| 20080220800 | DATA-CAPABLE NETWORK PRIORITIZATION WITH REDUCED DELAYS IN DATA SERVICE - In one illustrative method, a periodic location update timer value is broadcasted by a wireless communication network and received and stored in memory of a mobile station. A request for data service is transmitted by the mobile station to a wireless communication network, and the request is reattempted at least one time in response to identifying a rejection of the request. If the request for the data service is accepted in response to the request, the mobile station operates in the wireless communication network using the data service. On the other hand, if the request for the data service is not accepted, the mobile station is set in a data service deregistered state. A timer is initialized with an initial value that is less than the periodic location update timer value and started. In response to an expiration of the timer, the mobile station repeats the transmission of the request for the data service and any reattempts in response to any rejections of the request. If the periodic location update timer value is less than the initial value, however, the timer is initialized with the periodic location update timer value. | 09-11-2008 |

| 20080270486 | SYSTEM AND METHOD FOR SYNCHRONIZING DATA RECORDS BETWEEN MULTIPLE DATABASES - A system and method for synchronizing data records between multiple databases is provided. Each database includes data records that are modified to include at least one pair of synchronization 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 a 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 updated data record. An efficient master-slave configuration between the databases then enables either database to resolve conflicts without further communications. 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. | 10-30-2008 |
| 20080287125 | Methods And Apparatus For Selecting A Communication Network - 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. | 11-20-2008 |
| 20090034506 | Data Burst Communication Techniques For Use In Increasing Data Throughput To Mobile Communication Devices - Methods and apparatus for use in increasing data throughput to mobile stations in a wireless communication network, where data is communicated between mobile stations and the wireless network in a plurality of data bursts within time slots assigned to the mobile station. One illustrative method includes the acts of receiving, through a wireless transceiver, data in a time slot W; tuning the wireless transceiver, during a first portion of a time slot X which follows the time slot W, for transmission; reading transmit data from a transmit data queue and encoding the transmit data in a data burst in accordance with a data burst format; and causing the encoded transmit data to be transmitted in the data burst during a second portion of the time slot X. The data burst may be formatted in accordance with a predefined data burst format of the wireless network and merely shifted in time, or the data burst may be formatted in accordance with a reduced-size data burst format. When such alternate data burst technique is utilized, extra available time remains to tune the wireless transceiver from receive to transmit mode, or transmit to receive mode. Thus, an additional downlink time slot(s) per data frame may be allocated to the mobile station for increased data throughput, where at least one uplink time slot per data frame is utilized for data transmission. | 02-05-2009 |

| 20100020697 | METHOD AND SYSTEM FOR MONITORING THE HEALTH OF WIRELESS TELECOMMUNICATION NETWORKS - 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. | 01-28-2010 |
