Samsung patents method for managing 5G data requests on non-cellular networks

Patent drawing
Patent drawing from the official filing.

Samsung has been granted a patent for a method that helps mobile devices manage data connections when switching between standard cellular networks and non-3GPP access points. The system uses a specific timer to delay data requests until the device confirms it is in a valid service area, preventing unnecessary network traffic.

Why it mattersThis improves how phones handle background data updates when moving between different types of network connections, ensuring smoother service without overloading the network.

In the filing’s own words

For receiving downlink data packets over Non-Third Generation Partnership Project (N3GPP) access, a User Equipment (UE) is configured to manage the triggering of Service Request procedures for receiving N3GPP Mobile Terminating (MT) packets in a coverage area of N3GPP access from a 5th Generation (5G) network. A Service Request procedure is triggered by the UE if the UE detects that the UE is in the coverage area of N3GPP access and that the UE is in 5th Generation Mobility Management (5GMM)-IDLE mode over N3GPP access and the back-off timer has expired. The detection is based on the UE determining that an access stratum connection is established between the UE and the 5G network over N3GPP access.

What exactly they claim (claim 1)

1. A method of a user equipment (UE), the method comprising: identifying that the UE is in idle mode over non-3rd generation partnership project (non-3GPP) access and out of a service area of the non-3GPP access; transmitting, to an access and mobility function (AMF), a first service request message over a 3GPP access; receiving, from the AMF, a service reject message in response to the first service request message over the 3GPP access, the service reject message including first information for a T3346 timer; starting the T3346 timer based on the first information for the T3346 timer; receiving, from lower layers of the non-3GPP access, an indication indicating that an access stratum connection has been established between the UE and a network; identifying that the T3346 timer is expired; and in response to initiating a service request procedure based on the UE being in idle mode but present in the service area of the non-3GPP access, the indication, and the T3346 timer being expired, transmitting, to the AMF, a second service request message over the non-3GPP access, wherein the UE is registered with same public land mobile network (PLMN) over both the 3GPP access and the non-3GPP access, the T3346 timer is applied to both the 3GPP access and the non-3GPP access.
