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.
