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

[0027] The core idea of ​​the present invention is to use ATM protocol-based flow control technology to control and manage the flow of remote maintenance channels in mobile communication systems. The present invention is applicable to all systems that use ATM as the underlying transmission protocol and transmit in IP over ATM mode. Including 3G system.

[0028] The 3G system IUB interface is based on ATM transmission, and ATM network flow control technology can provide different QoS (Quality of Service) for network applications.

[0029] The business system provided by the ATM layer includes the following two business levels:

[0030] rt-VBR: Real-time variable bit rate service;

[0031] nrt-VBR: non-real-time variable bit rate service;

[0032] The ATM network flow control technology specifies the flow parameters of the two types of services. It also specifies how the two-level leaky bucket handles the default cells in the service, that is, specifies the flow management methods o...

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 present invention relates to the field of mobile communication technology, 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 geographically dispersed. In the process of network operation and maintenance, these base stations need to be maintained, query base station operating information, fault location, and upgrade of base station software. Therefore, base stations are required to have remote maintenance functions, including routine maintenance and upgrade maintenance. [0003] In the 3G (third generation) system, the remote maintenance channel is usually carried on the same physical link as 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. [0004] Since the maintenance ch...
