  • Patent number: 9462565
    Abstract: Certain aspects of the present disclosure propose techniques for Evolution-Data Optimized (EVDO) session handling during inter radio access technology (IRAT) mobility with support for S101 signaling interface. A UE may determine a mobility scenario for transfer of the UE among a first cell and a second cell, while the UE has an EVDO session. The UE may further determine whether pre-registration of a UE EVDO session is allowed via an S101 signaling interface. The UE may perform a procedure related to the EVDO session based on the determined mobility scenario and whether the pre-registration is allowed or not.

  • Patent number: 9451505
    Abstract: Aspects disclosed herein relate to effectively handling failure and retry mechanisms during pre-registration for an eHRPD optimized handover. In one example, a UE may be equipped to detect one or more instances of failure during a pre-registration procedure as part of an optimized handover process. The UE may further be equipped to perform one or more pre-registration retry processes based on the detected one or more instances of failure. In one aspect, the one or more instances of failure may include any combination of a permanent LTE connection failure, a temporary LTE connection failure, a session negotiation failure, a virtual connection failure when bringing up a data call, a link control protocol (LCP) failure, etc.

  • 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.

  • Publication number: 20150055569
    Abstract: Communication devices configured to identify a channel for network communication are disclosed. For example, an apparatus operable in a wireless communication network can receive a message that specifies a list of channels in operation in a network, remove at least one channel from the list of channels, and identify a channel from among the list of channels other than the at least one removed channel for communication with the network. The apparatus may be able to increase the likelihood that it will acquire the network, even though the network may be utilizing one or more channels that are not supported by the apparatus. Other aspects, embodiments, and features are also disclosed and claimed.

  • Patent number: 8880004
    Abstract: A device and method for resolving conflicts between air interfaces in a wireless communication system are disclosed. In one embodiment, the method comprises communicating over a first air interface, receiving a request for resources for concurrent use in communicating over a second air interface, determining that a conflict does not exist between resources for the first air interface and at least a portion of the requested resources for the second air interface, and concurrently communicating over the first air interface using resources for the first air interface and communicating over the second air interface using at least a portion of the requested resources for the second air interface.
