Problems solved by technology

However, in this method, the base station needs to perform bootstrapping broadcast on the default PVC, and the ATM cell carrying the broadcast is disposable, so the response packet may not be received, resulting in the inability to establish the IPOA channel in a timely and reliable manner.
In addition, this method is only how the base station obtains the IP address for IPOA when there is no IP address, and it cannot solve the problem that the base station cannot obtain a new IP address when the IP address changes during the later maintenance process, so that the IPOA channel cannot be established. maintain

Embodiment Construction

[0042] In order to gain an in-depth understanding of the IPOA channel automatic establishment and maintenance method of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] The solution of the present invention is based on the following premise: first, ATM transmission between the base station and the base station controller; second, a physical connection has been established between the base station and the base station controller.

[0044] As shown in Figure 2, the IPOA channel automatic establishment and maintenance method of the present invention comprises the following steps:

[0045] Step 1, establishing a default PVC between the base station and the base station controller;

[0046] Step 2, through the PVC established in step 1, the base station side initiates a bootstrap protocol (BOOTP) request in broadcast mode, and transmits the request to the bootstrap protoco...

Abstract

The invention discloses a automatic creation and maintenance method for IPOA channel, which comprises: building the default PVC between base station and its controller; promoting and sending the BOOTP request with broadcast mode on base station side by built PVC to controller; if within set response time, the base station does not acquire the BOOTP response packet contained its IP address, promoting the request again till acquiring the packet; the base station obtains its IP address from the packet and builds IPOA channel by IP address and PVC; then, the base station sends continually the BOOTP request to its controller according to monitor period and compares the IP address from response packet and current IP address, is there is difference, uses new address to build new IPOA channel. This invention ensures base station can acquire and update local IP address reliable and timely, as well as the automatic creation and maintenance method for IPOA channel.

Description

technical field [0001] The present invention relates to a data channel in the field of mobile communication, in particular to a method for automatically establishing and maintaining an IPOA channel (IP OVERATM) between a base station (NODE B) and a base station controller (RNC) in a wideband code division multiple access (WCDMA) system . Background technique [0002] As an important part of the wireless side in the WCDMA system, the base station NODE B has the characteristics of wide distribution, large number, and difficult management at the near end. In order to solve the problem of remote management of the NODE B system, it is stipulated in the 3GPP 25.442 agreement that an IPOA channel needs to be established between the base station NODE B and the base station controller RNC, that is, IP (Internet Protocol) is transmitted on ATM (Asynchronous Transfer Mode) data packets for centralized remote management on the RNC side. [0003] Existing technologies such as "A method...
