1. A user equipment device (UE), comprising:
a radio; and
a processor operably coupled to the radio, wherein the UE is configured to:
establish a first relay connection with a first remote device, wherein the first relay connection relays communications between the first remote device and a network;
establish a second relay connection with a second remote device, wherein the second relay connection relays communications between the second remote device and the network,
transmit a first message to the network to initiate a radio access network-based notification area (RNA) update procedure for the first remote device, for the second remote device, and for the UE;
receive an acknowledgment message from the network comprising updated connection information for the first remote device and updated connection information for the second remote device;
transmit the updated connection information for the first remote device to the first remote device; and
transmit the updated connection information for the second remote device to the second remote device.
