Abstract: A method and system for minimizing the battery power consumption of user equipment (UE) during inter-frequency cell detection in a heterogeneous network is disclosed. A serving cell in the heterogeneous network provides a relaxed cell detection indication to the UE on a specified frequency for cell detection. The UE applies the relaxed cell detection for detecting the cells on the specified frequency. During inter-frequency cell detection on specified frequency, the UE discards some normal measurement gaps. The inter-frequency cell detection is delayed as compared to normal cell detection time requirement using the normal measurement gaps. The UE deactivates the relaxed detection indication, upon detecting the inter-frequency cell and performs the continuous RSRP and RSRQ measurements for detected inter-frequency cell using all the normal measurement gaps to meet normal measurement accuracy and measurement reporting requirement.

Abstract: A method and system for uplink-downlink transmission of message in a network. The method includes establishing, by a user equipment (UE), a security context for data transmission between the UE and a serving gateway in the network; generating, by the UE, in an idle mode, a data message including an encrypted data packet, the encrypted data packet being generated by encrypting a data packet to transmit to the serving gateway based on the security context; transmitting, by the UE, in the idle mode, to a base station (BS), a random access channel (RACH) message including a UE identifier (ID); receiving, by the UE, in the idle mode, from the BS, a contention resolution message including grant information for an uplink (UL) transmission; and transmitting, by the UE, in the idle mode, to the BS, the data message including the encrypted data packet.

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: 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.
