Abstract

The invention discloses a service-driven local cooperative distributed spectrum access method, which includes: acquiring a target system and initializing and defining the target system; calculating the user's expected throughput; and determining the decision-making utility of the user's own channel selection according to the local cooperation mechanism The function updates its own channel selection decision according to the learning algorithm; the user selects a channel based on its own updated channel selection decision, accesses the channel and performs data transmission. The invention is oriented to the access optimization of user service data, and realizes the personalized service of 5G and future wireless network access technologies. Using the system optimization method of distributed learning based on the heterogeneous characteristics of distributed user business data, an appropriate local cooperation mechanism is introduced in the channel access method, and a business-driven local cooperative distributed learning algorithm is proposed to interact with local information. The smaller cost gradually converges to the global optimal state, which realizes the optimization of the throughput of the network system.

Description

technical field [0001] The invention relates to the field of wireless access networks in communication networks, in particular to a service-driven local cooperative distributed spectrum access method. Background technique [0002] In order to solve the serious shortage of spectrum resources faced by 5G networks, opportunistic spectrum access technology based on cognitive radio, which can effectively improve spectrum utilization, plays an important role. Cognitive radio technology is used in the research of microcellular network, which is called cognitive small cell network (Cognitive Small Cell, CSC). Cognitive microcells have the ability of cognitive radio to detect the radio environment, discover available idle spectrum channel resources, and dynamically adjust access parameters. Cognitive micro cells use opportunistic spectrum access technology to dynamically access better spectrum according to environmental conditions to provide business transmission services for their ...
