Problems solved by technology

[0010] When the SRNC supports the enhanced feature of uplink layer 2 and the target cell managed by the DRNC does not support the enhanced feature of uplink layer 2, the DRNC will ignore the maximum MAC-d PDU length extension information element after receiving the radio link establishment request message, Parsing the MAC-d PDU length information element, and this MAC-dPDU length information element is empty at this time, so DRNC will not be able to correctly carry out the configuration of layer 2 protocol entity, so return the wireless link establishment failure message to SRNC, thereby cause wireless link establishment failed

Embodiment 1

[0037] Such as image 3 As shown, the request method for wireless link establishment provided by the embodiment of the present invention includes the following steps:

[0038] Step 31. The SRNC receives the target cell capability information sent by the DRNC. The target cell is a cell to establish a radio link with the user terminal, and the target cell capability information may indicate whether the target cell supports uplink layer 2 enhanced features.

[0039] Step 32: The SRNC configures the information element indicating the MAC-d PDU length information in the radio link establishment request according to the capability information of the target cell.

[0040] Step 33, the SRNC sends a wireless link establishment request to the DRNC.

[0041] Corresponding to the method for requesting wireless link establishment provided in this embodiment, an embodiment of the present invention further provides a serving radio network controller.

[0042] Such as Figure 4 As shown, t...

Embodiment 2

[0046] Such as Figure 5 As shown, the method for establishing a wireless link provided by the embodiment of the present invention includes:

[0047] Step 51. The SRNC sends an information exchange request message to the DRNC, requesting the DRNC to return target cell capability information indicating whether the target cell supports uplink layer 2 enhanced features, wherein the target cell is a cell that will establish a radio link with the user terminal.

[0048] Step 52: The DRNC feeds back an information exchange response message to the SRNC, and reports the capability information of the target cell to the SRNC.

[0049] Step 53, the SRNC judges whether the target cell supports the enhanced feature of uplink layer 2 according to the capability information of the target cell.

[0050] If the target cell does not support the enhanced feature of uplink layer 2, proceed to steps 54, 56 and 57; if the target cell supports the enhanced feature of uplink layer 2, proceed to step...

Embodiment 3

[0063] Such as Figure 7 As shown, the method for establishing a wireless link provided by the embodiment of the present invention includes:

[0064] Step 71. The SRNC receives the cell capability information sent by the DRNC, which includes the capability information of the target cell, that is, the capability information of the cell to establish a radio link with the user terminal.

[0065] Step 72, the SRNC judges whether the target cell supports the enhanced feature of uplink layer 2 according to the capability information of the target cell.

[0066] If the target cell does not support the enhanced feature of uplink layer 2, proceed to steps 73, 75 and 76; if the target cell supports the enhanced feature of uplink layer 2, proceed to steps 74, 75 and 76.

[0067] Step 73. When the user terminal is about to establish a radio link with the target cell, the SRNC sends a radio link establishment request to the DRNC. The radio link establishment request includes a MAC-d PDU l...

Abstract

The invention discloses a request method for wireless link set, equipment and a method thereof, relating to the communication technical field, in order to solve the problem of low success ratio of wireless link set under enhancing features of an upgoing layer 2. The method for wireless link set provided in the invention comprises the following steps: a service wireless network controller (SRNC) beforehand learns the ability information of a target cell regimented by a drifting wireless network controller (DRNC); the ability information of the target cell indicates whether the target cell supports the enhancing features of the upgoing layer 2; and SRNC reasonably configures cells expressing MAC-d PDU length information in wireless link set requests according to the ability information of the target cell and starts the wireless link set requests.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for requesting wireless link establishment. Background technique [0002] The process of establishing a radio link is a process of allocating necessary resources for one or more radio links in the Drift Radio Network Sub-system (DRNS) and establishing a connection-oriented signaling bearer at the same time. [0003] The establishment of a wireless link is achieved through the following procedures: [0004] When SRNC (Serving Radio Network Controller, Serving Radio Network Controller) decides to add the first or first batch of cells of a certain DRNS (Drift Radio Network Sub-system, Drift Radio Network Sub-system) to the specified connection active set , it will send a wireless link establishment request message to the corresponding DRNC (DriftRadio Network Controller, Drift Radio Network Controller) to request the establishment of a wireless link. ...
