Abstract:
1. A method performed by a Mutual Aid QoS Function (MAQF) for determining policy for user equipment (UE) providing mutual aid for public safety purposes in a mutual aid enterprise operating area of a shared Long Term Evolution (LTE) system, wherein the LTE system comprises a core network that provides service to a plurality of radio access networks, the method comprising: receiving, by the MAQF, an indication that a UE is assigned to provide mutual aid in a mutual aid enterprise operating area, wherein the UE has a home enterprise operating area that is different than the mutual aid enterprise operating area, wherein the enterprise operating areas of both the home enterprise operating area and the mutual aid enterprise operating area are of the shared LTE system, and wherein each enterprise operating area of the home enterprise operating area and the mutual aid enterprise operating area is associated with a one or more different radio access networks of the plurality of radio access networks; detecting that the UE has entered the mutual aid enterprise operating area; selecting a set of mutual aid policy rules for the UE while the UE is providing mutual aid in the mutual aid enterprise operating area, wherein the set of mutual aid policy rules are different from, and provide a different level of service than, a set of policy rules applied to non-mutual aid users equipment (UEs) visiting the radio access networks associated with the mutual aid enterprise operating area.
