| 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 |

| 20110021204 | Methods And Apparatus For Prioritizing Voice Call Requests During Data Communication Sessions With A Mobile Device - A voice call request for a voice call involving the mobile device is received in a wireless network while the mobile device is engaged in a connected data communication service via the wireless network. The service utilizes a radio traffic channel between the mobile device and the wireless network and a data session for communication of data. In response to the receiving of the voice call request, the wireless network causes the radio traffic channel for the service to be torn down without terminating the data session. The wireless network also causes a voice call involving the mobile device to be established and maintained over a new radio traffic channel via the wireless network while the data session for the service is maintained. Subsequently, the wireless network identifies an indication that the voice call involving the mobile device has ended and, in response, resumes the communication of the data in the data session over a radio traffic channel. | 01-27-2011 |
| 20110122847 | System and Method for Registration and Packet Data Reconnect - Methods, mobile stations and networks are provided that cause a packet data service reconnect to be performed automatically after the occurrence of an event triggering registration, even in some circumstances where such a data service reconnect would not normally occur. This avoids complications that can arise due to the packet data service being discontinued upon registration and the resulting inability to reach the mobile station. | 05-26-2011 |

| 20090073883 | Methods And Apparatus For Controlling Wireless Network Operations Associated With Flow Control Process - Methods and apparatus for controlling wireless network operations associated with a flow control process which terminates data communications to a mobile station based on an out-of-coverage condition between the mobile station and a wireless communication network. In the wireless communication network, an indication is identified which indicates whether a mobile station utilizes an always-on connection for a data service. Based on the indication indicating that the mobile station utilizes the always-on connection, the flow control process is bypassed. Otherwise, the flow control process is performed. The always-on connection may be utilized for an e-mail application for the mobile station and involve a Point-to-Point Protocol (PPP) session. | 03-19-2009 |
| 20100190523 | METHOD AND APPARATUS FOR TRANSITIONING BETWEEN EVDO AND CDMA 1X SYSTEMS USING REDUNDANT DATA CALL BLOCKINGS - A method and apparatus of optimizing transitioning between EVDO and CDMA 1× systems in a hybrid access terminal, the method having the steps of: preventing a reconnect data call from being sent from the hybrid access terminal. The preventing step including checking whether a transition between an EVDO and a CDMA 1× system is successful; and if not blocking the data call, and/or checking whether an EVDO received signal strength indication is greater than or equal to a receiver sensitivity on the hybrid access terminal; and if yes, allowing the hybrid access terminal to connect to the EVDO system, and/or delaying a connection timer for connecting to the EVDO system and/or applying fast dormancy to the hybrid access terminal in an EVDO state. | 07-29-2010 |
| 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 |
