==MULTI-ACCESS PDU SESSIONS FOR MULTI-USIM DEVICES - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17454230 titled 'MULTI-ACCESS PDU SESSIONS FOR MULTI-USIM DEVICES

==Simplified Explanation==

The abstract describes a patent application that introduces aspects allowing a Multi-USIM (MUSIM) device to establish a Multi-Access (MA) Packet Data Unit (PDU) session over two different Public Land Mobile Networks (PLMNs) associated with respective Universal Subscriber Identity Modules (USIMs).

* The MUSIM device sends a registration request to a base station of the first PLMN, indicating its capability for an MA PDU session.
* The MA PDU session consists of multiple PDU sessions related to a single access type.
* The MUSIM device then sends a PDU session establishment request for the first PDU session in the first PLMN and the second PDU session in the second PLMN.
* The first PLMN is associated with the first USIM of the MUSIM device, while the second PLMN is associated with the second USIM.
* This allows the establishment of MA PDU sessions associated with MUSIM devices.

== Potential Applications ==
* This technology can be applied in scenarios where a device needs to establish an MA PDU session over multiple PLMNs associated with different USIMs.
* It can be useful in situations where seamless connectivity is required across different networks.

== Problems Solved ==
* The technology solves the problem of establishing an MA PDU session over multiple PLMNs associated with different USIMs in a MUSIM device.
* It addresses the challenge of maintaining connectivity and session establishment across different networks.

== Benefits ==
* The technology enables MUSIM devices to establish MA PDU sessions over multiple PLMNs, enhancing connectivity options.
* It provides flexibility for devices to utilize different networks simultaneously, improving network coverage and reliability.


==Original Abstract Submitted==

Aspects are provided which allow an MA PDU session to establish over two 3GPP accesses respectively via different PLMNs associated with respective USIMs of a MUSIM device. During registration, the MUSIM UE may transmit a registration request to a base station of a first PLMN indicating a UE capability for a MA PDU session associated with a MUSIM device. The MA PDU session includes a plurality of PDU sessions associated with a single access type. Afterwards, the UE may transmit a PDU session establishment request for a first PDU session of the PDU sessions in the first PLMN and for a second PDU session of the PDU sessions in a second PLMN, where the first PLMN is associated with a first USIM of the UE, and the second PLMN is associated with a second USIM of the UE. Consequently, MA PDU sessions associated with MUSIM devices may be established.
