  • Publication number: 20150271782
    Abstract: The invention is directed to reducing paging overhead in a network. An exemplary method comprises: determining whether a user equipment (UE) is substantially stationary, wherein the UE is located in a first network cell associated with a network; in response to determining the UE is substantially stationary, transmitting an indicator to the network; determining whether the UE moves from the first network cell to a second network cell; and in response to determining the UE moves from the first network cell to the second network cell, transmitting updated location information associated with the UE to the network.

  • Publication number: 20150195752
    Abstract: Embodiments of the invention are directed to systems, methods and computer program products for routing traffic in a packet data network (PDN). A method includes determining whether the mobile device has an active long-lived data traffic session over an original PDN connection between the mobile device and a first PDN gateway (P-GW); if the mobile device has an active long-lived data traffic session, then routing any new long-lived data traffic session over the original PDN connection; and if the mobile device does not have an active long-lived data traffic session, then routing any new long-lived data traffic session over a location-based PDN connection established based at least in part on a current location of the mobile device. In other words, the mobile device initiates and maintains all long-lived data sessions (for which service continuity is essential) to only one PDN connection.

  • Publication number: 20140032757
    Abstract: A method for controlling the access of at least one application, in an application entity, to at least one modem, in a modem entity, where the controlling is performed using a modem access information framework. The modem access information framework collects modem access information from the modem access interface based on activity of the at least one modem, and distributes the modem access information to any of the at least one application that is subscribing to the modem access information or requesting the modem access information from the modem access information framework.

  • Patent number: 8147327
    Abstract: A method for updating a game session comprises detecting a game event during a game session, sending an update request to a game data object server responsive to the game event, receiving a game data object from the game data server responsive to the update request, and updating the game session with the game data object. The update request preferably includes an event identifier associated with the game event and the identity of at least one game participant. Based on the player and event identified in the update request, the game data object server selects a corresponding game data object and sends the game data object to each of the players.

  • Publication number: 20110191427
    Abstract: A communication method for sending a message to an addressee using a first and second communication device of a user is disclosed. The method includes steps of, by the second communication device, determining that a message is to be sent from the user to the addressee, and sending, to the first communication device, at least part of the message; and steps of, by the first communication device, receiving, from the second communication device, the at least part of the message, and sending, to the addressee, the message with information identifying the first communication device as sender of the message. A communication method for receiving a message and replying thereto using a first and second communication device of a user is also disclosed.

  • Patent number: 7774478
    Abstract: A method for scheduling another time for a communication session when a called party is presently unable or unwilling to accept an incoming call. A first user's communications device receives a request for a communication session from a second user's communications device. Upon failure to accept the request, a server automatically forms a calendar data object, such as in response to receipt of a scheduling trigger message from the first communications device that includes an indication of the failure to accept and an identifier of the second user. The calendar data object includes scheduling information indicating, explicitly and/or implicitly, future time(s) when the first user is available. The calendar data object is sent to either one of the devices, and a time is selected. The server then notifies the other device of the selected time. Corresponding devices are also described.
