Description
Technical field
The present invention relates to wireless communication field, relate in particular to terminal positional information sending method, terminal resource distribution method and device thereof.
Background technology
Along with the development of 3G (Third Generation) Moblie technology, it is separated with radio frequency that the method for designing of base station trends towards base band, and baseband extension type base station is exactly the base band base station separated with radio frequency.Baseband extension type base station adopts a plurality of spaced antenna groups, realizes and covering.For each specific antenna sets, cover, can be defined as a cellportion (，Huo Kecheng cell portion district, subspace, community), by cell portion ID, identified.Radio network controller (Radio Network Controller, RNC) need to know terminal (UserEquipment, UE) be positioned at which cell portion, like this can be according to corresponding RRM (Radio Resource Management, RRM) strategy, determine the Initial Trans of UE, and distribute concrete frequency, time slot and code resource.In addition, along with the movement of UE at the different areas of coverage, RNC also needs to understand in real time the change in location of UE, thereby can effectively carry out dynamic channel allocation (DCA, Dynamic Channel Assignment), improves throughput and the resource utilization of system.
In prior art, RNC can obtain the positional information of UE by 2 kinds of modes, and which cell portion UE is positioned at:
A kind of mode is that UE is when initially access, by UL FP (the Up Link FrameProtocol of user's face, up connection Frame Protocol) frame is known, as, the residing cell portion of UE information reporting can be carried to RNC, specifically as depicted in figs. 1 and 2 by RACH FP frame or E-DCHFP frame in base station.Fig. 1 shows RACH FP frame format, and wherein, for 1.28Mcps TDD (time division duplex) system, whether the Bit 3 of New IE Flags is used to refer to Cell Portion LCR IE and exists, and 1 represents to exist, and 0 represents not exist; Fig. 2 shows E-DCH FP frame format, and wherein, for 1.28Mcps TDD system, whether the Bit 0 indication Cell Portion LCR ID IE in New IE Flags exists, and 1 represents to exist, and 0 represents not exist.
Another kind of mode reports by base station special measurement after being terminal access.After terminal access, RNC can initiate to measure the base station special measurement that type is Best Cell Portions, require the cell portion of base station report of user ownership, and support periodic report (Periodic), report immediately (On Demand) and change to report (On Modification) three kinds to report mode.
By above two kinds of modes, positional information when RNC can obtain UE and initially accesses, and positional information that can real-time update UE.
Inventor, in realizing process of the present invention, finds that prior art at least exists following defect:
When UE moves between RNC, now for UE, Serving RNC changes.In prior art, source RNC (source RNC) can pass to the relevant UE information of target RNC (Target RNC) by RELOCATION REQUIRED (re-positioning request) message, but for TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, TD SDMA access) intrasystem repositioning process, target RNC cannot know UE accesses under which cell portion of target RNC, thus also just cannot be for UE in Target cell with reference to the suitable Radio Resource of cell portion information distribution.

Embodiment
The problem existing for prior art, the embodiment of the present invention has proposed a kind of terminal positional information delivery plan, and the terminal resource allocative decision based on this scheme.The technical scheme that adopts the embodiment of the present invention to provide, can be in UE repositioning process, make Target RNC can obtain UE in the cellportion of Target cell information, and then to make Target RNC can be the Radio Resource that terminal distribution is suitable in Target cell with reference to this information.The technical scheme that the embodiment of the present invention provides can be embodied as method flow and relevant apparatus.
The adjacent cell relation information that the embodiment of the present invention is used can further improve and obtain on the basis of existing adjacent cell relation information configuration, when the adjacent information of adjacent cells in configuration Yu Yige community, increase the target cell portion information (being the cell portion of UE initial access in Target cell) of this adjacent cell, for example:
Below in conjunction with the accompanying drawing in the present invention, the technical scheme in the present invention is carried out to clear, complete description, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belongs to the scope of protection of the invention.
Referring to Fig. 3, the terminal positional information providing for the embodiment of the present invention sends and the schematic diagram of the flow process that terminal resource distributes.In this flow process, UE is switched to the community 2 of RNC2 (Target RNC) from the community 1 of RNC1 (source RNC), community 1 and community 2 comprise for the neighboring BS relationship of adjacent cell ，Qie community 1: the target cell portion ID of and community 2 adjacent with community 2, community 1.This flow process can comprise step:
The RNC1 of step 301, this UE, according to the adjacent cell relation information of community 1, obtains the cell portion ID of the Target cell (being community 2) of this UE.
In this step, according to current mechanism, when UE is from the handoff procedure of the community 2 of community 1 to the RNC2 administration of source RNC administration, RNC1 can learn the Target cell of UE, further, in the neighboring BS relationship due to community 1, comprising community 1 is adjacent cells with community 2, also comprises the target cellportion ID (being the sign of UE cell portion of initial access while being switched to community 2) of community 2, therefore, RNC1 can get the target cell portion ID of the Target cell of this UE.
In this step, for TD-SCDMA system, RELOCATION REQUEST message can comprise following content:
Source ID, i.e. source RNC sign;
Target ID, i.e. Target RNC sign;
Source To Target Transparent Container, source is to target transparent vessel, and this container can comprise:
Relocation Type IE, it is reorientation type, UE involved in relocation of SRNS or UE not involVed in relocation of SRNS, be that source RNC determines whether this reorientation can relate to UE, if it is use UE involved in relocation of SRNS, otherwise use UE notinvolved in relocation of SRNS;
Number of Iu Instances IE, the i.e. current Iu signaling linking number having existed of UE;
