Abstract: The present invention provides a Cable Gateway for interfacing packet cable networks with Internet Protocol (IP) Multimedia Subsystems (IMS). The Cable Gateway includes an Embedded Multimedia Terminal Adaptor (E-MTA) Normalization function that includes translation software that normalizes E-MTA interfaces to appear to IMS as SIP user equipment and performs initialization, call signaling, registration, authentication and security. The Cable Gateway also includes a CMSS/Mw Normalization function that interworks calls going between the IMS and a Remote CMS and a Gate Controller function that implements signaling interfaces to a CMTS and allows the E-MTA Normalization function and the CMSS/Mw Normalization function to interact with the CMTS and normalizes call-flow protocols.

Abstract: This invention relates to methods and apparatus for securing communications between an open multimedia network and a trusted multimedia network. A multimedia boundary controller controls the communications between the two networks in order to intercept corrupting data such as viruses. The boundary controller contains an open network security engine for providing normal security and a trusted network security engine for implementing special software to provide additional protection. The unit is controlled by a secure processing unit which can prevent unwanted information from getting into the trusted network security engine and the trusted multimedia network. The secure processing unit communicates with a manufacturer of security software over the open network using encrypted messages.

Abstract: A authentication device of an apparatus in one example authenticates a computing device, in communication with the authentication device, through employment of a determination that a current location of the authentication device matches an initial location of the authentication device.

Abstract: The home cell system provides unified cellular service and wire-line service with a single Directory Number assigned to the subscriber's telephone station set and serves to provide a connection to the cellular network via the subscriber's local wire-line (POTS line) connection to the local wire-line telephone network (PSTN). The home cell system extends the capabilities of the cellular network allowing cellular-like service to be provided at wire-line access points, including standard analog or ISDN telephones, packet phones, soft phones, smart analog phones and ISDN phones. The wireless service provider provides telecommunication features to wire-line customers, such as handset mobility and service roaming. The present home cell system presents the wire-line telephones and wireless telephones, using a wire-line access point, to the cellular network as if they were cellular telephones.
