A network device receives an attach request indicating that a user device is attempting a connection associated with a non-access stratum (NAS) and a particular interface, and generates a create session request that includes an indication that the connection for the user device is associated with the NAS and the particular interface. The network device provides, to a serving gateway (SGW) of the network, the create session request that includes the indication, and receives, from the SGW, a create session response that includes rules for handling the connection for the user device that is associated with the NAS and the particular interface, wherein the rules have been generated by a policy and charging rules function (PCRF) of the network. The network device provides, to the user device, an attach accept, that includes the rules, to permit the user device is to connect with the network and to utilize the rules.
