    摘要： 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.

    摘要： 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.

    摘要翻译： 本文描述的系统，方法和装置包括能够有效管理用于维持与空闲数据业务信道相关联的IP地址和/或PDN连接的保持活动消息的特征。 接入终端可以整合用于空闲数据业务信道的保持活动消息，减少发送的保活消息的数量。 接入终端可以选择要维护的空闲数据业务信道，并且可以发送用于相关联的IP地址和/或PDN连接的统一的保持活动消息。 定时器可以与PDN连接相关联，并且子定时器可以与与PDN连接相关联的IP地址相关联。 可以基于定时器，子定时器和/或定时器和子定时器的组合来整合保持活动消息。 在互补方法中，PDN网关或其他网络节点与接入终端协作以减少网络流量。 在另一种补充方法中，PDN网关或其他网络节点与提供有接入终端的定时器和/或子定时器同步。

    摘要： A method is performed by a device. The method includes determining whether the device is allowed to attach to an operator network based at least partially on whether all access point names in a minimum access point name list are enabled in the device. The device allows itself to attach to the operator network if it is determined that the device is allowed to attach to the operator network. The device prevents itself from attaching to the operator network if it is determined that the device is not allowed to attach to the operator network. The device can wirelessly receive a command to disable an access point name in the device. If an access point name on a detach access point name list is disabled, then the device detaches from the operator network and prevents itself from reattaching until an integrated circuit card in the device is removed and replaced.

    摘要： A method for inter-modem coordination is described. A first data connection to a network in a first network coverage area using a first air interface provided by a first modem is established. The method also includes detecting a second network coverage area with a second air interface provided by a second modem. A data call state of the second modem is determined by the first modem. The first data connection to the network by the first modem is terminated when the data call state of the second modem is no data call. A data call state of the first modem is determined by the second modem. A second data connection to the network using the second air interface provided by the second modem is initiated when the data call state of the first modem is no data call.

    摘要： A method for maintaining IP context during an inter RAT handover of a UE between an eHRPD network and an LTE network may include delaying a transfer of an Internet Protocol context for at least one active packet data network until an IP address for an attach (PDN) Packet Data Network has been assigned and in the case where the Internet Protocol address for the Attach Packet Data Network is not assigned, initiating a detach operation from the LTE network without the user equipment losing the Internet Protocol context of the at least one active Packet Data Network.
