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:
A method for moving between cells by a wireless device includes receiving instructions for the wireless device to measure and report a gradient change value to apply offsets based on a plurality of speed states; identifying a speed state in which a moving speed of the wireless device is included among the plurality of speed states; obtaining an offset mapped to the speed state; first filtering a received wireless signal at a physical layer and second filtering the received wireless signal at a radio resource control layer; calculating the gradient change value corresponding to the obtained offset. The gradient change value indicates a rate of change of received signal strength with a serving cell or a rate of received signal strength difference between a neighbor cell and the serving cell. A portion of the second filtering of the received wireless signal is determined based on the calculated gradient change value.
Abstract:
A method and an apparatus are provided for determining a configuration for a radio frame. A transition from a period of inactivity to a period of activity is detected in a configured discontinuous reception (DRX) cycle. A category of at least one subframe of the radio frame that is likely to be encountered during the period of activity is determined, if a dynamic reconfiguration of time division duplex (TDD) uplink (UL)—downlink (DL) configurations is enabled. The category of the least one subframe includes one of a flexible subframe and a fixed subframe.
Abstract:
A method for performing a data session via a Wi-Fi access of a user equipment (UE) in a cellular network is provided. The method includes maintaining a look-up table including at least an entry, the entry including a Wi-Fi identifier of a Wi-Fi access point (AP) and location information of the Wi-Fi AP, determining whether a user preference for a Wi-Fi connection is set to ON or OFF, checking whether at least one matched entry of the look-up table is found based on current location information of the UE, scanning to discover the Wi-Fi AP, connecting to a Wi-Fi AP corresponding to the matched entry based on a result of the determining, and performing a data session via a Wi-Fi access to the connected Wi-Fi AP.

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 dormant/idle mode operation of a plurality of cellular device(s) is offloaded using proximity radio interface to a second device having cellular capability so that a plurality of cellular devices can turn off the radio and baseband circuitry associated with the cellular capability, and save battery power. The second device to which the dormant/idle mode operation is offloaded acts like a proxy device for a plurality of cellular devices to perform at least one of the following functions on behalf of plurality of cellular devices: monitor network page, perform cell re-selection, perform tracking area update, or perform D2D transmission and reception, wherein the second device and the plurality of cellular devices are connected each other through a proximity radio interface.
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.
