Problems solved by technology

[0005] However, the existing bluetooth cordless phone technology cannot communicate between two terminals through the gateway, and the two terminals cannot be controlled by the gateway, which causes problems such as timing, billing, detection of on-hook and the like; if it is a pure walkie-talkie, Can't make outside calls

Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] figure 1 It is a schematic structural diagram of a bluetooth extension to which the method of the present invention can be applied. As shown in the figure, the Bluetooth extension 105 is composed of a random access memory (RAM) 101 , a microprocessor 102 , a Bluetooth communication module 103 and an LCD display screen 104 . The bluetooth communication module 103 is used for completing the communication between the bluetooth extension or the cellular phone with the bluetooth function and the telephone gateway; the microprocessor 102 is used for completing the data processing tasks in the communication process; the LCD display screen 104 is used for displaying related information. The bluetooth extension of this structure is the same as existing devices, and belongs to the prior art.

Abstract

The present invention discloses a method to realize synchronous calls with a plurality of Bluetooth terminals, which includes processes of Bluetooth voice gateway configuration, connection of asynchronous connectionless link, sub-machine number allocation, internal call request, division of pulse code modulation time slot and SCO link creating and connection, etc. Based on three SCO voice links created at the same time, the present invention ensures multi-path call. With an exchange chip, the present invention exchanges with time slot data on a PCM bus, thus keep real-time voice and reliability. Based on standard cordless telephone protocol and Bluetooth specification, the present invention realizes any call between any two of a plurality of Bluetooth sub-machines through gateway control by configuring a gateway exchange chip and a Bluetooth chip and has no impact on other Bluetooth sub-machines to call PSTN or other internal phones through the gateway, thus ensuring a simple and easycontrol method. Without any modification of a Bluetooth mobile phone and a gateway, the present invention reduces system development complexity and expands functions of Bluetooth sub-machines.

Description

technical field [0001] The invention belongs to the technical field of short-distance wireless communication, and in particular relates to a method for realizing simultaneous communication of multiple bluetooth terminals. Background technique [0002] Bluetooth technology is an open standard, short-distance, and low-cost wireless communication technology that can form a personal network in a communication environment between fixed and mobile devices, enabling various information devices within a short distance to achieve seamless resource sharing. Bluetooth works in the 2.4GHz ISM free frequency band, and the transmission distance is 10cm to 10m. If the power is increased, the transmission distance can reach 100m. The technology has low power consumption, little harm to the human body, and supports multiple application models. [0003] Bluetooth technology has been widely used in various terminal devices in the communication field, such as Bluetooth cordless phones, Bluetoo...
