| 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 |

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 |
| 20080305763 | Methods And Apparatus For Use In Processing Disconnected Emergency Calls And Other Communications Involving Mobile Communication Devices And The Remote Monitoring Thereof - Methods and apparatus for use in processing disconnected emergency calls and other communications involving mobile communication devices, as well as the remote monitoring of such mobile communication devices, are disclosed. In one illustrative example, an emergency call with a public safety answering point entity is established by a mobile communication device via a wireless communication network. If the emergency call is disconnected, the mobile device monitors to receive an incoming call message for a continued emergency call from the public safety answering point entity.

Specifically, the mobile device operates to set and run a timer and, in response to an expiration of the timer, the mobile device sends, to a gateway controller via the RAN, a service connection request for a service connection with a core network of a home PLMN of the mobile device. If the service connection request is accepted, the mobile device operates to establish and maintain, via the GAN, a service connection with the core network of the home PLMN for communications. If this service connection request is not accepted, however, the mobile device operates to select an alternative visited PLMN from a preferred list of visited networks if the alternative visited PLMN has a higher priority in the list than the visited PLMN. In this case, the mobile device sends to a (gateway controller a service connection request for a service connection with a core network of the alternative visited PLMN. | 01-01-2009 |
