摘要： A method of implementing a Communication Barring, CB, service within an IP Multimedia Subsystem, IMS, network in respect of an ongoing IMS session or an IMS session in early session phase. The method comprises, at an Application Sever, AS, within the IMS network, parsing SIP messages relating to the session to detect an attempt to add one or more media streams to the session. CB service rules are applied to determine the allowability of the media stream(s) being added. If the media stream(s) being added is (are) not allowed, action is taken to prevent its addition, and otherwise allowing the media stream addition to proceed.
