Verizon Communications. has been granted a patent for an enhanced discontinuous reception (DRX) mechanism. The method involves receiving a connection request from user equipment, identifying a group identifier, determining a DRX parameter based on this identifier, and transmitting the parameter back to the user equipment.

Improved discontinuous reception mechanism for cellular network attachment
The patent US12048049B2 outlines a method for managing user equipment (UE) connections to a cellular network. The process begins with receiving a request from the UE to attach to the network. A group identifier is then identified based on the UE's identity, which includes a Subscriber Profile Identifier (SPID) for non-standalone mode and a Single Network Slice Selection Assistance Information (S-NSSAI) for standalone mode. Notably, this group identifier remains consistent across both modes. Following this, a discontinuous reception (DRX) parameter is determined based on the group identifier and transmitted back to the UE. The method also allows for the inclusion of a Quality of Service (QoS) Class Identifier (QCI) value, which can further refine the DRX parameter.
Additionally, the patent describes a non-transitory computer-readable storage medium and a device that implements the aforementioned method. The device is equipped with a processor that performs the same functions: receiving attachment requests, identifying group identifiers, determining DRX parameters, and transmitting these parameters to the UE. The claims specify that the DRX parameters can include both idle-mode and connected-mode configurations, and the identification of the group identifier may involve mapping a unique identifier of the UE. This innovation aims to enhance the efficiency and effectiveness of cellular network connections, particularly in varying operational modes.
