39、gnalling information between the eNB and EPC; - from a logical standpoint, the S1 is a point-to-point interface between an eNB within the E-UTRAN and an MME in the EPC. A point-to-point logical interface should be feasible even in the absence of a physical direct connection between the eNB and MME.

40、4.3 S1 interface specification objectives The S1 interface specification shall facilitate the following: - inter-connection of eNBs with MMEs supplied by different manufacturers; - separation of S1 interface Radio Network functionality and Transport Network functionality to facilitate introduction o

41、f future technology. ETSI ETSI TS 136 410 V15.0.0 (2018-07)93GPP TS 36.410 version 15.0.0 Release 154.4 S1 interface capabilities The S1 interface supports: - procedures to establish, maintain and release E-UTRAN Radio Access Bearers; - procedures to perform intra-LTE handover and inter-RAT handover

42、; - the separation of each UE on the protocol level for user specific signalling management; - the transfer of NAS signalling messages between UE and EPC; - location services by transferring requests from the EPC to E-UTRAN, and location information from E-UTRAN to EPC; - mechanisms for resource res

43、ervation for packet data streams. 4.5 S1 interface characteristics 4.5.1 Use of the Stream Control Transmission Protocol (SCTP) The SCTP protocol (IETF RFC 4960 7) is used to support the exchange of S1 Application Protocol (S1AP) signalling messages between an eNB and an MME. 5 Functions of the S1 i

44、nterface protocols and functional split 5.1 General The following clauses describe the functions supported over S1-MME and S1-U to fulfil the S1 interface capabilities. 5.2 S1 UE context management function In order to support UEs in the LTE_ACTIVE state, UE contexts need to be managed, i.e. establi

45、shed and released in the eNB and in the EPC to support user individual signalling on S1. This includes security context management. The S1 UE context management function supports the establishment of the necessary overall initial UE context including E-RAB context, security context, roaming and acce

46、ss restrictions, UE S1 signalling connection ID(s), etc. in the eNB to enable fast idle-to-active transition. The establishment of the overall initial UE context is initiated by the MME. The S1 UE context management function also supports the release of the context previously established in the eNB

47、to enable the active-to-idle transition. The release of the context is triggered by the MME either directly or following a request received from the eNB. 5.3 E-RAB management functions The E-RAB service management function is responsible for establishing, modifying and releasing E-UTRAN resources fo

48、r user data transport once a UE context is available in the eNB. The establishment and modification of E-UTRAN resources is triggered by the MME and requires respective QoS information to be provided to the eNB. For Dual Connectivity when SCG bearer option is applied, the modification of the E-RAB i

49、s triggered by the MeNB towards the MME for the modification of the transport information. The release of E-UTRAN resources is triggered by the MME either directly or following a request received from the eNB (optional).
