Abstract: A method and apparatus for determining user equipment cell identification examines the age of the cell identification known to the user equipment when determining whether to use that cell identification or to obtain the cell identification through alternate means. The age of the cell identification known to the user equipment is examined by the user equipment, the communication system, or both by comparing the age to a predefined value. The age indicator can be transmitted by the user equipment to a network. If the age exceeds a predefined value, then the cell identification is obtained through network procedures. If the age is less than a predefined value then the cell identification known to the user equipment is accepted as current. Position information for the user equipment can be based upon the cell identification known to the user equipment or as obtained through network procedures.

Abstract: A mobile station database of cellular identifications and associated position information is stored in mobile station memory. The mobile station uses the position information in the database to assist in determining a current position for the mobile based on an identifier, such as cell ID, base station BSIC, PSC, or carrier frequency. A satellite vehicle signal is searched in an uncertainty region that is a function of position information associated with the current identifier. The uncertainty region can be limited by assumed platform dynamics via predefined velocity and acceleration information. Time maintenance for the mobile station can also be achieved through known approximate position from the position database and measurement of a single satellite vehicle propagation delay. The mobile station can compare a position determination obtained through satellite vehicle signals with position database information to determine the validity of that position.

Abstract: A method and apparatus for enhanced user control of location information for mobile devices. The method and apparatus provide user control within the mobile station of privacy policies that supervise responses to requests for location information. In an exemplary embodiment the mobile station includes a Privacy Engine, a Position Determination Module, and a User Interface. The Privacy Engine is a software module that controls the responses of the mobile station to location requests. The Privacy Engine preferably includes a Privacy Policy that may be modified by the mobile station user by means of wireless downloads, the User Interface, or by locally connected devices such as a personal computer, personal digital assistant, or laptop. Advantageously, the Privacy Engine or the Privacy Policy may be downloaded to the mobile station by means of a wireless data network or other data connection such as Bluetooth, infrared connection, Universal Serial Bus, etc.
