  • Patent number: 9380497
    Abstract: Disclosed is an arrangement in which a radio access network detects a trigger such as the RAN being threshold loaded, and the RAN responsively causes each of one or more served UEs to transition from operating in a mode in which the UE would engage in call initiation signaling via the RAN to set up the call extending through the RAN, so the UE would then engage in the call served by the RAN to operating in a mode in which the UE would engage in call initiation signaling via the RAN to instead set up the call extending through another RAN and would transition to be served by the other RAN, so the UE would engage in the call served by the other RAN. As disclosed, one RAN may be an LTE RAN, and the other RAN may be a fallback RAN such as a CDMA or GSM RAN.

  • Patent number: 9373091
    Abstract: A method and system for providing a user of a wireless communication device (WCD) with vending service. The WCD may present the user with data indicating items available for purchase from a vendor. The WCD may then receive the user's directive to order an item from the vendor. In response, the WCD may obtain data stored at a transponder in proximity to the WCD that indicates a location of the WCD. In one example, the transponder may be at a fixed location, such as by being affixed to a fixed object at a venue (e.g., a stadium seat), in which case the stored data may indicate the fixed location. The WCD may then send an order for the item and the obtained data to the vendor. In turn, the vendor may use the data to determine a location of the WCD and then deliver the item to the determined location.

  • Patent number: 9369952
    Abstract: Disclosed herein is a method and corresponding system for management of neighbor scanning in a cellular wireless communication system. A radio access network (RAN) sends, and a mobile station receives, a neighbor list update message (NLUM) containing a plurality of different neighbor lists. The mobile station then selects one of the neighbor lists based on a determined first rank-ordering of its active set members. Once the mobile station selects one of the neighbor lists, the mobile station scans the neighbors listed in the selected neighbor list in accordance with the selected neighbor list. If the mobile station detects a change in rank-ordering from the determined first rank-ordering to another rank-ordering, the mobile station may select and transition to another one of the neighbor lists and may begin to scan the neighbors listed in the selected other neighbor list in accordance with the selected other neighbor list.

  • Patent number: 9370016
    Abstract: A UE gauges how many UEs are currently served in each of various coverage systems, by evaluating downlink control channel signaling in each coverage system to determine from the control signaling an extent to which the signaling provides for UE scheduling and to establish a corresponding relative measure of an extent to which the coverage system is serving UEs. In an example implementation, this evaluation may involve eliminating from consideration any control channel signaling that is not associated with UE scheduling, so as to determine by exclusion an extent to which the downlink control channel signaling is associated with UE scheduling. The UE then compares such relative measures of the various coverage systems as a basis to select a coverage system in which to operate, such as by favoring operation in the coverage that thereby seems to be serving the fewest number of UEs.
