Coordination operation method and mobile communication terminal
A mobile communication terminal having a structure including a host section and an engine section is built compactly. —As a request for using a host-connecting device is received from an engine section 40 , a host section 30 makes a judgment of whether or not a current state of an engine processor of the engine section 40 is an engine-mode state of controlling actively an operation of an engine-connecting device connected to the engine processor of the engine section 40 , and the engine-mode state is estimated to be continued. Further, when a result of the judgment is affirmative, the host section 30 operates a host-connecting section, according to an operation mode specified by operation mode parameters. As a result, in a mode in which a request is made by an application executed by the engine processor, a specific host-connecting device which the application has desired to use is operated.
1. A coordination method which is a method of operating by coordination between a host section which performs a processing associated with a communication with an outside, and an engine section which executes a predetermined function under a management of the host section, in a mobile communication terminal, comprising steps of:
making request for using specific host connecting device, at which a request for using a specific host connecting device from among host connecting devices which are connected to a host processor of the host section is sent from the engine section to the host section;
judging operation mode at which the host section which has received the request for using the specific host connecting device makes a judgment of whether or not an engine processor of the engine section is in an engine-mode state of controlling actively an operation of at least one engine connecting device which is connected to the engine processor of the engine section, and the engine-mode state is estimated to be continued; and
performing specified operation of engine at which, when a judgment result at the step of judging operation mode is affirmative, the host processor operates the specific host connecting device.
2. The coordination method according to claim 1 , wherein
when the judgment result at the step of judging operation mode is negative, the host section ignores the request for using the specific host connecting device.
3. The coordination method according to claim 1 , wherein
the specific host connecting device is a no-response device of a type in which, after an operation command is received from the host processor, a response is not sent back to the host processor.
4. A mobile communication terminal comprising:
a host section which comprises a host processor, and performs a processing associated with a communication with an outside;
at least one host connecting device which is connected to the host processor;
an engine section which comprises an engine processor, and performs a predetermined function operation under a management of the host section; and
at least one engine connecting device which is connected to the engine processor, wherein
the host section comprises,
a host connecting device controlling means which controls an operation of the host connecting device,
an operation mode judging means which makes a judgment of whether or not the engine processor of the engine section is in an engine-mode state of controlling actively an operation of the engine connecting device, and the engine-mode state is estimated to be continued, and
a means for giving command for use of specific host device which, when a judgment result by the operation mode judging means is affirmative, when a request for using a specific host connecting device from among the host connecting devices, notified from the engine section is received, gives a command for operating the specific host connecting device, to the host connecting device controlling means, and
the engine section comprises a means for making request for using device for specific host which sends the request for using the specific host connecting device to the host section.
5. The mobile communication terminal according to claim 4 , wherein
the specific host connecting device is a no-response device of a type in which, after an operation command is received from the host processor, a response is not sent back to the host processor.
6. The mobile communication terminal according to claim 5 , wherein
the specific host connecting device is a device selected from a group including a vibrator, a light emitting diode, and a back light of a liquid crystal display apparatus in a case in which a liquid crystal display device section of the liquid crystal display apparatus is included in the engine connecting device.
7. The mobile communication terminal according to claim 4 , wherein
the host section further comprises a wireless communication section which is connected to the host processor, and performs a wireless communication with a base station of a mobile communication network.
