MULTI-USIM DEVICE ACCESSING SERVICES OF A SECOND CELLULAR NETWORK THROUGH A FIRST CELLULAR NETWORK VIA A GATEWAY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18011497 titled 'MULTI-USIM DEVICE ACCESSING SERVICES OF A SECOND CELLULAR NETWORK THROUGH A FIRST CELLULAR NETWORK VIA A GATEWAY

Simplified Explanation

The patent application describes a user device (UE) that has two universal subscriber identity modules (USIMs) for connecting to two different cellular networks.

  • The first cellular network has a first radio access network (RAN) and the second cellular network has a second RAN.
  • The UE determines if the first cellular network allows access to the gateway of the second cellular network.
  • If access is allowed, the UE connects to the second cellular network through the first RAN and the gateway.
  • The UE also prevents the second cellular network from sending information to the UE through the second RAN.


Original Abstract Submitted

A user device (UE) equipped with a first universal subscriber identity module (USIM) for communicating with a first cellular network and a second USIM for communicating with a second cellular network, wherein the first cellular network includes a first radio access network (RAN) and the second cellular network includes a second RAN, determines whether the first cellular network supports access to a gateway of the second cellular network (), and when the first cellular network supports the access: (i) connects to the second cellular network via the first RAN and the gateway (), and (ii) prevents the second cellular network from transmitting information to the UE via the second RAN ().
