Abstract:
A method and apparatus for selectively redirecting session control for a user equipment in a telecommunication system include: a home server (108), a proxy server (204, 206), and a user equipment (202) for transmitting a breakout request (208, 210) to the proxy server (204, 206) to break out of an initial service route that includes the home server (108) to a direct service route that bypasses the home server (108).
Abstract:
A system and method for call origination by an application server in an internet protocol multimedia core network subsystem includes a first step of providing a public user identity for a user. A next step includes storing a service parameter in a service profile of the user, the service parameter indicating whether to allow/disallow the application server to initiate call requests on behalf of the public user identity. If the service parameter allows the application server to initiate call requests, the system unblocks calls originated by the application server on behalf of the user. If the service parameter disallows the application server to initiate call requests, the system blocks calls originated by the application server on behalf of the user.
Abstract:
A network and method of routing a call between communication networks includes a first step of establishing a reverse ENUM DNS server containing a table of NAPTR records that associate E.164 telephone numbers with identifiers. A next step includes routing a call from an originating PSTN system to a first gateway. A next step includes sending an ENUM query containing an E.164 telephone number to an ENUM DNS server, which returns an identifier associated with the E.164 telephone number. A next step includes routing the call to a second gateway. A next step includes launching a reverse ENUM query containing the identifier to the reverse ENUM DNS server, which looks up an E.164 telephone number associated with the identifier, and returns it to the second gateway. A next step includes routing the call from the second gateway to the returned E.164 telephone number in the terminating PSTN system.

Abstract:
A method for transferring an instant messaging and presence (IMP) session from a source device (101) to a target device (103) includes the steps of registering (130) the target device with an IMP server (105), sending (150, 152) historical IMP session information from the source device to the target device, and subscribing (170) the target device to the IMP server. The target device (103) initiates the transfer of historical IMP session information (thus, we refer to it as a "grab" or "grab transfer"), and the target device (103) may optionally instruct the source device (101) to de-register (160) from the IMP server (105). Related methods for the target device and the source device are disclosed as well as an electronic device operable to be either a source device or a target device.
