摘要:
A system and method for pushing a service book to a mobile device is provided. A service book includes a plurality of fields relating to a host service. At least one mobile device is identified that is to receive the service book. Wireless propagation information is provided that identifies an address for the mobile device to receive the service book. The service book is transmitted over a wireless network using the address for the mobile device, and is received by the mobile device.

A system and method for synchronizing data records between multiple database is provided. Each database includes data records that are modified to include at least one pair of synchronize parameters. In a two-database system including a first database and a second database, each data record is modified to include synchronization parameters for both the first and second databases. When an update is made to data record at one of the databases, an update message is transmitted to the other database including both synchronization parameters from the database where the update is made, along with the undated data record. An efficient master-slave configuration between the database then enables either database to resolve conflicts without further communications.
摘要:
A communication device includes a database. The database is configured to store data records to be synchronized with a host device and to store, for each record, a corresponding device synchronization parameter (DSP) and a corresponding host synchronization parameter (HSP). The DSP indicates a version number assigned to a current version, of the respective data record, as stored in the database of the device. The HSP indicates a version number assigned to a current version, of the same record, as stored in the host device.

The system and method scale to systems having more than two databases by modifying the data records in at least one of the databases to include a pair of synchronization parameters for each of the other databases to which it is being synchronized, and by providing a multi-level master-slave configuration. The system and method permits the ability to add and delete records and to securely communicate between all synchronized databases.

摘要:
Network selection techniques for use in a mobile device which is configured for voice and packet data communications are described. The mobile device performs a scanning operation to identify one or more communication networks, and consults a network selection list for selecting, in accordance with assigned priorities of the list, one of the identified networks. The mobile device also determines whether a packet data service interconnection to a home network via the selected network is available. If the interconnection to the home network via the selected network is determined to be available, then the mobile device operates with voice and packet data services in the selected network. Otherwise, if the interconnection to the home network via the selected network is determined to be unavailable, then the mobile device repeats the acts of consulting and determining for the next identified network in the list.
摘要:
A mobile communication device is adapted to provide voice communications with use of a voice service and data communications with use of a data service. The mobile device maintains a preferred network list as well as a service access list in its memory. The preferred network list has a listing of a plurality of networks with assigned priorities for network selection. The service access list has a listing of a plurality of networks that make the data service available to the mobile device. The mobile device performs a scanning operation for identifying one or more communication networks available in a coverage area of the mobile device. When a home network of the mobile device is unavailable in the coverage area, the mobile device consults the preferred network list and the service access list for identifying one of the networks identified by the scanning operation. The mobile device attempts to register for the data service via the identified network and, if successful, operates its wireless transceiver with the identified network to use the data service. If the attempt to register for the data service fails, the mobile device excludes the identified network from being listed in the service access list as making the data service available.

Reduced delays in data service offered by data-capable networks are provided. One illustrative method includes the steps of receiving and storing in memory a first timer value which is broadcasted by a wireless communication network for use in the mobile station; causing a request for data connectivity to be transmitted through the wireless network, and reattempting the request up to a plurality of times when data connectivity fails; after the one or more reattempted requests for data connectivity fail, activating a timer based on a second timer value which is less than the first timer value; and repeating the transmitting of requests for data connectivity after expiration of the timer.
