  Hi-coins as reward: 0 (problem unresolved)

As you know in case of inbound user (2G,3G)

user will authenticate the network through USN and when everything is OK traffic will goes through Roamer UGW.



Problem:

in this case [inbound Roamer] Huawei USN will give information about Signaling only and no Traffic information will be available through lawful interception

Hi!

USN manages the signalling, while the traffic is managed by UGW.
