Abstract

IMS networks and methods are disclosed for storing information on the access network of a user in a subscriber profile for the user. When a communication device of a user attempts to register with an IMS network, a P-CSCF receives a register request message from the communication device, and identifies access network information for the user. The P-CSCF then transmits another register request message to an S-CSCF that includes the access network information, and the S-CSCF in turn forwards the access network information to an HSS. The HSS then stores the access network information in the subscriber profile for the user. Nodes in the IMS network that retrieve the subscriber profile may acquire the access network information to provide services based on the access network information.

Claims14

Dependent claims

An IMS network adapted to store access network information for a user in a subscriber profile for the user, the IMS network comprising:

a proxy-call session control function (P-CSCF) adapted to receive a first register request message from a communication device of the user, to identify access network information for an access network providing service to the communication device of the user, to generate a second register request message and include the access network information in the second register request message, and to transmit the second register request message for receipt by a serving-call session control function (S-CSCF);
the S-CSCF adapted to receive the second register request message, to identify the access network information in the second register request message, to generate a third register request message and include the access network information in the third register request message, and to transmit the third register request message for receipt by a home subscriber server (HSS);
and
the HSS adapted to receive the third register request message, to identify the access network information in the third register request message, and to store the access network information in the subscriber profile for the user.

A method of operating an IMS network to store access network information for a user in a subscriber profile for the user, the method comprising:

receiving a first register request message in a proxy-call session control function (P-CSCF) from a communication device of the user;
identifying access network information for an access network providing service to the communication device of the user;
generating a second register request message and including the access network information in the second register request message;
transmitting the second register request message from the P-CSCF to a serving-call session control function (S-CSCF);
identifying, in the S-CSCF, the access network information in the second register request message;
generating a third register request message and including the access network information in the third register request message;
transmitting the third register request message from the S-CSCF to a home subscriber server (HSS);
identifying, in the HSS, the access network information in the third register request message;
and
storing the access network information in the subscriber profile for the user.
