Method and system for media resource scheduling

An IMS-based media resource scheduling method, comprising:

• requesting, by an Application Server, AS, media server information from a media locating functional entity;
• determining, by the media locating functional entity, a media server and returning information about the determined media server to the AS;
• and
• initiating, by the AS, a media resource request to the determined media server.

An IMS-based media resource scheduling method, comprising:

• obtaining information about at least one media server in the present IMS domain and/or other IMS domains;
• determining a media server from the at least one media server;
• and
• initiating a media resource request to the determined media server.

An IMS-based media resource scheduling system, comprising:

• an Application Server, AS, a Media Resource Locating Function, MRLF or Media Resource Broker Function, MRBF, and at least one media server,
• wherein the MRLF or MRBF is in communication with the AS and the at least one media server,
• the MRLF or MRBF is configured to determine a media server for providing stream media service to a User Equipment, UE, and
• the AS is configured to initiate or receive a stream media service request sent from the UE and return information about the determined media server to the UE.

An IMS-based Media Resource Locating Function, MRLF, comprising:

• a request receiving unit, configured to receive a request for providing media server information;
• a media server determining unit, configured to determine a media server for providing stream media service to a User Equipment, UE, based on the received request for providing media server information;
• and
• a media server information providing unit, configured to provide information about the determined media server to an Application Server, AS.

An IMS-based Media Resource Broker Function, MRBF, comprising:

• a request receiving unit, configured to receive a media resource request;
• a media server determining unit, configured to determine a media server for providing stream media service to a User Equipment, UE, based on the received media resource request;
• and
• a request forwarding unit, configured to forward the received media resource request to the determined media server.

An IMS-based media resource control functional entity, independent of a Media Resource Function Controller, MRFC, and configured to control at least one media resource delivery functional entity which stores stream media content, comprising:

• a request receiving unit, configured to receive a media resource request;
• a media server determining unit, configured to determine a media server for providing stream media service to a User Equipment, UE, based on the received media resource request;
• and
• a request forwarding unit, configured to forward the received media resource request to the determined media server.

An IMS-based Media Resource Function Controller, MRFC, comprising:

• a request receiving unit, configured to receive a media resource request;
• a media server determining unit, configured to determine a media server for providing stream media service to a User Equipment, UE, based on the received media resource request;
• and
• a request forwarding unit, configured to forward the received media resource request to the determined media server.
