Description
Technical field
The present invention relates to the communications field, particularly, relate to the E-RNTI collocation method and the system of the subscriber equipment of uplink reinforced CELL-FACH (Cell Forward Access Channel, cell forward access channel) state.
Background technology
Along with the evolution of GSM, the QoS that improves the user has become one of primary goal of operator, and this is because QoS has influenced service performance, has also just determined the satisfaction of user to business.The major issue that raising user's QoS need be considered is exactly the time delay when connecting with channel allocation; Simultaneously; Owing to also there is business frequent relatively, that packet is less; Therefore need to consider how to make common signal channel work more effective, such as, the signaling delay of up link and down link can be reduced.
For CELL_FACH (Cell Forward Access Channel; Cell forward access channel), CELL_PCH (Cell Paging Channel; The cell paging channel), the downlink signaling of URA_PCH (UTRAN Registration Area Paging Channel, UTRAN registration area PCH) state postpones 3GPP (3rd Generationpartnership project; The third generation mobile partnership projects) standard is to insert (High Speed Downlink Packet Access through introducing high speed downlink packet; Abbreviate HSDPA as) realize, and, also be in research and talking stage at present for the delay issue of up signaling.
In the process of embodiment of the present invention, the inventor finds that up letter is modern to postpone in order to reduce, and needs to consider following several aspects:
(1) reduces IDLE mode (idle pulley), CELL_FACH, CELL_PCH and the user plane of URA_PCH state and the stand-by period of chain of command;
(2) peak rate of increase CELL_FACH state;
(3) reduce the transition delay of CELL_FACH, CELL_PCH, URA_PCH state and CELL_DCH (Cell Dedicated Channel, cell private channel) state.
To achieve these goals; Can introduce at the CELL_FACH state uses high speed uplink packet to insert (High Speed Uplink Packet Access; Abbreviate HSUPA as) mode; In this article, the CELL_FACH state is used high-speed uplink packet access technique, be called the uplink reinforced CELL-FACH technology.
For high-speed uplink packet access technique; Its authorization is that Node B is passed through the authorization message that on E-AGCH (E-DCH Access Grant Channel, E-DCH insertion authority channel) or E-RGCH (E-DCH Relative Grant Channel, E-DCH relative authorization channel) channel, obtains being correlated with; Subscriber equipment (User Equipment then; Abbreviate UE as) according to authorization message, determine its operable transmitting power, thus the data volume that decision can be sent.And E-AGCH, E-RGCH are through main E-RNTI (E-DCHRadio Network Temporary Identifier; Strengthen the Radio Network Temporary Identifier of dedicated channel) or assist E-RNTI and inform that as CRC (Cyclic Redundancy Code, cyclic redundancy code) mask whether its loaded information of subscriber equipment is with own relevant.
For the uplink reinforced CELL-FACH technology; It is actually the user for the CELL_FACH state; Its up High Speed Packet Access that also adopts; UE also must confirm whether the information of sending on E-AGCH or the E-RGCH channel is with own relevant, for UE, is the E-RNTI that is distributed to oneself by Node B through the downstream feedback channel notification of uplink reinforced CELL-FACH through E-RNTI so.And for the user of CELL_DCH state, it also is to obtain authorization message through monitoring E-AGCH/E-RGCH.
Therefore; Produce when the authorization message of receiving node B for fear of the UE of CELL_DCH state and CELL_FACH state and to obscure; Need Node B when giving the UE configuration E-RNTI of CELL_FACH state; Consider the E-RNTI configuration of the UE of CELL_DCH state; And the configuration of the E-RNTI of the UE of CELL_DCH state is by radio network controller configuration, so iff comes the employed E-RNTI of UE of Control Allocation CELL_FACH state by Node B, then can not avoid the identical situation generation of E-RNTI of CELL_DCH state and the UE of CELL_FACH state.
At present, also there is not effectively solution of the above problems.
