US 8165573 B2Abstract
In one embodiment, a scheme is disclosed for managing delivery of a Mobile-Terminated (MT) call via an IMS network, wherein the MT call is originated by a calling party towards a User Equipment (UE) device that is CS-attached. An IMS-capable network node is operable to associate the received call information with an IP Multimedia Routing Number (IMRN) and provide the call information and the IMRN via alternative signaling (e.g., USSD or SMS messaging) to the UE device. A Mobile-Originated (MO) call process is initiated by the UE device using the received IMRN as the destination number, which terminates at the network node. Upon verifying that the returned IMRN is valid, the network node bridges the access and remote legs to establish the end-to-end path for the MT call between the UE device and the calling party.
This nonprovisional patent application claims priority based upon the following prior U.S. provisional patent application(s): (i) �SYSTEM AND METHODS FOR MANAGING MT CALL USING ALTERNATIVE SIGNALLING,� Application No. 60/941,322, filed Jun. 1, 2007, in the name(s) of Adrian Buckley and Jan John-Luc Bakker; (ii) �SYSTEM AND METHODS FOR MANAGING MT CALL USING ALTERNATIVE SIGNALLING,� Application No. 60/942,949, filed Jun. 8, 2007, in the name(s) of Adrian Buckley and Jan John-Luc Bakker; and (iii) �SYSTEM AND METHODS FOR MANAGING MT CALL USING ALTERNATIVE SIGNALLING,� Application No. 60/943,115, filed Jun. 11, 2007, in the name(s) of Adrian Buckley and Jan John-Luc Bakker, which is (are) hereby incorporated by reference.
This application discloses subject matter that is related to the subject matter of the following U.S. patent application(s): (i) �SYSTEM AND METHOD FOR MANAGING MOBILE-TERMINATED (MT) CALLS IN IMS NETWORK ENVIRONMENT USING ALTERNATIVE SIGNALING�, application Ser. No. 12/126,974, filed May 26, 2008; and (ii) �MESSAGE GENERATION SYSTEM AND METHOD FOR MANAGING IMS SIGNALING OVER A CIRCUIT-SWITCHED NETWORK�, application Ser. No. 12/126,979, filed May 26, 2008, both of which are hereby incorporated by reference.
The present patent disclosure generally relates to call processing in communications networks. More particularly, and not by way of any limitation, the present patent disclosure is directed to a system and method for managing a Mobile-Terminated (MT) call in a network environment including a Circuit-Switched (CS) network and an IP Multimedia Subsystem (IMS) network.
Operators may offer services hosted on or through an IMS network to CS-attached devices, which allows for certain IMS-based services (including supplementary services) to be consumed by such devices. Whereas delivery of an MT call originated by a calling party towards a CS-attached device is being contemplated as one of the IMS-based services, various problems arise with respect to managing such an MT call, especially where multiple MT calls may be involved.
The present patent disclosure is broadly directed to a scheme for managing delivery of an MT call to a CS-attached UE device via an IMS Centralized Services (ICS) capable functionality. In one aspect, an embodiment is directed to a UE device operable in connection with an IMS network. The claimed embodiment comprises one or more of the following: a component configured to receive an alternative signaling (AS) message via a Circuit-Switched (CS) network domain; a component configured to determine that the AS message is for delivery of a Mobile-Terminated (MT) call to be terminated at the UE device; a component configured to store call information received in the AS message, the call information comprising at least an IMS Multimedia Routing Number (IMRN); and a component configured to initiate a Mobile-Originated (MO) call process towards a network node with the IMRN as a destination number, wherein the MO call process is operable to effectuate an access leg with the network node with respect to the MT call.
