1. A method for controlling a network slice quota, the method comprising:
sending, by an application function (AF), a request message including at least one action parameter to a network exposure function (NEF) on determining a network slice quota overflow or reaching a threshold or in case that a behavior of at least one user equipment (UE) falls outside an expected communication behavior;
forwarding, by the NEF, the request message including the least one action parameter to a network function (NF) upon successful authorization of the AF;
performing, by the NF, at least one expected action according to the request message based on the at least one action parameter, on reaching the network slice quota or reaching the threshold or in case that the behavior of the at least one UE falls outside the expected communication behavior,
wherein the at least one expected action comprises:
releasing, by the NF, low priority users by identifying a list of UEs based on policies, in case that an action type of the at least one action parameter indicates to release the low priority users;
releasing, by the NF, a list of users based on a list of UE IDs or a group ID of the at least one action parameter, in case that the action type indicates to release the list of users;
reducing, by the NF, a back off timer for a high priority user in case that a new registration request comes from the high priority user, in case that the action type indicates to reduce the back off timer for the high priority user; and
suspending, by the NF, a service for specific UEs based on the list of UE IDs or the group ID of the at least one action parameter, in case that the action type indicates to suspend the service for specific UEs.
