Geo-fence a UE to a location for fixed wireless access (LTE)

For a fixed wireless solution, its required to lock a subscriber to a specific area. That is if the UE tries to establish a data session in a different area, the session should be disallowed. Please advise how this can be achieved in an LTE network

There is no technical specification on FWA geo-fencing, so it is up to the network to implement the provisioning of the user with a location based data restriction.

Verizon has the patent US 11,510,024 B2 on exactly that topic, so you can find their entire method on how FWA geo-fencing can be achieved. The patent has been made public in 2022 and VZW owns its rights until 2040.
