Abstract

Apparatus, and an associated method, for generating a bearer setup request in a mobile, or other, communication system. An application-level bearer setup request generator is positioned at the application level of the communication system. A request is forwarded to a transport level. And a bearer setup request signal generator, located at the transport level, generates a transport-level bearer setup request that is routed to the bearer manager. Bearer setup is performed by the bearer manager and a response is provided through the transport layer to the application level, and back to a communication node when the bearer setup is performed.

Claims

1. An apparatus for facilitating bearer setup initiated by a network, the apparatus comprising:

a first bearer setup request generator associated with a first application-level entity, said first bearer setup request generator configured to;

generate a first application-level bearer setup request to induce a bearer manager to create a bearer between a first node and a second node, wherein the first bearer setup request is free of network address identifiers for the bearer manager; and

provide the first application-level bearer setup request to a transport-level entity; and

a second bearer setup request generator associated with an AAA entity, the second bearer request generator configured to;

generate, upon receiving an indication of the first bearer setup request, a transport-level bearer setup request to induce the bearer manager to create the bearer between the first node and the second node.

2. The apparatus of claim 1 wherein the network comprises a first network portion and at least a second network portion, the first network portion defining a home network of the first node, and the second network portion defining a visited network of the first node, and wherein the first application-level entity with which said first bearer setup request generator is associated and the AAA entity with which said second bearer setup request generator is associated are positioned within the visited network portion.

3. The apparatus of claim 2 wherein the AAA entity comprises a home-network AAA entity and a visited network AAA entity, and wherein the first bearer setup request is sent by said first bearer setup request generator to the home-network AAA entity.

4. The apparatus of claim 3 wherein said second bearer setup request generator is to generate the transport-level bearer setup request by way of the visited-network AAA entity to the selected bearer manager.

5. The apparatus of claim 4 wherein the transport-level bearer setup request message to be generated by said second bearer setup request message generator comprises an AAA-protocol message.

6. The apparatus of claim 5 wherein the selected bearer manager to which the transport-level bearer request is to be delivered is to generate a response message, and wherein said second bearer setup request generator is further to detect the response message.

7. The apparatus of claim 6 wherein the response message to be generated by the selected bearer forms an AAA-protocol message.

8. The apparatus of claim 6 wherein said second bearer setup request generator is further to return an indication of the response message to said first bearer setup request generator.

9. The apparatus of claim 8 wherein said first bearer setup request message generator is further to generate an application-level message for communication to the communication node, the application-level message indicative of said response message.

10. A method for facilitating bearer setup of a network, the method comprising:

selectably generating a first application-level bearer setup request to induce a bearer manager to create a bearer between a first node and a second node, wherein the first bearer setup request is free of network address identifiers for the bearer manager; and

providing the first application-level bearer setup request to a transport level AAA (Authentication Authorization Accounting) entity; and

generating a second bearer setup request to induce the bearer manager to create the bearer between the first node and the second node.

11. The method of claim 10, further comprising routing, from the transport-level AAA entity, a separate-level signaling-layer request signal to the bearer manager.
