5.1.10 Call Control Procedures
5.1.10.1 Incoming Call
An incoming call is always initiated by the host.
The host issues a ConnectReq command, identifying the PT by its IPUI.
The HW 86012/22 (FT) sends a paging message which commands the requested PT to
establish a DECT connection. If the PT receives this paging message, it connects to the FT.
When the connection has been established the HW 86012/22 issues a ConnectInd
command, and thereby returns a call handle to the host.
Upon reception of the ConnectInd command, the host shall check the IPUI. In case it is
different from the requested IPUI, the host may assume that an outgoing call is overlapping
the incoming call.
The host may immediately send data using the data channel with that call handle. It shall
process all data from that data channel.
Note:
This works only after having started LAP.
5.1.10.2 Outgoing Call
An outgoing call is always initiated by the PT.
The PT establishes a DECT connection with the FT.
When the connection has been established the HW 86012/22 issues a ConnectInd
command, and thereby returns a call handle to the host.
The host may immediately send data using the data channel with that call handle. It shall
process all data from that data channel.
Note:
This works only after having started LAP.
5.1.10.3 Call Release, Host initiated
A call is released by the host, when it issues DisconnectReq command.
The HW 86012/22 (FT) immediately releases the call.
After call release, the HW 86012/22 informs the host, by sending a DisconnectInd command.
Upon reception of this command the host shall check the value of the received call handle. If
different from the call handle in the DisconnectReq command, the host may assume an
overlapping PT initiated call release.
By reception of the DisconnectInd command, the call handle is no longer valid and must not
be used by the host.
5.1.10.4 Call Release, PT initiated
When a PT requests a call release, the HW 86012/22 (FT) immediately releases the call.
After call release, the HW 86012/22 informs the host, by sending a DisconnectInd command.
By reception of the DisconnectInd command, the call handle is no longer valid and must not
be used by the host.
