Title:
SWITCHING METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/169732
Kind Code:
A1
Abstract:
A switching method and a communication apparatus. The method comprises: a source network device sends a switching command to a terminal device and then sends at least one data packet not successfully received by the terminal device to a target network device, so that after the terminal device accesses the target network device, the target network device sends the at least one data packet received from the source network device to the terminal device. Because data packets forwarded by the source network device to the target network device comprise a data packet of the source network device that has been subjected to PDCP processing but has not received a acknowledge response from the terminal device, the data loss of the terminal device during a cross-system switching process can be effectively avoided.
