Flexible indoor network architecture design and resource allocation method

Abstract

The invention discloses a flexible indoor network architecture design and a resource allocation method. According to the method, a large number of evolved access points (E-AP) (Evoluted Access Point) with low power consumption and low cost and adopting double-rule geometric distribution are introduced, the central idea of a software defined network SDN (Software Defined Network) is used for controlling the E-APs to realize indoor software defined extended network architecture. A reasonable resource configuration and automatic mobile management scheme suitable for the communication of a large number of indoor mobile devices is provided. In the scheme, the information of mobile UE (User Equipment) is collected by the combined use of the E-APs and an environmental perception sensor, the E-APs are configured in combination with an expected speed and a transition probability matrix, a higher speed at the moment is ensured, and the allocation of the E-APs at the next moment can be predicted in advance, thereby shortening the delay and realizing seamless connection. The method is a combination of communication and computing, which can guarantee a higher communication rate, better communication quality and more flexible network architecture.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the field of resource allocation and autonomous mobile management in an ultra-dense network, a reasonable graph structure and mobile edge computing. Background technique [0002] In order to ensure a higher communication rate and better communication quality, it is an inevitable technical requirement to reduce the cell radius, improve the spatial reuse rate of spectrum resources, and improve the transmission capacity per unit area. In the existing wireless communication system, the reduction of cell radius is accomplished by cell splitting. However, due to the ever-shrinking coverage of the cell, it is difficult to obtain the optimal site location, and it is difficult to implement further splitting of the cell. Therefore, the system capacity can only be increased by increasing the number of low-power nodes, thus forming an ultra-densely deployed network architecture. In an ul...

Problems solved by technology

Therefore, each stage takes a certain amount of time, and in this process, the UE cannot send and receive data, which may cause interruption of communication or loss of data packets sent to the old AP link, affecting the quality of service (QoS) of transmission. )

Therefore, the existing indoor network architecture has problems such as large network delay, low flexibility, and the need to improve the mobile rate. A flexible network structure and resource allocation method is required.
