Assignee: VIVO MOBILE COMMUNICATION CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A terminal, comprising: a processor; a storage; and a computer program stored in the storage and configured to be executed by the processor, wherein the processor is configured to execute the computer program, to implement the following steps:
receiving user plane data transmitted by a network-side equipment;
performing integrity check on the user plane data based on user-plane-data integrity check configuration information,
wherein, before the performing the integrity check on the user plane data based on the user-plane-data integrity check configuration information, the processor is further configured to execute the computer program to implement: receiving the user-plane-data integrity check configuration information transmitted by the network-side equipment,
wherein the terminal operates in a dual connectivity (DC) system and the network-side equipment acts as a secondary node (SN) in the DC system;
after the performing the integrity check on the user plane data based on the user-plane-data integrity check configuration information, the processor is further configured to execute the computer program to implement: transmitting integrity check failure information to a master node (MN) in the DC system in case that the user plane data fails the integrity check;
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.
