• identify, in response to the application of the at least one criterion, that the binding information instance is a candidate instance for removal;
• generate a request;
• transmit, to a policy control network device, the request;
• receive, from the policy control network device, a response to the request;
• and
• determine, in response to the receipt of the response, whether to delete or maintain the binding information instance.

A non-transitory computer-readable storage medium storing instructions executable by a processor of a binding service function device, which when executed cause the binding service function device to:

• apply at least one criterion to a binding information instance;
• identify, in response to the application of the at least one criterion, that the binding information instance is a candidate instance for removal;
• generate a request;
• transmit, to a policy control network device, the request;
• receive, from the policy control network device, a response to the request;
