A method and corresponding apparatus and system for base station implemented access control based on public land mobile network (PLMN) identity. When a base station receives a request to serve a mobile terminal, the base station will determine the mobile terminal's PLMNid and will decide based on that PLMNid whether to permit or deny the request for service. If the base station thereby decides to permit the request for service, then the base station may process the request in a normal manner. Whereas, if the base station thereby decides to deny the request for service, then the base station may reject the request outright.

A Packet Data Network Gateway (P-GW) to maintain session continuity for a UE in an LTE network comprises a communication transceiver and a processing system. The communication transceiver is configured to receive a first session setup message for the UE. The processing system is configured to process the first session setup message to determine if the UE qualifies for alternate P-GW access, and if the User Equipment qualifies for the alternate P-GW access, generate a second session setup message indicating a primary P-GW ID, a primary P-GW TEID, an alternate P-GW ID, and an alternate P-GW TEID. The communication transceiver is configured to transfer the second session setup message for delivery to a Service Gateway (S-GW) in the LTE network, wherein the S-GW automatically uses the alternate P-GW ID and the alternate P-GW TEID if performance of the primary P-GW ID and the primary P-GW TEID falls below a threshold.

A method and system for remote troubleshooting of a wireless communication device, such as a cell phone. The cell phone is programmed with server logic, such as a Telnet server application and an FTP server application. A computer at a customer service center for instance is programmed with client logic, such as a Telnet client application and an FTP client application. When a customer service representative receives a call reporting trouble with the cell phone, the representative may conveniently operate the client logic on the computer to log into the cell phone server logic, via a packet-switched network such as the Internet and via a wireless access network (and thus an air interface) serving the cell phone. Through that connection, the customer service representative can thereby cause the cell phone to perform various performance evaluations and can download the evaluation results to conveniently facilitate troubleshooting of the cell phone trouble.

Systems and methods for delivering media to media playback devices are provided. When a media playback device requests suspension of a media stream, the media is stored in a storage area associated with the media playback device. A media playback device can then request resumption of the media stream. The media playback device requesting resumption of the media stream can be the same or different from the device requesting suspension of the media stream.

System and method for providing media to media playback device

A system and method for providing information to a mobile station in a wireless network are provided. According to the method, a mobile station receives a control channel message wrapped in a unified control channel from a base station, and the mobile station determines a transmission type for incoming data, based upon the unified control channel. For a mobile station that operates with multiple transmission types, the mobile station does not have to monitor each of the control channels that the mobile station can receive, because the unified control channel tells the mobile station which transmission type to listen to. Therefore, the battery life of the mobile station can be extended, because the mobile station does not have to monitor numerous control channels.
