Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a peripheral zone radio channel reservation system and a reservation method capable of preliminarily reserving radio channels of another radio zone when a certain radio zone is congested in mobile communication.

[0002]

2. Description of the Related Art In wireless mobile phone technology such as mobile communication that has been generally known so far, a communication service area is divided into a plurality of wireless zones (also called cells).
In many cases, a wireless base station is arranged in each wireless zone. In the case of the wireless mobile phone technology having this configuration, the telephone subscriber can perform communication by registering the location with the wireless base station in the existing wireless zone and off-hooking to secure the wireless channel. Become.

The capacity of the radio channel assigned to each radio base station is generally fixed.

By the way, there is an invention disclosed in Japanese Unexamined Patent Publication No. 2-262729 as a method of priority connection or reservation connection of a telephone. In this method, when a call channel is not available, a reservation operation is performed to wait until a call channel becomes available, and a call is made when the call channel becomes available.

[0005]

However, there is a physical limit to the number of wireless channels that one wireless zone has, and there is a huge number of wireless channels such as stations and shopping districts where people are concentrated. If a connection request occurs, the wireless zone will be saturated immediately.

A person who wants to make a call from a wired public telephone can grasp the present queue by visually observing the queue of persons who are visually arranged in front of the public telephone. Therefore, those who want to make a call quickly can move their traffic to a public telephone that is as free as possible and make a call by themselves to distribute the traffic to the public telephones nearby. Came.

On the other hand, in the case of a wireless telephone, unlike this,
Since people who want to make phone calls do not line up in a certain place and form a queue, people can not grasp the queue, and if only the relevant wireless zone is crowded, there is no space around There is a first problem that it is completely impossible to grasp whether or not there is a wireless zone in which there is.

[0008] Therefore, since the user does not voluntarily move to the surrounding wireless zone (although it is possible that he / she tries to make a call by disorderly moving), the behavior of the user. There is a second problem in that the effect of distributing traffic cannot be expected.

Therefore, an object of the present invention is to visually inform the user of the usage status of wireless channels in the wireless zone.

Further, the present invention aims to promote the action of distributing traffic by the voluntary action of the user.

On the other hand, even if the user is visually informed of the usage status of the wireless channels in the wireless zone and the user is encouraged to voluntarily disperse the traffic, the user moves to a vacant wireless zone. In doing so, there is a third problem that another user makes a call first, and when the moving user tries to make a call, all the wireless channels are already blocked.

Therefore, it is an object of the present invention to provide a wireless channel reservation system that can reliably make a call by reserving a wireless channel in a target wireless zone in advance before moving.

Further, according to the present invention, as one of means for solving the first problem, there is a configuration for transmitting a peripheral map of the wireless zone where the user is located to the wireless terminal of the user, but the map information is generally used. In addition, since there is a large amount of information because it is image information, there is a fourth problem that the configuration for transmitting map information becomes complicated and expensive accordingly.

In view of the above, the present invention provides a configuration for effectively utilizing existing resources while maintaining compatibility with existing telephone systems, so that the present system can be introduced quickly and at low cost. And

By the way, generally, the map information tends to have a large data size, and accordingly, the image processing such as synthesizing the use condition of the wireless channel on the map requires a considerable computing capacity. There are challenges.

Similarly, since the map information has a large amount of information, there is the sixth problem that the transfer time to the wireless terminal is long.

Therefore, it is an object of the present invention to provide an efficient system in which map information processing can be processed by a portion having a computing device with a computing capability as high as possible.

Furthermore, the present invention aims to improve the transfer time of the map information transfer time.

By the way, according to the present invention, the wireless channels of the peripheral wireless zones can be reserved in advance. However, if this reservation is possible without any restriction, useless reservation will be unnecessarily invited. As a result, the number of unused channels secured by the reservation is increased, and there is the seventh problem that traffic congestion is rather caused.

Therefore, the present invention has a configuration for forcibly canceling the reservation after a certain period of time has passed since the reservation in order to limit the unnecessary reservation, and also while the wireless channel is reserved by the reservation. It is an object of the present invention to provide a wireless channel reservation system that slightly collects a fixed fee.

Wireless base station 13
In 06, the received map information is attached to the wireless channel information and transmitted to the wireless terminal 1308. The advantage of this configuration is that the system can be easily introduced into the existing system and that it can be easily maintained. As a drawback, the time required to transfer the map information to the wireless base station cannot be ignored. However, the wireless base station may be provided with a memory such as a large capacity buffer, and once the wireless base station receives the map information from the position information control station, it may be stored in this buffer and transmitted to the wireless terminal as necessary. . On the other hand, when the map is updated due to maintenance of the position information control station 1302 or the like, if the latest map is transmitted to the buffer of the wireless base station 1306 again, it becomes possible to prevent unnecessary information transfer.

It is advantageous in terms of cost because it can be managed at. On the other hand, in this method, each time a map information transmission request is made to a wireless terminal, the map information is transmitted via the line network-switching station-radio base station, which is wasteful in terms of time. In addition, there is a drawback in that a communication line is wasted because a line for transmission must be secured.

Therefore, as shown in FIG. 15, the map information is stored on the CD-
If the wireless base station 1501 is provided with a storage device such as a ROM, a hard disk, or a memory, the system can be inexpensively configured due to the cost reduction effect of mass production of the wireless base station and the storage device. The detailed operation sequence will be described later with reference to FIG.

The system may utilize a road traffic information system as shown in FIG. In this case, the road traffic information providing station broadcasts road congestion status and map information by radio waves. This broadcast map information is transmitted to the wireless base station 160.
A case of broadcasting to the wireless terminal 1602 via H.4 will be described. The wireless base station has a receiver for receiving the radio waves transmitted from the road traffic information system, and the control device of the wireless base station is configured to convert the map information into data receivable by the wireless terminal. . Further, the control device provided in the radio base station may store the radio base station channel information in a memory, map it on this map, and then transmit it to the radio terminal.

Next, the wireless terminal 160 displays the road congestion status and map information broadcast by radio waves from the road traffic information providing station.
A case will be described where 2, 1603 directly receives. The wireless terminals 1602 and 1603 include receivers for receiving map information. This receiver may share the receiver used for communication with the wireless base station 1604. Also, the control device of the wireless terminal synthesizes and displays a channel meter, which will be described later, on the map based on the position information and the wireless channel usage information transmitted from the wireless base station.

Further, the terminal itself may be provided with map information as shown in FIG. In this case, the control device of the terminal receives position information such as latitude and longitude from the wireless base station in order to know the existing position of the terminal itself. Next, the control device searches the received positional information such as latitude and longitude for the map information 1702 stored in the storage device based on the wireless base station. Then, the last searched map is displayed on the display device. Here, the map information may be stored in a storage device in the terminal, or may be connected to an automobile navigation system through an interface to use the navigation map information.

The system and device configurations have been described above, and the operation of the radio channel reservation system having these configurations will be described below. The wireless base station 1
There are four wireless terminals 101 in the service area 104 of 06, and all of them are in communication. Further, in the service area 105 of the peripheral wireless base station 107, it is assumed that only the wireless terminal 103 is in the communication state and three channels are vacant. Note that this system can be applied to other systems such as a time division multiple access system or a code multiple access system as long as it is a multiple access system. In that case, the configuration of the channel codec unit, the modulation / demodulation unit, the high frequency unit, etc. may be adapted to the connection system.

First, the operation when the wireless terminal 102 located in the service area 104 performs location registration with the wireless base station 106 will be described with reference to FIG.

First, in step 1802, the radio base station 10
6 broadcasts position information and receives the wireless terminal 102.
Compares the position information stored in its own storage unit with the received position information in step 1803, and if they are different, in step 1804 the wireless terminal 102 to the wireless base station 1
A position registration signal is sent to 06. Next, a position registration signal converted into a form necessary for exchange connection is sent to the position information control station 112 via the exchange station 110 to which the wireless base station 106 is connected, and the position registration control by the position information control station 112 is performed. Registered in the database of.

As another position registration method, instead of notifying the position information from the wireless base station 106, when the position information registration trigger key provided in the wireless terminal is pressed or the power is turned on. Then, the wireless base station 106 that automatically issues a position registration request signal to the wireless base station and receives the signal is sent to the position information control station 112 connected to the public network or the like via the connection device 109 and the switching center 110. , A position registration request signal from the wireless terminal 102 is transmitted, and in the position information control station 112, the control device 1103 searches the position information database 1201 to determine whether the wireless terminal is a new wireless terminal that has moved from another wireless area. If it is new, the contents of the database 1201 are rewritten. Here, the position information registration trigger key may be input from a key on the keypad or may be input from a dedicated key by providing a dedicated key, but in any case, the control device is triggered. Determine that

When the location information control station 112 is thus registered, the wireless terminal 102 is notified as in-range information that the wireless base station 106 is within the service area in steps 1803 and 1804.

Here, in the present system, (a) when notifying the area information at the time of position registration (b) when the wireless base station regularly broadcasts the position information (c) the wireless channel usage condition from the wireless terminal (D) When making a call from a wireless terminal, by sending the current usage status of the wireless channel to the wireless terminal, the traffic of the current service area is sent to the user of the wireless terminal. It is possible to inform.

Specifically, the number of wireless terminals in communication with the wireless base station 106 is known by the wireless base station 106, the switching center 110, or the like, and the wireless base station 106 regularly broadcasts position information. When the information is transmitted, or when the in-range information is notified, or when the wireless terminal requests the transmission of the wireless channel usage status, the wireless channel usage status at that time is transmitted to the wireless terminal. In this case, not only the wireless channel usage status of the wireless base station 106 with which the wireless terminal 102 can directly communicate, but also the wireless channel usage status of wireless base stations around the wireless base station 106 may be notified. Here, the data to be notified is at least the ID (Identification) of the wireless base station or the service area.
n: authentication code) and the number of wireless channels used may be a set of data. Further, not only the number of wireless channels actually used but also the number of reserved wireless channels may be notified. In this way, even if all the wireless channels of the wireless base station 106 are blocked, the surrounding wireless base stations can know that the wireless channel is free, so the user of the wireless terminal 102 can access the wireless base station. It is possible to make a call by moving to the service area 105 of the station 107.

Next, a method of collecting and managing radio channels will be described in detail with reference to FIGS. The usage status of the wireless channel is either when the communication state of the wireless base station 106 or the wireless base station 107 located around the wireless base station 106 changes, periodically, or when a request signal is received from the exchange. In this case, the control device 711 of the radio base station
Searches the operation management information stored in the storage unit 712 and notifies the exchange station 110 of the current use status of the wireless channel.
Subsequently, when the wireless base station 107 notifies the switching center 110 including the switching center 110 and the like of the wireless channel usage status,
The control device 907 of the exchange station acquires the ID of the wireless base station from the sent information, and the wireless base station information table 1 stored in the storage device 908 from the ID of this wireless base station.
003 is searched and the changed information is updated.

In addition, as shown in FIG.
If 3 is under the control of another switching center, switching center 11
0 updates the wireless base station management table 1003 by having the exchange 206 transfer the usage status of the wireless channel of the wireless base station 203 via the line network 111. Also,
As described above, the communication may be performed directly using the communication line 204 between the wireless base stations without going through the exchange.

Here, the wireless base stations to be managed by the wireless base station information table are not only those under the control of the exchange station, but also the wireless base stations immediately outside the outer circumference surrounding the group of base stations under the control of the exchange station. Should be managed at a minimum. This considers the continuity of the map.

As described above, in the present system, since the exchange station or the radio base station collects and manages the radio channel usage status of the peripheral radio base stations, it is possible to immediately make a call to a user in an emergency. In addition to being able to teach possible wireless base stations, it also has the effect of distributing traffic by the user's voluntary action, such as a wired public telephone, without concentrating traffic only on specific wireless base stations. It is a thing.

Further, in the radio channel reservation system of the present invention, not only the user is informed of the use status of the channels including the peripheral radio base stations as described above, but also the radio channels of other radio base stations 107 are notified in advance. , Radio base station 10
It is possible to make a reservation while staying in the service area 104 of No. 6. Therefore, it becomes possible to connect an emergency call more reliably.

FIG. 2 shows a radio channel reservation system of the present invention. The present radio channel reservation system is a case where the configuration described in FIG. 1 is partially different, and specifically, a case where a peripheral radio base station 203 is connected to a switching center 206 different from the switching center 110. In this case, the reservation route becomes slightly complicated, but the basic reservation operation does not change.

In this case, the contents of the radio base station information table held by the respective exchanges are transmitted and received in real time, so that the latest radio channel use states are constantly updated.

Next, the radio channel reservation method of the adjacent radio base station will be specifically described. A particularly excellent feature of the present invention is that the service area 104 in which the user is located cannot directly access (however, a plurality of wireless base stations can be accessed in an overlapping area such as a boundary between service areas). ) It is possible to reserve the wireless channel of the wireless base station 107 in the vicinity.

First, a case will be described with reference to FIG. 19 in which the exchange has map information and a radio channel is reserved through a route of radio base station A-exchange station-radio base station B. First, the large step 1931 is a step of location registration, and step 19
It consists of 01 to 1904. In step 1901, the wireless terminal 102 notifies the wireless base station 106 of the position information stored in the storage device 511, and in step 1902, the wireless base station 1
06 sends the position information to the position information control station 112 via the exchange. In the position information control station 112, the control device 1103
Searches the location information database 1201 for the location of the registered wireless terminal (specifically, the ID of the wireless base station)
However, I of the wireless base station 106 that has transmitted the position information this time
It is compared whether it is the same as D, and if different, the contents of the database are rewritten. In this way, when the contents of the database are rewritten, steps 1903, 1
904 transmits the ID of the wireless base station that the wireless terminal is currently accessing via the exchange and the wireless base station.
In the wireless terminal receiving the ID of the wireless base station, the storage device 5
The ID of the wireless base station is stored in 11. This position registration step may be a large step 1831 shown in FIG.

Next, the accessing radio base station 106
Step 1932 of notifying the wireless channel usage status of
Will be described. The control device 711 of the radio base station manages the radio channel usage status in the radio channel management table stored in the storage device 712. For example, the control device 7
As a result of 11 searching the management table, the wireless base station 10
If there is no vacancy in the wireless channel No. 6, a line-free notification is transmitted to the wireless terminal in step 1906. This line availability notification may be sent together with the in-area information notification in step 1904, or may be configured to be notified when the wireless terminal 102 makes an off-hook m call or makes a call. On the other hand, if there is a free radio channel, the large step 1932 is omitted because communication with the radio base station 106 can be made immediately.

Next, a large step 1933 for transmitting map information will be described. Here, as described above, the transmission timing of the map information is (a) when notifying the area information at the time of position registration, (b) when the wireless base station regularly broadcasts the position information, and ) It has already been explained that there are cases where the wireless terminal requests transmission of the wireless channel usage status, and (d) when the wireless terminal makes a call, but here we explain the large amount of map information. Considering this, the case of sending at the time of the request of the user (c) will be described. Step 1
At 907, the control device 510 of the wireless terminal is the keypad 5
When detecting a map information transmission request trigger input from the device 13, the touch panel 601, or the like, the control device 510 of the wireless terminal next transmits a peripheral map request signal to the wireless base station 106. Here, the map information transmission request trigger is (d)
The calling operation may be performed, or the power may be turned off or the wireless terminal may be turned on. When the wireless base station 106 receives the surrounding map request signal from the wireless terminal in this way, the wireless base station 106 requests the surrounding map from the exchange 110 having the map information in step 1908. In the exchange 110 which has received the request for the peripheral map, the control device 907 stores the map information 1004 stored in the storage device 908 based on the ID of the wireless base station A 106 included in the request signal.
From, a map around the wireless base station 106 is searched and selected.
In step 1909, the exchange 1 which received the request for the surrounding map.
10 transmits the map information selected by the control device 907 of the exchange to the wireless base station 106 that has made the request. Further, the radio base station management table of the exchange station manages information for constructing an optimum map for each radio base station. The information to be specifically managed includes the location of the wireless base station, the size of the map, and the like.

By the way, in the case of periodically broadcasting the map information of (b), as shown in a large step 1832 of FIG. 18, the control unit 711 of the radio base station manages the time in advance and regularly transmits the map information. To broadcast.

Large step 1934 shows the mapping of the channel meter to the map information and the sending to the wireless terminal. Detailed processing of mapping will be described later. In step 1910, channel information of wireless base stations in the vicinity is further mapped. Here, the mapping is exchange 1
You may go at 10. This mapping is performed by the control device 711 of the wireless base station, and is specifically an operation of synthesizing a channel meter on the map. For example, overlaying map information with multiple layers of image information (eg, overlaying road information layer, traffic light information layer, building information layer, etc.).

In the above configuration, the wireless channel information such as a channel meter is also configured as one piece of image information of such layered images. The data below the channel meter is stored in the wireless base station information table 1003 stored in the storage device 908 of the exchange, and a similar information table is installed in the storage device of the wireless base station. Download from the exchange regularly or when needed. The contents of this information table include data such as the wireless channel usage status of each adjacent wireless base station including the own station. The control device 711 configures a channel meter based on this. Then in step 1911
Then, the mapped map is transmitted to the requested wireless communication terminal 102. In step 1912, the wireless terminal 102 that has received the map information sets the control device 510.
In the step (3), the image information is converted into image information that can be displayed on the display unit 512 and displayed on the display unit 512. Here, the user is
Based on the map information displayed in 2 and the use status of the wireless channel, it is possible to know the currently available wireless base station. Then, in step 1913, the desired wireless base station 1
07 is selected from the keypad or the touch panel.
When the controller 510 detects the key trigger, step 1
At 914, the wireless terminal 102 sends a signal to the wireless base station 106 to the wireless base station 106 by placing a signal on the control channel to reserve the wireless channel of the wireless base station 107. Specifically, the reservation notification data 2001 transmitted at the time of reservation includes the wireless terminal ID 2005 and the reservation destination wireless base station B as shown in FIG.
ID 2006, a reservation type 2007 indicating whether it is a priority reservation or a general reservation, a reservation reference number 2008 issued for each reservation, and the like. The reason why the priority reservation and the general reservation are provided as the reservation types is that it is necessary to preferentially connect outgoing calls in an emergency. Next, in step 1915, a signal for reserving the wireless base station 107 is further transmitted to the exchange, and in step 1916, the reservation signal is transmitted to the wireless base station 107 that is the reservation target. In this way, the wireless base station 107, which has received the wireless channel reservation request from the wireless terminal 102, confirms the channel usage status of the own station 107 in the control device of the wireless base station from the information table stored in the storage device, The information table is changed so that the wireless channel owned by 107 is reserved for the wireless terminal 102. The reservation fee will be described later,
The charging timer is started by this channel reservation (more specifically, step 2601 shown in FIG. 26). When the channel is secured, the route opposite to that at the time of the reservation request is traced, and steps 1918, 1919, and 1920 are performed in this order from radio base station 107-switching station 110-radio base station 1.
06-The wireless terminal 102 is transmitted in the order of the reservation completion notification 2002 in the format shown in FIG. The reservation completion notification 2002 includes a wireless terminal ID 2005, a reservation reference number 2008, and a reservation completion 2009.

By the way, securing a wireless channel is securing a kind of profit. Therefore, in order to prevent unnecessary reservations,
An appropriate management method would be to charge according to securing profits. By thus charging, unnecessary channel reservations can be reduced and effective use of wireless channels can be achieved. Specifically, in step 1921, the reservation charging command notification 2003 shown in FIG.
Send to 0. Here, the charging command in the reservation charging command notification 2003 includes information indicating charging start, charging stop, and the like.

When the reservation is completed in this manner, the user can call on the reserved wireless channel by moving to the service area 105 of the wireless base station 107 and making a call by relying on the displayed map. .

FIG. 21 is a sequence for reserving a peripheral wireless channel using the dedicated lines 108 and 204 (wired or wireless) between the wireless base stations shown in FIGS. Is shown. The steps until the radio channel reservation trigger is applied and the reservation request signal for the radio channel of the radio base station 107 is transmitted to the radio base station 106 in step 1914 are the same as in the case of FIG. Omit. In step 1901, the wireless base station 106 that has received the reservation request receives the reservation request via the leased line 108.
The reservation request signal is directly transmitted to the wireless base station 107. The radio base station 10 that has received the reservation request signal from the leased line 108
The step 7 secures a wireless channel in step 1917, and transmits a command signal to the exchange 110 so as to start reservation charging in step 1921. When the wireless channel is secured and the reservation is completed, in step 2102, the reservation completion notification is directly notified to the wireless base station 106 via the leased line, and step 1
At 920, the wireless terminal is notified of the reservation completion, and the reservation operation is completed.

FIG. 22 is a sequence diagram in the configuration of FIGS. 8, 15 and 16 in which map information exists in the radio base station. However, in the case of FIG. 16, it is premised that map information has been received from the road traffic information providing station in advance. In this case, map transmission and wireless channel usage status mapping processing is different from the case described with reference to FIG.

In step 1907, the wireless terminal requests the wireless base station to transmit map information. Then step 2
At 201, the wireless base station A 106 maps the current wireless channel usage status of its own station and the surrounding wireless channel usage status on the map information stored in the map information storage unit 801 shown in FIG. Subsequently, in step 1911, the map information is transmitted to the requested wireless terminal.

FIG. 23 shows a reservation sequence 2331 in a configuration in which the radio base station 106 shown in FIG. 2 and the peripheral radio base station 203 are controlled under different exchanges. The sequence of sending map information and the like are as described above, and the mapping is as described in FIG.

In this configuration, the switching center 110 notifies the switching center 206 of the reservation information via the line network in step 2303, the switching center 206 transfers the reservation information to the wireless base station 203 in step 2304, and step 1917. Then, the wireless base station 203 secures a wireless channel, and step 230
From 5 to 2308, the reservation completion notification is given to the wireless terminal. The reservation operation via the leased line 108 is shown in FIG.
Since it is as described for item 1, detailed description is omitted.

FIG. 24 shows a case where map information exists in a device higher than the exchange (FIGS. 13 and 14, etc.). FIG.
The difference from the sequence described in 9 is that the terminal side maps the wireless channels on the map. Specifically, in step 1909, the map information is transmitted from the exchange station 110 to the wireless base station 106. Next, step 240.
In step 1, the wireless base station 106 displays the use status of wireless channels of nearby wireless base stations together with this map information.
Send to In addition, as described above, the map information includes latitude and longitude information, and the wireless channel usage status includes position information according to latitude and longitude of wireless base stations in the vicinity. However, other than the latitude / longitude information, other position specifying information may be used as long as it can specify where on the map the wireless base station exists as a result. For example, a configuration example of a map 2501 is shown in FIG. 25. If the map information is managed in advance as image information composed of m × n dots, the position 2502 of the wireless base station on the map will be (k,
1) (However, if the service area is a circular cell having a radius r, then K, 1 is -r≤k≤m + r, -r≤1≤
n + r. ). In this way, if the relative position of the wireless base station is registered together with the map information in advance, the same effect as the absolute position method using latitude and longitude can be obtained.

In step 2402, the wireless terminal 106 maps the map information transmitted from the wireless base station in step 2401, the position of the wireless base station, and the usage status of the wireless channel. Incidentally, as shown in FIG. 4, the map information may be transferred to the portable computer 403, and the portable computer may perform a mapping process and display the map by itself.

Although the reservation sequence has been described above,
This reservation has the problems described above. The problem is that the present invention has a configuration in which the wireless channels of the peripheral wireless zones can be reserved in advance. Therefore, if this reservation is made possible without any restriction, there is a possibility that a useless reservation will occur unnecessarily. There is. As a result, the number of unused channels secured by reservation is increased, which causes a problem of traffic congestion. Therefore, the present invention has a configuration for forcibly canceling the reservation after a certain time has elapsed after the reservation in order to limit the useless reservation.
Further, the present invention provides a wireless channel reservation system capable of reducing unnecessary reservations by collecting a fixed fee even while a wireless channel is secured by reservation.

FIG. 26 shows a sequence for canceling a reservation based on the user's will. Wireless terminal 102
When a reservation completion notification arrives from the wireless base station 106, it means that the wireless channel is being reserved for the display device in step 2601 (for example, “reservation completed”, “reserved”, “RESERVED”,
For example, turning on a specific LED. ) Is displayed. Alternatively, instead of displaying it, the control device converts specific voice information stored in the storage device (such as the voice "reserved" meaning reserved) into voice and outputs the voice to inform the user. A configuration is also possible.

Next, in step 2602, when the reservation cancel trigger is issued by the user from the keypad or the touch panel, the control device 510 of the wireless terminal judges it, and in step 2603 the wireless terminal 102 makes a reservation with the wireless base station 106. A cancel signal for canceling is transmitted. In step 2604, the reservation cancellation notice is transmitted to the exchange 110, and in step 2605, the exchange 1
The reservation cancellation notification is transmitted from 10 to the wireless base station 107. The radio base station 10 that received the reservation cancellation notice
7 deletes the reservation from the wireless terminal 102 from the reservation database in the storage unit 712 of the wireless base station 107, the switching station 110 in step 2606, the switching station to the wireless base station 106 in step 2607, and the step 2608. The cancellation procedure completion notification is sent from the wireless base station 106 to the wireless terminal 102. On the other hand, at the same time as canceling the reservation, the wireless base station 107 issues a reservation charging stop command to the switching center in step 2609, and the switching center 110 receiving this command stops charging in step 2611. In addition, the release of the wireless channel secured by the reservation cancellation is performed in step 2610.

On the other hand, in the sequence shown in FIG. 27, the wireless terminal 102 transfers from the wireless base station A106 to the wireless base station B10.
Reservation cancellation when the user moves away from the service area of the radio base station A 106 to the service area of the radio base station C (which is a radio base station having the same configuration as 106, 107 etc.) after reserving No. 7 Will be described. Here, first, in step 2701, the wireless terminal issues a reservation cancellation notification to the wireless base station C. This reservation cancellation notification is issued at the time of reservation, or the ID of the wireless terminal, the ID of the wireless base station B that is the reservation destination,
The reservation reference number is shared by the wireless terminal and the wireless base station or exchange. Next, step 2702.
Forward the reservation cancellation notice to the exchange and proceed to step 27
In 03, the exchange searches the reservation database from the ID of the wireless base station B that is the reservation destination or the reservation reference number included in the reservation cancellation notification, and determines that the reservation cancellation notification should be transferred to the wireless base station B. Step 2605
Reservation cancellation operation in the wireless base station B such as FIG.
Since it is similar to 6, it is omitted. When the cancellation completion notification arrives at the exchange, it is transferred to the wireless base station C in step 2704, transferred to the wireless terminal in step 2705, and at the same time, the charging stop process is performed and the cancellation sequence ends.

Next, a description will be given of a configuration in which the reservation is forcibly canceled after a certain time has elapsed after the reservation in order to limit unnecessary reservations.

In FIG. 28, the wireless base station 107 performs step 1
After securing the channel in 917, the reservation time is measured in step 2801.
Starts a timer for a predetermined time from the current time. After that, if there is a call from the reservation person before the elapse of a certain period of time, the timer is canceled and the reservation charge is also stopped.
On the other hand, if no call is made within this fixed period of time, the control device 711 recognizes that it has timed out in step 2802,
The timeout information 2011 is sent to the wireless terminal 102 in the sequence of steps 2803, 2804, and 2805.
Will be notified and the reservation charge will also be stopped.

Further, the timeout is a kind of reservation cancellation, and the processing after the timeout is the deletion from the reservation database, the channel release, and the charging stop processing as described in FIG.

FIG. 29 is a sequence when the reservation time is measured at the exchange. When the reservation completion notification arrives at the exchange in step 1918, the control device inside the exchange starts a timer for a predetermined time from the current time. After that, if there is a call from the reservation person before the elapse of a certain time, the timer is released. On the other hand, if no call is made within this fixed time, the control device determines that the time-out has occurred in step 2902, and the following steps 2804 and 280 are performed.
In the sequence of 5, to the wireless terminal 102, step 29
At 03, the wireless base station 107 is notified of the timeout. In addition, the timeout is a kind of reservation cancellation, and the processing after the timeout is the deletion from the reservation database, the channel release, and the charging stop processing as described in FIG.

Finally, mapping of map information and wireless channels will be described. The radio base station 1604 that has received this map information cuts out only the necessary parts of the received map as shown in FIG.
003 and 3004 are mapped. Here, the "channel meter" is to graphically display the usage status of the wireless channel. Furthermore, this channel meter can notify the user of the possible range of the wireless connection service of each wireless base station by mapping the service areas 3005, 3006, and 3007.

Details of the mapping will be described below.

FIG. 30 shows an example of map information displayed on the wireless communication terminal. On the screen 3001 of the display device, in addition to the map, channel meters 3002, 3003, and 3004 are displayed in order to make it easy to visually understand the usage status of the wireless channels corresponding to the positions of the wireless base stations. In this example, the channel meter 3002 shows a situation where three channels are in use and only one channel is vacant. Further, in the channel meter 3003, all channels are closed. Further, the channel meter 3004 has three vacant channels. On the other hand, to clarify where on the map the service area of each wireless base station is, 3005, 3
The rough boundary area of the service area is displayed like 006 and 3007. By displaying the service area in this way, it becomes easier for the user of the terminal to move to the service area of the vacant radio base station, so that the concentration of traffic to a specific radio base station is dispersed. Occurs. In this case, in order to reduce the information amount of the map information to be notified, the map information should be notified intermittently or when there is a change in the status of the wireless channel or only the difference between the previous map information and the current map information. If so, the communication line is not wastefully occupied, and the transfer time can be significantly shortened. A communication format such as map information is shown in FIG. This communication format is basically the map information part 3104, such as 3101,
The wireless base station information unit 3105 is included, and more specifically, image data 3106, latitude / longitude information such as map size information, wireless base station ID information 3108, wireless base station installation position information 3109, and wireless channel usage status. 3110,
Although illustration is omitted, it includes wireless service area information such as a cell radius. Here, with respect to the information 3102 initially sent from the wireless base station to the wireless terminal, the difference data is sent for the data sent for the second time and thereafter, so that the information compression is performed and the transfer time is shortened. Also, the calculation of these differences is
This is performed by the control unit 510 in the radio base station.

Further, in FIG. 16, the mapping on the map may be performed by the wireless terminal 1602. In this case, the map information provided by the road traffic information station 1601 may be directly received by the wireless terminal 1602. Or once
Alternatively, the wireless terminal 1602 may receive the wireless base station 1501, receive the wireless base station 1501 through the wireless base station 1501, and send the wireless base station 1501 on a control channel. Therefore, after the map information is transmitted by any of the above-mentioned methods, only the use condition of the wireless channel of the peripheral wireless base station is transmitted from the wireless base station to the wireless terminal.

Specifically, the format of the map information is sufficient if simple latitude and longitude information of the map is added to the image information. Further, the latitude / longitude information can be calculated and the position where the channel meter is to be mapped can be obtained and mapped if only the latitude and longitude of the two points on the upper left and lower right of the map are known. These calculations are performed by the control unit 510 of the wireless terminal, the control unit 711 of the wireless base station, and the like. The latitude and longitude information of the map is
If the size of the map is fixed or one dot of the map information corresponds to how many times it corresponds, only the latitude and longitude information of one point on the map may be used. Also,
The position to which the channel meter should be mapped may be transmitted as latitude and longitude information of the wireless base station together with the ID number of the wireless base station and the usage status of the wireless channel.

32 to 38 show another example of the configuration of the channel meter. In FIG. 32, the number of vacant channels is indicated by a numeral. Conversely, only the used channel may be shown. Further, FIG. 33 shows a channel meter in which the service area is color-coded according to the congestion level. As a result, the user can grasp the usage status of the wireless channel based on the difference in color. In FIG. 34, service area 3
401, 3402, and 3403 are shown as a pie chart such as a busy 3405 and a vacant 3404.
With this configuration, an inexpensive terminal can be provided because a color or black and white multi-tone liquid crystal is not required.

FIG. 35 shows a channel meter which also displays reserved wireless channels. The reference numerals in the figure indicate an empty display 3502, a reserved display 3503, and a used display 3504, respectively. By showing the reserved wireless channel, the user can know the situation of the service area in more detail. For example, even if all channels are occupied, it can be determined that the probability of immediate use is high if there are no subscribers. On the other hand, if the channel is not full and there are more subscribers, it may be possible to take other contact means. In any case, it is easy to grasp the usage status of the wireless channel which was completely opaque in the past.
It is expected to bring great economic effects to both users and carriers.

FIG. 36 shows how many people are waiting for a free wireless channel due to a reservation when there is no free wireless channel. With this channel meter, not only when making a reservation for a wireless channel in the vicinity of the wireless channel reservation system of the present invention,
It is possible to deal with a conventional reservation for waiting for a radio base station 106 in the radio service area 104 where a user is located. This is a case where the wireless terminal 102 reserves the wireless channel of the wireless base station 106 from within the service area 104. Specifically, the wireless base station 106 notifies the wireless terminal of FIG. 5 of the usage status of the wireless channel, and the control unit 510 indicates that all the current wireless channels are closed and that two reservation users exist. Upon recognition, the display unit 512 issues a display command to display four in-use displays and two reservation waiting displays. Here, the display unit 512
May include a controller for image display,
In this case, the control unit 510 issues a display command to the controller, and then the controller displays the channel meter 3601 as shown in FIG. 36 on the display device of the display unit.

FIG. 37 shows another embodiment of the channel meter. Next to the channel meter 3701 of the present invention described so far, a dedicated reserved channel meter 3702 for displaying the number of people who are making reservations is provided. This division configuration is characterized in that the user can predict the future wireless channel usage status because the current wireless channel usage status and the reservation status can be visually distinguished at the same time.

FIG. 38 shows the structure of another channel meter. The channel meter 3801 is an analog meter that indicates the quantity by a needle, a needle 3802 indicating the number of channels in use, and a needle 380 indicating the number of reserved channels.
3, including needle 3804 indicating the number of free channels. Further, the channel meter displays the number of channels at the position indicated by the needle. By the way, when the present invention is configured so that reservations other than the current number of wireless channels cannot be made, only two needles, one indicating the number of channels in use and the other indicating the number of reserved channels, do not have to be displayed. May be In this case, the user can calculate the number of free channels by calculating (the number of free channels) = (the total number of channels) − ((the number of used channels) + (the number of reserved channels)).

This method can also be applied to the case where the wireless base station notifies the wireless terminal of the usage status of the channel, and the number of channels in use, the number of reserved channels, and the number of empty channels are not sent. In addition, if only two data are notified, the remaining one can be calculated and obtained by the control unit 510.

By the way, it is possible to construct a system in which the peripheral wireless channel reservation of the present invention and the conventional wireless channel reservation of the service area coexist, and it is possible to display them separately.

By displaying the channel meter in this way and further combining the touch panel 601 with the display device,
It is also possible to issue a reservation request to the radio base station by touching a channel meter having three vacant channels such as 04 or the service area 3007 corresponding to 3004. Alternatively, the corresponding wireless base station may be reserved by operating the keypad.

[0096]

According to the present invention, the wireless terminal receives the wireless channel usage status sent by the wireless base station and displays it as a channel meter, thereby visually showing the usage status of the wireless channel in the wireless zone to the user. There is an effect that you can grasp.

Further, according to the present invention, since the map information and the channel meter can be displayed on the wireless terminal, the position of the vacant wireless channel can be grasped, and there is an effect that the user can voluntarily act to disperse the traffic. .

Further, according to the present invention, it is possible to make a reliable call by reserving the wireless channel of the target wireless service area existing in the vicinity of the wireless service area existing before moving.

Further, according to the present invention, the location information control station or the exchange station has the map information, or the radio terminal side is connected to the CD-ROM reading device, and the CD-ROM storing the GPS map information is stored. Since it is possible to mount and display a map on the display device on the wireless terminal side, by providing a configuration that effectively utilizes the existing resources while maintaining the affinity with the existing telephone system, Moreover, there is an effect that the system of the present application can be introduced at low cost.

Further, according to the present invention, since only the portion updated at the time of transferring the map, that is, only the difference data from the immediately preceding information is transferred, there is an effect of shortening the transfer time of the map information.

Further, the present invention has a structure for forcibly canceling the reservation after a certain time has elapsed after the reservation, and has a structure for collecting a fixed reservation fee while the wireless channel is secured by the reservation. So you can limit unnecessary reservations,
This has the effect of promoting proper operation of the wireless reservation system of the present application.
