Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile telephone, and more particularly to a mobile telephone used in a microcell portable telephone system, a cordless telephone system in a premises, etc., which can be interconnected.

In the past, one mobile phone (portable station) could not be commonly used in homes, offices, and public systems, so in recent years, domestically connectable mobile phones are available. As a system, a PHP (Personal Handy Phone) concept and an overseas system (CT-2) have been invented and are being used, but the dial tone or ring tone of a mobile phone in such a system is made different. Is desired.

[0003]

2. Description of the Related Art Conventionally, the following two methods are known as methods for transmitting a dial tone to an operator in a mobile telephone.

(1) The first method is to send a dial tone to the mobile telephone from the exchange side to which the base station (Cordless Set) is connected, similarly to the analog wired telephone. In this method, when a call request signal is sent from the mobile telephone side to the exchange side via the base station, the exchange side determines the call request of the mobile telephone and sets it in advance to the exchange side for sending at call origination. This is a method of transmitting the reserved tone to the mobile telephone side.

In the system operated by the first method, the exchange device uniquely determines the dial tone to be transmitted. For example, in the public network, this dial tone is set to 400 Hz continuously, and in the PBX (Private Branch Exchange), in order to identify whether the caller is using an extension line or an external line (public network line), the former The tone is set to a tone different from the latter (for example, intermittent 400 Hz, continuous 800 Hz, etc.).

(2) The second method is a method in which dial sounds are collectively sent from the telephone side to the operator, which is the same method as the preset calling in the ISDN telephone or the conventional analog telephone. That is, in ISDN, since the "Called party number" information element designating the communication partner of the call is included in the "Call setting" message transmitted at the time of calling, the operator's operation is
After entering the dial number, press the dial (or call) button to enter the batch dial method, and when the dial button is first pressed, a pseudo dial tone (not from the exchange itself) will be sent from the phone itself, and the dial number will be entered. There is a conventional dial input method in which a "call setting" message is sent to the exchange body when a certain time has elapsed.

[0007]

In the system operated by the above-mentioned second method, the telephone to be connected is directly accommodated in the public network (direct public network accommodation) and is accommodated in the PBX. Since the dial tone is the same for (PBX accommodation), the accommodated telephone cannot autonomously recognize it, and the telephone itself does not have a function for recognizing direct accommodation and PBX accommodation. This also applies to ringtones.

For this reason, the telephone user has to confirm by himself whether it is a direct public network accommodation or a PBX accommodation. For example, in the case of PBX accommodation, "0" is first inserted to make a call. Operation is required, and if it is neglected to use it, the service is deteriorated, such as erroneous connection, erroneous determination as a failure, and work such as calling maintenance personnel.

This will be explained below by taking the above-mentioned PHP mobile telephone system as an example. FIG. 9 (a) shows an example of a zone configuration between the mobile telephone systems when a plurality of business office systems exist. For example, as shown in the figure, it is assumed that two base stations CSa and CSb are installed on the floor of the building X and their wireless zones Za and Zb overlap each other. Let Zc be the wireless zone of the base station CSc of the installed mobile telephone system.
These base stations CSa, CSb and CSc each accommodate PBX as shown in FIG.

Further, the wireless zone of the base station CSd directly accommodated in the public network, which is connected to the mobile exchange EX for the public network installed at the adjacent outdoor place, is designated as Zd and the wireless zones Za and Zb are shown in FIG. It is assumed that they overlap as shown in.

When the mobile telephones PS are connected to each other in the overlapping radio zone portions and used, the dial tone or the ring tone cannot be set differently depending on whether the telephone is directly accommodated in the public network or accommodated in the PBX. In this method, when the user has not used the mobile phone for a while and forgets which system the user is trying to use, it is necessary to perform a troublesome operation such as checking the settings of the mobile phone.

Therefore, the present invention has been made in view of the above problems, and the notification information by the control carrier from each base station is periodically received intermittently between a plurality of mobile telephone systems by a plurality of base stations. It is an object of the present invention to improve a user's service by making a call or receiving a call to a system desired by a user in a mobile phone that enables connection.

[0013]

FIG. 1 shows the principle of a mobile telephone according to the present invention for achieving the above-mentioned object. Input setting for setting dial tone data for each system. Means 1 and system selecting means 2 for selecting a system to be used from the systems in which the data is set
A means 3 for collecting the notification information, a tone creating / sending means 4, a system selected by the system selecting means 2 and a system indicated by the notification information collected by the notification information collecting means 3. Only when they match, the control means 5 is provided with tone data corresponding to the system to the tone creating / sending means 4 to send the tone.

In the above-mentioned present invention, the input setting means 1 sets the ring tone data instead of the dial tone, and the tone creating / transmitting means 4 creates the ring tone instead of the dial tone and sends it. can do.

[0015]

In FIG. 1, in the mobile telephone, data of a dial tone or a ring tone specific to each mobile telephone system is input and set by the input setting means 1 in advance.

On the other hand, the base station accommodated in each mobile telephone system uses the control carrier to intermittently transmit known broadcast information including radio channel information, system information, system information and the like at regular intervals. The mobile telephone waits for any of the base stations by the notification information collecting means 3.

When the user selects a system to be used from the mobile telephone systems set as described above by the system selecting means 2, the mobile telephone uses the selected system and the notification information collecting means 3. The control means 5 compares the system indicated in the notification information.

The control means 5 causes the tone creating / transmitting means 4 to send out a dial tone or ring tone corresponding to the system to the user only when the coincidence is detected.

In this way, it is possible to make an outgoing or incoming call in the mobile telephone system desired by the user without error.

Is composed of a main controller 17.

FIGS. 3 and 4 are flowcharts showing a dial tone / ring tone control algorithm for each system of the embodiment of the mobile telephone of the present invention shown in FIG. 2. The embodiment will be described below based on this flowchart. The operation of will be described.

First, the mobile phone (PS) is turned on (step S1), and radio channel information / system information /
Broadcast information such as call information and regulation information is provided by a base station (not shown)
Put it in a state of receiving intermittently from.

The broadcast information from the base station will be briefly described with reference to FIGS. 5 to 7. FIG. 5 shows the allocation of carriers and time slots. One frame is divided into 4 slots each in the direction from the telephone to the base station) and in the downlink (from the base station to the mobile telephone), for a total of 8 slots.
As frequencies for upstream and downstream control slots CR (reception of control data) and CT (transmission of control data), a common control frequency fa is used by both the business / home mobile telephone PS and the base station CS.

Further, the carrier for communication has frequencies fb ...
Among fn, those not used by other base stations or mobile phones are assigned at the time of starting a call in time slot units. This is similar to the current multi-carrier access method for analog cordless phones.

Further, the downlink control slots CT transmitted by the respective base stations CS are shifted from each other at a certain period as shown in FIG. 6 in order to avoid frequency collision with the adjacent base stations. Intermittent transmission is being performed.

As the control slots CT sent from each base station CS to the mobile telephone PS at the periodic intervals shown in FIG. 6, as shown in FIG. Broadcast information channel BCCH (see FIG. 8) for information, call information, regulation information, etc., incoming call information channel PCH for the incoming call group allocated in advance for each mobile telephone, and call carrier (frequency) / for the incoming mobile telephone / The slot allocation information channel SCCH (see the same figure) is included.

As for the control slot, as shown in FIG. 8, different originating identification codes are set for each system of BCCH, PCH, and SCCH.

Next, the operator selects whether to use his or her mobile telephone as a call mode or a data setting mode by closing the mode changeover switch SW (step S2), and first, the latter data setting mode. Therefore, the identification (ID) number of one or more systems to be used in the future and the data of the dial tone / ring tone used in the system are input as individual data from the ten-key input unit 14 (steps S3 to S6). .

As a result, the main control section 17 reads the setting data and edits and stores the data in the dial tone / ring tone data storage section 15 (step S7).

After the data setting is completed in this manner, the call mode is selected by opening the mode selector switch SW, and the operator selects the mobile radio telephone system to be used from the ten-key input section 14 (step S8).

The main control unit 17 determines whether or not the setting data for the selected system is stored in the dial tone / ring tone data storage unit 15 (step S9), and the setting data is still as described above. When it is not stored, the process returns to step S2 and is repeated, but when it is already stored, the data is stored in the used system selection data storage unit 16 (step S10).

After that, the base station CS executes the process of collecting the broadcast information which is intermittently transmitted as described above (step S1).
1).

The mobile telephone PS then receives the control channel information received from the base station CS from the demodulation unit 12 in the radio unit 12.
It is received by the TDMA control unit 13 via 2 and read by the main control unit 17.

The main controller 17 compares the system identification number (see FIG. 8) in the read control channel information with the system identification number in the system data used by the operator (step S12), and the mismatched systems are detected. The identification number is discarded, only the matching data is selected, and the process proceeds to the outgoing / incoming call processing (step S13).

The electric field strength of the carrier of the control channel is measured by the received electric field strength measuring section 123. Main controller 1
Reference numeral 7 determines a base station capable of intermittent reception from the base stations transmitting the control channel information that matches the data from the reception electric field strength measuring unit 123. The logic to be determined may be a base station having the strongest electric field strength, or a random number determination method so as to scatter the number of mobile phones waiting. In this way, the mobile telephone collects the notification information transmitted by each base station capable of intermittent reception.

When step S13 is a calling process, that is, the process proceeds to step S21 in FIG. 4 (a), and then step S2.
When it is confirmed in 2 that the operator has pressed the send button PB, the ten key input unit 14 notifies the main control unit 17 of the send button press information.

The main control unit 17, which has received the call button pressing information, reads the system data to be used from the system selection data storage unit 16 to be used and analyzes the data, and then outputs the tone / ring tone data of the system used by the mobile telephone. The tone data corresponding to the dial tone of the corresponding system is read from the stored dial tone / ring tone data storage unit 15.

When the main control section 17 sets the read tone data in the tone creating section 18, the tone creating section 18 creates a dial tone corresponding to the set data and sends it to the tone sending section 19. Tone transmitter 19
Causes the tone created by the tone creating unit 18 to be amplified and made available to the operator.

In this way, the operator of the mobile telephone confirms that the mobile telephone system to be called is the same, for example, whether the system is a public network direct accommodation system or a PBX accommodation system. It can be confirmed by the dial tone.

On the other hand, in the case of the incoming call processing in step S13 (step S31), the notification information from the base station is received by the TDMA control unit 13 via the demodulation unit 122 in the radio unit 12, and the main control unit 17 And the system identification number in the notification information is matched with the system identification number selected in step S8 (step S32), and only when they match, step S2
Similar to 3 and S24, a desired ring tone is sent to the operator of the mobile telephone.

In this way, the operator receives a ring tone only from the extension system or the outside line system he / she desires to make a call.

The operator needs to know the above dial tone or ring tone in advance.

When the system used is changed,
By inputting the used system selection data from the ten-key section, the data in the used system selection data storage section 16 is rewritten, and different dial tone / ring tone can be sent to the user by the same processing as described above. it can.

[0045]

As described above, according to the present invention, dial tone data or ring tone data is set for each system.
When both of them select the system they want to use, only when the system and the system indicated in the broadcast information from the base station match, the dial tone or ring tone corresponding to the system is created and transmitted. Since it is configured as described above, there are effects such as improvement of operability for the user, reduction of erroneous connection, and reduction of wasteful labor for misjudging a failure.
