Abstract
The invention discloses a processing method of a radio link increase procedure. The processing method comprises the following steps: when a drift radio network controller fails or partially fails to increase the radio link and succeeds in changing a high-speed downlink packet access service link simultaneously, the drift radio network controller returns a radio link increase failure message to a service radio network controller and adds information for instructing a terminal to cancel reset to the radio link increase failure message; a source service link and a target service link in the service link change process are in the same base station of the drift radio network controller side, and data transit can be performed after the service link is changed. The invention also discloses a corresponding system and the drift radio network controller. The processing method, the system and the drift radio network controller can ensure un-reset state of MAC-hs in the base station and MAC-hs in the terminal of the drift radio network controller side.
Description
Technical field
The present invention relates to the mobile communication technology field, particularly a kind of processing method of wireless link increment process, system and floating radio network controller.
Background technology
Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, WCDMA) switching in the system comprises soft handover, described soft handover is terminal takies the multi wireless links in the air interface simultaneously in handoff procedure switching.
Fig. 1 shows the schematic diagram of terminal execution soft handover in the WCDMA system.The WCDMA system comprise core net (Core Network, CN), radio network controller (Radio Network Controller, SRNC), base station (NodeB).RNC can be divided into Serving RNC (Serving RNC according to function, SRNC) and Drift Radio Network Controller (DriftRNC, DRNC), wherein, Serving RNC is for current terminal provides the RNC that is connected to core net, and Drift Radio Network Controller is the RNC at the new Target cell place selected of described user.CN is connected with SRNC by the IU mouth, and SRNC is connected with DRNC by the IUR mouth, and SRNC is connected with NodeB by the IUB mouth, and DRNC also is connected with NodeB by the IUB mouth.
As shown in the figure, when terminal during from the base station of 1 soft handover of the base station under the SRNC under DRNC, select proper cell by SRNC according to measurement report, find DRNC by SRNC, notice DRNC increases Radio Link, and DRNC carries out the wireless link increment process of striding the IUR mouth.The Radio Link of striding the IUR mouth increases process and can comprise as shown in Figure 2:
Step 201:SRNC sends Radio Link increases request (RADIO LINK ADDITIONREQUEST) message to DRNC;
Step 202:DRNC carries out Radio Link increases process, if Radio Link increases successfully, then return Radio Link and increase response (RADIO LINKADDITION RESPONSE) message to SRNC, if Radio Link increases failure or part failure, then return Radio Link increase failure (RADIO LINKADDITION FAILURE) message and give SRNC.
Increase when Radio Link under the situation of failure or part failure, high speed medium access control layer (MAC-HS) entity among the DRNC (Medium Access Control-High Speed, MAC-hs) need reset, and increase failed message by Radio Link and also carry out MAC-hs by SRNC notice terminal and reset.
