Abstract

PURPOSE:To select a call opposite party automatically and to improve the communication efficiency by providing a selective call equipment having calling and called functions to a radio equipment of a mobile station and providing a calling selective call equipment on a terminal equipment of a base station. CONSTITUTION:In the case of communication from a mobile station 1 to a terminal equipment 6a of a base station, a selective call number specific to the terminal equipment 6a is set via a radio equipment having calling and called selective call functions provided on the station 1 and transmission is made to the base station 3. A radio equipment 5 for the base station provided with a line distribution function in the station 3 discriminates to which terminal equipment of the base station a signal is transmitted, connects a line to the terminal equipment 6a being the discrimination opposite party to attain communication between the station 1 and the terminal equipment 6a. In the case of communication to a mobile station 2 from a terminal equipment 6b of the base station, the selective call number added to the station 2 is set to the terminal equipment 6b and a signal is sent to the station 2 via the radio equipment 5. The station 2 detects the signal sent from the terminal equipment 6b to attain the communication. Thus, the communication opposite party is automatically selected and the efficient communication is attained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication system that performs 1:1 communication between a plurality of mobile stations and a plurality of devices on the base station side.

[Prior Art] Conventionally, when there are communication facilities at a plurality of locations on the base station side and a plurality of mobile stations, communication as shown in FIG. 4 has been carried out.

When making a call from the base station radio 4a of the base station 3 to the mobile station 1, when transmitting from the base station radio 4a, the mobile station 1
is specified and transmitted, and a call is made between the base station radio 4a and the mobile station 1.

Furthermore, when making a call from the mobile station 1 or 2 to the base station 3, the mobile station 1 or 2 selects one of the base station radios 4a to 4C of the base station 3 and makes the call.

This selection is all done by voice, and when the person you want to talk to tells you which person you want to communicate with, the person who hears it recognizes it on their own, and if you are called, you can communicate with the other party. The base station radio is capable of transmitting and receiving multiple frequencies, automatically searches for an empty channel, and connects the line with the mobile station.

[Problem to be solved by the invention] However, since conventional communication systems were configured as described above, it was necessary for the operator to recognize the other party in words, resulting in a loss of call time, and it was difficult to use efficient wireless communication. could not be used.

In order to solve this problem, the purpose of this paper is to provide a system that can automatically select a calling party.

[Means for Solving the Problems] In order to solve such problems, the present invention provides a single mobile station radio device with a selective discharge device having calling and receiving functions, and the base station radio device When the ejection signal is received, the called base station terminal is connected to it, and the base station terminal is provided with a selective ejection device for calling.

[Operation] Base station in this invention! ! ! , &1 are selectively called by signals transmitted from the mobile station and automatically connect with each terminal of the base station.

[Embodiment] FIG. 1 is a block diagram showing an embodiment of the present invention.
■, 2 is a mobile station equipped with a radio with a selective calling function for calling and called calls, 3 is a base station that issues commands to mobile stations 1 and 2, and 5 is a selection sent from the mobile station. A base station radio with a line distribution function, which has a function of automatically distributing lines by detecting a call signal, 6 is connected to the base station radio with a line distribution function 5, and is a selection for calling a mobile station. It is a base station terminal with a microphone and speaker that has a calling function.

In the device configured in this manner, for example, in order to make a call from the mobile station 1 to the base station terminal 6a, the mobile station 1 sets and transmits a unique selective call number to the base station terminal 6a. The transmitted signal is received by the base station 3, and a base station radio with line distribution function determines to which base station terminal the signal was transmitted, and the base station terminal 6 of the determined partner
A line can be connected to the mobile station 1 and the base station terminal 6a to make a phone call. At this time, other base station terminals 6b cannot talk to each other because they are not selected.

Further, when making a call to the mobile station 2 from the base station terminal 6b, for example, the selective calling number added to the mobile station 2 is set and transmitted at the base station terminal 6b.

The transmitted signal is transmitted to the mobile station 2 via the base station radio with line distribution function. Therefore, since the mobile station 2 detects the signal transmitted from the base station terminal 6b,
This allows you to make calls. At this time, since mobile station 1 is not calling its own station, it is not possible to make a call.

However, the base station radio and mobile station radio constantly monitor the line and are always ready to make calls.

However, the channel used for the call is detected to be internally disabled and is no longer used. This detection is performed until there are no empty channels left. Also, when all channels are in a talking state, busy information is sent to the user. When making a 0 call, the user presses (
When a call is made (transmission), a selective calling number is sent out all at once, and only the selectively called number can talk, other mobile stations or base stations can talk only on other channels, and the line being called is not used. Can not.

It is also assumed that the mobile station or base station that is selectively called to confirm the speaker sends a confirmation answer signal to confirm the other party.

Although the above embodiments have been described with respect to voice communication, a computer 8 is connected to the base station terminal 6 as shown in FIG.
Alternatively, as shown in FIG. 3, by connecting the line distribution function base station radio 5 and the extension telephone exchange 7, 5 and the base station terminal 6 through a dedicated line, and in the embodiment, a system in which there is only one base station 3 has been described, but the number of installed base stations 3 and the number of base station terminals 6 , there is no limit to the number of mobile stations.

[Effects of the Invention] As explained above, in this invention, since a selective calling device is attached to a base station and a mobile station, there is no need to verbally identify which station is being called, and efficient communication is possible. It has this effect.
