Abstract

A method for location based policy for UE operating in different areas of a shared home LTE system includes: responsive to detecting a trigger, determining a first enterprise operating area (EOA) in which the UE is currently located, wherein the first EOA is one of a plurality of EOAs of the LTE system; determining whether the first EOA is a home EOA or a visited EOA; when the first EOA is the home EOA, selecting a first set of policy rules for the UE; when the first EOA is the visited EOA, selecting a second set of policy rules for the UE that provides a lower Quality of Service (QoS) than the first set of policy rules; if a trust relationship exists, selecting a third set of policy rules for the UE while in the visited EOA, which provides a higher QoS than the second set of policy rules.

Claims

1. A method for location based policy for user equipment (UE) operating in different areas of a shared home Long Term Evolution (LTE) system, the method comprising:

detecting a trigger, and responsive to the trigger, determining a first enterprise operating area in which the UE is currently located, wherein the first enterprise operating area is one of a plurality of enterprise operating areas of the LTE system;

determining whether the first enterprise operating area is a home enterprise operating area or a visited enterprise operating area for the UE;

when the first enterprise operating area is the home enterprise operating area, selecting a first set of policy rules for the UE;

when the first enterprise operating area is the visited enterprise operating area, selecting a second set of policy rules for the UE.

2. The method of claim 1, wherein the trigger comprises a location indication for the UE.

3. The method of claim 2, wherein the first enterprise operating area is determined based on a location of the UE determined from the location indication.

4. The method of claim 2, wherein the location indication indicates a change in location for the UE.

5. The method of claim 1, wherein the trigger comprises a request by the UE of at least one dedicated bearer.

6. The method of claim 1 further comprising providing the selected set of policy rules to an infrastructure policy enforcement function.

7. The method of claim 1, wherein the first set of policy rules includes a first set of Quality of Service (QoS) parameters, and the second set of policy rules includes a second set of QoS parameters, wherein the second set of QoS parameters comprises a change to at least one QoS parameter in the first set of QoS parameters.

8. The method of claim 7, wherein the first set of QoS parameters provides for at least one of a higher bearer allocation and retention priority or a higher scheduling priority than the second set of QoS parameters.

9. The method of claim 7, wherein a home enterprise is allocated the home enterprise operating area, and a visited enterprise is allocated the visited enterprise operating area, and wherein the second set of QoS parameters is determined based on an agreement between the home enterprise and the visited enterprise.

10. The method of claim 9, wherein the second set of QoS parameters provides for at least one of a higher bearer allocation and retention priority or a higher scheduling priority than a third set of policy rules for the UE in the visited enterprise operating area that are selected absent the agreement between the home enterprise and the visited enterprise.

11. The method of claim 1, wherein the second set of policy rules includes policy on the types of bearers that are allowed to be allocated for the UE in the visited enterprise operating area.

12. The method of claim 1, wherein the visited enterprise operating area is allocated to a visited enterprise, and the second set of policy rules is determined based on a trust relationship between a user of the UE and the visited enterprise.

13. The method of claim 1, wherein a user of the UE is associated with a home enterprise that is allocated the home enterprise operating area, wherein a visited enterprise is allocated the visited enterprise operating area, and wherein the second set of policy rules is determined based on a trust relationship between the user of the UE and a second user associated with the visited enterprise.

14. The method of claim 1, wherein a user of the UE is associated with a home enterprise that is allocated the home enterprise operating area, wherein a visited enterprise is allocated the visited enterprise operating area, and wherein the second set of policy rules is determined based on the user providing mutual aid in the visited enterprise operating area.

15. A system for determining location based policy for user equipment (UE) operating in different areas of a shared home Long Term Evolution (LTE) system, the system comprising:

a policy determination function comprising;

a processing device that is configured to,

detect a trigger, and responsive to the trigger, determine a first enterprise operating area in which the UE is currently located, wherein the first enterprise operating area is one of a plurality of enterprise operating areas of the LTE system;

determine whether the first enterprise operating area is a home enterprise operating area or a visited enterprise operating area for the UE;

when the first enterprise operating area is the home enterprise operating area for the UE, select a first set of policy rules for the UE;

when the first enterprise operating area is the visited enterprise operating area for the UE, select a second set of policy rules for the UE; and

an interface that is configured to provide the selected set of policy rules to an infrastructure policy enforcement function in the LTE system.

16. The system of claim 15, wherein the policy determination function comprises an LTE system Policy Charging and Rules Function (PCRF).

17. The system of claim 15, wherein at least a subset of the plurality of enterprise operating areas are allocated to a corresponding subset of public safety agencies.

18. The system of claim 15 further comprising:

a database comprising a plurality of entries, wherein each entry maps the second set of policy rules to a different home enterprise and visiting enterprise pair, and wherein the second set of rules for at least some of the entries is based on an agreement between a home enterprise that is allocated the home enterprise operating area, to which a user of the UE is associated, and a visiting enterprise that is allocated the visiting enterprise operating area.

19. A computer-readable storage element having computer readable code stored thereon for programming a computer to perform a method for determining location based policy for user equipment (UE) operating in different areas of a shared home Long Term Evolution (LTE) system, the method comprising:

detecting a trigger, and responsive to the trigger, determining a first enterprise operating area in which the UE is currently located, wherein the first enterprise operating area is one of a plurality of enterprise operating areas of the LTE system;

determining whether the first enterprise operating area is a home enterprise operating area or a visited enterprise operating area for the UE, wherein the home enterprise operating area is allocated to a home enterprise with which a user of the UE is associated, and the visited enterprise operating area is allocated to a visited enterprise;

when the first enterprise operating area is the home enterprise operating area, selecting a first set of policy rules for the UE;

when the first enterprise operating area is the visited enterprise operating area, selecting a second set of policy rules for the UE.

20. The computer-readable storage element of claim 19, wherein the method further comprises, if the home enterprise and the visited enterprise have a trust relationship or the user of the UE and the visited enterprise have a trust relationship or the user of the UE and a user associated with the visited enterprise have a trust relationship, selecting a third set of policy rules for the UE when the first enterprise operating area is the visited enterprise operating area, wherein the third set of policy rules provides at least one of a higher bearer allocation and retention priority or a higher scheduling priority than the second set of policy rules.
