20090291695 | METHOD AND SYSTEM FOR PAGING MOBILE DEVICES IN A WIRELESS NETWORK - A paging initiation message is received at a first node transferred from the communication network. A paging announce message is generated at the first node based upon a last known location for the mobile station. The paging announce message comprises one or more identifiers associated with a proximate location of the mobile station. The paging announce message is sent to one or more paging groups. Each of the paging groups comprise one or more network elements associated with the one or more identifiers. A mobile paging message is generated at the one or more network elements when the one or more network elements comprise one or more network subelements identified by the one or more identifiers. The mobile paging message is sent to the mobile station transferred from the one or more network subelements. | 11-26-2009 |

20110021198 | Systems And Methods For Selectively Pre-Registering Data Paths For Mobile Stations - The present invention relates to systems and methods for selectively pre-registering a data path for a mobile station. In an embodiment, a serving base station receives a mobile-originated handoff-request message from a mobile station, wherein the mobile-originated handoff-request message identifies one or more target base stations. The serving base station then responsively determines whether to instruct each respective target base station to pre-register a data path for the mobile station. The serving base station then sends a respective serving-to-target handoff-request message to each identified target base station, indicating whether the serving base station is instructing that target base station to pre-register a data path for the mobile station. | 01-27-2011 |
20110022504 | Systems And Method For Establishing A Data-Path Between A Mobile Station And A Home Access Service Network Gateway - The present invention relates to systems and methods for establishing a data-path between a mobile station and a home access service network gateway (“ASN-GW”). During the authentication process, a visited ASN-GW receives a first message that identifies a home ASN-GW associated with the mobile station. After the mobile station has been authenticated, the visited ASN-GW receives a first data-path request message from a base station serving the mobile station, requesting a path for data-packet communication for the mobile station that extends between base station and the visited ASN-GW. The visited ASN-GW responsively uses the received identification to send a second data-path request message to the home ASN-GW which requests a path for data-packet communication that extends between the base station and the home ASN-GW. Once the data-path has been established, the home ASN-GW may monitor and/or place restrictions on the data being transmitted to and from the mobile stations. | 01-27-2011 |
20110026454 | WIRELESS COMMUNICATION SYSTEM - A method of operating a communication system comprises exchanging initial communications between a wireless communication device and a communication network over a wireless connection between the wireless communication device and a network access system and over a network connection between the wireless device and the communication network. The method further comprises, in response to a loss of the network connection due to a deterioration of the wireless connection, determining if a partial network entry process is possible to regain the connection, and if the partial network entry process is possible to regain the network connection, performing the partial network entry process. The method further comprises, in response to an improvement of the wireless connection and upon regaining the network connection, exchanging new communications between the wireless communication device and the communication network over the wireless connection and the network connection. | 02-03-2011 |
20110026455 | WIRELESS COMMUNICATION SYSTEM - A method of operating a communication system comprises exchanging initial communications between a wireless communication device and a communication network over a wireless connection between the wireless communication device and a network access system and a network connection between the wireless communication device and the communication network. The method further comprises performing a plurality of ranging processes to monitor a status of the wireless connection. Upon successfully completing a ranging process of the plurality of ranging processes, the method comprises determining a duration elapsed since the last successful ranging process and processing the duration to determine if the duration satisfies a criteria. The method further comprises, if the duration does not satisfy the criteria, then setting the indicator to indicate that a partial entry process is required to regain the network connection, and in response to the deterioration of the wireless link, processing the indicator to determine if the partial network entry process is required to regain the network connection. | 02-03-2011 |
20120014488 | METHOD AND SYSTEM FOR MANAGING WIRELESS LINKS IN A COMMUNICATION NETWORK - A method of operating a communication system comprises establishing a wireless device release time interval for a wireless device release timer at an access node upon establishing an initial network connection between a wireless device and the access node. An initial synchronization process is performed between the wireless device and the access node. The method continues with the access node sending an unsolicited synchronization message to the wireless device and starting the wireless device release timer. A second synchronization process is performed and upon successful completion of the second synchronization process, a success status synchronization response message is sent by the access node to the wireless device. The access node receives a synchronization confirmation message from the wireless device that comprises an identifier corresponding to the identity of the wireless device and upon receiving the confirmation message, the access node cancels the wireless device release timer. | 01-19-2012 |
20120014489 | METHOD AND SYSTEM FOR MAINTAINING WIRELESS LINKS IN A COMMUNICATION NETWORK - A method of operating a communication system comprises sending a frame by an access node to a wireless device where the frame comprises a packet. A counter is initialized and a timer for each frame is initiated. The method continues with the access node determining if a response associated with the packet is received before the expiration of the timer. If the response is received prior to the expiration of the timer, the counter and the timer are reset. If a response is not received prior to the expiration of the timer, the counter is incremented. Upon the counter meeting a criteria of a certain quantity of lost packets, the access node performs a synchronization process. | 01-19-2012 |
