ETSI ETSI TS 101 726 V8.6.0 (2007-10) 6 2 Messages functional definitions and contents 2.1 General This subclause defines the structure of the messages of the SMLC-BSS layer 3 protocol defined in 3GPP TS 03.71. Each definition includes: a) a brief descriptio

25、n of the message; 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

26、the message; 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 04.07; 4) the format of the IE (T, V, TV, LV, TL

27、V) as defined in 3GPP TS 04.07; 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

28、 bit 8 of the first (lowest numbered octet) and the low order bit is bit 1 of the last (highest numbered octet). c) subclauses specifying conditions for IEs with presence requirement C or O in the relevant message. Together with other conditions specified in 3GPP TS 03.71 this defines when the IE sh

29、all 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 (see 3GPP TS 03.71). 2.2 Messages The following Location Services related messages are exchanged between the SMLC and the BSS, with

30、 the VMSC acting as a relay. 1. TA Request 2. TA Response 3. TOA Request 4. TOA Response 5. Reject 6. Reset 7. Abort 8. TA Layer3 9. MS Position Command 10.

31、 is encapsulated in the BSSMAP-LE Connection Oriented Information message as specified in 3GPP TS 08.08. On the Ls interface the messages are contained in the Location Information IE which is encapsulated in the BSSMAPLE Connection Oriented Information message as specified in 3GPP TS 09.31. 2.2.1 TA

It is sent when the Response message contents for a positioning request are invalidated (e.g. due to handover) before the positioning procedure was completed. The message may also be sent

42、 instead of a Reject when a TOA Request cannot be performed due to an error in the serving cell identity.
