Abstract: Embodiments herein disclose a method for executing conditional handover by a UE in a wireless communication network. The method may include receiving an RRC reconfiguration message from a source cell of the wireless communication network. The RRC reconfiguration message may include a handover configuration and determining whether a CHO configuration may be provided in the handover configuration. Further, the method may include performing one of: continuing an RLM timer and an RLM procedure on the source cell, in response to determining that the CHO configuration is provided in the handover configuration; and stopping the RLM timer and suspending the radio link monitoring procedure on the source cell, in response to determining that the CHO configuration is not provided in the handover configuration. The method may then include executing the CHO from the source cell to a candidate target cell in the wireless communication network based on the CHO configuration.

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.
