Problems solved by technology

[0003] However, the current Beidou Bluetooth voice communication terminals on the market support a Beidou SIM card. Since the Beidou satellite system controls the communication data volume and communication frequency of the Beidou short message communication function, this single-card The amount of information transmitted by Beidou equipment is greatly limited. Although a high compression rate is adopted, it can only transmit 1 to 3 seconds of voice data

Abstract

The invention discloses a multi-card supporting Beidou Bluetooth voice communication system which is characterized by comprising a Beidou Bluetooth voice communication terminal as well as intelligent terminal equipment (11) in a Bluetooth wireless connection with the terminal. The Beidou Bluetooth voice communication terminal comprises an external SIM group interface (8), wherein the quantity of supported Beidou SIM cards can be expanded by the interface; and the terminal also comprises an internal SIM group (9), wherein the group is a Beidou SIM card group which is disposed inside the Beidou Bluetooth voice communication terminal, and multiple Beidou SIM card bases can be placed. After contents compiled by upper computer software are sent to the Beidou Bluetooth voice communication terminal, the Beidou Bluetooth voice communication terminal will automatically sub-package the sent contents according to the maximum data sending size of the Beidou SIM cards, then sub-packages are sent out by the different Beidou SIM cards in succession, and a receiving side combines the sub-packages according to an agreed protocol. In this way, communication data size can be expanded.

Description

Technical field [0001] The invention relates to the field of navigation communication, in particular to a Beidou Bluetooth voice communication system supporting multiple cards. Background technique [0002] As my country's Beidou navigation satellite system continues to mature and improve, Beidou application terminal products are also constantly enriched and gradually applied to all walks of life. Compared with the earlier Beidou products, Beidou related products are currently developing towards miniaturization and portability. Therefore, miniaturized products such as Beidou portable handsets and Beidou Bluetooth voice communication terminals are becoming more and more popular. At present, Beidou Bluetooth devices on the market use the short message communication function of Beidou RDSS to carry out voice transmission, thereby realizing the function of satellite voice intercom, which can be used in emergency rescue, field travel protection, border inspection and other fields.
