    摘要: A communication network is described that allows legacy devices to access an IMS network. The communication network includes a switching system, an IMS network, and a non-IMS network. The switching system includes a subscriber database that is pre-provisioned with identities of IMS subscribers using legacy devices. When in operation, a calling party places a call through a legacy device. The switching system receives the call and accesses the subscriber database based on a calling party identifier (e.g., a phone number, URL, etc) to determine if the calling party is an IMS subscriber. If the calling party is an IMS subscriber, then the switching system routes the call to the IMS network. If the calling party is not an IMS subscriber, then the switching system routes the call to the non-IMS network.

    摘要: IMS networks and methods are disclosed for securing media streams for IMS sessions. A CSCF of an IMS network receives a registration message, such as a SIP Register message, from user equipment (UE) of an IMS subscriber indicating whether the UE supports media security. The CSCF then forwards a registration message, such as a Diameter MAR, to a subscriber database that includes a header parameter also indicating that the UE supports media security. A media security system generates media security information (e.g., algorithms, keys, etc), and the subscriber database transmits a response message, such as a Diameter MAA, to the CSCF that includes a header parameter for the media security information. The CSCF transmits a response message, such as a SIP 200 OK message, to the UE that includes a header parameter for the media security information. The UE may use the media security information to secure media streams.

    摘要: The present invention provides a method for providing multimedia services. The method includes receiving, at an application server, a request for at least one multimedia service from a first end-user device and determining whether said at least one multimedia service is provided by a second end user device. The method also includes providing a request for the at least one multimedia service to the second end user device in response to determining that the at least one multimedia service is provided by the second end-user device.
