Description
Technical field
The present invention relates to a kind of configuring management method of local cell resource, relate in particular to the configuring management method of local cell resource in a kind of 3-G (Generation Three mobile communication system).
Background technology
The development of world's mobile communication technology is behind the digital mobile phone that has experienced first generation simulation standard mobile phone and second generation gsm system, along with demand to data services such as multimedia function and high-speed radio Internet accesses, original second generation gsm system that only has transmission sound and low speed data transfer function can not meet the demands, has produced 3-G (Generation Three mobile communication system) in being based on the CDMA multi-access mode.
As shown in Figure 1, with the WCDMA system is example, mainly by core net (Core Network, CN), land radio access web (UMTS Terrestorial Radio Access Network, URTAN) and user's set (User Equipment is hereinafter to be referred as UE) three parts form.The interface definition of CN and UTRAN is the Iu interface, and the interface definition of UTRAN and UE is the Uu interface.
As shown in Figure 2, UTRAN comprises many RNS (RadioNetwork Subsystem, RNS) that are connected to CN by the Iu interface.A RNS comprises a RNC (RadioNetwork Controller, radio network controller) and one or more Node B (Node B).NodeB is connected on the RNC by Iub interface, comprises one or more sub-districts among the Node B.
RNC and Node B finish the allocation manager of sub-district and relevant common signal channel and dedicated channel resource jointly by the Iub interface of standard.
As shown in Figure 3, set up the process schematic diagram for the sub-district.At first send the sub-district by RNC to Node B and set up request message, response message is set up by Node B response sub-district in the success back.This process is used for setting up a sub-district at Node B.RNC will be come into operation by the sub-district of C-ID sign, and the resource that is identified by Local Cell ID among the Node B is used in this sub-district.
As shown in Figure 4, for Node B the resource status Indication message is sent to the process schematic diagram of RNC.When a home cell becomes in Node B when existing, by this process, this home cell of Node B notice RNC can be used; A home cell in Node B is deleted, promptly becomes when not existing, and by this process, the deletion of Node B notice RNC home cell is by this sub-district among the RNC use sub-district delete procedure deletion Node B.
As shown in Figure 5, the process of deleting for the sub-district.At first send the sub-district deletion request message to Node B, after the success, by Node B response sub-district deletion response message by RNC.This process is used for deleting the sub-district of Node B.Node B discharges the resource by Local Cell ID sign.
Do not have the management method of clear and definite Node B side sub-district in the existing standard, in the prior art, RNC side configuration personnel pass through O﹠amp; M (Operation and Maintenance, Operation and Maintenance) system is configured the sub-district of C-ID sign, comprises the information of the Local Cell ID of this sub-district correspondence.Node B side configuration personnel pass through O﹠amp; M is configured the home cell of Local Cell ID sign, and the Local Cell ID of the configuration of the sub-district of these sign needs and RNC side C-ID sign is consistent.
Finish the static allocation and the management of local cell resource by the correct corresponding relation of C-ID and Local Cell ID.Node B receives when request is set up in the sub-district, check whether the Local Cell id information unit in the message exists corresponding home cell configuration, if exist, Node B will keep necessary resource and according to the parameter that provides in the message new sub-district will be configured.
And, can be divided into two kinds of situations for the deletion sub-district:
From the sub-district deletion that RNC initiates, this situation is the Iub agreement flow process of standard, as shown in Figure 5.Under this situation, Node B has discharged the resource by Local Cell ID sign, but Node B side data storehouse also keeps the configuration information of home cell, needs the configuration personnel to pass through O﹠amp; The information of this home cell of the manual deletion of M.
O﹠amp from Node B side; The home cell deletion that M initiates in the Iub agreement, does not have the flow process of the deletion sub-district that Node B initiatively initiates, therefore for O﹠amp; The deletion home cell operation that M initiates is reflected in the resource status indication the most at last, reports RNC by Node B, initiates sub-district deletion flow process by RNC then.In this process, O﹠amp; The deletion flow processing imperfection of the misoperation of M or Node B side with regard to causing the inconsistent situation of cell information of RNC side and Node B side easily, increases managerial complexity.
Yet, in the technology of existing home cell management, can produce following point:
At first, the correctness of C-ID and Local Cell ID corresponding relation is by O﹠amp; The M personnel guarantee that in configuration under the situation of configuration error, failure is set up in the sub-district, can cause the waste of resource allocation, and increase the wrong workload of investigation.
Secondly, existing technology is carried out static allocation manager for local cell resource, the flexibility shortcoming, and the utilization of resources occurs unbalanced easily.Increase or delete a sub-district in the RNC side, need also carry out corresponding O﹠amp in the NodeB side; The M configuration.
Once more, Node B and RNC cause the inconsistent of both sides resource information configuration easily to the dual command of sub-district, give O﹠amp; M brings extra complexity.
At last, in a UTRAN, the number of Node B can be very many, and each home cell is all needed to carry out manual configuration, O﹠amp; The workload of M is huge, inefficiency.
