Samsung patents method for managing IoT data connections during mode switches
This patent describes a way for low-power IoT devices to manage their data connections when switching between different network modes. When a device changes from a wideband to a narrowband mode, it automatically pauses specific data channels and updates the network to reflect this change.
In the filing’s own words
Disclosed is a method of managing PDU session inter-working in a User Equipment, UE, wherein if the UE changes from WB-N1 mode to NB-S1 mode, then the UE sets the state of any dedicated EPS bearer context to be inactive.
What exactly they claim (claim 1)
1. A method performed by a User Equipment (UE) in a wireless communication system, the method comprising: changing a mode of the UE operating in a single registration mode from a WB-N1 mode to an NB-S1 mode in an idle mode; upon changing the mode of the UE operating in the single registration mode from the WB-N1 mode to the NB-S1 mode in the idle mode, setting a state of a dedicated evolved packet system (EPS) bearer context to be inactive; after setting the state of the dedicated EPS bearer context to be inactive, including an EPS bearer context status information element (IE) in a tracking area update (TAU) request message; and upon changing the mode of the UE operating in the single registration mode from the WB-N1 mode to the NB-S1 mode in the idle mode, locally deactivating a dedicated EPS bearer.
