System and method of providing IMS services to users on terminating non IMS devices
First Claim
1. A method comprising:
- registering a public user identity for a terminating non-internet protocol device with a first network device in an internet protocol subsystem;
establishing an E.164 routing address associated with the terminating non-internet protocol device as a final destination of sessions to the public user identity;
establishing an internet protocol address of a second network device, wherein the second network device establishes a telephone number, distinct from the E.164 routing address, as an immediate destination for a session; and
routing internet protocol subsystem services to the terminating non-internet protocol device using a relationship between the public user identity, the E.164 routing address, and the internet protocol address of the second network device.

Abstract
Disclosed is a device in an IP Multimedia Subsystem (IMS) that provides IMS services to terminating non-IP (TNIP) devices. The method includes receiving a message to register a Public User Identity (PUID) at a TNIP device at a network-based device, the TNIP device being at an E.164 routing address, establishing, in a network device accepting communications where to send sessions destined for a PUID and providing information where to send sessions, the routing address as a final destination of sessions to the PUID based on the registration and an IP address of a network device with routing functionality based on telephone numbers as immediate destinations and using information from the registration to route to the TNIP device, after providing IMS services, using the relationship between the PUID, the routing address and the IP address of the network device with routing functionality based on telephone numbers.

11. A system comprising:
-
a processor; and a computer-readable storage medium having instructions stored which, when executed by the processor, result in the processor performing operations comprising; registering a public user identity for a terminating non-internet protocol device with a first network device in an internet protocol subsystem; establishing an E.164 routing address associated with the terminating non-internet protocol device as a final destination of sessions to the public user identity; establishing an internet protocol address of a second network device, wherein the second network device establishes a telephone number, distinct from the E.164 routing address, as an immediate destination for a session; and routing internet protocol subsystem services to the terminating non-internet protocol device using a relationship between the public user identity, the E.164 routing address, and the internet protocol address of the second network device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A computer-readable storage device having instructions stored which, when executed by a computing device, result in the computing device performing operations comprising:
-
registering a public user identity for a terminating non-internet protocol device with a first network device in an internet protocol subsystem; establishing an E.164 routing address associated with the terminating non-internet protocol device as a final destination of sessions to the public user identity; establishing an internet protocol address of a second network device, wherein the second network device establishes a telephone number, distinct from the E.164 routing address, as an immediate destination for a session; and routing internet protocol subsystem services to the terminating non-internet protocol device using a relationship between the public user identity, the E.164 routing address, and the internet protocol address of the second network device.
