  • Publication number: 20160135089
    Abstract: A method of wireless communication by a UE includes receiving an indication information; determining, based on the indication information, whether a connection of the UE is authorized to be offloaded from a first channel to a second channel; determining, when the connection is not authorized to be offloaded, whether there is an ongoing handover procedure to offload the connection of the UE from the first channel to the second channel or whether the indication information is received in a message corresponding to a request to deactivate a default evolved packet system (EPS) bearer of the connection of the UE. The method further includes disregarding the indication information when the connection is not authorized to be offloaded and it is determined that either there is an ongoing handover procedure to offload the connection of the UE from the first channel to the second channel or the message corresponds to a request to deactivate a default EPS bearer of the connection.

  • Patent number: 9185730
    Abstract: Aspects disclosed herein relate to enabling fallback to a second data service based on whether one or more fallback conditions are present before or during establishing a data context with a first data service. In one example, a UE may be configured to determine whether one or more fallback conditions are present before or during establishing a data session with a first data service. The UE may be further configured to prohibit further attempts to establish a data context to access the first data service based on the determination of the presence of at least one of the one or more fallback conditions. Some aspects disclosed herein relate to enabling fallback to a HRPD data service based on whether one or more fallback conditions are present before or during establishing a data context with an eHRPD data service.

  • Publication number: 20150245266
    Abstract: Various aspects directed towards expediting an inter-RAT (radio access technology) reselection are disclosed. A user equipment (UE) operates according to a first RAT and utilizes an evolved multimedia broadcast multicast service (eMBMS) via the first RAT. A second RAT, which is unable to support eMBMS, is selected such that operation of the UE transitions from the first RAT to the second RAT. A reselection of the first RAT is then expedited by modifying at least one of a dormancy timer value initialization, a reselection timer value initialization, or a frequency priority.

  • Patent number: 8982836
    Abstract: 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.

  • Patent number: 8971244
    Abstract: 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.

  • Patent number: 8964568
    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.
