Next, FIG. 5 shows a protocol stack for communication between devices corresponding to the BT system.

In the physical layer (R / F 501), digital data is converted into analog data and transmitted from an antenna. The primary modulation is performed in accordance with the sequence of digital data 0 and 1, and the primary modulation is further transmitted on a 2.4 GHz band carrier. The carrier is constantly switched by frequency hopping, which changes the frequency for each transmission (slot) of one data.

Data transmission and reception are performed alternately for each slot. In the receiving slot, after removing the carrier in the 2.4 GHz band from the signal received by the antenna, demodulation is further performed to extract digital data in the 0, 1 sequence. The frequency of the carrier to be removed is constantly changing due to frequency hopping, but depending on the communication partner,
The hopping sequence is known in advance.

The main role of the link layer (Baseband 502) is to control data retransmission.

Various communication information is added to the original data and sent to the destination. When data is received,
Reply if it was received correctly. If not received correctly, request retransmission. If no matter how many times you send data, the other party cannot receive it, give up on a certain number of times. When the receiving buffer overflows, it requests the other party to temporarily stop transmission.

In addition to the information related to the communication control, a code for error detection / correction is added to the data in order to make the data resistant to errors occurring in the communication path.

The link layer (LMP (Link Management Protocol)

Mode control according to the presence / absence of data to be transmitted / received, communication frequency, etc. Communication channel status Switching of packet types according to authentication Authentication of whether data communication is permitted Encrypts data communication.

The link layer (L2CAP (Logical Link Cont
In rol & adaptation protocol (504), a logical channel is defined. The connection between two BT communication devices is physically connected by one communication path, and a plurality of logical channels can be defined there. As a result, data of various types of higher-level protocols can be transmitted and received simultaneously. When the data size passed from the upper layer protocol is large, the data size is subdivided into packet sizes defined by Baseband 502. On the sending side, it is sent in fragments, and on the receiving side, it is reconstructed into the original large chunk.

The link layer L2CAP 504 also exchanges information with the BT device of the communication destination regarding the data transfer rate and the speed of response to transmission.

The transport layer (A / V protocol 50)
In 5), commands for controlling transmission / reception of music data and image data in BT communication and for controlling A / V devices are defined, and FIG.
, The destination ID, the sender ID, the response / command, the content of the command and the CH. A in which control command information composed of NO and the like is subdivided for transmission and put in the payload portion of a Baseband packet in BT communication
/ V protocol packets are generated, and for music and image data, formats such as the type (MP3, ATRAC, MPEG4) and quality (transfer rate, compression rate) of data to be transferred as a stream are determined. As shown in the figure, the format and data
A data packet is generated in the payload portion of the seband packet. As the control command, commands related to state control of the A / V device, such as playback, stop, pause, and fast forward, are defined.

Transport layer (A / V protocol 50)
In the application layer (506) above 5), a program related to an operation actually performed by each device is described. This part differs for each device.

In the telephone 100 of this embodiment, by operating the A / V device by remote control, the surrounding A / V device is stopped when a call is received, and the user of the A / V device is notified of the incoming call.

The CD player main body 210 transmits the reproduced music to the headphones 240 with remote control. Further, in response to a control command from the headphone 240 with remote control or the telephone 100, the CD player is temporarily stopped, muted, and the like.

The headphones 240 with remote control reproduce music received from the CD player main body 210. Also,
The result of the user operating the command button 249 is indicated by A /
It is transmitted to the CD player body 210 as a V control command.

The telephone 10 based on the BT protocol
FIG. 8 shows a communication flow between the portable CD player 200 and the portable CD player 200. It is divided into the first half until a link is established to enable data communication, and the second half where a remote control signal is sent from the telephone set 100 to the CD player main body 210.

First, the telephone set 100 issues an inquiry message and collects information on peripheral devices (S1).

The device that has received the inquiry message replies with an FHS packet (S2).

In the FHS packet, as shown in FIG.
BD_ADDR (Bluetooth Device Address), CoD (Cl
ass of Device). BD_ADDR is a 48-bit ID assigned to the device. Equipment 1
Only one code is assigned to each one. CoD
Indicates what the device is. Based on this information, the telephone 100, the CD player main body 210, the headphone 240 with remote control, and the like are identified.

When the telephone has collected information on the peripheral devices,
The device to be controlled (here, the CD player body 21
0), a connection is established.

The first step for this is transmission of a Page message (S3). The Page message includes BD_ADDR of the device to be connected.

For the Page message, BD_A
The device specified by the DDR, that is, the CD player body 210 returns a Response (S4).

When the telephone set 100 receives a response from the CD player main body 210, the FHS packet contains information for the CD player main body 210 to participate in the piconet having the telephone set 100 as a master, and the telephone set 100
(S5). Here, "piconet" is B
In the word of T communication, it is a star network formed around one master device. Devices other than the master are called slaves. In the FHS packet, the telephone 100 as the master is the CD
The ID in the piconet assigned to the player main body 210 is included. This ID is AM_ADDR (Active Member A
ddress), up to 7 (1-7) in one piconet
Assigned. Further, information of a master frequency hopping sequence and clock phase is included. In the subsequent data communication, the CD player body 210
The information of the frequency hopping and the clock notified by the FHS packet is used.

The telephone 100 and C
The frequency hopping sequence and the phase of the clock match between the D player main bodies 210, and the D player main body 210 is in a physically communicable state. A state in which AM_ADDR is assigned and communication is always possible is called an active mode.

Next, a connection request for actually controlling the CD player 210 is issued from the telephone set 100 (S
7).

The CD player main body 210 is a telephone (for example, a telephone of the owner of the CD player) 10 which has been notified in advance.
Issue an authentication request to allow control only from 0 (S
8).

In the authentication, the telephone 100 sends an authentication value calculated based on a password set in advance with the CD player body 210 (S9).

In the BT, a PIN (Personal Identification Number) corresponds to this password.

If the authentication procedure is successful, the CD player main body 210 notifies the telephone 100 of the success (S10).

Thereafter, it becomes actually possible to control the CD player main body 210 from the telephone set 100.

However, in this embodiment, the control of the CD player main body 210 from the telephone set 100 is as follows.
Only when there is an incoming call. So, the telephone 10
BT communication of the CD player main body 210 with respect to
Enter the k mode (S11, S12).

When entering the Park mode, the CD player body 210 disconnects from the piconet with the telephone set 100 as the master, and releases the assigned AM_ADDR. The frequency hopping sequence and the phase of the clock should be kept synchronized with the communication within the piconet so that it can immediately return to the piconet later.

When there is an incoming call,
When it becomes necessary to control the D player main body 210, the BT communication of the CD player main body 210 to the telephone set 100 is returned from the Park mode to the Active mode (S
13, S14). At this time, a free AM_ADDR in the piconet having the telephone set 100 as a master is allocated to the CD player main body 210.

Thereafter, the transmission of the A / V control command from the telephone set 100 (S15) and the reception of the response from the CD player main body 210 (S16) are repeated, and upon completion, the CD player main body 210 is returned to the Park mode again (S17, S18).

Next, a communication procedure between the three BT communication devices will be described with reference to FIG. 10 showing a communication flow between the three BT communication devices, ie, the telephone set 100, the CD player main body 210, and the headphone 240 with a remote controller. .

As a premise, as shown in FIG. 11, two piconets P1 and P2 exist between three devices, and the CD player main body 210 belongs to both. In BT,
A collection of piconets with some devices overlapping is called a scatter net. One is a piconet P1 in which the CD player main body 210 is the master and the headphones 240 with the remote control are the slaves. The basic operation is to transmit music data from the CD player 210 to the headphones 240 with remote control. When the user operates the remote controller, an A / V control command is sent from the headphones with remote controller 240 to the CD player main body 210. The other is that the telephone 100 is a master and the CD player body 210
Is a piconet P2 having as a slave.

As shown in the communication flow of FIG. 8, the CD player main body 210 in the piconet P2 basically
You are in ark mode. When there is an incoming call, the CD player 210
Only when it is necessary to stop the reproduction of the CD player, the CD player main body 210 enters the Active mode and performs data transmission and reception.

Note that the CD player body 210 is Park
The mode is entered for the BT communication with the telephone 100 and the B
The T communication is different.

First, the CD player main body 210 transmits music data to the headphones 240 with remote control (S21).

When a call is received on the way, the telephone 1
00 sets CD player body 210 from Park mode to A
Set to the active mode (S22, S23).

Then, a pause command is sent (S2
4).

The CD player main body 210 executes an operation according to the command, and notifies the result (S25). At this point, data transmission from the CD player main body 210 to the headphones 240 with remote control stops.

Thereafter, the telephone set 100 sets the CD player main body 210 again in the Park mode (S26, S2).
7).

The CD player body 210 that has been paused
Is set to the playback operation state, the user operates the headphones 240 with remote control. When the reproduction command is sent to the CD player main body 210 (S28), when the reproduction is started (S29), the music data is transmitted from the CD player main body 210 to the headphones 240 with the remote control again (S30).

As described above, the incoming call notification can be realized using the telephone 100 having the BT communication function and the A / V device. A / V from telephone 100
When a command for controlling the device can be transmitted, the reproduction of the surrounding audio device is stopped at the time of the incoming call, and the telephone 1
The user can easily notice that 00 is sounding.

Further, if the A / V stream can be transmitted from the telephone, the ringing tone at the time of the incoming call is changed to the surrounding A / V.
It is possible to realize an incoming call notification function by sending the notification to a speaker or headphones of the V device.

For example, when an incoming call arrives at the telephone at home, a ringing tone is made to sound from a stereo speaker located at a different location from the room where the telephone is located. It is assumed that the telephone, the stereo body, and the speaker all support BT communication. The telephone stops the music reproduction on the stereo main body by operating the remote control, and then transmits a ringing tone to the speaker. In this way, the incoming call can be recognized from a remote room without increasing the ring volume of the telephone.

The telephone 100 described in this embodiment,
CD player body 210, headphones 24 with remote control
The same can be done with a combination of zero. When a call is received, the music playback on the CD player main body 210 is stopped by a remote control operation from the telephone set 100, and then a ringing tone is transmitted to the headphones 240 with the remote control. By doing this,
Even if the ringing tone of the telephone 100 is off, if the user is using the headphones 240 with the remote control, the incoming call can be recognized.

Here, in the result of inquiry (S2) in the communication flow shown in FIG.
Only the CD player main body 210 was controlled from 0.

If there are a plurality of objects to be controlled from the telephone set 100 and it is desired to control them all at the time of an incoming call,
After receiving the nquery result (S2), S3 to S
The processing up to 12 is performed for each device to be controlled. Then, when a call is received, the processes from S13 to S18 are performed for each device to be controlled.

Further, in the communication flow shown in FIG.
If the telephone 100 already knows the information of the partner device to be connected from the beginning, the device search process can be omitted. That is, the communication of S1 and S2 can be omitted.

Further, it is also possible to use the CD player body 210 such that it accepts control from all devices without authentication. In this case, S8 and S9 are omitted.

Further, it is possible to omit the transition of the connection between the telephone 100 and the CD player body 210 to the Park mode. FIG. 12 shows a communication flow in that case.

Here, it is assumed that telephone 100 has C
It is assumed that BD_ADDR, CoD, etc. of the D player main body 210 are known in advance. Therefore, the telephone 100
In order to establish a link with the CD player body 210, Pa
The process starts from the issue of the ge command (S51).

The CD player body 210 that has received the Page command returns a Response (S52).

[0094] The telephone 10 that has received the Response
0 sends an FHS packet to the CD player main body 210, AM_ADDR, a frequency hopping sequence,
Information such as the phase of the clock is notified (S53).

After the CD player having received the FHS packet returns a response (S54), a physical link between the telephone set 100 and the CD player 210 is established, and BT communication becomes possible.

Next, a logical connection request for enabling the CD player main body 210 to be actually controlled is issued from the telephone set 100 (S55).

The CD player main body 210 is
An authentication request is returned to (S56). This is to prevent unintentional control from an unspecified device.

Upon receiving the authentication request, the telephone set 100 sends the calculated authentication value to the CD player body 210 (S5).
7), the CD player body 210 that has received the authentication performs authentication.

When the authentication procedure is successful, the CD player main body 210 notifies the telephone 100 of the fact (S58).

Thereafter, it becomes actually possible to control the CD player main body 210 from the telephone set 100.

However, in this embodiment, the control of the CD player main body 210 from the telephone set 100 is as follows.
Only when there is an incoming call. Otherwise,
A POLL packet is periodically sent from the telephone set 100 to the CD player main body 210 (S59). Upon receiving the POLL packet, the CD player body 210 receives the
nse is returned (S60).

The POLL packet is used for the purpose of checking whether the slave device (in this example, the CD player main body (210)) is within the communication range, and the master device (in this example, the telephone 100) checking.

When the telephone 100 controls the CD player body 210, transmission of an AV control command (S61),
