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.

Abstract: Drive testing for network optimization has been supplemented by the use of information measuring radio conditions collected by mobile terminals (i.e. UEs). To improve the user experience of multicast and broadcast services based on cellular telecommunications networks, such as MBMS and eMBMS, a mechanism is described that adapts UE-based reporting of measurement reports to multicast and broadcast services.
