METHOD AND SYSTEM FOR DISCOVERING THE ACCESS OF THE CALL CONTROL SYSTEM

摘要

A method for discovering the access of the call control system, includes: authentication, authorization and accounting server allocates the access point address of the call control system for terminals, and sends the access point address of the call control system to terminals. Another method for discovering the access of the call control system and two systems for discovering the access of the call control system are also provided. Through authentication, authorization and accounting server or HA allocating the access point address of the call control system for terminals and sending the access point address of the call control system to terminals, the terminals can also obtain the access point address of the call control system without interacting with DHCP server in DHCP process, to achieve that terminals obtain the call access point address and then discover the call access more flexible and to facilitate centralized management of the access point of the call control system due to the unified management and allocation of the access point address of the call control system by AAA server or HA.
