UNICAST-MULTICAST CONVERSION METHOD AND DEVICE, AND PROCESSOR READABLE STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18020052 titled 'UNICAST-MULTICAST CONVERSION METHOD AND DEVICE, AND PROCESSOR READABLE STORAGE MEDIUM

Simplified Explanation

The present application describes a method and apparatus for converting unicast to multicast, involving receiving a Radio Resource Control (RRC) reconfiguration message, reconstructing an MBMS Packet Data Convergence Protocol (PDCP) entity, sending a reconfiguration completion message, and receiving MBMS service data packets through a unicast bearer.

• Receiving RRC reconfiguration message from first network node
• Reconstructing MBMS PDCP entity according to the message
• Sending reconfiguration completion message to convert multicast bearer to unicast bearer
• Receiving MBMS service data packets through unicast bearer

Original Abstract Submitted

Embodiments of the present application provide a unicast multicast conversion method and apparatus, and a processor-readable storage medium, wherein the unicast multicast conversion method comprises: receiving a Radio Resource Control (RRC) reconfiguration message sent by a first network node, when Multimedia Broadcast Multicast Service (MBMS) service data packets sent by the first network node are received through a multicast bearer and a User Equipment (UE) is in a connected state; reconstructing an MBMS Packet Data Convergence Protocol (MBMS PDCP) entity according to the RRC reconfiguration message; sending a reconfiguration completion message to the first network node so that the first network node converts the multicast bearer to a unicast bearer and sends the MBMS service data packets to the UE through the unicast bearer, the reconfiguration completion message being configured to characterize that reconstruction of the MBMS PDCP entity is accomplished by the UE; and receiving the MBMS service data packets sent by the first network node through the unicast bearer. The method realizes the conversion of the UE from receiving the MBMS service data packets through the multicast bearer to receiving the MBMS service data packets through the unicast bearer, thereby ensuring that no data packets are lost.
