Abstract: 1. Method for Internet access with modem at user side connecting to modem at ISP/Central Computer side, via Public Switched Telephone Networks, the method comprising the steps of: disconnections of the direct physical PSTN line between user modem and ISP/Central Computer modem when not in use for data transmissions within the same user online Internet session; reconnections of the direct physical PSTN line/re-establishments of modem-to-modem data link between user modem and ISP/Central Computer modem for Internet access when user's Application Programs/Browser requires Internet access within the same user online session; the user and ISP/Central Computer modems are either: (i) kept "live" for a preset time period since last PSTN disconnection, user reconnects the direct physical PSTN line within the preset time period and be immediately Online again thus bypassing present 10-25 seconds duration modem negotiation to continue the same Session from where was left off retaining the same assigned Session IP Address, thus insulating user's Application Programs/Browsers from the PSTN disconnection/reconnection events hence preserving same user online session continuity or (ii) having a pre-arranged, and/or common, modem connection settings for user to connect to ISP thus bypassing present 10-25 seconds duration modern negotiation or (iii) having the ISP maintains a 'State Information' of all users by their Caller-ID containing permanent details of user's specific modem connection settings and details of user's current assigned IP Address for the Session, to select/initialise an appropriate ISP Modem Driver corresponding to the incoming Caller-ID before the incoming line is picked up by the modem unit, thus bypassing present 10-25 seconds duration modem negotiation. 2. Method for Internet access with modem at user side connecting to modem at ISP/Central Computer side, via Public Switched Telephone Networks, with disconnections of the direct physical PSTN line between user modem and ISP/Central Computer modem when not in use for data transmissions within the same user online Internet session; with reconnections of the direct physical PSTN line/re-establishments of modem-to-modem data link between user modem and ISP/Central Computer modem for Internet access when user's Application Programs/Browser requires Internet access within the same user online; said Method disconnects the physical PSTN when not in use for data transmissions as when webpage completed downloading for viewing. 3. Method for Internet access with modem at user side connecting to modem at ISP/Central Computer side, via Public Switched Telephone Networks, with disconnections of the direct physical PSTN line between user modem and ISP/Central Computer modem when not in use for data transmissions within the same user online Internet session; with reconnections of the direct physical PSTN line/re-establishments of modem-to-modem data link between user modem and ISP/Central Computer modem for Internet access when user's Application Programs/Browser requires Internet access within the same user online; said Method disconnects the direct physical PSTN line line between user modem and ISP modem when not in use for data transmissions as when answering incoming voice call on same line; with reconnections of the direct physical PSTN line between user modem and ISP modem/re-establishments of modem-to-modem data link between user modem and ISP modem for Internet access as when finished answering incoming voice call on same line; the user and ISP/Central Computer modems are either: (i) kept "live" for a preset time period since last PSTN disconnection, user reconnects the direct physical PSTN line within the preset time period and be immediately Online again thus bypassing present 10-25 seconds duration modem negotiation to continue the same Session from where was left off retaining the same assigned Session IP Address, thus insulating user's Application Programs/Browsers from the PSTN disconnection/reconnection events hence preserving same user online session continuity (ii) having a pre-arranged, and/or common, modem connection settings for user to connect to ISP thus bypassing present 10-25 seconds duration modem negotiation (iii) having the ISP maintains a 'State Information' of all users by their Caller-ID containing permanent details of user's specific modem connection settings and details of user's current assigned IP Address for the Session, to select/initialise an appropriate ISP Modem Driver corresponding to the incoming Caller-ID before the incoming line is picked up by the modem unit, thus bypassing present 10-25 seconds duration modem negotiation. 4. A method as claimed in Claim 1 or 2 or 3, the ISP dials to alert user when it needs to transmit data to user and the physical PSTN line is disconnected, user Software Package upon detecting the ISP's Caller-ID dials to reconnect the physical PSTN line. 5. A method as claimed in Claims 1 or 2 or 3 or 4, said method having the Internet Service Provider technically implements a PBX module to switch the reconnecting PSTN line to the same Modem Unit #(or Port#, or Datachannel) before, the ISP's Modem Unit (or Port, or Datachannel) is kept 'live' for a preset time period since last PSTN disconnection, users reconnect the PSTN line within the preset time period and be immediately Online again to continue the same Session from where was left off retaining the same assigned Session IP Address. 6. A method as claimed in Claim 5, said method having the Internet Service Provider technically implements a PBX module which monitors incoming calls extracting DTMF Caller-ID and checks against existing maintained Table of Modem Unit #(or Port #, or Datachannel) / Caller-ID to switch the reconnecting PSTN line to the same Modem Unit #(or Port#, or Datachannel) before. 7. A method as claimed in Claims 5 or 6, said method having the PBX module technically implemented by the Telecommunication Service Provider in the Exchange Switching Software, so that reconnecting calls within a preset time period, are routed to the same Port # / Datachannel before, the Port # /Datachannel being reserved for a preset time period since user last disconnects; the ISP's Modem Unit(or Port or Datachannel) is kept 'live' for a preset time period since last PSTN disconnection, users reconnect the PSTN line within the preset time period and be immediately Online again to continue the same Session from where was left off retaining the same assigned Session IP Address. 8. A method as claimed in Claim 7, said method having the PBX module technically implemented by the Telecommunication Service Provider in the Exchange Switching Software, so that reconnecting calls within a preset time period, based on their Caller-IDs are routed to the same Port # / Datachannel before, the Port#/ Datachannel being reserved for the Caller-ID for a preset time period since user last disconnect. 9. A method as claimed in Claims 1 or 2 or 3 or 4, said method having a pre-arranged, and/or common, modem connection settings for user to connect to ISP. 10. A method as claimed in Claim 9, where the ISP checks a Table of current Session IP assigned / Caller-ID to ensure the reconnecting user gets assigned the same IP Address at every subsequent reconnections if reconnecting within a preset time period since last physical PSTN line disconnection. 11. A method as claimed in Claims 1 or 2 or 3 or 4, said method having the Internet Service Provider technically implements a PBX module to switch the reconnecting PSTN line to the same Modem Unit #(or Port#, or Datachannel) before, the ISP's Modem Unit(or Port, or Datachannel) is kept 'live' for a preset time period since last PSTN disconnection, users reconnect the PSTN line within the preset time period, to re-negotiate/re-train/re-synchronise modem-to-modem data link, to continue the same Session from where was left off retaining the same assigned Session IP Address. 12.
