Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a PA line terminal and a wireless communication system, and particularly to a wireless terminal having multiple reception modes and a wireless communication system using the same. [Prior Art] A local wireless telephone system that is an extension of the conventional cordless telephone is discussed in the 1986 National Conference of the Telecommunications Division of the Institute of Electronics and Communication Engineers, Nα438, pp. 2-256 (1986). The feature of this system is that cordless telephones were connected to a specific base station and could only be used in a narrow range, but now they can be connected to unspecified base stations under the control of a private branch exchange (PBX) and can be used anywhere within the premises. The point is that it can now be used freely from any location. By having each person always carry this kind of small traveling Mitt phone,
Calls can be made and received no matter where the person is stationed. This makes it possible to call any person using a wired telephone installed in a specific case, or directly call a specific individual using a wireless telephone. [Problem to be solved by the invention] When the owner is called directly using the above-mentioned Art1 telephone, the call is made and received at any location on the premises. Ringing (ringing!! IJ) calls occur even when there is no ringing. However, there are few cases where urgent calls are required, and a voice message (for example, from a trade guard telephone) is sufficient.
Furthermore, depending on the content, it is not necessary to use ALU communication, and in many cases, memory exchange is sufficient, so it is considered effective to use e-mail, etc. In addition to the current voice communication that involves ringing, by introducing such non-ringing communication, it will be possible to select a communication mode according to the time, place, and situation, eliminating unnecessary groaning. It can be reduced. It is necessary to switch between these communication modes and to control the prohibition level depending on the content of the meeting, but it is time-consuming to change these each time you move to a predetermined location by key personnel, and it is easy to forget to switch the communication mode. It can also be a cause. An object of the present invention is to provide a wireless terminal that automatically switches reception modes and a wireless communication system that uses the wireless terminal. [Means for Solving the Problem] In order to achieve the above object, the present invention provides a wireless terminal with:
It is equipped with a clocking means, a means for setting a schedule, and a reception mode switching means, and the reception mode is automatically selected according to the contents of the set schedule and the current time. The settings for the above schedule include, for example, the start time and end time of the conference, the conference room (location), the call restriction level to restrict the transmission mode in that conference room, and the incoming call restriction to restrict the reception mode. Use levels etc. In addition, in special areas such as conference rooms where it is necessary to restrict incoming calls in order to restrict free calls from other subscribers, the wireless base station in charge of this area transmits a base station identification signal (hereinafter referred to as , base station ID) with a preset restriction level for outgoing and incoming calls added, and the wireless terminal receives the signal according to the content of the set schedule and the content of the signal from the base station. Allow the mode to be selected. Also,
In that case, the wireless terminal uses the base station ID broadcast from the base station and the base station ID stored in the internal memory in advance.
1. From the position correspondence table, the current position is recognized, and from the reception mode determined based on the contents of the schedule or the reception mode determined based on the information from the base station, according to the current position. , select one of the reception modes. Additionally, if the current location and the location set in the schedule are different, the wireless terminal will output an alarm, or if it receives a predetermined emergency signal from the base station, it will change the reception mode selected as described above. Instead, a predetermined reception mode is selected. [Operation] The wireless terminal described above automatically selects the reception mode according to the current time and the contents of the schedule, eliminating the need for complicated reception mode switching operations. In addition, since the schedule settings include, for example, the start time of the meeting and the incoming call level to regulate the reception mode, it is possible to limit unnecessary calls during the meeting. Furthermore, since the wireless terminal outputs an alarm when the location set in the schedule at the current time differs from the current location, it can be useful for the owner's schedule management. For example, if the owner forgets to attend a predetermined meeting, he or she can be informed of this by an alarm from the wireless terminal.

〔Example〕

An embodiment of a wireless communication system to which the present invention is applied will be described in detail below with reference to the drawings. FIG. 1 is a schematic diagram of a wireless communication system to which the present invention is applied. Private branch exchange (PBX) 11 is a private branch telephone distribution I! It is connected to base stations 31-33 through 21-23. The subscribers have portable devices 41 to 43, and
43 is wirelessly connected to any of the base stations 3l to 33 during a call. In Figure 1, the mobile device 4l is connected to the base station 3

By receiving this signal, the mobile device can know which base station it is near, and which base station it can connect to during a call. The mobile device uses the base station ID included in this information and the t! ! Information including the ID of the 4-band device itself is reported to the private branch exchange each time the location changes.

This reported information is stored in the mass storage 13 through the control circuitry 2. As a result, private branch exchange 1
1 can know the location of the subscriber (portable device) and can select the correct base station when receiving a call to the subscriber.

Regulation based on signals from base stations (communication regulation based on location)
There are two types of restrictions: and restrictions entered by the user when setting the schedule (communication restrictions based on schedule). The communication mode that the portable device ultimately selects is either the reception mode determined based on the communication restriction based on the location described above, or the reception mode determined based on the communication restriction based on the schedule. Details will be described later in Figure 10. Communication restrictions based on location are
It is determined by the contents of the incoming call restriction flag and the outgoing call restriction flag included in the above-mentioned location information signal 200 (FIG. 2). Monitoring of communication restrictions based on this location and recognition of the current location are performed by the location monitoring program 306 (FIG. 4). This program 306 is activated when the modem 415 receives a location information signal from the base station. FIG. 6 is a flowchart of the position monitoring program 306. The number 1 received? ? The base station ID is detected from the Yuuhokou (step 601) and compared with the previous base station ID registered in the current location storage area (step 602). If different, the base station ID included in the received location information signal
is written to the current position storage area 504 (step 60
3). The base station ID is notified to the private branch exchange (step 604). The private branch exchange stores the notified base station ID as the ID of the base station currently available to the mobile device. As a result, the current location of the mobile device is registered both in the mobile device itself and in the private branch exchange. After this processing, the communication restriction flags 240 and 250 included in the position information signal are written into the position communication restriction flag area 509 of the communication restriction flag storage area 505 (step 605). On the other hand, restrictions based on schedules are performed by the user setting the content of communication restrictions when inputting the schedule. Figure 7 shows
It is a diagram illustrating an example of scheduling manual effort and regulation level settings. In this example, the first conference room will be open from 10:00 to 12:00.
:00, incoming calls are restricted to non-ringing communications, and outgoing calls are restricted to non-voice communications. As shown in Figure 8, the communication mode related to regulation is determined by the communication regulation level, such as ringing communication, non-ringing communication, voice communication, and non-voice communication. For example, e-mail with ringing is a mode in which a ringer sounds as soon as an e-mail is received. E-mail is also used to communicate address books, schedules, and base station IDs.
Refers to a digital text communication mode such as one-position correspondence table communication. FIG. 9 is a diagram showing the structure of the communication restriction flag storage area 505 in the RAM 423. The communication restriction flag is the 9th
As shown in the figure, the incoming call restriction flag and the outgoing call restriction flag consist of three flags: an incoming (outgoing) prohibition flag, a ringing prohibition flag, and a voice communication prohibition flag. The incoming (outgoing) call prohibition flag 91 indicates that no incoming (outgoing) calls will be accepted, and the ringing prohibition flag 92 prohibits communication with ringing such as phone calls, e-mails with ringing, and voice calls as shown in FIG. The communication prohibition flag 93 indicates that communication by voice such as phone calls and voice messages is prohibited.

Regarding the relationship between ``communication restriction based on location'' and ``communication restriction based on schedule,'' for example, as shown in FIG. 10, if there are both communication restrictions, priority will be given to restriction based on schedule. However, even if communication restrictions are set in a schedule such as a meeting schedule, if for some reason you are unable to go to the appropriate location at the scheduled time, it is desirable that the communication restrictions based on the schedule are not applied. Therefore, if you are not at the specified location at the time set in the schedule, priority will be given to "location-based communication regulation" at that location.Next, we will explain the operation flow when receiving a call using Figure 11. explain.

When the portable device 4l receives a signal requesting an incoming call from the wireless base station, it starts the incoming call control program 305.

In step 700, it is determined whether to read the communication restriction flag (incoming call restriction flag here) used to determine the communication mode from the location communication restriction flag or the scheduled communication restriction flag, based on the schedule specified position and the current position information. Details will be explained later using Figure 12. If the communication mode determined in step 700 is a mode that prohibits all incoming calls (incoming call prohibition mode), the caller is notified of the incoming call prohibition mode (step 711). Other communication modes (communication modes, etc.)
If so, the program advances to the next step (step 710). Next, it notifies the calling side of the communication mode (step 712), waits for a response signal from the calling side,
After receiving the response signal, proceed to the next step (step 712). If the requested communication mode included in the response signal from the caller is the emergency communication mode (described later in FIG. 13), the communication mode of the mobile device and the requested communication included in the response signal from the caller are The program proceeds to perform any communication (steps 717, 719, 721, 723) without checking the mode (step 714). In step 715, the communication mode mentioned above is checked,
If they do not match, the caller is notified that the call will not be received (step 724). Terminate the process. If the communication modes match, the communication modes are determined in steps 716, 718, 720, and 722, and the respective communications are performed (steps 717, 719, 721, and 7).
23) , then end the process (step 725)
．． FIG. 12 shows step 70 of the program 305 described above.
0 is a diagram showing a detailed flowchart of 0. In step 701, it is checked whether communication restrictions are set in the schedule at the current time.

As a result of checking in step 701, if communication restrictions are set, the location set in the schedule is compared with the current location (step 702). As a result of the above-described location verification, if they match, the communication restriction set in the schedule is adopted as the incoming call restriction (step 706).
If they do not match, proceed to the next step 703. Also,
As a result of checking in step 707, if communication regulation is not set, the signal 220 (second circle) from the wireless base station
It is checked whether communication restrictions are set (step 703).

From the result of step 703, if there is a so-called "location-based communication restriction," position-based communication restriction is adopted as the incoming call restriction (step 705). (Step 7
04). FIG. 13 is a diagram for explaining the exchange of signals between the calling side and the called side in steps 712 to 713 (FIG. 11). The communication mode of the called party is communicated to the calling party,
If the communication mode initially requested by the caller is possible, a communication start signal will be automatically issued from the caller, but if there is no communication mode available, the caller's display will change to a communication mode in which the call can be received. change requests are displayed. On the other hand, if the caller selects a restricted communication mode, the callee will forcibly terminate the communication. but,
If it is deemed to be an emergency, the caller must press key 427.
By pressing the restriction release key located on the terminal, a signal indicating that the call is an emergency call is added to the communication start signal, making it possible to receive calls without incoming call restrictions. However, in order to avoid abuse, this key is activated only once after receiving the communication mode request signal shown in FIG. 13, and is valid only once for that communication. In the present invention, by using current location information and schedule information, the present invention has a function of issuing an alarm to the owner if the vehicle is not at the corresponding location at the time set in the schedule.

If you turn on the location call as shown in Figure 7 when entering the schedule, if you are not in the first conference room at 10:00, it will sound and appear on the display, but if you are in the corresponding conference room, no alarm will be issued. This not only lets you know if you have forgotten to participate in a meeting, but also reduces unnecessary noise in the conference room.

This function is performed by the schedule check program 310 and is shown in FIG. step 80
At 0, the current time is read from the clock 425 into the memory 423.

Checks whether the current time matches the time set in the schedule (for example, the start time of the meeting in Figure 7).
Step 801), if they do not match, the process ends; if they match, proceed to the next step 802. In step 802, in the applicable schedule,
Determine whether an alarm is set. This alarm may be set by separately providing a switch in the portable device and turning the switch ON/OFF, or, as explained in Fig. 7, when setting the schedule, the "Position Call" Create another setting field in addition to
You can also set it here. If an alarm has been set, proceed to step 803; if no alarm has been set, proceed to step 80
Proceed to step 7.

In step 803, it is determined whether "ON" is set in the "location call" column of the corresponding schedule, that is, whether a check alarm based on location is set. If a position-based check alarm is not set, an alarm is output for a predetermined period of time and a message to that effect is displayed on the display (step 806). If a position-based check alarm is set, read the current position (
Step 804), and the read current position is compared with the position set in the schedule (Step 805). If the matching results are different, proceed to step 806; if they match, proceed to step 80 without outputting an alarm.
Proceed to step 7. In step 807, the incoming call is received according to the schedule, the reception restriction flag is set, that is, the communication mode is set, and the process ends (return).++This schedule check program is periodically executed by an interrupt generated by the interrupt timer 424. It will be done. The conference organizer will notify the participants of the event via email or schedule communication. If the contact is made via scheduled communication, it can be set to ring if the user is not in the conference room, as described above. In addition to this, 9.
By recording the meeting, if all participants are not in the meeting room at the time of the meeting, an e-mail with a ringing mode will be automatically sent. Or send the voice stored in the automatic call voice message circuit in normal voice call mode. This can improve meeting attendance rates. [Effects of the Invention] According to the wireless communication system of the present invention, it is possible to realize a wireless terminal that can automatically switch reception modes. Specifically, mobile wireless terminals have multiple communication modes,
Since this can be automatically switched as necessary, it is possible to reduce the number of calls for communications of low importance during meetings, etc., and it is possible to reduce the number of calls for communications of low importance during meetings, etc., and to communicate necessary content through non-ringing communications such as v#1 child mail and voice messages. I can tell you. Furthermore, by automatically switching communication modes based on the schedule and current location, there is no need for complicated communication mode switching operations that change depending on the situation, increasing convenience and preventing forgetting to switch modes. Additionally, since it will notify you that you will not be at the scheduled time at the location indicated in the schedule, you will be able to prevent forgetting to participate in the conference room.

Furthermore, by automatically sending the base station ID-location correspondence table required to obtain location information from the private branch exchange, it is possible to eliminate the need for manual input every time there is a change.
