US 11,641,680 B2 · Methods and systems for handling user equipment associated information

Abstract

Methods and systems for handling UE associated information in non-terrestrial networks are disclosed. In one embodiment, a method performed by a satellite head station, includes: translating a first uplink (UL) tunnel address associated with a core network to a second UL tunnel address associated with the satellite head station, wherein the first and second UL tunnel addresses are each associated with a packet data unit (PDU) session established between the core network and a user equipment device (UE); transmitting the second UL tunnel address to a first satellite base station; and receiving UL data associated with the PDU session from the first satellite base station, wherein a UL tunnel address destination associated with the received UL data is set as the second UL tunnel address.

Dependent claims

A method performed by a satellite head station, the method comprising:

translating a first uplink (UL) tunnel address associated with a core network to a second UL tunnel address associated with the satellite head station, wherein the first and second UL tunnel addresses are each associated with a packet data unit (PDU) session established between the core network and a user equipment device (UE);
transmitting the second UL tunnel address to a first satellite base station;
and
receiving UL data associated with the PDU session from the first satellite base station, wherein a UL tunnel address destination associated with the received UL data is set as the second UL tunnel address.

1 more element

A satellite head station, comprising:

at least one processor configured to translate a first uplink (UL) tunnel address associated with a core network to a second UL tunnel address associated with the satellite head station, wherein the first and second UL tunnel addresses are each associated with a packet data unit (PDU) session established between the core network and a user equipment device (UE);
and
a transceiver, coupled to the at least one processor, and configured to transmit the second UL tunnel address to a first satellite base station, and receive UL data associated with the PDU session from the first satellite base station, wherein the received UL data has a UL tunnel address destination set as the second UL tunnel address.

A satellite head station, comprising:

a transceiver configured to receiving UE context information from a first satellite base station during a first time period, wherein the UE context information is associated with a UE that is located within a first geographic cell of the first satellite base station and is in an inactive state;
a memory for storing the UE context information;
and
at least one processor configured to translate a first downlink (DL) tunnel address associated with a first satellite base station to a second DL tunnel address associated with the satellite head station, wherein the first and second DL tunnel addresses are each associated with a packet data unit (PDU) session, and
wherein the transceiver is further configured to transmit the second DL tunnel address to a core network, wherein DL data associated with the PDU session is transmitted from the core network with a DL tunnel address destination set as the second DL tunnel address.
