Abstract

Apparatus and method for securing a wireless communication medium are disclosed. The apparatus uses a Subscriber Identity Module (SIM) card. The method includes determining a SIM card insertion and if so, accessing SIM data and transmitting the SIM data to a base station for comparison with a local copy of authorized user data file; granting mobile unit access to base station if the information matches and otherwise indicating an access failure.

Claims

1. A method for securing a wireless communication medium using a Subscriber Identity Module (SIM) card, comprising:

determining a SIM card insertion and if so accessing SIM data and transmitting the SIM data to a base station for comparison with a local copy of an authorized user data file;

granting mobile unit access to the base station if the comparison is indicative of a match and otherwise indicating an access failure; and

if the mobile unit access is grant, determining a desired level of service; and

dynamically adjusting a number of time slots assigned to the wireless communication medium during data transmission to remain within limits of said desired level of service via the dynamically adjust number of time slots and at least one short-range wireless medium;

wherein the dynamic adjusting comprises;

determining available time-slot resources;

detecting the wireless communication medium that fails to meet said desired level of service;

allocating the wireless communication medium to a configuration having additional time slots; and

transmitting a channel assignment message including information on the allocated configuration with the additional time slots.

2. The method of claim 1, wherein the at least one short-range wireless medium conforms to an 802.11 specification.

3. The method of claim 1, wherein the at least one short-range wireless medium conforms to a Bluetooth specification.

4. The method of claim 1, wherein the at least one short-range wireless medium operates at 2.4 gigahertz.

5. A system for securing a wireless communication medium using a Subscriber Identity Module (SIM) card, comprising:

means for determining a SIM card insertion and if so accessing SIM data and transmitting the SIM data to a base station for comparison with a local copy of an authorized user data file;

means for granting mobile unit access to the base station if the comparison is indicative of a match and otherwise indicating an access failure; and

means for determining a desired level of service and dynamically adjusting a number of time slots assigned to the wireless communication medium during data transmission to remain within limits of said desired level of service via the dynamically adjust number of time slots and at least one short-range wireless medium if the mobile unit access is grant;

wherein the means for determining a desired level of service and dynamically adjusting comprises;

means for determining available time-slot resources;

means for detecting the wireless communication medium that fails to meet said desired level of service;

means for allocating the wireless communication medium to a configuration having additional time slots; and

means for transmitting a channel assignment message including information on the allocated configuration with the additional time slots.

6. The system of claim 5, wherein at least one short-range wireless medium to an 802.11 specification.

7. The system of claim 5, wherein at least one short-range wireless medium to an bluetoooth specification.

8. The system of claim 5, wherein at least one short-range wireless medium operates 2.4 gigahertz.
