Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control method for a mobile telephone using a wireless line.

A mobile telephone system using a wireless line includes, for example, as shown in FIG. 1, an exchange 102 that performs switching connections with other telephone networks 101 such as a general fixed telephone network, and a wireless line control system that controls wireless equipment. device 103, wireless transceiver 104,
It is composed of an antenna duplexer 105, a base station antenna 106, a mobile station antenna 108, and a mobile station 109, and is configured to communicate between mobile stations or between a mobile station and a fixed station using a wireless line IOT. It is.

Incidentally, in recent years, various services such as a call waiting service have been implemented in general fixed telephones, and it is strongly desired that such new services be implemented in the above-mentioned mobile telephones as well. However, due to the special circumstances in which mobile telephones use radio circuits, the control method that is widely used in general landline telephones, i.e., the switchboard rule that determines when the telephone's hook switch is pressed down for a certain period of time, is The method of identifying the presence or absence of hooking by determining the presence or absence of hooking and performing a predetermined exchange connection cannot be applied as is. This is because instantaneous signal interruptions occur in the wireless section due to fading and other factors that occur as the mobile unit moves, and even if a mobile unit transmits continuous signals such as those from a regular landline telephone, the receiving side does not necessarily receive them continuously. This is because the logic becomes extremely complex. The present invention has been made in view of the above circumstances, and its purpose is to provide a mobile telephone control system that enables the realization of new services such as call waiting service even in mobile telephones using wireless lines. It is about providing.

The present invention provides a mobile telephone control system using a wireless line, in which a discriminating means is provided on the mobile telephone side to determine whether a hooking operation or a call termination operation has been performed by measuring on-hook time; When the determining means determines that a hooking operation has been performed, the hooking information indicating that fact is sent through a telephone line by a dedicated control signal, and when it is determined that a call termination operation has been performed, control is performed to perform call termination processing. A means is provided so that the switching device receives and identifies the hooking information and performs a predetermined control operation, and an embodiment thereof will be described in detail below. FIG. 2 is a block diagram of the main parts of a mobile telephone that implements the method of the present invention.
Connection system for wireless channel settings, calling/receiving, etc.
A control unit 202 that controls operations, and a wireless unit 203
and a mobile station antenna 204, and the handset section 201 is provided with a switch 205 and a dedicated switch 206 for sending control signals.

FIG. 3 is an operation flowchart when the control unit 202 of the mobile device measures the hooking time and makes a locking judgment, and identifies the necessity of sending a control signal and the presence or absence of a signal. This is how it is done. When a subscriber presses down the hook switch 205 of the handset section 201 during a call, the control section 202 measures the on-hook time, as shown in FIG. 3, and if it is longer than a predetermined time, the call is terminated. It is determined that the cutting process is performed, but if it is within a predetermined time, it is determined that the cutting process has occurred.

If it is determined that there is a hooking, a hooking signal in a signal format suitable for the wireless line, that is, a signal format with redundancy such as an error correction code, is transmitted to the base station via the radio section 203 and the mobile station antenna 204. sent to the station. 6. As the hooking signal, it is possible to use a tone signal or a digital signal. On the other hand, the radio line control device constantly monitors control signals sent through the telephone line, and when it receives a hooking signal, it relays it to the exchange via the control line.

The exchange receives and identifies the control information and starts a predetermined control operation. As can be seen from the above description, the present invention provides a control method for a mobile telephone using a wireless line.
A determining means is provided on the mobile telephone side for determining whether a hooking operation or a call termination operation has been performed by measuring on-hook time, and an indication to that effect when the determining means determines that a hooking operation has been performed. A control means is provided for transmitting the hooking information by means of a dedicated control signal through the telephone line and performing call termination processing when it is determined that a call termination operation has been performed, and the switching equipment receives and identifies the footing information. This system is designed to perform a predetermined limiting operation, and there is no need for the exchange to measure on-hook time to determine whether or not it is a hooking operation, so it is possible to use a wireless line with poor transmission conditions such as fading. Even in mobile telephones, there is an advantage that the hooking signal can be reliably transmitted during a call.

In particular, in wireless sections with poor transmission conditions such as fading, if a transmission method with redundancy such as multiple signal transmission method is adopted, control signals can be transmitted more stably and reliably, and stable control signals can be used. This will make it possible to realize new services that have
