Benefits of technology

"The present invention provides a method and apparatus for selecting the best position determining equipment (PDE) source for a mobile communications unit (MCU) in a mobile communications system. This allows for the selection of a PDE source that can provide the desired location information based on the requirements of the requesting party. The method involves receiving a request for location information from the requesting party, selecting one PDE source from a plurality of PDE sources, and obtaining location information from that PDE source. The quality of service (QoS) parameters may include geographical accuracy, cost, age of information, and response time. The invention allows for the selection of a PDE source that meets the specific needs of the requesting party."

Embodiment Construction

[0032] One embodiment of a mobile or wireless communications network or system 10 is presented in FIG. 1. The mobile communications system 10 includes at least one Mobile Communications Unit 14 (e.g., a cellular phone) which communicates with a cell site equipment system 18 by an appropriate communications link 30a i.e., an RF link. A portion of this cell site equipment system 18 together with associated coverage areas is illustrated in FIG. 2. The cell site equipment system 18 of FIG. 2 includes a plurality of cells 22a-h. Each cell 22a-h includes a plurality of cell sectors 26a-c. Each cell 22a-h and its various cell sectors 26a-c cover a certain geographical area. At least one transmitter and at least one receiver (or a “transceiver”), as well as at least one antenna (all not shown), are associated with each cell sector 26a-c for handling all communications involving any Mobile Communications Unit 14 that is physically located within or possibly in proximity to the particular cel...

Abstract

A method and apparatus for managing the selection of location information sources (e.g., position determining equipment sites and handset-based location finding capabilities) to provide location information for a mobile communications unit (e.g., a cellular phone) are disclosed. Embedded within a request for location information on a particular mobile communications unit are one or more specifications regarding the quality of the requested location information. Such specifications is used to determine if any location information sources are able to provide the location information with the desired location information quality. Upon locating a location information source capable of providing the requested location information, the source is invoked to provide the particular location information. Once the location information is provided by the location information source, it is provided to the requesting party.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS [0001] This application is a continuation of U.S. patent application Ser. No. 10 / 071,117, entitled “Enhanced PDE Selection,” filed on Feb. 7, 2002; which is a continuation in part of U.S. patent application Ser. No. 09 / 796,972, entitled “Location Information Management System and Method for Mobile Communications Unit,” filed on Mar. 1, 2001, which is now U.S. Pat. No. 6,757,545, the entire disclosures of which are incorporated by reference herein in their entirety.BACKGROUND OF THE INVENTION [0002] Field of the Invention [0003] The present invention generally relates to the use of position determination equipment (PDE) in relation to a mobile communications system (e.g., a wireless network) and, more particularly, to selecting a PDE according to specifications in a location information request for a mobile communications unit. [0004] Wireless communications networks generally allow for voice and / or data communication between wireless stations...
