The mobile station may include an inactivity timer estimate and may be used to receive the starting value estimate and set the inactivity timer estimate to the starting value estimate. The mobile station may also be used to reset the inactivity timer estimate to the starting value estimate when the mobile station communicates with the APN. | 10-30-2008 |
20080293407 | Wireless Device and Method for Determining Which APN to Use - Wireless devices and methods are provided for performing mobile discovery of an active data subscription. This involves a wireless device attempting to register using an APN that is one of a CDMA-centric APN and a GSM-centric APN. If that attempt fails, then the wireless device attempts to register using an APN that is the other of the CDMA-centric APN and the GSM-centric APN. In some cases the first APN attempted is always the CDMA-centric APN; in some cases the first APN attempted is a previously successfully used APN. For wireless devices with a data roaming enable/disable mechanism, the method can be executed while data roaming is disabled such that when data roaming is enabled, the proper APN to use will have been previously identified. | 11-27-2008 |

20090253432 | System and Method for Generating a Blacklist for Femtocells - Provided are systems and methods for generating a blacklist for femtocells. According to an embodiment of the application, a mobile device generates and maintains a femtocell blacklist including an identification of at least one femtocell to be avoided by the mobile device. Upon detecting a femtocell, the mobile device determines whether the femtocell is identified in the femtocell blacklist. If the femtocell is identified in the femtocell blacklist, then the mobile device avoids any attempt to use the femtocell. This might allow the mobile device to conserve battery power and reduce wireless communication resources. Since the femtocell blacklist is generated and maintained by the mobile device, the network infrastructure does not need to generate and manage the femtocell blacklist. Also, there is no need for the mobile device to download a femtocell blacklist or updates thereof from the network infrastructure. | 10-08-2009 |

If the wireless device determines based on its SIM that none of the available wireless networks are high priority networks for registration, then the wireless device automatically selects an available wireless network for registration based on, for at least one of the available wireless networks that the wireless device previously registered to, whether CS (Circuit Switched) service was rejected but PS (Packet Switched) service was allowed. Next, the wireless device automatically attempts to register with the selected wireless network. In this manner, the wireless device attempts to register with a wireless network that does not reject CS service while allowing PS service. If the wireless device nonetheless registers with such a wireless network, then registration can be reattempted with another available wireless network. | 08-26-2010 |
