Description
Technical Field
The present invention relates to communications technologies, and in particular, to a method and an apparatus for establishing a redundant path for 5G data transmission, and a computer-readable storage medium.
Background
In order to support the 5G high-reliability low-latency capability, in the existing 5G research report, for a high-reliability service, in the PDU Session establishment or the PDU Session modification process, a Policy Control Function (PCF) on the core network side determines whether to instruct a Session Management Function (SMF) to establish a redundant transmission path based on a 5QI QoS service flow. As shown in fig. 1, if a redundant path needs to be established, the SMF selects a new User Plane Function (UPF), establishes an N4 session, and sends core network tunnel information to the radio access network NG-RAN through the N2 SM. In the subsequent process, the NG-RAN needs to notify Tunnel information at the Radio Access Network (RAN) side of AN Tunnel Info to the UPF through the SMF, so that the redundant path is successfully established.
In the existing solution, during the PDU session establishment or PDU session modification process, the PCF on the core network side determines whether a redundant transmission path is established for the QoS traffic based on 5 QI. However, the NG-RAN is a main node and a key link of a high-reliability low-delay service, and therefore, for the conditions of radio resource capacity, 5QI service satisfaction degree and the like, the NG-RAN should also participate in judging whether to establish a redundant transmission path, and there is no method for the NG-RAN to determine whether to request the 5G core network to establish the redundant transmission path.
