Resource allocation method and multi-mode controller

Abstract

The invention discloses a resource allocation method and a multi-mode controller. By the method, when a plurality of wireless access systems are subjected to co-transmission, the reasonableness of allocating resources to data streams in the wireless access systems is improved, and the resource utilization rate and system throughput are improved. The method comprises the following steps of: determining the data sending amount and data request amount of each data stream in a transmission path in the current period; determining the total data sending amount and total data request amount of the transmission path in the current period according to the data sending amount and data request amount of each data stream; and determining the data request amount of each data stream in the transmission path in the next period according to the data sending amount and data request amount of each data stream in the current period, the total data sending amount and total data request amount of the transmission path in the current period, and the allocation bandwidth of the transmission path. Through the technical scheme, the reasonableness of allocating the resources to the data streams in the wireless access systems is improved, and the resource utilization rate and system throughput are improved.

Problems solved by technology

[0004] At present, the multi-mode controller allocates bandwidth resources separately for the data streams of each wireless access standard. Although it is simple to allocate bandwidth resources individually, because the data streams of each wireless access standard have different bandwidth requirements and transmission rates, if the The way of allocating bandwidth resources separately will make the bandwidth resource allocated to the data flow of the wireless access standard with a higher transmission rate larger, and the bandwidth resource allocated to the data flow of the wireless access standard with a lower transmission rate is smaller; when in In a certain period of time, when the traffic volume of the data flow of the wireless access standard with a low transmission rate is large, there will be insufficient bandwidth resources, while the traffic volume of the data flow of the wireless access standard with a high transmission rate is small. At this time, there are many idle broadband resources; therefore, using this method of individually allocating bandwidth resources leads to unreasonable allocation of resources to data streams of each wireless access system, and unbalanced resources allocated to data streams of each wireless access system. As a result, resources cannot be fully utilized, which in turn leads to the problem of low system throughput of the entire network system
