Title: Transient tunneling for dynamic home addressing on mobile hosts
Inventor: THUEL SANDRA R
IPC: H04L29/12
Filed: 2001-02-22
Abstract: Portable and/or mobile IP hosts desiring to connect to the Internet can dynamically acquire a home address and other configuration information through DHCP when powering up in a foreign network. A two-stage configuration procedure is used. First, the mobile host uses the M-IP protocol to establish contact with an addressing element, referred to as a bootstrapping agent, that is usually co-located with a M-IP Home Agent, and that allocates a temporary home address for the mobile host. The temporary address is used to create a temporary tunnel.  Second, this temporary tunnel is used as the communication vehicle over which standard DHCP transactions take place. The present invention is thus arranged to use a) M-IP as the signaling mechanism for reaching the home network and dynamically allocating a temporary home address for the mobile host; and b) DHCP to allocate a permanent home address and any other configuration state for the mobile host.
Patent CA-2338890-A1 (CA)
Inventor: DE BEER LEON
IPC: H04M1/27485
Filed: 1999-07-13
Abstract: A telephone is provided with dialling means (120) to output a dialled number  signal and a route determining means (121, 127) for determining an access co de to route the telephone call via a preferred route provided by a service provider. A keypad (122) of the telephone is provided with a key (128) for generating a user intervention to prevent automatic operation of the route determining means to insert an access code so that, in normal use, the user is required only to input the call destination telephone number to achieve optimum routing. The user however has the option of intervening to prevent automatic call routing by actuating a function key of the telephone keypad. Calls routed to a service provider may be authenticated using an authentication procedure in which an authentication data signal is transmitt ed to the telephone which encrypts the data using an encryption key before returning the encrypted authentication data signal. The telephone is suitabl e for domestic and business use to provide optimum routing with minimum operat or input and automatic authentication without use of PIN numbers.
