Embodiment Construction

[0042] The method for collecting calling and called gatekeeper information proposed by the present invention, when the local gateway initiates a call to the gateway managed by the remote gatekeeper, encodes the local first-level gatekeeper or remote gatekeeper registered on the local top-level gatekeeper, and establishes The mapping table between the gatekeeper code and the corresponding gatekeeper information; its timing diagram is as follows Figure 4 As shown, when the local gateway initiates a call to the gateway managed by the remote gatekeeper, after receiving the LCF sent by the remote gatekeeper, the local top-level gatekeeper searches the above mapping table to find the code of the remote gatekeeper; In the LCF sent by the local lower-level gatekeeper, add the code of the remote gatekeeper retrieved above; after the local lower-level gatekeeper receives the LCF, take out the purpose information in the message, keep the code, and send the ACF message to the local gatewa...

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.
