  • Patent number: 11032693
    Abstract: Techniques for use by a mobile device configured to operate in a wireless network for the communication of data messages with a server are described. When the mobile device does not have an open session with the server, the mobile device receives from a service node via the wireless network a message which informs the mobile device that a data message has arrived at the server and needs to be retrieved. The message includes an identifier which identifies the data message at the server. In response to opening an application at the mobile device, the mobile device communicates directly with the server via the wireless network for retrieving the data message. This involves commencing an open session with the server, sending to the server a command for retrieving the data message, and receiving from the server the data message in response to sending the command. The mobile device may use the identifier for retrieving the data message from the server.

  • Patent number: 8516055
    Abstract: A system and method for redirecting data from a host system (or messaging server) to one or more mobile data communication devices via a wireless packet data network is provided in which the wireless packet data network dynamically assigns addresses to the one or more mobile data communication devices on an as-needed basis. A redirector application operating at the host system is configured by each user to continuously redirect certain data to the wireless packet data network, as the data is received (or otherwise altered) at the host system. Two methods are provided for communicating the redirected data from the network to the mobile device. In a first method, the mobile device is configured to periodically contact a store-and-forward server within the wireless network, which, when contacted, assigns a network address to the mobile device and then transmits the stored, redirected data to the mobile device.

  • Patent number: 8320900
    Abstract: In one illustrative example, a mobile device receives from a relay services node an enable message which indicates a pending data message to be retrieved from a host service. The pending data message may comprise a body of text. Subsequent to the receiving of the enable message, a messaging application is opened at the mobile device. In response to the opening of the messaging application, the mobile device communicates directly with the host service without use of the relay services node, for retrieving the pending data message from the host service via a wireless network.
