Abstract

PROBLEM TO BE SOLVED: To prevent deterioration in reception sensitivity of a radio call reception section by stopping an intermittent reception operation of a portable telephone set in the case that a timing of intermittent reception by a portable telephone set transmission/reception section and that of a radio call reception section are overlapped. SOLUTION: A radio call reception section 5 receives intermittently a radio call signal exclusive for calling. An intermittent reception timing generating section 6 generates an intermittent reception timing to control the intermittent reception of the radio call reception section 5. A portable telephone transmission reception section 7 uses a radio wave to make two-way communication with a base station. An intermittent reception timing generating section 8 generates a timing signal to control the intermittent reception in the case of a standby state of the transmission reception section 7 in a radio zone area or in the case of retrieval of a base station at the outside of a radio zone area. An intermittent timing signal comparator section 9 compares the intermittent reception timing of the reception sections 5, 7 based on outputs from the generating sections 6, 8. An operation stop/restoration control section 10 stops the intermittent reception operation of the transmission reception 7 when the intermittent reception timing of the transmission reception section 7 and that of the reception section 5 are equal.

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 one housing, and these are connected by a signal line or a power line. When the connection is made, noise generated in the synthesizer of the mobile phone transmitting / receiving unit or the control CPU flows into the radio call receiving unit through the signal line or the power line, and the reception sensitivity of the radio calling function is deteriorated. Further, these noises flow into the radio call receiving unit via the antenna of the radio call function. Therefore, how to improve the deterioration of the reception sensitivity of the wireless call receiving unit during the operation of the mobile phone transmitting / receiving unit is a problem in realizing the wireless calling mobile phone device.

The present invention solves such a problem, and when the portable telephone transmitting / receiving unit performs standby reception within the wireless zone area or when performing intermittent receiving operation outside the wireless zone area, the wireless communication is performed. An object of the present invention is to provide a mobile phone device with a wireless call that does not cause deterioration in reception sensitivity of a call receiving unit.

SUMMARY OF THE INVENTION A portable telephone device with wireless call according to the present invention is a portable telephone transmitting / receiving unit for performing two-way communication with a base station by radio, and waiting for the portable telephone transmitting / receiving unit within a wireless zone area. First control means for controlling the intermittent reception operation when searching for a base station at the time or outside the wireless zone area, a wireless call receiving section for intermittently receiving a wireless call signal dedicated to calling, and an intermittent operation for this wireless call receiving section. In a mobile phone device with a wireless call including a second control means for controlling a reception operation, the first control means compares the intermittent reception timing of the mobile phone transceiver with the intermittent reception timing of the wireless call receiver. And means for stopping the intermittent reception operation of the mobile phone transceiver when the intermittent reception timing of the mobile phone transceiver coincides with the intermittent reception timing of the radio call receiver. And wherein the door.

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

[0007] If the mobile phone transmitting / receiving unit stops the receiving operation during standby in the wireless zone area, it cannot 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 is in the non-reception state, the operation is stopped and the intermittent reception is restarted to retransmit the signal. Can receive incoming call signals. Therefore, the incoming call to the mobile phone is not stopped.

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 is 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 operation stop / operation. The recovery control unit 10 is provided.

The radio call receiving section 5 intermittently receives a radio call signal dedicated to a call. Intermittent reception timing generator 6
Controls the intermittent reception operation of the radio paging reception unit 5 by generating the intermittent reception timing. The mobile phone transmitting / receiving unit 7 wirelessly performs bidirectional communication with a base station. The intermittent reception timing generation unit 8 generates a timing signal for controlling the intermittent reception operation of the mobile phone transceiver 7 during standby 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 paging reception unit 5 and the intermittent reception timing of the mobile phone transmission / reception unit 7 from 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 transceiver unit 7 when the intermittent reception timing of the mobile phone transceiver unit 7 matches the intermittent reception timing of the radio call reception unit 5.

Hereinafter, PCR STD will be used as a radio calling system.
-41, the system defined in the NTT radio calling system standard is used as a mobile communication system in 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 mobile phone unit 2 performs the standby operation within the wireless zone area of the PHS system, and shows the relationship between the wireless call signal format and the operation timing. (A) is a radio call signal format, (b) is a radio call intermittent reception timing, (c)
Is a control channel configuration example of the PHS system (enlarged time axis is shown), (d) is a mobile phone intermittent reception timing,
(E) is the operation timing of the mobile phone transceiver 7.

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

In the mobile phone unit 2, the mobile phone transmitting / receiving unit 7 receives and demodulates the control channel (FIG. 2 (c)) and outputs the received signal to the intermittent reception timing generating unit 8. The intermittent reception timing generation unit 8 generates the mobile phone intermittent reception timing (FIG. 2D) 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 comparison unit 9. To do.

The intermittent reception timing comparison unit 9 and the operation stop / return control unit 10 compare the radio call intermittent reception timing with the mobile phone intermittent reception timing, and at the timing when the radio call intermittent reception timing is reception, the mobile phone transmission / reception unit. The mobile phone transmitting / receiving unit operation timing for stopping the reception of No. 7 is generated. As a result, the operation of the mobile phone transceiver 7 can be stopped during the intermittent reception of the wireless calling unit 1 (FIG. 2 (e)), and it is possible to avoid the generation of noise that causes deterioration of the reception sensitivity of the wireless calling. In the PHS system, since the paging channel including the incoming signal is generally subjected to the retransmission control, the incoming signal to itself which could not be received can be received after the 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.
The relationship between a wireless paging signal format and operation timing is shown. (A) is a radio call signal format, (b) is a radio call intermittent reception timing, (c) is a mobile phone intermittent reception timing, and (d) is an operation timing of the mobile phone transceiver 7.

Outside the wireless zone area of the PHS system, the mobile phone unit 2 scans the control channel for searching a base station, but this scanning operation is intermittently performed for battery saving. FIG. 3C shows the timing of this intermittent operation of the mobile phone, which timing is generated by the intermittent reception timing generation unit 8 and input to the intermittent reception timing comparison unit 9. The intermittent reception timing comparison unit 9 and the operation stop / recovery control unit 10 compare the radio call intermittent reception timing and the mobile phone intermittent reception timing, and when the radio call intermittent reception timing is the reception, the reception of the mobile phone transceiver unit 7 is performed. The operation timing of the mobile phone transmitting / receiving unit to stop is generated. As a result, the operation of the mobile phone transceiver 7 can be stopped at the time of the intermittent reception of the radio calling unit 1, and the generation of noise that causes the deterioration of the reception sensitivity of the radio calling can be avoided.

[0017]

As described above, in the portable telephone device with wireless call according to the present invention, when the intermittent reception timing of the portable telephone transmitting / receiving unit overlaps with the intermittent receiving timing of the wireless calling receiving unit, the portable telephone transmitting / receiving unit is activated. By stopping the intermittent reception operation, noise to the radio paging receiver is reduced,
This has the effect of preventing the sensitivity deterioration of radio call reception.
