Google patents way for phones to keep getting group data while idle

Patent drawing
Patent drawing from the official filing.

This filing describes a method for mobile devices to receive group data broadcasts while in a low-power 'inactive' state. It allows the phone to maintain a specific data channel for these broadcasts without fully waking up to a connected state. When the phone does switch to full connection, it releases this specific channel to save resources.

Why it mattersThis could help phones use less battery while still receiving important group updates like emergency alerts or shared media streams.

In the filing’s own words

A method for receiving multicast and/or broadcast services (MBS) data can be implemented in a user equipment (UE). The method can include receiving ( 1436), from a radio access network (RAN), first MBS data in a connected state of a protocol for controlling radio resources. The method can include receiving ( 1454), from the RAN, multicast configuration for an inactive state of the protocol. The method can still further include receiving ( 1463) second MBS data in the inactive state, in accordance with the multicast configuration for the inactive state. Other apparatuses and methods are described.

What exactly they claim (claim 1)

1. A method for receiving multicast and/or broadcast services (MBS) data, the method implemented in a user equipment (UE) and comprising: receiving, from a radio access network (RAN), MBS data in an inactive state of a protocol for controlling radio resources and via an inactive state multicast radio bearer (MRB); in response to transitioning from the inactive state to a connected state, releasing the inactive state MRB.
