Method and system for transmitting assistance location data for fleet and asset management
First Claim
1. A method for transmitting assistance location information to a plurality of telemetry devices over a two-way wireless network, the method comprising:
- generating the assistance location information from a location reference network within the wireless network; and
broadcasting the assistance location information to the plurality of telemetry devices over the wireless network, wherein the telemetry devices are configured to determine respective locations of the telemetry devices independently from the location reference network when out of coverage of the wireless network.

Abstract
An approach is provided for transmitting assistance location information to a plurality of telemetry devices over a two-way wireless network (e.g., paging system). A location server, within a Network Operations Center (NOC), generates the assistance location information, such as Assisted Global Positioning System (A-GPS) data, from a location reference network within the wireless network. A messaging server broadcasts the assistance location information to the plurality of telemetry devices over the wireless network. The telemetry devices are configured to determine respective locations of the telemetry devices independently from the location reference network when out of coverage of the wireless network.
