Abstract: A router system maintains a status of a wireless device of either available or unavailable. The status of available may be indicative of the wireless device being in-coverage with a wireless network, whereas the status of unavailable may be indicative of the wireless device being out-of-coverage with the wireless network. The router system is adapted to receive, from a host service, a user data message that is addressed to an address of the wireless device. The user data message has a user data payload and one or more request parameters, where the one or more request parameters instruct the router system on whether to return at least a portion of the user data message to the host service when the device status is unavailable. In response to the user data message being received at the router system when the device status is available, the router system delivers the user data message to the wireless device via the wireless network.

Abstract: Two or more connection profiles stored in a wireless device are partitioned into two or more groups, each group having a different number of sleep intervals associated therewith. The number of sleep intervals associated with a particular group determines a wait between subsequent scans for wireless local area networks matching any profile in that particular group. One or more factors may be taken into consideration when determining how to partition the profiles into groups, including, for example, a connectivity history of the wireless device.

Abstract: A system and method of providing a clock signal to a navigation satellite receiver in a device is disclosed. A clock signal generated by a voltage controlled temperature compensated crystal oscillator (VCTCXO) in a cellular engine of the same device is appropriated to clock a numerically controlled oscillator (NCO) programmed to generate an adjusted clock signal suitable for use in receiving signals from navigation satellites and to heterodyne them down to baseband or an intermediate frequency for processing. Preferably, if the cellular engine has an automatic frequency control (AFC) module for adjusting the voltage control input to the VCTCXO to compensate for a change in the operating environment of the cellular engine, the AFC module modifies the control word in the NCO to counteract such adjustment so that the adjusted clock signal provided to the navigation satellite receiver is not unduly impacted.

Abstract: Apparatus and methods for managing data used by mobile devices. Data can be retrieved from a second computing device (e.g. a server) where it is stored on a storage medium (e.g. a disk). A subset of the data of a data record stored in the storage medium, or one or more pointers to the data of a data record stored on the storage medium is stored in a memory of the mobile device so that it is not necessary to store a given data record in its entirety in the memory of the mobile device.

Abstract: Resource bundles are provided that contain localized resources that a handheld device can use to adapt an application to the current locale of the hand-held electronic device. The resource bundles can be stored in a remotely-located server and downloaded over a network to the hand-held electronic device on request. Alternatively, a hand-held device can store resource bundles for multiple locales and choose a resource bundle that is appropriate for its current locale. A resource bundle can be used to allow a hand-held device to automatically adapt an application to the current locale such as by identifying an entered character sequence that matches a predetermined sequence associated with the current locale of the hand-held device, choosing an article for use with a word that is grammatically correct for the language associated with the current locale, and automatically replacing the character sequence with the article.
