Abstract: Concepts and technologies are disclosed herein for a peer applications trust center. A trust client can execute on a client computer and a trust service can execute on a server computer to provide the peer applications trust center. The trust client or trust server can register applications. During registration, the trust server or the trust client can generate a public key or other identifier for identifying the registered application. If another application requests access to the registered application, the trust server or the trust client can determine if the request specifies a registered application by name. If the requestor is granted access to the application, the requestor can be issued a token. Tokens can be revoked, updated, replaced, or renewed for various purposes.

Abstract: Messages directed to a mobile device are selectively routed to message servers based upon the capabilities of a network to which the mobile device is connected. According to an illustrative method disclosed herein, a network connectivity server receives a network identifier from the mobile device, the network connectivity server receives a request for routing instructions for the message, and the network connectivity server determines if the network identified by the network identifier is capable of delivering the message. The network connectivity server then instructs the message server to route the message according to a standard delivery method for a message type of the message or to a message conversion server computer based upon the determination. The message conversion server computer converts the message into a new message type that the network is capable of delivering to the mobile device.

Abstract: Disclosed is a method for de-registering user equipment from a network in response to notification that the user equipment will cease using network services. An Interruption Service Manager (ISM) notifies the network to suspend services as the IMS network conditions or the user equipment conditions change. The ISM may also notify the user equipment to re-register onto the IMS core network when the connection is re-established.

Abstract: An apparatus and a method that enable private network providers to offer public network voicemail service. In the private network, a status indicator indicates the subscriber's availability to receive calls, and a controller outdials and/or issues signaling commands to the public network. A status register in the public network, being controllable by signaling commands, determines whether incoming calls are processed normally or routed to voicemail. When a call to the private network goes unanswered, the controller sets the public status register to route calls to the subscriber's public mailbox, and then establishes a link between the incoming call and the public voicemail. The public status register is reset either immediately after establishing the link or after call termination. When the private network subscriber desires to retrieve voicemail, the controller also sets the public status register to effects re-routing of incoming calls to public voicemail system during message retrieval.

Abstract: A method for facilitating the placement of emergency calls from a wireless telephone within a cellular, or other wireless, communication system is disclosed herein. A wireless telephone is configured to receive from a base station a local emergency number associated with the service area of the base station. During operation of the wireless telephone, each number dialed or otherwise entered in by a user is compared to the local emergency number. If the dialed number matches the local emergency number, an emergency call is initiated by the wireless telephone; otherwise, the wireless telephone initiates a standard telephone call in response to entry of the dialed number. The user interface of the wireless telephone may optionally provide an indication upon the placement of an emergency call.
