Method for reporting load and method for reducing load for cell

A cell and report technology, applied in the direction of network traffic/resource management, digital transmission system, electrical components, etc., can solve the problems of not knowing the lower threshold, increasing the load of the target cell c, and not being able to select the load reduction of the cell b with large available capacity, etc. , to achieve the effect of load balancing

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

Embodiment Construction

[0064] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0065] The invention provides a load reporting method and a cell load reducing method. In the method of load reporting, each IRAT neighboring cell can determine the upper and lower thresholds of each IRAT neighboring cell according to the request of the requesting cell, the current available capacity of the requesting cell, and the overload threshold, and then each IRAT neighboring cell can and the upper threshold to monitor its own resource status, and when the resource status of the IRAT neighboring cell meets the reporting conditions, the IRAT neighboring cell sends a resource status report to the requesting cell, so that the load status of each cell in different systems can be better adjusted, and it is better To realize the load ...

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...
