Data distribution method and device

Abstract

The invention proposes a data distribution method and device, and relates to the field of mobile communication. The method comprises the steps: determining an initial data amounts distributed to a main base station and an auxiliary base station according to the throughput capacity historical information of a wireless bearer; adjusting the initial data amounts according to an expected caching value of the auxiliary base station for the wireless bearer, and determining the initial adjustment data amounts distributed to the main base station and the auxiliary base station; adjusting the initial adjustment data amounts of all wireless bearers of a user according to the minimum expected caching value of the auxiliary base station for the user, and determining the distributed data amounts distributed by each wireless bearer to the main base station and the auxiliary base station. The method distributes the data amounts of the wireless bearers for the main base station and the auxiliary base station based on the throughput capacity historical information of the main base station and the auxiliary base station, adjusts the caching requirements of the bearers and the user according to the auxiliary base station, thereby guaranteeing that the data amount distributed to the auxiliary base station cannot exceed the caching capability of the auxiliary base station while making the most of the resources of the main base station and the auxiliary base station.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a data distribution method and device. Background technique [0002] In the research phase of 3GPP Rel-10 / 11, 3GPP proposed a carrier aggregation technology that achieves a larger bandwidth by aggregating multiple carriers, thereby providing a faster data transmission rate. In the application scenario of carrier aggregation technology, RRH (Radio Remote Head, radio remote unit) is directly connected to the macro base station through high-quality optical fiber, and the signaling transmission delay between each other is small, which is suitable for centralized scheduling in the macro base station. Entering the research stage of 3GPP Rel-12, NTT DoCoMo Company proposed the small cell enhancement research project and proposed the non-ideal backhaul scenario. In this scenario, the centralized scheduling mechanism is difficult to apply, and distributed MAC (Media Access Control, Me...
