Abstract

The invention relates to a handover management method based on mobile edge calculation, and belongs to the technical field of wireless communication. The method comprises the following steps: inventing a network architecture for deploying a mobile edge server in a dense cellular network scene, and proposing a path-free handover procedure processing method based on MEC handover decision to reduce the quality of service of users while reducing path switching request and reducing the load of a large amount of signaling of the core network. An MEC controls an X2 interface to realize the data transmission of buffer data area of a source base station through a data link formed between the base stations in a handover completion phase, an optimal length of a data link list is determined by using aMarkov decision process (MDP) model optimization method under the condition of satisfying the user service quality requirements, and by adoption of the scheme, the signaling load and delay of the core network are effectively reduced, and meanwhile higher throughput is achieved.

Description

technical field

[0001] The invention belongs to the technical field of wireless communication, and relates to a handover management method based on mobile edge computing. Background technique

[0002] In recent years, with the rapid development of mobile smart terminals, the demand for mobile communication data traffic has shown explosive growth. In order to meet the needs of users, 5G networks are developing towards densification, integration, and broadband. A dense network enhances spatial coverage through high-density deployment of small cell base stations, which can greatly increase network capacity. However, with the densification and layering of networks, mobility management is a key challenge affecting this new network architecture.

[0003] Based on the X2 handover decision process, the target base station makes an admission decision based on the cell load and measurement reports. If the target cell load exceeds the threshold, the target base station will reject th...
