US 12,598,655 B2 · Method and apparatus for managing session by considering backhaul information in wireless communication system

Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method by which an access network (AN) node of a wireless communication system manages a session by using backhaul information, according to one embodiment of the present disclosure, may comprise the steps of: selecting an access and mobility management function (AMF) when a registration request message is received from a user equipment (UE); selecting one transport network layer association (TNLA) from among candidate TNLAs for the selected AMF by considering the type of backhaul network of a control plane; transmitting an initial UE message to the selected AMF by using the selected TNLA; and performing a registration procedure of the UE when a selected TNLA response signal is received from the selected AMF, wherein the candidate TNLA can include a low earth orbit (LEO) and/or a geosynchronous earth orbit (GEP).

Dependent claims

A session management method performed by an access network (AN) node of a wireless communication system using backhaul information, the method comprising:

selecting an access and mobility management function (AMF)upon receiving a registration request message from a user equipment (UE);
selecting one transport network layer association (TNLA) from candidate TNLAs for the selected AMF based on a type of a backhaul network of a control plane being associated to the TNLA;
transmitting an initial UE message to the selected AMF based on the selected TNLA;
and
performing a registration procedure of the UE in case that a selected TNLA response signal is received from the selected AMF,
wherein the type of the backhaul network is at least one of low earth orbits (LEO) and a geosynchronous earth orbit (GEO).

3 more elements

An access network (AN)node device for managing a session using backhaul information in a wireless communication system, the device comprising:

a transceiver configured to communicate with a specific node of the wireless communication system and communicate with a user equipment (UE);
a memory configured to store session related instructions;
and
at least one processor configured to execute the session related instructions to cause the AN node device to:
select an access and mobility management function (AMF) upon receiving a registration request message from the UE through the transceiver,
select one transport network layer association (TNLA) from candidate TNLAs for the selected AMF based on a type of a backhaul network of a control plane being associated to the TNLA,
transmit an initial UE message to the selected AMF based on the selected TNLA through the transceiver, and
perform a registration procedure of the UE in case that a selected TNLA response signal is received from the selected AMF,
wherein the type of the backhaul network is at least one of low earth orbits (LEO) and a geosynchronous earth orbit (GEO).
