Network concealed separation method of subscriber terminal

Abstract

The present invention relates to a network implicit separation method of a user terminal, comprising: after the user terminal is registered in the long-term evolution network and the 2G / 3G network, establishing an associated user terminal between the two networks; in one network, the user terminal enters an idle state , the network node starts the mobile reachable timer of the user terminal; after the mobile reachable timer of the network node expires, the user terminal is set to the quasi-hidden separation state, which is also true if the user terminal is in another network Implicit separation state, the two networks implicitly separate the user terminal, and the mobility management state of the user terminal on the network is set to the separation state. Therefore, in the separation method of the present invention, the two network nodes independently control the mobility management context of the user terminal, and when the downlink data arrives, paging is only performed in the currently camped RAT network; the impact on the existing system is as little as possible; two The associated context synchronization signaling between networks saves network resources.

Description

technical field [0001] The present invention relates to a network implicit separation method of a user terminal (User Equipment, UE), in particular to a method for implicit separation of a user terminal in a dual access system of an evolved network. Background technique [0002] At present, in 3GPP (3rd Generation Partnership Project, third-generation cooperation project), SAE (System Architecture Evolution, system architecture evolution), LTE (Long Term Evolution, long-term evolution) are being studied more and more, and the purpose of LTE is to provide A low-cost network capable of reduced latency, increased user data rates, improved system capacity and coverage. Only PS domain services are used, and the bearer network is IP bearer. [0003] On this basis, many new network architectures have been derived to meet the above requirements, such as figure 1 Shown is a relatively common architecture, in which LTE RAN is the radio access network of the evolved network, and the ...

AI Technical Summary

Problems solved by technology

[0066] 1. Every time the UE performs periodic RAU process or O&M operation (such as adjusting the periodic RAU timer, etc.), it needs to perform association synchronization update between the two RAT systems, wasting network resources

[0067] 2. When the UE enters the IDLE state and stays in one RAT for a long time, when the downlink data arrives, it always needs to perform paging in the two RAT systems, wasting network and air interface resources

[0073] 1. When the UE stays on the slave network for a long time, the UE needs to synchronize with the master network node during the periodic RAU process, which wastes network resources

[0074] 2. For UEs in IDLE state, when downlink data arrives, paging is always performed in the two systems, wasting network and air interface resources
