Method for reporting load and method for reducing load for cell

Abstract

The invention relates to a method for reporting load and a method for reducing load for a cell. The method for reporting load comprises the following steps: the upper threshold and the lower threshold of each IRAT (Inter-Radio Access Technology) adjacent cell are determined according to the indication (in a request of a request cell) on current available capacity of the request cell as well as the parameters configured for all the IRAT adjacent cells; the resource state of each IRAT adjacent cell per se is monitored according to the upper threshold and the lower threshold; and when the resource state of each IRAT adjacent cell meets the report conditions, the IRAT adjacent cell sends a resource state report to the request cell. By adopting the methods, the load conditions of different systems in each cell can be better adjusted, and the purpose of balancing load of each cell can be better achieved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a load reporting method and a cell load reducing method. Background technique [0002] In the prior art, the inter-system mobile load balancing (IRAT MLB) technology is generally used to deal with the problem of unbalanced traffic among multiple cells of different systems. In the above-mentioned inter-system mobile load balancing technology, the traffic status between each cell is usually discovered through the resource status reporting mechanism, so as to reasonably adjust the load status of each cell and improve the utilization rate of wireless resources. [0003] For example, if the load of a certain cell a in a radio access technology (RAT) is in a high load state, the cell a will start to transfer to its adjacent different radio access technology (IRAT) cell, that is, the different RAT ( IRAT) neighbor cell offload (offload) algorithm, the user terminal (UE) of...

Problems solved by technology

[0023] It can be seen from the above that since the upper threshold T set by OM for cells b and c u and the lower threshold T l Both are fixed values, so when the available capacity of cell b is significantly greater than that of cell c, the requesting cell a may still select cell c with a small available capacity as the target cell for load shedding instead of cell b with a large available capacity Load shedding, so that the load status of each cell cannot be well adjusted to achieve a good load balance; in addition, because cell c is already overloaded, what is reported to the requesting cell a is still the available capacity of the cell c , but the requesting cell a does not know the lower threshold of the cell c, and can only judge whether to perform load shedding based on the received available capacity, so that the requesting cell a will still perform the load shedding operation to the cell c when the target cell is overloaded , increasing the load of the target cell c, so that the load status of each cell in different systems cannot be well adjusted to achieve a good load balance
