     DESCRIPTION OF EMBODIMENTS 
       [0029]    The following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. 
         [0030]    An embodiment of the present invention provides a method for acquiring a service.  FIG. 1  is a schematic flowchart of a method for acquiring a service according to an embodiment of the present invention. As shown in  FIG. 1 , the method includes: 
         [0031]      101 . A cloud terminal acquires an identifier of a service card. 
         [0032]    It should be understood that, because of different connection manners between the cloud terminal and the cloud service card and different information transmission manners, the cloud terminal may use multiple methods to acquire the identifier of the service card. 
         [0033]    From the viewpoint as to selection of a wired or wireless connection, the cloud terminal may acquire the identifier of the service card through a wired link or acquire the identifier of the service card through a wireless link. 
         [0034]    From the viewpoint as to whether the cloud terminal and the cloud service card are associated through another device, when the cloud service card is directly connected to the cloud terminal, the cloud terminal may directly acquire identifier information of the cloud service card that is sent by the service card. It may be appreciated that, such a direct acquiring method may be wired or wireless. 
         [0035]    When the cloud terminal and the cloud service card are not directly connected, for example, when the cloud service card is first connected to a cloud input device, and after acquiring the identifier information of the cloud service card, the cloud input device sends the identifier information to the cloud terminal. In this case, the cloud terminal may acquire the identifier information of the cloud service card that is sent by the cloud input device. 
         [0036]    For another example, when the cloud terminal and the cloud service card are not directly connected, after acquiring the identifier information of the cloud service card, the cloud input device may not only send the identifier information of the cloud service card to the cloud terminal but also send other information, for example, a cloud service card connection message, to the cloud terminal and carry the identifier information of the cloud service card in the cloud service card connection message. In this case, the cloud terminal acquires the cloud service card connection message sent by the cloud input device, where the cloud service card connection message includes the identifier information of the cloud service card. 
         [0037]      102 . The cloud terminal acquires a cloud service instruction set corresponding to the identifier of the cloud service card from a cloud instruction set server according to the identifier of the cloud service card. 
         [0038]    After obtaining the identifier information of the cloud service card, the cloud terminal may proactively send the identifier information of the cloud service card to the cloud instruction set server, or the cloud instruction set server acquires the information from the cloud terminal. Its acquiring manner may be implemented by the prior art and is not limited in this embodiment of the present invention. 
         [0039]    The cloud terminal acquires the cloud service instruction set corresponding to the identifier of the cloud service card from the cloud instruction set server according to the obtained identifier of the cloud service card. It should be understood that, the cloud service instruction set acquired by the cloud terminal may be proactively sent by the cloud instruction set server or sent by the cloud instruction set server for responding to a request of the cloud terminal, another request, or other received trigger signals, which is also not limited herein. 
         [0040]    Further, this step may include: 
         [0041]    The cloud terminal sends a request message for acquiring a service instruction set to the cloud instruction set server, where the request message includes the identifier of the cloud service card and an identifier of the cloud terminal. This manner may also be one manner of proactively sending, by the cloud terminal, the identifier information of the cloud service card to the cloud instruction set server. 
         [0042]    The cloud terminal receives the cloud service instruction set sent after the cloud instruction set server performs authentication according to the identifier of the cloud service card and information about the cloud terminal. Because specific authentication is performed by the cloud instruction set server, details are not provided herein. 
         [0043]      103 . The cloud terminal acquires cloud service content from a cloud service server according to a cloud service instruction in the cloud service instruction set. 
         [0044]    It should be understood that, after acquiring the cloud service instruction set delivered by the cloud instruction set server, the cloud terminal acquires the cloud service content from the cloud service server according to a specific cloud service instruction in the received cloud service instruction set. 
         [0045]    In this embodiment, a cloud terminal acquires an identifier of a service card, acquires a cloud service instruction set corresponding to the cloud service card from a cloud instruction set server according to the identifier of the cloud service card, and acquires cloud service content from a cloud service server according to a cloud service instruction in the cloud service instruction set. In this embodiment of the present invention, because the acquired cloud service content is acquired from the service server according to the service instruction, even if the cloud service card does not change, the identifier of the cloud service card does not change, and the cloud terminal does not change, as long as content on the server changes, a user can acquire a changed service. Therefore, this embodiment of the present invention enables the user to conveniently obtain a latest service. 
         [0046]    Another embodiment of the present invention provides a method for acquiring a service.  FIG. 2  is a schematic flowchart of a method for acquiring a service according to another embodiment of the present invention. As shown in  FIG. 2 , the method includes: 
         [0047]      201 . A cloud terminal acquires an identifier of a service card. 
         [0048]    For a specific implementation manner, reference may be made to the previous embodiment. 
         [0049]      202 . The cloud terminal acquires a cloud service instruction set corresponding to the identifier of the cloud service card from a cloud instruction set server according to the identifier of the cloud service card. 
         [0050]    For a specific implementation manner, reference may be made to the previous embodiment. 
         [0051]      203 . The cloud terminal acquires coordinate information of a selected position of the service card. 
         [0052]    When a position on the cloud service card is selected, the cloud terminal acquires coordinate information of the selected position of the service card. 
         [0053]    It should be understood that, because of different connection manners between the cloud terminal and the cloud service card and different information transmission manners, the cloud terminal may use multiple methods to acquire the coordinate information of the selected position of the service card. 
         [0054]    Similar to step  101  in the previous embodiment, in step  203 , the cloud terminal may directly acquire the coordinate information sent by the service card or the cloud terminal may also acquire the coordinate information sent by a cloud input device. It may be appreciated that, the selected position of the cloud service card may be selected by a user through the method of clicking or selected in another manner, which is not limited herein. The position corresponds to a piece of preset coordinate information. When the user clicks a position, a piece of coordinate information corresponds to the position; or when the user clicks in an area, all positions in the area have same coordinate information. 
         [0055]      204 . The cloud terminal acquires a cloud service instruction corresponding to the coordinate information from the cloud service instruction set according to the coordinate information. 
         [0056]    As can be seen from  203 , each position on the service card corresponds to corresponding coordinate information. After acquiring the coordinate information, the cloud terminal may acquire the cloud service instruction corresponding to the coordinate information from the cloud service instruction set obtained in  202  according to the coordinate information. A specific acquiring method may be a method such as search or comparison, which is not limited in this embodiment of the present invention. 
         [0057]    It should be understood that, the cloud service instruction set may include multiple cloud service instructions, and the cloud service instructions may match or correspond to different node areas. In all node areas corresponding to or matching the cloud service instructions in the acquired cloud service instruction set, a node area corresponding to the selected position of the cloud service card is searched according to the coordinate information. 
         [0058]    Specifically, it may be that a node area of each node in nodes of the cloud service instruction set is specified, the coordinate information is compared with node areas to search for a “node area” of a node in which coordinates corresponding to the coordinate information are located, thereby locating a node to which the coordinates belong. In this way, the selected position of the cloud service card is matched with a specific cloud service instruction in the cloud service instruction set, that is, the cloud service instruction corresponding to the coordinate information is acquired from the cloud service instruction set according to the selected position of the cloud service card. 
         [0059]      205 . The cloud terminal acquires cloud service content from a cloud service server according to the cloud service instruction and executes a corresponding operation. 
         [0060]    It should be understood that, a specific cloud service instruction is a specific instruction of a service that the user wants to obtain, and according to the specific instruction, the cloud terminal may acquire the cloud service content from the cloud service server and executes the corresponding operation. 
         [0061]    Further, a specific implementation manner may include the following: 
         [0062]    The cloud terminal acquires node type and node content information included in the service instruction. 
         [0063]    For example, a “node type” refers to a specific service type. For example, it may be specified that the cloud service instruction is for opening a web page, playing a video, executing a program, used as a keyboard or a touch area, or the like. Any type that can be implemented by the prior art may be used as the node type in this embodiment of the present invention, which is not enumerated herein. 
         [0064]    In addition, “node content” may refer to specific service content, for example, specific content that is specified. For example, when the node type is opening a web page, the node content specifies a specific web page to be opened; when the node type is playing a video, the node content specifies a specific video to be played, and so on. 
         [0065]    The cloud terminal acquires the cloud service content from the cloud service server according to the node type and node content information. 
         [0066]    The cloud terminal acquires the cloud service content from the cloud service server according to the obtained node type and node content information and executes the corresponding operation. It should be understood that, here, the executing a corresponding operation may be executing the corresponding operation by the cloud terminal itself or enabling, by the cloud terminal through an interface, an execution device with a corresponding function to execute a specific operation. 
         [0067]    Alternatively, in another specific implementation manner, the cloud terminal acquires node attributes included in the service instruction, and the node attributes further are specifically as follows: 
         [0068]    The node attributes may include a type of an area in which a node is located, an operation area of the node, an operation type of the node, operation content, and the like. The area type is used to indicate that an operation area is a rectangle, a circle, or the like; the operation area indicates a coordinate range of an area; the operation type is a type, such as pressing a key on a keyboard, clicking a mouse, playing a video, and making a telephone call, that indicates how to trigger or show operation content; and the operation content is a true meaning to be triggered through an operation, such as pressing the “A” key on a keyboard. 
         [0069]    When the user clicks in an area of the cloud service card, the cloud input device detects position coordinates of a position clicked by the user and sends the position coordinates to the cloud terminal. According to the received position coordinates, the cloud terminal first searches for an “operation area” of a node in which the position coordinates are located from all nodes of a cloud operation instruction set, thereby locating a node to which the coordinates belong, then, determines, according to an “area type”, that the area is a system area, a user area, or the like, then, determines that an “operation type” is opening a web page, playing a video, executing a program, or the like, and then uses “operation content” as a parameter to invoke a function provided by the cloud terminal to acquire cloud service content specified by the “operation content”. 
         [0070]    The foregoing two manners are only exemplary. Node attributes may be set in a different degree according to needs, multiple attributes may be set to meet multiple requirements, and fewer attributes may be set to meet requirements as simple as possible, which is not limited in the present invention. 
         [0071]    Further, in this embodiment of the present invention, the following may further be included: 
         [0072]    The cloud terminal acquires the cloud service content from the cloud service server according to the cloud service instruction set. 
         [0073]    It should be understood that, it may specifically be that content of a main window corresponding to the identifier of the cloud service card is displayed. 
         [0074]    Further, in this step, the cloud terminal may acquire cloud service content corresponding to the identifier of the service card according to the cloud service instruction set. For example, after acquiring the cloud service instruction set, the cloud terminal parses the cloud service instruction set and acquires and executes the service content according to information such as a type of the cloud service card and content of the cloud service card. 
         [0075]    Specifically, the following may be included: 
         [0076]    The cloud terminal acquires the cloud service card type and the cloud service card content information that are included in the service instruction set. 
         [0077]    It should be understood that, the cloud service instruction set corresponding to the identifier of the service card includes the cloud service card type and the cloud service card content. 
         [0078]    The terminal acquires the cloud service card type and the cloud service card content information specified, and its specific acquiring manner may be implemented by the prior art and is not limited herein. 
         [0079]    The cloud terminal acquires and executes the cloud service content from the cloud service server according to the cloud service card type and the cloud service card content information. 
         [0080]    The cloud terminal acquires the cloud service content from the cloud service server according to the foregoing obtained the cloud service card type and the cloud service card content information specified. A specific obtaining method may be obtaining by the cloud terminal through a request or proactively sending by the cloud service server. The specific method does not affect implementation of the present invention. For example, the type of the cloud service card may include a corresponding operation to be executed by the cloud service card or a type of a service to be provided, and the content of the cloud service card may include content of a corresponding service to be provided by the cloud service card. A specific type and content may be any one in the prior art and are not limited in the present invention. For a specific example, reference may be made to the node type and the node content. Its specific execution manner may be executing the corresponding operation by the cloud terminal itself or enabling, by the cloud terminal through an interface, an execution device with a corresponding function to execute a specific operation. 
         [0081]    Moreover, in the foregoing two embodiments, the cloud service instruction set may be an instruction set that corresponds to the cloud service card and is preset on the cloud instruction set server, and cloud service content may be service content that corresponds to the cloud service card and is preset on the cloud service server. 
         [0082]    In this embodiment of the present invention, a specific cloud service instruction is acquired from a service instruction set by acquiring coordinate information of a selected position of a service card, thereby finally acquiring cloud service content from a cloud service server and executing a corresponding operation, so that a user can obtain a finer service. An operator may provide a service updated in real time for the user through an instruction set that is preset on a cloud instruction set server and service content that is preset on the cloud service server. 
         [0083]    An embodiment of the present invention provides a terminal.  FIG. 3  is a schematic structural diagram of a terminal according to an embodiment of the present invention. As shown in

         [0141]    The identifier in the identifying module of the cloud service card in this embodiment of the present invention enables the cloud terminal to acquire the cloud service instruction set corresponding to the identifier from the cloud instruction set server according to the identifier, so that the cloud terminal can obtain an updated service in a case that the cloud service card does not change. 
         [0142]    Embodiment 8 of the present invention provides a system.  FIG. 10  is a schematic framework diagram of a system according to an embodiment of the present invention. As shown in  FIG. 10 , the system includes a cloud service server  1001 , a cloud instruction set server  1002 , a cloud terminal  1003 , and a cloud service card  1004 . In  FIG. 10 , for easier understanding, a cloud service provider  1007  is further embodied. It should be understood that, the cloud service provider releases cloud service content on the cloud service server, releases a cloud service instruction set on the cloud instruction set server, and can update them in real time according to needs. 
         [0143]    The cloud terminal is configured to acquire an identifier of a service card, acquire a cloud service instruction set corresponding to the identifier of the cloud service card from the cloud instruction set server according to the identifier of the cloud service card, and acquire cloud service content from the cloud service server according to a cloud service instruction in the cloud service instruction set. Specifically, the cloud terminal may be further configured to search for a cloud service instruction corresponding to position coordinates of a selected position on the cloud service card from the cloud service instruction set and send an acquired cloud service instruction to the cloud service server, so as to acquire the cloud service content and perform a corresponding operation. 
         [0144]    The cloud service card includes an identifying module, configured to identify the cloud service card, wherein the identifying enables the cloud terminal to acquire, according to an identifier, the cloud service instruction set corresponding to the identifier from the cloud instruction set server, and an output module, only configured to provide the identifier included in the identifying module. 
         [0145]    The cloud instruction set server is configured to send the cloud service instruction set to the cloud terminal according to the identifier of the cloud service card. 
         [0146]    The cloud service server is configured to provide service content for the cloud terminal according to the cloud service instruction set or the cloud service instruction. 
         [0147]    Further, the system may further include a cloud input device  1005 , configured to: when the cloud input device and the cloud service card are connected, acquire the identifier of the service card, where the cloud input device sends, to the cloud terminal, a message carrying the identifier of the cloud service card, so that the cloud terminal acquires the cloud service instruction set corresponding to the identifier of the cloud service card from the cloud instruction set server according to the identifier of the cloud service card.

The cloud service instruction set is stored on a cloud instruction set server, and a cloud service provider may update the cloud service instruction set and cloud service content at any time. The cloud terminal receives a cloud service card insertion message sent by the cloud input device and acquires a latest cloud service instruction set from the cloud instruction set server or updates an existing cloud service instruction set of the cloud terminal to a latest cloud service instruction set. In this way, when updating an information service, a cloud service operator may enable a user to obtain a latest service with no need of replacing a cloud service card of a customer. 
         [0154]    According to the method, apparatus, and system for acquiring a service that are provided in the embodiments of the present invention, a cloud service provider issues a cloud service card, releases a cloud service instruction set corresponding to the cloud service card on a cloud instruction set server, and releases cloud service content corresponding to the cloud service card on a cloud service server; a cloud terminal determines a specific cloud service instruction according to a position selected by a user on the cloud service card and sends the cloud service instruction to the cloud service server to acquire and display the cloud service content. By using the method provided in the present invention, the user can open resources with one click and quickly obtain desired cloud service content only by selecting a desired service on the cloud service card. Moreover, cost of issuing the cloud service card is low. In addition, it is very convenient to upgrade and update the cloud service instruction set, and the cloud terminal can download a latest cloud service instruction set from the cloud instruction set server in real time, enabling the user to conveniently acquire latest cloud service content in real time.
