Abstract: In a CP server, when a copyright determination unit determines that requested content is copyrighted content, a set up unit sets up a copyrighted content public URL comprising information that can specify a memory region where copyrighted content is stored, and corresponding to a content delivery request by a cellular phone, a transmission unit transmits the copyrighted content public URL together with the copyrighted content, to the cellular phone. Then, a cellular phone acquires the copyrighted content public URL together with the copyrighted content, and attaches the copyrighted content public URL to an electronic mail message which is transmitted to another cellular phone. The other cellular phone can use the received copyrighted content public URL to request the CP server to deliver the copyrighted content.

Abstract: Direct content redistribution between users belonging to the same community is enabled. A portable telephone set issues a request to a community management server to register portable telephone sets belonging to a community, in association with the community, and the community management server performs community registration. The portable telephone sets issue requests to the community management server for permission to redistribute content which has been distributed from a CP server, and when the redistribution permission request is for registered portable telephone sets belonging to the same community, the community management server grants permission for the redistribution. By this means, content redistribution can be performed directly between users belonging to the same community, without the intervention of the CP server.

Abstract: A mobile phone stores a plurality of profile data, each including a portal URL. A user of the mobile phone selects for use data of a profile including the portal URL. When a Java-AP running on the mobile phone transmits to JAM an instruction for a communication, JAM stores the domain name of the portal URL included in the selected profile data as information about the inhibited destination of a communication performed by the Java-AP. JAM restricts communications performed by a Java-AP on the basis of the information about the inhibited destination stored by JAM. Thus, communications from a Java-AP running on the mobile phone to the server apparatus assigned with the domain name of the portal URL may be inhibited by selection of profile data including a portal URL.
