Problems solved by technology

[0012] Since PS handover is required before performing CS services, the process of PS handover includes handover preparation and handover execution stages, which takes a long time and causes a large delay. Therefore, the connection time of CS services is increased, which will bring In addition, when you need to perform some special services, such as emergency calls 110 and 112, you need to initiate a call immediately and connect to the CS service as quickly as possible. At this time, if there is an ongoing PS service, you must The PS service must be switched to the PS domain in the GPRS / UMTS network first, and the delay caused by the switch cannot meet the timeliness requirements of these special services
[0013] Furthermore, since the existing 2G system cannot support CS and PS services at the same time, that is, the PS service must be suspended while the UE is performing the CS service
Therefore, even if the PS service in the EPS network is switched to the PS domain of the 2G system at this time, the PS service cannot be used while the CS service is in progress. At this time, the switching of the PS service is meaningless, resulting in a waste of resources

Embodiment 1

[0064] When performing CS fallback processing, the UE may be the originating caller and perform MO services; it may also be the receiving caller and perform MT services; when performing MO services, the first embodiment of the service suspension method provided by the embodiment of the present invention is as follows Said:

[0065] When the UE is about to initiate the CS service, the EPS network is required to reserve the bearer of the UE on the EPS network. If the PS service is in progress, the EPS network buffers the downlink data, and the UE stops sending uplink data. After the UE sends the service suspension request, it can transfer to the 2G / 3G network and select a suitable cell to carry out the CS service; it can also transfer to the 2G / 3G network to carry out the CS service after receiving the response sent by the network side. service; the network can also reject the suspension request, and at this time, the UE needs to wait until the PS service is switched to the dest...

Embodiment 2

[0347] Embodiment 2 of the mobility management entity provided by the embodiment of the present invention includes:

[0348] A second tracking area update request processing unit, configured to receive a tracking area update request message sent by the user equipment;

[0349] The third context unit is configured to send a context request message to the old mobility management entity; receive a context response message sent by the old mobility management entity, and acquire a suspended packet recorded by the user equipment in the old mobility management entity The context of exchanging domain business information;

[0350] A third service recovery unit, configured to send a request for service recovery to the serving gateway, so as to recover the suspended PS domain service;

[0351] The second location update unit is configured to initiate a location update process with the home user server, obtain the subscription data of the user equipment, and register with the home user ...

Abstract

The invention discloses a service suspension method, which comprises: when an user equipment stationed in a group field needs to initiate a circuit field service, the core net equipment of the group field reserves the group network resource of the user equipment according to received indication; when the user equipment is performing a service, saves the descending service data and / or stopping sending the up-link data of the user equipment, and converts to circuit field communication network to perform circuit field service; or, when the user equipment is not performing service, then converts to circuit field communication network to perform circuit field service. The invention further discloses a corresponding treatment system for returning the circuit exchange field service to the conventional network, a user equipment, an evolvement base station, a mobility management entity, a service gateway and a group data network. Applying the invention can reduce the time delay before CS service while processing CS fallback, and further avoids resource waste.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for suspending a service, a method, a system and a device for resuming a service. Background technique [0002] General Packet Radio Service / Universal Mobile Telecommunications System (GPRS / UMTS, General Packet Radio Service / Universal Mobile Telecommunications System) is a mobile communication network defined by the Third Generation Partnership Project (3GPP, The 3rd Generation Partnership Project), which includes wireless Access network (RadioAccess Network, RAN) and core network (CoreNetwork, CN) two parts. Wherein, the CN is logically divided into a circuit switched domain (Circuit Switched Domain, CS) and a packet switched domain (Packet Switched Domain, PS). The CS domain mainly handles voice services, and the PS domain mainly handles packet data services. [0003] In order to adapt to the development of wireless broadband technology, 3GPP has formu...
