29、The present document defines the coding of information in an extension of the Base Station System Application Part (BSSAP) that is needed to support location services on interfaces based on use of BSSAP. The contents of the present document are subject to continuing work within the TSG and may chang
30、e following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presen
31、ted to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in t
32、he document. ETSI ETSI TS 101 530 V8.7.1 (2004-05) 7 3GPP TS 09.31 version 8.7.1 Release 1999 1 Scope The present document specifies procedures and information coding that are needed to define and support the BSSAP LCS Extension (BSSAP-LE). The BSSAP-LE message set is applicable to the following GSM
33、 interfaces defined in 3GPP TS 03.71: Lb interface (BSC-SMLC). Ls interface (MSC-SMLC). Lp interface (SMLC-SMLC). The present document defines message formats and encoding for BSSAP-LE and the particular subsets of it that are applicable to each of the above interfaces. The present document also def
34、ines the support for BSSAP-LE message transfer on each of these interfaces using CCITT and ANSI versions of SS7 MTP and SCCP. Additional requirements for the above interfaces that are applicable to BSSAP-LE are also defined e.g. usage of BSSAP (as defined in 3GPP TS 04.08 and 08.08) on the Lb interf
35、ace. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subse
36、quent revisions do not apply. For a non-specific reference, the latest version applies.

The following subse
45、ts of BSSAP-LE are defined: DTAP-LE, BSSMAP-LE. 4.1 DTAP-LE Messages DTAP-LE messages are transfered between an SMLC and a Type A LMU and comprise the following individual messages: REGISTER FACILITY RELEASE COMPLETE The content, encoding and certain procedures asssociated with DTAP-LE messages are

48、owledge The content and encoding of BSSMAP-LE messages are defined in this specification. 5 Procedures applicable to use of BSSAP-LE 5.1 Location Request The Location Request procedure is applicable to the Lb and Ls interfaces. Its purpose is to obtain a location estimate for a target MS that is alr
49、eady in dedicated mode. It is also used to provide an MS with LCS assistance data or with a deciphering key for LCS broadcast assistance data. The initiator of a location request may be either the serving BSC or the visited MSC for the MS. The procedure makes use of SCCP connection oriented signaling on the Lb and Ls interfaces. 5.1.1 Successful Operation The initiator of the location request (VMSC or serving BSC) sends a BSSMAP-LE Perform Location Request to the SMLC associated with the current serving cell for
