IDM Airport Broadband Fusion Dispatch System Fusion Communication Platform Function

1.1 Professional voice cluster communication function
The IDM integrated communication platform has created a professional cluster intercom mode in broadband network environments, following the narrowband cluster system grouping mode. It can provide users with large-scale, multi combat unit, and multi-level voice cluster scheduling functions, as well as professional cluster communication functions such as group calls, individual calls (private calls), call group scanning, and priority allocation. It is a multimedia mobile command system suitable for real-time command and monitoring of large-scale mobile groups. It can serve as a beneficial supplement to narrowband cluster communication systems, such as in areas where private networks cannot cover, such as underground spaces, and is not limited by the coverage area of private networks, allowing for nationwide communication. In addition to the voice cluster function in broadband environments, it can also interconnect with existing narrowband cluster networks locally, achieving functions such as mixed grouping and unified scheduling of narrowband and narrowband terminals.
The main functions of cluster communication include: group call communication, individual call communication (private call), call group scanning, self built temporary groups, quick return to the main call group, priority setting (queuing and strong insertion and disconnection mechanism), quick group switching, online member list, text and image sending, call group recording query and playback, personalized address book, etc.
The IDM integrated communication platform not only retains the original narrowband cluster voice intercom mode, but also adds many practical functions according to network characteristics and command business needs. The main functions are as follows:
1.1.1 Group call communication
Group call communication is the most frequently used communication mode in cluster communication, which can achieve a one to many call mode. Users can initiate or receive voice calls within their group through the client program. According to the characteristics of professional cluster intercom, group call communication is a half duplex call mode.
The IDM platform can set different call buttons based on the terminal type, including: soft PTT button (applicable to all smart terminals), dedicated PTT button (broadband image transmission terminal, law enforcement device, smartwatch), and volume button PTT (broadband image transmission terminal, mobile phone).
1.1.2 Call Communication (Private Call)

Temporary groups have timeliness, and the survival time of user created temporary groups can be flexibly selected from 4 hours to 24 hours. After the survival time ends, the call group will be automatically deleted without occupying channel and server resources for a long time.
Temporary call groups are used in the same way as regular groups. When creating a temporary group, members of the group can be set to automatically join the temporary group without the need for individual notification, making it convenient, fast, and efficient to meet the needs of temporary grouping.
1.1.5 Priority playback and quick return of the main call group
When the platform administrator creates users, a main call group is set for each user. When scanning the main call group, it will have a priority playback function. If the user switches to another call group and starts scanning, voice communication in the main call group will be scanned and played first. At the same time, there is a quick return button for the main call group, which can be clicked to return to the main call group without the need for manual group switching.
1.1.6 Priority Setting (Queuing and Strong Insertion/Removal Mechanism)
According to the functional requirements of professional cluster communication, all users are assigned corresponding priorities based on different levels, and high priority users have the right to occupy channel resources first. If the current group call channel is occupied, high priority users do not need to queue and can obtain the call channel through the wall insertion and disconnection function. Users with the same priority will execute a queuing mechanism based on the time of preemption of PTT.
The IDM integrated communication platform has subdivided 9 priority levels for all end users, and users can flexibly configure them according to their own business needs.
1.1.7 Quick group cutting
In order to facilitate the quick and accurate switching of call groups for end users in practical situations, the main interface of the terminal call allows for flexible and convenient selection of call groups through sliding windows, and quick return to the main call group can be achieved through the shortcut keys of the main call group.
