20100211993 | METHOD AND APPARATUS FOR PACKET DATA SERVICE DISCOVERY - A method and device for packet data service discovery are described. A mobile device memory stores a packet data services blacklist and a historical blacklist. The packet data services blacklist identifies wireless networks that do not provide packet data services to the mobile device. The packet data services blacklist is based on previous packet data service authentication rejections, is distinct from a voice services blacklist, and is updated in response to newly received packet data service authentication information. The historical blacklist is distinct from the packet data services blacklist and the voice services blacklist. The historical blacklist identifies wireless networks that are no longer in the packet data services blacklist and were once in the packet data services blacklist within a particular time period. No advance knowledge of data services roaming agreements is required, and unnecessary network access can be avoided, which in turn saves network resources and capacity. | 08-19-2010 |

The system and method further includes selectively starting and stopping the serving of the wireless device by the push server during a voice call. | 12-09-2010 |
20110026489 | OPTIMIZED DATA RECONNECT - A method of optimizing reconnection of a point to point protocol link layer in a mobile device comprising the steps of: monitoring whether the mobile device has entered a new zone; starting a stabilization period when the mobile device enters a new zone; checking whether the mobile device enters a different zone during the stabilization period; if the mobile device enters a different zone during the stabilization period, restarting the stabilization period and performing the checking step; and if the mobile device does not enter a new zone during the stabilization period, determining whether the mobile device is in a new zone, reconnecting to the new zone if the mobile device is in the new zone, and otherwise performing no reconnection. | 02-03-2011 |
20110058476 | Methods And Apparatus For Controlling Wireless Network Operations Associated With A Flow Control Process - Techniques for controlling wireless network operations associated with a flow control process of a wireless network involving a data session established between a mobile station and a service node. The network processor examines quality of service (QoS) data associated with the data session. The network processor causes the flow control process to be bypassed for the mobile station based on the QoS data indicating that the data session is associated with a predetermined traffic class (e.g. background traffic class). This serves to prohibit the flow control process from stopping the flow of data packets in the data session without terminating the data session based on detection of an out-of-coverage condition. Otherwise, the network processor allows the flow control process to be performed for the mobile station based on the QoS data indicating that the data session is not associated with the predetermined traffic class. | 03-10-2011 |
