System and method for recovering a communications station in sleep mode

A method for communications station sleep mode recovery, the method comprising:

• configuring, by a server, a first access point (AP) to communicate a secret information to a communications station, the secret information for use by the first AP to generate a first wakeup identifier (WUID) for waking up the communications station;
• detecting, by the server, that the first AP is unable to wake up the communications station;
• and
• in response to the detecting, configuring, by the server, a second AP with the secret information to wake up the communications station, the secret information for use by the second AP to generate a second WUID for waking up the communications station, the second WUID being different from the first WUID.

A communications station, comprising:

• a non-transitory memory storage comprising instructions;
• and
• one or more processors in communication with the non-transitory memory storage, wherein the one or more processors execute the instructions to configure the communications station to:
• receive, from a first access point (AP), information conveying a first wakeup identifier (WUID) of the communications station, the first WUID for receipt in a first wakeup packet (WUP) from the first AP,
• obtain information conveying a second WUID of the communications station, the second WUID for receipt in a second WUP from a second AP, the first and second APs being non-collocated,
• enter a sleep mode in which a radio communications module (RCM) of the communications station is in a reduced power state and in which a wakeup receiver of the communications station is in an active state,
• detect one of the first WUP including the first WUID from the first AP or the second WUP including the second WUID from the second AP, while the RCM is in the reduced power state, and
• in response to detecting the first or second WUP while the RCM is in the reduced power state, transition the RCM from the reduced power state to the active state.

A server comprising:

• a non-transitory memory storage comprising instructions;
• and
• one or more processors in communication with the non-transitory memory storage, wherein the one or more processors execute the instructions to configure the server to:
• configure a first access point (AP) to communicate a secret information to a communications station, the secret information for use by the first AP to generate a first wakeup identifier (WUID) for waking up the communications station,
• detect that the first AP is unable to wake up the communications station, and
• in response to detecting that the first AP is unable to wake the communications station, configure a second AP with the secret information to wake up the communications station, the secret information for use by the second AP to generate a second WUID for waking up the communications station, wherein the second WUID is different from the first WUID.
