Abstract:
A method and an apparatus for providing mobility for a Voice over Internet Protocol Service (VoIP) provided on packet networks are disclosed. For example, the method receives a register request from a user endpoint device and retrieves an Access Point-address parameter from a contact header in the register request. The method then determines a physical location of an access point device in accordance with the Access Point-address parameter and updates location information for the user endpoint device in accordance with the physical location of the access point device.
Abstract:
Example systems and methods to manage location information for emergency services support of an internet protocol (“IP”) communication device are disclosed. A disclosed example method involves determining a geographic location change status associated with the IP device. A message is then forwarded to the IP device based on the geographic location change status requesting a user to confirm whether a registered geographic location associated with the IP device is a current geographic location of the IP device.
Abstract:
A system that incorporates teachings of the present disclosure may include, for example, a network element operably couplable to an Internet Protocol Multimedia Subsystem network where the network element has a controller to receive an SIP request associated with a call, determine whether the SIP request comprises an identifier associated with an Emergency Call Session Control Function (E-CSCF) where the identifier was added to the SIP request by the E-CSCF, and provide the call to an emergency network when the identifier is associated with the E-CSCF. Other embodiments are disclosed.
Abstract:
A system for deploying Voice over Internet Protocol (VoIP) services is provided. A system that incorporates teachings of the present disclosure may include, for example, a Call Session Control Function (CSCF) having a controller element to receive a Session Initiation Protocol (SIP)message from an originating communication device requesting communications with a terminating communication device, and establish an Internet Protocol (IP) connection between the originating communication device and an advertisement media system to present at the originating communication device an advertisement message that replaces a ringback tone associated with the terminating communication device. Additional embodiments are disclosed.
Abstract:
Network-based methods and systems transfer caller ID information from a telephony network to an IPTV network. Embodiments integrate service provisioning, subscriber account and policy information between telephony services and IP-based television services. Voice call signaling may be intercepted to retrieve caller ID, caller name information, and other call management information, at the call server in the network to deliver an appropriate notification message to the IP-based TV network at its notification server, which in turn sends a message notification to the called party's TV screen. Call log information may also be retrieved and displayed. SIP call forking and IP multimedia subsystem approaches are described.
Abstract:
A system that incorporates teachings of the present disclosure may include, for example, a server having a controller to adjust a call processing logic for Session Initiated Protocol to Integrated Services Digital Network User Part (ISUP) calls based at least in part on interworking profiles assigned to ISUP trunk groups supporting the calls. Additional embodiments are disclosed.
Abstract:
A system that incorporates teachings of the present disclosure may include, for example, a Home Subscriber Server having a processor adapted to receive from a Serving CSCF (S-CSCF) device a request for a subscription profile of a communication device to register the communication device, to detect from the request that the communication device is registered with a primary communication resource and that the communication device is to be registered with the S-CSCF device as a secondary communication resource, and to provide the S-CSCF device the subscription profile without de-registering the communication device from the primary communication resource and without directing the S-CSCF device to the primary communication resource. Other embodiments are disclosed.
Abstract:
A system that incorporates teachings of the subject disclosure may include, for example, a home subscriber server having a memory coupled to a processor. The processor can be configured to store a first identity of a first communication device registered with a primary communication resource and a secondary communication resource, receive a request associated with a registration request initiated by a second communication device, detect that a second identity of the second communication device matches the first identity of the first communication device, and direct a registration of the second communication device with at least one of the primary communication resource or the secondary communication resource responsive to the detected match. Other embodiments are disclosed.

Abstract:
A method and apparatus for managing an overload condition in a network are disclosed. For example, the method monitors the network for a traffic overload condition, and determines whether a more severe traffic overload condition or a less severe traffic overload condition is detected by using a network monitor and controller. The method then selects using a network monitor and controller agent in response to a command from the network monitor and controller, a different bandwidth preservation scheme if the more severe traffic overload condition or the less severe traffic overload condition is detected, wherein the different bandwidth preservation scheme is based on a selection of a codec type and is applied to a portion of the traffic.
