Abstract

The invention relates to a migration method for online VMEC service network selection, which belongs to the field of mobile communication. The method includes: S1: establishing a VMEC mathematical model; S2: scanning adjacent and accessible networks at time slot t, and performing network screening; S3: repeating S2 at time slot t+1 to obtain the initial time slot t+1 Network selection and migration placement as the initial strategy; S4: Network selection and service placement optimization: calculate and compare the three delays of the initial strategy for the t+1 time slot; update the time delay of the t+1 time slot based on the comparison results of the three delays The initial strategy obtains the optimized service migration strategy Φ(t+1) for time slot t+1; finally, the access network selection and service placement are performed according to the strategy Φ(t+1); S5: In the next time slot, repeat steps S3 and S4 , get access network selection and service migration strategy for each time slot in time T. The invention can minimize the time delay for the vehicle to select the network and formulate the service migration strategy during the moving process, and improve the service quality of the user.

Description

technical field [0001] The invention belongs to the field of mobile communication, and relates to an online VMEC service network selection migration method. Background technique [0002] As a supplement to the C-Ran architecture, Mobile Edge Computing (MEC) provides communication and powerful computing capabilities for mobile users within the range of the wireless access network. Therefore, MEC not only supports multiple applications such as driverless driving, virtual reality, augmented reality, robotics, and immersive media. There is also the advantage of heterogeneous access technologies such as 4G, 5G, WiFi and fixed connections. ETSI officially announced in 2017 that mobile edge computing entered the second phase and changed its name to Multi-access Edge Computing (MEC). After the range is extended, the MEC server can be deployed by operators in different locations (such as eNB in ​​4G and gNB in ​​5G), or co-deployed with optical fiber network and WiFi access point. ...
