Patent number: 7747691Abstract: A system and method for reducing congestion in wireless communication systems is provided. An unsolicited message reduction system includes a message detector and an all points bulletin (APB) generator. The message detector applies predefined filtering rules to identify and act upon unsolicited email messages to reduce the total number of transmissions in the wireless communication system. The filtering rules include global and user rules, with the global rules normally having precedence over user rules. The APB generator allows messages to be sent wireless mobile communication devices through direct wireless messages instead of through email messages.Type: GrantFiled: October 9, 2006Date of Patent: June 29, 2010Assignee: Research In MotionInventors: William D. Castell, Allan D. Lewis, Tabitha K. Ferguson, Bill Yuan, Ian M. Patterson

Publication number: 20100122325Abstract: Methods and apparatus of a wireless portable communication device for maintaining appropriate authentication credentials for accessing a data application maintained in a service network are provided. A default access point name (APN) or network access identifier (NAI) is maintained in memory of the wireless device. The wireless device submits, via a default wireless network, the default APN or NAI for establishing a data session in the default wireless network. The wireless device is then able to receive, in the data session via the default wireless network, a message service using the common data application maintained in the service network. In response to a change in service subscription for the wireless device, the wireless device receives, via a current cellular network, a current APN or NAI and stores it in its memory. The wireless device then submits, via the current wireless network, the current APN or NAI for establishing a data session in the current wireless network.Type: ApplicationFiled: November 30, 2009Publication date: May 13, 2010Applicant: RESEARCH IN MOTION LIMITEDInventors: Thomas Leonard Trevor Plestid, Allan D.

Publication number: 20100020697Abstract: A method and system for monitoring the health of a wireless telecommunication network. Network health is monitored without placing an administrative burden on the carrier network itself, instead, this burden is placed on components that lie outside the carrier network and pass communications through it. The data service provider infrastructure sends a request to a mobile device, asking that it return data regarding its location. The carrier networks handling the request insert location information into the packet that is sent to the mobile device, but this information is not sent to the data service provider infrastructure itself. The mobile device harvests this location information from the packets it receives and inserts it in a response packet that finds its way back to the data service provider infrastructure. The data service provider infrastructure is able to collate this location data and to analyze it, determining the carrier network's health.Type: ApplicationFiled: October 6, 2009Publication date: January 28, 2010Applicant: RESEARCH IN MOTION LIMITEDInventors: ALLAN D.

Patent number: 7366093Abstract: One illustrative method of reducing undeliverable server-initiated IP traffic within a wireless network (21) includes the steps of identifying that a data connection (e.g. a Packet Data Protocol or PDP Context) for communicating server-initiated IP messages from a host server (22 or 26) to a mobile station (10) has been lost or terminated; causing a notification message having a destination address corresponding to the host server (22 or 26) to be produced based on identifying that the data connection has been lost or terminated; and causing the notification message to be sent to the host server (22 or 26). The notification message may cause the host server (22 or 26) to at least temporarily refrain from communicating and/or to queue server-initiated IP messages (10) intended for the mobile station (10). The notification message may be formatted and communicated based on an existing protocol, such as Internet Control Message Protocol (ICMP), or any other suitable protocol.Type: GrantFiled: May 5, 2004Date of Patent: April 29, 2008Assignee: Research In Motion LimitedInventors: Nicholas P.

Publication number: 20040136358Abstract: 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.Type: ApplicationFiled: March 19, 2003Publication date: July 15, 2004Inventors: Hugh Hind, Michael Knowles, Noushad Naqvi, David Bajar, Ian M.
