Abstract: The present invention provides a method of operating a communication portal. One embodiment of the method includes accessing, at the communication portal, an alert message addressed to a group registered to receive an alert service. The method also includes generating user identifiers corresponding to users that are registered to the group. The user identifiers are assigned to the users for use within the communication portal. The method further includes transmitting the alert message from the communication portal to the users indicated by the user identifiers.

Abstract: A system comprising a first network element, a second network element and a communication device. The first network element is communicatively coupled to the second network element and the communication device. The communication device sends multimedia session information to the first network element. The first network element analyzes the multimedia session information for urgent emergency circumstances. The first network element forwards the multimedia session information to a destination on the second network element if urgent emergency circumstances are found in the multimedia session information.

Abstract: Gateway systems and methods are disclosed for allowing for communication between a real world environment and a virtual world environment. A gateway system in one embodiment is implemented between the virtual world environment and the real world environment. For a session being initiated from a real world user to a virtual world user, the gateway system receives a signaling message from the real world user to initiate the session with the virtual world user, and processes the signaling message to identify a virtual world identifier assigned to the virtual world user. The gateway system converts the signaling message to a communication request message in a protocol used in the virtual world environment, and transmits the communication request message to the virtual world user to establish the session. When the session is established, the virtual world user and the real world user may communicate via voice and/or data.

Abstract: Communication networks and methods are disclosed that provide a supplemental content service. The supplemental content service provides synchronized supplemental content, such as media clips, to a user over a communication network (e.g., a mobile wireless network). A content provider offering a primary content stream (e.g., a television program) broadcasts the primary content stream to a content receiving device (e.g., a television) of the user. The content provider also generates supplemental content that is an enhancement to the primary content stream. If the user subscribes to the supplemental content service, then the communication network provides the supplemental content to the user through a communication device (e.g., a mobile phone) that is synchronized with the primary content stream. The user can then experience the supplemental content over the communication device at the same time as experiencing the primary content stream over the content receiving device.
