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
The present invention relates to the communications field, relate in particular to requesting method, equipment and system that a kind of Radio Link is set up.
Background technology
The process that Radio Link is set up is that (Drift Radio NetworkSub-system is the necessary resource of one or more wireless link distribution in DRNS), sets up the process of connection-oriented signaling bear simultaneously at the drifting radio network subsystem.
The foundation of Radio Link realizes through following flow process:
As SRNC (Serving Radio Network Controller; Service wireless network controller) decision is with certain DRNS (Drift Radio Network Sub-system; When first or first sub-district drifting radio network subsystem) is added in the connection Active Set of appointment; It will send Radio Link to corresponding D RNC (DriftRadio Network Controller, floating radio network controller) and set up request message, sets up Radio Link with request.
As shown in Figure 1, DRNC is the resource of this Radio Link application of each wireless link distribution after receiving that above-mentioned Radio Link is set up request message.After all Radio Links were successfully set up, DRNC sent Radio Link to SRNC and sets up response message.As shown in Figure 2, if DRNC can not successfully set up wherein one or more Radio Link, DRNC returns Radio Link to SRNC and sets up failed message so, indicates failure cause in the message.
At present, in setting up the process of Radio Link, that carry out the transmitting uplink data employing all is the MAC-d PDU (Medium Access Control-d Protocol Data Unit, MAC-d protocol Data Unit) of regular length.
The R8 version of 3GPP agreement has been introduced uplink layer 2 and has been strengthened these new features.In order more reasonably to dispose MAC (Medium Access Control, medium access control) layer entity parameter, set up the MAC-d PDU that has adopted variable-length based on the Radio Link of uplink layer 2 enhanced characteristic.
Strengthen under this characteristic in uplink layer 2; When SRNC when DRNC sends Radio Link and sets up request message; This Radio Link is set up and is comprised the maximum MAC-d PDU extended length cell that is used to represent variable MAC-d PDU length in the request message simultaneously, and is used to explain the fixedly MAC-dPDU length cell of MAC-d PDU length.DRNC receives this Radio Link and sets up request message; If DRNC detects this Radio Link and sets up and comprise maximum MAC-d PDU extended length cell in the request message, then DRNC will ignore this Radio Link and sets up the MAC-d PDU length cell that comprises in the request message.
State in realization in the process that Radio Link is set up under uplink layer 2 enhanced characteristic, the inventor finds to exist at least in the prior art following problem:
Support uplink layer 2 enhanced characteristic and the Target cell of DRNC administration is not supported under the situation of uplink layer 2 enhanced characteristic at SRNC; DRNC receives and can neglect maximum MAC-d PDU extended length cell wherein after Radio Link is set up request message; Resolve MAC-d PDU length cell; And this moment, this MAC-dPDU length cell was empty; DRNC can't correctly carry out the configuration of layer two protocol entity like this, set up failed message so return Radio Link to SRNC, thereby cause Radio Link to set up failure.
