Full Description:
FIELD OF THE INVENTION  
       [0001]     The invention relates to the communication technology field, specifically to the wired communication user terminal equipment technology field, and particularly to a user equipment with a wired discontinuous mobile communication function and the method thereof.  
       DESCRIPTION OF THE RELATED ART  
       [0002]     Based on their communication modes, user communication terminal equipments are divided into wireless communication user equipment and wired communication user equipment.  
         [0003]     Present wired communication network technologies like PSTN/ISDN have several advantages, such as friendly communication environments, abundant wired bandwidth resources, high communication quality, more simpler communication and control technology than wireless mobile technologies, security, and reliability. However, compared with wireless mobile communication technologies, the deficiencies of a wired communication network and the wired user terminal equipment, such as fixing, stillness, non-removability, dedication, and non-sharing, severely affect and restrict further and fast development thereof, and make it difficult to adequately utilize the advantages of wired communication technologies in terms of the wired bandwidth resources and so on. Although an emerging IP telephone user terminal equipment based on H.323 and SIP has many advantages as an IP packet technology, its communication relies on an IP address/ domain name which needs to be translated into an IP address. The IP address associatively corresponding to a packet access network device and an access position. As an user equipment changes its access port and position, the packet core network and packet access network device are required to reallocate and configure a new IP address to the user equipment for this change, it is difficult to implement bidirectional communication with numerous traditional PSTN/ISDN and PLMN user equipments. A telephone service for communicating via a unique number is also lacking, as is a telecommunication management and control mechanism, unlike a PSTN or PLMN telecommunication network. Especially problematic is the fact that IP internet network technology based on a non-real time service bearer and a connectionless-oriented service, along with the hybrid transmission and switching of a real time service and a non-real time service, lack the QoS and security assurance of a telecommunication network. Wireless communication, especially wireless mobile communication and the user terminal equipment thereof, have brought agility and convenience to customers in recent years due to the characteristics of such wireless and mobility. The user equipment for wireless mobile communication has advanced from earlier single-function and single-mode user terminal equipments like TACS, AMPS, DAMPS, GSM, IS-95A, and so on, to today&#39;s multi-function and multi-mode user equipments, such as GSM/GPRS, IS95A/B, cdma2000 1x, GSM/cdma2000 1x, and so on. It will continue to advance to future wireless multi-mode, multi-network, multimedia, and multi-function user equipment like 3G WCDMA, cdma2000, TD-SCDMA, Wi-Fi, WiMax, and so on. However, there are inherent, inevitable and unsolvable drawbacks and problems with wireless communication technologies, such as the insufficiency and costliness of wireless frequency resources, low security and privacy, bad communication environments, comparatively poor communication quality, and the requirements for high power radio frequency technologies, along with the increasing complexity of wireless mobile communication and control technologies. These drawbacks and problems with wireless communication technology represent the advantages of wired communication.  
       SUMMARY OF THE INVENTION  
       [0004]     As described above, there is a need for a new network and user terminal equipment technology, namely a discontinuous mobile wired communication technology, which can implement mobile communication in a wired environment to adequately make use of the many advantages of wired communication. On the other hand, wired/wireless communication technologies, networks, and user equipments are converging to enable wireless mobile communication to be flexible and convenient, and to share the advantages of wired communication in some circumstances. It is one object of the invention to provide user equipment with a wired discontinuous mobile communication function.  
         [0005]     Another object of the invention is to provide a method applicable to user equipment with a wired discontinuous mobile communication function, to solve the problems and deficiencies of present wired communication user equipment, such as fixing, stillness, and dedication, and to adequately utilize the many advantages of wired communication.  
         [0006]     The invention provides a novel user equipment with a wired discontinuous mobile communication function. To attain the above objectives, the user equipment of the invention comprises a wired mobile equipment, a universal integrated circuit card, and a terminal equipment. The wired mobile equipment comprises a wired mobile termination and a termination adaptor, and the wired mobile termination comprises a network termination and a wired termination. The universal integrated circuit card comprises a universal subscriber identify module. Based on the architecture defined by ITU-T1.410, the network termination is connected to the wired termination using a T reference point interface, and the wired mobile termination in the wired mobile equipment is connected to the termination adaptor and the universal subscriber identify module in the universal integrated circuit card via the network termination. The wired mobile equipment is connected to the terminal equipment via the termination adaptor by referring to an R reference. The wired user equipment is connected to external user applications, such as computers, via the terminal equipment, and to a wired access network of a wired discontinuous mobile communication network via the wired termination of the wired mobile termination in the wired mobile equipment.  
         [0007]     The user equipment with the wired discontinuous mobile communication function of the invention is a network functional element of the wired discontinuous mobile communication network and a network access device used by a subscriber, which provides communication service application interfaces and services to the subscriber, and has a unique and fixed international mobile equipment identity. The functions of the user equipment comprise: service provision, network login and logoff, access address and location updating, providing a standard interface for plugging in the universal integrated circuit card and the universal subscriber identify module, basic subscriber identification and variable utilization for different subscribers, providing a user interface, supporting an emergency call without subscriber identification, capability of an application programming interface, downloading and storing information, services, functions and protocols, and maintaining a virtual home environment as roaming occurs. The wired mobile equipment in the user equipment is responsible for terminating the functions of all the control planes and wired discontinuous mobile communication network bearer services of a user layer, and the wired mobile termination therein is responsible for terminating communication network system services. The termination adaptor is responsible for adaptation between the wired mobile equipment and the terminal equipment through referring to the R reference point. The terminal equipment in the wired user equipment is a functional device providing subscriber terminal applications. The universal subscriber identify module in the universal integrated circuit card stores subscriber network attributes and subscriber and service information data for the user equipment of the invention, and is responsible for terminating the independent control functions of the user in a local network.  
         [0008]     To attain the above objectives, a user equipment with the wired discontinuous mobile communication function of the invention may change its access address and position in a wired discontinuous mobile communication network, and switch to the coverage area of another wired access network in the wired discontinuous mobile communication network for various communication services and applications via the same wired access technology, without varying its fixed and unique number thereof. Therefore, each functional element in the user equipment of the invention corresponds to, as well as cooperates and interoperates with, that in the wired discontinuous mobile communication network, the wired mobile equipment corresponding to a mobile communication network system, the wired termination therein corresponding to a wired access network, the network termination corresponding to a switching component, a routing component, and a control component in a wired core network, the universal subscriber identify module in the universal integrated circuit card corresponding to a user and user equipment information database in the wired core network, and the terminal equipment corresponding to a terminal equipment in an external communication network. There are two implementations of the user equipment of the invention, one is a wired single-mode user equipment with a wired discontinuous mobile communication function only, and the other is a wireless/wired multi-mode and multi-network user equipment converging a wireless mobile communication function and a wired discontinuous mobile communication function, with the wireless mobile communication function including one or more wireless mobile communication technologies, such as 2G GSM/GPRS, IS95A/B, IMT-2000 WCDMA, CDMA2000, TD-SCDMA, and so on. Logically, the multi-mode and multi-network user equipment of the invention is divided into two independent functional entities: a wired discontinuous mobile communication user equipment and a wireless mobile communication user equipment. The multi-mode and multi-network user equipment of the invention determines the enabling/disabling of the logic function entities according to a single-network attribute or a multi-network attribute of the universal subscriber identify module in the universal integrated circuit card, along with the actual access type of the user equipment.  
         [0009]     Compared with present wired communication user equipment, the user equipment and method thereof preserves the advantages of wired communication while implementing a wired discontinuous mobile communication function, thereby overcoming the deficiencies of the present wired communication user equipment, such as fixing, stillness, and so on. Moreover, a converging wireless/wired multi-mode and multi-network user equipment of the invention provides wireless mobile communication with the possibility of sharing the numerous advantages of wired communication in a wired communication environment.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0013]     A detailed description of an user equipment and the method thereof according to the invention will be given below in conjunction with the accompanying drawings.  
         [0014]      FIG. 1  is a structural implementation of the user equipment with the wired discontinuous mobile communication function of the invention, namely it is the principle structural diagram of a wired single-mode user equipment. The wired single-mode user equipment  100  comprises a wired mobile equipment  101 , a terminal equipment  102  and a universal integrated circuit card  103 . The wired mobile equipment  101  comprises a wired mobile termination  101   a  and a termination adaptor  101   b,  and the wired mobile termination  101   a  comprises a network termination  101   a   1  and a wired termination  101   a   2 . The universal integrated circuit card  103  comprises a universal subscriber identify module arranged therein. The network termination  101   a   1  is connected to the wired termination  101   a   2 , through a T reference point interface, and the wired mobile termination  101   a  in the wired mobile equipment  101  is connected to the termination adaptor  101   b  and the universal subscriber identify module in the universal integrated circuit card  103  via the network termination  101   a   1 . The wired mobile equipment  101  is connected to the terminal equipment  102  through an R reference point. The wired single-mode user equipment  100  is connected to external user applications, such as computers, via the terminal equipment  102 , and to a wired access network of a wired discontinuous mobile communication network via the wired termination  101   a   2  of the wired mobile termination  101   a  in the wired mobile equipment  101 .  
         [0015]     The wired mobile equipment  101  in the wired single-mode user equipment  100  is responsible for terminating the wired discontinuous mobile communication network bearer services of a user layer and the functions of all control planes. The wired mobile termination  101   a  is an originating and terminating end of the wired transmission over the wired discontinuous mobile communication network. It meets the various requirements for wired transmission, is able to change the access address and position thereof in a wired access network, transfer and switch to the coverage area of another wired access network via the same wired access technology, and is a service terminal of the wired communication network system that is responsible for terminating communication network system service. The network termination  101   a   1  is responsible for wired discontinuous mobility management and communication management, such as circuit service call control and packet service session management, according to a non-access layer protocol, and is responsible for terminating wired discontinuous mobile core network service. The wired termination  101   a   2  cooperates with the wired access network for wired-access to the discontinuous mobile wired communication network via an access layer protocol. It is responsible for terminating all services employing the wired access technology, and terminates the access layer. The termination adaptor  101   b  is responsible for adaptation and connection between the wired mobile equipment  101  and the terminal equipment  102  through the R reference point. The terminal equipment  102  in the wired single-mode user equipment  100  is a functional device providing subscriber terminal applications. It interoperates with the wired mobile termination  101   a  via the R reference point and the termination adaptor  101   b  in the wired mobile equipment  101 , allowing the subscriber to receive normalized communication services and to terminate communication services transmitted via the wired discontinuous mobile communication network bearer service. It also provides the subscriber with various applications, such as access to computer equipment, with application interface service support. The universal subscriber identify module in the universal integrated circuit card  103  terminates user-independent control functions in the local network, and stores subscriber network attributes, along with subscriber and service information data required for security management, access control, wired discontinuous mobility management, call control, and communication management as the user equipment accesses the wired discontinuous mobile communication network. The service information data comprises management data, such as fixed data including fixed and unique telephone numbers, identification numbers, key data for security algorithms, subscriber network attributes, network access permission information, and so on; temporary network data, such as address information for a current position, wired discontinuous mobility management information, encrypted data, and so on; service-related information, comprising internal data relating to the availability and permission status of various services; some small applications, such as JAVA; and personal subscriber data.  
         [0016]     As shown in  FIG. 1 , the components and functions thereof for the wired single-mode user equipment  100  correspond to those in the wired discontinuous mobile communication network, the wired mobile equipment  101  corresponding to a complete wired discontinuous mobile communication network system, the network termination  101   a   1  corresponding to a switching component, a routing component, and a control component in a wired core network, the wired termination  101   a   2  corresponding to the wired access network, the terminal equipment  102  corresponding to a terminal equipment in an external communication network, and the universal subscriber identify module in the universal integrated circuit card  103  corresponding to a user and user equipment information database in the wired core network.  
         [0017]      FIG. 2  is another structural implementation of the user equipment and wired discontinuous mobile communication function of the invention, namely it is a principle structural diagram for a wireless/wired multi-mode and multi-network user equipment converging a wireless mobile communication function and a wired discontinuous mobile communication function. The wireless/wired multi-mode and multi-network user equipment  200  of the invention comprises a wireless/wired mobile equipment  201 , a terminal equipment  202 , and a universal integrated circuit card  203 . The wired mobile equipment  201  comprises a wireless/wired mobile termination  201   a  and a termination adaptor  201   b,  and the wireless/wired mobile termination  201   a  comprises a network termination  201   a   1 , a wired termination  201   a   2 , and a radio termination  201   a   3 . The universal integrated circuit card  203  comprises a universal subscriber identify module. The universal subscriber identify module may be a wireless/wired multi-network universal subscriber identify module, a wired single-network universal subscriber identify module, or a wireless single/multi network universal subscriber identify module. The wireless/wired multi-mode and multi-network user equipment  200  may operate as the wired discontinuous mobile user equipment or the wireless mobile user equipment if the universal subscriber identify module is the wireless/wired multi-network universal subscriber identify module, as the wired single-mode user equipment if the universal subscriber identify module is the wired single-network universal subscriber identify module, and as the wireless mobile communication user equipment if the universal subscriber identify module is the wireless single/multi network universal subscriber identify module. The network termination  201   a   1  in the wireless/wired mobile termination  201   a  is connected to the wired termination  201   a   2  and the radio termination  201   a   3 , through a T reference point interface, and the wireless/wired mobile termination  201   a  in the wireless/wired mobile equipment  201  is respectively connected to the termination adaptor  201   b  and the universal subscriber identify module in the universal integrated circuit card  203  via the network termination  201   a   1 . The wireless/wired mobile equipment  201  is connected to the terminal equipment  202  via the termination adaptor  201   b,  referring to the R reference point. The wireless/wired multi-mode and multi-network user equipment  200  is connected to external user applications, such as computers, via the terminal equipment  202 ; to a wired access network in the wired discontinuous mobile communication network via the wired termination  201   a   2  of the wireless/wired mobile termination  201   a  in the wireless/wired mobile equipment  201 ; and to a wireless access network in the wireless mobile communication network via the radio termination  201   a   3 .  
         [0018]     Logically, the wireless/wired multi-mode and multi-network user equipment  200  is divided into two independent logic function components: the wired discontinuous mobile communication user equipment logic function component and a wireless mobile communication user equipment logic function component. A wired mobile termination functional component comprising the wired termination  201   a   2  and the network termination  201   a   1 , a wired mobile equipment functional component comprising the termination adaptor  201   b  and a wired mobile termination, the terminal equipment  202 , and the universal subscriber identify module in the universal integrated circuit card  203  altogether form a complete logic function component for the wired user equipment, the specific functions of which are the same as those illustrated and described in  FIG. 1 . A wireless mobile termination function component, comprising the radio termination  201   a   3  and the network termination  201   a   1 , a wired mobile equipment functional component comprising the termination adaptor  201   b  and a wired mobile termination, the terminal equipment  202 , and the universal subscriber identify module in the universal integrated circuit card  203  altogether form a complete logic function component for the wireless user equipment, the functions of which comprise one or more wireless mobile communication technologies such as 2G GSM/GPRS, IS95A/B, IMT-2000 WCDMA, CDMA2000, TD-SCDMA, and so on. Except for the fact that the wired termination  201   a   2  and the radio termination  201   a   3  in the wireless/wired mobile equipment  201  are two comparatively independent components due to big difference in physical hardware implementation between wired access and wireless access, the network termination  201   a   1  converges functions of both the wireless mobile core network and the wired discontinuous mobile core network. The universal subscriber identify module in the universal integrated circuit card  203  also converges the functions of the user and user equipment information databases in the wireless mobile core network and the wired discontinuous mobile core network. The terminal equipment  202  provides a functional device with uniform and same user terminal applications for the wireless mobile network and the wired discontinuous mobile communication network on a communication service platform of the wireless/wired mobile equipment  201 , converging multiple modes and networks.  
         [0019]     As shown in  FIG. 2 , since the user equipment  200  of the invention is a multi-mode and multi-network user equipment, the components and functions thereof in the user equipment  200  respectively correspond to those in the wired discontinuous mobile communication network and the wireless mobile communication network, the network termination  201   a   1  corresponding to a switching component, a routing component and a control component in a wireless mobile core network and a wired discontinuous mobile core network, the wired termination  201   a   2  corresponding to a wired access network, the radio termination  201   a   3  corresponding to a wireless access network, the terminal equipment  202  corresponding to a terminal equipment in an external communication network, and the universal subscriber identify module in the universal integrated circuit card  203  corresponding to user and user equipment information databases in different core networks based on the single/multi network attributes thereof.  
         [0020]      FIG. 3  is a further implementation of the user equipment of this invention, namely an embodiment of a wireless/wired multi-mode and multi-network user equipment in a communication network of wireless mobile/wired discontinuous mobile network convergence.  
         [0021]     Before power is enabled, the universal integrated circuit card  303  or the universal subscriber identify module therein is plugged into the wireless/wired multi-mode and multi-network user equipment  300 . After the power is enabled, the universal subscriber identify module transmits subscriber network attributes, along with subscriber and service information data to the wireless/wired mobile termination  301   a  for detection and attachment. If a subscriber network attribute is a wired single-network attribute, the user equipment  300  disables the logic function component of the wireless mobile communication user equipment, and operates as a wired discontinuous mobile communication user equipment at this point. If the subscriber network attribute is a wireless single/multi network attribute, the user equipment  300  disables the logic function component of the wired discontinuous mobile communication user equipment, and only operates as a wireless mobile communication user equipment at this point. If the subscriber network attribute is a wired/wireless multi-network attribute, the user equipment  300  operates as a wireless/wired multi-mode and multi-network user equipment. If the subscriber network attribute is a wireless/wired multi-network attribute and the user equipment automatically selects between wired access and wireless access, priority is given to wired access, namely, the wireless/wired mobile termination  301   a  in the user equipment  300  first detects whether the wireless/wired mobile termination  301   a  is wire-connected to a wired access network. If the wireless/wired mobile termination  301   a  is wire-connected to the wired access network, the user equipment  300  preferentially enables the logic function component of the wired discontinuous mobile communication user equipment, attempts to access the wired access network, disables the logic function component of the wireless mobile communication user equipment if the access is successful, and operates as a wired discontinuous mobile communication user equipment for wired access communication. If the wired access is unsuccessful or the user equipment  300  is not wire-connected to the wired access network, the user equipment  300  disables the logic function component of the wired discontinuous mobile communication user equipment, and enables the wireless mobile communication user equipment for wireless access communication. If the user equipment  300  is set to manually select between wired access and wireless access, the access type is determined according to the desire of the subscriber and the actual connection of the user equipment  300 .  
         [0022]     The user equipment  300  shown in  FIG. 3  has a wireless/wired multi-network subscriber attribute. At this point, the user equipment  300  has already exited an offline state and entered a wired access network by a wired connection, acquiring wired access to resources via an uplink/downlink control channels of the wired access network. This allows it to interact with the wired discontinuous mobile communication network, and to implement security management, such as access initialization of the user equipment  300 ; the establishment of a wired resource control connection; authentication and authorization; wired discontinuous mobility management, such as access position registration and roaming; as well as communication management, such as the authentication of subscriber service information. At this point, the user equipment  300  is in an idle state. If the subscriber requires further communication services, the user equipment  300  needs to cooperate with the wired communication network, to implement the queuing up and establishment of these communication services, along with the allocation and establishment of wired access resource bearer services, to establish an active communication service connection between user layers, and to manage and maintain normal operation of the communication service connection. At this point, the user equipment  300  is in an active state. After a communication service is terminated, any connection between the user layers is terminated, the communication services queue is cleared, the wired access resource bearer services are released, and finally the wired resource control connection, namely the control connection between the user and the core network, is released. At this point, the user equipment  300  returns to the idle state. If the user equipment  300  terminates the wired connection to the wired access network, and is not reconnected thereto in a preset time, the wireless/wired multi-network universal subscriber identify module in the universal integrated circuit card  303  detaches the subscriber network attributes and subscriber and service information for wired communication from the wireless/wired mobile termination  301   a,  storing any necessary data in the universal subscriber identify module in the universal integrated circuit card  303 , and transmitting the subscriber network attributes and the subscriber and service information related to the wireless communication network to the wireless/wired mobile termination  301   a  for detection and attachment. The user equipment  300  then disables the logic function component of the wired mobile communication user equipment, enables the logic function component of the wireless mobile communication user equipment, and accesses the wireless access network and the core network to communicate as a wireless mobile communication user equipment.  
         [0023]     During the processes discussed above for wired discontinuous mobile access and communication, various functional elements in the logic function component of the wired discontinuous mobile communication user equipment in the user equipment  300  of the invention are required to correspond to the functional elements and functions thereof in the wired discontinuous mobile communication network.  
         [0024]     The above embodiments of the invention do not limit the applications of the wireless/wired multi-mode user equipment in a communication network of wireless/wired network convergence. It is also possible to embody the advantages of the invention via applications of the wired user equipment of the invention in a wired discontinuous mobile communication network, applications of the wireless/wired multi-mode user equipment in a multi-network environment with an independent wireless mobile communication network and a wired discontinuous mobile communication network, and implementation of other services.
