30、ent Entity O - the SLm interface shall support the exchange of signalling information between the LMU and E-SMLC; - from a logical standpoint, the SLm is a point-to-point interface between an LMU within the E-UTRAN and an E-SMLC in the EPC. A point-to-point logical interface should be feasible even

31、in the absence of a physical direct connection between the LMU and E-SMLC. 4.3 SLm interface specification objectives The SLm interface specification shall facilitate the following: - inter-connection of E-SMLCs with LMUs supplied by different manufacturers; - separation of SLm interface Radio Netwo

32、rk functionality and Transport Network functionality to facilitate introduction of future technology. 4.4 SLm interface capabilities The SLm interface supports: - procedures to establish, maintain and release connections between the E-SMLC and LMUs; - the separation of each LMU on the protocol level

33、 for specific signalling management; - location services by transferring location requests from the E-SMLC to LMUs, and UL RTOA measurements from LMUs to E-SMLC; ETSI ETSI TS 136 456 V14.0.0 (2017-04)83GPP TS 36.456 version 14.0.0 Release 144.5 SLm interface characteristics 4.5.1 Use of SCTP The SCT

34、P (IETF RFC 4960 7) is used to support the exchange of SLm Application Protocol (SLmAP) signalling messages between an LMU and an E-SMLC. 5 Functions of the SLm interface protocol 5.1 General The following sections describe the functions to fulfil the SLm interface capabilities. 5.2 SLm link managem

35、ent function The SLm signalling link management function provides a reliable transfer of the signalling between LMU and E-SMLC. 5.3 SLm interface management function The error indication function is used by the LMU (respectively the E-SMLC) to indicate to the E-SMLC (respectively the LMU) that a log

36、ical error has occurred. The reset procedure is used to initialize the peer entity after node setup and after a failure event has occurred. This procedure can be initiated by the E-SMLC or the LMU. The information about the LMU capabilities after a reset is preserved in the E-SMLC. The SLm Setup pro

37、cedure allows the exchange of application level data, e.g. capability, needed for the LMU and E-SMLC to interoperate correctly on the SLm interface. This procedure is originated by the LMU only and initiates the setup of the SLmAP contexts to the E-SMLC. 5.4 SLm location function The location functi

38、on is used by the E-SMLC to request the LMU to perform UL RTOA measurements. The LMU reports UL RTOA measurements back to the requesting E-SMLC. 6 SLm interface protocol structure Editors Note: Protocol Structure following the structure defined in TS 36.305 2. 6.1 General The network signalling over

39、 SLm consists of the SLm Application Protocol (SLmAP). The SLmAP consists of mechanisms to handle all procedures between the E-SMLC in the EPC and LMUs in the E-UTRAN. Over the SLm interface the SLmAP protocol is, e.g., used to: - Request LMUs to perform UL RTOA measurements of target UE SRS transmi

40、ssions. - Transfer of completed UL RTOA measurements from the LMU to the E-SMLC.
