  • Patent number: 9125107
    Abstract: Disclosed herein is a method for determining the location of a mobile station with greater accuracy than serving base station location and yet preferably without the consumption of network resources typical of satellite-based location determination. The method is applicable in a scenario where a mobile station is ping-ponging (or has just been ping-ponging) between two non-coterminous wireless coverage areas. According the method, in that scenario, the location of the mobile station will be approximated conveniently as the location of overlap between the two wireless coverage areas, since it is most likely that the mobile station resides in that overlap area.

  • Patent number: 8873395
    Abstract: Quality of Service (QoS) priority values and thresholds are defined for various service types assignable to user equipment (UE devices) including multiple bandclass devices. The QoS thresholds can be used for determining whether resources of a default or alternate bandclass should be used for a new call request or whether a timer should be initiated to wait for additional resources to become available. A default QoS priority values can be assigned to each service type and used for voice calls requested by UE devices. QoS priority values with lower priority can be used for data calls. The priority of priority values can decrease as the data rate for the data calls increases. Thresholds for blocking call requests can be increased or decreased to improve likelihood that resources for call requests with higher priority service types are granted at the expense granting resources for call requests with lower priority service types.
