Abstract

A wireless telecommunications network that uses a first frequency spectrum for wireless communications in a plurality of generally contiguous wireless coverage areas also has available a second frequency spectrum for wireless communications in a high-traffic wireless coverage area. Mobile stations in the high-traffic wireless coverage area are classified as either static or dynamic based on determinations of their speeds. The wireless telecommunications network uses the first frequency spectrum for wireless communications with dynamic mobile stations in the high-traffic wireless coverage area and uses the second frequency spectrum for wireless communications with static mobile station in the high-traffic wireless coverage area. The wireless telecommunications network may instruct the mobile stations in the high-traffic coverage area to use the appropriate frequency spectrum.

Claims

1. In a wireless telecommunications network having a plurality of generally contiguous wireless coverage areas, in each of said wireless coverage areas said wireless telecommunications network using at least a first downlink frequency band for communicating with mobile stations located therein, a method of increasing the wireless capacity of at least one of said wireless coverage areas, said method comprising:

said wireless telecommunications network maintaining tracking records for mobile stations located in said at least one of said wireless coverage areas;

said wireless telecommunications network classifying said mobile stations located in said at least one of said wireless coverage areas as either static or dynamic based on information contained in said tracking records;

said wireless telecommunications network using said first downlink frequency band for communicating with dynamic mobile stations located in said at least one of said wireless coverage areas; and

said wireless telecommunications network using a second downlink frequency band for communicating with static mobile stations located in said at least one of said wireless coverage areas, said second downlink frequency band being different than said first downlink frequency band.

2. The method of claim 1, wherein said second downlink frequency band does not overlap said first downlink frequency band.

3. The method of claim 1, further comprising:

determining a speed of a mobile station located in said at least one of said wireless coverage areas;

if said speed is below a threshold value, said wireless telecommunications network classifying said mobile station as a static mobile station; and

if said speed is above a threshold value, said wireless telecommunications network classifying said mobile station as a dynamic mobile station.

4. The method of claim 3, wherein determining a speed of a mobile station comprises:

determining a first position of said mobile station at a first time; and

determining a second position of said mobile station at a second time.

5. The method of claim 3, further comprising:

in response to classifying said mobile station as a static mobile station, said wireless telecommunications network instructing said mobile station to monitor said second downlink frequency band.

6. The method of claim 3, further comprising:

in response to classifying said mobile station as a dynamic mobile station, said wireless telecommunications network instructing said mobile station to monitor said first downlink frequency band.
