Enhanced TETRA digital cluster wireless scheduling system in combination with wired scheduling station

Abstract

The invention discloses an enhanced TETRA digital cluster wireless scheduling system in combination with a wired scheduling station. The enhanced TETRA digital cluster wireless scheduling system comprises a TETRA digital cluster system, the wired scheduling station, a vehicle interphone or a handheld interphone and a wireless scheduling station; the wireless scheduling station is provided with a display and a local database; terminal information and communication group information are stored in the local database; when being connected to a network manager, the local database can update the terminal information and the communication group information in the database; the display can display the terminal information and the communication group information read from the local database; and the wired scheduling station is connected to the TETRA digital cluster system through an Ethernet. According to the enhanced TETRA digital cluster wireless scheduling system disclosed by the invention, abundant TETRA digital cluster scheduling services, such as group calling, individual calling, short messages, tapping, de-tapping, remote starting, remote stopping and dynamic recombination, can be realized; therefore, a scheduler obtains service experience same as that of the wired scheduling station; and simultaneously, the enhanced TETRA digital cluster wireless scheduling system has the advantages of being rapid to deployed, and not limited by wired network resources and the like.

AI Technical Summary

Problems solved by technology

The wired dispatcher is connected to the TETRA digital trunking system through Ethernet. Although it has powerful functions, it is complex to deploy and depends on wired resources. It can only be used in fixed places such as command center buildings, and it is difficult to meet the needs of outdoor on-site command and dispatch scenarios. , rapid deployment and other requirements

The existing wireless dispatching systems on the market are all based on TETRA digital trunking vehicles for simple secondary development, and can only provide some TETRA digital trunking services such as single call, group call, short message, and dispatch. However, there are several such wireless dispatching systems. Key issues cannot be resolved:

[0003] 1. The dispatch service seriously consumes air interface (air interface) resources

The dispatching service combines TETRA digital trunking terminals in different formations into one formation to achieve the purpose of joint operations and task execution. The dispatching services of the existing TETRA digital trunking wireless dispatching stations on the market are all on the side of the wireless dispatching station It is realized by connecting the voice channel of each station with hardware equipment. Therefore, the formation of each station must occupy an air interface time slot. If there are several formations for dispatching, it needs to occupy several time slots of the air interface, and the air interface resources It is very valuable. Taking a single-carrier frequency base station as an example, the air interface only has 3 business time slots, that is, it can only support 3 group calls, so the practical significance of the dispatching function is not great in this case

[0004] 2. Advanced scheduling functions such as remote start, remote kill, and dynamic reorganization cannot be realized

However, the TETRA digital trunking standard determines that these advanced dispatching functions cannot be realized only through the air interface, and only the wired dispatching station can realize these functions, which makes the wireless dispatching station have great limitations in the field command and dispatching process

[0005] 3. The volume is large and the weight is heavy, which does not meet the requirements of portability

The existing TETRA digital trunking wireless dispatching consoles on the market need to stack many vehicles, and even use a nearly 2-meter rack for installation, and also need to configure server equipment. Both the server and the vehicles need power supply, so they are not portable. , rapid deployment requirements, and high requirements for the environment, basically can only be used indoors or in fixed places, contrary to the original intention of users to need wireless dispatching consoles
