CROSS-REFERENCE TO RELATED APPLICATION

The present application is the U.S. national phase of PCT Application No. PCT/CN2018/090795 filed on Jun. 12, 2018, which claims a priority of the Chinese patent application No. 201710454150.3 filed on Jun. 15, 2017, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of communication technology, in particular to a data radio bearer integrity protection configuration method, a User Equipment (UE) and a network device.

BACKGROUND

Along with the development of the wireless mobile communication technology, a high data rate, a low delay and low cost are increasingly demanded. In a Long Term Evolution (LTE) system, Dual Connectivity (DC)-based network architecture has been introduced. In a DC scenario, a Data Radio Bearer (DRB) includes a Secondary Cell Group (SCG) bearer, a Master Cell Group (MCG) bearer and a split bearer.

In a 5th-Generation (5G) mobile communication system (also called as a New Radio (NR) system), a DC scenario similar to that in the LTE system has been introduced so as to transmit data at a high data rate, a low delay and high reliability. Although it is able to transmit the data at the high data rate, the low delay and the high reliability in the DC scenario, a DRB failure may probably occur during the actual wireless data transmission or a switching process between a master cell and a secondary cell. Hence, a DRB integrity protection process will be introduced into the 5G system so as to ensure consistency in data volumes received and transmitted via the DRB. However, there is currently no scheme for triggering the DRB integrity protection process in the related art.
