BTS use circuit switching random access technique o grant the access and forward the information about originate the call to MSC. In mean time MSC will check the required mobile power and billing scenarios by using SACCH (slow associated control channel). after checking all the required credentials MSC transfer the call o PSTN then they allocate a physical channel to the mobile unit.
