Abstract
The invention discloses ASC (Access Service Class) selecting method, system and equipment. The method comprises the following steps that UE (User Equipment) initiates a random access process; and when no uplink data waists for sending, the user equipment carries out ASC selection according to the highest priority of all configured uplink logic channels or carries out ASC selection according to a method for specially setting ASC. The invention solves the problems that the UE cannot select ASC according to the priority of the logic channels when sending synchronous confirmation under a state that the traditional TD-SCEMA system strengthens CELL-FACH (Forward Access Channel) and the UE cannot notify a sent cell reselection indication to NodeB in time because the selected ASC is lower. The method can also be used for other conditions that the ASC selected according to MinMLP (Min MAC Logical channel Propriety) is lower than the ASC selected with the method disclosed in the invention.
Description
Technical field
The present invention relates to wireless communication field, particularly system of selection, system and the equipment of access service grade in a kind of random access procedure.
Background technology
TD-SCDMA(Time Division-Synchronous Code Division Multiple Access, TD SDMA access) UE(User Equipment in system, while subscriber equipment) initiating random access, MAC(Medium Access Control, media access control) layer by primitive from RRC(Radio Resource Control, Radio Resource is controlled) layer reception RACH(Random Access Channel, Random Access Channel)/E-RUCCH(E-DCH Random Access Uplink Control Channel strengthens dedicated channel and accesses at random ascending control channel) the control parameter of transmission,
-access service grade (ASC) parameter sets, each ASC grade comprises parameter (i, P
i), wherein, the span of sequence number i be (i=0 ..., NumASC), NumASC is the maximum sequence number (NumASC≤7) of ASC grade, parameter P
ito continue probability;
-maximum synchronous number of attempt Mmax.
To strengthen random access E-RUCCH, be transmitted as example, in prior art, UE will carry out ASC selection before initiating to strengthen random access procedure, from the control parameter of RRC configuration, choose an ASC grade, according to formula (1), select the sequence number of ASC grade, thereby determine the value of the lasting probability corresponding with sequence number:
ASC=min(NumASC,MinMLP) （1）
Wherein, NumASC is the maximum sequence number of ASC grade, at RB(Radio Bear, radio bearer) in foundation/reconfiguration course, each logic channel can be assigned with a priority of logical channels MLP(MAC Logical channel Priority, the scope of MLP is 1～8, the less priority of value is higher), MinMLP has the highest priority of logical channels in data logic channel to be sent while being the random access of UE initiation enhancing.
While not receiving the response of successfully access when a UE physical layer random access procedure of initiation, synchronous number of attempt adds 1, and UE is according to selected probability P subsequently
icontinue initiating random access procedure, until strengthen random access success or reach maximum synchronous number of attempt Mmax.
In addition, traditional C ELL_FACH(cell forward access channel), in state, give UE assigned with dedicated channel.UE is at descending FACH(Forward Access Channel, forward access channel) the upper low volume data that receives, in up use RACH(Random Access Channel, Random Access Channel) transmission low volume data.The physical resource shining upon due to FACH and RACH has certain limitation, and these two channels all adopt the modulation system of low order, so message transmission rate is lower under this state.TD-SCDMA system is at 3GPP Re18(The3rd Generation Partership Release8, third generation partnership version 8) in, introduced enhancing CELL_FACH characteristic, in strengthening CELL_FACH characteristic, by HSDPA(High speed Downlink Packet Access, high speed downlink packet access) and HSUPA(High speed Uplink Packet Access, high speed uplink packet accesses) correlated channels and transmission mechanism be incorporated into CELL_FACH state.So, strengthen under CELL_FACH state, downlink data is mapped to HS-DSCH(High Speed Downlink Share Channel, high speed descending sharing channel) on, further be mapped to HS-PDSCH(High speed Downlink Physical Share Channel, high-speed downstream physical channel shared channel) upper transmission.Upstream data is mapped to E-DCH(Enhanced Dedicated Channel, strengthen dedicated channel) on, further be mapped to E-PUCH(E-DCH Physical Uplink Channel, E-DCH physical uplink channel) upper transmission, by such data transfer mode, can improve the transmission rate of signaling under CELL_FACH state, reduce signalling time delay.
Strengthen under CELL-FACH state, up-downgoing transfer of data realizes by scheduling mode.Do not having transfer of data after a period of time, to allow UE uplink loss, when there being the downlink data of UE to reach, NodeB(Node B) during expectation restoration schedule, if UE uplink loss, NodeB can first send synchronous foundation order, just recovers downlink data dispatching after receiving the confirmation of synchronization of UE.UE needs initiating random access procedure to complete uplink synchronous after receiving synchronous foundation order, and by E-RUCCH feedback acknowledgment.The deficiencies in the prior art are: MinMLP has the highest priority of logical channels in upstream data logic channel to be sent, now because UE does not have upstream data etc. to be sent, just there is no corresponding MinMLP yet, if the method for selecting according to ASC in existing protocol, existence cannot be selected according to priority of logical channels the problem of ASC grade.
In addition, strengthen under CELL-FACH state, UE carries out normal cell reselection, cell reselection is the independent behaviour of UE, NodeB does not also know, when UE meets cell reselection condition, if NodeB is carrying out uplink data scheduling, UE just need to send to NodeB by cell reselection indication as early as possible, to avoid NodeB to continue scheduling and waste resource.If now the priority of logical channels MinMLP of the upstream data to be sent such as UE is lower, the ASC grade of selecting according to existing protocol may be lower, and cell reselection indication can not notify NodeB can cause interface-free resources waste in time.
