Device and method for multi-mode broadcast short message receiving

Abstract

The invention provides a device and a method for multi-mode broadcast short message receiving. The device for multi-mode broadcast short message receiving comprises a mobile communication broadcast short message receiving device, a beidou broadcast short message receiving device, and a control device, wherein the mobile communication broadcast short message receiving device is connected with the control device and is used for receiving broadcast short messages through a public mobile communication system under the control of the control device in a configured mode, the beidou broadcast short message receiving device is connected with the control device and used for receiving broadcast short messages through a beidou positioning and navigation communication system under the control of the control device in a configured mode, and the control device is used for confirming whether the broadcast short messages received by the mobile communication broadcast short message receiving device is processed or the broadcast short messages received by the beidou broadcast short message receiving device is processed. The device and the method for multi-mode broadcast short message receiving only have a broadcast message receiving function, can achieve a broadcast short message receiving terminal with a low size and low cost, and can be widely used for vehicles, ships and personnel handheld terminals.

Description

technical field [0001] The invention relates to the field of wireless information broadcasting and receiving, in particular to a multi-mode broadcast short message receiving device and method through the existing public mobile communication system and the Beidou positioning navigation communication satellite system. Background technique [0002] The cell broadcast short message service is an important service provided by the mobile communication system, and is mainly used for distributing information to mobile users in a specific geographical area. Periodically broadcast data information to all mobile stations in the designated area. Cell broadcasting is a service that sends various real-time and dynamic classified information to mobile phone users by region and channel. It will make mobile phones like radios, and can receive channel content that mobile phone users are interested in anytime and anywhere. A wide range of cell broadcasting services are used, including stock i...

Problems solved by technology

[0005] But for such a broadcast system, a command machine can usually only manage 100 (up to 500) user machines

In addition, among all the current Beidou satellite ground terminal equipment, there is no equipment that only receives short messages.

Compared with the above-mentioned Beidou-1 user machines, these user machines are defined as focusing on positioning and navigation when they are designed, and also have short message communication functions. Therefore, the hardware composition of the user machine must not only have a receiving part, but also There is a launch part; in terms of software, these user machines not only have the functions of signal capture, tracking, and text calculation, but also coordinate conversion and other functions related to positioning and navigation, so the R&D and manufacturing costs of the equipment are correspondingly much higher. The volume and energy consumption of the equipment are also relatively large

In addition, the above-mentioned Beidou command machine can only manage a limited number of user machines, and it is impossible to broadcast short messages to tens of thousands (unlimited) Beidou terminal devices at the same time

[0006] However, the existing Beidou positioning and navigation terminals have many functions and are bulky, and the existing mobile communication cell broadcasting functions have not been actively used
