Problems solved by technology

In the IOPS mode, since the eNB or NeNB has no loop or the loop is limited, the MME cannot initiate paging to the UE.
However, the prior art does not provide an effective solution for realizing the paging process of the UE in the IOPS mode

[0221] The first embodiment, such as Figure 9 As shown, the number of eNBs or NeNBs in the IOPS networking is 3, and a mesh network topology can be adopted. Each eNB or NeNB in ​​the IOPS network maintains a PAL master table, and sets a timer for each eNB or NeNB, and the timers are synchronized (the Global Positioning System (GPS, Global Positioning System) can be used for synchronization). The PAU update period is set according to the situation of the UE (such as the mobile rate of the UE, etc.). The smaller the UE's mobility rate, the longer the PAU update period; the greater the UE's mobility rate, the shorter the PAU update period.

[0222] When the timer period arrives, the UE can be triggered to perform the PAU process (that is, the UE is triggered to send a PAU request message to the eNB or NeNB), and the eNB or NeNB refers to the current location information of the UE and the situation of the UE (such as the speed and movement trajectory of the UE ( The rate is hig...

[0223] Second embodiment, such as Figure 10 As shown, the number of eNBs or NeNBs in the IOPS network is 5, and a star network topology can be adopted. Use one of the eNBs or NeNBs in the IOPS network as a centralized controller to manage the PAL tables in all eNBs or NeNBs. A timer is set for each eNB or NeNB, and the timers are synchronized (Global Positioning System (GPS, Global Positioning System) may be used for synchronization). The PAU update period is set according to the situation of the UE (such as the mobile rate of the UE, etc.). The smaller the UE's mobility rate, the longer the PAU update period; the greater the UE's mobility rate, the shorter the PAU update period.

[0224] When the timer period arrives, the UE can be triggered to perform the PAU process (that is, the UE is triggered to send a PAU request message to the eNB or NeNB), and the eNB or NeNB allocates a PAL for the UE according to the current location information of the UE. When the PAL of the UE is...

[0225] The third embodiment, such as Figure 11 As shown, the number of eNBs or NeNBs in the IOPS network is 4, and a star network topology can be adopted. Use one of the independent network elements in the IOPS network as a centralized controller to manage the PAL tables in all eNBs or NeNBs. A timer is set for each eNB or NeNB, and the timers are synchronized (Global Positioning System (GPS, Global Positioning System) may be used for synchronization). The PAU update period is set according to the situation of the UE (such as the mobile rate of the UE, etc.). The smaller the UE's mobility rate, the longer the PAU update period; the greater the UE's mobility rate, the shorter the PAU update period.

[0226] When the timer period arrives, the UE can be triggered to perform the PAU process (that is, the UE is triggered to send a PAU request message to the eNB or NeNB), and the eNB or NeNB allocates a PAL for the UE according to the current location information of the UE. When ...

Abstract

A place area list (PAL) managing method and device as well as a paging method and device. The PAL managing method comprises: after isolated evolved-universal terrestrial radio access network (E-UTRAN) operation for public safety (IOPS) networking is completed, an eNB or NeNB allocates a PAL to a UE after a preset allocation condition is satisfied (200); the eNB or NeNB saves the allocated PAL or updates a saved PAL by using the allocated PAL, and sends the allocated PAL to the UE as well as other eNBs or NeNBs in the IOPS networking or a network element in the IOPS networking (201); and the UE as well as the other eNBs or NeNBs in the IOPS networking or the network element in the IOPS networking saves the allocated PAL or updates a saved PAL by using the allocated PAL (202).

Description

technical field [0001] The present invention relates to an isolated evolved universal terrestrial radio access network operation (IOPS, Isolated E-UTRAN Operation for Public Safety) technology based on public safety, especially a method for managing a location area list (PAL, Place Area List) And device, method and device for realizing paging. Background technique [0002] At present, the trunking communication system is mainly developed to meet the needs of industry users for command and dispatch, and it is a dedicated wireless communication system for specific industry applications. The main feature of the trunking communication system different from the public radio mobile communication system is that in addition to providing the two-way conversation function of the mobile phone, it can also provide group (group) calls and all calls in the system, and even establish call priority levels, and can carry out Priority calls, emergency calls, and other communications that ord...
