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

[0061] In the first embodiment, through the aforementioned steps 103 and 104, the Node B actively reports to the SRNC whether it has the data retention function, so that the SRNC decides whether to include the MAC-hs entity reset indication in the sending to the UE in step 107. in the RRC information. In cell handover, DRNC only acts as a data relay, does not always exist, and is not responsible for data transmission. Only the SRNC is connected to the core network (CN), so the data always comes from the SRNC. Therefore, in this embodiment, the process of establishing a wireless link is simplified, mainly the operations related to the DRNC are simplified, and the description is unified with the RNC.

[0062] Such as 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 su...

Embodiment 2

[0074] In addition to the Node B actively responding to inform the RNC whether it supports MAC-hs entity data retention by establishing a wireless link described in the first embodiment, it can also be realized by the RNC actively inquiring the Node B. In this implementation manner, no modification is required for the existing wireless link establishment process.

[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.

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, the invention 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...
