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, system of selection, system and the equipment of access service grade in particularly a kind of random access procedure.
Background technology
TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, the TD SDMA access) UE (User Equipment in the system, when subscriber equipment) initiating to insert at random, MAC (Medium Access Control, the medium access control) layer by primitive from RRC (RadioResource Control, Radio Resource control) layer receives RACH (Random Access Channel, Random Access Channel)/Control Parameter of E-RUCCH (E-DCH Random Access Uplink Control Channel strengthen dedicated channel insert ascending control channel at random) transmission, promptly
-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
iBe to continue probability;
-maximum number of attempt Mmax synchronously.
Insert E-RUCCH at random with enhancing and be transmitted as example, UE will carry out the ASC selection in the prior art before initiating to strengthen random access procedure, promptly from the Control Parameter of RRC configuration, choose an ASC grade, according to the sequence number of formula (1) selection ASC grade, thus value definite and the corresponding lasting probability of sequence number:
ASC＝min(NumASC，MinMLP) (1)
Wherein, NumASC is the maximum sequence number of ASC grade, at RB (Radio Bear, radio bearer) each logic channel all can be assigned with a priority of logical channels MLP (MACLogical channel Priority in the foundation/reconfiguration course, the scope of MLP is 1～8, the more little priority of value is high more), MinMLP is that UE initiation enhancing has the highest priority of logical channels in the data logic channel to be sent when inserting at random.
When not receiving the response that successfully inserts when a UE physical layer random access procedure of initiation, number of attempt adds 1 synchronously, and UE is according to selected probability P subsequently
iContinue to initiate random access procedure, insert success at random or reach maximum number of attempt Mmax synchronously up to strengthening.
In addition, in traditional C ELL_FACH (cell forward access channel) state, do not give the UE assigned with dedicated channel.UE goes up at descending FACH (Forward Access Channel, forward access channel) and receives low volume data, at up use RACH (Random Access Channel, Random Access Channel) transmission low volume data.Because physical resource that FACH and RACH shone upon has certain limitation, and these two channels all adopt the modulation system of low order, so message transmission rate is lower under this state.The TD-SCDMA system is at 3GPP Rel8 (The 3rd Generation Partership Release 8, third generation affiliate organizes version 8) in introduced enhancing CELL_FACH characteristic, in strengthening the CELL_FACH characteristic, with HSDPA (High speed Downlink Packet Access, high speed downlink packet inserts) and correlated channels and the transmission mechanism of HSUPA (High speed Uplink Packet Access, high speed uplink packet access) be incorporated into the CELL_FACH state.So, strengthen under the 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) and go up transmission.Upstream data is mapped to E-DCH (Enhanced DedicatedChannel, strengthen dedicated channel) on, further be mapped to E-PUCH (E-DCH Physical UplinkChannel, E-DCH physical uplink channel) goes up transmission, can improve the transmission rate of signaling under the CELL_FACH state by such data transfer mode, reduce the signaling propagation delay time.
Strengthen under the CELL-FACH state, the up-downgoing transfer of data realizes by scheduling mode.There is not transfer of data to allow the UE uplink loss after a period of time, downlink data as UE reaches, when NodeB (Node B) expectation recovers scheduling, if the UE uplink loss, NodeB can send earlier and set up order synchronously, just recovers downlink data dispatching after receiving the confirmation of synchronization of UE.UE receives and needs to initiate random access procedure after the synchronous foundation order and finish uplink synchronous, and by the E-RUCCH feedback acknowledgment.The deficiencies in the prior art are: MinMLP has the highest priority of logical channels in the upstream data logic channel to be sent, this moment is not because UE has upstream data etc. to be sent, just there is not corresponding M inMLP yet, if according to the method that ASC in the existing protocol selects, existence can't be selected the problem of ASC grade according to priority of logical channels.
In addition, strengthen under the CELL-FACH state, UE carries out the gravity treatment of normal sub-district, the sub-district gravity treatment is the independent behaviour of UE, NodeB does not also know, when UE satisfies the sub-district reselection conditions, if NodeB is carrying out uplink data scheduling, UE just needs as early as possible gravity treatment indication in sub-district to be sent to NodeB, continues scheduling and the waste resource to avoid NodeB.If the priority of logical channels MinMLP of UE etc. this moment upstream data to be sent is lower, the ASC grade of selecting according to existing protocol may be lower, and gravity treatment indication in sub-district can not in time notify NodeB can cause the interface-free resources waste.
