Method for realizing grouping data in subway LTE (Long Term Evolution) system

Abstract

According to the implementation method for grouping data in the subway LTE system, a plurality of wireless terminal devices are respectively connected with a supplier server through a base station, and the supplier server is connected to a wireless device server through a switch to form a complete physical link. Based on a TCP (Transmission Control Protocol) connection-oriented custom protocol method, the wireless device server is used as a server to monitor a TCP socket, and a wireless device terminal is used as a client to actively perform TCP socket connection with the wireless device server. According to the user-defined protocol method based on UDP connectionless, a wireless device server and a wireless terminal device carry out data communication through a UDP socket. A short message interaction system independent of a short message interface provided by an integrator is developed by utilizing a bandwidth provided by an LTE system, so that the dependence on the integrator can be eliminated, and the integrator only needs to provide a channel and utilize a packet data mode, so that the service flexibility is greatly improved, and the timeliness of short message interaction is improved.

Description

technical field [0001] The invention discloses a method for realizing packet data in a subway LTE system, and relates to the field of short data communication of subway LTE wireless communication, in particular to a short data communication and its realization method using the packet data mode of the subway LTE wireless communication network. Background technique [0002] With the rapid development of the LTE system, the technology is becoming more and more mature. The LTE technology based on the 1.8 GHz dedicated frequency band has begun to completely replace the traditional narrowband trunking communication based on the 800 MHz frequency band, and has become the mainstream vehicle-to-ground wireless dedicated communication system in new domestic lines. [0003] In the traditional narrowband trunking communication based on the 800MHz frequency band, the priority of packet data is much lower than that of other narrowband services, resulting in a particularly slow transmission...

AI Technical Summary

Problems solved by technology

Although there is trunking SMS service in LTE trunking communication, which can also be used as the carrier of data communication, but because the trunking SMS service of each LTE manufacturer is different, and its trunking SMS service has a lower priority than other internal trunking services, In a large amount of data communication, the throughput of trunking SMS cannot meet the transmission volume of a large amount of data communication, resulting in an urgent need for a data communication carrier that is separate from LTE manufacturers and high throughput, so the packet data method based on the LTE system came into being pregnancy
