Problems solved by technology
[0017] 1. When there are a large number of multi-level gatekeepers, the multi-level authentication message takes a long time and the analysis is slow, resulting in slow user connection;
[0018] 2. The gatekeeper needs to save other cascade network guard information (the cascade network gatekeeper is fixed, but the area number of the cascade network gatekeeper may be updated frequently), configuration is difficult, and modification and maintenance are inflexible
[0019] 3. The terminal device cannot obtain the number analysis plan (dial plan) of the entire network in real time, and it is only updated by the administrator to modify the configuration or use the # key to end, timeout, etc., which is inconvenient for users

Embodiment Construction
[0038] According to the provisions of the H.323 protocol, the gatekeeper is used to provide management and control functions of H.323 endpoints and calls, and its specific contents include:
[0039] (1) Registration management: used for the registration and deregistration of the gateway to the gatekeeper
[0040] Registration message processing: the gateway sends a registration request message to the gatekeeper to request registration. According to the configured data, the gatekeeper judges whether the gateway sending the registration request message is within the jurisdiction of the gatekeeper, whether the gatekeeper ID matches, and whether the security verification is passed, so as to decide whether to send a registration confirmation or a registration rejection message.
[0041] Deregistration message processing: The deregistration message is used for deregistration from the gateway to the gatekeeper, that is, deregistration. The gateway sends a deregistration message to t...

The method is applied to between cascaded netkeepers, or between netkeeper and terminal. Content in use for assistant calling control is added to RAS message utilized between cascaded netkeepers, or between netkeeper and terminal. The said netkeeper or terminal carries operation based on content of calling control in the said RAS message. The method strengthens original loose mechanism for coupling cascaded netkeepers. Using the strengthened coupling mechanism, the scheme for solving dialed number between netkeepers in multistage can be simplified easily. The invention also discloses method for parsing information of real time number between netkeeper and terminal so as to raise flexibility of number dialed by user.
Description
technical field [0001] The present invention relates to a method for strengthening the coupling mechanism between gatekeepers (Gatekeepers, also known as gatekeepers, gatekeepers), and in particular to a method for strengthening the coupling mechanism between gatekeepers by utilizing the registration function inside the gatekeepers. Voice over Internet (VoIP) technical field. Background technique [0002] VoIP is a packetization and digital transmission technology based on IP technology. Its basic principle is: compress and encode voice data through voice compression algorithm, then package these voice data according to IP and other related protocols, and transfer the data through IP network The packet is transmitted to the receiving place, and then these voice data packets are stringed together, and after decoding and decompression processing, the original voice signal is restored, so as to achieve the purpose of transmitting voice through the IP network. It promotes the u...
