Estimating the term…
A cellular telephone apparatus capable of establishing and maintaining a call even in case of a failure in call establishment or a call due to a busy state of a called party or a communications channel disorder such as congestion or received wave level shortage. In response to a request for a call origination for a destination telephone number, a call is originated for the destination telephone number. In case of a failure in the call origination, a call termination process is executed and then the call origination is retried. Once a call is established after the call origination, in response to a detection of disconnection of the call caused not by a user but by a channel disorder, a call termination process executed. A call is originated for the same telephone number as a destination telephone number of the disconnected call. In an embodiment, the retrying is put off while a received wave level is less than a predetermined level. If a count of said call origination reaches a predetermined count value, then the retrying is stopped.
