THE MTSO ALLOWS FOR VIRTUALLY UNINTERRUPTED SERVICE AS A CELL'S CAPACITY REACHES THE MAXIMUM NUMBER OF CHANNELS. IN THE EVENT OF EXTREMELY HIGH USAGE WITHIN ONE CELL, THE CENTRAL COMPUTER ( "MTSO ") CAN HANDLE THE SITUATION AUTOMATICALLY BY EITHER OF THE FOLLOWING METHODS: (1) THE MTSO WILL SEARCH THE ADJACENT CELLS FOR THE CHANNEL CAPACITY TO HANDLE MORE CALLS AND AUTOMATICALLY PASS THE CALL THROUGH TO THAT CELL; AND (2) THE MTSO CAN DETERMINE IF A CALL IN PROGRESS IS ABOUT READY TO BE TRANSFERRED TO AN ADJACENT CELL AND IT WILL THEN AUTOMATICALLY TRANSFER OR "HAND -OFF" THE CALL TO THE NEXT CELL. BOTH OF THESE TRANSACTIONS ARE ACCOMPLISHED ALMOST INSTANTANEOUSLY, AND THE CELLULAR USER DOES NOT EXPERIENCE ANY INTERRUPTION IN SERVICE. WHEN THE CHANNELS IN ONE INDIVIDUAL CELL BECOME CONTINUOUSLY CONGESTED, THE PROBLEM IS ALLEVIATED BY DIVIDING THE CELL INTO MANY SEPARATE SMALLER CELLS. AS LONG AS SUFFICIENT EQUIPMENT IS AVAILABLE AND INSTALLED, THE CELLS CAN CONTINUE TO BE SPLIT INDEFINITELY. Fig. 2.5 The concept of cull splitting. TO PLACE A CELLULAR TELEPHONE CALL THE USER MUST TURN THE POWER SWITCH TO THE "ON" POSITION ON HIS CELLULAR PHONE CONTROL UNIT AND MUST BE CERTAIN THE "NO SERVICE" INDICATOR IS NOT LIT. THE USER DIALS THE DESIRED TELEPHONE NUMBER ON THE TOUCH TONE DIAL PAD AND CHECKS THE DISPLAY PANEL FOR ACCURACY, AND THEN PRESSES THE "SEND" BUTTON TO TRANSMIT -3-- 47
