Abstract
The continuous development of wireless communication theory and engineering practice technology has led to the heterogeneous wireless network situation represented by 4G and wireless technology. At the same time, with the rapid development of wireless services based on mobile internet, its complex business types and high traffic demand pose a huge challenge to the resource scheduling of operators. In this paper, the current status of research and application of heterogeneous wireless networks in China is reviewed, the key technologies and promotion schemes are analyzed, the impact of existing network planning concepts is discussed, and the relevant issues are given strategic suggestions. In order to better study the resource consumption of user service models in different access networks under heterogeneous networks, a multi-QoS traffic algorithm for mixed services under heterogeneous networks is proposed. This algorithm is based on the mixed services in various access networks, and takes the guarantee of the mixed services in different access networks of heterogeneous networks as the premise to accurately evaluate the traffic from the perspective of business identification. According to the number of active users, the bandwidth requirements of different user sizes are assessed, and the network planning is guided to expand reasonably.
