On the reverse-link, packets being sent to the first routing node are routed over the protocol tunnel from the mobile node to the second access node and then to the first routing node. In conjunction with these operations, the mobile node concurrently maintains separate IP interfaces for the routing nodes. In addition, steps are taken to ensure that packets are routed to the appropriate IP interface during the handoff. | 02-19-2009 |

In some aspects, access control techniques may be used to enable a user (e.g., an owner) of an access point to control whether an access terminal obtains service through the access point. For example, a user may temporarily disable access control at an access point to enable access points that register with the access point while access control is disabled to thereafter be allowed to obtain service through the access point. As another example, a shared secret may be provided to an access terminal whereby, upon presenting the shared secret to an access point, the access terminal is allowed to obtain service through the access point. | 09-15-2011 |

A first solution provides Interworking Solution (IWS) adding CPN sent to target Base Station Controller (BSC) via Mobile Switching Center (MSC) in Interoperability Specification (IOS) HO messages. A second solution provides that IWS sends CPN with Air Interface HO message and stores the CPN until UE transition to the target Radio Access Network and acquires a traffic channel. A third solution provides that IWS receives CPN from MSC with a paging message and stores the CPN until UE transition to the target Radio Access Network and acquires a traffic channel. A fourth solution provides sending AWI message to the target Radio Access Network from the MSC. A fifth solution provides that IWS sends CPN via Feature Notification Message (FNM) data tunneled to UE before the paging message to let user decide whether to accept a call before leaving 3G/4G cellular communication. | 11-24-2011 |

20120099586 | SYSTEMS, METHODS, AND APPARATUS FOR MANAGING IP ADDRESSES AND NETWORK TRAFFIC IN WIRELESS NETWORKS - Systems, methods and apparatus described herein include features that enable efficient management of keep-alive messages utilized to maintain IP addresses and/or PDN connections associated with idle data traffic channels. An access terminal may consolidate keep-alive messages for idle data traffic channels, reducing the number of keep-alive messages transmitted. An access terminal may select which idle data traffic channels to maintain, and may transmit a consolidated keep-alive message for associated IP addresses and/or PDN connections. Timers may be associated with PDN connections and sub-timers may be associated with IP addresses associated with a PDN connection. Keep-alive messages can be consolidated based on the timers, sub-timers and/or combination of timers and sub-timers. In a complementary method, a PDN gateway or other network node cooperates with access terminals to reduce network traffic. In another complementary method, the PDN gateway or other network node synchronizes the timers and/or sub-timers provided with an access terminal. | 04-26-2012 |
20120236776 | TARGET CELL SELECTION FOR MULTIMEDIA BROADCAST MULTICAST SERVICE CONTINUITY - Transfer of Multimedia Broadcast/Multicast Services (MBMS) over a Single Frequency Network (MBSFN) service and idle mode unicast service for a mobile entity from a source base station to a target base station may be managed by a base station or mobile entity of a cellular wireless communications system (WCS). Operations related to the transfer may include obtaining an MBMS status of the mobile entity, and/or obtaining MBMS support information for the base station. A network entity may facilitate MBMS discovery by a mobile entity, by transmitting a data element to the mobile entity including service identifiers mapped to corresponding cell identifiers to indicate respective MBMS services to be broadcast in an WCS area on adjacent cells identified by respective ones of the cell identifiers. The MBMS services may be broadcast within the WCS area using the adjacent cells previously indicated in the data element. | 09-20-2012 |
20120263089 | DEMAND-BASED MULTIMEDIA BROADCAST MULTICAST SERVICE MANAGEMENT - A method or system for managing demand-based multicast services in a wireless communications system (WCS) capable of both unicast and multicast signaling may include providing content requested by a mobile entity in an area of the WCS via a unicast session, determining that a concurrent demand level for the content exceeds a defined threshold for the area of the WCS, and initiating a multicast session for the content in the area of the WCS, in response to determining the concurrent demand level has exceeded the threshold. The method or system may include more detailed operations or aspects for measuring the concurrent demand level, transitioning signaling between unicast and multicast modes, communicating between network components, or related functions. | 10-18-2012 |
