2. Description of the Related Art In recent years, the use of the Internet has advanced, and Java (registered trademark), which is a network-oriented programming language, has become widespread. Along with this, there is an increasing number of processes for downloading software from a center server to a local computer or server via a wide area network such as the Internet. Moreover, recently, there is a need for a mechanism for downloading software to a computer having a relatively small memory capacity such as an embedded server.

Further, in an embedded server having a small capacity of an auxiliary storage device such as a memory or a disk, it may not be possible to keep all the applications in the memory at all times. Therefore, it is necessary to have a function of downloading software as needed and deleting it when it is no longer needed. The remote software management function as described above includes, for example, OSGi (Open Gateway).
O defined by the Service Initiative
There is a standard such as SG (Open Gateway Service).

Further, as disclosed in, for example, Japanese Patent Application Laid-Open No. 11-59668, ITU-T recommendation M.M. A system based on the manager / agent model defined by 3010 and having a mechanism for downloading software described in Java (registered trademark) is also proposed. Using these methods, we configure a home network centered on an embedded gateway server that can control home appliances and information terminals in each home, and provide software that controls home appliances and mediates between information terminals and the Internet. Systems for providing services by downloading and executing the programs or controlling those software from the outside are being realized.

Although the conventional gateway server management system is controlled as described above, when a plurality of service providers provide services via this built-in gateway server, the service is provided between the providers. Conflict occurs. Furthermore, the abnormality detection of each service agent must be implemented responsibly for each service provider.

Further, the service provider delivers the service agent itself which realizes the service, requests the delivered service agent, monitors the service agent, promptly recovers or deletes the event when an abnormality occurs, and receives the service from the gateway server. The response process for the request must be executed.

Further, when providing services over a wide area, the service provider needs to target gateway servers of tens to millions of households. When managing such a gateway server, there is a problem that the service provider itself causes a bottleneck in service provision.
