Dual Connectivity: Defined in TS 36.300 2. E-RAB: An E-RAB uniquely identifies the concatenation of an S

When an E-RAB exists, there is a one-to-one mapping between this E-RAB and an EPS bearer of the Non Access Stratum (NAS) as defined in TS 23.401 3. S1: logical interface between an eNB and an EPC, providing an interconnection point between the E-UTRA

40、N and the EPC. It is also considered as a reference point. X2: logical interface between two eNBs. Whilst logically representing a point-to-point link between eNBs, the physical realization need not be a point-to-point link. 3.2 Abbreviations For the purposes of the present document, the terms and d

48、ion of signalling and data transport networks. - E-UTRAN and EPC functions are fully separated from transport functions. Addressing scheme used in E-UTRAN and EPC shall not be tied to the addressing schemes of transport functions. The fact that some E-UTRAN or EPC functions reside in the same equipm

49、ent as some transport functions does not make the transport functions part of the E-UTRAN or the EPC. - Mobility for RRC connection is fully controlled by the E-UTRAN. - When defining the E-UTRAN interfaces the following principles were followed: uni25CF The functional division across the interfaces shall have as few options as possible; uni25CF Interfaces should be based on a logical model of the entity controlled through this interface; ETSI ETSI TS 136 401 V14.0.0 (2017-04)93GPP TS 36.401 version 14.0.0 Release 14
