Samsung patents method for phones to keep receiving group broadcasts while moving

This filing describes how a phone can continue receiving group data broadcasts, such as emergency alerts or live video, while moving between cell towers. The phone uses specific instructions from the network to decide whether to stay in a low-power "inactive" mode or switch to a fully connected state to maintain the stream.

Why it mattersIt helps ensure that group messaging services remain reliable for users who are walking or driving, rather than dropping the connection when they move to a new area.

In the filing’s own words

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. <u style=“single”>Embodiments herein disclose methods for handling multicast reception in network ( 1000) by UE ( 100). The method includes determining multicast reception to be received in RRC inactive state, while UE is in mobility scenario. Further, the method includes receiving a message to support mobility scenario of UE in RRC INACTIVE state from network device ( 200). Further, the method includes handling the multicast reception of UE in the mobility scenario based on the message.

What exactly they claim (claim 1)

1. A method performed by a user equipment (UE) in a communication system, the method comprising: receiving a radio resource control (RRC) release message including suspend configuration information and frequency information associated with cell reselection; performing, in an RRC inactive state, the cell reselection based on the frequency information, wherein the UE is configured to receive data associated with multicast broadcast service (MBS) multicast in the RRC inactive state; and receiving the data associated with MBS multicast in the RRC inactive state or in an RRC connected state, wherein, in case that configuration information associated with the MBS multicast is unavailable in the reselected cell, the data associated with MBS multicast is received in the RRC connected state, and wherein, in case that the configuration information is available in the reselected cell, the data associated with MBS multicast is received in the RRC inactive state.
