Technical field

The present disclosure relates to the field of communications, and in particular, to a bearer configuration determination, an information transmission method and apparatus, a primary base station, and a secondary base station.

Background technique

In a 5G network, there will be three types of base stations: a next-generation base station (gNB), an enhanced long-term evolution base station (eLTE eNB), and a long-term evolution base station (LTE eNB), and the gNB is a 5G base station connected to the core network 5GC through the NG interface ( 5G Core Network, the 5th generation core network), the LTE eNB is a 4G base station connected to the core network EPC (Evolved Packet Core, Evolved Packet Core) through the S1 interface, and the eLTE eNB is a 4G to 5G transition base station can be connected at the same time. Go to the core network EPC (via the S1 interface) and 5GC (via the NG interface). The connection interface between the LTE eNB base stations is called the X2 interface, and the connection interface between the gNB base stations is called the Xn interface, and the eLTE eNB base station can play the role of the LTE eNB base station and the role of the gNB base station.

In the Long Term Evolution (LTE) system, data flows with the same Quality of Service (QoS) requirements are aggregated into bearers, and QoS processing by the base station and the core network is performed by bearer. In the 5G system, a new QoS mechanism will be adopted to support enhanced mobile broadband (eMBB), massive machine type communication (MMTC), and high-reliability low-latency communication (Ultra Reliable and Low Latency Communication (URLLC) and other 5G features.

In the new 5G QoS mechanism, a User Equipment (UE) can be configured with multiple Protocol Data Unit Sessions (PDU Sessions), and a PDU Session can contain multiple Quality of Service flows (Quality). Of Service Flow (referred to as QoS Flow). The QoS flows of the same PDU session can be mapped to the same data radio bearer (DRB). The QoS flows of different PDU sessions cannot be mapped to the same DRB.

When a dual connectivity (DC) operation is performed in a 5G network, part of the PDU Session of one UE and/or part of the QoS Flow in the PDU Session may be offloaded from the primary base station to the secondary base station. The flow that is split to the secondary base station can be mapped to the MCG split bearer (Master Cell Group split bearer), the SCG bearer (Secondary Cell Group bearer), or the SCG split bearer (Secondary Cell Group split bearer). The secondary cell group separates the bearer). The data on the SCG bearer flows from the secondary base station to the UE. The data part on the SCG split bearer flows from the secondary base station to the UE, and the secondary base station flows to the UE through the primary base station.
