  • Publication number: 20190372929
    Abstract: Embodiments described herein relate to managing bearers in a radio access network (e.g., next generation RAN (NG-RAN), etc.). In one example, a central-unit control-plane (CU-CP) communicates with a distributed unit (DU) and a CU-UP to exchange transport network layer addresses (TNLAs) and tunnel endpoint identifiers (TEIDs) between the DU and the CU-UP. In this way, the DU becomes resistant to the CU-UP's rejection of a bearer setup request from the CU-CP during a bearer setup procedure. Furthermore, during virtual machine (VM) migration or local problems of the CU-UP, an E1 procedure known as “bearer relocate” can be defined to notify the DU of a new TNLA for one or more affected general packet radio service tunneling protocol (GTP) tunnels that are affected by the VM migration or local problems.

  • Publication number: 20190246310
    Abstract: Systems and methods of providing feedback when a specific PDU is successfully delivered or transmitted are described. The node hosting PDCP entity indicates triggering of a DDDS frame from the remote corresponding node. Rather than immediately triggering transmission of a DDDS frame, the node hosting PDCP entity indicates triggering based on successful delivery of a PDU having a specific SN, as long as in-sequence delivery or transmission of PDUs up to the specific SN was successful. The DDDS frame is transmitted once the corresponding node determines that the PDU having the SN was successfully delivered or transmitted. After reporting by the DDDS frame, the QoS flow associated with the PDUs is remapped from a source DRB to a target DRB.
