Google patents faster data handoff for phones in standby mode

Patent drawing
Patent drawing from the official filing.

This filing describes a method for phones to send small amounts of data while in a low-power standby mode, without fully waking up the connection to the network. It uses a specific identifier to keep the data transfer going even as the network verifies the phone's identity in the background.

Why it mattersIt could help reduce battery drain and improve responsiveness for background tasks like notifications or small updates on mobile devices.

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, from the RAN, a first cell radio network temporary identifier (C-RNTI); and while the UE is operating in an inactive state: performing EDT with the RAN using the first C-RNTI; performing a random access procedure during the EDT, including receiving, from the RAN, a second C-RNTI; and after the receiving of the second C-RNTI, continuing to perform the EDT using the first C-RNTI.
