37、ing Protocol IP Internet Protocol LTE Long Term Evolution MeNB Master eNB MME Mobility Management Entity O - the S1 interface shall support the exchange of signalling information between the eNB and EPC; - from a logical standpoint, the S1 is a point-to-point interface between an eNB within the E-UT
38、RAN 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. ETSI ETSI TS 136 410 V14.0.0 (2017-04)93GPP TS 36.410 version 14.0.0 Release 144.3 S1 interface specification objectives The S1 interface spec
39、ification 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 of future technology. 4.4 S1 interface capabilities The S1 inter
40、face supports: - procedures to establish, maintain and release E-UTRAN Radio Access Bearers; - procedures to perform intra-LTE handover and inter-RAT handover; - the separation of each UE on the protocol level for user specific signalling management; - the transfer of NAS signalling messages between
41、 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 reservation for packet data streams. 4.5 S1 interface characteristics 4.5.1 Use of the Stream Control Transmission Protocol (SCTP) The SCTP proto
42、col (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 interface protocols and functional split 5.1 General The following clauses describe the functions supported over S1-MME and S1-U to fulfil the
43、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. established and released in the eNB and in the EPC to support user individual signalling on S1. This includes security context management. The S1 UE
44、context management function supports the establishment of the necessary overall initial UE context including E-RAB context, security context, roaming and access restrictions, UE S1 signalling connection ID(s), etc. in the eNB to enable fast idle-to-active transition. The establishment of the overall
45、 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 to enable the active-to-idle transition. The release of the context is triggered by the MME either directly or following a request received fr
46、om the eNB. ETSI ETSI TS 136 410 V14.0.0 (2017-04)103GPP TS 36.410 version 14.0.0 Release 145.3 E-RAB management functions The E-RAB service management function is responsible for establishing, modifying and releasing E-UTRAN resources for user data transport once a UE context is available in the eN
47、B. 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 is triggered by the MeNB towards the MME for the modification o
48、f 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). 5.4 S1 link management function 5.4.1 GTP-U tunnels management function This function is used to establish and release GTP-U (3GPP TS 29.281
49、8) tunnels between the EPC and the E-UTRAN upon an E-RAB service request. This involves assigning a tunnel identifier for each direction. 5.4.2 S1 signalling link management function The S1 signalling link management function provides a reliable transfer of the radio network signalling between E-UTRAN and EPC. 5.5 Mobility functions for UEs in LTE_Active 5.5.1 Intra-LTE handover The Intra-LTE handover function supports mobility for UEs in LTE_ACTIVE and comprises the preparation, execution and completion of handover via the X2 and S1 in
