Abstract
A method and a system for implementing ring back tones and ring back images in the VP service provides quality-assured and customized ring back tones and ring back images. A control module plays the ring back tones and ring back images for calling UEs through a voice and image channel defined in the VP series of protocols by resolving or pre-negotiating the voice and image coding formats supported by the calling UEs.
Claims16
A method for implementing ring back tones and ring back images in a video phone (VP), service in a communication system, the method comprising:
- obtaining, by a control module of the communication system, voice and image coding formats supported by a calling User Equipment (UE) in the VP service, by resolving protocol interaction information of the VP service between the calling UE and a called UE;
- playing, by the control module, ring back tones and ring back images for the calling UE in the voice and image coding formats supported by the calling UE through a voice and image channel defined in VP series of protocols, wherein the ring back tones and ring back images are customized by a core network (CN) of the communication system.
A control module in a communication system for implementing ring back tones and ring back images in a video phone (VP) service, the control module comprising:
- an acquiring unit, adapted to acquire, by resolving protocol interaction information between a calling user equipment (UE) and a called UE, voice and image coding formats supported by the calling UE in the VP service;
- and
- a playing unit, adapted to play ring back tones and ring back images for the calling UE in the voice and image coding formats supported by the calling UE through a voice and image channel defined in VP series of protocols, wherein the ring back tones and ring back images are customized by a core network (CN) of the communication system.
A communication network system, comprising:
- a core network (CN) communicatively connected with a calling party and a called party, wherein the CN is configured to:
- obtain voice and image coding formats supported by the calling party by resolving protocol interaction information between the calling party and the called party,
- determine a ring back tone and a ring back image in the voice and image coding formats supported by the calling party, and
- play, through a voice and image channel defined in video phone (VP) series of protocol, the ring back tone and ring back image for the calling party.
