Abstract
Gatekeeping for roaming WiFi callers includes: receiving, by a first wireless network node, from a second wireless network node, an authentication request identifying a user equipment (UE) that is requesting a call over WiFi and identifying a network address of the UE; based on at least the network address of the UE, determining a location of the UE; based on at least the location of the UE, determining whether the call is permitted; based on at least determining that the call is not permitted for the UE, responding with a message that blocks the call. Solutions also include: receiving, by the second wireless network node, from a packet data gateway, a request for a call over WiFi; based on at least receiving the request, transmitting the authentication request to the first wireless network node, the authentication request identifying the network address of the UE.
