Samsung patents method for managing group data in 5G networks
This patent describes a method for 5G base stations to handle data sent to multiple users at once, known as multicast. The system coordinates between the core network and the base station's internal components to set up the data stream efficiently.
In the filing’s own words
A method and device for transmitting data in a wireless communication network are provided. The method includes: receiving a first multicast session start request message including an identification of a packet data unit (PDU) session corresponding to a multicast service and information on a multicast group from a core network; transmitting a second multicast session start request message including the information on the multicast group to a distribution unit (DU) of the access network; receiving a second multicast session start response message in response to the second multicast session start request message from the DU of the access network; and transmitting a first multicast session start response message to the core network in response to the first multicast session start request message.
What exactly they claim (claim 1)
1. A method for transmitting data in a wireless communication system by a anew generation-radio access network (NG-RAN) node, the method comprising: receiving, from a core network (CN), a first request message including an identifier (ID) of a packet data unit (PDU) session and an ID related to a multicast service; transmitting, to the CN, a second request message indicating, to the CN, to use a multicast for the multicast service; and transmitting, from a central unit-control plane (CU-CP) of the NG-RAN node to a distribution unit (DU) of the NG-RAN node, a third request message including the ID related to the multicast service, information about a radio data bearer configuration, and information about an area for the multicast service.
