However, the problem that only the software that can be operated by the mobile terminal device alone can be solved by distributed processing. However, for example, in the X server / client system of XFree86, processing depending on the function of the mobile terminal device is not covered. End up.

Further, in the invention described in Patent Document 2, a method is shown in which distributed processing is performed by a plurality of portable terminal devices and management / integration is performed by a server. However, the invention described in Patent Document 2 has a problem that a communication load due to the degree of processing dispersion and a bottleneck due to a difference in processing capability between terminals exist.
Further, in the invention described in Patent Document 3, service providing software is divided into a plurality of parts, and distributed processing is performed between the base station and the mobile phone in accordance with the mobile phone model. However, since the invention described in Patent Document 3 only considers distributed processing corresponding to the model of the mobile phone, the operation status of the mobile phone changes when the communication status changes or the like. There is a problem that it is difficult to carry out properly.
