In the 3GPP wireless access network, radio network controller (RNC) is the core of wireless access network resource management and scheduling at present, and centralized management access network equipment and various resource also concentrate on RNC to the management and the scheduling feature of base station (Node B) resource.Fig. 1 is the schematic diagram of wireless access network resource management framework in the prior art, as shown in Figure 1, the logical O﹠M module of Node B links to each other with the logical O﹠M unit and the business function module of Access Network management resource module among the RNC respectively by Iub interface with business function module, RNC administers and maintains various resources in Node B and the Node B by the logical O﹠M function of this Iub interface, as: the foundation of new sub-district, the parameter configuration of sub-district, the cell channel configuration, the deletion of sub-district, the management of wireless channel and parameter configuration etc.Fig. 2 manages the flow chart of maintenance for wireless access network in the prior art to Node B resource, and in conjunction with Fig. 1, shown in Figure 2, wireless access network to the general step that Node B resource manages maintenance is:

1) RNC comprises that to the equipment of wireless access network the running status of Node B manages and controls, and carries out the administration order that receives from network management center, and monitor network or Node B break down/the fault recovery situation, carries out RRM and optimization.

2) when RNC find to need changes the resource distribution of Node B and resource status, RNC sends the logical O﹠M order by Iub interface to Node B, Node B is managed, as: in Node B, set up new sub-district, the deletion sub-district, revise cell configuration and channel configuration, resource or the like in obstruction or the open Node B.

3) Node B actuating logic Operation and Maintenance function disposes resources such as corresponding sub-district, channel, interface according to the requirement of RNC, and offers RNC control and use.

4) RNC is after the resource that configures Node B, carry out radio resource management function, needs according to connection management and session management, manage and use Node B resource by various control procedures, as Radio Link set up, Radio Link increases, Radio Link discharges, Radio Link reconfigures, NodeB resource inspection etc.

For Node B, it is responsible for the functional entity of transmitting/receiving wireless signal as wireless access network, and following resource mainly is provided:

A.Node B offers the sub-district and corresponding physical channel resources, spreading code code tree of universal mobile telecommunications system grounding wireless access network network (UTRAN), comprise public physical channel resources and special-purpose physical channel resources, as the physical channel in sub-district Cell and the sub-district: DPCH (DPCH), Physical Downlink Shared Channel (PDSCH), Primary Common Control Physical Channel (PCCPCH), Secondary Common Control Physical Channel (SCCPCH), Physical Random Access Channel (PRACH) and physical common grouped channels (PCHCH) etc.;

B.Node B connects the transfer resource of RNC, comprise the interface transmission circuit, be used to set up Node B communication context and transmit the Node B control port of broadcast channel (BCH) information, transmit the dedicated channel (DCH), Random Access Channel (RACH), forward access channel (FACH), CPCH (CPCH), DSCH Downlink Shared Channel (DSCH), Uplink Shared Channel (USCH), paging channel (PCH) port of various data flow etc.

Embodiment

The present invention proposes a kind of new Node B resource management using method, be system resource by Node B management self, details with physics such as all or part of physical channel, coffret or logic system resource offer RNC then, and authorize RNC to use; RNC is in the sorts of systems resource of using Node B to provide within the scope of authority of Node B.Referring to shown in Figure 4, the basic process that Node B resource authorization uses comprises the steps: at least

1) whether the availability of system resources such as physical resource and logical resource change has taken place in the Node B supervisory control system running state, check system.

2) availability in Node B initial launch, system resource changes, the mandate of RNC is changed etc. under the situation that resource allocation or application feature change, Node B issues resource information to RNC, and the details of all kinds of resources in the indication Node B also authorize RNC to use all or part of Node B resource.

3) RNC preserves the resource information that Node B provides, at Node B within the scope of authority, and the resource in control and the use Node B, as: utilize the DPCH of Node B and coffret to set up connecting path from subscriber equipment (UE) to RNC or the like.

Under this management mode, a Node B can support a plurality of RNC, is distributed to a plurality of RNC when Node B can be with the system resource information of same that is:, by a plurality of RNC controls with use.As shown in Figure 5, UE communicates by letter with core net (CN) by Radio Access Network, comprises three base station node B1, Node B2 and Node B3 in wireless access network at least, also has two wireless controller RNC1 and RNC2.So, Node B1 is distributed to RNC1 and RNC2 in the time of can be with the system resource information of same, jointly all kinds of resources that Node B1 is provided is controlled, is managed and use by RNC1 and RNC2, and Node B2 and Node B3 also are like this.

When Node B gives one or more RNC its resource allocation, can adopt the multiple basic method of salary distribution.And, when the resource that is provided at Node B changes, also adopt these allocative decisions to redistribute resource and give RNC:

1) fixed allocation: according to the network planning, distribute adequate resources to use for different RNC by network management center; Node B is handed down to resource allocation information in network management center, is authorized to corresponding RNC by Node B.

2) strategy distributes: the strategy that network management center distributes for Node B down distributing resource, carry out resource allocation according to the priority of RNC or the disposal ability of RNC or the resource situation of RNC or path or other conditions between RNC and the Node B, determine according to resource allocation policy when which resource by which RNC is used by Node B.

3) the comprehensive distribution: network management center distributes to one or several RNC to the part resource of Node B according to the mode of fixed configurations, and other Node B resource is carried out resource allocation by Node B according to the mode of policy configurations.

And for the resource that Node B will distribute, can use by a RNC control, also can control use jointly by a plurality of RNC.These allowable resources comprise physical channel resources in the sub-district, network transmission resource or the like.Therefore, from the angle of RNC, after Node B was to the available resource information in a plurality of RNC issue Node B, RNC can have multiple operational version to Node B resource:

1) resource contention uses: under the identical situation of the Node of each RNC permission to use B resource, during certain resource, must obtain Node B approval in certain RNC need use Node B; When a plurality of RNC apply for using identical resource simultaneously, carry out the scheduling of resource function by Node B, according to the precedence of predefined priority or resource bid, the final right to use of ruling resource.

2) resource is independently used: under the situation that the resource of each RNC permission to use has nothing in common with each other, each RNC uses and controls corresponding resource alone, and the available resources of Node B are set of the resource that can control of these RNC.

3) mix use: under in conjunction with the situation that adopts above dual mode, a plurality of RNC of part resource grant share, by a plurality of RNC competition uses; The part resource only permits to some RNC, used separately and controlled by it.

Because Node B connects one or more RNC simultaneously,, and set up the signaling connection with it so Node B after system's initial start, must seek the RNC adjacent with it with discovery.Node B can find adjacent RNC by following several modes:

1) fixed configurations: network management center is according to the network planning, the address parameter of configuration Node B and and RNC between annexation.Node B can ask for RNC information from relevant RNC after system start-up, and to relevant RNC issue resource information.RNC information can be used as the foundation that Node B Resources allocation is given different RNCs.

2) dynamically find: Node B is after system start-up, by the mode of broadcasting, to contiguous RNC issue Node B resource indication; After RNC receives the resource indication of Node B broadcasting, set up signaling with Node B and is connected also the information of RNC is notified to Node B, inquire about the resource situation of Node B simultaneously; Node B collects the information of adjacent R NC, according to predefined allocation strategy, such as: press RNC priority, press RNC response speed, press resource situation of RNC or the like, to RNC distribution adequate resources.

3) historical configuration: after Node B adopts dynamically discovery or fixed configurations to find adjacent RNC, preserve the connection configuration information of relevant RNC.When Node B when restarting, the RNC that Node B reads in preservation connects configuration information, and utilizes these information to rebulid and being connected of RNC.

After Node B finds adjacent RNC and connects, when issuing resource information, the one or more RNC that connected can adopt broadcast mode to all RNC issue resource informations, and also can be at the directed issue of some or several specific RNC resource informations.Usually, Node B is in both cases to RNC issue resource information: powering on goes into operation or when the resource operating position changes when restarting, in the Node B.

When powering on, Node B goes into operation or when restarting, the issuing process of resource information can have two kinds of implementations in the Node B:

1) directly to RNC issue message related to resources, message inside comprises the resource information that all allow this RNC to use to Node B.

A. broadcast mode: Node B all RNC issue resource informations in network, wherein, message inside has comprised all resource informations of Node B and to the authorization message of each RNC.

B. directed issue: Node B is to the RNC of appointment issue resource information, and message parameter comprises the resource information that this RNC of permission uses, and also can comprise all resource informations of Node B and point out the scope of authority to this RNC.

2) Node B is to the indication of RNC issue resource, and RNC receives the indication back to Node B initiation querying command, and order Node B returns the resource information that all allow this RNC to use.The issue of resource indication also is divided into broadcasting and two kinds of orientations, that is: Node B all RNC in network or the RNC issue resource indication of appointment.

When the resource operating position changed in the Node B, as equipment fault, equipment recovered or the like, need change take place to relevant RNC notice resource behaviour in service.The issuing process of resource modification information can adopt following three kinds of modes:

1) Node B issues up-to-date resource information again to RNC, its again issuing process with noted earlier power on go into operation or when restarting the resource information issuing process identical.

2) Node B sends out resource changing message to RNC, and message inside comprises state the specific resources information that changes has taken place.

A. broadcast mode: Node B all RNC in network issue resource information again, and wherein, message inside has comprised all resource informations of Node B and to the authorization message of each RNC.

B. directed issue: Node B issues resource information again to the RNC of appointment, and message parameter comprises the resource information that this RNC of permission uses, and also can comprise all resource informations of Node B and point out the scope of authority to this RNC.

3) Node B sends out the resource changing indication to RNC, and RNC receives the indication back to Node B initiation querying command, and indication Node B returns relevant resource information.The issue of resource changing indication also is divided into broadcasting and two kinds of orientations, that is: Node B all RNC in network or the RNC issue resource changing indication of appointment.
