Along with development of wireless communication devices, communication network becomes increasingly complex and is huge, therefore the maintainability of network is had higher requirement.In TD-SCDMA and WCDMA mobile communication system, the Operation and Maintenance of mobile communication Node B (Node B) is divided into logical O﹠M and specific operation is safeguarded two parts.Wherein, the logical O﹠M of Node B is to realize by Node B application protocol (NBAP, Node B Adaptation Part), and is corresponding, the logical O﹠M passage of Node B is exactly the signaling bear of NBAP, and clearly regulation has corresponding operation and maintenance method in the 3GPP standard; Realization for the maintenance of Node B specific operation, only stipulated in the 3GPP standard that a Node B is by radio network controller (RNC, Radio Network Controller) the transparent implementation method that is routed to Operation and Maintenance platform (OMC-R, Operations and Maintenances Center-Radio).But, particularly a concrete solution is not proposed for the PVC (PVC, Permanent VirtualCircuit) of Node B and the distribution of Internet Protocol (IP) address at the specific implementation process.
At present, the implementation method of the specific operation of Node B maintenance mainly contains following three kinds:
First method is when all Node B initial start-ups, adopts the default PVC and the IP address that set when dispatching from the factory, initiates request by RNC to OMC-R; Then, obtain formal configuration data from OMC-R; After waiting to restart, PVC that employing formally configures and IP address and OMC-R get in touch, and delete original default PVC and IP address information.Because all Node B is same PVC and the IP address of employing before the configuration that powers on, so all Node B can not walk abreast simultaneously and power on;
Second method is a kind of OM channel creating a mechanism automatically based on Bootstrap Protocol (BOOTP, Bootstrap Protocol).After Node B started, automatically from default PVC, by the request that RNC sets up OM channel to the OMC-R initiation, OMC-R received after the request, gives this Node B distributing IP address automatically, thereby sets up the OM channel between Node B and the RNC.
The third method is on the basis of second method, added the dynamic assignment mechanism of PVC, the assigning process that has kept the IP address simultaneously, but the distribution of its IP address is to have utilized a DHCP (DHCP, Dynamic Host Configuration Protocol) server to realize.
Automatically though the process of setting up of the third method OM channel, can solve the shortcoming of first method under certain condition, still has the following disadvantages:
(1) distribution of PVC and IP address is divided into two independently processes, brings inconvenience for the foundation and the maintenance of Internet Protocol (IPOA, IP Over ATM) passage of the asynchronous transmission mode carrying of RNC, has also increased the flow process expense of Iub interface simultaneously;
(2) IP address assignment of Node B is only limited in the scope of RNC management, does not consider an OMC-R, manages the PVC of all the Node B below a plurality of RNC and the distribution condition of IP address simultaneously, does not therefore have of overall importance.
Summary of the invention

For addressing the above problem, the present invention adopts following technical scheme: the method for this radio network controller dynamic-configuration PVC and IP address, adopt tree-like hierarchical structure to finish, comprise the steps: the PVC of Node B and the distribution and the management of IP address
(1) radio network controller distributes an IP address and a PVC to Node B, and adds the route table items that this IP address and PVC are tied to Node B in the asynchronous transmission mode carrying Internet Protocol table of local maintenance;
(2) radio network controller and Node B are set up asynchronous transmission mode carrying Internet Protocol passage and it are safeguarded.
According to technique scheme, the present invention as a gateway, has carried out the dynamic-configuration of PVC and IP address to the Node B that is managed with RNC, the Iub mouth set up and Node B between the IPOA passage.After passage is set up, gateway RNC realizes the transparent forwarding of the Operation and Maintenance signaling between Node B and the OMC-R, simultaneously the IPOA passage is safeguarded, when detecting the IPOA channel status when unusual, this passage be can discharge, and PVC and IP address assignment and the passage foundation of Node B carried out again.Realized that Node B goes into operation automatically and set up and safeguard the IPOA passage, and can effectively prevent the conflicting problem of PVC or IP address.
