Abstract: The graphical display capability and the digital data communication capability of wireless mobile handsets are used to present a customized directory of a called enterprise on the display screen of the mobile handset to allow the caller to identify their desired call destination by name. A directory database stores directory information for each call destination of the enterprise. An incoming call to an enterprise IVR unit causes a directory manager to generate a request for user data which is forwarded to the mobile handset via a gateway. The mobile handset opens a data connection and forwards the user data to the directory manager. The directory manager evaluates at least one access rule in response to the user data to select relevant directory information from the directory database, and the directory manager forwards the relevant directory information to the mobile handset for display. Then the user of the mobile handset selects a call destination based on the displayed directory information.

Abstract: An apparatus may comprise a location-aware application, a first location detector, and a data storage device. The storage device may contain service-access-point (SAP) data that identifies a first SAP through which the apparatus may access a second location detector. The first detector may obtain data from the second detector via the first SAP and use the obtained data to determine a location of the apparatus. This determined location may be provided to the location-aware application. The data storage may include program instructions for modifying the SAP data such that the SAP data identifies a second SAP through which the apparatus may access a third location detector. The first detector may obtain data from the third detector via the second SAP and then use the obtained data to determine a location of the apparatus. This determined location may be provided to another location-aware application that is executable at the apparatus.

Abstract: Directory information is displayed on a mobile handset of a user when a dialed telephone number is a directory-capable number. A directory processor receives the dialed telephone number and checks whether the dialed telephone number appears in a database of directory-capable telephone numbers. A gateway pushes a data message including a data address of a directory server to the mobile handset. The directory server stores directory information for a plurality of call destinations with respective destination identifiers and respective access rules. A client application in the mobile handset responds to the data message. The directory server identifies relevant directory information based on the dialed telephone number and transmits it to the client application via the data call. The client application displays the relevant directory information and the user selects a call destination.

Abstract: Disclosed is a method and system in which an intermediary is provided within a communication path through which a message is transmitted from its originator to a client device, and the intermediary operates to insert into the message a target port number based at least in part on the originator of the message. In a scenario where the message originator provided or is otherwise associated with a given application group on the client device, the intermediary may thus modify the message to have the message designate as target port number the port number that the client device associates with the application group. Ultimately, when the client device receives the message, the client device would read the target port number and responsively route the message to the appropriate application or application group.

Abstract: Exemplary methods and systems may provide a soft-inactivity notification during a VoIP call, which according to an exemplary embodiment involves a SIP session and packet-data communications between participants in the VoIP call. The method comprises (a) detecting that packet-data communications in the VoIP call have been interrupted; (b) in response to determining that the packet-data communications have been interrupted, making a determination as to whether or not the SIP session is active; (c) if the SIP session is active, then initiating a soft-inactivity notification procedure; and (d) otherwise, if the SIP session is inactive, refraining from initiating the soft-inactivity notification procedure. The soft-inactivity notification thus notifies a user that while the call has been interrupted, the call may be re-established without requiring the user to reconnect.
