Abstract

A method of registering a mobile device with an access point, is provided in which the mobile device preregisters with access points nearby in order to accelerate the registration process when roaming is initiated. Roaming may be initiated when the SNR is increasing relative to the current access point and decreasing relative to another access point.

Claims

1. A method of registering a mobile device with an access point, comprising the steps of:

(a) said mobile device sending a pre-registration request to the access point;

(b) said access point requesting authentication of said mobile device from a server;

(c) said server authorizing said mobile device to access said access point;

(d) said access point recording an address of the mobile device in an pre-register table; and

(e) said access point sending a second address, a network address and a time to live to the mobile device.

2. The method of claim 1 wherein, said mobile device stores said second address, said network address and said time-to-live within a database.

3. The method of claim 2 wherein said access point contains updateable firmware.

4. The method of claim 3 wherein a SNR is used by said mobile device to determine whether to roam to said access point.

5. A method for a mobile device to roam from a first access point to a second access point, comprising the steps of:

(a) determining when the signal to noise ratio is increasing from said first access point and decreasing from said second access point;

(b) sending a registration request to said second access point;

(c) sending said registration request to an advance server;

(d) said advance server redirecting traffic to the mobile device through a destination IP associated with the mobile device;

(e) said advance server sending confirmation to the mobile device;

(e) after the mobile device receives the confirmation from the advance server, redirecting traffic to said advance server.

6. The method of claim 5, wherein a threshold is determined for a time in which said signal to noise ratio must be increasing from said second access point.

7. The method of claim 6, wherein said mobile device registers with said second access point after said threshold has passed.

8. The method of claim 7 wherein said mobile device pre-registers with said second access point.
