The calls are maintained by handing over a call from one cell to another. 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.

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.
