30、xchange 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 in the absence of a physical direct connection betwe

31、en 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 Network functionality and Transport Network functionality

32、 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 for specific signalling management; - location serv

34、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 management function The SLm signalling link management func

35、tion 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 logical error has occurred. The reset procedure is used

36、 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 procedure allows the exchange of application level data

37、, 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 function is used by the E-SMLC to request the LMU to perfo

38、rm 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 SLm consists of the SLm Application Protocol (SLmAP

39、). 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 transmissions. - Transfer of completed UL RTOA measurements

40、 from the LMU to the E-SMLC.
