Method and system for multiple carrier resource allocation in LTE-advanced networks

A method for scheduling user rate allocation of a network where a network bandwidth of at least two cellular carriers is available for scheduling the user rate allocation comprising:

• aggregating, by a server, a first network bandwidth of a first cellular carrier and a second network bandwidth of a second cellular carrier into a single network for purposes of scheduling user rate allocation of the single network, wherein “rate” means “data rate”, and wherein “carrier” means “bearer”;
• ordering, by the server, the first and second cellular carriers within the single network such that there is a primary cellular carrier and a secondary cellular carrier;
• receiving, by the server, an initial primary cellular carrier user bid for resource allocation from a user for the network bandwidth of the primary cellular carrier and an initial primary cellular carrier network rate allocation for the user;
• applying, by the server, a first iterative process to determine multiple possible primary cellular carrier user solutions, each possible primary cellular carrier user solution including a proposed primary cellular carrier user rate allocation and associated price, wherein the initial inputs to the first iterative process include the initial primary cellular carrier user bid, the initial primary cellular carrier network rate allocation, a user utility function which represents a sum of multiple application utility functions, and primary cellular carrier network cost data;
• generating, by the server, based on the first iterative process, and based on the initial primary cellular carrier inputs, a primary cellular carrier shadow price for the network bandwidth of the primary cellular carrier and multiple proposed primary cellular carrier user rate allocations with associated prices based on the generated primary cellular carrier shadow price;
• selecting, by the server, an optimal primary cellular carrier user rate allocation by comparing each of the multiple proposed user rate allocations with the initial primary cellular carrier network rate allocation for the user and selecting the closest proposed primary cellular carrier user rate allocation, from among the multiple proposed secondary cellular carrier user rate allocations, to the initial primary cellular carrier network rate allocation;
• adjusting, by the server, the user utility function to account for the optimal primary cellular carrier user rate allocation;
• receiving, by the server, an initial secondary cellular carrier user bid from a user for the network bandwidth of the secondary cellular carrier and an initial secondary cellular carrier network rate allocation for the user;
• applying, by the server, a second iterative process to determine multiple possible secondary cellular carrier user solutions, each possible secondary cellular carrier user solution including a proposed secondary cellular carrier user rate allocation and associated price, wherein the initial secondary cellular carrier inputs to the second iterative process include the initial secondary cellular carrier user bid, the initial secondary cellular carrier network rate allocation, an adjusted user utility function and secondary cellular carrier network cost data;
• generating, by the server, based on the second iterative process, and based on at least the initial secondary cellular carrier inputs, a secondary cellular carrier shadow price for the network bandwidth of the secondary cellular carrier and multiple proposed secondary cellular carrier user rate allocations with associated prices based on the generated secondary cellular carrier shadow price;
• and
• selecting, by the server, an optimal secondary cellular carrier user rate allocation by comparing each of the multiple proposed secondary cellular carrier user rate allocations with the initial secondary cellular carrier network rate allocation for the user and selecting the closest proposed secondary cellular carrier user rate allocation, from among the multiple proposed secondary cellular carrier user rate allocations, to the initial secondary cellular carrier network rate allocation.
