1. A mobile navigation device comprising:
- a navigation control module that transmits a destination and a starting point via a network and/or a present position fixed via a GPS means, to an information distribution computer system, together with a request for routing guidance, and performs routing guidance on the basis of information delivered by the information distribution computer system;
a telephone communication control module for effecting telephone communication with other mobile telephones; and
an operation control module for controlling the navigation control and telephone communication control modules;
and wherein;
upon detecting a particular event while the navigation control module is in operation, the operation control module sends a suspension command to the navigation control module, thereby suspending operation of the same; and
upon detecting termination of the particular event, the operation control module sends a resumption command to the navigation control module to resume operation.

Abstract
A navigation device having a function of dealing with a case where a navigation function cannot be executed at the same time as another function, such as a telephone function, because of constraints of the processing capability of a CPU or the memory capacity in a mobile telephone. A navigation device (10), which uses a mobile telephone having GPS means, comprises a navigation control module (123); a telephone communication control module (122) for telephone communicating with another mobile terminal device; and an operation control module (OS) (121) for controlling those modules. When detecting a particular event during operation of the navigation control module, the OS sends a suspension command to the navigation control module, thereby suspending the navigation control module. When detecting a termination of the particular event, the OS sends a resumption command to the navigation control module, thereby resuming the navigation control module.

11. A control method for a mobile navigation device comprising:
-
a navigation control module that transmits a destination and a starting point via a network and/or a present position fixed via a GPS means, to an information distribution computer system, together with a request for routing guidance, and performs routing guidance on the basis of information delivered by the information distribution computer system;
a telephone communication control module for effecting telephone communication with other mobile telephones; and
an operation control module for controlling the navigation control and telephone communication control modules;
and being a control method comprising;
a step wherein, upon detecting a particular event while the navigation control module is in operation, the operation control module sends a suspension command to the navigation control module, thereby suspending operation of the same; and
a step wherein, upon detecting termination of the particular event, the operation control module sends a resumption command to the navigation control module to resume operation. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A control program for a computer device comprising:
-
a navigation function wherein the navigation control module transmits a destination and a starting point via a network and/or a present position fixed via a GPS means, to an information distribution computer system, together with a request for routing guidance, and performs routing guidance on the basis of information delivered by the information distribution computer system;
a telephone communication control function for effecting telephone communication with other mobile telephones; and
an operation control function, being a control program that causes such computer device to realize the function of turning off and on the GPS means, using the telephone communication control as trigger. - View Dependent Claims (19, 20, 21, 22)
