Competitive management system and method for external input/output devices and recording medium recording program
View Patent ↗The present invention provides a competitive management system for external input/output devices in which there is no need for each service to make the competitive management for external input/output devices. The competitive management system for external input/output devices comprises a transmission line management module for making the competitive management for external input/output devices with each service. The transmission line management module has a table indicating the support correspondence between external input/output device and service, and makes the competitive management by referring to this table. Accordingly, there is no need for each service to make the competitive management for external input/output devices.
1. A competitive management system for external input/output devices used in conjunction with a portable terminal comprising:
a plurality of external input/output devices;
one or more services usable with said external input/output devices; and
managing means for managing together said one or more services and said plurality of external input/output devices not to use the same service at the same time by referring to a management table.
2. The competitive management system for according to claim 1 , wherein said management table contains service state information indicating whether or not the status of each service is idle and external input/output device information indicating by which external input/output device each service is used.
3. The competitive management system according to claim 2 , further comprising
an application which uses said one or more services, wherein said managing means refers to said management table when receiving a waiting request or a connection request from said application.
4. The competitive management system according to claim 2 , wherein said managing means refers to said management table when receiving a connection request to a service from one of said plurality of external input/output devices.
5. The competitive management system according to claim 1 , wherein said managing means consists of a single management module.
6. A competitive management method for a system comprising a plurality of external input/output devices and one or more services usable with said external input/output devices, comprising:
managing together said one or more services and said plurality of external input/output devices such that no more than one of said plurality of external input/output devices uses the same service at the same time by referring to a management table.
7. The competitive management method according to claim 6 , wherein said management table contains service state information indicating whether or not the status of each service is idle and the-external input/output device information indicating by which external input/output device each service is used.
8. The competitive management method according to claim 7 , further comprising referring to said management table when receiving a waiting request or a connection request from an application using one of said one or more services.
9. The competitive management method according to claim further comprising:
referring to said management table when receiving a connection request to a service from one of said plurality of external input/output devices.
10. The competitive management method according to claim 6 , wherein the step of managing is performed by a single management module.
11. A program product for a competitive management system for external input/output devices used in conjunction with a portable terminal, comprising:
a comnuter readable medium; and
instructions embodied on the comnuter readable medium for enablina the portable terminal to perform operations including:
managing together said one or more services and said plurality of external input/output devices such that no more than one of the plurality of external input/output devices uses use the same service at the same time, by referring to a management table.
12. The program product according to claim 11 , wherein the management table contains service state information indicating whether or not the status of each service is idle and external input/output device information indicating by which external input/output device each service is used.
13. The program product according to claim 12 , wherein the instructions embodied on the computer readable medium enable the portable terminal to perform operations which further include:
referring to said management table when receiving a waiting request or a connection request from an application using one of the one or more services.
14. The program product according to claim 12 , wherein the instructions embodied on the computer readable medium enable the portable terminal to perform operations which further include:
referring to said management table when receiving a connection request to a service from one of the plurality of external input/output devices.
15. The program product according to claim 11 , wherein the step of managing is performed by a single management module.
