Abstract

A mobile unit 10 is provided with a called party number acquiring unit 102 for acquiring a called party number corresponding to a call origination command entered by a user, a number checking unit 103 for checking the called party number acquired by the called party number acquiring unit 102, against every origination-restricted number stored in an origination-restricted number storing unit 112, and an origination restricting unit 104 for restricting origination of a call on the basis of the result of the checking by the number checking unit 103.

Claims

1. A mobile unit comprising:

called party number storing means for storing a called party number;

calling party number acquiring means for acquiring a calling party number corresponding to an incoming call;

ringing time measuring means for measuring a ringing time of the incoming call;

number checking means for checking a calling party number acquired by the calling party number acquiring means and a called party number stored in the called party number storing means; and

storage restricting means for storing a called party number corresponding to the incoming call in a calling party number storing means when a calling party number acquired by the calling party number acquiring a means corresponds to a called party number stored in the called party number storing means as a result of checking by the number checking means, for storing a calling party number corresponding to the incoming call in calling party number storing means when a calling party number acquired by the calling party number acquiring means does not correspond to a called party number stored in the called party number storing means as a result of checking by the number checking means and the ringing time measured by the ringing time measuring means is longer than a predetermined time as a result of checking by the number checking means, and for avoiding storing the calling party number corresponding to the incoming call in the calling party number storing means when a calling party number acquired by the calling party number acquiring means does not correspond to a called party number stored in the called party number storing means as a result of checking by the number checking means and the ringing time measured by the ringing time measuring means is not longer than the predetermined time.

2. A call termination controlling method comprising:

a calling party number acquiring step wherein calling party number acquiring means acquires a calling party number corresponding to an incoming call;

a ringing time measuring step wherein ringing time measuring means measures a ringing time of the incoming call;

a number checking step wherein number checking means checks a calling party number acquired by the calling party number acquiring means and a called party number stored in a called party number storing means; and

a storage restricting step wherein storage restricting means stores a called party number corresponding to the incoming call in calling party number storing means when a calling party number acquired by the calling party number acquiring means corresponds to a called party number stored in the called party number storing means as a result of checking by the number checking means, stores a calling party number corresponding to the incoming call in the calling party number storing means when a calling party number acquired by the calling party number acquiring means does not correspond to a called party number stored in the called party number storing means as a result of checking by the number checking means the ringing time measured by the ringing time measuring means is longer than a predetermined time as a result of checking by the number checking means, and avoids storing the calling party number corresponding to the incoming call in the calling party number storing means when a calling party number acquired by the calling party number acquiring means does not correspond to a called party number stored in the called party number storing means as a result of checking by the number checking means and the ringing time measured by the ringing time measuring means is not longer than the predetermined time.

3. A mobile unit comprising:

a first memory configured to store a called party number;

calling party number acquiring unit configured to acquire a calling party number corresponding to an incoming call;

ringing time measuring unit configured to measure a ringing time of the incoming call;

number checking unit configured to check a calling party number acquired by the calling party number acquiring unit and a called party number stored in the first memory; and

storage restricting unit configured to store a called party number corresponding to the incoming call in a second memory when a calling party number acquired by the calling party number acquiring unit corresponds to a called party number stored in the first memory as a result of checking by the number checking unit, store a calling party number corresponding to the incoming call in the second memory when a calling party number acquired by the calling party number acquiring unit does not correspond to a called party number stored in the first memory as a result of checking by the number checking unit and the ringing time measured by the ringing time measuring unit is longer than a predetermined time as a result of checking by the number checking unit, and not store the calling party number corresponding to the incoming call in the second memory when a calling party number acquired by the calling party number acquiring unit does not correspond to a called party number stored in the first memory as a result of checking by the number checking unit and the ringing time measured by the ringing time measuring unit is not longer than the predetermined time.
