Abstract
A method for operating a cellular communications system of a type that includes a first type of terminal having real-time transmission needs and a second type of terminal having nonreal-time transmission needs. The method includes the steps of (a) determining at periodic intervals a total amount of capacity required to service the first type of terminals; (b) subtracting the determined amount from a current maximum capacity; and (c) allocating all or some of the remaining capacity, if any, to one or more of the second type of terminals.

A method for operating a cellular communications system of a type that includes a first type of terminal having real-time transmission needs and a second type of terminal having nonreal-time transmission needs, comprising the steps of:
- determining at periodic intervals a total amount of capacity required to service the first type of terminals;
- subtracting the determined amount from a current maximum capacity;
- and
- allocating all or some of the remaining capacity, if any, to one or more of the second type of terminals;
- wherein the maximum capacity is a function of a maximum reverse traffic channel capacity of a cell;
- and wherein the maximum reverse traffic channel capacity of a cell is a function of communications traffic loading in at least one adjacent cell.
A cellular communications system of a type that includes at least one base station, a first type of terminal having real-time transmission requirements, and a second type of terminal having nonreal-time transmission requirements, said first and second terminals being bidirectionally coupled to said base station through RF links, comprising:
- a load monitor module in said base station for determining, at predetermined intervals, a total reverse link load of a cell served by said base station and a total amount of capacity required to service the first type of terminals, said load monitor module subtracting the total amount of capacity to service the first type of terminals from the total reverse link load for determining a total remaining capacity;
- and
- a load control module coupled to said load monitor module and, responsive to said determined total remaining capacity, for allocating all or some of the total remaining capacity, if any, to one or more of the second type of terminals;
- wherein the total reverse link load of the cell is a function of communications traffic loading in at least one adjacent cell.
A DS-CDMA cellular communications system of a type that includes at least one base station, a first type of terminal operating with circuit switched transmissions, and a second type of terminal operating with packet switched transmissions, comprising:
- a load monitor module in said at least one base station for determining, at predetermined intervals, a total reverse link load of a cell served by said base station and a total amount of capacity required to service the first type of terminals, said load monitor module subtracting the total amount of capacity to service the first type of terminals from the total reverse link load for determining a total remaining capacity;
- and
- a load control module coupled to said load monitor module and, responsive to said determined total remaining capacity, for allocating all or some of the total remaining capacity, if any, to one or more of the second type of terminals;
- wherein the total reverse link load of the cell is a function of communications traffic loading in at least one adjacent cell.
