COMMUNICATION SYSTEM Russian patent published in 2021 - IPC H04W68/00 H04W36/02 

FIELD: communication.

SUBSTANCE: disclosed is a communication system in which a base anchor station receives downlink data from a core network node for a communication device. Base station attempts (e.g. by RAN-based paging) to initiate communication with the communication device, and when the communication device does not respond to an attempt to initiate communication, base station sends a message to a core network node requesting initiation of a paging procedure for a communication device (e.g., paging based on S1).

EFFECT: technical result is achieving such capabilities, while allowing mobile devices to maintain easy (weak) connection to network (LC-mode), as: possibility of informing a mobility management entity (MME) that certain operations, such as load balancing, required tracking area update (TAU), power saving mode (PSM), rollback with channel switching (CSFB) with mobile termination (MT) may be affected by the LC operation of the mobile device; and possibility of notifying MME when mobile device enters LC state.
