DISPLAYING PDN AND PDU SESSION TYPE AND DETECTING CAPABILITY Russian patent published in 2020 - IPC H04W36/00 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to wireless communication. AMF is configured to exchange signals with a session control function object and a control plane packet data network gateway, PDN, SMF and PGW-C, wherein the AMF is configured to perform steps of sending a SMF and PGW-C request to provide a session management context, SM, which also includes the displayed bearers of the EPS bearer; wherein for PDU sessions with PDU "Ethernet" or "unstructured" session type, enabling the ability of the target MME to support the PDN type "without IP" to the PGW-C and SMF objects in the request to enable the PGW-C and the SMF to determine whether to encapsulate the carrier-side context of the PDN bearer type "without IP"; request is transmitted to SMF.

EFFECT: technical result is to provide handover from system 5G, 5GS, to improved packet communication system, EPS, wherein interface is provided between mobility management entity, MME, EPS and access and mobility management function (AMF).
