register the IoT devices at the second network function after a successful authentication.
9 . The network gateway of claim 8 , wherein the fourth network function is an Authentication Server Function (AUSF).
10 . The network gateway of claim 1 , wherein the network gateway acts as a Trusted WLAN Interworking Function (TWIF) for a first subset of IoT devices, a WLAN access node (AN) for a second subset of IoT devices, a Wireline Access Gateway Function (W-AGF) for a third subset of IoT devices, and a gateway with interworking capabilities for a fourth subset of IoT devices.
11 . A method performed by a network gateway, the method comprising:
receiving, from a first network function, User Equipment Route Selection Policy (URSP) rules for internet of things (IoT) device types associated with IoT devices,
wherein the URSP rules configure the network gateway to map data traffic from the IoT devices to an established protocol data unit (PDU) session with a second network function; and
mapping the data traffic between the IoT devices to a secure user plane session to the second network function based on the URSP rules for the IoT device types of the IoT devices.
12 . The method of claim 11 , further comprising:
sending, to a third network function, a registration request that indicates capabilities of IoT device types supported by the network gateway.
13 . The method of claim 11 , further comprising:
establishing the secure user plane session over the established PDU Session with the second network function.
14 . The method of claim 11 , further comprising:
authenticating the IoT devices via a fourth network function; and
registering the IoT devices at the second network function after a successful authentication.
15 . A network gateway for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the network gateway to:
receive a configuration that maps data traffic from local internet of things (IoT) devices to an established protocol data unit (PDU) session with an IoT Server; and
map the data traffic between the local IoT devices to a secure user plane session to the IoT Server based on the configuration.
16 . The network gateway of claim 15 , wherein the configuration includes User Equipment Route Selection Policy (URSP) rules for internet of things (IoT) device types associated with the local IoT devices.
