    Abstract: Aspects of the present disclosure provide techniques for preventing loss of IP continuity when transitioning between networks. Certain aspects provide methods that generally include initiating a first timer upon attempting to transition from a first RAT network to a second RAT network during an IP session and initiating a second timer if a channel in the second RAT network is successfully acquired. According to aspects, a device may transfer context of the IP session to the second RAT network if a session is successfully negotiated in the second network prior to expiration of the second timer and the first and second networks share a common core network for IP services.

    Abstract translation: 本公开的方面提供了用于在网络之间转换时防止IP连续性损失的技术。 某些方面提供的方法通常包括在尝试在IP会话期间从第一RAT网络转换到第二RAT网络时启动第一定时器，并且如果成功获取了第二RAT网络中的信道，则启动第二定时器。 根据方面，如果在第二定时器期满之前在第二网络中成功协商会话，并且第一和第二网络共享用于IP服务的公共核心网络，则设备可以将IP会话的上下文传送到第二RAT网络。

    Abstract: Architecture for performing WLAN offload in a wireless device is disclosed. In an exemplary embodiment, an apparatus includes an application section configured to form IP packets from data to be transmitted, a modem section configured to apply a cellular protocol to the IP packets to form cellular protocol packets, an endpoint configured to encapsulate the cellular protocol packets to form outer IP tunnel packets, and a WLAN interface configured to transmit the outer IP tunnel packets over a WLAN communication channel. In another exemplary embodiment, an apparatus includes a WLAN interface configured to receive outer IP tunnel packets over a WLAN communication channel, an endpoint configured to extract cellular protocol packets from the outer IP tunnel packets, a modem processor configured to remove a cellular protocol from the cellular protocol packets to form IP packets, and an application processor configured to extract received data from the IP packets.

    Abstract: 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.

    Abstract: Methods, apparatuses, and systems for reducing an occurrence of a Voice over Internet Protocol (VoIP) call from being disconnected in an Evolution Data Only (EV-DO) system are disclosed. The VoIP call is placed on hold and at least one keep-alive packet is issued to prevent a radio link from disconnecting. The at least one keep-alive packet is issued at least while the VoIP call associated with the radio link is on hold and is configured to reset a dormancy timer for the call at one or more network entities.
