Example Embodiment

[0060] The following describes the first embodiment:

[0061] In the first embodiment, through the foregoing steps 103 and 104, the Node B actively reports whether it has a data retention function to the SRNC, so that the SRNC decides whether it is necessary to include the MAC-hs entity reset indication in the transmission to the UE in step 107. In the RRC information. In cell handover, DRNC only functions as a data relay, and does not always exist, nor is it responsible for data transmission. Only SRNC is connected to the core network (CN), so the data always comes from SRNC. Therefore, in this embodiment, the process of establishing a wireless link is simplified, mainly to simplify the DRNC-related operations, and uniformly use the RNC for explanation.

[0062] Such as figure 2 As shown, the first embodiment includes:

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

[0064] Step 202: Node B returns a radio link establishment response to RNC, which...

Example Embodiment

[0073] The second embodiment is described below:

[0074] In addition to the Node B described in the first embodiment actively informing the RNC whether it supports MAC-hs entity data retention by establishing a radio link response, it can also be implemented by the RNC actively asking the Node B. In this implementation manner, no changes are required to the existing process of establishing a wireless link.

[0075] See image 3 As shown, the second embodiment includes:

[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 radio link establishment request to Node B;

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

[0080] If the Node B supports the MAC-hs entity data retention function, step 305, step 306, and step 307 are executed; ot...

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...
