Abstract: A method for implementing Multimedia Caller Identification (MCID) service is disclosed. The method includes: if the network determines that the calling UE is an MCID service subscriber and determines that the called UE supports the MCID early media, the network negotiates the MCID early media with the called UE, and plays a MCID to the called UE if the negotiation succeeds. In addition, a system for implementing the MRBT service and MCID service is disclosed. The present invention enables the MCID service in an IP Multimedia Subsystem (IMS) so that users may use the multimedia services in the IMS and have a better experience.

Abstract: A user bandwidth notification method is disclosed, where the method includes: detecting, by a network side, available bandwidth of a user and a bandwidth requirement of a service currently used by the user; comparing, by the network side, the available bandwidth of the user and the bandwidth requirement of the service currently used by the user; and notifying, by the network side, the user of a bandwidth condition according to a comparison result. By using the present invention, the user can explicitly know that current poor service experience is caused by a mismatch between a user bandwidth condition and a current service bandwidth requirement and may further take an appropriate measure for handling and solving the problem.

Abstract: A method, system and apparatus for implementing a Multimedia Ring Back Tone (MRBT) service are provided. The method includes: receiving a call request originated by a calling terminal; parsing a tone playing policy specifying whether to play a caller tone or a callee tone or whether to filter a tone; performing caller tone media negotiation or callee tone media negotiation, or performing no tone negotiation according to the parsing result; and playing the caller tone or the callee tone to the caller, or playing no tone.

Abstract: A method for video sharing, which realizes video sharing between an originating UE and a terminating UE when the terminating UE is not IMS core network registered. The method includes the following steps: an originating UE sends a video sharing request containing a URI of callee to an application server; the application server determines that the terminating UE of the callee is not IMS core network registered and notifies the terminating UE to register; the terminating UE activates a GPRS connection and registers with the IMS core network; the originating UE and the registered terminating UE set up a sharing session via the application server; the originating UE and the terminating UE share video information. A system and apparatus for practicing this method is also disclosed.

Abstract: Disclosed is a method for implementing multimedia customized RBT (MRBT) service, including: receiving a call request sent from a calling terminal; determining the calling terminal's calling capability based on the call request; and selecting an MRBT playing manner based on the calling capability.
