Description
Technical field
The present invention relates to RRM, be specifically related to the enhancing-exclusive use transmission signal channel resource allocation method under a kind of cell forward access channel CELL_FACH state.
Background technology
3G (Third Generation) Moblie partnership 3GPP carries out the standardization effort of the up enhancing of CELL_FACH state at present.The up enhancing of CELL_FACH makes it obtain less packet transfer delay and higher transmission rate by introducing the ascending packet data transmission performance that the E-DCH transmission channel strengthens this state at the CELL_FACH state.
In the version before 3GPP Rel-7, the E-DCH transmission is only used under CELL _ DCH CELL_DCH state, signaling on Dedicated Control Channel DCCH or the Dedicated Traffic Channel DTCH logic channel or data map are mapped on enhancing-physical uplink channel E-PUCH physical channel to the E-DCH transmission channel again.The E-DCH business is divided into dispatching services and non-scheduling service by the difference of scheduling mode, and wherein the resource of non-scheduling service is that terminal UE is distributed by radio network controller (RNC), and resource has periodically and specificity, is suitable for real time business.In dispatching services, be that node Node B (base station) distributes sub-district enhanced uplink resource pool by service radio network controller SRNC, be single UE Resources allocation by Node B.
When the E-DCH channel is introduced the CELL_FACH state, need to consider the characteristics of this state self.At the CELL_FACH state, UE uses the public resource in the sub-district, and air interface (hereinafter to be referred as the Uu mouth) is not set up the dedicated link of UE, thereby non-scheduling service can't be incorporated into the CELL_FACH state, and the CELL_FACH state can only carry out dispatching services.Under the CELL_FACH state, Iub interface (protocol interface between RNC and the Node B) is for UE sets up dedicated transmissions, thereby do not have the specific configuration information of UE among the NodeB, and this will attract a series of E-DCH resource allocation problems.
At first can have a look the transfer process of dispatching services under the CELL_DCH state, see Fig. 1.
101:SRNC can be for this UE sets up enhanced uplink through admitting control to think, by the Radio Link of NBAP agreement set up or wireless links reconfiguration course to require Node B be that UE sets up the E-PUCH Radio Link;
102: Node B receives configuration parameter, and from the up common pool of the enhancing of this sub-district, distribute control channel for this UE, comprise enhancing-absolute grant channel E-AGCH and enhancing-high speed indicating channel E-HICH, and enhancing-Radio Link temporary mark E-RNTI, the Radio Link by NBAP sets up response or the radio link reconfiguration response returns to SRNC;
103:SRNC initiates radio bearer by the RRC agreement to UE and sets up order, and configuration parameter comprises that table 1 is described every:
E-DCH configuration parameter under the table 1 CELL_DCH state
104:UE receives configuration parameter, replys response message to network side; Determine that according to configuration parameter current E-DCH transport service is available; Data volume becomes at non-0 o'clock by 0 in the logic channel buffering area of UE E-DCH correspondence, and UE initiation E-RUCCH random access procedure inserts at random and comprises the 105-107 step:
105:UE selects to be exclusively used in the uplink synchronous code SYNC_UL that E-DCH inserts at random, sends by ascending pilot channel UpPCH channel;
After 106:Node B detects the uplink synchronous code of UE, send affirmation by the FPACH channel;
107:UE selects a suitable E-RUCCH channel to send dispatch request, wherein carries the E-RNTI information of oneself;
108: after Node B detects the request of access at random of this UE, UE is added among the competition UE group who uses the E-DCH resource, according to the QOS attribute of current resource situation, UE, UE auxiliary dispatching information etc. this UE is dispatched, after distributing adequate resources, send authorization message by the E-AGCH channel to UE, the E-RNTI information that comprises UE in the CRC of E-AGCH (Cycle Redundance Check, the cyclic redundancy check (CRC)) field;
After 109:UE detected the E-AGCH that points to oneself, UE selected suitable transport block length, modulation system according to authorization resources, and behind timing nE-AGCH, UE sends data on the E-PUCH that authorizes;
110: Node B is partly decoded to the E-PUCH channel data, and returns ACK/NACK information on the E-HICH channel.
When carrying out the E-DCH dispatching services under the CELL_FACH state, there is not private processes in the Iub mouth, does not promptly have 101 among Fig. 1,102 flow processs, thereby the relevant resource of E-DCH, as the physical resource configuration, can only be the UE configuration by system broadcast message, but:
1. for private resource, as E-RNTI, by Node B management, Node B for UE distributes, brings UE by RNC in flow process 102 at present.Under the CELL_FACH state,, can't distribute E-RNTI owing to there are not 102 flow processs;
2. relevant with type of service configuration item as E-TFCS, need can't dispose by system broadcast message based on the type of service configuration of UE.RNC can be the parameters relevant with type of service such as UE configuration E-TFCS by dedicated signaling, but also has the conforming problem that how to keep configuration parameter between UE and Node B.This be because, UE need utilize the information relevant with type of service such as E-TFCS to carry out the selection of transport block length, Node B will decode to the E-PUCH channel of UE according to same parameter, thereby these parameters need be consistent between UE and Node B, but owing to lack Iub mouth private processes, Node B can't obtain these parameters.
