Method and a system for enabling multimedia ring-back-within the context of a voice-call
View Patent ↗A system for providing multimedia ring back for a voice-call is disclosed. The system may include an MMRB for VC control module and a network access module operatively connected to the MMRB. The network access module is adapted to interface the MMRB with external network components. The MMRB is responsive to indication that a caller is inviting a callee to join a voice-call wherein the caller and/or the callee is subscribed to an MMRB for VC service. The MMRB is responsive to indication that the callee received an invitation message and is now pending acceptance of the voice-call, for causing the caller to adapt its media-specification for the ongoing voice-call establishment process to a media-specification that is compatible with multimedia-content communication, thereby enabling a multimedia-content communication with the caller during at least a portion of the ongoing voice-call establishment process.
1. A method of providing multimedia ring back (“MMRB”) for a voice-call (“VC”), comprising:
in response to an indication that a caller is inviting a callee to join a voice-call with said caller, invoking said MMRB for VC service;
in response to said invoking:
generating a Request media message;
communicating said Request media message to a multimedia-resource management module;
receiving a Response media message having a reference to a selected multimedia-content resource, wherein said reference identifies a multimedia-content resource hosted on a multimedia distributor;
communicating to said caller, an Unstructured Supplementary Service Request (USSR) that includes said reference, wherein said caller (i) uses the reference to connect to said multimedia distributor, and (ii) initiates a multimedia communication session with said multimedia distributor,
wherein said multimedia communication session proceeds in parallel with an ongoing voice-session establishment process;
in response to a message indicating acceptance of said voice-call by said callee, ending said multimedia communication session, and initiating said voice-call between said caller and said callee; and
in response to an indication from said caller, and upon receiving a signal indicating that said voice-call has been terminated, establishing a multimedia communication session between said caller and said multimedia distributor for said selected multimedia content resource to facilitate further information or service acquisition associated with said selected multimedia content resource.
2. A system for providing multimedia ring back (“MMRB”) for a voice-call (“VC”), comprising:
an MMRB for VC control module; and
a service control point (“SCP”) gateway operatively connected to said MMRB for VC control module and adapted to interface said MMRB for VC control module with external network components,
an unstructured supplementary service data (“USSD”) gateway operatively connected to said MMRB for VC control module and adapted to interface said MMRB for VC control module with USSD enabled devices;
wherein said MMRB for VC control module responds to an indication that a caller is inviting a callee to join a voice-call with said caller and acceptance of said voice-call is pending, by:
generating a Request media message;
communicating said Request media message to a multimedia-resource management module;
receiving a Response media message having a reference to a selected multimedia-content resource, wherein said reference identifies a multimedia-content resource hosted on a multimedia distributor;
communicating to said caller, an Unstructured Supplementary Service Request (USSR) that includes said reference, wherein said caller (i) uses the reference to connect to said multimedia distributor, and (ii) initiates a multimedia communication session with said multimedia distributor;
in response to a message indicating acceptance of said voice-call by said callee, ending said multimedia communication session, and initiating said voice-call between said caller and said callee; and
in response to an indication from said caller, and upon receiving a signal indicating that said voice-call has been terminated, establishing a multimedia communication session between said caller and said multimedia distributor for said selected multimedia content resource to facilitate further information or service acquisition associated with said selected multimedia content resource.
