Abstract

PURPOSE:To lower power consumption by allowing a radio telephone set to switch an intermission reception period to the extension mode when a signal other than the notice signal is not received for a prescribed time. CONSTITUTION:A radio connection device 5 sends a notice signal including position information to a radio telephone set 6 for each prescribed time. The radio telephone set 6 starts a reception period management timer of the radio telephone set when the talking is finished, confirms the state of reception and the state of transmitter other than the notice signal and when the transmitter of the radio telephone set is not turned on and does not receive a signal other than the notice signal for a prescribed time set by the timer, the reception period is extended. Since it is possible to switch the intermittent reception period of the radio telephone set dynamically in response to the actual talking frequency or the like, the effect of intermittent reception aiming at low power consumption further improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to control for reducing power consumption of wireless telephones that operate on batteries, and particularly for wireless telephones. The present invention relates to a control method for switching an intermittent reception cycle when monitoring a broadcast signal including position information from a wireless connection device.

[Conventional technology]

The mobile communication system targeted by the present invention includes a wireless connection device,
The wireless telephone is wirelessly connected to this wireless connection device.

Conventionally, in such radio telephones, each radio telephone individually sets the power ON10FF ratio and the power ON10FF timing of the intermittent reception station M, that is, the receiver, based on the usage state of each radio telephone. Furthermore, in order to enhance the effect of intermittent reception, if the unused state continues for a long time, an extension mode is set in which the receiver's power supply 0N10 F F ratio is set longer than usual to further reduce power consumption. .

[Problem that the invention seeks to solve]

When performing intermittent reception in the conventional wireless telephone as described above, each wireless reception shore receives a signal for a certain period of time.
Control was such that when radio waves were not received, the system was set to extended mode, and then when radio waves (including notification signals) were received, it was switched to standard mode. Therefore, there may be cases where the intermittent reception cycle does not necessarily match the actual communication frequency, or even if there are fluctuations in call volume, it is unrelated (such as keeping a constant intermittent reception cycle). There was a problem in that the power consumption was low.

In view of these conventional problems, the present invention provides a control method that can dynamically switch the intermittent reception cycle according to the actual amount of calls, thereby further reducing power consumption. is intended to provide.

[Means for solving problems]

According to the invention, the above objects are achieved by the means specified in the claims.

That is, the most important feature of the present invention is that when the radio telephone determines that there is no signal other than the notification signal for a certain period of time, the intermittent reception period is switched to the 1-length mode.

In the conventional technology, switching between normal and extended mode was controlled depending on whether or not the wireless telephone received a radio wave in the dark for a certain period of time.However, in the method of the present invention, the wireless connection device is controlled from the wireless line controller. The difference is that the wireless telephone switches between the normal mode and the extended mode when it does not receive any signal other than the notification signal transmitted via i for a certain period of time.

〔Example〕

FIG. 1 is a system diagram explaining one embodiment of the present invention.

In Figure 1, the public telecommunications network (PS
T N ) or private branch network 1 consists of a local exchange (LS) accommodating general users or a private branch exchange (PABX) 2 accommodating only users within a company, and a subscriber transmission path or local branch network from the exchange 3 to the users. It is carried within the premises by a transmission line. 4 is a wireless line control device, 5 is a wireless connection device, 6 is a wireless telephone, 7 is a wired telephone connected to 2 LS or PABX by 10 wired lines, and the wireless line control Igt device 4 and the wireless connection device 5 is connected by 8 wired lines, and the wireless connection device I! 5 and wireless telephone 6 are connected by 9 wireless lines, and 2 LSs or PABXs are connected to 1 PSTN or local area network by 11 wired lines.

FIG. 2 is a diagram showing an example of the structure of a signal by which a wireless connection device notifies a wireless telephone of location information through a wireless line, in which 21 is a preamble signal, 22 is a word synchronization signal, and 2
3 indicates location information.

The operation of this embodiment will be explained below using the timing chart shown in FIG.

In Figure 3, <8) indicates the transmission/reception signal status of the wireless connection device, (b) the transmission/reception signal status of the W& line telephone, (c) the reception cycle of the receiver, and (d) the status of the reception cycle management timer. This is what is shown.

The wireless connection device 5 has means for transmitting a notification signal containing position information to the wireless telephone 6 at regular intervals. The radio telephone 6 has a function of managing the usage status of the transmitter of the radio telephone and also managing signal cycles other than notification signals. Then, this wireless telephone manages the status of the transmitter and receiver, and when the call ends, 1, it starts the reception cycle management timer of the wireless telephone and checks the reception cycle other than the notification signal and the status of the transmitter of this wireless telephone. If the transmitter of the radio telephone is not turned on and no signal other than the notification signal is received for a certain period of time set by this timer, the radio telephone extends the reception period.

〔Effect of the invention〕

As explained above, according to the present invention, wireless connection! In a mobile communication system in which a notification signal containing location information is sent to a telephone at regular intervals, and the wireless telephone intercepts the notification signal, the intermittent reception period of the wireless telephone is calculated as the actual call frequency. Since it is possible to dynamically switch depending on the situation, etc., the effect of intermittent reception aimed at lowering power consumption can be further enhanced.1! (There is.
