  • Patent number: 10348781
    Abstract: A method and apparatus for enabling registration of an Aggregate End Point (AEP) device that is incapable of supporting a Session Initiation Protocol (SIP) based Internet Protocol Multimedia Subsystem (IMS) registration are disclosed. The method performs a static registration of the AEP device in a plurality of network elements associated with an Internet Protocol Multimedia Subsystem (IMS) network by provisioning. The method then processes an originating call request or a terminating call request associated with the AEP device using the static registration.
    Type: Grant
    Filed: June 19, 2017
    Date of Patent: July 9, 2019
    Assignee: AT&T Intellectual Property I, L.P.

  • Publication number: 20110161519
    Abstract: A method and an apparatus for providing a transit service in a communications network are disclosed. For example, the method receives a session request by a routing device, where the session request is directed towards a user endpoint device that accesses one or more services via the aggregate endpoint device, and interrogates a Home Subscriber Server (HSS) for domain information of the aggregate endpoint device. The method determines if the domain information of the aggregate endpoint device is associated with a transit function, and routes the session request to the transit function for completion, if the domain information of the aggregate endpoint device is associated with the transit function.
