Description of the Invention: [Technical Field] The present invention relates to a method for improving paging efficiency of a wireless communication system and related devices, and more particularly to a method for improving paging efficiency and avoiding transmission interruption and preventing packet loss. Method and related devices. [Prior Art] Multimedia Broadcast Multicast Service (MBMS) is a point-to-multipoint data transmission service to enhance the multimedia functions of the third generation mobile communication system, which is built on the global mobile communication system ( The Universal Mobile Telecommunications System (UMTS) network architecture is based on the Internet Protocol (Intemetpr〇t〇c〇l, positive) packet, allowing a single data source to simultaneously deliver the same service to multiple clients. . The LongTerm Evolution (LTE) wireless communication system is an advanced high-speed wireless communication system built on a third-generation mobile communication system (such as the Global Mobile Telecommunications System), which only needs to support packet-switched transmission. The wireless link control protocol layer and the media access control protocol layer are integrated in the same communication protocol layer, so the system architecture is simple. At present, the structure of the long-term evolution wireless communication system is still in the technical report (Ding Shenru (10) Kiss (10)), and there is no formal agreement. In the current known architecture, the Long Term Evolution (LTE) wireless communication system also supports the multi-200818768 media broadcast and multicast services to enhance multimedia functions. In the squirting process, the long-term evolution wireless communication system can use two different types of signals to cover the coverage of the base station.) Provide multimedia broadcasting and group broadcasting services': special cells for broadcasting and group broadcasting services (10) paper secrets (3) (four) (four), another For the cell (Mlxed Cell). The so-called hybrid cell system refers to the base station (4) that can provide non-multimedia broadcast and multicast services and multimedia broadcast and multicast services simultaneously, while the multimedia broadcast and multicast service dedicated cells are specifically used to provide multimedia. The coverage of the base stations of the broadcasting and multicast services, that is, the cells for multimedia broadcasting and multicast services do not support unicast service. Since the long-term decision-making wireless communication system uses two different types of base stations to provide multi-ship broadcasting and multicast services, the user-side configurable_receiving n, respectively, is formed by the special cells and mixed cells of the multimedia broadcasting and group broadcasting services. Frequency layer _ (FrequeneyLayer·) 'The ribs are connected to the media and the cells provided by the cells. The frequency layer refers to a group of cells of the same type. On the other hand, if the UE only configures a single receiver, when the UE wants to receive the multimedia broadcast and the multicast service, it must move to the frequency layer of the dedicated cell for the multimedia broadcast and the multicast service to find a good financial service. In the format, when the UE receives the multimedia broadcast and the multicast service through the single-receiver, the conventional technology provides different location update methods in order to prevent the user from missing the call, so that the network can take the user's end. Location poor, for paging users in multimedia broadcast and multicast service dedicated cells. 6 200818768 In order to make the terminal know that the user _ is being lighted, the conventional technology provides a method that is terminated when the user changes the tracking area (for example, when moving between different cells), the user should stop. Receiving the current multimedia broadcast and multicast service and returning to the frequency layer supporting the one-way transmission service, thereby performing the location update process. In this way, the network can know the location of the client to facilitate paging. However, the client must suspend the reception of the current multimedia broadcast and multicast service by the above method. In addition to the interruption of the transmission, the packet may be lost, thus affecting the quality of the multimedia broadcast and the multicast service. In another prior art, the network will page all the cells in the final tracking area of the client'. In addition to the reduced fee, in some cases, the paging may not be completed correctly, for example, The client is in the frequency layer check mode of the unidirectional data transmission service, and the terminal is in the frequency layer of the (four) body broadcast and multicast service dedicated cells but operates in the idle mode (10)e), or the UE leaves all the provided multimedia broadcasts. And cells of the group service. * In addition, the 'other-known technology is first established - the neighboring cell table of the user side, as a reference for = call. When the UE receives a message from the frequency layer of the multimedia broadcast and the multicast service, the UE performs cell selection to switch to the frequency layer of the one-way data transmission service. However, the process of cell reselection causes a paging delay, and this method does not take into account the mobility of the client, causing the neighboring cell table of the user terminal to be difficult to establish. SUMMARY OF THE INVENTION 7 200818768 Wireless Communication System Improvements Accordingly, it is a primary object of the present invention to provide a method of paging efficiency and related apparatus. The present invention discloses a service for improving paging efficiency in a wireless communication system, a service provided by a user terminal of a wireless communication 5fl system, a multimedia broadcast and a multicast service, and a wireless communication system. When one of the network terminals receives an incoming call corresponding to one of the client terminals, the network terminal is based on the user terminal.

Preferably, the wireless communication device is applied to a long term evolution wireless communication system. The first picture can be taken, and the second picture is the functional block diagram of the wireless communication device. For the sake of brevity, FIG. 1 only depicts the wireless communication device touch-input device, an output device 104, a control circuit hall, a central processing unit (10), a storage device 110, a code 112, and a transceiver 114. . In the touch of the wireless communication device, the control circuit 1% through the central processing unit should execute the code 112' stored in the storage device 11', and then (4) the material of the device (8), which can be received through the input device 102 (such as a keyboard). The signal input by the user, or through the output device 〇4 (such as screen, gamma, etc.) to turn out the surface, sound and other signals. The transceiver ΐ4 is configured to receive or transmit a wireless port and transmit the received signal to the control circuit room or to wirelessly output the signal generated by the control circuit 106. In other words, with a communication protocol. Please continue to refer to Figure 2, which is a schematic diagram of the code 112 in Figure 1. The code 112 & contains an application layer 2 〇〇, a third layer interface 2 〇 2 and a second layer surface 206 ′ and is connected to the - layer interface. The third layer interface 2〇2 is used for resource control, the second layer interface is 2〇6帛 for chain control, and the first layer interface 218 is used for entity connection. As mentioned above, when the UE receives the multimedia broadcast and the multicast service through the single-receiver, in order to prevent the user from missing the incoming call, the network needs to page the client. In this case, the embodiment of the present invention provides a paging code 22 in the code m, and uses 9 200818768 to efficiently and non-disruptively page a client in the multimedia broadcast and multicast service dedicated cells. In order to implement the program code no, the embodiment of the present invention provides different processes for the user end and the network end respectively. Please refer to Fig. 3 and Fig. 4, Fig. 3 and Fig. * for the implementation of the weaving process 3G and * wire @. Touch 3G Secret - the user side of the wireless communication system (4) to extract the scale of the call, which can be compiled into 220. The process 30 includes the following steps: Step 300: Start. Step 302: Receive a service provided by a cell dedicated to multimedia broadcast and multicast service. Step 304: Start-track the area update process to update the information of a tracking area. Step 306: Receiving a page message through at least one cell of the 0H tracking area. Step 308: End. The process 4 secret - wireless communication secret cymbal, ribs improve the efficiency of paging, which can be compiled into paging code 22 〇. The process 40 includes the following steps: Step 400 · Start. Step 402: One of the terminals of the ahai wireless communication system receives a service provided by a dedicated cell for multimedia broadcast and multicast services. Step 404: When receiving an incoming call corresponding to the one of the UEs, according to a result of the tracking area update process of one of the user terminals, at least one cell of the tracking area of one of the UE1818768 outputs a paging message for paging. The client. Step 406: End. According to the processes 30 and 40, the embodiment of the present invention is to receive a service provided by a multimedia broadcast and multicast service dedicated cell at the user end, and the tracking end area update process is initiated by the user end to update the information of the tracking area of one of the user terminals; When receiving the call corresponding to one of the user terminals, the network may output a paging message through at least one cell of the tracking area of the user terminal to page the user end according to the result of the tracking area update process. In this way, the network does not need to page all the cells in the final tracking area of the UE to avoid wasting system resources, and the UE does not need to stop receiving the current multimedia broadcast and multicast service to perform the location update process. Avoid transmission interruptions and prevent packets from being lost. Preferably, in the process 30, the user end performs the uplink transmission, such as receiving, transmitting, and transmitting the system information transmitted by the paging message or the system information generated by the user terminal. The tracking area update process is performed by taking the multimedia broadcast and multicast service dedicated cells or mixed cells, and the link channel table. Preferably, the user terminal can receive the identification data of the tracking area broadcasted by the network terminal through the control channel to obtain the tracking area stored in the dedicated cell or the mixed cell of the multimedia broadcasting and the group broadcasting service. . Preferably, when the user receives the paging message or the incoming call, the system uses the system to transmit the message through the uplink or through a cell reselection process, and the message is responsive to the message; wherein, the user is connected to the device (4) The cell reselection process is performed before the paging message or when receiving the 200818768 ί. _ to the message. Preferably, in the process 40, at least one cell line belongs to a frequency layer of a dedicated cell for multimedia broadcast and multicast service, and the network can output a paging message through a dedicated beer channel or a broadcast channel. Call the client. Preferably, the network can maintain information corresponding to the user end, such as whether the user enters the user- (four) body broadcast and multicast service dedicated cells, whether the user side adds people - multimedia broadcast and group broadcast service, and 10 households Receive capability (single- or dual receiver)#. In this way, the network can decide how to page the client based on the above information. It can be seen from the above description that in the frequency layer of the multimedia broadcast and multicast service dedicated cells, the synchronization mode of the user's downlink transmission is the same as the synchronization of the transmission of the paging message, and the uplink transmission can be implemented in one. Dedicated, shared or random access channels In addition, the synchronization of the link transmission on the client side can be calculated by using the timing of the tracking process to obtain the gap between the start time and the start time. Synchronization timing when winding up. As described above, the embodiment of the present invention does not need to establish a reference of a neighboring cell of a user terminal as a paging. At the same time, when the network receives all the cells corresponding to one of the user terminals, the router, and the final tracking area of the user terminal, the "good resource" resources are avoided, and the user does not need to stop. Receive the current multimedia broadcast and group broadcast service money to read and update the wire, so that you can thieves, prevent the package • Lost. 12 200818768 The above is only a preferred embodiment of the present invention, and all changes and modifications made by the patent application of the present invention are within the scope of the present invention.
