Technique for achieving connectivity between telecommunication stations
View Patent ↗A technique for enabling a secure, point-to-point wireless connection between a secondary computer (e.g., a personal digital assistant, etc.) and a primary computer (e.g., a notebook, a desktop, etc.) is disclosed. The primary computer is associated with an extended infrastructure through an access point. The present invention enables the secondary computer to communicate either with the associated primary computer or with an extended network indirectly through the access point.
1. A method comprising:
receiving a first frame from a shared-communications channel wherein said first frame comprises:
(i) a first basic service set identifier;
(ii) a first internet protocol address;
(iii) a second internet protocol address; and
(iv) a first frame body;
passing said first frame based on said first basic service set identifier;
tagging said first frame body with a tag that represents said first basic service set identifier; and
transmitting a second frame into said shared-communications channel wherein said second frame comprises:
(i) a second basic service set identifier that is different from said first basic service set identifier;
(ii) a third internet protocol address that is different from said first internet protocol address;
(iii) said second internet protocol address; and
(iv) a second frame body wherein said second frame body comprises said first frame body and said tag.
2. The method of claim 1 wherein said first basic service set identifier is a medium access control address of a wireless interface in an access point.
3. The method of claim 1 wherein said passing admits frames comprising an infrastructure basic service set identifier and frames comprising an independent basic service set identifier.
4. The method of claim 1 wherein said first frame comprises a user data block and said second frame comprises said user data block.
5. An apparatus comprising:
a receiver for receiving a first frame from a shared-communications channel wherein said first frame comprises:
(i) a first basic service set identifier;
(ii) a first internet protocol address;
(iii) a second internet protocol address; and
(iv) a first frame body;
a processor for:
(i) passing said first frame based on said first basic service set identifier; and
(ii) tagging said first frame body with a tag that is representative of said first basic service set identifier;
a transmitter for transmitting a second frame into said shared-communications channel wherein said second frame comprises:
(i) a second basic service set identifier that is different from said first basic service set identifier;
(ii) a third internet protocol address that is different from said first internet protocol address;
(iii) said second internet protocol address; and
(iv) a second frame body wherein said second frame body comprises said first frame body and said tag.
6. The apparatus of claim 5 wherein said first basic service set identifier is a medium access control address of a wireless interface in an access point.
7. The apparatus of claim 5 wherein said passing admits frames comprising an infrastructure basic service set identifier and frames comprising an independent basic service set identifier.
8. The apparatus of claim 5 wherein said first frame comprises a user data block and said second frame comprises said user data block.
9. A method comprising:
receiving a first frame from a shared-communications channel wherein said first frame comprises:
(i) a first basic service set identifier;
(ii) a first internet protocol address; and
(iii) a first frame body;
passing said first frame based on said first basic service set identifier;
tagging said first frame body with a tag that is representative of said first basic service set identifier;
translating said first internet protocol address to a second internet protocol address; and
transmitting a second frame into said shared-communications channel wherein said second frame comprises:
(i) a second basic service set identifier;
(ii) said second internet protocol address; and
(iii) a second frame body wherein said second frame body comprises said first frame body and said tag.
10. The method of claim 9 wherein: said first frame comprises a third internet protocol address and a user data block; and said second frame comprises said third internet protocol address and said user data block.
11. The method of claim 10 wherein said user data block is encrypted.
12. The method of claim 9 wherein said first basic service set identifier is a medium access control address of a wireless interface in an access point.
13. The method of claim 9 wherein said passing admits frames comprising an infrastructure basic service set identifier and frames comprising an independent basic service set identifier.
14. An apparatus comprising:
a receiver for receiving a first frame from a shared-communications channel wherein said first frame comprises:
(i) a first basic service set identifier;
(ii) a first internet protocol address; and
(iii) a first frame body;
a first processor for passing said first frame through a basic service set identifier filter and tagging said first frame body with a tag that is representative of said first basic service set identifier;
a second processor for translating said first internet protocol address to a second internet protocol address; and
a transmitter for transmitting a second frame into said shared-communications channel wherein said second frame comprises:
(i) a second basic service set identifier;
(ii) said second internet protocol address; and
(iii) a second frame body wherein said second frame body comprises said first frame body and said tag.
15. The apparatus of claim 14 wherein:
said first frame body comprises a third internet protocol address and a user data block; and
said second frame body comprises said third internet protocol address and said user data block.
16. The apparatus of claim 15 wherein said user data block is encrypted.
17. The apparatus of claim 14 wherein said first basic service set identifier is a medium access control address of a wireless interface in an access point.
18. The apparatus of claim 14 wherein said passing admits frames comprising an infrastructure basic service set identifier and frames comprising an independent basic service set identifier.
