Example Embodiment

[0030] One of the present invention is a method for identifying and processing signaling data at the IP data link functional layer. The method is used for identifying and controlling designated services and designated content of specific message types for signaling messages in the form of IP data messages. , In order to achieve the purpose of implementing specific services or controlling calls, including the following steps:

[0031] First, identify the service type of the signaling message from the IP data link, that is, compare and judge the service type of the received signaling message with the specified service type:

[0032] If the service type of the signaling message does not match the specified service type, keep the original message and implement direct communication;

[0033] If the service type of the signaling message matches the service type to be processed, further check whether the message type contains the specified information content field:

[0034] If the signaling...

Abstract

The invention provides a recognition processing method and a recognition processing device for signaling data on an internet protocol (IP) data link function layer. The device is connected between communication network nodes and transmits data through a data link layer, wherein the data link layer comprises a data link function unit; the recognition processing device comprises a content service control module; the data link layer transmits the detected acknowledged data message to the content service control module for processing; and after the message is subjected to recognition processing, the message is transmitted to the data link. By changing specified contents of the signaling message only, the existing protocols are not modified, session function of the IP layer and various upper protocol layers is not needed to be realized, call establishment and information transmission are controlled, network node equipment operating on the communication network is prevented from being modified or upgraded, and effectiveness, operability and feasibility of introducing novel services or upgrading the existing services are guaranteed.

Description

technical field [0001] The present invention relates to a method and device for identifying and processing IP signaling data used for communication control and routing. Specifically, on the premise of not changing the structure of the existing communication network, it is used to implement specific services such as communication network harassing call interception services A method and device for realizing communication control and route selection through control and processing of call message content in IP data packets. Background technique [0002] IP signaling network has been widely used in telecommunications fields such as fixed-line telephone, smart call, mobile communication, and short message service. The original No. 7 signaling network is also gradually transitioning to IP signaling network. The core support network of the network, every telephone call and the introduction of most new services are inseparable from the support of the IP signaling network. [0003] ...
