Method and device for establishing communication connection between protocol server boards and line terminal board

Abstract

The invention provides a method and a device for establishing the communication connection between protocol server boards and a line terminal board in an NGN network. The method comprises the following steps that: the line terminal boards of access nodes send service request registration messages to the shelf management boards of the access nodes; after the shelf management boards receive the service request registration messages, one or more received service indication messages are used to judge whether the one or more service indication messages have the service types matched with the service types requested by the service request registration messages or not, if so, the service request registration messages containing the service types are sent to the line terminal board. The inventionsimplifies the management work of the protocol server boards, and simultaneously reduces the overhead of network messages generated by the protocol server boards trying to establish the connection with the all line terminal boards allocated to the protocol server board, and the line terminal board and the protocol server board in each access node can be inserted and extracted at any time so as togreatly improve the flexibility of system configuration.

Description

technical field [0001] The invention relates to an access node in the NGN network, in particular to a shelf management board, a protocol server board and a line terminal board in the access node. Background technique [0002] For access nodes in NGN (Next Generation Network, next-generation network), many new protocols are used for session / media control, IP-based signaling transmission, for example, H.248, SIP (Session Initiation Protocol, session initial protocol), SIGTRAN (Signal Transport, signaling transport protocol), etc. Therefore, concentrating these new protocols in a centralized system unit is a reasonable architecture, which not only saves cost, but also reduces the management overhead of the NGN core network. However, in this centralized architecture, the line termination board in the access node needs to communicate with the centralized protocol server board to successfully access the NGN core network. [0003] In the prior art, each protocol server board has ...

Problems solved by technology

[0007] It can be seen that every time the protocol server board is started, it must try to establish an internal communication connection with each line terminal board configured for it. Therefore, for the protocol server board, its management workload is very heavy

[0008] Moreover, when a certain line termination board configured to the protocol server board has not been started, the protocol server board will continuously send an internal communication connection establishment request message to the line termination board until the line termination board starts and sends an internal communication connection establishment request message to the line termination board. Response messages to the protocol server board, therefore, will cause a lot of network message overhead when the protocol server board tries to establish a communication connection with each line termination board configured to it
