Method for registering multi-contact devices
First Claim
1. A method of registering in an IP multimedia Subsystem (IMS)-enabled network, two or more user agents associated with a multi-contact user device, the method comprising the steps of:
- associating with each of the two or more user agents, a unique user device identification (ID) that is unique to the multi-contact user device, wherein the unique user device ID is derived from a global permanent identifier associated with the multi-contact user device; and
providing, by each of the two or more user agents, the device ID to the IMS-enabled network;
wherein when a communication request is directed towards the multi-contact user device, a serving node in the IMS enabled network manages the communication request according to a predetermined handling scheme that prevents redirection of the communication request from one registered user agent to another in response to the detection of identical user device IDs.

Abstract
A technique is described allowing an IMS enabled network to terminate a communication request directed towards a user device in a well-defined way, even for cases in which multiple registrations for IMS are present that are related to the same physical user device. A method embodiment of this technique comprises registering multiple user agents for one and the same user device, wherein from each user agent contact information including a device ID identifying the user device is provided; and processing a communication request directed towards the user device, the processing comprising identifying multiple identical device IDs of registered contacts, and treating the communication request according to a predetermined handling scheme related to the detection of identical device IDs.

6. A method of controlling a communication request for a multi-contact user device in an IP multimedia Subsystem (IMS)-enabled network, wherein two or more user agents are associated with the multi-contact user device, the method comprising the steps of:
-
registering the two or more user agents with the IMS-enabled network, the registering step including providing to the IMS-enabled network by each user agent, a unique user device identification (ID) that is unique to the multi-contact user device, wherein the unique user device ID is derived from a global permanent identifier associated with the multi-contact user device; and processing by a serving node in the IMS-enabled network, a communication request directed towards the multi-contact user device, the processing step comprising; determining that multiple user agents suitable for terminating the communication request towards the multi-contact user device are registered with identical user device IDs; and managing the communication request according to a predetermined handling scheme related to the detection of identical device IDs, wherein the predetermined handling scheme prevents redirection of the communication request from one registered user agent to another in response to the detection of identical user device IDs. - View Dependent Claims (7, 8, 9)

10. A communication system comprising:
-
a single multi-contact user device having a unique user device identification (ID) that is unique to the multi-contact user device, wherein the unique user device ID is derived from a global permanent identifier associated with the multi-contact user device; and at least two user agents, each user agent acting for the single multi-contact user device, and each user agent being configured to provide the unique user device ID to an IP multimedia Subsystem (IMS)-enabled network during registration of the user agent; wherein when a communication request is directed towards the multi-contact user device, a serving node in the IMS enabled network manages the communication request according to a predetermined handling scheme that prevents redirection of the communication request from one registered user agent to another in response to the detection of identical user device IDs. - View Dependent Claims (11, 12, 13, 14, 15)

16. A serving node in an IP multimedia Subsystem (IMS) enabled network for controlling a communication request for a multi-contact user device having a device identification (ID) that is unique to the multi-contact user device, wherein the unique user device ID is derived from a global permanent identifier associated with the multi-contact user device, wherein the serving node is configured to:
-
register multiple user agents for the user device, wherein the serving node receives from each user agent, contact information including the unique user device ID for the multi-contact user device; and process a communication request directed towards the user device, wherein the serving node is configured to; determine that multiple user agents suitable for terminating the communication request towards the multi-contact user device are registered with identical user device IDs; and manage the communication request according to a predetermined handling scheme related to the detection of identical device IDs, wherein the predetermined handling scheme prevents redirection of the communication request from one registered user agent to another in response to the detection of identical user device IDs.
