METHOD OF WIRELESS COMMUNICATION BETWEEN CELLULAR TELEPHONE DEVICES VIA TEXT MESSAGES

摘要

The proposed communication method relates to devices furnished with Bluetooth technology (BTD) interchanging text messages through the network of the devices, with no interference of the bluetooth information interchange protocol. These networked devices are recognized by their address (a single telephone number) and the SMS messages can be taken for text messages delivered to cellular devices. The user of a Bluetooth Technology Device (BTD) belonging to a cellular telephony network has the possibility to give a desired name to its device which is detected and recognized by others Bluetooth Technology Devices on the basis of this name. Another user of a Bluetooth Technology Device may interchange information with the first user by the so-called pairing function according which the "matching" of two devices is effected via a pre-agreed password so that consensus information interchange is thus guaranteed. For interchanging information between closely situated BTD users, there is created a central system (CNMS) managing the BTD names, an ensemble of entry processes and participation of the BTD to this system and finally a mechanism forwarding the text messages from a BTD participating to CNMS towards another device equally participating to this managing system via a text message-emitting mechanism of the corresponding networks whereto the BTD pertain. The users of the BTD will be registered on a CNMS and will notify the name of their device (which should be unique in the CNMS)and their telephone number as well. From this moment, the interchange of text messages between Bluetooth technology devices via a SMS mechanism provided by cellular telephony networks is established.
