Satomi

Satomi
――What kind of response from users?
Mr. Uehara
――What kind of changes have been added from the initially released map?
Mr. Denzen<4月からは復旧の目処を追加しました。また、無料の充電サービスなどはアイコンで表示していますが、同じ場所に複数のサービスを展開している場合、アイコンが重なってしまいますので、重なって見づらくならないよう、少しずらして見えやすくなるよう工夫しています。

■ Flow from grasping the damage status and recovery
――How did the damage on the day change?Did you know the damage status of the equipment immediately in Tokyo?
Satomi
-The recovery area map seems to be characterized by the specific shown, rather than an administrative area such as municipalities or a simple paint.What is the recovery in the area of the stricken area?

Mr. Kiyomoto
--I see.For example, if a base station is stopped due to a power outage, what will happen until it is restored?
Mr. Kiyomoto
■ Indicates "where you can't use" and "scheduled recovery time"
――DOCOMO has been offering a “area map” that introduces places that can be used, but is that system used?
Mr. Uehara
―― For users, the information of “unusable areas” is easy to understand whether you can use it if you walk more than 1km.
Mr. Uehara
Satomi<3月までは「使えないエリア」を示す形でしたが、4月に入って復旧予定も追加しています。この復旧予定の時期を明示するという構想は最初からありました。具体的に時期を公表できるだけの精度になったことで追加したことになります。
―― At a conference on March 30, a large zone method was introduced as a restoration means.For users, it is still "useful", but from a mean perspective, it can be said that the large zone method, which has an increase in the number of people covered by one base station, has a difference in service quality.increase.The difference in quality is not reflected in the "restoration area map".
