Abstract

The invention discloses a method for suspending a packet data service, which comprises the following steps of: receiving a user equipment context release request message sent by an evolution base station, wherein the user equipment context release request message comprises a redirection circuit domain service backspacing indication; according to the redirection circuit domain service backspacing indication, starting a timer; and if a context request message which is sent by a Serving GPRS (General Packet Radio Service) Support Node SGSN of a target network according to the triggering of user equipment is still not received after the timer is timed out, suspending the packet data service on a source network. According to the method disclosed by the invention, under the condition that a target cell does not support a DTM (Dual Transfer Mode), the UE triggers a Mobility Management Entity (MME) of the source network to suspend the packet data service on the source network or the target network and the UE can accurately know whether the target cell supports the DTM, and thus, the packet data service is avoided being wrongly suspended or not being suspended.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for suspending packet data services. Background technique [0002] With the development of mobile communication technology, more and more mobile communication systems have appeared, such as the second generation mobile communication system (2 nd -Generation, 2G) GSM (Global System For Mobile Communication, Global System for Mobile Communications), which belongs to the third generation mobile communication system (3 rd -Generation, 3G) WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access), CDMA2000 (Code Division Multiple Access 2000, Code Division Multiple Access 2000), TD-SCDMA (Time Division-Synchronous CDMA, Time Division Synchronous Code Division multiple access), and the LTE (Long Term Evolution, Long Term Evolution system) network under development and construction. [0003] In the early stage of LTE network constr...
