Embodiment Construction

[0029]The present invention adopts modification mode to control UE's business to switch from DCH to HS-DSCH, and its basic principle is: if RNC finds that certain business of UE needs to be switched from DCH to HS-DSCH (that is, the CELL_DCH state that HS-DSCH has never been started to receive Transition to the CELL_DCH state that starts HS-DSCH reception), the RNC configures the HS-DSCH for the service in the NBAP / RNSAP signaling, and at the same time indicates that the DCH modification method is used to reconfigure the DCH, and clearly indicates that the DCH of the service is a unidirectional DCH . After Node B / DRNC receives it, the downlink CCTrCH no longer contains the DCH of the service, and the uplink configuration of the DCH remains unchanged; then, the RNC instructs the UE to delete the downlink DCH of the service through RRC signaling, and add the HS-DSCH of the service configuration, the uplink DCH configuration of this service remains unchanged.

Abstract

The invention relates to a method for switching the service from DCH to HS-DSCH. Wherein, when SRNC decides to switch the service of UE from DCH to HS-DSCH, informing the node B of UE to use one-way DCH and modification on the service to reset, with the setting information with service HS-DSCH; the node B receives information and completes the setting of HS-DSCH; deleting DCH of said service in the descending CCTrCH, and keeping the ascending DCH; the feeding back response to SRNC; SRNC receives response to start relative lub and lur ports to transmit loaded dynamic modification and inform UE to delete descending DCH of said service, with the setting information of service HS-DSCH; UE receives and completes the setting of HS-DSCH, and deletes the DCH in descending CCTrCH, without changing ascending DCH. The invention can avoid ineffective consumption of system resource, to improve the processing efficiency of RAN system and UE.

Description

technical field [0001] The invention relates to a channel switching method of a Wideband Code Division Multiple Access (WCDMA) mobile communication system. Background technique [0002] In the WCDMA mobile communication system, the basic operation mode of mobile terminal UE (User Equipment) is divided into idle mode and connection mode, and the connection mode can be further divided into different service states, including: CELL_DCH, CELL_FACH, CELL_PCH and URA_PCH states. Such as figure 1 shown. These traffic states define the type of physical channel used by the UE. In the CELL_DCH (Dedicated Channel, dedicated transmission channel) state, the radio access network RAN ​​(Radio Access Network) needs to allocate a dedicated physical channel for the UE. In the CELL_FACH (Forward Link Access Channel) state, the UE does not occupy a dedicated physical channel, and uses the RACH (Random Access Channel) and FACH common channels to transmit signaling messages and a small amount...
