Abstract

Abstract There is provided a call re-connection system for use in mobile communication which is applicable to portable telephones and automobile telephones. In the call re-connection system, a call is automatically re-connected after speech communication is disconnected due to radio channel abnormality. A mobile station has a storage means for storing a telephone number of a calling party which is contained in a call connection signal, a detection means for detecting restoration of a radio channel to a normal state and an outgoing call means for generating an outgoing call on the basis of the telephone number of the calling party. A call is reconnected on the basis of the telephone number of the calling party which is stored in the storage means when restoration of the radio channel is detected after the speech communication is disconnected due to abnormality of the radio channel.

Claims Analysis

Total Claims: 5

Claim 1

Independent Claim 117 words

A call reconnection system in mobile communication operable when communication between a mobile station and a further station is terminated when abnormality is detected in a radio channel during the communication, said mobile station comprising: storage means for storing a telephone number of the further station; detection means for detecting restoration of a radio channel to a normal state; and outgoing call means for generating an outgoing call to the telephone number of the further station, wherein when said detection means detects restoration of a normal radio channel after communication is terminated because of abnormality in the radio channel, said outgoing call means causes said mobile station to generate automatically an outgoing call to said further station.

Claim 2

Dependent Claim 154 words

A call re-connection system in mobile communication in which communication between a calling station and a mobile station, which is started by an outgoing call from said calling station to said mobile station through a base station, is terminated when abnormality is detected in a radio channel during the communication, said mobile station comprising: storage means for storing a telephone number of a calling party which is included in a call connection signal; detection means for detecting restoration of a radio channel to a normal state; and outgoing call means for generating an outgoing call on the basis of the telephone number of the calling party which is stored in said storage means, wherein when said detection means detects restoration of a normal radio channel after communication is terminated because of abnormality in the radio channel, said outgoing call means causes said mobile station to automatically generate an outgoing call to said calling station.

Claim 3

Dependent Claim 25 words

A system according to Claim 2, wherein said mobile station and said base station further comprise detection means for detecting abnormality in a radio channel.

Claim 4
