Description

UE capability sending method, transfer method and system, and radio network controller

technical field

The present invention relates to a wireless communication system, in particular to a UE capability sending method, transfer method and system, and a radio network controller.

Background technique

The 3rd Generation Partnership Project (The3rdGenerationPartnershipProject, referred to as 3GPP) discusses and analyzes that when the terminal (UserEquipment, UE) supports the application of HS-DSCH (HighSpeedDownlinkSharedChannel, high-speed Downlink shared channel) to transmit data, you need to support: monitor different HS-SCCH (High Speed-Shared Control Channel, high-speed shared control channel) channels in continuous transmission time interval (Transmission Time Interval, TTI for short). In the specific communication process, the RNC (RadioNetworkController, radio network controller) can obtain whether the UE supports the application of the HS-DSCH channel to transmit data under the CELL-FACH through the RRC (RadioResourceControl, radio resource control) connection request message sent by the UE and whether Support monitoring different HS-SCCH channels at continuous transmission time intervals, so as to configure the UE to enter the CELL-FACH state and related parameters of the HS-DSCH channel. At the same time, the NodeB (Node B) also needs to obtain information about the functions supported by the above-mentioned UE, and reserve radio resources matching the capabilities of the UE to meet the needs of actual data transmission.

The Iub/IurFP (FrameProtocol, Frame Protocol) layer belongs to the layer of the user plane protocol, in which the Iub common transmission channel user plane protocol defines the control radio network controller (ControlRadioNetworkController, referred to as CRNC) and the frame of the public transmission channel between NodeB Structure and transmission process; the Iur public transmission channel user plane protocol defines the frame structure and transmission process of the public transmission channel between radio network controllers (RadioNetworkController, RNC for short), and is divided into different data frame structures and transmission processes according to the public transmission channel. transfer process. Among them, HS-DSCHDATAFRAMETYPE2 (HS-DSCH data frame type 2) is used to carry information that needs to be transmitted on the Iur/Iurb interface during HS-DSCH data transmission. The applicable conditions are: the UE is in the CELL-FACH state, and the MAC- dPDUsize (MediumAccessControl-dedicatedchannelProtocolDataUnit, dedicated media access control channel protocol data unit size) is variable (ie flexibleMAC-dPDUSize) and supports enhanced CELL-FACH (EnhancedCell-Fach).

According to the processing flow of the current protocol, in the scenario where the HS-DSCH channel is applied in the CELL-FACH state, the HS-DSCHDATAFRAMETYPE2 frame cannot carry information about whether the UE supports monitoring different HS-SCCH channels at continuous transmission time intervals, that is, the node B cannot obtain information about the capability of the UE, resulting in the inability of Node B to reserve radio resources matching the capability and apply a data transmission mode matching the capability for the UE, resulting in the problem that the actual data transmission process cannot be carried out normally.
