1. Airport Broadband Converged Communication Platform Functional Description

1.1 Professional Voice Trunking Communication Functions

The IDM converged communication platform creates a professional trunked intercom mode in a broadband network environment. Following the grouping mode of narrowband trunked systems, it provides users with large-area, multi-operational-unit, multi-level voice trunking dispatch functions, including group calls, private calls, talkgroup scanning, priority assignment, and other professional trunking communication features. 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 trunked communication systems, such as in areas not covered by private networks like underground spaces, and is not limited by private network coverage, enabling nationwide communication. In addition to voice trunking in broadband environments, it can also interoperate with existing local narrowband trunked networks, enabling mixed grouping of broadband and narrowband terminals and unified dispatch.

The main trunking communication functions include: group call communication, private call communication, talkgroup scanning, self-created temporary groups, quick return to primary talkgroup, priority setting (queuing and barge-in/forced release mechanisms), quick group switching, online member list, text message and image sending, talkgroup recording query and playback, and personalized contacts.

In addition to retaining the original narrowband trunked voice intercom mode, the IDM converged communication platform adds many practical functions based on network characteristics and command business needs. The main functions are as follows:

1.1.1 Group Call Communication

Group call is the most frequently used communication mode in trunked communications, enabling one-to-many calling. Users can initiate or receive voice calls within their group through the client program. According to professional trunked intercom characteristics, group calls operate in half-duplex mode.

The IDM platform can set different call buttons based on terminal type, including: soft PTT button (applicable to all smart terminals), dedicated PTT button (broadband video transmission terminals, law enforcement recorders, smart watches), and volume key PTT (broadband video transmission terminals, mobile phones).

1.1.2 Private Call Communication

The system provides point-to-point full-duplex calling mode, ensuring real-time bidirectional voice transmission. The system provides private call functionality, which through re-encoding, guarantees the personal privacy and business confidentiality of user conversations.

1.1.3 Talkgroup Scanning

The scanning function enables terminals to monitor multiple talkgroups simultaneously, preventing missed information from other groups due to failure to switch in time. The scanning function requires authorization and scan range configuration by the system management server.

1.1.4 Self-Created Temporary Talkgroups

This feature allows terminal users to create talkgroups for unexpected or temporary events and invite relevant personnel to join for group call communication, without requiring administrator assignment. Temporary groups are time-limited; the survival time of user-created temporary groups can be flexibly selected from 4 hours to 24 hours. After the survival time expires, the talkgroup is automatically deleted, avoiding long-term occupation of channels and server resources.

Temporary talkgroups are used the same way as regular groups. When creating a temporary group, members can be set to automatically join the temporary group without individual notification, enabling convenient, fast, and efficient temporary grouping.

1.1.5 Primary Talkgroup Priority Playback and Quick Return

When the platform administrator creates users, a primary talkgroup is set for each user. The primary talkgroup has priority playback during scanning. If a user switches to another talkgroup and enables scanning, voice communication on the primary talkgroup will be scanned and played with priority. A quick return button for the primary talkgroup is also provided—clicking it returns the user to the primary talkgroup without manual group switching.

1.1.6 Priority Setting (Queuing and Barge-in/Forced Release Mechanisms)

According to professional trunked communication requirements, all users are assigned corresponding priorities based on different levels. 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 channel through the barge-in/forced release function. Users with the same priority follow the queuing mechanism based on the order of PTT preemption.

The IDM converged communication platform subdivides 9 priority levels for all terminal users, which can be flexibly configured according to business needs.

1.1.7 Quick Group Switching

To facilitate terminal users in quickly and accurately switching talkgroups in actual operations, the terminal call main interface provides a sliding window for flexible and convenient talkgroup selection. Users can also quickly return to the primary talkgroup via the primary talkgroup shortcut key.

1.1.8 Online Member List

Broadband terminals can display the online member list of each talkgroup, allowing timely understanding of online broadband terminal personnel within the group, ensuring the effectiveness of real-time services such as video push or request reporting. Historical call records also allow playback of talkgroup calls at any time, ensuring no information is missed.

1.1.9 Text Message and Image Sending

In addition to voice communication, all members within a talkgroup can also exchange text messages and images, enriching communication methods among group members. Through timely aggregation of various information, commanders or field personnel can maximize their awareness of surrounding information.

1.1.10 Talkgroup Recording Query and Playback

Talkgroup calls are recorded in real time, and reported video is recorded in real time. All business data is automatically stored on the storage server. The system provides audio/video search functions for user retrieval and playback.

All call records of terminal group calls are recorded in the background. If users did not hear clearly, they can play back again, which also facilitates post-event queries. Recordings are time-limited based on storage space and will be cyclically overwritten when the storage limit is reached.

To ensure terminal security, the program automatically deletes temporarily stored audio/video files upon system exit.

1.1.11 Personalized Contacts

System administrators can configure personnel and device information as needed. Terminal users can also set personal information themselves. Members can add each other to contacts for quick personal calls.

1.1.12 Flexible Mobile Video Reporting and Push

The IDM converged communication platform supports flexible push of network-connected images to large screens at command centers at all levels, temporary command post monitors, command vehicle TVs/monitors, and portable command tablets. Images can be captured by fixed cameras or reported in real time by mobile terminals. Image reporting can be either active reporting by the terminal or proactive requests from higher levels to lower levels.

All converged communication platform terminals (mobile command terminals, broadband video transmission terminals) serve as mobile video sources. The system backend assigns advanced user permissions to these professional tools, enabling secondary handling of reported images, with the ability to push horizontally and vertically to one or more devices. If these terminals also have advanced permissions, they can continue pushing video to relevant personnel or devices. Moreover, these image-receiving terminals can utilize the trunking group call function, providing a practical means for multiple responsible personnel to jointly command field personnel reporting images.

1.1.13 Fixed Image Retrieval and Push

The IDM converged communication platform can connect to the user's local video surveillance network. Through the converged communication management platform, authorized users can import image resource lists, request access to images within their permission scope for viewing, and flexibly push them to various output devices, portable command terminals, handheld broadband video transmission intercom terminals, etc. This maximizes the application scope of video surveillance, popularizes image applications, and provides strong image resource support for field personnel.

1.1.14 Video Conference System Support

The IDM converged communication platform enables video conferencing with simplex voice. Devices such as mobile command terminals, broadband video transmission terminals, and video output terminals can serve as branch conference terminals, playing real-time conference audio/video or pushing it to video output devices for display on TVs or large screens. They can also serve as audio/video capture devices, transmitting on-site audio/video back to the video conference system backend, which can then route the terminal's audio/video resources to other venues for display.

In emergency or temporary situations, frontline commanders can use mobile command terminals to quickly set up a simple single-venue image video conference, using the image push function to send the speaker's image to relevant participants' Pads and broadband video transmission terminals. Participants focus on the speaker's image and use the intercom PTT to speak in reverse when needing to contribute.

1.1.15 GIS-Based Graphical Command Mode

Modern command modes are gradually evolving from single voice command to video command based on surveillance systems, and now to visualized command based on GIS systems. Through the integrated access platform of voice, video, positioning, data, and other resources, a comprehensive, three-dimensional command system is achieved, enabling the rear to understand on-site conditions through multiple means in a timely manner and issue effective instructions to the front.

The IDM converged communication platform can leverage the user's existing GIS map resources, using the platform's map service software module for map interface display. Commanders can directly push important alarm information on the map to mobile command terminals carried by leaders. Leaders can view the real-time distribution of various on-site resources on the map, view on-site video, the real-time handling process of alarms, and situation briefings. They can also communicate directly with the command center, frontline personnel, and other units/organizations/individuals through the communication subsystem.

Resources currently displayable on the map include vehicles (GPS, Beidou shipborne positioning), broadband video transmission terminals, mobile phones, law enforcement recorders, fixed cameras, and other mobile positioning information. Each device type is displayed with different icons and independent layers, which can also be displayed independently as needed.

Commanders can create temporary groups by circle-selecting on the map, automatically switching all terminals within the selected range to that group, enabling rapid unified command of all personnel within a designated area.

1.1.16 Audio/Video Storage and Retrieval System

Talkgroup calls are recorded in real time, and reported video is recorded in real time. All business data is automatically stored on the storage server. The system provides audio/video search functions for user retrieval.

1.1.17 Powerful System Management Platform

The IDM converged communication platform is equipped with a powerful system management platform. All server functions, user organizational structure, user account permissions, terminal device permissions, business data queries, platform logs, and platform operation statistics are managed through the management platform.
