MOBILE COMMUNICATION SYSTEM, SGW, TERMINAL, METHOD OF RECEPTION OF MOBILE COMMUNICATION SYSTEM, METHOD OF RECEPTION OF SGW AND METHOD OF RECEPTION OF TERMINAL Russian patent published in 2017 - IPC H04W36/12 

FIELD: radio engineering, communication.

SUBSTANCE: mobile communication system includes UE (45), MME (25), SGSN (27), and SGW (15). The SGW (15) turns the tool on in order that when the ISR (signaling reduction in the sleep mode) is active in UE (45), MME (25), SGSN (27), and SGW (15) to send the data notification message of the descending communication line to MME (25) and SGSN (27), and when the message of inquiry for modification of one-way channel is accepted from another MME (35) or another SGSN (37) different from the mentioned MME (25) and SGSN (27), resend the data notification message of the descending communication line only to another MME (35) or another SGSN (37) which has sent the message of inquiry for modification of one-way channel.

EFFECT: ensure a reliable reception of data batch of the descending communication line that is sent during the movement of the UE facility.
