Problems solved by technology

[0006] 1) The terminal works in multiple modes at the same time, because it needs to perform location update in multiple networks and listen to paging messages from multiple network sides, which will inevitably cause excessive location update signaling overhead and energy consumption
[0007] 2) If the terminal only works in one mode at a certain time, it will reduce the location update signaling overhead and save the limited energy of the terminal, but it cannot effectively monitor the network side paging messages from other inactive modes, making non-active Network communication in active mode cannot be effectively established
[0008] Therefore, there is a need for a paging solution in a heterogeneous network, which can effectively solve the conflict between dual / multi-mode terminals monitoring paging messages on the network side and energy consumption

The main function is the functional interface with the external IP packet network. The GGSN needs to provide the gateway function for the device to access the packet network ou...

Embodiment 2

[0090] Figure 8 A schematic diagram of a wide area network and a heterogeneous network topology of the wide area network according to Embodiment 2 of the present invention is shown.

[0091] exist Figure 8 In, WCDMA network and figure 1 The shown WCDMA network topology is the same, and the GSM network also adopts the traditional GSM network configuration. Among them, BTS is a base transceiver station, used for wireless transmission; BSC is a base station controller, used for control and management, and the WCDMA network and the GSM network overlap each other. For the sake of brevity, a detailed description of the traditional GSM network configuration is not given here.

[0092] according to Figure 8 In the shown network topology, the GSM network and the WCDMA network can be divided into primary and secondary, and can also be switched between each other.

Abstract

The invention provides a heterogeneous network paging method and system, and terminal used for heterogeneous network. The heterogeneous network comprises at least a first network and a second network. The method comprises: in the overlap field of at least the first and the second network, when a paging request appears in the second network, searching the destination terminal which does not work in the second network mode and its registered position information in the first network mode; while the terminal works in the first network mode, adding heterogeneous paging indication information in the paging message meaning that the paging from the second network exists into the first network mode; carrying out paging according to the found position information and the paging message with heterogeneous paging indication information and informing the terminal to open the second network mode.

Description

technical field [0001] The present invention relates to the field of wireless communication networks, in particular to a paging method and system for a heterogeneous network, and a terminal for the heterogeneous network. Background technique [0002] In the wireless communication network, the purpose of the wireless communication system to manage the location of the host / terminal is to enable the system to locate and track the location of the host / terminal that may roam or move at any time, and then accurately deliver the call or group to the destination mobile host / terminal. capabilities of the terminal. The concepts involved in location management in mobility protocols include location update and paging. The wireless communication network must track and record the location information of the mobile station, so that the incoming call can be delivered to the correct user as required. [0003] According to the order of each sub-process, the first thing to happen is the loca...
