Is estimated.

Then, the number of path changes Pc detected here is
, Sector change count Sc, and estimated moving speed Sp
Is recorded in an area of the database 18 corresponding to the current time measured by the clock unit 19.

The external input interface 15 is a keypad having, for example, a numeric keypad, an outgoing / incoming / outgoing key, a multi-function key, and the like, and accepts instructions and data input from a user.

The movement information setting section 16 receives movement information input by the user through the external input interface 15, records the received movement information in the database 18, and informs the user that movement information has been input by the user. Is notified to the database setting evaluation unit 17 described later.

The movement information includes a user state Sn (n = 0 to 2) indicating an action pattern of the user and time zone information t0 to tm (m is a Δ
t).

The user state Sn includes S0 indicating a state where the user is not moving at all due to sleep, S1 indicating a low-speed movement such as walking, and S indicating a state where the user is moving at high speed.
There are two.

The time zone information t0 to tm is information on the time zone at intervals of Δt. In the following, for the sake of simplicity of description, an example will be described in which Δt is one hour and one day is divided into 24 equal parts. That is, the time zone information is described as t0 to t23.

After receiving the notification from the movement information setting unit 16, the database setting evaluation unit 17 monitors the current time notified from the clock unit 19 described later, and sets the current time for a certain period tw.
Each time (for example, several days) elapses, time zone information t0
Based on the information (path change information Pc, sector change information Sc, and moving speed Sp) stored in the database 18 for each tm, the setting of the state S, the start interval T, and the number of detected paths Np in each time zone t0 to t23 is performed. Change the settings as appropriate.

The database 18 stores time zone information t0 to t
23 stores information R0 to R23 respectively corresponding to the information 23, and reads and outputs information requested from others,
It has a function of recording information input from another according to the current time measured by the clock unit 19.

The information R0 to R23 is transmitted to the state detector 14

c, the moving speed Sp, the user state Sn, the activation interval T, and the number of detected paths Np.

The clock section 19 has a clock function for measuring the current time.
And the timer expiration value determination unit 21 is notified. The number-of-detected-paths determination unit 20 stores the time zone information t0 to t in the database 18.
Among the information R0 to R23 stored in association with
The number of detected paths Np in the time zone information R corresponding to the current time notified from the clock unit 19 is read, and this value is set in the intermittent activation calculation processing unit 13.

The timer expiration value determination unit 21 is configured to output the information of the time zone corresponding to the current time notified from the clock unit 19 among the information R0 to R23 stored in the database 18 in association with the time zone information t0 to t23. The activation interval T in R is read, and this value is set in the activation control timer 11.

Next, operations related to the path search and the cell / sector search of the mobile radio terminal having the above configuration will be described. FIG. 2 shows a processing flow for explaining this operation.

First, in step 2a, as an initial setting, the user takes into account his / her own life rhythm and inputs time zone information t0 to t23 through the external input interface 15.
Each time, the user state Sn is input. The movement information input in this manner is received by the movement information setting unit 16, is recorded in the database 18, and proceeds to step 2b.

In step 2b, control is performed such that the path search and the cell / sector search are performed by an intermittent operation in accordance with the initially set movement information set in step 2a.

In this control, the detection path number determination unit 20
The current time notified from the clock unit 19 and the database 1
8 is monitored, and when it is detected that the time zone to which the current time belongs has been switched to the next time zone, the number of detected paths Np in the information R corresponding to the switched time zone is determined. The value is read out, and this value is set in the intermittent activation calculation processing unit 13.

In parallel with this, the timer expiration value determination unit 21
Monitors the current time notified from the clock unit 19 and the time zone information t0 to t23 stored in the database 18 in the same manner as the detected path number determination unit 20, and determines that the time zone to which the current time belongs is the next time zone. Is detected, the activation interval T in the information R corresponding to the switched time zone is read, and this value is set in the activation control timer 11.

On the other hand, the activation control timer 11 outputs an activation signal to the radio processing unit 12 for a predetermined time every time the activation interval T set by the timer expiration value determination unit 21 elapses. .

In the radio processing unit 12, the intermittent start-up operation processing unit 13 operates only while the start-up signal is input from the start-up control timer 11, and performs a path search and a cell / sector search during this operation. , The number of paths Np notified from the detected path number determination unit 20 is detected.

In parallel with the above operation, the state detection unit 14 detects the number of path changes Pc and the number of sector changes Sc detected by the intermittent activation calculation processing unit 13 and also performs fading of the received signal. The average moving speed Sp of the own terminal is estimated from the pitch. Then, the detected path change number Pc, the sector change number Sc, and the estimated moving speed Sp are recorded in the database 18.

The control operation based on the initial setting in step 2b is performed after the end of step 2a until the tw period elapses. That is, during the tw period, information on the number of path changes Pc, the number of sector changes Sc, and the traveling speed Sp for each of the user's time zones t0 to t23 is collected.

When the tw period elapses after the end of step 2a, the process shifts from step 2b to step 2c. In step 2c, as shown in FIG. 3, the database setting evaluator 17 determines based on the information (path change information Pc, sector change information Sc, movement speed Sp) accumulated in the database 18 for each of the time zone information t0 to t23. In each of the time periods t0 to t23, the state S, the start interval T, and the number of detected paths Np
Change the setting of to the appropriate setting.

In this changing process, the moving state of the user is determined from the path change information Pc, the sector change information Sc and the moving speed Sp for each of the time periods t0 to t23, and the state S and the start interval corresponding to the moving state are determined. T and the number of detection paths Np are obtained.

Then, this information is overwritten on the already recorded state S, start interval T and detected path number Np. When this process is performed for all the time zones t0 to t23, the process proceeds to step 2d.

In step 2d, according to the information R of the database 18 updated in step 2c, control is performed so that the path search and the cell / sector search are performed by an intermittent operation. The content of the control of each unit is the same as that described in the above step 2b, so that the description is omitted here.

When the tw period elapses after the end of step 2c, the process shifts from step 2d to step 2e. In step 2e, similarly to step 2c, as shown in FIG. 3, the database setting evaluation unit 17 stores information (path change information Pc, sector change information Sc) stored in the database 18 for each of the time zone information t0 to t23. Based on the moving speed Sp), the setting of the start interval T and the number of detected paths Np in each time zone t0 to t23 is changed to an appropriate setting.

When this process is performed for all the time zones t0 to t23, the subsequent processes are controlled so that the path search and the cell / sector search are performed by the intermittent operation as in step 2d. Thereafter, such a control operation is repeatedly executed.

As described above, in the mobile radio terminal having the above configuration, in the period tw after the input of the movement information by the user, the path search and the cell search are performed in accordance with the movement information.
The operation related to the sector search is intermittently controlled. Thereafter, the operation related to the path search and the cell / sector search is intermittently controlled based on the operation results collected during the period tw. I try to repeat every time.

Therefore, according to the mobile radio terminal having the above-described configuration, the intermittent control relating to the path search and the cell / sector search is performed according to the user's life pattern. Power consumption can be reduced well. Further, since the information on which the intermittent control is based is reviewed every period tw, even if the life pattern of the user changes, the intermittent control can be performed according to the change.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the detection path number determination unit 20 determines the number of paths to be detected based on the information detected by the state detection unit 14. However, instead of this, for example, the state detection unit In the early stage when sufficient information has not been obtained by 14, the number of paths to be detected may be determined based on the movement information input by the user. It goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0051]

As described above, according to the present invention, the intermittent cycle of each time zone is determined based on the movement information for each time zone input through the input means, and path detection is performed at this intermittent cycle. I have to.

Therefore, according to the present invention, the intermittent period of the corresponding time zone can be set by the user setting arbitrary movement information for each time zone through the input means, so that the user can set the intermittent cycle according to the life pattern of the user. A mobile wireless terminal that can operate intermittently and reduce power consumption can be provided.

Further, according to the present invention, for example, the change state of the reception timing of the main path and the moving speed are stored in the storage means for each time zone, and the intermittent status of each time zone is stored based on the information stored in the storage means. The period is determined, and path detection is performed at this intermittent period.

Therefore, according to the present invention, information according to the user's action pattern is stored in the storage means, and the intermittent period of each time zone is set based on this information.
It is possible to provide a mobile wireless terminal in which an intermittent operation according to a user's life pattern is performed and power consumption can be efficiently reduced.
