MOBILE COMMUNICATION SYSTEM, MME, METHOD OF MOBILE COMMUNICATION SYSTEM INCOMING CALLS CONTROL AND MME INCOMING CALLS CONTROL METHOD Russian patent published in 2017 - IPC H04W48/00 H04W60/00 

FIELD: communication.

SUBSTANCE: invention relates to communication. For this purpose the UE has the means of: supporting access to the eNB and the control radio device 2G/3G; to perform handover from the LTE wireless communication to a 3G wireless communication area or a 2G wireless communication area; and reception if the service handover procedure is performed, when the MME receives a request message of paging via the SGs-interface between the MME and the MSC/VLR (mobile switching centre/visitor location register) from the MSC/VLR and the MME discards the paging message and does not perform further actions, a request message of paging repeatedly transmitted by the MSC/VLR.

EFFECT: technical result is providing a movement control device, which, even when the ISR (idle state reduction of service signals transmission volume) is active, allows proper notification of the UE relative to the incoming voice call formed when the mobile communication device moves from the recording position area controlled by the MME (mobility management entity), to the recording position area controlled by the SGSN.
