Method and apparatus in a portable subscriber unit for minimizing a connection setup time through a communication network
First Claim
1. A method in a portable subscriber unit for minimizing a connection setup time in a communication network comprising a wide area network, the method comprising the steps of:
- maintaining in a memory of the portable subscriber unit a list identifying a plurality of devices which are to be connected quickly through the communication network;
establishing a new connection with the communication network; and
performing, in response to establishing said new connection, when necessary for pre-programming the communication network to minimize the connection setup time for subsequent connections with said plurality of devices, at least one of the steps of;
sending names of the plurality of devices to a domain name server (DNS) of the communication network to obtain IP addresses corresponding to the names, thereby causing the DNS to cache the IP addresses of the plurality of devices for faster servicing of subsequent connections; and
transmitting a dummy Internet Protocol (IP) packet to said plurality of devices.

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

9. A portable subscriber unit for minimizing a connection setup time in a communication network comprising a wide area network, the portable subscriber unit comprising:
-
a processor for controlling the portable subscriber unit, the processor including a memory; and
a communication interface coupled to the processor for communicating with the communication network, wherein the processor is arranged and programmed to;
maintain in the memory a list identifying a plurality of devices which are to be connected quickly through the communication network;
establish a new connection with the communication network; and
perform, in response to establishing said new connection, when necessary for pre-programming the communication network to minimize the connection setup time for subsequent connections with said plurality of devices, at least one of the steps of;
sending names of the plurality of devices to a domain name server (DNS) of the communication network to obtain IP addresses corresponding to the name, thereby causing the DNS to cache the IP addresses of the devices for faster servicing of subsequent connections; and
