Method and apparatus for implementing state transfer in wireless communication system

Abstract

This invention relates to a realization method and a device for the state transfer in a radio communication system including: first of all a network side sets up a radio link accessed by the user terminal after transferring the state and informs the user terminals to switch links in the process of setting up said radio link, secondly, the user terminal receives the inform to switch it to said radio link, therefore, this invention not only meets the needs of communication service demanding high on time but also increases the service quality of user service, besides, this invention can reduce the service load of communication interfaces and reduce information flow in the system.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for realizing state transfer in a wireless communication system. Background technique [0002] In existing wireless communication networks such as WCDMA, UE (mobile terminal) has three channel states in connection mode, that is, UE in connection mode can be in three channel states, and different functions can be realized in different channel states ,details as follows: [0003] (1) CELL_DCH (Cell Dedicated Channel) state: Responsible for allocating dedicated channel resources to UE, allocating dedicated channel codes for downlink, and allocating dedicated scrambling codes for uplink; [0004] (2) CELL_PCH (Cell Paging Channel) state: In this state, no traffic channel is assigned to the UE, but only on the control plane, the downlink connection is maintained through the paging channel, and the uplink connection is maintained through the common control cha...

Problems solved by technology

[0015] It can be seen from the above-mentioned processing procedure that the existing technical solution for UE to transfer between different channel states is implemented in a serial manner, therefore, in the process of link switching, it is necessary to use figure 2 The processing process shown is implemented by executing each step in sequence one by one, and some steps that can be processed at the same time during the link switching process cannot be processed at the same time.

This processing method greatly increases the delay of the channel state transition process in the wireless network system, which in turn makes it impossible to meet the application requirements in some application scenarios that require relatively high delay on the control plane, for example, in group communication services , it is necessary to reduce the delay as much as possible. At this time, if the above method is adopted, the needs of group communication services cannot be met.
