Abstract
According to various embodiments, systems and methods disclosed herein can extract an actual address of a visitor location register (VLR) and an actual address of a mobile switching center (MSC) from signaling messages from a circuit-switched (CS) network in a foreign country and forward the actual addresses to a wireless network (e.g., a 5G network) whose subscriber is roaming in the foreign country through the CS network. The wireless network can use the actual address to determine the identity of the roaming country and the identity of the CS network so that the wireless network can exercise roaming control (e.g., authorizing or rejecting roaming calls) and billing users of the roaming subscribers based on which countries they are roaming in.
