Foreword
rd
This Technical Specification has been produced by the 3 Generation Partnership Project (3GPP).
The present document defines the contents of LCS assistance data broadcast messages from the Serving Mobile
Location Centre (SMLC) and the Mobile Station (MS).
The contents of the present document are subject to continuing work within the TSG and may change 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 presented 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 the document.

1 Scope
The present document contains the coding of information necessary for support of location service operation on the
mobile radio interface layer 3 between the LMU and SMLC.
Clause 4 defines generic procedures for the control of location services. In clause 5 location service support procedures
are defined. Clause 6 gives the functional definitions and contents of messages for location service operations. Clause 7
gives the general format and coding for messages used for location service and the format and coding of information
elements used for location service operations. Clause 6 gives the detailed message format and information elements
coding between the LMU and SMLC.
Clause 8 gives the specification of the LMU LCS Protocol (LLP) operations. In clause 9 LMU - SMLC messages, data
types and identifiers are given.
This version does not support segmentation of messages.
