Abstract

PURPOSE: To perform reception level measurement in a peripheral zone under the leadership of a mobile station and battery saving under the leadership of the mobile station. CONSTITUTION: The mobile station 101 sends a transmission stop request signal 211 to a base station, for example, when the speed of movement decreases below a predetermined constant value, and then stops receiving a signal. The base station 102 once detecting the reception of the transmission stop request signal 221 from the mobile station stops sending the signal. The mobile station and base station predetermine a stop time T, so the base station stops sending the signal for the stop time T after receiving the transmission stop request signal 221 from the mobile station. While the transmission from the base station is stopped, the mobile station measures the reception level in the peripheral zone. After the predetermined time T is elapsed, the mobile station and base station restart the signal reception and signal transmission respectively.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system including a network capable of bidirectional communication and a mobile station.

[0002]

2. Description of the Related Art In a mobile communication system, it is necessary to measure the reception level of a peripheral zone in order to control the zone shift accompanying the movement of a mobile station. This peripheral zone reception level measurement is performed according to the moving speed of the mobile station so that the measuring cycle is long when the moving speed of the mobile station is low and short when the moving speed of the mobile station is high. It is effective to change the measurement cycle.

Conventionally, the mobile station has a receiver for measuring the reception level in addition to the receiver for receiving the signal, and performs the reception level of the peripheral zone independently of the signal reception, or a predetermined method. The idle timing for stopping the transmission signal from the network is provided at every period, and the frequency of the receiver of the mobile station is switched at that time to measure the reception level in the peripheral zone.

[0004]

In the conventional method of measuring independently of signal reception, it is possible to change the reception level measurement cycle, but the mobile station must have two sets of receivers. There is a drawback that it is not possible to satisfy the conditions such as miniaturization and power consumption reduction required for the mobile station. In addition, in the method of providing idle timing,
In a general case where a wireless channel is shared by multiple mobile stations, idle timing cannot be provided at a frequency suitable for each mobile station.

Therefore, there is a drawback that the mobile station moving at low speed loses the transmission capability of the radio channel.

Further, in the conventional mobile communication system, since the mobile station has no means for requesting the network to stop or start the signal transmission, it is necessary to always receive the signal from the network. Therefore, when the battery capacity of the mobile station becomes low, the real-time property of signal reception is deteriorated, and the mobile station requests the network to stop or start signal transmission, and intermittently stops the operation of the radio to turn on the power. It was not possible to perform a so-called battery saving operation that reduces consumption.

It is an object of the present invention that the mobile station does not have a receiver for measuring the reception level of the peripheral zone, and the reception level of the peripheral zone is not provided by the network without fixed idle timing for stopping the signal transmission. It is to make measurements and to carry out battery saving led by mobile stations.

Embodiments of the present invention will be described below with reference to the drawings.

[Embodiment 1] FIG. 1 shows a system configuration in this embodiment. In FIG. 1, 101 is a mobile station existing in the zone, 102 is a base station forming the zone, 10
Reference numeral 3 indicates a zone. FIG. 2 shows the operation of this embodiment in the mobile station and the base station.

This embodiment will be described with reference to FIGS. 1 and 2. The mobile station 101 transmits a transmission stop request signal 221 to the base station 102 (S201), and then stops signal reception (S203). The base station 102 detects the reception of the transmission stop request signal 221 from the mobile station 101 (S211).
Then, the signal transmission is stopped (S212).

Since the mobile station 101 and the base station 102 predetermine the stop time T, the mobile station 101 stops signal reception for the stop time T after transmitting the transmission stop request signal 221, and the base station 102 , The signal transmission is stopped for the stop time T after receiving the transmission stop request signal 221 from the mobile station 101. While the transmission from this base station has stopped,
The mobile station 101 measures the reception level of the peripheral zone by using the receiver used for signal reception (S204).

When the predetermined time T ends, the mobile station 1
01, the base station 102 starts signal reception and signal transmission, respectively (S205, S213).

The transmission stop request signal 221 is set so that the measurement cycle becomes long when the moving speed of the mobile station is low.
Reduce the frequency (cycle) of sending. When the moving speed of the mobile station is high, the frequency of sending the transmission stop request signal 221 is increased.

The moving speed in the mobile station can be recognized by, for example, the following. This mobile station 10
In No. 1, the reception level from the base station 102 is constantly measured. The moving speed of the mobile station can be detected by using the result of the measurement of the reception level. This is because the reception level from the base station regularly changes so that there are peaks and troughs, and the mobile station can recognize the moving speed by measuring the speed of the change.

The stop time T is set to a time at which the mobile station can sufficiently measure the reception level in the peripheral zone.

[Second Embodiment] Further, in FIG. 1, both the mobile station 101 and the base station 102 may not predetermine the stop time T. This will be described with reference to FIG.

In this case, the mobile station 101 determines the stop time T, transmits the stop time included in the transmission stop request signal 321 (S301), and stops signal reception for the transmitted stop time T. When the time T passes, reception is started (S3
04). Then, during the stop time T, the mobile station 101
Measures the reception level in the peripheral zone (S30
3). This is done using the receiver used to receive the signal.

The base station 102 detects the reception of the transmission stop request signal 312 including the stop time from the mobile station 101 (S
311), the signal transmission is stopped for the received stop time T. After the stop time T, the transmission is restarted (S313).

In this embodiment, since the mobile station 101 has the right to determine the suspension period, the suspension period required by the mobile station can be set each time. Therefore, when the measurement time of the peripheral zone varies depending on the mobile station, the stop time T corresponding to the measurement capability of the mobile station can be included in the transmission stop request signal 321 and transmitted.

If there are many peripheral zones to be measured on the side of the mobile station 101, it takes time to measure the reception level.

503).

When the base station 402 detects the reception of the transmission stop request signal 521 from the mobile station 1 (S511), the base station 402 determines that the mobile station 1 is the mobile station 1 based on the identifier for identifying the contained mobile station, and the mobile station 1 The signal transmission to the destination is stopped for a predetermined time T (S512).
