Wireless network buffered message system
A network server system maintains secure Internet data message links with respective device link agents on each of many wireless end-user devices. Through a network interface, the server system receives messages from network elements, for which delivery is requested to specific software components on specific ones of the devices. A message buffer system buffers such messages for delivery, and logic determines whether one of several potential triggers has happened to cause the system to deliver buffered messages to a particular one of the devices. For at least some messages, receiving the message at the buffer will not trigger delivery. At least one trigger identifies a time-critical message, however, which can cause all buffered messages for a particular device to be delivered. Such a system balances wireless network efficiency and opportunistic delivery with a potential for fast message delivery, when needed.
