Docomo 全国 5G SA 服务中断接近三小时,尚无恢复时间预估

截至日本标准时间下午 1:30,独立组网 5G 用户的通话、数据和短信服务仍不稳定。紧急呼叫不受影响,切换到 4G 可能会有所帮助。

Docomo 手机可能会显示“无服务”,但紧急呼叫不受影响。这是 2026 年 11 月 11 日波及日本各地的一次服务中断中一个重要区别:Docomo 独立组网 5G 服务的用户难以使用普通通话、移动互联网和短信,但问题并未影响所有 Docomo 用户。⁠44

日本标准时间下午 1:30,距离上午 10:34 服务中断开始已过去两小时 56 分钟,NTT Docomo 仍在努力恢复服务。该运营商尚未查明原因,也未提供预计恢复时间。对于受影响的用户,该公司给出的即时建议是尝试切换至 4G 连接。⁠44

这项建议的适用范围很重要。切换网络可能让用户重新使用通话、短信和数据服务,但这不意味着 Docomo 已修复底层故障。从故障发生到下午通报之间的 176 分钟,反映的是截至该节点事故持续未解决的时长,而不是事故的最终持续时间,也不是每位用户的断网时长。⁠44

全国范围不等于影响所有用户

Docomo 指出,受影响群体是订购其 5G SA 选项的用户。该公司明确排除了未订购该选项的其他 5G 用户、使用 4G 的用户,以及移动虚拟网络运营商——即使用 Docomo 网络的其他服务提供商。公司没有给出受影响用户总数。“全国范围”描述的是服务中断的地理覆盖范围,而非失去服务的人数。⁠44

SA 是“独立组网”的缩写。Docomo 对该服务的说明称,它使用专用 5G 设备;普通的非独立组网 5G(即 NSA)则结合使用 5G 和 4G 设备。独立组网服务是一种单独的选项:仅仅拥有一部支持 5G 的手机,并不意味着某人属于受影响用户群体。⁠39

这一区别有助于解释为何同一运营商的用户在事故期间可能有不同体验。不过,它只能说明哪种服务受到影响,不能说明哪个组件发生了故障。Docomo 在第四份事故通报中仍将原因列为调查中。⁠44

对受影响的用户而言,服务中断影响了三种基本的联络方式:通话、发送短信和上网。运营商警告称,有些手机可能会显示无服务提示。但该公司描述的是这些功能难以使用,并未认定所有受影响的手机都完全失去了全部三项功能。同一份通报明确表示,紧急呼叫不受影响。⁠44

受影响用户可以尝试什么

Docomo 的指示有明确的顺序:先在手机的网络设置中选择 4G,然后重启手机,或打开再关闭飞行模式。选择 4G 后,重启手机和切换飞行模式是两种可选操作;指示并未要求两项都做。该公司称,按此步骤操作可能会恢复语音通话、移动数据和短信的使用。⁠44

“可能”一词在这里确有分量。这只是绕开受影响的独立组网服务的一种可能方式,并非保证有效的解决办法。恢复工作仍在进行时,重新通过 4G 连接的用户可能会重新获得访问权限。反过来,尝试未成功,也不能据此对网络问题的原因作出新的判断。这项建议是针对受影响用户的,并不意味着服务正常的用户需要更改设置。⁠44

如需帮助,Docomo 列出的联系方式包括用其手机拨打 113,以及用其他电话拨打 0120-800-000。该公司第三份事故通报还列出了 Docomo 帮助聊天机器人,可通过智能手机或电脑使用。运营商称,这些支持渠道全年每天 24 小时开放。但这并不保证受影响的移动连接能够成功接通这些渠道。⁠29

11 月 11 日事故进展节点

  1. 11 月 11 日,日本标准时间上午 10:34

    Docomo 称,服务中断开始影响全国 5G SA 用户的普通语音通话、移动数据和短信。

    44
  2. 11 月 11 日,日本标准时间中午 12:30

    第三份事故通报称情况与第二份通报相比没有变化,并表示恢复工作仍在继续。

    29
  3. 11 月 11 日,日本标准时间下午 1:30

    第四份通报再次称情况没有变化,服务仍受影响,原因仍在调查中。

    44

一再发布的通报记录的是服务持续受影响,而非恢复情况。在最新经核实的节点——日本标准时间下午 1:30,Docomo 既未提供恢复时间预估,也未公布受影响用户人数。因此,这些通报能够准确说明受影响的服务范围和临时替代方案,却不足以支持有关多少人失去连接或正常服务何时恢复的说法。⁠44

对用户而言,有两种不同的进展值得关注:现在能否通过 4G 重新获得连接,以及 Docomo 是否确认独立组网服务本身已恢复。通过前者重新接入很有帮助,但不能证明后者已经发生。

播出原貌
  1. Docomo's standalone 5G customers face unreliable calls, texts and mobile internet across Japan.
  2. Emergency calls are unaffected, but restoration work is still unfinished nearly three hours into the disruption. Affected customers may be able to reconnect by switching their phones to 4G.
  3. When will normal service return, and what can customers do while repairs continue?
  4. The disruption reaches across Japan, within Docomo's standalone 5G subscriber group. Docomo hasn't given an affected-customer total. The nationwide footprint describes where the problems occur, while the service option defines which customers are affected.
  5. Voice calls, mobile data and SMS text messages are all difficult to use for affected subscribers. That leaves people struggling with several basic ways of reaching someone, even as the carrier's emergency-calling service remains outside the disruption.
  6. Docomo's disruption began at 10:34 a.m. Japan time on November 11. By 12:30 p.m., repairs were still under way. At 1:30 p.m., the company again said nothing had changed and restoration work continued.
  7. That puts the disruption at 176 minutes, or two hours and 56 minutes, when Docomo issued that status update. The interval runs from the start of the incident to a point when service was still impaired. Individual customers' experiences can vary.
  8. Standalone 5G uses dedicated 5G equipment. Ordinary non-standalone 5G combines 5G and 4G equipment. Docomo offers standalone service as a distinct option, so having a 5G-capable phone alone doesn't put someone in the affected subscriber group.
  9. The service boundary also explains why people using the same carrier can have different experiences during this incident. Docomo identifies subscribers to its standalone option, known as 5G SA, as the group facing problems.
  10. Other 5G subscribers and people using 4G are unaffected, Docomo says. The company also excludes mobile virtual network operators, meaning other providers using its network. And it explicitly says emergency calls are unaffected.
  11. Some affected phones may display no service. That warning can be alarming, but Docomo says emergency calling is unaffected. Customers can experience difficulty with calls, data or texts without every affected phone completely losing all three functions.
  12. Docomo advises affected customers to select 4G in their phone's network settings first. Then either restart the phone or turn airplane mode on and off. Those are alternative actions after selecting 4G. The company says this may make calls, data and SMS usable again.
  13. The procedure may help, but it isn't guaranteed to work. A customer reconnecting through 4G can regain access while Docomo continues repairing the standalone service. The advice is aimed at affected subscribers; unaffected customers don't need to change their settings because of this incident.
  14. Docomo's support line is 113 from its mobiles, or 0120-800-000 from other phones. Its assistance chatbot is available on a smartphone or computer. The company lists these support channels as open around the clock, every day of the year.
  15. At the 1:30 p.m. status update, Docomo was still investigating the cause and working to restore normal service. The company hadn't given an estimated recovery time.
