3 Terms, definitions and abbreviations
3.1 Terms and Definitions
The following terms and definitions apply to this part of the GB/T 21645 of.
3.1.1
Call controller calcontroler
Call by call controller, call controller has two components, the calling/called party call controllers and network call controller.
3.1.2
The calling/called party call controller caling/caledpartycalcontroler
The controller associated with the call of a terminal, which can be located in a terminal system to be located at the distal end of the other, as a proxy execution
Function terminal system. The controller can assume a role or simultaneously assume both roles. support caller, the called party support.
3.1.3
Network Call Controller networkcalcontroler
Network Call Controller as two roles, one that supports the calling party, called party support another. The caller and the called party call controller
Call controller through one or more intermediate network call controllers interact.
3.1.4
Connection Admission Control connectionadmissioncontrol
Connection admission control is used to determine whether there are enough resources to accommodate a connection (or re-negotiation of resources during a call).
