Method for processing node defect of distributed wireless access system

Abstract

The invention discloses a method for processing node failure in a distributed wireless access system. The method comprises the following steps: after determining that a first network subnode within the self control range has a fault, a network main node utilizes a notification message used for prompting notification message to adjust the network resource by a network layer protocol encapsulation and a notification message based on the protocol encapsulation of an MAC layer and a network layer protocol and transmits the notification messages to other network subnodes which have safety relation with the first network subnode; and after receiving the notification message, the other network subnodes carry out corresponding adjustment to self network resources, utilizes a reply message used for notifying that the adjustment of the network resources is completed by the network layer protocol encapsulation and a reply message based on the protocol encapsulation of the MAC layer and the network layer protocol and returns the notification messages to the network main node. Therefore, when a certain network subnode has a fault, other network subnodes which have safety relation with the network subnode can complete adjustment of the network resources without carrying out protocol conversion, thus simplifying operation process to a certain extent, improving the interoperability of all the network nodes, and further reducing the operation cost of the system. The invention discloses a corresponding communication device and a communication system simultaneously.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, device and system for handling node faults in distributed wireless access bamboo weaving. Background technique [0002] In an existing distributed wireless access system, when a network node (for example, a base station) fails, other network nodes use the MAC protocol to perform information exchange, thereby completing subsequent network resource adjustments. [0003] However, using the MAC protocol to adjust network resources between network nodes has the following disadvantages: poor interoperability. Because each network node does not use a unified MAC protocol, network nodes produced by different manufacturers use their own configured MAC protocols; and existing distributed wireless access systems generally use multi-vendor solutions (that is, use multiple vendors production network nodes), then the use of the MAC protocol between network nodes to adjust network resources...

[0003] However, the use of the MAC protocol to adjust network resources between network nodes has the following disadvantages: poor interoperability

Because each network node does not use a unified MAC protocol, network nodes produced by different manufacturers use their own configured MAC protocols; and existing distributed wireless access systems generally use multi-vendor solutions (that is, use multiple vendors production network nodes), then the use of the MAC protocol between network nodes to adjust network resources will cause frequent protocol conversions, which greatly increases the cost of system operation
