Abstract

PURPOSE: An apparatus for switching an audio signal of a handset telephone is provided to simply realize a conference call by using the existing mobile communication network. CONSTITUTION: A subscriber transmits a service connection request signal to an HLR(Home Location Register) by using a terminal(701). The HLR receives the service connection request signal for extracting an identification number of an IP(Intelligent Peripheral) and a group setting number to transmit the group setting number to the IP(702). The IP transmits a request signal for service setting information to a subscriber server(705). The subscriber server extracts the service setting information to transmit the extracted service setting information to the IP(707). The IP generates call back short message information based on the service setting information to transmit the generated call back short message information to an SMSC(Short Message Service Controller)(709). The SMSC generates a call back short message based on the call back short message information and transmits the call back short message to a terminal of the other subscriber(711,713). The other subscriber responses to the call back short message so that the terminal of the other subscriber is connected with the IP(715,717). The IP operates a T(Time)-switch to set the identical call between the terminal of the subscriber and the terminal of the other subscriber(719,721).

The present invention relates to a method and system for providing a walkie talkie service based on a mobile communication network.

Developed for military use in the mid-20th century, the radio was extended to the postwar civilian sector, and as it became smaller and more portable, it became an effective and rapid short-range telecommunication tool. Since then, with the development of the mobile communication field, mobile phones have been widely used, but due to the ease of use of radios and the economical cost of having no separate communication costs, and the convenience of allowing multiple people to communicate at once, construction sites, government offices, after-sales services, etc. It is actively used by people in the field. However, a conventional radio requires a dedicated terminal and has a disadvantage in that only a call is possible between terminals having a matching frequency. Complementing the shortcomings of the radio, there is also disclosed in the prior art (Korean Patent Publication No. 10-2001-0018867) for a wireless one-way radio terminal. The conventional one-way radio combined terminal may include a radio function in an existing terminal by separately setting the radio communication module and the mobile communication module in the wireless terminal. That is, the conventional one-way radio terminal combined with the conventional one-way radio, and transmits a switching selection signal, a key input unit for transmitting a transmission or reception selection signal, a mode selection switch for receiving a switching control signal and switching to a CDMA mobile communication mode or a radio mode, It generates and supplies the local signal for CDMA mobile communication, the frequency supply unit that generates and supplies the local signal for radio, demodulates the radio RF received signal into the radio IF received signal, and transmits the radio signal. It transmits a radio transceiver transceiver and a switching control signal modulated to an RF transmission signal for transmission to the antenna and a mode selection switch, receives an IF signal, converts it into a voice signal, and transmits the voice signal to an IF signal. It is characterized by consisting of the transmitting MSM. In addition, the conventional one-way radio combined terminal can add the functionality of the radio to the wireless terminal using a CDMA / FM combined modem. In addition, the conventional one-way radio terminal combined with the conventional one-way radio terminal is used in an unstable time or region of the CDMA communication, thereby improving the performance of the system and providing a good call quality to the user.

However, the conventional one-way radio terminal does not include a conference call function. Conference calls have the advantage that several people can talk at the same time, using a regular landline or mobile phone does not require a separate terminal. However, the conference call has a disadvantage in that a subscription service is complicated for a company-only service, a system to be constructed by an operator is complicated, and usage fees increase, and main customers are limited to corporate customers.

The present invention provides a method and system for providing a mobile communication network based walkie talkie service that allows a user to easily conference calls using an existing mobile communication network without a separate facility by using a mobile communication terminal without purchasing a separate radio. The purpose is.

It is another object of the present invention to provide a method and system for providing a mobile communication network based walkie talkie service in which a plurality of subscriber stations on a mobile communication network can simultaneously receive voice traffic using a switching module.
