Name changing method, information processing apparatus and network system
The present invention is a method for changing a device identification name of an information processing apparatus to which the device identification name is added for identification by a user. First, a device identification name of other information processing apparatus connected to a same network is obtained. Next, the device identification name of the other information processing apparatus and the device identification name of the information processing apparatus are compared. Further, when the device identification name of the other information processing apparatus and the device identification name of the information processing apparatus are the same, it is judged, according to a predetermined rule set beforehand, whether or not to change the device identification name of the information processing apparatus. Then, when it is judged to change the device identification name of the information processing apparatus, the device identification name of the information processing apparatus is changed.
1. A method of operating a first information processing apparatus to which a device identification name is added for identification by a user, comprising:
an obtaining step of obtaining a device identification name of a second information processing apparatus connected to a same network as the first information processing apparatus;
a comparing step of comparing the device identification name of the second information processing apparatus and the device identification name of the first information processing apparatus;
a judging step of judging, via a judging section of the first information processing apparatus, according to a predetermined rule set beforehand, whether or not to change the device identification name of the first information processing apparatus when the device identification name of the second information processing apparatus and the device identification name of the first information processing apparatus are the same; and
a changing step of changing the device identification name of the first information processing apparatus when it is judged to change the device identification name of the first information processing apparatus in the judging step,
wherein the judging step comprises a lock judging step of judging, via the judging section, based on lock information indicating whether it is possible to change the device identification name of the first information processing apparatus, whether or not to change the device identification name of the first information processing apparatus, wherein the lock information is based on a determination of whether the second information processing apparatus has recognized the first information processing apparatus, and wherein the judging step further comprises a time stamp judging step of judging whether or not to change the device identification name of the first information processing apparatus based on access history indicating status of access from an information processing apparatus connected to the same network.
2. The method according to claim 1 , wherein the time stamp judging step
compares a time stamp of the first information processing apparatus and a time stamp of the second information processing apparatus, and
changes the device identification name of the first information processing apparatus when the time stamp of the first information processing apparatus is older than that of the second information processing apparatus.
3. The method according to claim 1 , wherein the judging step comprises:
a unique identification information judging step that judges whether or not to change the device identification name of the first information processing apparatus based on a comparison between identification information unique to the first information processing apparatus and identification information unique to the second information processing apparatus.
4. A first information processing apparatus to which a device identification name is added for identification by a user, comprising:
an obtaining section for obtaining a device identification name of a second information processing apparatus connected to the same network as the first information processing apparatus;
a comparing section for comparing the device identification name of the second information processing apparatus and the device identification name of the first information processing apparatus;
a judging section for judging, according to a predetermined rule set beforehand, whether or not to change the device identification name of the first information processing apparatus when the device identification name of the second information processing apparatus and the device identification name of the first information processing apparatus are the same; and
a changing section for changing the device identification name of the first information processing apparatus when it is judged to change the device identification name of the first information processing apparatus,
wherein the judging section comprises a lock judging section for judging, based on lock information indicating whether it is possible to change the device identification name of the first information processing apparatus, whether or not to change the device identification name of the first information processing apparatus, wherein the lock information is based on a determination of whether the second information processing apparatus has recognized the first information processing apparatus, and wherein the judging step further comprises a time stamp judging step of judging whether or not to change the device identification name of the first information processing apparatus based on access history indicating status of access from an information processing apparatus connected to the same network.
5. A network system in which a plurality of information processing apparatuses to which device identification names are added for identification by a user are connected with each other via the network, wherein
a first information processing apparatus is configured to:
obtain a device identification name of a second information processing apparatus connected to the same network,
compare the device identification name of the second information processing apparatus and the device identification name of the first information processing apparatus,
judge, according to a predetermined rule set beforehand, whether or not to change the device identification name of the first information processing apparatus when the device identification name of the second information processing apparatus and the device identification name of the first information processing apparatus are the same; and
change the device identification name of the first information processing apparatus when it is judged to change the device identification name of the first information processing apparatus,
wherein the judging comprises judging, based on lock information indicating whether it is possible to change the device identification name of the first information processing apparatus, whether or not to change the device identification name of the first information processing apparatus, wherein the lock information is based on a determination of whether the second information processing apparatus has recognized the first information processing apparatus, and wherein the judging step further comprises a time stamp judging step of judging whether or not to change the device identification name of the first information processing apparatus based on access history indicating status of access from an information processing apparatus connected to the same network.
