Distribution of positioning satellite information
First Claim
1. A method of operating a wireless communication system comprising:
- receiving and processing a position assistance request from a wireless communication device to determine a time of the request and a location of the wireless communication device;
processing the time of the request and the location of the wireless communication device to determine if a wireless communication system database stores positioning satellite information for the time and the location after having received the positioning satellite information from a location assistance system in response to a previous position assistance request;
if the wireless communication system database stores the positioning satellite information for the time and the location, then transferring the positioning satellite information for delivery to the wireless communication device; and
if the wireless communication system database does not store the positioning satellite information for the time and the location, then transferring the position assistance request for delivery to the location assistance system, receiving a response including the positioning satellite information for the time and the location, and transferring the positioning satellite information for delivery to the wireless communication device.

Abstract
A wireless communication device transmits a position assistance request. A system database receives and processes the position assistance request to determine a time of the request and a location of the wireless communication device and processes the time and the location to determine if the system database stores positioning satellite information for the time and the location. The system database transfers the positioning satellite information to the wireless communication device if the positioning satellite information is for the time and the location. The system database transfers the position assistance request to a position determining entity if the system database does not store the positioning satellite information for the time and the location.

9. A method of operating a wireless communication system comprising:
-
receiving and processing a position assistance request from a wireless communication device; determining a spatial relationship between a location of the wireless communication device and a geographic region associated with positioning satellite information contained in a wireless communication system database after having been received by the wireless communication system database from a location assistance system in response to a previous position assistance request; determining a validity period based on a position assistance request time; if a time of receipt of the positioning satellite information in the wireless communication system database is within the validity period and the spatial relationship meets a criteria, then transferring the positioning satellite information for delivery to the wireless communication device; and if the time of receipt of the positioning satellite information is not within the validity period or the spatial relationship does not meet the criteria, then transferring the position assistance request for delivery to the location assistance system, and receiving a response including the positioning satellite information for the location and the position assistance request time, and transferring the positioning satellite information for delivery to the wireless communication device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A wireless communication system comprising:
-
a wireless communication device configured to transmit a position assistance request; and a wireless communication system database configured to receive and process the position assistance request to determine a time of the request and a location of the wireless communication device, process the time and the location to determine if the wireless communication system database stores positioning satellite information for the time and the location after having received the positioning satellite information from a PDE in response to a previous position assistance request, transfer the positioning satellite information for delivery to the wireless communication device if the positioning satellite information is for the time and the location, and transfer the position assistance request for delivery to the PDE if the wireless communication system database does not store the positioning satellite information for the time and the location. - View Dependent Claims (18, 19, 20)
