  On the other hand, the rear terminal 2 is connected to the above-described in-vehicle communication module 1 through the cable 4 (the serial data line 41 and the RI signal line 42 through which the RI (Ringing Indicator) signal propagates). The rear terminal 2 exchanges data with the in-vehicle communication module 1 via the serial data line 41 by USB (Universal Serial Bus) communication and receives the RI signal from the in-vehicle communication module 1 via the RI signal line 42. In this case, it has a function of transitioning from the hibernation state to the operation state. Details will be described later.

Here, the relationship between the CDMA2000 1x communication network 3, the in-vehicle communication module 1, and the rear terminal 2 is shown. Yes. The sequence diagram shown in FIG. 2 also shows each step of the standby method in the communication apparatus of the present invention.
The operation of the communication apparatus according to the embodiment of the present invention will be described in detail below with reference to the sequence diagram shown in FIG.

Here, it is assumed that the in-vehicle communication module 1 has been contracted with a communication carrier, has a unique ID such as a telephone number, and a certain user makes a call to this ID. At this time, the CDMA2000 1x communication network 3 side including the base station transmits a voice incoming signal to the corresponding in-vehicle communication module 1 according to the position registered information (step S201).
However, as described above, when the in-vehicle communication module 1 is set in the power saving SMS incoming standby mode, it does not accept incoming voice calls in the standby state. A NAK response is returned (step S202). The CDMA2000 1x communication network 3 that has received the NAK response determines that the in-vehicle communication module 1 is in the power saving incoming call standby state (power saving SMS incoming standby mode), and immediately receives a packet (voice incoming) SMS) is transmitted (step S203).

  The CDMA2000 1x communication network 3 may send a voice incoming SMS from the beginning without sending a voice incoming signal. However, when the in-vehicle communication module 1 is in operation and is waiting in a voice incoming mode. Since the response speed decreases, it is preferable to send a normal voice incoming signal first. Further, when the in-vehicle communication module 1 is in a power saving standby state (power saving SMS incoming standby mode), the same effect can be obtained even with NOP without returning a NAK response, which can contribute to further power saving.

  The control circuit 13 that has received the voice incoming SMS via the RF filter 11 and the RF circuit 12 stores the message in the built-in memory 130 (step S204). Subsequently, the control circuit 13 notifies the succeeding terminal 2 of an incoming call by sending an RI signal via the control signal line 42 (step S205). Since the RI signal becomes active, the rear terminal 2 can return from the hibernation state to the operation state by interruption or the like (step S206).

The rear terminal 2 that has entered the operating state first transmits an SMS download request to the in-vehicle communication module 1 (control circuit 13) (step S207). The in-vehicle communication module 1 (control circuit 13) that has received this SMS download request knows that the rear-end terminal 1 has transitioned to the operating state (step S208), and passes the RF circuit 11 to the CDMA2000 1x communication network 3 side. In step S209, an SMS reception ready signal is transmitted. The CDMA2000 1x communication network 3 side receives this SMS reception enable signal and waits for the arrival of a voice incoming mode enable signal (to be described later) (step S210).
Thereafter, the in-vehicle communication module 1 (control circuit 13) reads the message stored in the built-in memory 130 and provides the download to the rear terminal 2 as a response to the previous SMS download request (step S211). ). The succeeding terminal 2 decodes the message (SMS) acquired by the download (step S212), and the SMS transmitted from the CDMA2000 1x communication network 3 and stored in the memory of the in-vehicle communication module 1 is “voice incoming”. Is determined to be a packet (voice incoming SMS), the voice incoming mode valid request is transmitted to the in-vehicle communication module 1 (step S213).

The in-vehicle communication module 1 (control circuit 13) that has received the voice incoming mode valid request validates the voice incoming mode and transitions to the voice call mode by circuit switching (step S214). Thereafter, a voice incoming mode enable signal is transmitted to the CDMA2000 1x communication network 3 side (step S215), and a voice call circuit ON request signal is transmitted to the rear terminal 2 (step S216).
The CDMA2000 1x communication network 3 side receives the voice incoming mode enable signal and transmits a voice incoming request (paging request) to the in-vehicle communication module 1 (step S217). The rear terminal 2 can activate the built-in voice circuit by receiving the voice call circuit ON request signal (step S218).

  Then, the in-vehicle module 1 (control circuit 13) that has received the voice incoming request signal from the CDMA2000 1x communication network 3 side activates the voice circuit 13 to start the voice incoming operation (step S219), and also via the data line 41. Then, a voice incoming signal is sent to the rear terminal 1 (step S220). Receiving the voice incoming signal, the rear terminal 2 starts ringer sound and informs the user of the voice incoming (step S221). The subsequent operation is a normally defined circuit-switching call operation, and the user can talk with the other party using the speaker 22 and the microphone 23 of the rear terminal 2.

According to the embodiment of the present invention described above, the communication device is configured by the in-vehicle communication module 1 and the rear terminal 2, and the key switch 21, the speaker 22, and the microphone 23 that the rear terminal 2 has are used. As the communication device of the present invention, the vehicle-mounted communication module 1 includes a speaker (SP), a microphone (M), and an amplifier, so that the vehicle-mounted communication module alone can receive a call. Function can be realized. Further, by preparing a switch (SW) or the like, it is possible to make a call to a specific telephone number such as an emergency call.
The rear terminal 2 includes a secondary battery 24 and supplies power to the in-vehicle communication module 1 by the secondary battery 24. In addition, the vehicle also includes a charger 25 (charging means) that stores power in the secondary battery 24 by having a generator, and the rear terminal 2 monitors the charging state of the charger 25, and the charger 25 When fully operating, paging standby is performed as in the past, and when it is not in operation, the power saving SMS incoming standby mode is set, so that incoming response can be flexibly controlled.

3 and 4 are flowcharts showing a power saving SMS standby processing procedure in the power saving SMS incoming standby mode by the in-vehicle communication module 1 of the communication apparatus according to the embodiment of the present invention.
Hereinafter, the power saving SMS incoming call waiting process procedure by the in-vehicle communication module 1 (control circuit 13) will be described in detail with reference to the flowcharts of FIGS.

The in-vehicle communication module 1 (control circuit 13) executes the power saving SMS incoming standby processing according to the following procedure by sequentially reading the SMS processing program stored in the built-in memory 130.
Specifically, the in-vehicle communication module 1 (control circuit 13) constantly monitors the arrival of a voice incoming signal from the CDMA2000 1x network 3 (step S301). Since the in-vehicle communication module 1 does not accept a voice incoming call in a standby state, when receiving a voice incoming signal (step S301 “Yes”), the in-vehicle communication module 1 returns a NAK response indicating that voice incoming is impossible to the CDMA2000 1x communication network 3. Alternatively, the state of NOP (No Operation) is maintained (step S302).

  On the CDMA2000 1x communication network 3 side including the base station, if the NAK response is received or if there is no response for a certain time, it is determined that the in-vehicle communication module 1 is in the power saving standby state (power saving SMS incoming standby mode) and immediately The control circuit 13 of the in-vehicle communication module 1 that has received the packet (voice incoming SMS) having the content “voice incoming is present” (step S303 “Yes”) receives the received voice incoming SMS. Save in the memory 130 (step S304). Subsequently, an RI signal is sent to the rear terminal 2 via the control signal line 42 (step S305), and the rear terminal 2 is returned from the sleep state to the operating state.

  Subsequently, the control circuit 13 receives the SMS download request from the rear terminal 2 (step S306 “Yes”), knows that the rear terminal 2 has changed to the operating state (step S307), and performs CDMA2000 1x communication. An SMS receivable signal is transmitted to the network 3 side via the RF circuit 12 and the RF filter 11. At this time, the CDMA2000 1x communication network 3 side including the base station receives this SMS reception ready signal and waits for the arrival of a voice incoming mode ready signal to be described later. Thereafter, the control circuit 13 reads the message (voice incoming SMS) stored in the built-in memory 130 as a response to the previous SMS download request to the rear terminal 2 and provides the download (step S308). .

Subsequently, it waits for the reception of the voice incoming mode valid request transmitted from the rear terminal 2 (step S309 “Yes”), enables the voice incoming standby mode, and shifts to the voice call mode by circuit switching (S310). Thereafter, a voice incoming mode enable signal is transmitted to the CDMA2000 1x communication network 3 side, and a voice call circuit ON request signal is transmitted to the rear terminal 2 (step S311 in FIG. 4).
Next, it waits for reception of a voice incoming request (paging request) transmitted from the CDMA2000 1x communication network 3 (step S312 “Yes”), activates the voice circuit 13 and starts a voice incoming operation (step SS313). A voice incoming signal is transmitted to the rear terminal 1 via the data line 41, the speaker 22 of the rear terminal 2 is driven, and the ringer sound is controlled. Thereafter, the circuit-switched call operation is normally specified (step S314), and the user can talk with the other party using the speaker 22 and the microphone 23 of the rear terminal 2.

  As described above, according to the communication device of the present invention, the current consumption during standby can be significantly reduced by using the power saving SMS incoming standby state described above. This depends on the network side including the base station, but the SMS reception interval by packet can be longer than the standby interval by normal paging (for example, the former is several tens of seconds / times, the latter is (Several seconds / times), the standby current of the entire communication device can be reduced. In particular, the effect obtained when the engine is stopped is great, and the burden of power supply to battery-operated equipment can be reduced.
