Abstract
A network element for use in an IMS network is disclosed herein. The network element includes a communication interface operable to receive a SIP request message from a communication device, such as an SIP invite. The network element also includes a communication processor operable to process the SIP request message, extract registration information from a header of the SIP request message, and update a registration of the communication device with the IMS network based on the registration information.
Claims19
A network element of an IMS network, comprising:
- a communication interface operable to receive a Session Initiation Protocol (SIP) request message from a communication device;
- and
- a communication processor operable to process the SIP request message, to extract registration information from a header of the SIP request message, and to update a registration of the communication device with the IMS network based on the registration information.
A communication device operable to communicate with an IMS network, the communication device comprising:
- a communication interface operable to exchange data with the IMS network;
- and
- a communication processor operable to transfer a REGISTER request to the IMS network to register with the IMS network and initiate a timer that establishes a registration duration with the IMS network;
- wherein the communication processor is further operable to format a header of a Session Initiation Protocol (SIP) request message with registration information used in maintaining the registration with the IMS network, and to transmit the SIP request message to the IMS network to initiate a session in the IMS network.
A method of continuing a registration of a communication device with an IMS network, the method comprising:
- receiving a Session Initiation Protocol (SIP) request message from the communication device requesting a session;
- determining a registration status of the communication device with the IMS network by determining a remaining registration duration of the communication device with the IMS network;
- processing header information within the SIP request message to extract registration information;
- and
- increasing the registration duration based on the extracted registration information.
A Session Initiation Protocol (SIP) message operable within a SIP based network, the SIP message comprising:
- a header that comprises SIP registration indicators used to maintain a registration period for a session within the SIP based network.
