Method for service subscription auditing

An apparatus comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus to perform:
• implementing a near-real-time radio access network intelligent controller;
• detecting an event triggering a need for an auditing of service subscriptions at an associated access node;
• transmitting a service subscription audit request to said access node, wherein said service subscription audit request comprises a list of service subscription identifiers regarding service subscriptions assumed to be active by said near-real-time radio access network intelligent controller;
• receiving a service subscription audit response comprising information about any existing service subscription for said near-real-time radio access network intelligent controller from said access node, wherein said service subscription audit response comprises one or more lists of service subscription identifiers regarding service subscriptions having records held by the access node;
• and
• carrying out a procedure to ensure that a configuration of at least one service subscription at the near-real-time radio access network intelligent controller corresponds to the information received from the access node.
