Method for collecting called gate keeper information

Abstract

Since mapping each other between gatekeeper coding and gatekeeper information, as well as remote gatekeeper coding and called number carried in target information of LCF message, ARQ message and standard Setup message, normal transmission can be realized for the remote gatekeeper device kept to standard H.323 protocol. Advantages of the invention are as follows. Detailed information between calling and called gatekeepers can be obtained for managers to make balance conveniently. The invention uses standard RAS message totally without any private expansion so as to guarantee compatibility with gatekeepers made by other manufactures.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a method for collecting information of calling and called gatekeepers. Background technique [0002] With the development of IP telephony, IP telephony / fax technology has become a hot spot since the development of the Internet. IP phone / fax network generally consists of gateway, gatekeeper, IP network supporting IP phone / fax transmission, and corresponding network management, billing and business systems. The IP telephony gatekeeper is the key device of the entire IP telephony system, responsible for building the IP telephony network and completing the routing management, security management and connection with other networks of the IP telephony network. [0003] For an operational system, it should be able to perform billing and information collection according to the billing object, and be responsible for sending the collected information to the billing center.

Problems solved by technology

[0019] The disadvantage of the prior art is that the LCF message and the ACF message in the standard Registration, Admission and Status (Registration, Admission and Status, hereinafter referred to as RAS) protocol cannot carry the relevant information of the calling and called gatekeepers, and generate call detail records For the convenience of settlement, it is often necessary to obtain the relevant information of the calling and called gatekeepers

If appropriate private extensions are made to LCF and ACF messages, intercommunication with gatekeepers from other manufacturers will be affected due to private extensions
