摘要： The present invention relates generally to telecommunication services and, in particular, to a system and method of managing a call, particularly with regard to a modification to bearer characteristics. In one aspect the invention provides a method and system of managing a call in a telecommunication system, the telecommunication system including a network having at least one call controller effecting a call control function and at least one bearer controller effecting a bearer control function, the call controller and the bearer controller separated by a vertical control protocol interface, including providing in at least one message, communicated within the telecommunication system, an indication of the capability of the at least one bearer controller to modify a characteristic of a bearer; and receiving and storing said indication in the at least one call controller. In another aspect the invention provides a media gateway controller being operable to request indications and to receive indications from at least one media gateway of the capability of the at least one media gateway to modify a characteristic of a bearer established by the at least media gateway. In a preferred embodiment the invention provides a media gateway controller operable to receive requests for an indication of the capability of the at least one media gateway to modify a characteristic of a bearer established by the media gateway.
