Problems solved by technology

However, in this method, since all NodeBs use fixed IP addresses, the NodeBs cannot be started in parallel at the same time, and the operation and maintenance and network management during the start-up period are relatively complicated.
[0006] It can be seen that the existing method for establishing an operation and maintenance channel lacks an automatic establishment mechanism for the operation and maintenance channel, and the operation is complicated, the workload is heavy, and errors are prone to occur, which makes the maintenance cost of the base station high and the quality is poor

Embodiment Construction

[0027] In order to make the features and advantages of the present invention clearer, the present invention will be further described below in conjunction with specific embodiments with reference to the accompanying drawings.

[0028] The technical scheme proposed by the present invention is based on the following two premises: one is that a physical connection has been established between NodeB and RNC; the other is that the transmission between NodeB and RNC is based on ATM.

[0029] Referring to Fig. 1, the network structure of the present invention includes OMCR, BOOTP Server, file transfer protocol server (FTP Server), RNC and NodeB. Among them, the transmission between OMCR, BOOTP Server and FTP Server and RNC can be based on Ethernet, and the address of BOOTPServer is configured on RNC, so that RNC can route the BOOTP request sent by NodeB to BOOTPServer. According to the network planning, BOOTP Server is pre-configured with the information required by each NodeB to est...

Abstract

The invention discloses an establishment method of IPOA operation maintenance channel. The base station establishes BOOTP PVC and sends out BOOTP request message in broadcast mode on the BOOTP PVC; RNC transfers the request message to BOOTP server, which allocates operation maintenance channel PVC and IP address according to preset deployment and sends to the base station by RNC; the base station establishes IPOA operation maintenance channel according to acquired operation maintenance channel PVC and IP address. The invention has the advantages of flexible deployment of operation maintenance channel PVC, simple operation, applicable to several types of NodeB, remote simultaneous start of NodeB, wireless network maintainability improvement, running maintenance cost reduction and running maintenance quality improvement.

Description

technical field [0001] The invention relates to a technology for establishing an operation and maintenance channel, in particular to a method for establishing an operation and maintenance channel for an IP over ATM (IPOA, IP over ATM) operation and maintenance channel. Background technique [0002] With the development of wireless communication technology, the communication network is becoming more and more complex and large. As an important part of the wireless communication system, the base station (NodeB) has the characteristics of large number, wide distribution, difficult management and maintenance, etc. In order to solve the problem of NodeB management and maintenance, the protocol of the third generation communication network stipulates that the communication between the radio network controller (RNC) and NodeB can be carried out in the way of IPOA, that is, IP data packets are transmitted on ATM. Therefore, an IPOA operation and maintenance channel can be established...
