Problems solved by technology
[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

Embodiment Construction
[0028] In the distributed wireless access system, in order to simplify the corresponding operation process when the network sub-node actively exits the distributed wireless access system, in the embodiment of the present invention, the first network sub-node is encapsulated based on the network layer protocol to request for exit The request message of the distributed wireless access system, and the request message based on the network layer protocol is encapsulated based on the MAC layer protocol, and the request message is sent to the first network master node to which it belongs; the first network master node is based on the network layer protocol. A response message for instructing it to exit the distributed wireless access system is encapsulated, and the response message based on the network layer protocol is encapsulated based on the MAC layer protocol, and the response message is returned to the first network sub-node.
[0029] In this embodiment, each network node encaps...

The invention discloses a method for quitting a distributed wireless access system, which comprises the following steps: a first network child node encapsulates a request message which asks for quitting the distributed wireless access system based on the network layer protocols, encapsulates the request message which is based on the network layer protocols on the foundation of the MAC layer protocols, and sends the request message to a belonging first network master node; the first network master node encapsulates a response message used for indicating the first network child node for quitting the distributed wireless access system based on the network layer protocols, encapsulates the response message which is based on the network layer protocols on the foundation of the MAC layer protocols, and returns the response message to the first network child node; and consequently protocol conversion is not needed between network nodes in a quitting negotiation process, thus simplifying operating process to a certain degree, improving the interoperability between network nodes, and consequently lowering system running cost. The invention simultaneously discloses a corresponding communication device and a corresponding communication system.
Description
technical field [0001] The present invention relates to the field of communications, and in particular, to a method, device and system for exiting a distributed wireless access system. Background technique [0002] In an existing distributed wireless access system, when a network node (eg, a base station) exits the distributed wireless access system, other network nodes do not perform any processing on it, which may easily cause some network nodes to fail. In order to avoid the above situation, the existing solution is: each network node uses the MAC protocol to exchange information, so as to complete the corresponding network resource adjustment in the exit process. [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 MAC protocols; and the existing distri...
