Simultaneous Disconnect (Any State)

A simultaneous disconnect condition occurs when both the application and the network attempt to disconnect the call. The following scenarios illustrate different disconnect conditions and the asynchronous mode. For synchronous mode, the GCEV_DROPCALL event terminates the gc_DropCall( ) function.

Scenario 1:

• Glare at firmware - the firmware detects disconnect condition first but does nothing until Release command is sent.
• The network disconnects first while gc_DropCall( ) function arrives at the firmware before a Release command is sent to the network.

Scenario 2:

• Glare happens on the line - the firmware receives gc_DropCall( ) function after a Release command is sent to the network.
• The network disconnects first because the gc_DropCall( ) function arrives at the firmware after a Release command is sent to the network.
