Abstract
A method of installing a default dialing or numbering plan identity into a user terminal comprising an IMS client. The method comprises, at or following registration of a user of the user terminal to an IMS network, receiving at the terminal from the network a dialing or numbering plan identity and saving the identity as a default identity at the terminal, wherein the default dialing or numbering plan identity is subsequently used by the IMS client as a phone context.
Claims16
A method of installing a default dialling or numbering plan identity into a user terminal comprising an IMS client, the method comprising, at or following registration of a user of the user terminal to an IMS network, receiving at the terminal from the IMS network a dialling or numbering plan identity and saving the identity as a default identity at the terminal, wherein the default dialling or numbering plan identity is subsequently used by the IMS client as a phone context, as required by IETF RFC 3966.
A user terminal comprising an IMS client, the user terminal being configured, at or following registration of the user of the user terminal with an IMS network, to receive a default dialling or numbering plan identity from the network and to save the default dialling or numbering plan identity at the terminal for subsequent use by the IMS client as a phone context as required by IETF RFC 3966.
Apparatus for configuring an IMS client of a user terminal with a default dialling or numbering plan identity, the apparatus being configured for use within an IMS core network and comprising:
- a processor for determining a home dialling or numbering plan identity for a user of said user terminal;
- a sending unit for sending said home dialling or numbering plan identity to said user terminal;
- and
- a CSCF configured to receive a call set-up request that includes said identity as a phone context, as required by IETF RFC 3966, and to use the identity to establish a destination URI for the call.
A method of handling SIP messages in an IP-based communication network, the method comprising:
- at or following registration of a user with an IMS network, sending to the user's terminal from the network, a default dialling or numbering plan identity;
- receiving the dialling or numbering plan identity at said user terminal and saving the identity for use by an IMS client;
- and
- sending a SIP session initiation request from the user terminal to the IMS network including a Local Tel URI and said default dialling or numbering plan identity as a phone context as required by IETF RFC 3966.
