Abstract
System and apparatus for actively managing calls in a wireless cellular network. A host receives input data from a plurality of cells regarding the status of calls in that cell. Input data may include call variables such as carrier signal strength over interference (C/I), forward and reverse link power, beam and channel assignments, handoff status, and triangulation data regarding location/movement of active calls. The host processes the input data with reference to known cell neighborhoods, and creates output data for each cell that includes information on other active calls in the neighborhood. The output data then updates the cell with information regarding active calls in the cell's vicinity. The cell may then make adjustments to call variables taking into account local interference conditions. Further, through reference to (1) fixed data regarding the network such as topography or statistics, and/or (2) immediate past historical data regarding active calls, the host may also create output data taking into account predicted impending interference conditions.

STATEMENT UNDER ARTICLE 19(1)
Applicant has amended claims 1 and 14. Claim 1 has been amended to include the limitations of dependent claim 6 and claim 14 has been amended to include the limitations of dependent claim 19. Claims 6 and 19 have been canceled. Claims 1 and 14 also include additional amendments directed to "temporarily blocking ones of the wireless communications." These amendments are clearly supported by the original disclosure at page 21, in lines 25-35. The amendments to claims 1 and 14 have no impact on the disclosure and drawings as filed.
Claims 1 and 14, as amended, require "modifying ones of the transmission characteristics so as to allow ones of the wireless communications to continue at artificially sub-optimum transmission conditions for the sake of improving transmission conditions for other wireless communications" and "temporarily blocking ones of the wireless communications if the artificially sub-optimum transmission conditions are not feasible for wireless communications."
European Patent Application number 90313301.5, entitled CELLULAR RADIOTELEPHONE DIAGNOSTIC SYSTEM, fails to teach either of these elements. The disclosed Diagnostic System monitors and optimizes the transmission characteristics of wireless communications. However, the disclosure does not provide for operation at "artificially sub-optimum transmission conditions" or for "temporarily blocking ones of the wireless communications" as required by the present amendments to claims 1 and 14.
European Patent Application number 93202280.9 (corresponding to United States Patent No. 5,475,868, entitled CELLULAR RADIO SYSTEM HAVING CHANNEL EVALUATION AND OPTIMAL CHANNEL SELECTION VIA TRIAL USE OF NON-ASSIGNED CHANNELS) teaches a system for selecting cellular radio channels. However, the system does not disclose operation at "artificially sub- optimum transmission conditions" or "temporarily blocking ones of the wireless communications" as required by the present amendments to claims 1 and 14.
The article entitled "Adaptive Channel Allocation in TACS" by M. Almgren, et al. discloses a method of assigning channels to a base station based upon channel transmission characteristics. However, the article does not teach a system that operates at "artificially sub-optimum transmission conditions" or that is capable of "temporarily blocking ones of the wireless communications" as required by claims 1 and 14, as amended.
