Patent number: 8229461Abstract: A method and a system for providing location information are provided. A location server receives a request for location information for the mobile station. The request includes an identifier for the mobile station. The location server determines whether the mobile station is at an enclosing location object by searching a location server database in response to the request. When the location server determines that the mobile station is at the enclosing location object, the location server obtains the enclosing location object from the location server database independent of a location request being sent to the mobile station, and provides the enclosing location object as the location of the mobile station. A sensor can be used to determine whether the mobile station is at the enclosing location object, and the location server database can be updated based on the sensor information.Type: GrantFiled: November 18, 2009Date of Patent: July 24, 2012Assignee: Nextel Communications, Inc.Inventor: Arun Manroa

Patent number: 8175063Abstract: Systems and methods for Walsh code assignment are provided. In accordance with the disclosed exemplary embodiments, when a set of mobile communication units (MU) is in a control/hold state, instead of a base transceiver station (BTS) assigning Walsh codes for respective dedicated control channels (dcch ) to the set of mobile communication units (MU) on a one-to-one basis, the base transceiver station (BTS) circulates the Walsh codes among the set of mobile communication units (MU). Thus, at a given time, the base transceiver station (BTS) has assigned the available Walsh codes to only a subset of the mobile communication units (MU) in the control/hold state. Accordingly, this Walsh code assignment allows the system to support more mobile communication units (MU) in the control/hold state.Type: GrantFiled: August 9, 2005Date of Patent: May 8, 2012Assignee: Nextel Communications Inc.Inventors: Nagi A.
