Problems solved by technology

[0011] The purpose of the present invention is to provide a method for selecting a recovery data mode and a radio network controller, which are used for HSDPA cell handover, so as to ensure that the RNC can clearly select the recovery data mode, so as to solve the possible problems caused by the fact that the RNC does not know which mode to choose. increase transmission delay and occupy air interface resources, and improve the performance of HSDPA in cell handover

Embodiment 1

[0062] like figure 2 As shown, embodiment one includes:

[0063] Step 201: RNC initiates a wireless link establishment request to Node B;

[0064] Step 202: Node B returns to the RNC a wireless link establishment response, which includes information about whether Node B supports MAC-hs entity data retention;

[0065] Wherein, a field information is added in the radio link establishment response to identify whether the Node B supports MAC-hs entity data retention.

[0066] If the Node B supports MAC-hs entity data retention, execute step 203, step 204, and step 205; otherwise, execute step 204, step 205, and step 206.

[0067] Step 203: Node B moves MAC-hs entity data;

[0068] Step 204: The RNC initiates a handover request to the UE, wherein, according to step 202, it is judged whether it is necessary to include an indication that the UE resets the MAC-hs entity in the handover request;

[0069] If the radio link establishment response in step 202 indicates that the Node ...

Embodiment 2

[0075] see image 3 Shown, embodiment two comprises:

[0076] Step 301: RNC sends a MAC-hs entity data retention query request to Node B;

[0077] Step 302: Node B responds to the MAC-hs entity data retention query request, and informs itself whether it supports MAC-hs entity data retention;

[0078] Step 303: RNC initiates a wireless link establishment request to Node B;

[0079] Step 304: Node B returns a wireless link establishment response to RNC;

[0080] If the Node B supports the MAC-hs entity data retention function, execute steps 305, 306, and 307; otherwise, execute steps 306, 307, and 308.

[0081] Step 305: Node B moves MAC-hs entity data;

[0082] Step 306: The RNC initiates a handover request to the UE, wherein, according to step 302, it is judged whether the handover request needs to include an indication that the UE resets the MAC-hs entity;

[0083] Step 307: The UE performs a corresponding handover operation according to the handover request; and returns...

Abstract

Being applicable to switching HSDPA sector, the method includes steps: RNC corresponding to base station belonging to the subzone obtains whether base station supports data retention of MAC-hs entity; RNC initiates switching request on user equipment being in switching subzones; if base station supports data retention of MAC-hs entity, then the switching request does not contain indication for resetting MAC-hs entity; otherwise, the switching request contains indication for resetting MAC-hs entity. Obtaining information whether base station supports data retention of MAC-hs entity or not, theinvention makes RNC possible to select two modes for recovering data. In precondition that known base station supports data retention of MAC-hs entity, the method prefers this mode in order to improve data transmission time delay in aerial port, and raise efficiency of using aerial port. The invention also discloses a wireless network controller.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for selecting a recovery data mode applied to HSDPA cell switching and a wireless network controller. Background technique [0002] High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Packet Access) is a high-speed downlink data transmission technology proposed in 3GPP (3rd Generation Partner Project, Third Generation Partnership Project) R5. HSDPA is mainly accomplished by introducing the High Speed ​​Downlink Shared Channel (HS-DSCH) to enhance the air interface and enhancing the corresponding functional entities in the Universal Mobile Communication System Radio Access Network (UTRAN). [0003] From the bottom layer, it is mainly to introduce adaptive modulation coding (AMC) and hybrid automatic retransmission mechanism (HARQ) technology to increase data throughput. From the point of view of the overall structure, it mainly enhances the pr...
