Google patents faster data handoff for phones in standby mode

This patent describes a method for phones to send small amounts of data while in a low-power standby mode without fully waking up. It uses a specific identifier to handle the data exchange, allowing the device to stay in an energy-saving state while communicating with the network.

Why it mattersThis could help phones save battery by handling quick data tasks without switching to a high-power connected state.

In the filing’s own words

A distributed unit (DU) of a distributed base station, where the distributed base station that includes the DU and a central unit (CU), can perform a method for managing early data transmission (EDT) with a user equipment (UE). The method includes: performing ( 1402), while a radio connection between the UE and the DU is not active, a random access procedure, including receiving, from the UE, an uplink message formatted in accordance with a protocol for controlling radio resources; sending ( 1404), to the CU, a DU-to-CU message including the uplink message; receiving ( 1406), from the CU, a CU-to-DU message when a validity of the uplink message has been verified; generating ( 1408) a contention resolution ID for the UE; and transmitting ( 1410), to the UE, the contention resolution ID for EDT without transitioning the UE to a connected state.

What exactly they claim (claim 1)

1. A method performed by a user equipment (UE) for managing early data transmission (EDT) with a radio access network (RAN), the method comprising: receiving, by the UE and from the RAN, a first temporary cell radio network temporary identifier (C-RNTI); and while the UE is operating in an inactive state: performing, by the UE, EDT with the RAN using the first temporary C-RNTI; performing, by the UE, a random access procedure during the EDT, including receiving, from the RAN, a second temporary C-RNTI; and after the receiving of the second temporary C-RNTI, continuing, by the UE, to perform the EDT using the first temporary C-RNTI.
