Abstract: The embodiments herein provide a method and system for creating a secure connection for a User Equipment (UE) in a wireless network including a UE, carrier aggregated with at least one first serving frequency served by a first eNB and at least one second serving frequency served by a second eNB. A unique non-repetitive security base key associated with the second eNB is generated using a freshness parameter and security key associated with the first eNB. The use of a different freshness parameter for each security base key derivation avoids key stream repetition. Further, a user plane encryption key is derived based on the generated unique non-repetitive security base key associated with the second eNB for encrypting data transfer over at least one data radio bearer.

Abstract: Embodiments herein provide a method for identity management across multiple planes. The method includes receiving, by a MCPTT server, a first request message to establish a call between a first MCPTT client and the one or more second MCPTT client from a signaling plane entity. The first request message includes an application plane identity of the one or more second MCPTT client. Further, the method includes translating, at the MCPTT server, the application plane identity of the one or more second MCPTT client to a signaling plane identity of the one or more second MCPTT client. Furthermore, the method includes sending, by the MCPTT server, the one or more second request message including the signaling plane identity of the one or more second MCPTT client to the second MCPTT client for establishing the call via the signaling plane entity.
