【資料目錄和簡介】：
This material provides a detailed illustration of the message flow observed for an AMR speech call
The message flow is focused upon communication with the circuit switched core and does not include communication with the packet switched core.
The UE starts by searching for candidate cells by correlating the RSSI with the code defining the primary SCH
The UE then achieves radio frame synchronisation and reads the BCCH logical channel
The BCCH provides system information including the cell selection criteria
If the cell passes the cell selection criteria then the UE establishes an RRC connection and registers with the core network
Having registered with the core network the UE returns to the RRC idle mode state and is ready to originate an AMR speech call
An originating AMR speech call is made and handovers are completed as and when required
Finally the AMR speech call is released and the UE returns to the RRC idle mode state
