DUAL CONNECTIVITY MODE OF OPERATION OF A USER EQUIPMENT IN A WIRELESS COMMUNICATION NETWORK
First Claim
1. A method for performing a packet data convergence protocol (PDCP) counter check in a wireless communication system supporting a dual connectivity of a user equipment (UE), the method comprising:
- receiving, by a master base station, a request message including information for checking a PDCP count from a secondary base station; and
in response to receiving the request message, performing, by the master base station, a PDCP counter check procedure to verify a value of the PDCP count, based on the information for checking the PDCP count,wherein the value of the PDCP count is associated with a secondary cell group (SCG) bearer established in the secondary base station.

Abstract
A system and method provide a security aspect for a UE in dual connectivity mode of operation in wireless communication networks. The system and method provide secure simultaneous transmission and reception in a secure manner between a User Equipment (UE) and one or more eNodeBs (eNBs) configured in an inter-eNB carrier aggregation scenario. The system establishes of a security context between the UE and the Secondary eNB (SeNB) using the RRC signaling between the UE and the Master eNB (MeNB), when a plurality of SCells within SeNB are added simultaneously. The system also detects the intruder in the user data radio bearers, while a UE is operating in dual connectivity mode of operation.

8. A master base station for performing a packet data convergence protocol (PDCP) counter check in a wireless communication system supporting a dual connectivity of a user equipment (UE), the master base station comprising:
-
a transceiver; and a processor configured to; receive, via the transceiver, a request message including information for checking a PDCP count from a secondary base station; and in response to receiving the request message, perform a PDCP counter check procedure to verify a value of the PDCP count, based on the information for checking the PDCP count, wherein the value of the PDCP count is associated with a secondary cell group (SCG) bearer established in the secondary base station. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory storage medium having stored therein instructions which cause, when executed by at least one processor of a master base station, the at least one processor to perform at least one operation which comprises:
-
receiving, by the master base station, a request message including information for checking a PDCP count from a secondary base station; and in response to receiving the request message, performing, by the master base station, a PDCP counter check procedure to verify a value of the PDCP count, based on the information for checking the PDCP count, wherein the value of the PDCP count is associated with a secondary cell group (SCG) bearer established in the secondary base station. - View Dependent Claims (16, 17, 18, 19, 20)
