Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a mobile communication system. In the mobile communication system, a wireless base station (BS) is provided for each wireless area, and a wireless communication is performed with a mobile device (MT) in the wireless area. In this case, in addition to the conventional outgoing / incoming call service, further service to the mobile device is required.

[0002]

2. Description of the Related Art Conventionally, the current position of a mobile device is known by a high-frequency position registration area set by the convenience of the mobile communication carrier, and there is little meaning to perform incoming call control according to the position registration area. It was In addition, in order to identify the position of the mobile device, radio wave propagation delay and satellite (GPS: Gl
A method based on the Global Positioning System) has been considered, and is partially put into practical use.

Further, a method of cutting off radio waves has been put into practical use in order to make it impossible to receive a call to a mobile device in a private area such as a store.

[0004]

Each of the methods conventionally used for specifying the position of a mobile device has the following advantages and disadvantages. Expensive devices are required for the method of propagation delay of radio waves and the method using satellites. In the method shown in (1), the latitude and longitude information of the mobile device can be obtained, but since the incoming call control cannot be performed based on them, it is necessary to correlate them with the map information. Therefore, there is a problem that the processing load is large. In the method shown in (1), it is difficult to perform accurate incoming call control because the error is large. In addition, there is a problem that the method of blocking the radio wave makes it impossible to contact in an emergency.

The present invention has been made in view of the above problems, and a private area is set, and the private area installer easily and finely controls incoming calls to mobile devices located in the private area. It is an object of the present invention to provide a mobile communication system capable of performing.

[0006]

In order to solve the above-mentioned problems, the present invention has the following constitution. (A) In addition to the location registration area defined by the public network (hereinafter referred to as the public area), a private location registration area (hereinafter referred to as the private area) suitable for controlling incoming call is provided. (B) The installer of the private area registers the call origination / termination control method for the mobile station located in the area in the location register (LR). (C) The mobile device registers in the location register that it is in the private area. (D) The location register executes the incoming / outgoing call control registered in (b) when an outgoing / incoming call occurs while the mobile device is in the private area. (E) It is possible for the caller to select a desired call-incoming method from the call-incoming / outgoing control method defined by the private area setter, and in the case of an emergency, it is possible to normally make an incoming / outgoing call to the mobile device without performing the outgoing / incoming call control. To do.

(1) FIG. 1 is a block diagram of the principle of the present invention. In the figure, 1 is a location register (L) including an authentication database 1a and a position management database 1b.
R), 2 is a signaling network to which the location register 1 is connected, and 3 is a mobile switching center (MSC) that is connected to the signaling network 2.
Is. There are a plurality of mobile exchanges 3 and they are connected to each other. Reference numeral 4 is an exchange (SC) connected to the signaling network 2 and the mobile exchange 3, and 5 is a fixed telephone connected to the exchange 4.

Reference numeral 6 denotes a public radio base station (BS) connected to the mobile exchange 3, and a plurality of public radio base stations (BS) exist. Reference numeral 7 denotes a wireless area that the public wireless base station 6 is in charge of. Reference numeral 8 is a newly provided private base station (PBS), and there are a plurality of them. Reference numeral 9 is a mobile device (MT), and 10 is a private location registration area (private area) that the private wireless base station 8 is in charge of. Reference numeral 11 denotes a location registration area (public area) that the mobile exchange 3 is in charge of.

According to this structure, by providing the radio base station 8 for notifying the private location registration area (hereinafter referred to as private area) information, the private area is set in the public location registration area (hereinafter referred to as public area). It becomes possible to define.

(2) According to a second aspect of the present invention, the mobile device holds two pieces of position information, that is, position information notified from a public wireless base station and position information notified from a private wireless base station. The new location information received from the public wireless base station or the private wireless base station after the movement is different from at least one of the location information held by itself, the location registration is performed in the location register.

According to this structure, since the mobile device 9 holds the information of the private area 10 in addition to the public area 11, it can be detected that the mobile device 9 has moved to a different private area 10. Moreover, by registering the location when the mobile device 9 moves to a different public area 11 or private area 10, it becomes possible to register the public area 11 and the private area 10 in the location register 1.

(3) The invention according to claim 3 is characterized in that the private wireless base station sets an expiration date for position information notified by itself. With this configuration,
By providing an appropriate valid period for the private area information and invalidating the private area information that has passed the valid period, it becomes possible to prevent inappropriate call origination / termination control.

As an example, consider a case where a private area A moves to a private area C via an area (non-private area B) in which the private area is not defined.
In an area other than the private area (for example, the non-private area B) that is subject to outgoing / incoming call restrictions, it is necessary to cancel outgoing / incoming call control. As a method for realizing this, there is a method of registering the location of a mobile device that has moved to the non-private area as being in the non-private area.

However, this method has a drawback that the load on the location register becomes heavy because the location registration is performed every time the mobile device goes out of the private area.
According to the present invention, it is easy to enable outgoing / incoming calls in the non-private area B in the above example by providing an appropriate effective period (for example, 30 minutes in a coffee shop) in the private area information instead of this method. Becomes If the mobile station is located in the same private area even after the expiration date of the private area information, location registration is performed again using the same private area information notified from the private wireless base station.

(4) In the invention according to claim 4, the mobile station is the same or different private station during the period from the reception of the position information reported from a certain private radio base station to the expiration of the validity period. When the same position information is not received from the wireless base station for use, the mobile device deletes the position information registered in the location register.

According to this structure, it is possible to register the location of the mobile unit that has moved to the non-private area in the description relating to claim 3 in the non-private area. Here, the fact that the mobile device has moved outside the non-private area is detected by not receiving the same private area information while the validity period of the private area information has expired.

(5) The invention according to claim 5 is applied when an outgoing / incoming call occurs in a mobile station in which the location information notified from the private wireless base station is registered in a location register. The call control method can be registered in the location register through the location register management terminal.

With such a configuration, a private area operator who wants to establish a private area (for example, if a private area is provided in a movie theater, the operator of the movie theater corresponds to this), the private area operator is in the private area. It is possible to register the incoming / outgoing restriction for the mobile device to be registered in the location register.

In the present invention, the location register deletes the registration of the location information when the expiration date of the location information has passed after the mobile station registered the location information notified from the private wireless base station. It is characterized by

According to this structure, the location register can delete the registration of the position information and cancel the call origination / reception regulation related to the registration of the position information. Further, in the present invention, the location register is

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 2 is a diagram showing a functional configuration of the present invention. The same parts as those in FIG. 1 are designated by the same reference numerals. The figure shows the functional configurations of the mobile station (MT), location register (LR) and mobile switching center (MSC).

In the figure, 1 is a location register,
15 is data setting for the location register 1
This is an LR management terminal for updating. In the location register 1, 21 is an authentication / outgoing call control unit, 22 is a position management unit, 23 is a private area outgoing / incoming call control data unit, and 24 is an incoming call control unit.

From the authentication / outgoing call control unit 21 to the location management unit 2
Inquiry is made to the mobile station of the transmission source, and the location information of the mobile station is given from the location management section 22 to the authentication / outgoing call control section 21. Further, the location management unit 22 issues an incoming call control request to the incoming call control unit 24, and the incoming call control unit 2
4, the incoming call control response is returned to the location management unit 22. Data reference is performed between the authentication / outgoing call control unit 21 and the private area outgoing / incoming call control data unit 23, and data reference is performed between the private area outgoing / incoming call control data unit 23 and the incoming call control unit 24.

In the mobile exchange 3, 3a is a call processing unit. The call processing unit 3a inquires of the destination MT position and the MT count to the position management unit 22, and the position management unit 22 issues MT position information and MT count to the call processing unit 3a. Also, the call processing unit 3a
The authentication / outgoing call control unit 21 gives an authentication request and an outgoing call control response, and the authentication / outgoing call control unit 21 gives an authentication response and an outgoing call control request to the call processing unit 3a. Further, the call processing unit 3a gives an incoming call control response to the incoming call control unit 24, and the incoming call control unit 24 issues an incoming call control request to the call processing unit 3a.

Further, the public wireless base station 6 notifies the public area management unit 9a of the mobile unit 9 of the public area information, and the private wireless base station 8 transmits the private area information to the private area management unit 9b. Be informed. Public wireless base station 6
Sends / receives a request to / from the mobile exchange 3,
A position registration request / response is exchanged with the position management unit 22.

FIG. 3 is a flowchart showing a processing procedure relating to MT location registration. Hereinafter, the public radio base station is abbreviated as BS, the mobile station is abbreviated as MT, the location register is abbreviated as LR, the mobile exchange is abbreviated as MSC, and the private radio base station is abbreviated as PBS. (S1) Whether or not the public area has changed is checked based on the notification information from the BS.

No change → S5 No change → S2 (S2) Whether or not the MT private area mode is set (when the mode is ON, position registration is performed using the notification information from the PBS). ).

When mode = on → Go to S3 When mode = off → To end (S3) It is checked whether or not the private area is changed by the notification information from the PBS.

Change → S4 No change → End (S4) When the private area is changed, it is checked whether the broadcast information of the PBS is correct, that is, whether the base station is authenticated.

Correct → S5 Incorrect → End (S5) MT saves new area information. (S6) A location registration request message including public area and private area information is transmitted to the LR. (S7) The location registration response message is received from the LR. (S8) End With this configuration, it is possible for the mobile device 9 to detect that the mobile device 9 has moved to a different private area 10 by holding the information of the private area 10 in addition to the public area 11. . In addition, the public area 11 where the mobile device 9 is different
Alternatively, by registering the location when moving to the private area 10, the public area 11 and the private area 10 can be registered in the location register 1.

In the authentication procedure of step S4, only the PBS provided in the private area is authenticated. The authentication procedure includes a method for authenticating (verifying) the validity of the information notified from the PBS inside the MT, and
A method of performing some authentication procedure between the BS and MT is conceivable, but either method may be used as long as the legitimacy of the PBS is guaranteed. In this procedure, the base stations (BS) provided in the public area are not authenticated, but these base stations may be authenticated.

In step S2, the private area is notified only when the private area mode of MT is set to ON. However, when such an MT operation is allowed, even if an MT in which the private area mode is turned on is located in the private area, the MT count of the private area does not reflect the MT. The reason is that the LR cannot operate the MT counter because the private area information is not notified to the LR.

As a method for improving the accuracy of the MT counter, it is conceivable that the MT is notified of the private area information at the time of position registration regardless of the setting of the private area mode (the notified private area mode information is , LR). However, when an incoming call arrives at an MT in which the private area mode is turned on, for example, the caller should not be notified of the location information of the MT by an announcement or the like. Operation that does not notify the location information of the destination (for example, the destination MT
It is necessary to simply give an announcement that the incoming call cannot be received to the incoming call destination MT without notifying the present location information.

As a specific example, a case where a private area is provided in a movie theater A and at the same time, selection and setting are made so that incoming calls cannot be made to MTs located in the private area Think M in the movie theater A
When T comes in, location registration is performed for the LR. After that, when an incoming call is made to the MT, if the private area mode of the MT is ON, notification of the private area in which the called party is located is permitted.
The LR incoming call control unit 24 (see FIG. 2) controls the caller to give an announcement such as "The incoming call destination MT is in the movie theater A, but the current call cannot be received due to some reason."

FIG. 4 shows the procedure of MT at the time of position registration and FIG. 5 shows the procedure of LR in the same case as the processing procedure when the above control is performed. First, MT of FIG.
The processing procedure of will be described. In this process, the private area information is notified to the LR even when the private area mode is turned on. (S1) Check whether the public area has changed.

It has changed → Go to S4 No change → Go to S2 (S2) Check whether the private area has changed.

It has changed → Go to S3 No change → To the end (S3) The base station checks whether it has been authenticated.

Authenticated → S4 Not authenticated → End (S4) Save new area information. (S5) The MT makes a location registration request (public area, private area, private area mode) to the LR. (S6) The LR returns a location registration response (public area, private area, private area mode) to the MT. (S7) End Next, the processing procedure of the incoming call control unit 24 of the LR will be described. FIG. 5 shows the procedure in the case of considering the private area mode setting of MT. (S1) The location management unit 22 issues an incoming call control request. (S2) Upon receipt of this request, the LR refers to the private area outgoing / incoming call control data section 23. (S3) Next, the incoming call control unit 24 issues an incoming call control request to the MSC. Here, if the private area mode of the called party MT = ON, call control that does not notify the location of the visited area is selected / requested. (S4) The MSC sends the incoming call control response to the incoming call control unit 24.

(Example 1) Position Registration by Moving to Private Area A position registration performed by moving the MT to a private area will be described. FIG. 12 is a sequence diagram showing location registration by moving to a private area. In the figure, MT1
Shows the sequence between the and PBS and LR. The initial state of the MT1 location management data not located in any of the private areas and the LR location management data relating to the MT1 is as follows.

MT1: public area = LA1, private area = undefined LR: public area LA1, private area = undefined (the above is the same as MT1), MT number in area = 0, where MT1 is a private area (identification number A private area identified by PLA 1. When moving to a movie theater, for example, a radio base station installed in the area (for example, the entrance of a movie screening hall) and periodically transmitting a radio signal based on a technology such as Bluetooth. From (PBS), notification information including a private area number (PLA number) and a relative effective period of the private area number (LT. For example, a movie showing time is set so that an incoming call is not allowed during the movie showing) To receive.

Then, the in-zone private area of the position management data of MT1 is updated to PLA1. Also, MT1 calculates an absolute valid period (ALT) at which the valid period of the private area number expires based on the notified LT, and holds these. Broadcast information (PLA =
PLA1, LT = 3600s) is transmitted.

Prior to performing these updating processes, the MT 1 authenticates (preferably) whether or not the broadcast information of the PBS is correct by some authentication means. In this way, by performing the authentication procedure, it is possible to prevent a malicious person from registering the false private area information in the mobile device using the false private wireless base station.

Thereafter, MT1 sends a location registration request message to the LR. In this message, MT = MT
1, LA = LA1, PLA = PLA1, LT = 3600
s is included. Here, L is added to the location registration request message.
Although T is set, A calculated by MT1
LT may be set.

The LR that has received the message is also MT1
Similarly, the location management data regarding MT1 is updated.
In addition, when counting the number of MTs existing in the private area, 1 is added to the count. After performing these processes, the LR sends a location registration response message indicating the completion of PLA1 update to MT1. After that, time AL
Even when T (7:00 pm) is reached, when the location registration request message is not transmitted from MT1, the LR deletes the location management data regarding the private area PLA1 and decrements the in-zone count by one.

Further, in this way, it becomes possible for the location register (LR) to delete the registration of the position information concerned and to cancel the call origination / reception regulation related to the registration of the position information concerned.

As described above, in order to prevent the private area information in the LR from being erased, the MT1 is set to the time AL.
By the time T is reached, the location registration request message is transmitted to the LR again by the same procedure as described above. If the LR side does not delete the private area information based on the valid period, MT1 requests deletion of the private area information (PL
Send a location registration request message (assuming A = NULL). (Embodiment 2) Incoming Call Control in Private Area-Part 1 Incoming call control for MTs in the private area will be described. FIG. 13 is a sequence diagram showing a first example of incoming call control in the private area. In the figure, the sequence among the fixed telephone (FT1), the calling MSC (O-MSC), the LR, and the voice mail device (V-MAIL) is shown. The initial state of the location management data of MT1 located in the private area (PLA1) and the location management data of LR related to the MT1 is as follows.

MT1: public area = LA1, facility area = PLA1 LR: public area = LA1, facility area = PLA1 (M
(Similar to T1) The installer of PLA1 connects to the voice mail device (V-MAIL) or transfers to (V-MAIL) when a mobile device (MT) located in the facility area receives an incoming call. XXX
-XXXX), the caller is desired to be selected, and the fact is registered in the private area outgoing / incoming call control data section 23.

In this state, a fixed telephone FT1 to MT
The case in which an incoming call occurs at No. 1 will be described below. M
The call setup request message for T1 is issued by the MSC (OM
When the SC) receives it, the O-MSC sends an MT location inquiry message to the LR. Where LR is
When MT1 is in the private area PLA1 and recognizes that the call reception control method desired by the installer of the private area is registered, the caller sends an announcement prompting the caller to select the call reception control method, and the call is transmitted. The O-MSC is requested to transmit an announcement transmission and information collection request message that the selection information from the person is to be obtained. In this way, the caller can select the desired mode.

After transmitting the requested announcement, the O-MSC receives the incoming call control selection signal from FT1. F
When T1 requests an incoming call to the voice mail device V-MAIL, they are notified to the LR. The LR is the information (RN) needed to route the call to the voice mail device.
The MT position information message in which the is set is transmitted to the O-MSC. Then, the call is connected from the O-MSC to the voice mail device, and the FT1 registers the voice mail.

When the incoming call is not accepted and the call is disconnected after the announcement is transmitted, the announcement transmission request message is transmitted instead of the announcement transmission and information collection request message, and the call is disconnected after the announcement is transmitted. It In this way, as an incoming call control method,
It is possible to provide a mode for disconnecting the call after connecting to the announcement device and notifying the user that the area is restricted.

Also, the voice mail is MT as a character mail.
In the case of sending to 1, the call is connected to a server having a voice-character conversion function instead of the voice mail device. The character mail generated by the server is transmitted to MT1 by the existing method. By doing so, it becomes possible to convert the voice of the caller into character information and receive the call. (Third Embodiment) Incoming Call Control in Private Area—Part 2 Incoming call control for MTs in the private area will be described. FIG. 14 is a sequence diagram showing a second example of incoming call control in the private area. In the figure, a fixed telephone (FT1), a calling MSC (O-MSC), and a T-MSC
And the sequence between MT1. Where T-
The MSC is an MSC that controls the area in which the MT1 is located. It is assumed that the initial state of the LR location management data regarding MT1 existing in the private area (PLA1) is the same as that in the second embodiment, and the incoming call control data regarding the private area installer is the same as that in the second embodiment. Is registered.

In this situation, when an incoming call is generated from FT1 to MT1 located in the private area (PLA1), LR uses the same procedure as in the second embodiment.
Prompts the user to input the incoming call control selection signal. Where FT
No. 1 does not perform the incoming call control desired by the facility area installer because it is urgent to communicate with MT1, and immediately inputs the selection signal "0" requesting an incoming call to MT1. The information is LR
Is notified, the LR responds to the O-MSC with a routing number (RN) for performing routing to the MSC (T-MSC) that controls the area in which MT1 is located. After this, the O-MSC sends a call setup request message to the T-MSC, and the incoming call to MT1 is made.

In this way, the mobile unit (M
It is possible to make an incoming call at T1). In this embodiment, the caller's convenience (incoming call control rejection) is prioritized over the private area installer's incoming call control, but the private area installer's wish (incoming call rejection) is prioritized. May be. (Embodiment 4) Outgoing call control in a private area Next, outgoing call control for an MT in the private area will be described. FIG. 15 is a sequence diagram showing outgoing call control in the private area. Here, MT1 and O
-Shows the sequence between MSC, LR and FT2. Further, as a precondition, the initial state of the LR location management data regarding the MT1 existing in the private area (PLA1) is the same as that in the second embodiment, and the transmission control regarding the private area installer is as follows: Yes. However, outgoing calls are permitted for emergency calls. , Which is registered in the private area outgoing / incoming call control data section 23.

When MT1 makes a call to the fixed terminal (FT2), first, an authentication request message is sent to LR in order to authenticate MT1. Here, when the authentication of MT1 is successful, the fact is replied to the O-MSC.
At this time, an outgoing call control flag indicating that outgoing call control is continuously performed is simultaneously transmitted. O- that received the flag
The MSC suspends the call processing for the FT2 designated by the MT1 as the destination, and waits for the outgoing call control continuously performed from the LR.

The LR is prepared by the same procedure as in the second embodiment.
The MT1 is prompted to input the transmission control selection signal. Here, MT1 inputs a selection signal "1" for permitting the call origination control desired by the private area installer, unless an emergency is required to communicate with FT2. When the information is notified to the LR, the call is disconnected.

If the MT1 is in urgent need of contacting the FT2, it immediately inputs the selection signal "0" requesting an incoming call to the MT1. When the information is notified to the LR, L
R permits the O-MSC to connect to FT2. Then,
The O-MSC resumes the call processing to FT2 which has been suspended. (Example 5) Counting the number of MTs existing in a private area A procedure for counting the number of MTs existing in a private area and notifying the count when a request is made will be described. FIG. 16 is a sequence diagram showing a procedure for counting the number of MTs existing in the private area. MT1 and O-MSC
And the sequence between LR.

MT1 transmits an MT count request message in which a service special number and information (PLA1) indicating a specific facility area are set to the O-MSC. When the O-MSC recognizes that MT1 requests the MT count information by the service special number, the O-MSC inquires the LR about the MT count information. LR uses PLA1 as a key
Retrieving T count information, O-MS
Respond to C. The O-MSC that acquired the count information,
M in the private area designated by the announcement
The MT number is notified to T1.

In this way, by counting the number of mobile stations in which certain specific private area information is registered, it is possible to estimate the number of persons existing in the private area.
