具体实施方式detailed description
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
第三代合作计划(3rd Generation Partnership Project，3GPP)提出Option3架构，在Option3架构中，使用4G核心网进行数据传输，终端通过LTE接入并通过DC技术使用5G的空口资源，双连接技术将Option3架构定义为ENDC(演进通用陆地无线电接入-新空口(Evolved-Universal Terrestrial Radio Access-New Radion，E-UTRA-NR)Dual Connectivity)，ENDC需要依托LTE网络来为终端提供服务。这种5G不能独立提供端到端服务，而需要依托LTE网络来提供服务的网络架构，统称为非独立架构(Non-standalone architecture，NSA)网络。在一实施例中，本申请实施例中描述的终端或用户设备(User Equipment，UE)，指的是支持NSA架构和ENDC功能的终端。以下对本申请实施例的相关技术进行说明。The 3rd Generation Partnership Project (3GPP) proposes the Option3 architecture. In the Option3 architecture, the 4G core network is used for data transmission. The terminal accesses through LTE and uses 5G air interface resources through DC technology. The architecture is defined as ENDC (Evolved-Universal Terrestrial Radio Access-New Radio (E-UTRA-NR) Dual Connectivity). ENDC needs to rely on the LTE network to provide services for terminals. This kind of 5G cannot independently provide end-to-end services, but the network architecture that needs to rely on the LTE network to provide services is collectively referred to as a non-standalone architecture (NSA) network. In an embodiment, the terminal or user equipment (User Equipment (UE)) described in the embodiments of the present application refers to a terminal that supports the NSA architecture and the ENDC function. The following describes related technologies of the embodiments of the present application.
(一)Option3架构(1) Option3 architecture
Option3架构属于NSA，参照图1，LTE演进型基站(evolved NodeB，eNB)通过S1-C(控制面接口)和S1-U(用户面接口)接入演进分组核心网(EPC，Evolved Packet Core)，而下一代基站(next-generation Node B，gNB)与EPC之间仅有S1-U接口。UE通过LTE网络接入EPC。The Option3 architecture belongs to the NSA. Referring to FIG. 1, the LTE evolved NodeB (evolved NodeB, eNB) accesses the evolved packet core network (EPC, Evolved Packet Core) through S1-C (control plane interface) and S1-U (user plane interface) , And the next-generation base station (next-generation Node B, gNB) and EPC only have S1-U interface. The UE accesses the EPC through the LTE network.
(二)ENDC架构(2) ENDC structure
参照图2，在ENDC架构下，LTE eNB作为主节点(Master Node，MN)，gNB作为辅节点(Secondary Node，SN)，MN与EPC之间是S1接口(含S1-C接口和S1-U接口)，SN与EPC之间仅有S1-U接口，MN与SN之间通过X2接口(含X2-C和X2-U)进行ENDC的流程协作。Referring to FIG. 2, under the ENDC architecture, LTE serves as the master node (Master) (MN), gNB serves as the secondary node (SN), and the MN and EPC are the S1 interface (including the S1-C interface and S1-U Interface), there is only S1-U interface between SN and EPC, and ENDC process collaboration is carried out between MN and SN through X2 interface (including X2-C and X2-U).
(三)ENDC架构下的承载(3) Bearing under the ENDC architecture
参照图3，ENDC架构下的承载类型有：主小区组承载(主小区组(Master Cell Group，MCG)Bearer)、辅小区组承载(辅小区组(Secondary Cell Group，SCG)Bearer)、分流承载(Split Bearer)。其中，MCG Bearer是指仅使用LTE无线链路控制(Radio Link Control，RLC)(也即图3中的E-UTRA RLC)的承载，但是MCG Bearer的PDCP可以使用LTE PDCP(也即图3中的E-UTRA PDCP)或NR PDCP(部署在LTE或NR上)；SCG Bearer是指仅使用NR RLC的承载，且使用NR PDCP(部署在LTE或NR上)；Split Bearer是指同时使用LTE RLC和NR RLC的承载，使用NR PDCP。进一步，Split Bearer又分为MCG Split Bearer和SCG Split Bearer，其中，MCG Split Bearer是指承载所使用的NR PDCP是MN管理，SCG Split Bearer是指承载所使用的NR PDCP是SN管理。需要说明的是，RLC是指RLC实体，RLC实体用于实现RLC层的协议功能，PDCP是指PDCP实体，PDCP实体用于实现PDCP层的协议功能。Referring to FIG. 3, the types of bearers under the ENDC architecture are: primary cell group bearer (Master Cell Group (MCG) Bearer), secondary cell group bearer (Secondary Cell Group (SCG) Bearer), offload bearer (Split Bearer). Among them, MCG Bearer refers to using only LTE Radio Link Control (Radio Link Control, RLC) (that is, E-UTRA RLC in Figure 3) bearer, but MCG Bearer PDCP can use LTE PDCP (that is, Figure 3 E-UTRA PDCP) or NR PDCP (deployed on LTE or NR); SCG Bearer refers to the bearer using only NR RLC and uses NR PDCP (deployed on LTE or NR); Split Bearer refers to the simultaneous use of LTE RLC And NR RLC bearer, use NR PDCP. Further, Split Bearer is divided into MCG Split Bearer and SCG Split Bearer. Among them, MCG Split Bearer refers to the NR used by the bearer. PDCP is managed by MN, and SCG Split Split Bearer refers to the NR used by the bearer. PDCP is managed by SN. It should be noted that RLC refers to RLC entities, RLC entities are used to implement RLC layer protocol functions, and PDCP refers to PDCP entities, and PDCP entities are used to implement PDCP layer protocol functions.
(四)ENDC架构下多类型承载的要求(4) Requirements for multiple types of bearers under the ENDC architecture
1、对于MCG Split承载、SCG承载以及SCG Split承载必须使用NR PDCP。1. For MCG Split bearer, SCG bearer and SCG Split bearer, NR PDCP must be used.
2、对于MCG承载，可以使用LTE PDCP或NR PDCP。2. For MCG bearer, LTE PDCP or NR PDCP can be used.
3、对于MCG承载和MCG Split承载，NR PDCP配置必须由MN产生，而对于SCG承载和SCG Split承载，NR PDCP配置必须由SN产生。3. For MCG bearer and MCG Split bearer, NR PDCP configuration must be generated by MN, and for SCG bearer and SCG Split bearer, NR PDCP configuration must be generated by SN.
基于上述的协议架构，在做双连接时，需要在LTE和NR以及EPC之间做大量的信令和数据协同，显著增加处理开销，具体如下：Based on the above protocol architecture, when doing dual connectivity, a large amount of signaling and data coordination between LTE and NR and EPC is required, which significantly increases the processing overhead, as follows:
1、PDCP锚点迁移以及PDCP数据反传1. Migration of PDCP anchors and backhaul of PDCP data
当用户在进入/退出5G小区覆盖时，需要在4G和5G之间频繁迁移PDCP锚点。When users enter / exit 5G cell coverage, they need to frequently migrate PDCP anchors between 4G and 5G.
当用户在连续的5G覆盖之间移动时，需要在5G和5G之间频繁迁移PDCP锚点。When users move between consecutive 5G coverage, they need to frequently migrate PDCP anchors between 5G and 5G.
