Title:

DUAL CONNECTIVITY MODE OF OPERATION OF A USER EQUIPMENT IN A WIRELESS COMMUNICATION NETWORK

Document Type and Number:

WIPO Patent Application WO/2015/108389

Kind Code:

A1

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.
