Third party Push platform providers like Mozilla's FirefoxOS Push server should sign an agreement with mobile operators to have access to the wake up public APIs.
These third party clients will benefit from the battery savings of their devices and reduced network consumption on any cellular network.
After signing the agreement, the Operator will deliver a signed certificate (self-signed or verified by third parties CAs) which will identify in a unique way the wakeup platform users.
This certificate MUST be used to Authenticate and Authorize access to the WakeUp platform.
