Among the companies innovating in LTE discontinuous reception (DRX), Intel is one of the leading patents filers. The company’s patent pertains to legally intercepting a proximity service, such as device-to-device (D2D) communication, provided to user equipment (UEs). For instance, a method involves an evolved Node B (eNB) sending a proximity service setup message to a first UE to establish D2D communication with a second UE. Subsequently, the eNB transmits a lawful interception message to either the first UE or the second UE to facilitate legal interception of the D2D communication. The eNB then receives packets related to the D2D communication from the first UE or the second UE and conveys these received packets from both UEs to the core network (CN) for duplication. Other prominent patent filers in the space include Qualcomm and Apple

In terms of application diversity, Intel leads the pack, while Apple and Ofinno Technologies stood in second and third positions, respectively. By means of geographic reach, Sun Patent Trust held the top position, followed by Intel and InterDigital.                    

 LTE discontinuous reception (DRX) plays a crucial role in power efficiency within 5G technology. By allowing user devices to periodically enter a low-power sleep mode when there is no data transmission, it significantly extends battery life, making it especially important for IoT devices and mobile devices striving for optimal power management.
