Embodiment 1

[0028] like figure 2 As shown, in the present embodiment, in the WCDMA system, the PS I / B class service is set up on the HS-DSCH channel, and a normal process of HS-DPCCH power adjustment is performed when the channel performs soft handover between Nodebs (after the new link is set up) Report the wireless link recovery indication before the timer expires), specifically including the following steps:

[0029] Step 210, the UE initiates a PS I / B class service in a cell belonging to Nodeb-old (formerly NODEB), and the service is established on the HS-DSCH channel;

[0030] Step 215, the UE reports that the wireless quality of the cell (belonging to Nodeb-new (new NODEB)) adjacent to the original cell reaches the reporting range of the 1a (or 1d) event;

[0031] Step 220, SRNC sends a wireless link establishment request message to Nodeb-new;

[0032] Step 225, SRNC receives the wireless link establishment response message that Nodeb-new sends;

[0033] Step 230, the SRNC sets ...

Embodiment 2

[0045] like image 3 As shown, in this embodiment, in the WCDMA system, the PS I / B class service is set up on the HS-DSCH channel, accompanied by an abnormal process of HS-DPCCH power adjustment when the channel performs soft handover between Nodebs (after the new link is established The wireless link recovery indication is not reported within the timer time), which specifically includes the following steps:

[0046] Step 310, the UE initiates a PS I / B type service in the cell where it resides, and the service is established on the HS-DSCH channel;

[0047] Step 315, the UE reports that the wireless quality of the cell (belonging to Nodeb-new) adjacent to the original cell reaches the reporting range of the 1a (or 1d) event;

[0048] Step 320, SRNC sends a wireless link establishment request message to the Nodeb-new;

[0049] Step 325, SRNC receives the wireless link establishment response message that Nodeb-new sends;

[0050] Step 330, the SRNC sets a timer and waits for ...

Abstract

The invention discloses a control method of the high speed special physical control channel power under the soft switch state, including: initiating the operation built on the high speed down sharing channel in the resident district of the user equipment, sending the wireless link building request to a new node B when the service wireless network controller judges to perform the soft switch, receiving the wireless link recover indicating information of arranging a timer and waiting for the new node B after the wireless link builds the response; if the wireless network controller receives the wireless link recover indicating information of the new node B before the timer overtimes, the service wireless network controller transmits the information to the user equipment and the original node B, else, the service network controller deletes the newly built wireless link. The invention shortens the time in the unstable state of UE, reduces the unnecessary signalling spending of the IUb port and the Uu port, relieves the load of the system process, advances the integral operating performance of the 3G system.

Description

technical field [0001] The invention relates to a power control method in a wireless communication system, in particular to a HS-DPCCH (High Speed ​​Dedicated Physical Control Channel) power control method in a soft handover state. Background technique [0002] The third generation mobile communication system includes a WCDMA (Wideband Code Division Multiple Access) system. For the HSDPA (High Speed ​​Dwonlink Packet Access) service, when the accompanying channel is in the soft handover state, the HS-DPCCH will be affected when the transmit power is reduced due to the soft handover gain of the DPCCH (Dedicated Physical Control Channel) probability of correct acceptance. In order to optimize the performance of HSDPA, SRNC (Serving Radio Network Controller) needs to support the configuration of HS-DPCCH power deviation according to the soft handover state. To this end, SRNC provides two sets of HS-DPCCH power control parameters, mainly including ACK (Acknowledgment packet co...
