Description
Technical field
The present invention relates to the mobile communication technology field, be specifically related to a kind of method that disposes multi-frequency-point community high speed downlink packet access procedure physical resource.
Background technology
UTRAN (wireless access network) is the wireless access mesh portions in the 3G (Third Generation) Moblie network, its structure as shown in Figure 1:
UTRAN is made up of one group of RNS (RNS), links to each other with CN (core net) by the Iu interface.Each RNS comprises a RNC (radio network controller) and one or more NodeB (base station), communicates by Iub interface between NodeB and the RNC.Communicate by the Iur interface between the RNS.
When UE (subscriber equipment) inserts UTRAN, provide service for it by SRNS (SRNS Serving Radio Network Subsystem); When UE is in mobile status, may need to insert new RNS, i.e. DRNS (drifting radio network subsystem), this moment, UE can be operated under SRNS and the DRNS simultaneously.
HSDPA (high speed downlink packet access) be 3GPP (third generation partner program) in the R5 agreement on satisfying/a kind of new technology that the asymmetric demand of downstream data traffic proposes.It has solved the contradiction between system's covering and the capacity well, has promoted power system capacity greatly, has satisfied user's high speed business demand.
In existing HSDPA scheme, CRNC (controller of control wireless network) is by the Physical Shared Channel reconfiguration course on the Iub interface, in the sub-district of Node B, set up the relevant physical channel of HSDPA, i.e. HS-PDSCH (high-speed physical downlink shared channel (HS-PDSCH)), HS-SCCH (High-Speed Shared Control Channel) and HS-SICH (high-speed shared indication channel).When UE need use the HSDPA function, it was this UE configuration HS-DSCH (high speed descending sharing channel) resource in Node B that CRNC can set up process or wireless links reconfiguration course by the Radio Link on the Iub interface; Node B finishes the relevant resource distribution of HS-DSCH according to the indication of CRNC, selects 1 to 4 couple of HS-SCCH and HS-SICH simultaneously in user's HSDPA Serving cell, and the channel information of selecting is notified to CRNC.
If UE has inserted a plurality of RNS at this moment, and the HS-DSCH related resource is to be configured among the DRNS, and SRNS must just can obtain the HS-DSCH resource distribution that UE uses by the Iur interface message so.DRNC sets up successful response message, the ready message of radio link reconfiguration and radio link reconfiguration response message by the Radio Link on the Iur interface HS-SCCH and the HS-SICH information of UE is sent to SRNC, in message the HS-PDSCH time interval resource is reported SRNC simultaneously; When DRNC reshuffled the HS-PDSCH resource, if variation has taken place the HS-PDSCH gap information, DRNC reported SRNC by the physical channel reconfiguration request message on the Iur interface with new HS-PDSCH time interval resource so.
In the initial related specifications, each Node B is defined in a sub-district and only supports a frequency, and the HSDPA technology also only is applied to the single-frequency dot system.Yet, can not satisfy growing mobile communication requirement because the telephone traffic that single frequency point can be supported is limited.For this reason, introduced the notion of multicarrier, promptly a plurality of frequencies are all supported in each sub-district under Node B, so just can improve the capacity of system widely.
Yet, because present Iur interface and Iub interface scheme are only at the single-frequency dot system, when the Physical Shared Channel reconfiguration request message of Iub interface and the physical channel reconfiguration request message of Iur interface are the physical resource of HSDPA related physical channel allocation Node B, only specified the information of time slot and code channel, and do not specify the information of frequency, that is to say that these two message can only be used for single-frequency point sub-district.Like this, the sub-district for supporting multifrequency point will make Node B or SRNC can't know corresponding resource is positioned on which frequency of this sub-district; Equally, in the response message of Iub interface and Iur interface wireless link establishment process and wireless links reconfiguration course, do not have the information of frequency yet,, can not uniquely determine physical channel, can't support the HSDPA technology for the sub-district of supporting multifrequency point.
Summary of the invention
The purpose of this invention is to provide a kind of method that disposes multi-frequency-point community high speed downlink packet access procedure physical resource, to overcome in the prior art since Iur interface scheme and Iub interface scheme only at the single-frequency dot system, can't satisfy the shortcoming of a plurality of carrier frequency resource configuration needs, improve the transmission of Iur interface and Iub interface information needed in multi-frequency-point community, make multi-frequency-point community support the HSDPA function, improve the entire system performance.
