Description

522710 V. Description of the invention α) [Field of the invention] The present invention relates to a wireless voice conference system and method with busy dialing, which can be applied to any type of individuals or internal users of the company, which conduct wireless voice conferences with each other. , Such as home, office, factory, bank, or other users who need voice conference call processing can be used. [Background of the Invention]

In recent years, due to the advancement of digital electronic circuit technology, the ability of electronic devices to process signals has been greatly improved. Among them, the functions related to voice signal processing have been greatly enhanced. In addition, the current progress and universality of transmitting voice signals have made voice conference systems The technology can be achieved one by one and the functions are more complete.

However, the voice conference equipment used in the current market must be connected to the telephone line jack on the wall through a telephone line, and the power cord in the voice conference device must be connected to the power line jack on the wall. Limited by space, and does not have the function of busy dialing. And when a large office wants to conduct a multi-person online voice conference, the user must dial the dialer's number to log in to the voice conference. However, when the dial-up party is busy, the user of the client will not be able to connect to the line smoothly, and must Hang up the phone first, and then redial the same number. If you are still busy, you must hang up and redial again, repeating again and again until the connection is successfully established, which is a waste of time. For further explanation of conventional technology, please refer to Figure 1. Figure 1 is a flowchart of the steps for establishing a connection for the conventional technology.

Page 4 522710 V. Description of the Invention (2) Reveals a step-by-step procedure for the user to establish a connection when the dialer of a voice conference is busy. First, the user of the client first presses the necessary button to be busy (step 3 0 0), then obtains an available line (step 3 1 0), and the user of the client dials the phone to the remote dialer (step 3 2 0 0), if the remote dialer is busy (step 3 3 0 0), the user of the client must hang up the phone (step 3 4 0 0), and then wait for a period of time (step 3 5 0 0) After that, the line is busy again (step 3 0 0 0) to obtain the available line (step 3 1 0 0), and then dial again (step 3 2 0 0), and iteratively repeats until the remote dialer is not busy, and establishes voice Up to the meeting (step 3600); it is quite time consuming for the user and needs to be improved. [Summary and Purpose of the Invention] The present invention provides a wireless voice conference system and method with on-line dialing. A voice conference device is connected to a dialer. In the voice conference device, at least one fixed device is mainly combined. With the wireless transmission function of at least one portable device, when the user participates in the voice conference, the voice signal transmission of the voice conference can be performed without being restricted by the location in the wireless transmission range. That is, the main object of the present invention is that when using the technology of the present invention, the user of the client can freely move the portable device in the voice conference device, and can conveniently conduct a voice conference anywhere, and The portable device also provides the function of busy dialing, which can automatically dial the connection when the remote dialer is busy, eliminating the time for the user to repeat the dial-up connection. In order to achieve the above object, among the wireless voice conference system and method with busy dialing described in the present invention, the wireless voice conference system includes

522710 V. Description of the invention (3) A dialing party is a far end calling party, which can be a group. The dial-up party is connected to the exchange / central office through a telephone line, and then connected to a voice conference device through a telephone line. The voice conference device of the present invention mainly includes at least one fixed device and at least one portable device, and the portable device includes a busy dialing module, and the two are radio frequency (RadioFrequency; RF) signal mode to wirelessly transmit and receive voice messages. The user must first confirm that the fixed device has been registered (R e g i s t e r) in the portable device before signal transmission can be performed. The method for wireless voice conference with busy dialing according to the present invention includes: first, a user of a client dials from a portable device to a remote dialer to initiate a wireless voice conference. In this case, the remote dial-up party picks up the phone to start the wireless voice conference. At this time, the user sends the wireless call from the portable device to the remote dial-up party through the connection of a fixed device. On the other hand, the remote dialer wirelessly transmits a signal to the portable device via the connection of the fixed device for the user to answer. In this way, the user and the remote dialer talk to each other to complete the wireless voice conference. When the remote dialer is busy, the busy dial function is activated. After waiting for a period of time, it detects and retrieves an available line and dials to the remote dialer until the connection is successfully established and a wireless voice conference is started. . Preferably, the client user of the voice conference device of the present invention can use other portable devices using the same specification system to log in to the fixed device of the present invention, so that the user of the client can also dial through the fixed device.
