Abstract: Wireless devices and methods are provided for performing mobile discovery of an active data subscription. This involves a wireless device attempting to register using an APN that is one of a CDMA-centric APN and a GSM-centric APN. If that attempt fails, then the wireless device attempts to register using an APN that is the other of the CDMA-centric APN and the GSM-centric APN. In some cases the first APN attempted is always the CDMA-centric APN; in some cases the first APN attempted is a previously successfully used APN. For wireless devices with a data roaming enable/disable mechanism, the method can be executed while data roaming is disabled such that when data roaming is enabled, the proper APN to use will have been previously identified.

Abstract: A method, system and apparatus for dynamically modifying the quality of service provided to a mobile communication device. The method includes the steps of establishing a secure tunnel between the mobile communication device and a remote network through a wireless network; communicating through the secure tunnel at a first quality of service; determining that a second quality of service, higher or lower than the first quality of service, is more appropriate to the communication type, and requesting, from the wireless network, the second quality of service.

Abstract: Devices and methods are provided for configuring multi-mode mobile stations. When the number of data sessions available to a multi-mode mobile station changes, the multi-mode mobile station sends information to configuration server sufficient to determine the capability of the network and identify the multi-mode mobile station. The number of data sessions available to a multi-mode mobile station may change for example due to the multi-mode mobile entering a network, changing radio access technologies (RAT) used in the network or changing radio network controllers having the same or a different respective number of data sessions. A configuration server receives the information sent by the multi-mode mobile station and selects configuration information for configuring the multi-mode mobile station to support services/applications that are subscribed to by a user of the multi-mode mobile station.

Abstract: An embodiment provides a method for communicating location-based information between an application server and a mobile device in response to an information query, the mobile device and the application server communicating via a communication network, the method comprising the steps of: initially transmitting a subset of the location-based information to the mobile device in response to the information query; transmitting further subsets of the location-based information as required; and pre-caching a predefined amount of location-based information at the device in response to a pre-cache trigger notification, the pre-cache trigger notification being generated when it is determined that the mobile device may lose contact with the communication network.

Abstract: A method and apparatus to restore always on connectivity to user equipment, the method having the steps of: monitoring whether the user equipment has transitioned to a network that supports concurrent voice and data; performing, upon the monitoring step detecting the transition, a routing area update; checking whether the user equipment was in a voice call at the time of the transition, and if yes, sending a data packet to the network.

Abstract: A method and apparatus for automatically sending a data message from a mobile device to at least one recipient during or soon after an emergency voice call, the method having the steps of: determining whether the data message can be sent over the network during the emergency voice call, and if yes, creating and sending the data message; and if no, waiting until either the mobile device connects to a new network, wherein the method proceeds back to said determining step, or until the voice call has ended and then creating and sending the data message.

Abstract: In one embodiment, a method is provided for evaluating reliability of a communications link between a sender and a receiver in a wireless packet data network.
