32、TS 148 071 V15.0.0 (2018-07)73GPP TS 48.071 version 15.0.0 Release 154 Messages functional definitions and contents 4.1 General This sub-clause defines the structure of the messages of the SMLC-BSS layer 3 protocol defined in 3GPP TS 43.059. Each definition includes: a) a brief description of the me
33、ssage; b) a table listing the information elements in the order of their appearance in the message. For each IE the table indicates: 1) the name of the IE (which gives an idea of the semantics of the element), which is used in this and other specifications as a reference to the IE within the message
34、; 2) the name of the type of the IE (which indicates the coding of the value part of the IE), and a reference to a description of the value part of the IE; 3) the presence requirement indication (M, C or O) for the IE, as defined in 3GPP TS 24.007; 4) the format of the IE (T, V, TV, LV, TLV) as defi
35、ned in 3GPP TS 24.007; 5) the length of the IE (or permissible range of lengths), in octets, in the message. The value of the length gives the number of octets in the IE following the length and element identifier. Where the length is encoded using more than one octet, the high order bit is bit 8 of
36、 the first (lowest numbered octet) and the low order bit is bit 1 of the last (highest numbered octet). When a length has a range of M to N octets, the notation “M-N“ is used. The symbol “n“ represents the maximum of a range when indefinite. c) sub-clauses specifying conditions for IEs with presence
37、 requirement C or O in the relevant message. Together with other conditions specified in 3GPP TS 43.059 this defines when the IE shall be included or not, what non-presence of such IEs means, and (for IEs with presence requirement C) the static conditions for presence and/or non-presence of the IEs
38、(see 3GPP TS 43.059). 4.2 Messages The following Location Services related messages are exchanged between the SMLC and the BSS: - TA Request; - TA Response; - Reject; - Reset; - Abort; - TA Layer3; - MS Position Command; - MS Position Response; - U-TDOA Request; - U-TDOA Response. On the Lb interfac
39、e the messages are contained in the BSSLAP APDU IE which is encapsulated in the following messages as specified in 3GPP TS 49.031: - BSSMAP-LE CONNECTION ORIENTED INFORMATION message (for all messages except the TA LAYER 3 message); ETSI ETSI TS 148 071 V15.0.0 (2018-07)83GPP TS 48.071 version 15.0.

It is sent when the Response messag
