiers, a cloud server end may send the device identifier of the wireless communication device  20  to a server of the operator end, and the operator end looks up the corresponding user identifier according to the device identifier of the wireless communication device  20 , and performs an authentication and activation operation on the basis of the user identifier (e.g., exchanging authentication information with the cloud server end, and optionally, allocating a TMSI for the user identifier, and other operations), so that the wireless communication device  20  may perform communication with a wide area network using a wireless communication network. For another example, in a case where a cloud server end stores correspondences between device identifiers and user identifiers, the cloud server end may send the device identifier and the corresponding user identifier of the wireless communication device  20  to a server of an operator end, and the operator end performs an authentication and activation operation on the basis of the user identifier (e.g., exchanging authentication information with the cloud server end, and optionally, allocating a TMSI for the user identifier, and other operations), so that the wireless communication device  20  may perform communication with a wide area network using a wireless communication network. 
     As another example, a cloud server end may generate a user identifier according to a device identifier, for example, conversion between a device identifier and a user identifier may follow a specific algorithm, and the cloud server end converts the device identifier according to such algorithm to obtain a corresponding user identifier. 
     As yet another example, an operator end may allocate a user identifier for the wireless communication device  20  as required. Specifically, for example, a cloud server end may send a device identifier of the wireless communication device  20  to a server of the operator end, the operator end allocates a corresponding user identifier for the device identifier of the wireless communication device  20 , and performs an authentication and activation operation on the basis of the user identifier (e.g., exchanging authentication information with the cloud server end, and optionally, allocating a TMSI for the user identifier, and other operations), so that the wireless communication device  20  may perform communication with a wide area network using a wireless communication network. 
     As another simpler solution, a device identifier and a user identifier of a wireless communication device may be united to be one identifier. For example, a user identifier IMSI may be directly used as a device identifier of a wireless communication device, and vice versa. 
     In the above NO SIM CARD solution, for security of authentication, authentication information corresponding to a user identifier (such as an IMSI) is stored in both a cloud server end and an operator end (such as an authentication server), for example, a Ki secret key, an algorithm version, and the like for use in the authentication process; in addition, information interaction between the cloud server end and the operator end may be encrypted so as to further enhance security of authentication. The specific authentication algorithm may refer to an existing algorithm. 
     After the operator end allocates a TMSI, the operator end may send the allocated TMSI to the cloud server end; and for subsequent cloud service data messaging, the cloud server end may send the TMSI to the wireless communication device  20 . Alternatively, the operator end may send the allocated TMSI to the cloud server end directly. 
     Optionally, as another embodiment, the verifying module  21  may further perform a login verification with a cloud server end. For example, the wireless communication device  20  may be provided with an input device or externally connected with an input device for inputting login verification information of the cloud server end, for example, a user name/password. As yet another embodiment, login verification of the cloud server end may be incorporated with the above identity verification, for example, a user fingerprint may be acquired, and the fingerprint information may be used for the identity verification and the login verification of the cloud server end simultaneously; at this time, correspondences between users and fingerprint information thereof may be recorded at the cloud server end. 
     Optionally, as still another embodiment, a wireless communication network (e.g., the wireless communication network  103  shown in  FIG. 1 ) may include a mobile communication network and/or a wireless local area network. For example, the wireless communication network may be a cellular network provided by a wireless operator, including an access network element, a core network element and other devices, and connected with a server of a cloud server end or the server of the cloud server end via a wide area network. The wireless local area network may be a WiFi network that is connected with a wide area network through devices such as a router and a switch, and further to a server of a cloud server end. 
     Furthermore, in the embodiment of the present disclosure, a server of a cloud server end (e.g., the cloud server end  104  shown in  FIG. 1 ) may be centralized or may also be distributed, and the present disclosure does not make a limitation to it. 
     Optionally, as one embodiment, the verifying module  21  may lock the wireless communication device to be incapable of further use, and/or send a location of the wireless communication device to the cloud server end or other network side devices through the transmitting module  24 , when the number of failure times of the identity verification reaches a predetermined number of times. This can enhance security of a cloud service for a user, prevent leakage of user information after a cloud hotspot is lost or stolen, and may help the user retrieve the cloud hotspot according to location information, and reduce user loss. 
     A cloud service may provide various types of services, such as a picture stream, a video stream or a character stream and the like. For different data streams, there may be characteristic processing instructions respectively in order to provide diversified services for a user. 
     Some embodiments of the present disclosure are described in details below in conjunction with specific examples. It should be noted that examples below are just for helping those skilled in the art to better understand concepts of the present disclosure, instead of limiting the scope of the present disclosure. 
       FIG. 3  is a schematic interaction diagram of one applicable scenario example of the present disclosure.  FIG. 3  is an exemplary scenario in which a cloud service provides a picture stream. In an embodiment of  FIG. 3 , a user carries a portable wireless communication device  33 , and a camera  31  and a cell phone  32  of the user establish short-range wireless connections with the wireless communication device  33  respectively so that a cloud service of the user can be used. The wireless communication device  33  may be the wireless communication device  102  of  FIG. 1  or the wireless communication device  20  of  FIG. 2 . In addition, the user has achieved purchase of a cloud service of a cloud server end  34 , and user information of the user is recorded at the cloud server end  34 , for example, a user name, permission, etc. In the embodiment of  FIG. 3 , a cloud sharing service is used as a non-limiting specific example for a cloud service. 
       301 , the wireless communication device  33  performs an identity verification on a user, such as a biological information verification, an input verification and a hardware device verification, etc. 
       302 , when the identity verification is successful, the wireless communication device  33  establishes a cloud service connection with the cloud server end  34  of the user via a wireless communication network. Optionally, the cloud server end  34  may perform a login verification with a user once again during establishment of a cloud service connection. 
     Optionally, when identity verification fails or the number of failure times of the identity verification reaches a predetermined number of times (e.g., three times, five times, etc.), the wireless communication device  33  may be locked to be incapable of further use, for example, it may be locked for a period of time before the identity verification is performed once again; and when the identity verification performed once again fails or the number of failure times reaches a predetermined number of times again, it may be locked for longer time before the following identity verification is performed. In addition, optionally, when the accumulated number of times of identity verification during a predetermined time period (e.g., within a day or a week) reaches a greater numerical value (e.g., 10 times or 20 times), it is deemed that there is a great possibility that the wireless communication device  33  has been lost or stolen, and the wireless communication device  33  may send its current location to a predetermined device (e.g., the cloud server end  34  or other network side devices, such as a network side device providing security), so that a user of the wireless communication device  33  can acquire the current location of the wireless communication device  33  so as to facilitate retrieval of the wireless communication device  33 . Sending of the current location may be periodic, and may also be triggered based on an event, for example, at the time when the accumulated number of times of identity verification reaches a greater numerical value, or the wireless communication device  33  receives a device retrieval command issued by a user through other means (e.g., issuing the device retrieval command through the cloud server end  34 ), the wireless communication device  33  is triggered to send the current location. This can enhance security of a cloud service. 
       303 , the cloud server end  34  may record information of the wireless communication device  33 , indicating that the wireless communication device  33  is being used by the user, so that a cloud sharing service provided by the cloud server end  34  can be used. 
     In this case, if a wireless communication device is temporarily disconnected from a wireless communication network or a cloud server end due to certain reasons (e.g., a signal quality is bad or a user logs out actively), the cloud server end may temporarily retain information about the wireless communication device recorded in step  303  within a certain time limit (such as within half an hour or ten minutes), so that the temporarily retained information can be used when the wireless communication device attempts to establish a connection with the cloud server end once again, thereby speeding up the process of attempting to establish a cloud service connection once again. Of course, the cloud server end may also release the recorded information about the wireless communication device when discovering the wireless communication device is disconnected so as to save storage space. 
       304 , the camera  31  of the user establishes a short-range wireless connection with the wireless communication device  33 . For example, the camera  31  may have a Bluetooth function module for establishing a Bluetooth connection with the wireless communication device  33 . The present disclosure does not make a limitation to a protocol type and mode in which the camera  31  establishes the short-range wireless connection with the wireless communication device  33 . 
       305 , the wireless communication device  33  sends device information of the camera  31  to the cloud server end  34 , and the cloud server end  34  records the device information of the camera  31 . The device information may include but is not limited to a device identifier, device capability information (such as capturing a picture) and/or other parameter information (such as a format, a size of the picture, etc.) of the camera  31 . 
       306 , the cell phone  32  of the user establishes a short-range wireless connection with the wireless communication device  33 . For example, the cell phone  32  may have a Bluetooth function module for establishing a Bluetooth connection with the wireless communication device  33 . The present disclosure does not make a limitation to a protocol type and mode in which the cell phone  32  establishes the short-range wireless connection with the wireless communication device  33 . 
       307 , the wireless communication device  33  sends device information of the cell phone  32  to the cloud server end  34 , and the cloud server end  34  records the device information of the cell phone  32 . The device information may include but is not limited to a device identifier, device capability information (such as displaying a picture) and/or other parameter information (such as a format, a size of the picture, etc.) of the cell phone  32 . 
       308 , the user uses the camera  31  to capture a picture. 
       309 , the camera  31  sends the captured picture to the cloud server end  34  through the wireless communication device  33 . The process may be referred to as a picture synchronization processing. The camera  31  may perform picture synchronization simultaneously with capturing the picture, and may also perform picture synchronization according to an operation of the user (e.g., the user may input an instruction to indicate the camera  31  to perform a picture synchronization processing). 
     Optionally, the camera  31  may mark up the picture indicating which of pictures have been uploaded to the cloud server end, while which of pictures have not been uploaded. 
       310 , the cloud server end  34  stores the picture uploaded by the camera  31 . In addition, the cloud server end  34  may record relevant information of the picture, for example, source (i.e., the camera  31 ), capturing time, capturing place, etc. 
       311 , the cloud server end  34  pushes the picture to the cell phone  32  through the wireless communication device  33 . 
     For example, the cloud server end  34  discovers that the cell phone  32  also subscribes a cloud sharing service according to the device information of the cell phone  32 , and therefore, sends the picture captured by the camera  31  to the cell phone  32 . If the cell phone  32  has a specific requirement for a format or size of a picture, the cloud server end  34  may perform a format conversion processing on the picture uploaded by the camera  31  according to the specific requirement so as to satisfy the requirement of the cell phone  32 . As one optional embodiment, especially in a case where a terminal device uploading data (i.e., a synchronization source of data) and a target terminal device to push the data (i.e., a synchronization destination of the data) do not use the wireless communication device  33  simultaneously, the format conversion processing is preferentially performed by the cloud server end  34 . 
     As another embodiment, format conversion processing of a picture may also be performed by the wireless communication device  33 , and even the cell phone  32 . For example, when the wireless communication device  33  performs the above format conversion processing, the device information of the cell phone  32  may also be recorded on the wireless communication device  33  in advance. When sending the picture to the wireless communication device  33  via the cloud service connection, the cloud server end  34  may designate the destination of the picture as the cell phone  32 ; when receiving the picture, the wireless communication device  33  may perform a format conversion processing on the picture according to a format or size requirement locally stored in the device information of the cell phone  32  so as to satisfy the requirement of the cell phone  32 , and send a converted picture to the cell phone  32  via a short-range wireless connection. In an optional embodiment, in a case where a synchronization source and a synchronization destination of data use the wireless communication device  33  simultaneously, the format conversion processing is preferentially performed by the wireless communication device  33 . 
     In addition, the cloud server end  34  may perform a mark-up processing on a picture stored on the cloud server end  34  indicating whether the picture has been pushed to the cell phone  32 . 
     As such, according to the present embodiment, use of a cloud service by a user terminal device can be achieved through a wireless communication device, and the user terminal device only needs a short-range wireless connection capability to be easily connected with the wireless communication device. 
     In the embodiment of  FIG. 3 , the terminal devices  31  and  32  of a user are not transparent to the cloud server end  34 , that is, the cloud server end  34  may record identification information, connection state and the like of the terminal devices  31  and  32  of the user. However, the present disclosure is not limited to this, a cloud server end may not record or know the condition of a terminal device of a user either, and all operations of the cloud server end aim at a wireless communication device. 
     It should be noted that sequence numbers of steps in  FIG. 3  do not constitute a limitation to execution sequence of the each step. For example, steps  306 - 307  are not necessarily executed ahead of steps  308 - 310 . A similar scenario may be that a camera captures a picture, and then uploads the picture to a cloud server end for storage through a cloud hotspot; and a cell phone may be connected with the cloud server end through the cloud hotspot only after capturing, in this case, after a specific period of time, or when the cloud server end discovers that a new picture has not been pushed to the cell phone, the cloud server end may push the picture to the cell phone through the cloud hotspot. 
       FIG. 4  is a schematic interaction diagram of another applicable scenario example of the present disclosure.  FIG. 4  is an exemplary scenario in which a cloud service provides a video stream. In an embodiment of  FIG. 4 , a user carries a portable wireless communication device  43 , and a display terminal  41  and a display terminal  42  of the user may be located at different places, and may establish short-range wireless connections with the wireless communication device  43 , respectively. 
     In the embodiment of  FIG. 4 , a cloud video playing service is used as a non-limiting specific example for a cloud service. 
       401 , the wireless communication device  43  performs an identity verification on a user, for example, a biological information verification, an input verification and a hardware device verification, etc. 
       402 , when the identity verification is successful, the wireless communication device  43  establishes a cloud service connection with the cloud server end  44  of the user via a wireless communication network. Optionally, the cloud server end  44  may perform a login verification with a user once again during establishment of a cloud service connection. 
     Optionally, when identity verification fails or the number of failure times of the identity verification reaches a predetermined number of times (e.g., three times, five times, etc.), the wireless communication device  43  may be locked to be incapable of further use, for example, it may be locked for a period of time before the identity verification is performed once again; and when the identity verification performed once again fails or the number of failure times reaches a predetermined number of times again, it may be locked for longer time before the following identity verification is performed. In addition, optionally, when the accumulated number of times of identity verification during a predetermined time period (e.g., within a day or a week) reaches a greater numerical value (e.g., 10 times or 20 times), it is deemed that there is a great possibility that the wireless communication device  43  has been lost or stolen, and the wireless communication device  43  may send its current location to a predetermined device (e.g., the cloud server end  44  or other network side devices, such as a network side device providing security), so that a user of the wireless communication device  43  can acquire the current location of the wireless communication device  43  so as to facilitate retrieval of the wireless communication device  43 . Sending of the current location may be periodic, and may also be triggered based on an event, for example, at the time when the accumulated number of times of identity verification reaches a greater numerical value, or the wireless communication device  43  receives a device retrieval command issued by a user through other means (e.g., issuing the device retrieval command through the cloud server end  44 ), the wireless communication device  43  is triggered to send the current location. This can enhance security of a cloud service. 
       403 , the cloud server end  44  may record information of the wireless communication device  43 , indicating that the wireless communication device  43  is being used by the user, so that a cloud video playing service provided by the cloud server end  44  can be used. 
       404 , the display terminal  41  of the user establishes a short-range wireless connection with the wireless communication device  43 . For example, the display terminal  41  may have a Bluetooth function module for establishing a Bluetooth connection with the wireless communication device  43 . The present disclosure does not make a limitation to a protocol type and mode in which the display terminal  41  establishes the short-range wireless connection with the wireless communication device  43 . 
     As one non-limiting example, the display terminal  41  may be a tablet computer in the home of a user, and the user uses the tablet computer to use a cloud video playing service provided by the cloud server end  44  through the wireless communication device  43 , for example, watching a certain movie. 
       405 , the user needs to go out to home of a friend, and therefore, inputs a pause instruction on the display terminal  41  (the tablet computer) to suspend the playing of the movie. 
       406 , the display terminal  41  sends the pause instruction of the user to the cloud server end  44  through the wireless communication device  43 . Optionally, the display terminal  41  or the wireless communication device  43  may send breakpoint time information at the pause point together to the cloud server end. 
       407 , the cloud server end  44  suspends pushing of a video stream of the movie, and records the breakpoint time information of the movie at this time after receiving the pause instruction of the user. 
     The breakpoint time information herein may be sent and indicated from the wireless communication device  43 , and determined by the cloud server end  44  on its own as well. 
       408 , the user arrives at the friend&#39;s home, and the display terminal  42  of the friend establishes a short-range wireless connection with the wireless communication device  43 . For example, the display terminal  42  may have a Bluetooth function module for establishing a Bluetooth connection with the wireless communication device  43 . The present disclosure does not make a limitation to a protocol type and mode in which the display terminal  42  establishes the short-range wireless connection with the wireless communication device  43 . 
     As one non-limiting example, the display terminal  42  may be a television in the friend&#39;s home, and the user uses the television to use a cloud video playing service provided by the cloud server end  44  through the wireless communication device  43 , for example, watching a certain movie. 
       409 , the user inputs an instruction to resume playing the movie paused at step  405  on the wireless communication device  43  or the display terminal  42 . 
     The wireless communication device  43  may provide an instruction menu for a user to input a resume playing instruction, or the wireless communication device  43  may send instruction menu information to the display terminal  42  so that the display terminal  42  displays the instruction menu according to the instruction menu information, thereby allowing the user to input the instruction to resume playing on the display terminal  42 . 
       410 , the wireless communication device  43  sends the resume playing instruction to the cloud server end  44 . Optionally, if the user watches multiple movies simultaneously, information about a movie that the user wishes to resume playing (such as movie number, movie title, etc.) may further be sent to the cloud server end  44 . 
       411 , after receiving the resume playing instruction, the cloud server end  44  continues to push the video stream of the movie to the wireless communication device  43  at a breakpoint time indicated by the breakpoint time information recorded at step  407 . 
       412 , the wireless communication device  43  relays the video stream of the movie to the display terminal  42  so that the user can resume watching the movie on the display terminal  42 . 
     As such, according to the present embodiment, use of a cloud service by a user terminal device can be achieved through a wireless communication device, and the user terminal device only needs a short-range wireless connection capability to be easily connected with the wireless communication device. 
       FIG. 5  is a schematic interaction diagram of another applicable scenario example of the present disclosure.  FIG. 5  is an exemplary scenario in which a cloud service provides a character stream. In an embodiment of  FIG. 5 , a user carries a portable wireless communication device  53 , and an editing terminal  51  and an editing terminal  52  of the user may be located at different places, and may establish short-range wireless connections with the wireless communication device  53 , respectively. 
     In the embodiment of  FIG. 5 , a cloud editing service is used as a non-limiting specific example for a cloud service. 
       501 , the wireless communication device  53  performs an identity verification on a user, for example, a biological information verification, an input verification and a hardware device verification, etc. 
       502 , when the identity verification is successful, the wireless communication device  53  establishes a cloud service connection with a cloud server end  54  of the user via a wireless communication network. Optionally, the cloud server end  54  may perform a login verification with a user once again during establishment of a cloud service connection. 
     Optionally, when identity verification fails or the number of failure times of the identity verification reaches a predetermined number of times (e.g., three times, five times, etc.), the wireless communication device  53  may be locked to be incapable of further use, for example, it may be locked for a period of time before the identity verification is performed once again; and when the identity verification performed once again fails or the number of failure times reaches a predetermined number of times again, it may be locked for longer time before the following identity verification is performed. In addition, optionally, when the accumulated number of times of identity verification during a predetermined time period (e.g., within a day or a week) reaches a greater numerical value (e.g., 10 times or 20 times), it is deemed that there is a great possibility that the wireless communication device  53  has been lost or stolen, and the wireless communication device  53  may send its current location to a predetermined device (e.g., the cloud server end  54  or other network side devices, such as a network side device providing security), so that a user of the wireless communication device  53  can acquire the current location of the wireless communication device  53  so as to facilitate retrieval of the wireless communication device  53 . Sending of the current location may be periodic, and may also be triggered based on an event, for example, at the time when the accumulated number of times of identity verification reaches a greater numerical value, or the wireless communication device  53  receives a device retrieval command issued by a user through other means (e.g., issuing the device retrieval command through the cloud server end  54 ), the wireless communication device  53  is triggered to send the current location. This can enhance security of a cloud service. 
       503 , the cloud server end  54  may record information of the wireless communication device  53 , indicating that the wireless communication device  53  is being used by the user, so that a cloud editing service provided by the cloud server end  54  can be used. 
       504 , the editing terminal  51  of the user establishes a short-range wireless connection with the wireless communication device  53 . For example, the editing terminal  51  may have a Bluetooth function module for establishing a Bluetooth connection with the wireless communication device  53 . The present disclosure does not make a limitation to a protocol type and mode in which the editing terminal  51  establishes the short-range wireless connection with the wireless communication device  53 . 
     As one non-limiting example, the editing terminal  51  may be a handwriting panel in the home of a user, and the user employs a computing device to use a cloud editing service provided by the cloud server end  54  through the wireless communication device  53 , for example, drawing a certain picture. During editing, the editing terminal  51  may upload some of edited picture documents to the cloud server end  54  periodically or according to a document storage instruction of the user, and the operation may be referred to as a document synchronization operation. 
       505 , the user needs to go out to an office, and therefore, inputs a document storage instruction on the editing terminal  41 , and stores some of edited picture documents to the cloud server end  54 . 
       506 , the editing terminal  51  sends the document storage instruction of the user to the cloud server end  54  through the wireless communication device  53 . Optionally, if updated content of some of picture documents still has not been synchronized to a cloud server end prior to a storage instruction of this document, this part of the updated content may be sent to the cloud server end together. 
       507 , after the cloud server end  54  receives the document storage instruction and the updated content of the user, related picture documents are updated on the cloud server end  54 . 
       508 , when the user arrives at the office, the editing terminal  52  in the office establishes a short-range wireless connection with the wireless communication device  53 . For example, the editing terminal  52  may have a Bluetooth function module for establishing a Bluetooth connection with the wireless communication device  53 . The present disclosure does not make a limitation to a protocol type and mode in which the editing terminal  52  establishes the short-range wireless connection with the wireless communication device  53 . 
     As one non-limiting example, the editing terminal  52  may be a notebook computer in an office, and a user employs the computer to use a cloud editing service provided by the cloud server end  54  through the wireless communication device  53 , for example, drawing a certain picture. 
       509 , the user downloads a picture document which has not been edited at step  505  to the editing terminal  52  through the wireless communication device  53 . 
     The wireless communication device  53  may provide an instruction menu for a user to input a download instruction, or the wireless communication device  53  may send instruction menu information to the editing terminal  52  so that the editing terminal  52  displays the instruction menu according to the instruction menu information, thereby allowing the user to input the download instruction on the editing terminal  52 . As another embodiment, the cloud server end  54  may push the picture document actively to the wireless communication device  53  and further to the editing terminal  52  currently connected with the wireless communication device  53 . 
       510 , the user uses the editing terminal  52  to continue to draw a picture. During editing, the editing terminal  52  may upload some of edited picture documents to the cloud server end  54  periodically or according to a document storage instruction of the user. 
     As such, according to the present embodiment, use of a cloud service by a user terminal device can be achieved through a wireless communication device, and the user terminal device only needs a short-range wireless connection capability to be easily connected with the wireless communication device. 
     Therefore, optionally, as one embodiment, in a wireless communication system of one embodiment of the present disclosure, after identity verification of a user of a wireless communication device is successful, a cloud server end may further record information of the wireless communication device to represent that the wireless communication device is being used by the user. 
     In this case, after the wireless communication device establishes a short-range wireless connection with one or more external terminal device(s), the wireless communication device may further send device information of the external terminal device to the cloud server end, and the cloud server end may record the device information of the external terminal device, for example, device identification, device capability information (such as capturing a picture) and/or other parameter information (such as a format, size of a picture, etc.). 
     Taking a case where external terminal devices include at least two terminal devices such as a first external terminal device and a second external terminal device as an example, a wireless communication device may receive, via a short-range wireless connection with the first external terminal device, data (such as picture data or character data, etc.) acquired by the first external terminal device, and send the data to a cloud server end via a cloud service connection. 
     The cloud server end may perform a format conversion processing on the data according to the device information of the second external terminal device to obtain converted data. The cloud server end may send the converted data to the wireless communication device via a cloud service connection. Then, the wireless communication device may send the converted data to the second external terminal device via the short-range wireless connection with the second external terminal device so that the converted data is displayed on the second external terminal device. 
     The above data format conversion processing may also be performed on a cloud hotspot. In this case, for example, the wireless communication device may receive the above data (without a format conversion processing) of which a destination is the second external terminal device from the cloud server end via the cloud service connection. The wireless communication device may perform a format conversion processing on the data according to the device information of the second external terminal device so as to obtain converted data, and send the converted data to the second external terminal device via the short-range wireless connection with the second external terminal device so that the converted data is displayed on the second external terminal device. 
     Optionally, as another embodiment, the wireless communication device may receive, via a short-range wireless connection with the first external terminal device, first processing instruction information (such as pausing the play, saving a document, modifying a character, etc.) on a current cloud service data stream sent by the first external terminal device, and send the first processing instruction information to the cloud server end via the cloud service connection. The cloud server end processes the current cloud service data stream according to the first processing instruction information. 
     In this case, optionally, the cloud server end may further record status information of the cloud service data stream processed according to the first processing instruction information (such as breakpoint time information about playing, modified document content, etc.). The wireless communication device may receive, via the short-range wireless connection with the second external terminal device, second processing instruction information (such as a resume playing instruction, a new character modification instruction, etc.) on the current cloud service data stream sent by the second external terminal device, and send the second processing instruction information to the cloud server end via the cloud service connection. Then, the cloud server end may process the current cloud service data stream according to the second processing instruction information and the status information. 
     As such, a cloud hotspot of the present disclosure can provide a user with service experience following the user, and provide a uniform cloud service whatever terminal the user uses without being overly limited to hardware or software of the terminal, that is, the cloud hotspot can not only provide a highly qualified cloud service, but also make full use of an existing terminal device of the user without requiring the user to purchase a specially customized terminal, thereby saving social resources significantly, and promoting environment protection and resource reuse. A terminal device having a short-range wireless connection capability (the cost of such a terminal is very low, and easy for promotion) may even be provided in a public place or a private occasion (such as a bus station, a bank, a roadside, a building lobby, a vehicle, etc.). As long as a user carries a cloud hotspot customized with a cloud service, his or her own cloud service can be used on such a terminal device without worrying information security problem, and thus such a cloud service can bring a user great convenience. 
       FIG. 6  is a schematic block diagram of a cloud server end of an embodiment of the present disclosure. 
     A cloud server end  60  of  FIG. 6  is located at a network side and serves as a subscriber identity authentication proxy of a terminal, and the terminal is not configured with a subscriber identity module (such as a SIM card) and cannot be connected with a subscriber identity module (such as having no SIM card slot). The cloud server end  60  includes a receiving unit  61 , an acquiring unit  62  and an authenticating unit  63 . 
     The receiving unit  61  is configured to receive a device identifier of a terminal. 
     The acquiring unit  62  is configured to acquire a subscriber identity of the terminal according to the device identifier of the terminal. 
     The authenticating unit  63  is configured to perform an authentication processing with an authentication server of a mobile communication network based on the user identifier. 
     As such, a cloud server end can serve as a subscriber identity authentication proxy of a terminal. Although the terminal is not configured with the subscriber identity module and cannot be connected with the subscriber identity module, the subscriber identity authentication proxy of the terminal can also be achieved. 
     This can exempt use of a subscriber identity card such as a SIM card, save space of a terminal, and enable volume of the terminal to be more compact. In the other aspect, since messaging for an access verification processing between the terminal and the wireless communication network is not required, electric power of the terminal can also be saved. This is an actual NO SIM CARD solution. Currently, there exists solutions such as a virtual SIM card or an e-SIM card, however, these solutions do not exempt a SIM card completely, but merely convert the SIM card into a built-in or embedded chip. 
     The terminal herein is generally a mobile terminal, but the present disclosure does not make a limitation to a specific implementation form of the terminal, and a terminal in which a plug-in SIM card or an embedded SIM card present in the art may be applied can be improved as a terminal of the present disclosure. 
     As shown in  FIG. 6 , the cloud server end  60  further includes a storing unit  64  configured to store at least one set of correspondences between device identifiers and subscriber identifiers of terminals. The acquiring unit  62  looks up the correspondences according to a device identifier of a terminal so as to acquire a user identifier of the terminal. 
     In this case, the cloud server end may send a device identifier and a corresponding user identifier of the wireless communication device  20  to a server of an operator end, and the operator end performs an authentication and activation operation on the basis of the user identifier (e.g., exchanging authentication information with the cloud server end, and optionally, allocating a TMSI for the user identifier, and other operations), so that the wireless communication device may communicate with a wide area network using a wireless communication network. 
     Optionally, as another embodiment, the storing unit  64  may further store authentication information required for an authentication processing. The authenticating unit  63  may perform the authentication processing based on the authentication information and the above user identifier. 
     Optionally, as another embodiment, the acquiring unit  62  may send a device identifier of a terminal to an authentication server, and receive a user identifier of the terminal from the authentication server, where the authentication server stores at least one set of correspondences between device identifiers and subscriber identifiers of terminals. 
     Optionally, as another embodiment, the acquiring unit  62  may take a device identifier received from the receiving unit  61  as a user identifier of a terminal. 
       FIG. 7  is a flowchart of a communication method of a wireless communication system of an embodiment of the present disclosure. A wireless communication system in which a method of  FIG. 7  may be applied includes a wireless communication device and a cloud server end mutually connected via a wireless communication network, where the cloud server end provides a cloud service for a user of the wireless communication device. An example is a wireless communication system shown in  FIG. 1 . Each process of the method of  FIG. 7  may refer to the corresponding process or function in the previous embodiments of  FIG. 1  to  FIG. 6 , and will not be described in details to avoid repetition. 
       701 , a wireless communication device performs an identity verification on a user of the wireless communication device. 
     For example, the identity verification may be performed with reference to description of the above steps  301 ,  401  and  501 . 
       702 , the wireless communication device establishes a cloud service connection with a cloud server end via a wireless communication network when the user is verified successfully. 
     For example, a cloud service connection may be established with reference to description of the above steps  302 ,  402  and  502 . 
       703 , the wireless communication device establishes a short-range wireless connection with one or more external terminal device(s). 
     For example, a short-range wireless connection may be established with reference to description of the above steps  304 ,  404 / 408  and  504 / 508 . It shall be noted that step  703  may be executed ahead of step  701  or  702 , or simultaneously with step  701  or  702  depending on different specific application scenarios. 
       704 , the wireless communication device relays data of the cloud service between the external terminal device and the cloud server end via the short-range wireless connection and the cloud service connection. 
     For example, cloud service data may be relayed with reference to description of the above steps  309 / 311 ,  406 / 409 - 412  and  506 / 509 . 
     As such, in the embodiment of the present disclosure, one wireless communication device provides a uniform access and verification processing of a cloud service for one user, so that lower design requirement is required from various terminal devices of the user, and design and production costs of the terminal devices can be reduced. 
     Furthermore, the uniform access and verification processing of a cloud service for one user provided by one wireless communication device, interconnection between each of terminal devices of the user can be realized better, for example, a picture captured by a digital camera of the user may perform instant presentation on a cell phone of the user conveniently, thereby enhancing user experience significantly. 
     Optionally, as another embodiment, the wireless communication device or the cloud server end may further perform an access verification with a wireless communication network.
