Problems solved by technology

[0008] Since the configuration of increasing the bandwidth is required before the upgrade, and the configuration of reducing the bandwidth is also required after the upgrade is completed, and the number of base stations that usually needs to be maintained is large, so the operation of reconfiguring the bandwidth is cumbersome and the workload is heavy. Big;
[0009] At the same time, because this method needs to modify the base station configuration data during the upgrade process, it increases the risk of base station upgrade and maintenance failure

Embodiment Construction

[0032] The core idea of ​​the present invention is to adopt the flow control technology control based on the ATM protocol to control and manage the flow of the remote maintenance channel in the mobile communication system. The present invention is applicable to all systems that use ATM as the underlying transmission protocol and transmit in the IP over ATM mode. Including 3G system.

[0033] The IUB interface of the 3G system is based on ATM transmission, and the ATM network flow control technology can provide different QoS (Quality of Service) for network applications.

[0034] The service system provided by the ATM layer includes the following two service levels:

[0035] rt-VBR: real-time variable bit rate service;

[0036] nrt-VBR: Non-real-time variable bit rate service;

[0037] The ATM network flow control technology specifies the flow parameters of the two types of services, and also specifies how the two-level leaky bucket handles the default cells in the service, t...

Abstract

The invention relates to a flux manage method for remote maintained channel of mobile communication system. Said method comprises: distributing a flux manage mode based on the asynchronous transmission mode ATM protocol to the remote maintained channel; and transmitting the maintained data based on distributed flux manage mode. The invention is realized base on the character of band width dynamic channel of remote maintained channel which can avoid additional distribution in the upgrade of base station. The invention can keep maximum band width for the service in daily operation and supply most band width in upgrade. And the invention uses general ATM (asynchronous transmission mode) technique, to conform the system compatibility and safety.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a flow management method of a remote maintenance channel in a mobile communication system. Background technique [0002] In the mobile communication system, the number of base stations is very large, and the geographical locations are dispersed. In the process of network operation and maintenance, it is necessary to maintain these base stations, query base station operating information, locate faults, and upgrade base station software. Therefore, base stations are required to have remote maintenance functions, including daily maintenance and upgrade maintenance. [0003] In a 3G (third generation) system, the channel for remote maintenance is usually carried on the same physical link as the service of the IUB interface (that is, the interface between the base station and the radio network controller). The physical link can be E1, T1, optical fiber or others etc. ...
