PS service permanent on-line realizing method and apparatus

Abstract

The invention relates to a method for realizing forever online PS service and relative device. Wherein, it comprises: first, when the user of PS (grouped) service has no exchanged information (as signal and data), releasing its occupied L2 (layer 2) connecting resource, and storing the relationship between relative L2 connecting mark and the L3 connecting mark; then, when the user of PS service has exchanged information, according to the stored relationship, building the L2 connection; therefore, user can via this L2 connection exchanges information or process PS service. The invention can release the L2 resource when there is no information exchange, and keep the user online, to save the system resource of RAN (wireless access network). Therefore, the invention can increase the number of online users.

Description

Technical field

[0001] The present invention relates to the field of wireless communication technology, and in particular to a method and device for realizing a permanent online PS service. Background technique

[0002] An important advantage of the WCDMA (Wideband Code Division Multiple Access) system over the 2G (Second Generation Mobile Communication) system is that the processing capability of PS (Packet Domain) services is greatly enhanced. If users can access the PS services and are permanently online It is a very attractive feature.

[0003] If the PS service is permanently online, it can avoid the tedious process of users repeatedly going online and offline, thereby saving the waiting time of the user's access. At the same time, achieving the permanent online PS service can also effectively save the signaling processing burden on the system side. .

[0004] However, realizing that users are permanently online, that is, the permanent online of the PS service requires a lot...
