The wireless terminal of group system, such as the professional group system Y are established and communicated with intercom a, intercom b, intercom c respectively
Connection.If intercom a and intercom b is first group, intercom c is second group, below with reinforced electric phone a to first group of hair
Rise exemplified by group is exhaled and be described, after above-mentioned wired programme-controlled exchange X and professional group system Y establishes communication connection, when enhanced
Telephone set a need to first group of initiation group exhale when, reinforced electric phone a can send the first industry to above-mentioned wired programme-controlled exchange X
Business is asked, and is included in first service request for indicating that the group of cluster multi call function exhales header field, wired programme-controlled exchange X
First service request is received, after the object for determining first service request is first group of intercom a and intercom b, this has
Thread controlled switching system X then calls SIP Extended Protocols that first service request is sent into professional group system Y, the professional cluster
After system Y receives first service request, first service request can be sent to by intercom a and intercommunication by air protocol
Machine b, it is connected so as to complete reinforced electric phone a with intercom a and intercom b group calling communication.Above-mentioned wired programme-controlled exchange X
Also establish and be connected with dispatching desk Z, when dispatching desk Z needs to be scheduled control to professional group system Y, dispatching desk Z can be to
Wired programme-controlled exchange X sends control instruction, and the control instruction may include：Call, dropped calls are established, call is monitored, inserts
Enter call or call transfer etc., this is described exemplified by sentencing dropped calls.Above-mentioned wired programme-controlled exchange X receives above-mentioned
Control instruction, the object for determining above-mentioned control instruction are professional group system Y, then wired programme-controlled exchange X calls SIP extensions
The control instruction is sent to professional group system Y by agreement, and professional group system Y receives the control instruction, determines the control
Instruct as dropped calls, then professional group system Y is according to the control instructions of the dropped calls, interrupt the professional group system Y with
Call between dispatching desk Z.Above-mentioned wired programme-controlled exchange X can also receive the second business that above-mentioned professional group system Y is sent please
Ask, such as second service request is cluster broadcast call request, when intercom a needs to initiate cluster broadcast ＆ call, this is right
Say that machine a receives the cluster broadcast ＆ call to above-mentioned professional group system Y signalling of bouquet broadcast call requests, professional group system Y
Request, determining the object of the cluster broadcast call request includes reinforced electric phone a, reinforced electric phone b and enhanced telephony
Machine c, then the professional group system Y cluster broadcast call request is sent to by above-mentioned wired program control friendship by SIP Extended Protocols
Change planes X, and wired programme-controlled exchange X receives the cluster broadcast call request, and the cluster broadcast call request is sent to
Reinforced electric phone a, reinforced electric phone b and reinforced electric phone c are stated, so as to establish reinforced electric phone a, reinforced electric
Phone b and reinforced electric phone c are connected with intercom a call so that reinforced electric phone a, reinforced electric phone b and increasing
Strong type telephone set c may participate in the intercom a trunked call of cluster broadcast ＆ call.
