BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a 1: 1 convergence ratio wireless telephone system using a multi-bell service. In particular, a wireless telephone equipped with a binary CDMA modem (hereinafter, abbreviated to B-CDMA wireless terminal) and a binary CDMA wireless access point (hereinafter referred to as "B-CDMA wireless terminal"). In the indoor telephone network consisting of B-CDMA AP), multi-bell technology is applied to make it easier to identify who the receiver is by generating various ring tones using the control ratio. The present invention relates to a 1: 1 convergence ratio wireless telephone system using a multi-bell service that enables a 1: 1 convergence ratio when a line is shared by multiple users.

In the conventional case, a service using a wired / wireless phone as a proxy and a voice over internet protocol (VoIP) phone service using a wireless LAN gateway are provided for a service for assigning a plurality of phone numbers to a single phone line to share a phone line. It's a big way.

The connection of the proxy concept, the former, is called Private Automatic Branch eXchange (PABX), which uses an expensive switching system such as a PBX to build an internal telephone network for a large number of users such as a school or a company. It is a service method that enables a 1: 1 collection fee. This method provides various functions such as call cost reduction, extension and call forwarding, and call forwarding. However, the exchange equipment is expensive, and the system construction for the telephone network is complicated.

In the case of the VoIP phone service using the latter wireless LAN gateway, since the voice is transmitted through the Internet using the VoIP phone or the VoIP gateway, a service having a convergence ratio of 1: 1 when transmitting and receiving is possible. However, this method also requires the purchase of a separate equipment for the service, and due to the nature of the Internet, unlike the PSTN, which is a closed network, it uses a public network.

That is, the above-described conventional methods have to introduce expensive equipment and complex systems to provide the above-listed services, or have a disadvantage in that voice quality is degraded and QoS is difficult to be guaranteed when voice is transmitted to the Internet.

Accordingly, the present invention has been proposed to solve the above problems of the prior art, and an object of the present invention is to provide a voice of a PSTN using a multi-bell service in an indoor telephone network composed of a plurality of B-CDMA wireless terminals and B-CDMA APs. While maintaining the quality, even when there is no equipment such as PBX, it is possible to logically 1: 1 convergence ratio when receiving a call like VoIP service, so that a receiver can be easily given a number of numbers on a single line and provide various ringing tones. It is to be distinguished.

The present invention for achieving the above object is composed of an antenna, a binary CDMA transmission module, a general-purpose asynchronous transceiver, a central processing unit, an RS-232 interface, a network side connection interface [codec, DAA, RJ-11 connector] and a memory. A B-CDMA AP having a 1: 1 convergence ratio when receiving a call by supporting a multi-bell service;

A number of B-CDMA wireless terminals using Binary CDMA technology make up the indoor telephone network to generate various ring tones using the enforcement ratio.

In addition, the B-CDMA AP is characterized in that the call is connected only to the wireless telephone corresponding to the telephone number distinguished by the multi-bell when a call from the outside.

In addition, the B-CDMA AP is characterized in that the 10 B-CDMA wireless terminals (101 ~ 110) can be connected to use.

Hereinafter, with reference to the accompanying drawings of the present invention will be described in detail.

1 is a diagram showing the overall configuration of a 1: 1 convergence ratio wireless telephone system using a multi-bell service according to the present invention, comprising a B-CDMA wireless terminal (101 ~ 110) and a B-CDMA AP (111) The basic diagram of the telephone network.

As shown, the B-CDMA AP 111 is connected to the PSTN 112 network by two lines. By using the multi-bell service function by the interception ratio provided by Hanaro Telecom, up to five distinct telephone numbers can be received on one line. By using the multi-bell service, the B-CDMA AP 111 secures up to 10 extensions, and when a call is received from the outside, the B-CDMA AP 111 analyzes the intermittent ratio of the multi-bell detected at this time. It finds the extension number and transmits a signal indicating that the call has been received only to the terminal corresponding to the extension number.

Therefore, a total of 10 B-CDMA wireless terminals 101 to 110 have a unique extension number in one B-CDMA AP 111 in the aggregation ratio configuration using a multi-bell service.

FIG. 2 is a diagram illustrating an embodiment of using a wireless telephone in FIG. 1. When a signal is sent to the B-CDMA AP 202 for a call between the B-CDMA wireless terminal 201 and the outside, the B-CDMA AP ( 202 assigns a line to the terminal requesting the external call when there is an available line among the two lines, and makes a call with the PSTN 203 network.

3 is a block diagram of a binary CDMA wireless access point device employed in the present invention. As shown in FIG. 3, an antenna 301, a binary CDMA transmission module 302, and a universal asynchronous transceiver (UART) 303, 304 are illustrated. , CPU (305), RS-232 interface (307), network side interface (codecs (308,309), DAA (310,311), RJ-11 connectors (312,313)) and memory (307) .

The binary CDMA wireless access point device configured as described above will be described in detail through a communication process. In the Retaw protocol, which is a binary CDMA protocol protocol, in order to form a group, networking must share a scan code for synchronization and a group code for networking, and addressing between terminals in the group. Retaw_ID is used.

Therefore, before using the B-CDMA AP 111, information about the B-CDMA wireless terminals 101 to 110 should be input in advance.

If you look at the Retaw_ ID part of [Table 1] below, you can see the serial number from CP (Cordless Phone) 1 to CP 5, and the code of this part becomes the unique identification number of each B-CDMA wireless terminal. .

In case of transmission, when a user sends a signal to the B-CDMA AP 111 to make a call with the outside using a B-CDMA wireless terminal, the signal enters through the antenna 301 shown in FIG. After inputting to the CPU 305 via the Binary CDMA transmission module 302, the Retaw_ID is compared and the registered terminal is connected to the PSTN 112 network only.

In the case of reception, when a call is received from the outside of the wireless terminal, the CPU 305 analyzes the interruption ratios 403 and 415 of the ring as shown in Fig. 4, and maps the mapping tables MT1 and MT2. By using the Retaw_ID (404,416) to find out the B-CDMA wireless terminal having the Retaw_ID connected to the telephone.
