A telecommunications network including a Roaming Solution network, the
network including a Roaming Server, a National Location Register, and an
800 number Remote Switching Unit. The network may be integrated with a
standard SS7 type telecommunications network and further coupled to an
account based billing and call control platform that allows registered
wireless credit limited subscribers to place and receive calls when
roaming outside of their Home Provider's network. The network may verify
that the wireless subscriber's account balance is sufficient to place or
receive the call, translates the account balance into talk minutes, and
monitors the call for talk duration. The Roaming Solution network is
further operable to disconnect the call in the first negative minute and
immediately decrements the wireless subscriber's account.
