Abstract

A system and method for processing a plurality of requests for multi-media services received at a call control element (CCE) defined on the system from a plurality of IP-communication devices. The system includes at least one Network Routing Element (NRE), a Service Broker (SB), a media sever, a plurality of application servers (ASs) and a plurality of border elements, all of which are coupled to the CCE. The CCE is adapted to receive requests for multi-media services and to generate subsequent requests for the multi-media services, which are communicated to the SB for processing. The subsequent requests can each include a Session Initiation Protocol (SIP) message including a message identifier portion having at least a first predetermined information field and a second predetermined information field. The message identifier portion of the SIP message declares the content and format of the SIP message to a recipient device defined on the system.

Claims

1. A method of processing multi-media service requests received at a multi-media services provider system to form a multi-media communication path between a first communication device and a second communication device of a plurality of communication devices, the method comprising:

receiving a first request message for a multi-media service at a call control element located on the multi-media services provider system;

processing the first request message at the call control element for generating a second request message for the multi-media service and including a message content identifier portion having a content-type header portion having a media type field and a media subtype field identifying an advanced intelligent service; and

processing the second request message at a service broker element located on the multi-media services provider system for identifying a format and content of the second request message, wherein the identifying the format and content of the second request message includes identifying the advanced intelligent service requested by the second request message.

2. The method for processing multi-media service requests of claim 1, further including:

receiving the first request message for the multi-media service at an application server located on the multi-media services provider system; and

processing the first request message at the application server to identify the advanced intelligent service associated with the first request message.

3. A system for processing multi-media service requests to form a multi-media communication path between a first communication device and a second communication device of a plurality of communication devices, the system comprising:

a call control element located on the system for receiving a first request message for a multi-media service from the first communication device and processing the first request message to generate a second request message for the multi-media service, wherein the second request includes a message identifier portion having a content-type header portion having a media type field and a media subtype field identifying an advanced intelligent service; and

a service broker element located on the system for receiving and processing the second request message to identify a format and content of the second request message, wherein the identifying the format and content of the second request message includes identifying the advanced intelligent service requested by the second request message.

4. The system for processing multi-media service requests of claim 3, further comprising:

an application server located on the system.

5. The system for processing multi-media service requests of claim 3, further comprising:

a border element located on the system.

6. A non-transitory computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor, cause the processor to perform a method for processing multi-media service requests to form a multi-media communication path between a first communication device and a second communication device of a plurality of communication devices, comprising:

receiving a first request message for a multi-media service at a call control element located on the multi-media services provider system;

processing the first request message at the call control element for generating a second request message for the multi-media service and including a message content identifier portion includes a content-type header portion having a media type field and a media subtype field identifying an advanced intelligent service; and

processing the second request message at a service broker element located on the multi-media services provider system for identifying a format and content of the second request message, wherein the identifying the format and content of the second request message includes identifying the advanced intelligent service requested by the second request message.

7. The non-transitory computer-readable medium for processing multi-media service requests of claim 6, further including:

receiving the first request message for the multi-media service at an application server located on the multi-media services provider system; and

processing the first request message at the application server to identify the advanced intelligent service associated with the first request message.
