Today s communication landscape is changing quickly. Voice communications alone cannot satisfy enterprise requirements for staff interaction and information sharing, and data services are increasingly critical for meeting strategic objectives. Emergency response and public safety: A single network with advanced technology providing both traditional Private Mobile Radio (PMR) and broadband services, including images, data, and video, speeds responses and saves lives. Metro: With the development of the metro industry, operators need faster, more efficient, and safer travel, and passengers expect a more comfortable trip. Train-to-ground broadband networks providing Closed Circuit Television (CCTV), Wi-Fi, Passenger Information System (PIS), and a Communication-Based Train Control System (CBTC) carrier have become imperative. Airport authorities and port areas: Guaranteeing the quality of ground or yard services and minimizing delays, through the delivery of simultaneous voice, data, and video, are urgently required to reduce operating costs. Other industries: In oil and gas, the smart grid, and mining, smart data terminals are often dispersed in remote areas where real-time wireless data acquisition and on-site video are more convenient and effective than wired technology to ensure staff and product safety.

Enhanced Voice Dispatching Services Group Call/Broadcast Call Group call is point-to-multipoint call between a UE and multiple independent dispatching consoles which enables a UE or a dispatching console to establish point-to-multipoint calls. Broadcast call is a point-to-multipoint (P2MP) call initiated by the dispatching console only and the floor can t be preempted. Broadcast group calls include network-wide broadcast groups and areaspecific broadcast groups. All UEs in a specified area can receive broadcast calls. Group Call/Broadcast Call Broadcast Medical Group Police Group Fireman Group Private Call Private calls (P2P calls) in full-duplex mode are enabled between trunking users, between trunking users and dispatching console users, or between dispatching users. Private calls are in point-to-point full-duplex mode, which ensures that only the two parties in a private call can hear each other. Hello Private Call Hello Emergency Call Emergency calls have the highest priority. With this feature, information is reported to predefined users promptly in emergency. User can press the emergency call button on top of a terminal to start an emergency call without dialing or pressing the PTT button. Emergency Call Emergency 6 Huawei elte Trunking Features

DMO DMO is a supplementary function and can be used for communication when an area has no LTE signal. In DMO mode, a user can talk to other users on the same frequency after pressing the PTT button on the UE. When the speaker is talking, other users cannot preempt the floor. After the floor is released, other users can press the PTT to talk. DMO Priority Call/Pre-emptive Call This basic feature enables UEs to preempt the floor based on their priorities after a group call is set up. When a UE applies for the floor but the speaker already exists, the dispatching system compares the priority of the UE applying for the floor with that of the speaker. If the speaker has a lower priority, the dispatching system releases the floor and allocates it to the UE applying for the floor. If the speaker has a higher priority, the dispatching system does not release the floor. During the floor release, the UL voice resources of the former speaker are also released. The former speaker then becomes a listener.

Security End-to-End Encryption End-to-End Encryption can encrypt PTT voice stream, private call voice stream and short message to prevent eavesdropping on the sensitive communication. The terminal that supports E2E encryption should be equipped with a TF encipher card, which be authenticated by the KDC. When initiating an enciphered call, a caller obtains a session key from the KDC through the eafe, and the KDC distributes the session key to the callee. The caller will encipher the voice stream by the TF module, and the callee will decipher the voice steam with the same session key. The network only transmits the stream that can t be decrypted.

Reliability Fallback Mode Fallback mode allows the enodeb disconnected from the CN to support basic functions of PTP calls and group calls within its coverage area to improve system reliability. Fall Back Mode PTP + Group call + Monitoring CN Geographical Redundancy This feature implements NE-level 1+1 cold redundancy of CNs by reuse the S1-flex load balancing algorithm in case of regional disasters. The active and standby NEs will periodically check the status of each other using handshaking. If handshaking is normal, each NE considers that the peer NE is normal. If the active NE becomes faulty, the standby NE detects the fault by heartbeat detection, and switches to the active state within 3 minutes. ecns enodeb Normal Situation ecns enodeb ecns enodeb Disaster Situation ecns enodeb NodeB Board Redundancy If an LBBP is faulty or its resources are insufficient, the cell served by the LBBP can t be dynamically reestablished on the LBBP. With inter-lbbp redundancy, the cell can be reestablished on another LBBP with available resources or on a backup LBBP. In this way, services in the cell can automatically recover and service interruption duration is reduced. RRU RRU RRU PWR FAN LBBP LBBP LMPT PWR Huawei elte Trunking Features 15
