[0003]

Generally, a radio call receiving unit for realizing a radio call receiving function and a mobile phone transmitting / receiving unit for realizing a mobile phone function are provided in a single housing, and these are connected by a signal line or a power line. When connected, noise generated by the synthesizer or the control CPU of the mobile phone transmission / reception unit flows into the radio call receiving unit via the signal line or the power supply line, thereby deteriorating the reception sensitivity of the radio call function. Further, these noises flow into the radio call receiving unit via the antenna of the radio call function. Therefore, in realizing a mobile phone device with a radio page, it is an issue how to reduce the deterioration of the reception sensitivity of the radio page receiver while the mobile phone transceiver is operating.

[0004] The present invention solves such a problem, and when the portable telephone transmitting / receiving section performs standby reception within the wireless zone area, or performs intermittent receiving operation outside the wireless zone area, the wireless communication is performed. It is an object of the present invention to provide a mobile phone device with a radio paging that does not cause deterioration of reception sensitivity of a paging receiver.

[0005]

According to the present invention, there is provided a portable telephone apparatus with a radio call, which performs a two-way communication with a base station by radio, and a standby state of the portable telephone transceiver within a wireless zone area. Control means for controlling an intermittent reception operation at the time of searching for a base station outside of the time zone or the radio zone area; a radio paging receiver for intermittently receiving a radio paging signal dedicated to paging; and an intermittent radio paging receiver. A second control means for controlling a reception operation, wherein the first control means compares the intermittent reception timing of the mobile telephone transmission / reception section with the intermittent reception timing of the radio call reception section. And means for stopping the intermittent reception operation of the mobile phone transceiver when the intermittent reception timing of the mobile phone transceiver matches the intermittent reception timing of the radio call receiver. And wherein the door.

[0006] The portable telephone transmitting / receiving section performs an intermittent reception operation when waiting in a mobile communication system wireless zone area or when searching for a base station after moving outside the wireless zone area. If the timing of this intermittent reception overlaps with the intermittent reception timing of the radio paging receiver, it causes noise in the radio paging receiver, and the sensitivity of radio paging reception deteriorates. Therefore, at such a timing, the intermittent reception operation of the mobile phone transmitting / receiving unit is stopped.

[0007] When the portable telephone transmitting / receiving section stops receiving operation during standby in the wireless zone area, it becomes impossible to receive an incoming signal to its own station. However, in general, the incoming signal is retransmitted in the cellular mobile communication system, so that when the radio call receiving unit goes into the non-receiving state, the operation stop of the mobile phone transmitting / receiving unit is released and intermittent reception is resumed, so that the retransmission is performed. Incoming call signals can be received. Therefore, incoming calls to the mobile phone are not stopped.

[0008]

FIG. 1 is a block diagram showing an embodiment of the present invention. The mobile phone device with wireless calling according to this embodiment includes a wireless calling unit 1 and a mobile phone unit 2, a wireless calling antenna 3 is connected to the wireless calling unit 1, and a mobile phone antenna is connected to the mobile phone unit 2. 4 are connected. The radio calling unit 1 includes a radio call receiving unit 5 and an intermittent reception timing generation unit 6, and the mobile phone unit 2 includes a mobile phone transmission / reception unit 7, an intermittent reception timing generation unit 8, an intermittent reception timing comparison unit 9, and an operation stop / A return control unit 10 is provided.

The radio call receiving section 5 intermittently receives a radio call signal exclusively for calling. Intermittent reception timing generator 6
Controls the intermittent reception operation of the radio pager 5 by generating an intermittent reception timing. The mobile phone transmission / reception unit 7 performs bidirectional communication with a base station wirelessly. The intermittent reception timing generator 8 generates a timing signal for controlling the intermittent reception operation when the mobile phone transceiver 7 waits in the wireless zone area or when searching for a base station outside the wireless zone area. The intermittent reception timing comparison unit 9 compares the intermittent reception timing of the radio call reception unit 5 with the intermittent reception timing of the mobile phone transmission / reception unit 7 based on the outputs of the two intermittent reception timing generation units 6 and 8. The operation stop / return control unit 10 stops the intermittent reception operation of the mobile phone transmission / reception unit 7 when the intermittent reception timing of the mobile phone transmission / reception unit 7 matches the intermittent reception timing of the radio call reception unit 5.

[0010] Hereinafter, PCR STD is used as a radio paging method.
-41, the system defined in the NTT paging system paging standard is used as a mobile communication system by PCR STD-
28. The operation will be described by taking a system (hereinafter, referred to as a PHS system) defined in the second generation cordless telephone system standard as an example.

FIG. 2 is a diagram for explaining the operation when the portable telephone unit 2 performs a standby operation within the wireless zone area of the PHS system, and shows the relationship between the radio call signal format and the operation timing. (A) is a radio paging signal format, (b) is a radio paging intermittent reception timing, (c)
Is a control channel configuration example of the PHS system (time axis is shown enlarged), (d) is the intermittent reception timing of the mobile phone,
(E) is an operation timing of the mobile phone transmitting / receiving unit 7.

In this example, the paging signal is composed of 15 groups, and a general paging receiver intermittently receives only the signal of the group to which the paging receiver belongs. In the radio paging section 1, the radio signal is received and demodulated by the radio paging receiving section 5 and output to the intermittent reception timing generating section 6. The intermittent reception timing generator 6 generates a radio paging intermittent reception timing for designating the operation of the radio paging receiver 5 at regular time intervals by receiving the synchronization signal of the group to which the own station belongs (FIG. 2). (B)). Here, it is assumed that the wireless calling unit 1 belongs to the group “2”.

In the portable telephone section 2, the portable telephone transmitting / receiving section 7 receives and demodulates the control channel (FIG. 2C), and outputs a received signal to the intermittent reception timing generating section 8. The intermittent reception timing generator 8 generates the intermittent reception timing (FIG. 2 (d)) of the mobile phone so that it can receive only the channel of the group to which it belongs among the paging channels and outputs it to the intermittent reception timing comparator 9. I do.

The intermittent reception timing comparing section 9 and the operation stop / return control section 10 compare the intermittent radio call reception timing and the intermittent reception timing of the mobile phone. 7 is generated to stop the reception of the mobile phone. As a result, the operation of the mobile phone transmission / reception unit 7 can be stopped at the time of intermittent reception of the radio paging unit 1 (FIG. 2E), and it is possible to avoid the occurrence of noise that causes the reception sensitivity of the radio paging to deteriorate. In the PHS system, generally, a paging channel including an incoming signal is subjected to retransmission control, so that an incoming signal to the self that could not be received can be received after recovery.

FIG. 3 is a diagram for explaining the operation of the PHS system by the mobile phone unit 2 outside the wireless zone area.
4 shows a relationship between a radio paging signal format and operation timing. (A) is a wireless call signal format, (b) is a wireless call intermittent reception timing, (c) is a mobile telephone intermittent reception timing, and (d) is an operation timing of the mobile telephone transmission / reception unit 7.

Outside the area of the wireless zone of the PHS system, the cellular phone unit 2 scans the control channel for searching for a base station, but intermittently performs this scanning operation for battery saving. FIG. 3C shows the timing of the intermittent operation of the mobile phone. This timing is generated by the intermittent reception timing generator 8 and is input to the intermittent reception timing comparator 9. The intermittent reception timing comparison unit 9 and the operation stop / return control unit 10 compare the intermittent radio call reception timing with the intermittent reception timing of the mobile phone. The mobile phone transmission / reception unit operation timing for stopping the operation is generated. Thereby, the operation of the mobile phone transmission / reception unit 7 can be stopped at the time of intermittent reception of the radio paging unit 1, and the occurrence of noise that causes deterioration of the reception sensitivity of the radio paging can be avoided.

[0017]

As described above, in the portable telephone device with a radio call according to the present invention, the timing of the intermittent reception of the portable telephone transmitting / receiving section overlaps the timing of the intermittent reception of the radio call receiving section. By stopping the intermittent reception operation, noise to the radio paging receiver is reduced,
This has the effect of preventing the sensitivity of radio call reception from deteriorating.
