Software Defined Networking (SDN) is used in IMS in order to provide a mechanism to forward (Internet Protocol) IP packets and provide a simplified solution to the complex signaling path of IMS according to directives from an SDN Controller. SDN is used in at least three particular scenarios. In the first scenario, communications are simplified using SDN directed signaling disaggregation. In the second scenario, SDN is used to direct media function chaining. In the third scenario, the system can be used as an SDN based media relay.

System and method for using software defined networking in internet protocol multimedia subsystems

A method and system for centralized control of user devices is disclosed. The method for centralized control of user devices via universal IP services registrar includes receiving a request to register a user device for a plurality of services, registering the user device for the plurality of services by creating a user settings profile for the user for each of the plurality of services, receiving data from the plurality of registered services, and transmitting received data to the user device in accordance with the user profile.

Centralized control of user devices via universal IP services registrar/hub

A method including receiving a request for a communication session with a recipient having a recipient identifier; querying a subscription database for subscription information for the recipient; receiving, from the subscription database, the subscription information for the recipient; selecting one of a plurality of service processing elements based on the subscription information for the recipient; and sending the communication session to the one of the service processing elements based on subscription information received from the subscription database.

Method and system for routing of session-based services

A method includes receiving, at first communication service provider equipment, a request to initiate a session between the first device and the second device. The second device associated with a particular user of a multimedia service provided by second communication service provider equipment. The first device has access to a particular application to access the multimedia service from the second communication service provider equipment. The method further includes sending a message including a call invitation to the second device to initiate the session. The call invitation includes location data related to a connection between the second device and the second communication service provider equipment for transfer of the particular application from the second communication service provider to the second device.

Session initiation for multimedia services

A method and an apparatus for processing a call to an aggregate endpoint device over a network are disclosed. For example, the method receives a session request by a Serving-Call Session Control Function (S-CSCF), wherein a route header for the session request comprises an aggregate endpoint identifier, and interacts with an application server to receive a Public User Identity (PUID) of the aggregate endpoint device in accordance with the aggregate endpoint identifier. The method performs a termination processing for the session request using the PUID of the aggregate endpoint device, and forwards the session request towards the aggregate endpoint device.

Method and apparatus for processing a call to an aggregate endpoint device

In one embodiment, the present invention is a method and apparatus for dynamic location-based message notification. In one embodiment, a method for providing alerts to a computing device includes identifying, via a set of location-specific computing resources, a current location of the computing device and sending at least one alert to the computing device, based on the current location.

Method and apparatus for dynamic location-based message notification

Disclosed are a network-based device, method and computer-readable medium for operating an IP Multimedia Subsystem (IMS) to provide registration review. The method embodiment includes tracking and storing all current registrations for each user in an IMS system, receiving a request from a user for a status of the user's current registrations and presenting, in response to the request, the current status of current registrations for the user.
