MULTICAST-BROADCAST SERVICES MOBILITY AND SERVICE CONTINUITY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18249760 titled 'MULTICAST-BROADCAST SERVICES MOBILITY AND SERVICE CONTINUITY
Simplified Explanation
- The patent application is about technology that allows for the continuity of Multicast/Broadcast Service (MBS) across different cells in a wireless network. - When a user equipment (UE) is in idle or inactive mode, it can receive MBS assistance information that includes scheduling information for MBS reception windows. This helps the UE evaluate and select the appropriate cell to connect to. - When a UE is in connected mode, it can conduct quality measurements for MBS and report them to the network. The network can then reconfigure the UE with an MBS configuration for a target cell. If there are differences in MBS transmission progress between the source cell and the target cell, the UE can recover lost MBS data or delete duplicate data accordingly. - The network apparatus, such as a gNB (gNodeB), can map a GPRS Tunneling Protocol Sequence Number of an MBS data unit to a Packet Data Convergence Protocol Sequence Number in a target cell. This helps in determining the MBS configuration to be used by a UE requesting a handover.
Original Abstract Submitted
Wireless User Equipment, UE, and network apparatuses may be adapted to facilitate continuity of Multicast/Broadcast Service, MBS, across cells. A UE in idle/inactive mode, for example, may receive MBS assistance information comprising scheduling information defining MB S reception windows and perform a cell re selection evaluation process accordingly. An UE in connected mode may conduct and report MB S quality measurements and receive an RRC reconfiguration comprising an MB S configuration for a target cell, determine that MBS transmission progress differs between the source cell and the target cell, and recover lost MBS PDUs or delete duplicate MBS PDUs accordingly. A network apparatus, such as a gNB for example, may map a GPRS Tunneling Protocol Sequence Number of an MBS PDU, to a Packet Data Convergence Protocol Sequence Number in a target cell, and determine an MB S configuration for use by a UE requesting a handover accordingly.
