雨果巴拉原文：
- The primary identifiers used to route messages are the sender and receiver s phone numbers. IMEI and IMSI information is also used to keep track of a device's online status.
- When a user sends a text message, if there is an Internet connection available, the Cloud Messaging system will attempt to route the message via IP. If the receiver is offline (i.e. not immediately reachable via IP), the system falls back to sending a normal SMS message from the sender s device.
- When a MIUI user opens a text message or a phonebook contact, or creates a new contact, the device connects to the Cloud Messaging servers, forwards the phone number of that contact and requests the online status of the corresponding user, which is indicated by a blue icon when that user is online or gray icon if that user is offline (or is not a Cloud Messaging user). This allows the sender to immediately know whether they can text that user without incurring SMS costs.
- In any of these flows, the receiver s phone number is only used to look up online status and to route messages. No phonebook contact details or social graph information (i.e. the mapping between contacts) is stored on Cloud Messaging servers, and message content (in encrypted form) is not kept for longer than necessary to ensure immediate delivery to the receiver.
- The OTA system update made available today (Aug 10th) adds an extra layer of security by encrypting phone numbers whenever they are sent to Cloud Messaging servers.
- We will continue to make changes and improvements to this architecture as needed over time.
