Classification: CPC H | IPC H

Claim 0:
1. A method of integrity check, comprising:
receiving, by a terminal, user plane data transmitted by a network-side equipment;
performing, by the terminal, the integrity check on the user plane data based on user-plane-data integrity check configuration information,
wherein the terminal operates in a dual connectivity (DC) system;
wherein the user-plane-data integrity check configuration information further comprises third indication information;
the third indication information is configured to instruct the terminal to perform the integrity check on the received user plane data transmitted by another network-side equipment;
wherein before the performing, by the terminal, the integrity check on the user plane data based on the user-plane-data integrity check configuration information, the method further comprises:
receiving, by the terminal, the user-plane-data integrity check configuration information transmitted by the network-side equipment,
wherein the network-side equipment acts as a secondary node (SN) in the DC system;
after the performing, by the terminal, the integrity check on the user plane data based on the user-plane-data integrity check configuration information, the method further comprises:
in case that the user plane data fails the integrity check, transmitting, by the terminal, integrity check failure information to a master node (MN) in the DC system.
