Abstract
Embodiments of the invention include a User Plane Core Network entity such as UPGW, capable of interfacing with at least one RAN node via a User Plane interface such as NG3 interface, said User Plane Core Network entity configured to: —support data transfer for a UE session in a mode referred to as connectionless mode not requiring setup of a connection with a RAN node for said data transfer, —support paging request over User Plane, for DL data transfer for said UE session in connectionless mode.
Claims24
An apparatus comprising
- at least one processor;
- and
- at least one memory including computer program code,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
- provide functions of a user plane core network entity interfacing with at least one radio access network node via a user plane interface,
- support data transfer for a user equipment session in a mode referred to as a connectionless mode not requiring setup of a connection with a radio access network node for said data transfer,
- support paging over a user plane, for downlink data transfer for said user equipment session in the connectionless mode, and
- upon reception of downlink data for said user equipment session in the connectionless mode, in a state referred to as a connectionless idle state where paging is required, send over said user plane interface to at least one radio access network node through which to page the user equipment, a downlink dummy packet indicating a paging request.

An apparatus comprising
- at least one processor;
- and
- at least one memory including computer program code,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
- provide functions of a control plane core network entity interfacing with a user plane core network entity, said control plane core network entity serving a user equipment, said user plane core network entity interfacing with at least one radio access network node via a user plane interface, said user plane core network entity supporting data transfer for a session for the user equipment in a mode referred to as a connectionless mode not requiring setup of a connection with a radio access network node for said data transfer, said user plane core network entity supporting paging over a user plane, for downlink data transfer for said user equipment session in the connectionless mode, in a state referred to as a connectionless idle state where paging is required, and
- provide to said user plane core network entity information for said paging of said user equipment over the user plane, wherein said paging over the user plane comprises sending a downlink dummy packet indicating a paging request.

A method comprising:
- supporting data transfer for a user equipment session in a mode referred to as a connectionless mode not requiring setup of a connection between a user plane core network entity and a radio access network node for said data transfer,
- supporting paging over a user plane, for downlink data transfer for said user equipment session in the connectionless mode and in a state referred to as a connectionless idle state where paging is required;
- and
- upon reception from the user plane core network entity, over said user plane interface, of a downlink dummy packet indicating a paging request, paging the user equipment.
