Abstract
The present disclosure discloses a method for providing multicast services, which includes receiving a multicast service request sent by a UE through an IMS network, obtaining the media transmission parameters of the multicast media streams, sending a response to the UE through the IMS network with the media transmission parameters carried in the response, and sending the multicast media streams corresponding to the media transmission parameters to the UE. Further, a system providing multicast services and a multicast service support system is disclosed.
Claims19
A method for providing multicast services, comprising:
- receiving, by an application server (AS), a multicast service request sent by a User Equipment (UE) through an IMS network, wherein the multicast service request comprises a multicast service identifier and a Channel ID;
- analyzing, by the AS, the Channel ID carried in the multicast service request, and requesting the media transmission parameters corresponding to the Channel ID from a Service Schedule Function (SSF);
- receiving, by the AS, the media transmission parameters from the SSF, wherein the media transmission parameters comprise multicast address;
- sending, by the AS, a response carrying the media transmission parameters to the UE through the IMS network;
- and
- sending, by a Media Resource Function (MRF), multicast service media streams corresponding to the media transmission parameters to the UE;
- wherein, before receiving, by the AS, the media transmission parameters from the SSF, the method further comprises:
- finding, by SSF, whether multicast service content corresponding to the media transmission parameters is scheduled, and
- if yes, providing the media transmission parameters;
- if no, obtaining a service scheduling plan, obtaining content metadata and content source address from a Content Management Function (CMF) according to the service scheduling plan, and obtaining multicast address and/or port information;
- sending, by the SSF, a content scheduling message carrying the multicast address and/or port information, the content metadata, and the content source address to the MRF;
- and
- obtaining, by the MRF, multicast service content from a media content source device according to the content source address.
A system for supporting multicast service, comprising:
- An Application Server (AS), configured to receive a multicast service request sent by a User Equipment (UE) through an IMS network, wherein the multicast service request comprises a multicast service identifier and a Channel ID, analyze the Channel ID carried in the multicast service request, request the media transmission parameters corresponding to the Channel ID from a Service Schedule Function (SSF), receive the media transmission parameters from the SSF, and send a response carrying the media transmission parameters to the UE through the IMS network, wherein the media transmission parameters comprise multicast address;
- the SSF, configured to find whether multicast service content corresponding to the media transmission parameters is scheduled, if yes, providing the media transmission parameters to the AS;
- otherwise, obtain a service scheduling plan, obtain content metadata and content source address from a Content Management Function (CMF) according to the service scheduling plan, obtain multicast address and/or port information, and send a content scheduling message carrying the multicast address and/or port information, the content metadata and the content source address to a MRF;
- the Media Resource Function (MRF), configured to obtain multicast service content from a media content source device according to the content source address, and send the multicast service media streams corresponding to the media transmission parameters to the UE.
