Abstract: Method and system for handling of special SCell selection in dual connectivity. The present invention relates to the field of wireless communication networks and more particularly to a User Equipment (UE) operating in dual connectivity mode in wireless communication networks. The principal object of the embodiments herein is to provide a method and system for handling of special SCell (PSCell) change by extending Event A3 or Event A5 to PSCell for relative comparison. Another object of the invention is to provide a method and system for handling of special SCell (PSCell) change with a new Event Ax.

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: The present disclosure relates to a method and apparatus for performing random access in a user equipment for a small cell e-NB with a small cell service area in heterogeneous e-NB cell carrier integration (dual connectivity or inter-eNB carrier aggregation) in mobile communication systems. In accordance with an aspect of the present disclosure, a method for performing random access in a mobile communication system is provided. The method includes receiving a configuration request message for configuring a Serving Cell Group (SCG) from a second eNB located in a service area of a first eNB through the first eNB; configuring an SCG cell based on the configuration request message, and sending a configuration response message in response to the configuration request message to the second eNB through the first eNB; and performing random access if there is uplink data present on a logic channel (LCH) relocated into the SCG cell.

Abstract: Provided is a method for reporting a buffer state by a user equipment accessing a first eNB and a second eNB in a communication system, the method comprising the steps of: triggering a buffer state report for new data when the new data is generated; selecting at least one eNB to which the buffer state report is to be transmitted, on the basis of the amount of uplink data to be transmitted; transmitting the buffer state report for the new data to the selected at least one eNB; receiving, from at least one eNB among the first eNB and the second eNB, a resource allocated by the at least one eNB as a response to the buffer state report; and transmitting the new data using the allocated resource.
