Handling of Session Context - A simplified explanation of the abstract
This abstract first appeared for US patent application 18743199 titled 'Handling of Session Context
Simplified Explanation
The patent application describes a method to transfer the management responsibility of PDU sessions between wireless devices and data networks without causing interruptions in the sessions.
Key Features and Innovation
- PDU sessions between wireless devices and data networks are managed by SMFs in the network.
- UPFs in the network handle the user planes of these PDU sessions.
- When transferring management of a PDU session from one SMF to another, a control element is included in the release message to the UPF to indicate the upcoming re-establishment of the signaling session by the second SMF.
- This method ensures a smooth transfer of management responsibility without disrupting the PDU session.
Potential Applications
This technology can be applied in various wireless communication networks to facilitate the seamless transfer of management responsibility for PDU sessions.
Problems Solved
This technology addresses the issue of interruptions in PDU sessions when transferring management responsibility between SMFs in a network.
Benefits
The benefits of this technology include uninterrupted PDU sessions during the transfer of management responsibility, ensuring a seamless user experience.
Commercial Applications
- Telecommunication companies can use this technology to improve the efficiency of managing PDU sessions in their networks.
- Network equipment manufacturers can incorporate this innovation into their products to enhance the reliability of wireless communication networks.

Original Abstract Submitted
A network provides PDU sessions between wireless devices and data networks. UPFs in the network handle the user planes of these PDU sessions, while SMFs in the network manage the PDU sessions. The SMFs have dedicated interfaces for signaling sessions to the UPFs. In the occasion that managing of a PDU session has to be transferred from one SMF to another SMF, the first SMF has to release the signalling session with the UPF for the PDU session, and a second SMF has to re-establish the signaling session with the UPF for the same PDU session. To avoid that during the transfer of the management responsibility transfer the wireless device experiences a hick-up in the PDU session the first SMS includes a control element in the release message to the UPF, indicating to the UPF that the signaling session for the PDU session will be re-established by a second SMF, and that the UPF shall continue the handling of the PDU session till re-establishment.
