An apparatus, and an associated method, for directing communications of a communication session to a selected communication device, or devices, of a group of commonly-registered devices. A device-direction policy is created and stored at a network entity. The policy identifies preferred devices to which communications of a communication session are to be provided. A SIP Invite, or other communication-session initiation message, is provided to the network entity. The network entity detects the message, accesses the policy, and forwards on the message in accordance with the policy.

Apparatus and method for directing a communication session to a communication device of a group of devices having a common registration identity

A method and system for addressing a unique device from an address book, the method having the steps of: receiving a message having a root token and a secondary token; checking whether the root token exists within the address book, if no, creating a record in the address book with the root and secondary token; and if yes, checking whether the secondary token exists within the address book, if yes, providing a representation of the unique device; and if no, storing the secondary token against the root token in the address book.

System and method for addressing a unique device from a common address book

Methods and systems for facilitating transfer of an active session from a first device to a second device associated with the same user. A network server is configured to enable the switching or swapping of an active session from one device to another device, where both devices are associated with a common user address. The switching or swapping is implemented with no or minimal effect on the active session or awareness of the remote party. The device switch may be performed in relation to any active session, including VoIP, video conferencing, or other media sessions.

Methods and systems for facilitating transfer of sessions between user devices

A method is provided for delivering the capabilities of user agents. The method includes a user agent sending a session initiation protocol (SIP) message containing a Contact Header containing a Push Resource Identifier feature tag containing at least one push resource.

Method for delivering device and server capabilities

A user equipment (UE) is disclosed. The UE comprises a processor configured to transmit a session initiation protocol (SIP) SUBSCRIBE method request that comprises at least one filter criteria used for selecting specific messages and selecting the information about the messages, where each of the messages is directed to a user identity associated with the UE.
