Cellular telephone with automated redial functions

A method of processing a call in a system comprising a cellular telephone, comprising:

• executing a call origination for calling a destination telephone number in response to a request for said call origination;
• executing a call termination process and retrying said call origination upon occurrence of a failure in said call origination;
• stopping said retrying if a count of said call origination reaches a predetermined count value;
• and
• delaying said retrying while a received wave level is less than a predetermined level, wherein the delaying said retrying comprises deciding whether said received wave level is less than said predetermined level, relative to a reception condition of GPS (global positioning system).

A method of processing a call in a system comprising a cellular telephone, comprising:

• executing a call origination for calling a destination telephone number in response to a request for said call origination;
• executing a call termination process and retrying said call origination upon occurrence of a failure in said call origination;
• stopping said retrying if a count of said call origination reaches a predetermine count value;
• and
• delaying said retrying while a received wave level is less than a predetermined level, wherein the delaying said retrying comprise deciding whether said received wave level is less than said predetermined level, relative to information from a navigation system.

A cellular telephone apparatus capable of establishing and maintaining a call subject to a failure in call establishment, a busy state of a called party, or a communications channel disorder, the apparatus comprising:

• means for executing a call origination for a destination telephone number in response to a request for said call origination;
• means for automatically executing a call termination process in response to detection of a failure in said call origination;
• means for automatically retrying said call origination in response to said call termination;
• means for automatically delaying said retrying when a received wave level is less than a predetermined level;
• and
• means for automatically stopping said retrying if a count of said call origination reaches a predetermined count value.

A cellular telephone apparatus capable of establishing and maintaining a call subject to a failure in call establishment, a busy state of a called party, or a communications channel disorder, the apparatus comprising:

• means for responding to a request for a call origination for a destination telephone number and for executing said call origination;
• means for responding to a detection of a failure in said call origination and for executing a call termination process;
• means for responding to said call termination and for retrying said call origination;
• table means for associating each of prospective called parties with at least one telephone number;
• means, operative in the event that said failure is due to a busy state of a called telephone terminal identified by said destination telephone number, for executing a call origination for a substitution telephone number, which is one of said at least one telephone number associated with a called party identified by said destination telephone number in said table means, said at east one number being different from a last called telephone number;
• and
• means for responding to a detection of disconnection of a current call after said call origination, wherein the disconnection is caused not by a user but by a channel disorder;
• means for executing a call termination process;
• and
• means for originating a new call for said destination telephone number of said current call.

A portable system including a cellular telephone mean capable of establishing and maintaining a call subject to a failure in call establishment, a busy state of a called party, or a communications channel disorder, the cellular telephone mean comprising:

• means for executing a call origination for a destination telephone number in response to a request for said call origination;
• means for executing a call termination process in response to a detection of a failure in said call origination;
• means for retrying said call origination in response to said call termination;
• means for stopping said retrying if a count of said call origination reaches a predetermined count value;
• and
• means for responding to a detection of disconnection of a current call after said call origination, wherein the disconnection is caused not by a user but by a channel disorder;
• means for executing a call termination process;
• and
• means for originating a new call for said destination telephone number of said current call.
