This call flow covers a simple case of call handover in GSM. Lets take an example where a user has an active call and is moving from the Rockville Cell to the Bethesda Cell. As the user moves, the call will be handed over by the Rockville Cell to the Bethesda Cell. Call release has been completed, now the RR connection is released by the MSC. The T8 timer is stopped as the handed over call's resources in the source BSC are released. The BSS informs the the MSC that the RR connection has been released.

Posted by jahangir1983 This scenario can happen either from the MO (calling) or MT (called) end. MS -> BS Release order is sent to the BS when the User presses the DISCONNECT button. RTCH: Order ACK_SEQ: 1 MSG_SEQ: 1 ACK_REQ: 1 ENCRYPTION: 0 ORDER: MOBILE RELEASE ORDER (normal) MS <- BS FTCH: Order ACK_SEQ: 1 MSG_SEQ: 2 ACK_REQ: 0 ENCRYPTION: 0, ORDER: Base Station Acknowledgement Order MS<- BS FTCH: Order ACK_SEQ: 1 MSG_SEQ: 3 ACK_REQ: 0 ENCRYPTION: 0 ORDER: Release Order (no reason given) At the end of the call the mobile enters the SDS sub state.
