Abstract
In one aspect, a method includes generating, using a User Plane Function (UPF) of a core element of a network, a query to retrieve information associated with one or more Data Network Names (DNNs) configured in at least one other UPF in the network; transmitting the query to a Network Repository Function (NRF); receiving a response from the NRF, the response including IP address subnets of the at least one other UPF associated with the one or more DNNs; dynamically generating an Access Control List (ACL) to block mobile-to-mobile communication between User Equipment (UEs) in the network, using the IP address subnets received as part of the response, wherein each of the UEs is assigned an IP address from among the IP address subnets; and blocking M2M communication using the ACL dynamically generated.
