A session control entity configured to control a data packet session of a mobile subscriber in a cellular network, at least one service being applied to the data packet session, the session control entity comprising a memory and at least one processing unit, the memory containing non-transitory instructions executable by the at least one processing unit for causing the session control entity to:
receive a first request from a service application entity located outside the cellular network of the mobile subscriber and in a service network requesting application of the at least one service, in which it is requested that the service application entity be informed of a current status of at least one session related parameter of the data packet session;
transmit a notification to the service application entity, the notification comprising the current status of the at least one session related parameter; and
