Problems solved by technology

However, the migration interruption time of this carrier migration solution is mostly between tens to hundreds of milliseconds, and the memory change speed of the virtual machine is faster than the memory copy speed of the migration process, resulting in the failure of the memory copy process of the virtual machine migration operation to converge.

Abstract

The invention discloses a virtualized carrier migration method based on L3 and L2 layer protocols, which mainly solves the problem of low scheduling efficiency of C-RAN baseband pool resources in the prior art. The scheme is: the source end sends a migration request to the carrier migration control module; the carrier migration module sends a migration environment preparation message to the destination; the carrier migration control module sends a migration command to the source after receiving the destination migration environment preparation message; When the terminal performs the last round of data migration and copying for the L3 and L2 layer protocol carrier virtual machines, the L1 layer protocol virtual machine caches the processed data; after the carrier migration control module receives the data copy migration completion message, it sends the data migration copy to the destination end Completed message; the L3 and L2 layer protocol carrier virtual machines generated by the migration of the destination end are started, and the cached data is cleared, and the source end service data is sent to the destination end through the switching network. The invention realizes efficient utilization of resources, and can be applied to C-RAN baseband pool resource scheduling.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a virtualized carrier migration method, which can be used for protocols based on L3 and L2 layers. Background technique [0002] The distributed base station structure separates the baseband processing unit BBU and the radio frequency processing unit RRU in the traditional macro base station, and connects the two through optical fibers. During network deployment, the baseband processing unit, core network, and wireless network control equipment are concentrated in the computer room, and connected to the remote radio unit deployed on the planned site through optical fiber to complete network coverage, thereby reducing construction and maintenance costs and improving efficiency. The characteristic of the current RRH+BBU distributed base station is that the RRH is fixedly connected to the processing board of a certain BBU. The RRH can only transmit the baseband signal data a...
