Method of distributing content data, communication system, and distribution device

摘要

The present invention enables provision of a service in which a distribution method of content is changed depending on a location of a mobile station. Specifically, if a user of mobile station MS is located in a country where the usage of content is not permitted, content server CS detains the content temporarily, and after confirming that the user has moved to a country where the usage of the content is permitted, sends the detained content to mobile station MS of the user. When detaining the content, content server CS checks whether an expected date of the user moving to a country where the usage of the content is permitted is within a distribution period of the content, and if so, detains the content.
