SOCKET MANAGEMENT FOR ALWAYS-ON DATA CONNECTIONS

摘要

A method of automatically keeping sockets open for always-on applications in a GPRS context is provided. Information is maintained by each wireless device identifying each APN (access point name)-port pair associated with a PDP (packet data protocol) context used by an always-on application. Upon the PDP context becoming available after having become unavailable, a socket is registered for each port-APN pair associated with the PDP context.
