Priority handling of location services in a mobile communications network
First Claim
Patent Images
1. A method that provides a location service in a mobile communications network to provide a location estimate for a terminal device associated with a user, comprising the steps of:
- receiving a location request;
associating the user with a subscribed priority level;
prompting the user to enter a desired priority level;
receiving the desired priority level;
determining if the desired priority level exceeds the subscribed priority level;
in response to said determining step processing the location request to determine the location estimate of the terminal device, the precision of the location estimate based on the higher of the desired priority level or the subscribed priority level; and
reporting the location estimate.

Abstract
Provided is a method, computer program, and system that implements a location service in a mobile communications network to generate a location estimate for a terminal device associated with a user. The method takes a location request, and, with a precision that is dependent on an assigned priority level, estimates the location of a mobile phone. The computer program implements the method in software with modular programming. The system achieves the present invention by applying a location services algorithm to a mobile communications network.

generating in a Gateway Mobile Location Center (GMLC) a Mobile Application Part (MAP) message that requests the subscriber location from a Mobile Switching Center (MSC);
sending from the MSC to a Serving Mobile Location Center (SMLC) a MAP message that requests a location estimate;
returning from the SMLC to the MSC a location request as a Direct Transfer Application Part (DTAP) encapsulated MAP message; and
forwarding the location request to a Location Measuring Unit (LMU) through a Base Station Controller (BSC) as a DTAP message.

6. The method of claim 5 wherein the LMU estimates the location of the terminal device.
-
7. The method of claim 5 wherein the step of processing further comprises the step of returning from the LMU to the GMLC the location estimate.
-
8. The method of claim 5 wherein the SMLC allocates mobile communications network resources to estimate the location of the terminal device based on the priority level.
-
9. The method of claim 1 wherein the step of processing comprises the step of mapping the location service priority level to enhanced Multilevel Precedence Preemption (eMLPP) priority level.
-
10. The method of claim 1 wherein the priority level is determined by a Location Services (LCS) priority decision table.
-
11. The method of claim 1 wherein the priority level is dependent on at least a Preemption Capability Indicator (PCI).
-
12. The method of claim 1 wherein the priority level is dependent on at least a Preemption Vulnerability Indicator (PVI).
-
13. The method of claim 1 wherein the priority level is dependent on at least a Queing Allowed Indicator (QAI).
-
14. The method of claim 1 wherein the step of receiving a location request receives a location request from an emergency service.
-
15. The method of claim 14 further comprising the step of assigning the location request from the emergency service a highest priority level.
-
16. The method of claim 1 further comprising the step of reserving a highest priority level for emergency service.
-
17. Machine-readable instructions executable by a computer for providing a location estimate for a terminal device associated with a user in a mobile communications network, said instructions comprising steps for:
-
receiving a location request;
associating the user with a subscribed priority level;
prompting the user to enter a desired priority level;
receiving the desired priority level;
determining if the desired priority level exceeds the subscribed priority level;
in response to said determining step processing the location request to determine the location estimate of the terminal device, the precision of the location estimate based on the higher of the desired priority level or the subscribed priority level; and
reporting the location estimate. - View Dependent Claims (18, 19, 20)
