Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to the technical field of heterogeneous network resource allocation, and relates to a heterogeneous fusion network joint user association and power allocation method supporting information security transmission. Background technique [0002] In recent years, all kinds of wireless access technologies have developed rapidly. However, the heterogeneity of wireless access technologies and the diversity of user needs make any single wireless access technology unable to meet all the business needs of users, prompting Various wireless network technologies gradually achieve efficient collaboration and converged coexistence, forming a heterogeneous converged network. [0003] Network security is one of the core issues of wireless networks, and it is also the basic condition for the successful promotion and application of wireless networks. In recent years, with the rapid incre...

Problems solved by technology

[0005] Existing research on resource allocation schemes based on eavesdropping user network scenarios rarely consider heterogeneous network scenarios. However, the heterogeneous nature of access networks may pose difficulties and challenges to resource allocation methods

In addition, the existing research on resource allocation pays more attention to the improvement of throughput, coverage and spectrum utilization, and less research on network energy efficiency performance optimization, which may lead to low network energy efficiency. For energy-efficient user equipment, transmission performance and user experience Difficult to guarantee
