Abstract

PROBLEM TO BE SOLVED: To realize the 'sharing characteristic' that a plurality of portable telephones use the one set of external equipment while securing communicative 'secrecy' in a radio communication system connected between the portable telephone and the external equipment to perform communication through the portable telephone, such as a hand-free device, by local radio communication. SOLUTION: A registration request part 4 is mounted in a portable telephone 0 side, and an authentication information registration part 23 is mounted in an external equipment 20 side, respectively. Before establishing communication, based on the registration request from the registration request part 4, the portable telephone is registered into the external equipment 20 side by the authentication information registration part 23. Then, when actually establishing the communication, the external equipment 20 permits connection only to the previously registered portable telephone 0 by the authentication part 24. Thereby, because only the portable telephone registered previously to the external equipment side is possible for the communication with the external equipment, the communicative 'secrecy' is secured and the 'sharing characteristic' that a plurality of portable telephones use the one set of the external equipment is realizable by registering the plurality of portable telephones previously.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless communication system in which a portable telephone is connected by local wireless communication to an external device, such as a hands-free device, which communicates via the portable telephone. The present invention relates to a mobile phone, an external device, and a wireless communication method.

[0002]

2. Description of the Related Art In recent years, portable telephones including PHS have rapidly spread, and portable computers and other so-called mobile devices have become smaller and have higher performance. The so-called mobile communication for performing communication has been actively performed. Also, to prevent danger from using a mobile phone while driving a car,
Use of a mobile phone while driving a car is only permitted when using a hands-free device. in this way,
Nowadays, it has become common to connect and use various external devices such as hands-free devices and mobile devices with mobile phones. Instead of connecting external devices and mobile phones with cables, both devices are connected wirelessly. A new need to connect has emerged. It has been proposed to use a new technology such as Bluetooth for wireless connection between a mobile phone and an external device. This Bluetooth
Was just proposed for the standardization of short-range wireless connection targeting mobile communications, etc., and 2.45
Using the GHz band, it covers a connection distance of about 10 meters, and automatically detects devices in the communication area.
It is a local wireless communication standard that can automate network configuration by allocating addresses.

However, when a portable telephone is connected to an external device by wireless communication such as Bluetooth, there is a problem of crosstalk when, for example, a plurality of portable telephones exist within a wireless communication range of one external device.
For example, there is a concern that a call may be transmitted from one's hands-free device via another person's mobile phone, or an incoming call to one's own mobile phone may be received by another person's hands-free device. Therefore, a technique for solving such a problem of crosstalk has been proposed in, for example, Japanese Patent Application Laid-Open No. H11-98578. The hands-free telephone device proposed in the above publication is configured to perform wireless communication between the mobile phone and the hands-free device, and establishes wireless communication only when the IDs on the transmitting side and the receiving side match. It is to do.

[0004]

However, in the hands-free telephone device proposed in the above-mentioned publication, the wireless communication device on the portable telephone side and the wireless communication device on the hands-free device side have a one-to-one correspondence. Therefore, although “confidentiality” of communication can be ensured, realization of “shareability” in which one external device is used by a plurality of mobile phones is not considered. For example, when a car is equipped with a hands-free device, it is desirable to realize “sharing” that allows connection with a plurality of mobile phones, in consideration of use by a plurality of drivers. In addition, external equipment has multiple functions (for example, hands-free function and Internet terminal function)
In the case of having a mobile phone, a plurality of users may use different functions using their respective mobile phones, but this is also possible only when the above-mentioned “sharing” is realized. The present invention has been made in view of the above circumstances, and an object of the present invention is to realize both “confidentiality” and “shareability” in wireless communication between a mobile phone and an external device.

[0005]

To achieve the above object, a first aspect of the present invention comprises a mobile phone and a predetermined external device that performs communication via the mobile phone. In a wireless communication system in which communication with an external device is performed wirelessly by a local wireless communication device mounted therein, the external device registers a mobile phone identifier unique to the mobile phone based on a predetermined registration request. Before establishing communication with the authentication information registering means and the mobile phone, the mobile phone identifier of the mobile phone is compared with each mobile phone identifier registered in the authentication information registration means. And an authentication means for establishing communication only with the wireless communication system. As a result, only the mobile phone registered in advance on the external device side can communicate with the external device, so that "confidentiality" of communication is ensured, and a plurality of mobile phones are registered in advance. Accordingly, "sharing" such that one external device is used by a plurality of mobile phones can be realized. Here, as the predetermined registration request, for example, the user can directly input a registration request to the external device by operating a button of the external device. A registration request means for transmitting a registration request by transmitting its own mobile phone identifier, and making a registration request wirelessly from a mobile phone using the registration request means. Becomes possible.

Further, the authentication information storage means stores, based on a predetermined registration request, a service identifier assigned to a plurality of services available in the external device in association with a mobile phone identifier unique to the mobile phone. One or more of these are registered, and the authentication means, prior to the establishment of communication with the mobile phone, the mobile phone identifier of the mobile phone and a service identifier of a service to be used by the communication, and the authentication The mobile phone identifier and the service identifier registered in the information registration means are compared with each other,
If the communication for the service is established only when they coincide with each other, the service content can be limited for each mobile phone and registered. At this time, when the registration request is made wirelessly from the mobile phone using the registration request means as described above, the registration request means transmits the own mobile phone identifier and the service to the external device. And the identifier. Further, as described above, when a registration request is made wirelessly from a mobile phone by using the registration request means, the registration request means of the mobile phone comprises:
An external device identifier unique to the external device to be registered is transmitted together with the mobile phone identifier, and the authentication information storage means of the external device stores the external device identifier received from the registration request means as its own external device identifier. It is preferable that the registration is performed based on the registration request from the registration request unit only when the ID matches. This makes it possible to restrict registration from an unspecified person, for example, by using a non-public information such as a password as the external device identifier.

Further, if the wireless communication between the portable telephone and the external device is always established based on a connection request from the portable telephone to the external device,
The mobile phone does not consume power for waiting for a connection request from an external device, and can effectively use a limited battery capacity. Further, the external device is provided with standby processing means for detecting that the user is in a usable state and shifting the external device to a standby state for a connection request from the mobile phone. Can be minimized. Here, as the standby processing means, for example, detection of vibration of the external device, detection of the approach of the user to the external device, or detection of a person riding when the external device is an on-vehicle device (engine (Starting, vibration, etc.) to determine that the user is ready for use.

[0008] The second and third inventions are external devices and a portable telephone which constitute the above-mentioned wireless communication system, respectively. According to a fourth aspect of the present invention, there is provided a wireless communication method for performing wireless communication using a local wireless communication device between a mobile phone and a predetermined external device that performs communication via the mobile phone. An authentication information registering step of registering a mobile phone identifier unique to the mobile phone; and, prior to establishing communication with the mobile phone, the mobile phone identifier of the mobile phone and each mobile phone identifier registered in the authentication information registration means. And an authentication step of establishing communication only when they match with each other, thereby establishing a wireless communication method.

FIG. 8 is a diagram showing a portable telephone 0 and an external device 2 in the wireless communication system Z1.
It is a state transition diagram of 0.

[0010] Wireless communication system Z1 according to the present embodiment.
Is composed of a mobile phone 0 and an external device 20, as shown in FIG. The mobile phone 0 includes a telephone unit 1 that functions as a conventional mobile phone, another local wireless control unit 2, a connection request unit 3, a registration request unit 4, a deletion request unit 5, an identifier storage unit 6, and a registration unit. The information storage unit 7 is provided. The components other than the telephone unit 1 may be built in the housing of the mobile phone 0, or may be configured as a detachable unit outside the mobile phone 0. The external device 20 is assumed here to be a hands-free device, an Internet terminal device, or a vehicle-mounted external device that combines them. ), And other local wireless control units 22, authentication information registration units 23, authentication units 24, standby processing units 25, identifier storage units 26, and authentication information storage units 27. ing.

First, a schematic configuration of each section of the portable telephone 0 will be described. The local wireless control unit 2 controls wireless communication with the local wireless control unit 22 of the external device 20. Here, the wireless communication based on Bluetooth described above is assumed, but the present invention is not limited to this.
Prior to performing wireless communication with the external device 20, the registration request unit 4 provides the external device 20 with its own unique identifier (mobile phone identifier) and an identifier of a service that the external device 20 wants to use. (Service identifier) and the identifier of the external device of the partner (external device identifier) are transmitted to make a registration request. It is assumed that the mobile phone identifier is stored in the identifier storage unit 6 in advance. Here, as the mobile phone identifier, for example, a telephone number or a serial number of the mobile phone may be used, or an arbitrary number may be set by a user. It is desirable for the user to register the external device identifier as a personal identification number in advance in order to restrict the registration from an unspecified person. For example, a serial number may be used. The registration request unit 4
In response to the registration request, the portable telephone is connected to the external device 20.
Is registered in the registration information storage unit 7 (registered external device identifier, service identifier, etc.). The deletion requesting unit 5 requests a predetermined external device 20 to delete the registration already performed. When the registration is deleted by the deletion request from the deletion request unit 5, the registration information is deleted from the registration information storage unit 7. The connection request unit 3 transmits a connection request to the external device 20 already registered by the registration request by the registration request unit 4 together with its own mobile phone identifier and the service identifier of the desired service. This connection request is transmitted, for example, when there is an incoming call to the telephone unit 1 or when the call button of the mobile phone 0 is pressed. In the wireless communication system Z1 according to the present embodiment, the connection request is made only from the mobile phone 0 to the external device 20 in order to suppress battery consumption on the mobile phone 0 side (details will be described later).

Next, a schematic configuration of each unit on the external device 20 side will be described. The local wireless control unit 22 controls wireless communication with the local wireless control unit 2 of the mobile phone 0 as described above. When the authentication information registration unit 23 receives a registration request from the registration request unit 4 of the mobile phone 0, the external device identifier transmitted with the registration request is stored in the identifier storage unit 26 in advance. Only when the mobile phone matches with the external device 20, a process of registering the mobile phone as a wireless communication partner with the external device 20 is performed.
When the registration of a certain mobile phone 0 is permitted, the registration information (the mobile phone identifier of the other party, the service identifier, etc.) is stored in the authentication information storage unit 27. The authentication unit 24 receives a connection request from the connection request unit 3 of the mobile phone 0,
An authentication process is performed to determine whether to permit the connection. In this authentication process, the mobile phone identifier sent together with the connection request matches the one stored in the authentication information storage unit 27, and the service identifier sent at the same time is stored in the authentication information storage unit 27 in the authentication information storage unit 27. The connection is permitted if it is included in one or more service identifiers stored corresponding to the mobile phone identifier. The standby processing unit 25 includes:
The switching of the external device 20 between the idle state and the standby state is controlled. The standby processing unit 25 includes, for example, a vibration sensor that detects a vibration of a vehicle on which the external device 20 is mounted.
From the idle state to the standby state. Conversely, if no vibration is detected for a predetermined time, the external device 20 is shifted from the standby state to the idle state.
As a result, the external device can be placed in the standby state only when the user can use the external device, and the battery consumption of the external device can be suppressed.

(Registration Processing Procedure: Corresponding to Authentication Information Registration Step) Subsequently, a specific procedure of the registration processing will be described with reference to FIGS. First, on the external device 20 side, the standby processing unit 25 detects the user's entry based on, for example, the presence or absence of vibration of the vehicle, and shifts from an idle state (or a stopped state) to a standby state (step S1). Of course, it is also possible to shift to a standby state by a user's button operation or the like. When accepting registration from mobile phone 0,
The external device 20 must always be in a standby state. Here, there are two types of the standby state, a standby state for a registration request and a standby state for a connection request described later, which are responded to when the request from the mobile phone 0 is received. What is necessary is just to select a standby state. The user performing the registration process sets the mobile phone 0 to the “registration process request” mode by a function operation or the like (step S2). At this time, on the display of the mobile phone 0, a screen for requesting input of an external device identifier of the external device 20 to be registered is displayed, for example, as indicated by D1 in FIG. When the user inputs an external device identifier (for example, a personal identification number) in response to the input request, a registration request message and the external device identifier are transmitted to the external device 20 by the registration requesting unit 4 of the mobile phone 0 (step). S
3). Upon receiving the registration request, the authentication information registration unit 23 of the external device 20 stores the received external device identifier in the identifier storage unit 2.
If the identifier matches the identifier stored in advance in step 6, the registration processing start message (ACK message) is transmitted to the mobile phone 0 of the other party. At this point, communication between the external device 20 and the mobile phone 0 regarding the registration process is established.
On the other hand, if the received external device identifier does not match the identifier stored in the identifier storage unit 26 in advance, the authentication information registration unit 23 transmits a registration processing rejection message (NACK message) to the mobile phone 0 of the other party. (Step S4).

When the mobile phone 0 receives the NACK message from the external device 20, a registration rejection message such as D2 in FIG. 3 is displayed on the display, and the process ends. On the other hand, when an ACK message is received from the external device 20, a display screen of the mobile phone 0 displays a service identifier input request screen, for example, as indicated by D3 in FIG. When the user inputs one or more service identifiers (for example, the service identifier "1" indicates hands-free) in response to the input request, the registration request unit 4 causes the external device identifier of the other party (input at the beginning of the registration request). The mobile phone identifier stored in the identifier storage unit 6 and the service identifier input by the user are transmitted to the external device 20 of the partner (step S5).
The authentication information registration unit 23 of the external device 20 checks again whether or not the external device identifier received from the partner mobile phone 0 matches the identifier stored in the identifier storage unit 26. The mobile phone identifier and the service identifier received from the other party's mobile phone 0 are associated with each other and stored in the authentication information storage unit 27, and a registration acceptance message is transmitted to the other party's mobile phone 0.
If the external device identifier received from the partner mobile phone 0 does not match the identifier stored in the identifier storage unit 26, the authentication information registration unit 23 transmits a registration rejection message to the partner mobile phone 0 ( Step S6).
The registration request unit 4 of the mobile phone 0 transmits the external device 0 of the partner.
When a registration acceptance message is received from
4 and outputs the registration destination external device identification number and service identifier in the registration information storage unit 7. On the other hand, when a registration rejection message is received from the external device 0 of the partner, the registration request unit 4
For example, a message as shown in D5 of FIG. 3 is output, and the process ends (step S7).

(Registration Deletion Procedure) Next, referring to FIG.
A specific procedure of the deletion processing of the registered information already registered will be described. Also in the case of this deletion processing, the external device 20 side needs to be in a standby state. The user who performs the deletion processing first sets the mobile phone 0 to the “registration deletion processing request” mode by a function operation or the like. At this time, a list of registration information (external device identifier and service identifier) stored in the registration information storage unit 7 is displayed on the display of the mobile phone 0, for example, as indicated by D11 in FIG. When the user selects the registration information to be deleted from the list and performs an execution operation, the deletion request unit 5 sends the external device identifier, the service identifier and the identifier storage unit 6 selected by the user to the external device 20. Then, a deletion request message is transmitted together with the mobile phone identifier stored in (step S11). Upon receiving the deletion request message, the authentication information registration unit 23 of the external device 20 determines that the received external device identifier matches the identifier stored in the identifier storage unit 26 and that the received mobile phone identifier and service identifier If exists in the authentication information storage unit 27, the registration information is deleted from the authentication information storage unit 27 and a success code is transmitted to the mobile phone 0 of the other party. On the other hand, the external device identifier received from the other party's mobile phone 0 does not match the identifier stored in the identifier storage unit 26, or the combination of the mobile phone identifier and the service identifier to be deleted is stored in the authentication information storage unit 27. If not, the authentication information registration unit 23 transmits a failure code to the other party's mobile phone 0 (step S12).
The above-mentioned deletion request unit 5 of the mobile phone 0 transmits the external device 0 of the partner.
When a success code is received from the registration information storage unit 7, a message as indicated by D12 in FIG. 4 is output, and the registration information to be deleted is deleted from the registration information storage unit 7. On the other hand, if a failure code is received from the external device 0 of the partner, the deletion requesting unit 5 outputs a message such as D13 in FIG. 4 and ends the process (step S13).

(Connection Establishment (Authentication) Procedure: Corresponding to an Authentication Step) Subsequently, referring to FIGS.
A description will be given of an authentication procedure at the time of establishing a connection when using this service. First, the procedure at the time of transmission will be described with reference to FIGS. As for the procedure at the time of the incoming call, only the parts different from those at the time of the outgoing call will be described later. External device 2
On the 0 side, the standby processing unit 25 detects the user's entry based on, for example, the presence or absence of vibration of the vehicle, and shifts from an idle state (or a stopped state) to a standby state (step S2).
1). Of course, it is also possible to shift to a standby state by a user's button operation or the like. If the external device 20 is not in the standby state, the connection request from the mobile phone 0 cannot be accepted. The standby state may be either a standby state for a registration processing request or a standby state for a connection request, and may be switched according to the content of the request received from the mobile phone 0. The user performing the calling process sets the mobile phone 0 to the “call request” mode by a function operation or the like (step S2).
2). At this time, the external device 20 to be connected is displayed on the display of the mobile phone 0, for example, as indicated by D21 in FIG.
Is displayed. For example, when the mobile phone 0 is registered in only one external device 20, the mobile phone 0 specifies only one external device identifier of the other party from the information stored in the registration information storage unit 7. Therefore, it is not always necessary to display the input request screen. For example, when the user inputs an external device identifier (for example, a password) in response to the input request, a connection request message is transmitted to the external device 20 by the connection request unit 3 of the mobile phone 0 (step S23). External device 2 receiving the connection request
The authentication unit 24 of the other mobile phone 0 sends a connection processing start message (ACK) to the other mobile phone 0 except in a special case such as when a new connection request cannot be received during the authentication processing of another mobile phone 0. Message) (step S24). At this point, the external device 20 related to the connection process
Communication between the mobile phone 0 is established.

Upon receiving the ACK message from the external device 20, the mobile phone 0 displays a service identifier input request screen, such as that shown at D22 in FIG. 6, on the display. When the user inputs one or more service identifiers (for example, service identifier “1” indicates hands-free) in response to the input request, the connection request unit 3
Thus, the mobile phone identifier stored in the identifier storage unit 6 and the service identifier input by the user are transmitted to the external device 20 of the other party (step S25). The authentication unit 24 of the external device 20 first determines whether or not the mobile phone identifier received from the partner mobile phone 0 is stored in the authentication information storage unit 27 (that is, whether or not the mobile phone is a registered mobile phone). If the service identifier has been registered, the subsequently received service identifier is stored in the authentication information storage unit 27.
It is determined whether or not the service is included in the service identifier group stored in (i.e., whether or not the service is a registered service). If the mobile phone identifier or the service identifier is not registered in the authentication information storage unit 27, the external device 20 transmits a NACK message (connection rejection message) to the other mobile phone 0 and accepts the registration process. Transition to a standby state such as a mode. The message of D23 in FIG. 6 is displayed on the display of the mobile phone 0 that has received the NACK message. On the other hand, if the mobile phone identifier and the service identifier are registered in the authentication information storage unit 27, the external device 20
Transmits an ACK message (connection authentication message) to the other party's mobile phone 0 and provides the requested service (step S26).

The above is the authentication procedure at the time of calling. The authentication procedure for incoming calls is almost the same, but
There is a slight difference in the stage of transmitting a connection request from the mobile phone 0 to the external device 20. That is, a connection request is transmitted by a button operation or the like by the user at the time of outgoing call, but at the stage of receiving an incoming call, a connection request message is automatically transmitted to the external device 20 when the mobile phone 0 detects the incoming call. The external device 20 of the transmission partner is automatically determined based on the registration information stored in the registration information storage unit 7.
The processing after transmission of the connection request is exactly the same as the procedure at the time of transmission (see FIG. 7).

(Standby Process) Next, referring to FIG. 8, the portable telephone 0 and the external device 2 in the wireless communication system Z1 will be described.
The state transition of 0 will be described. First, the external device 20
For example, the state shifts from the idle state to the standby state by detection of a boarding event such as vibration of a car or by a button operation of the user. The standby state is maintained until a drop-off event, for example, in which the vibration of the car cannot be detected for a predetermined period of time or the like, or until the user operates the standby release button. Then, for example, when a connection request is received from the mobile phone 0 and the authentication is successful, communication with the mobile phone 0 is established. When the authentication fails or the communication ends, the state shifts to the standby state again. However, the external device 20 performs a process of waiting for a connection request from another mobile phone 0 in parallel while the communication with the certain mobile phone 0 is established. This allows, for example, a plurality of users to use different services (for example, hands-free and Internet connection) of one external device using their own mobile phones.
On the other hand, the mobile phone 0 does not wait for a connection request from the external device 20 and normally stops the local wireless function in a stopped state. Then, when there is an incoming call or a call request from the user, a connection request is transmitted to the external device 20, and if the external device 20 succeeds in authentication, communication is established. . If the authentication has failed on the external device 20 side or the communication has ended, the state shifts to the stop state again. As described above, in the present wireless communication system Z1, a connection request for establishing wireless communication between the mobile phone 0 and the external device is always made from the mobile phone 0 to the external device 20, so that the mobile phone 0 0 does not need to maintain a state of waiting for a connection request from the external device 20. Therefore, there is no power consumption associated with the standby state of the mobile phone 0, and the limited battery capacity can be used effectively. Also, the external device 20 does not always maintain the standby state, and the user operates the external device 20.
Since the transition from the idle state to the standby state is performed only in a state in which is available (here, when the user gets on the vehicle), power consumption can be minimized.

As described above, according to the wireless communication system Z1 according to the present embodiment, only the mobile phone registered in advance on the external device side can communicate with the external device. Confidentiality ”
By registering a plurality of mobile phones in advance, "sharing" such that one external device is used by a plurality of mobile phones is also realized. In addition, since a connection request for establishing wireless communication between a mobile phone and an external device is always made from the mobile phone to the external device, the mobile phone consumes power for waiting for a connection request from the external device. There is no, and the limited battery capacity can be used effectively. In addition, the external device does not always maintain the standby state, but shifts from the idle state to the standby state only when the user can use the external device (here, when the user gets on the vehicle). It can be minimized.

[0021]

[Embodiment] With the configuration as in the above embodiment, for example, when using an external device having a plurality of functions, it is desirable to be able to simultaneously communicate with a plurality of mobile phones.
For example, considering a car navigation system having a hands-free function and an Internet terminal function as an example of an external device, a driver can communicate with a plurality of mobile phones at the same time, and the driver can use the hands-free mobile phone with the mobile phone. The user can make a call using the function, and the passenger can use the mobile phone to connect to the Internet. Further, in the above-described embodiment, the example in which the transition of the external device to the standby state is performed based on the detection of the vibration is described. However, other examples include the start / stop of the engine and the sensor of detecting the approach of the user. A method of shifting the external device to a standby state based on the output may be considered. Furthermore, in the above-described embodiment, an example has been described in which registration processing to an external device is performed using a mobile phone, but it is also possible to perform registration processing directly to an external device by operating a button or the like. In addition, the external device is not limited to the above-described in-vehicle device, but may be any device that can be connected to a mobile phone, such as a personal computer or a music distribution terminal.

[0022]

As described above, the wireless communication system according to the present invention, the external equipment constituting the wireless communication system, the portable telephone,
According to the wireless communication method, only the mobile phone registered in advance on the external device side can communicate with the external device, so that "confidentiality" of communication is ensured, and a plurality of mobile phones can be connected in advance. By registering, "shared property" such that one external device is used by a plurality of mobile phones can be realized. If a connection request for establishing wireless communication between a mobile phone and an external device is always made from the mobile phone to the external device, the mobile phone waits for a connection request from the external device. Power consumption can be reduced to zero, and limited battery capacity can be used effectively. In addition, the power consumption of the external device can be minimized by shifting from the idle state to the standby state only when the user can use the external device instead of always maintaining the standby state. Is possible.
