Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a mobile communication system, and more particularly to a mobile communication system in which a base station device and a plurality of mobile station devices are connected under a cellular system.

[0002]

2. Description of the Related Art FIG. 13 is a diagram for explaining a conventional technique.
The figure shows a state in which public networks (fixed network and mobile network) are deployed in the area of area code "044" (Kawasaki) and "045" (Yokohama). In the figure, TEL is a fixed telephone, EO is a switching center (terminal station) that accommodates the fixed telephone, 100 is a public network (including a mobile network), BS is a base station of the mobile network, and MS is a mobile station (portable terminal). is there.

In the figure, when the user a of the fixed telephone TEL1 makes a call to the doctor's office 200 who knows that he is in the same city (area code), the dialing of the area code "045" can be omitted. That is, the user a simply calls “222-
Simply dialing "3333" will receive the call to the telephone TEL2 of the clinic 200.

On the other hand, in recent years, the spread of mobile terminals has been remarkable, but since the mobile terminal MS moves in the mobile network, the area code is uniformly dialed regardless of the local / international telephone call. You need to make a call. That is, the mobile terminal MS1
The user b must call the number "045-222-3333" even when calling the clinic 200 in the same city.

By the way, as described above, it is good if the user b knows the area code "045" of the called party (the clinic 200) in advance, but there are many cases where the user does not actually know the area code. In particular, when the call destination is in the vicinity of the boundary area of the area code, such as the clinic 200, it is even rarer to know the area code. There is also a way to find out the telephone number from a billboard or leaflet on the street corner, but due to the long practice of fixed networks for making local calls without the area code, telephone numbers such as billboards and leaflets are still used today. The area code is usually not added to the number.
Therefore, conventionally, this has reduced the convenience of the mobile terminal.

Regarding this point, conventionally, the base station map in the mobile terminal device is searched by the base station number transmitted by the nearest base station, and the area code of the area in which the base station is located is stored in the RAM. At the same time, if the first dial number is other than "0" (that is, it is necessary to add the station number) when calling the station, the area code stored in the RAM is added to the call. A portable terminal is known (Japanese Patent Laid-Open No. 10-11737).
7).

Alternatively, if the area code is required when making a call to the local station, the area name corresponding to the area code received from the nearest base station is read out and displayed on the screen, and the user There is known a mobile terminal that calls by adding the area code of the confirmed area name (Japanese Patent Laid-Open No. 2000-261536).

Therefore, using these prior art techniques,
If the user b simply dials “222-3333”, the area code “045” of the area in which the base station BS1 is located is automatically added, so that the clinic 20
The incoming call can be made to the telephone TEL2 of 0.

[0009]

However, as described above, the base station BS1 has the area code "04" in its own area.
5 "is added to the wireless service area SE
1, the station number "045" where the base station BS1 is installed and the station number "0" where the clinic 200 is located
45 ”is good, but as in the wireless service area SE2, the station number“ 044 ”where the base station BS2 is installed does not match the station number“ 045 ”where the clinic 200 is located. There is a possibility that the recipient is wrong. That is, the user c in this case simply calls “2
22-3333 ", the mobile station MS2 in this case receives the area code" 04 "from the nearest base station BS2.
"044-222-3333" to be informed of "4"
And the call cannot be received at the clinic 200. Moreover, the user c has the correct area code "045" of TEL2.
If you do not know, you cannot call to TEL2 after all.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a mobile communication system capable of adding a correct area code even in a boundary area of the area code. .

[0011]

The above-mentioned problem is solved, for example, by referring to FIG.
It is solved by the configuration of. That is, the mobile communication system of the present invention (1) is a mobile communication system in which a base station device and a plurality of mobile station devices are connected under a cellular system, and a plurality of cities included in a radio service area SE2 of the own station. A base station device BS2 that mounts information of the area code "044,045" on the downlink control channel of the own station and broadcasts it, and a mobile station apparatus MS2 that sends the area code with the area code added for outgoing calls. And one or more base station devices BS in the vicinity
The information of a plurality of types of area code "044,045" received from No. 2 is displayed on the screen, and the destination code "222-3333" on which the manually selected area code "045" is dialed. To be sent by adding
And with.

According to the present invention (1), the user c of the mobile station MS2 has a clinic 200 which is located in the border area of the area code.
By selecting any of the area code "044,045" notified from the nearest base station BS2, the telephone TEL2 of the clinic 200 can be called without knowing the area code.

The present invention (2) is the same as the above invention (1), in which the base station device BS2 has geographical information that the area of the area code is occupied by the area of the area code within the wireless service area of the own station. Is added for notification.

For example, the wireless service area SE of this example
Since 2 is divided into east and west, the base station BS2 in this case, together with the information of the area code “044, 045”, is displayed geographically in the display frame as shown in the inset diagram (a). Information (area allocation information) is added and notified. In this case, the user c turns the head of the mobile station MS2 to the north (N pole) so that the left side has the area code "045" (Yokohama city) and the right side has the area code "044" (Kawasaki city). Can be easily recognized.

The present invention (3) is based on the above-mentioned present invention (2). For example, as shown in FIG. 2, the mobile station device MS1 receives each area code "044, 045" received from a plurality of base station devices BS2, BS4. , "044", the ratio of the area code area occupied in the wireless service area of each base station device is combined for each area code number and displayed on the screen.

The mobile station MS1 of FIG. 2 is the nearest (perch).
Area code "044,045" from the base station BS2
As a result, the basic area of the area code "044" is 10 points x 0.5 = 5 points, and the area code of "045" is the basic 10 points x 0.5 = 5 points.
Get points. Also, this mobile station MS1 is located at the second
As a result of being notified of one area code “044” from the base station BS4 of, the basic 10 points × 1 = 10 points are further added to the area code “044”. As a result, in this case, the weighting for each area code area where the mobile station MS1 will be located (located) is 15 points, which is 5 points + 10 points for the area code "044" (Kawasaki City), or For area code "045" (Yokohama City), you will get 5 points in total.

As a result, the mobile station MS1 is, for example, as shown in FIG.
As shown in (a), the area code "044" (Kawasaki City) is displayed with a high priority "1" on the screen, and the area code "045" (Yokohama City) is low priority. It is displayed on the screen with "2" added. This display well represents the geographical situation where the mobile station MS1 in FIG. 2 is likely to be located (located) (that is, the situation where the mobile station MS1 is likely to be on the side of Kawasaki City) and the user. Gives useful information on the area code selection by.

The voice signal (RD) from the base station 30 is output to the speaker 19 via the receiving unit 13, the synchronization control unit 16, the codec 17, and the baseband processing unit 18, and the voice signal (TD) from the microphone 20. Is transmitted to the base station 30 via the baseband processing unit 18, the codec 17, the synchronization control unit 16, and the transmission unit 14. On the other hand, the control signal (CD) for call processing and the like is processed by the CPU 21. The operation of the area code addition function according to the embodiment will be described below.

FIG. 6 is a flow chart of the area code receiving process according to the embodiment, and the main process is shown in FIG. 6 (A). The base station 30 carries the area code information in the broadcast information of the downlink control channel and transmits it, and the mobile station 10 receives this broadcast information and inputs it to this processing.

In step S11, area code information is acquired from the broadcast information. In step S12, it is determined whether or not the acquired area code information is acquired from the already received base station. If it is obtained from the received base station, the area code information is stored in the memory 22 in step S13.
Overwrite and save in the storage area of the area code information corresponding to the relevant base station. If it is not acquired from the already received base station, the area code information is stored in a new storage area of the memory 22 in step S14. In any of the above cases, the monitoring timer i (i corresponds to each base station) is started in step S15, and this processing is exited. In this way, the area code information from each base station around the mobile station 10 is received and extracted at any time and stored in the memory 22.

FIG. 6B shows the timer interruption process. When any one of the monitoring timers i times out, it is considered that the mobile station 10 is not already in the radio service area of the base station. , Input interrupt to this process. In step S21, the monitoring timer i that has timed out
The area code information corresponding to is deleted from the memory 22 and the process is exited. In this manner, the memory 22 always receives and stores only the area code information from each valid peripheral base station.

FIG. 7 is a flowchart of the calling process according to the embodiment, and FIG. 7A shows a case where the area code is added after the user's calling (dial) operation. In step S31, the user performs a dialing operation. In step S32, it is determined whether the area code addition process is necessary. Here, when the user first dials "0" (the area code such as 03/044) or "1" (the special number such as 110/119), the processing of adding the area code is unnecessary. . When the user first dials a value other than "0" or "1", it is considered that the user has input from the local number, and therefore the area code addition process is necessary.

When it is necessary to add the area code, the area code information stored in the memory 22 is first read in step S33. At this time, if the area code information from a plurality of base stations is stored in the memory 22, step S34
The area code (area) is weighted by. The details of the weighting calculation will be described later. In step S35, the mobile station 10
The area code of the area where will be located is displayed on the display unit 24. In step S36, the user selects the desired area code using the keyboard 25, if necessary.

If it is not necessary to add the area code in the determination in step S32, steps S33 to S36 are performed.
Skip the process of. Then, in step S37, the call is transmitted.

FIG. 7B shows a case where the user performs a dialing operation after selecting the area code. In this case, the area code selection operation similar to steps S33 to S36 is performed first. In the following step S31, the local number is dialed, and in step S37 the call is sent.

FIG. 8 is an image diagram (1) of an area code display example according to the embodiment, in which weighting calculation is not performed (that is,
It shows a relatively simple case (the process of step S34 in FIG. 7 is omitted). FIG. 8A shows a display example of the area code in the mobile station MS1 of FIG. This mobile station MS1 has two area code "0" from the nearest base station BS2.
As a result of being notified of "44,045", these area codes "044" and "045" are displayed, and preferably, information of each area name "Yokohama City". "Kawasaki City"
Is added and displayed. Also, this mobile station MS1 has a second base station BS4 in the periphery having a somewhat lower reception level RSSI.
Although one area code "044" is notified from this area code, since this area code "044" overlaps with the above, FIG. 8 (a)
There is no change in the display mode.

FIG. 8B shows a display example of the area code in the mobile station MS2 of FIG. This mobile station MS2 has one area code "0" from a single nearest (perch) base station BS3.
As a result of being notified of only "45", the area code "045" is displayed on the screen of the mobile station MS2, and preferably the area name "Yokohama" is added and displayed.

FIG. 8C shows a display example of the area code in the mobile station MS3 of FIG. This mobile station MS3 has one area code "0" from the nearest (perch) base station BS1.
45 ", one area code" 045 "from the second surrounding base station BS3, and 2 from the third surrounding base station BS2.
As a result of receiving one area code "044, 045", the area names "044" and "045" are displayed with the corresponding area names "Kawasaki City" and "Yokohama City" added.

In the other embodiment of FIG. 8, the mobile station MS can be configured to acquire only the station number information from a single nearest (perch) base station BS and display it on the screen. As shown in FIG. 4 (B), the base station BS in this case uses the geographical information (that is, within the wireless service area) that the area number area occupies in its own wireless service area, as shown in FIG. 4B. The direction and area ratio of each station number area occupying the area are added for notification, and the mobile station MS can display the area code by reflecting this geographical information.

For example, the mobile station MS1 shown in FIG.
If it is connected (standby reception) to the wireless service area SE2, it is divided into east and west.
BS2 in this case transmits the area information P7 of FIG. 4 (B), and the MS1 receiving this transmits the area information P7.
“044” will be displayed in the mode of FIG.
In this case, the user moves the head of the mobile terminal 10 to the north (N pole).
It can be easily recognized that the left side is the area with the area code "045" (Yokohama city) and the right side is the area with the area code "044" (Kawasaki city). If necessary, a compass may be embedded in the mobile terminal 10.

FIG. 9 is an image diagram (2) of an area code display example according to the embodiment, in which the weighting calculation of step S34 of FIG. 7 is performed and the obtained priority code is attached to each area code area. The case where it is displayed is shown. An example weighting operation is described below.

FIG. 9A shows a display example of the area code in the mobile station MS1 of FIG. In this case, the mobile station MS1 receives two area code "0" from the nearest base station BS2.
As a result of being notified of "44,045", the area code "044"
As for the basic 10 points x 0.5 = 5 points,
Also, for the area code "045", the basic 10 points x 0.5 = 5 points are obtained. Also, this mobile station MS1
Also has one area code "0" from the surrounding second base station BS4.
As a result of being notified of “44”, basic 10 points × 1 = 10 points are further added for the area code “044”.

As a result, in this case, the weighting for each area code area where the mobile station MS1 will be located (located) is 5 points + 10 points in total for the area code "044" (Kawasaki City), totaling 15 points. For points and area code "045" (Yokohama City), you will get a total of 5 points. As a result, the mobile station MS1 has the area code "04".
"4" (Kawasaki City) is displayed on screen 24 with a high priority of "1", and area code "045" (Yokohama City)
Is displayed on the screen 24 with a low priority “2”. This display well represents the geographical situation where the mobile station MS1 in FIG. 2 is located (located) (that is, the situation where the mobile station MS1 is likely to be on the side of Kawasaki City).

Information "1" on the priority order of each area,
The number of points (pt) may be displayed together with "2" and the like.
Further, the percentage of the area occupied by each station number area may be obtained from the ratio of each point number and displayed on the screen. Alternatively, the display frame of each station number area may be displayed in a size corresponding to each percentage.

FIG. 9B shows a display example of the area code in the mobile station MS2 of FIG. This mobile station MS2 has one area code "0" from a single nearest (perch) base station BS3.
As a result of being notified of only "45", the area code = "045" (Yokohama city), priority = 1, the number of points = 10 points, the area code "045" in the wireless service area SE3 is displayed on the screen of the mobile station MS2. The area ratio = 100% is displayed.

FIG. 9C shows a display example of the area code in the mobile station MS3 of FIG. This mobile station MS3 is one area code "045" from the nearest (perch) base station BS1.
As a result, the basic 10 points × 1 = 10 points are first obtained for the area code “045”. Also,
One area code "04" from the surrounding second base station BS3
As a result of being notified of “5”, basic 10 points × 1 = 10 points are obtained in the same manner as above for the area code “045”. Furthermore, from the surrounding third base station BS2, 2
As a result of being notified of one area code "044,045", the basic area code "044" is 10 points x 0.
5 = 5 points, basic 10 points × 0.5 = 5 points are obtained for the area code “045”.

As a result, in this case, the weighting of each area code area where the mobile station MS3 will be located (located) is:
5 points in total for area code "044" (Kawasaki City) and 10 points for area code "045" (Yokohama City)
You will get a total of 25 points, +10 +5 points. As a result, the mobile station MS3 displays the area code "045" (Yokohama City) with a high priority "1" on the screen 24 and displays the area code "044" (Kawasaki City) low. It is displayed on the screen 24 with the priority “2”. Expressing this as a percentage, the probability that the mobile station MS3 will originate from the area code "045" (Yokohama City) is 8
4%, and the probability of making a call from the area code "044" (Kawasaki City) is 16%. Such an indication indicates that the geographical situation in which the mobile station MS3 in FIG. 2 is located (ie,
There is a high probability that mobile station MS3 will be located in Yokohama City.)
Is well represented. The user of the mobile station MS3 selects an appropriate area code by using this display information as a guide.

In the example of FIG. 1, when the user c of the mobile station MS2 wants to call the clinic 200 in front of him, the probability that the user c is in the area of the area code "044" is 50. %, And the probability of being in the area with area code "045" is 5
It becomes 0%, and even if the user c fails to receive the call to the clinic 200 in the first selection “044”, the second selection “0” is made.
With “45”, the call can be reliably received at the clinic 200. In addition, at the time of this call, if the user c knows that he is on the side of Yokohama-shi, the area code "045" is maintained without hesitation from the beginning.
Can be selected and the call can be received at the clinic 200.

FIG. 10 is an image diagram (3) of an area code display example according to the embodiment. In addition to the case of FIG. 9 described above, FIG. 4 (B) in which the mobile station MS is informed from the surrounding base station BS.
In consideration of the area information P0 to P8 shown in step S3, step S3

FIG. 10 (a) shows a display example of the area code in the mobile station MS1 of FIG. In this case, the mobile station MS1 is notified of the area information P7 together with the two area code "044,045" from the nearest base station BS2.
Also, the area information P0 is notified from the second base station BS4 in the vicinity together with one area code "044". At this time, the fact that the base station BS2 is on the north side of BS4 means that the mobile station M
Since it can be known in S1 (for example, it is notified by additional information), the mobile station MS1 combines the area information P7 from BS2 on the upper side and the area information P0 from BS4 on the lower side, and displays them on the screen 24. At this time, if the user points his / her head of the mobile terminal MS1 to the north side, the area code display of this screen 24 is more concrete than the situation (area code map) around the mobile station MS1 in FIG. It is an accurate representation.

FIG. 10B shows a display example of the area code in the mobile station MS2 of FIG. This mobile station MS2 is notified of the area information P0 together with one area code "045" only from the single nearest (perch) base station BS3.
