Method and apparatus in a portable subscriber unit for minimizing a connection setup time through a communication network

摘要: In a portable subscriber unit ( 200 ) processor 204 is arranged and programmed to maintain 302 in memory 208 list identifying plurality of devices which are be connected quickly through communication network, establish 304 new connection with the network. The further perform, response establishing connection, when necessary for pre-programming network minimize setup time subsequent connections devices, at least one steps (a) sending names domain name server (DNS) obtain IP addresses corresponding names, thereby causing DNS cache faster servicing connections, (b) transmitting dummy Internet Protocol (IP) packet said devices.
