System and method for managing data to be pushed to a wireless device when the device may be outside of a coverage range

A push proxy server for pushing data to a wireless device having a coverage state of online or offline, the push proxy server comprising:

• a coverage state detector for determining the coverage state of the wireless device based on a delivery status of a push request, the coverage state determination further based on a wireless device heartbeat message, to detect a device online to offline transition initiated due to a random network transport error, whenever the delivery status of the push request is indicated as undelivered;
• memory for storing a coverage state indicator for indicating the coverage state of the wireless device;
• a data store for storing the data to be pushed to the wireless device when the coverage state indicator indicates the wireless device is offline;
• a transceiver for transmitting the data to the wireless device when the coverage state indicator indicates the wireless device is online;
• and a waste manager for deleting stale data from the data store in accordance with an overwrite field of a header of the push data in the data store, the overwrite field indicating that stale data is to be deleted upon receipt of updated data.

A method for pushing data from a push initiator to a wireless device having a coverage state of online or offline, method comprising the steps of:

• determining, at a push proxy server, the coverage state of the wireless device based on the delivery status of a push request, the coverage state determination further based on a wireless device heartbeat message to detect a device online to offline transition initiated due to a random network transport error, whenever the delivery status of the push request is indicated as undelivered;
• storing in memory a coverage state indicator for indicating the coverage state of the wireless device;
• storing in memory the data to be pushed to the wireless device when the coverage state indicator indicates the wireless device is offline;
• and
• transmitting the data to the wireless device when the coverage state indicator indicates the wireless device is online.
