Method for registering multi-contact devices

摘要

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.

1. A method of registering, in an IP Multimedia Subsystem (IMS), enabled network, two or more user agents associated with a single multi-contact user device, the method comprising:
associating each user agent with the single multi-contact user device, wherein the single multi-contact user device has unique user device identification (ID) that is unique to the single multi-contact user device, wherein the unique user device ID is derived from a global permanent identifier associated with the user device; wherein at least one of the two or more user agents has an overlapping capability with another at least one of the two or more user agents; and providing, by each user agent, the unique user device ID to the 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 contact to another in response to the detection of identical user device IDs.
