31、ent defines one generic RRLP message that is used to transfer Location Services (LCS) related information between the Mobile Station (MS) and the Serving Mobile Location Centre (SMLC). Usage of the RRLP protocol on a general level is described in 3GPP TS 03.71 that includes Stage 2 description of LC
32、S. One message includes one of the following components: ETSI ETSI TS 101 527 V8.18.0 (2007-06) 7 3GPP TS 04.31 version 8.18.0 Release 1999 - Measure Position Request; - Measure Position Response; - Assistance Data; - Assistance Data Acknowledgement; - Protocol Error. Next subchapters describe the u
33、sage of these components. Delivery of components may be supported in the RRLP level using pseudo-segmentation by sending several shorter messages instead of one long message. This may be used to avoid lower level segmentation of messages and/or to improve the reliability of assistance data delivery
34、to the MS in the event that delivery is interrupted by an RR management event like handover. Any assistance data that is successfully delivered to an MS and acknowledged prior to the interruption of the positioning procedure by an event like handover, or by any other event that causes an MS to termi
35、nate the positioning procedure or delivery of assistance data (see subclause 7.11.5 of 3GPP TS 03.71), shall be retained by the MS and need not be resent by the SMLC when positioning or delivery of assistance data is again reattempted. If an SMLC uses pseudo-segmentation, the maximum RRLP PDU size s
36、ent by the SMLC shall be 242 octets. If pseudo-segmentation is not used, the lower layers take care of segmentation if the RRLP message is larger than the maximum message size at the lower layers. 2.2 Position Measurement Procedure This procedure is the same that is described on a more general level
37、 in 3GPP TS 03.71 in the chapter “E-OTD and GPS Positioning Procedures“ in subchapters “Positioning for BSS based SMLC“ and “Positioning for NSS based SMLC“. The purpose of this procedure is to enable the SMLC to request for position measurement data or location estimate from the MS, and the MS to r
38、espond to the request with measurements or location estimate. MSSMLC2. RRLP(Measure Position Request)3. RRLP(Protocol Error)4. RRLP(Measure Position Response)1. Assistance Data Delivery ProcedureFigure 2.1: Position Measurement procedure 1. The Measure Position Request component may be preceded by a
39、n Assistance Data Delivery Procedure (see section 2.3) to deliver some or all of the entire set of assistance data that is needed by the subsequent positioning procedure (steps 2-4). 2. The SMLC sends the Measure Position Request component in a RRLP message to the MS. The component includes QoS, oth
40、er instructions, and possible assistance data to the MS. The RRLP message contains a reference number of the request. 3. The MS sends a RRLP message containing the Protocol Error component to the SMLC, if there is a problem that prevents the MS to receive a complete and understandable Measure Positi
41、on Request component. The RRLP message contains the reference number included in the Measure Position Request received incomplete. The Protocol Error component includes a more specific reason.

42、18.0 Release 1999 component, it may try to resend the Measure Position Request (go back to the step 2), abort location, or start a new position measurement procedure (e.g. with updated assistance data). 4. The MS tries to perform the requested location measurements, and possibly calculates it own po
43、sition. When the MS has location measurements, location estimate, or an error indication (measurements/location estimation not possible), it sends the results in the Measure Position Response component to the SMLC. The RRLP message contains the reference number of the request originally received in
44、the step 2. If there is a problem that prevents the SMLC to receive a complete and understandable Measure Position Response component, the SMLC may decide to abort location, or start a new position measurement procedure instead. 2.3 Assistance Data Delivery Procedure This procedure is the same that
45、is described on a more general level in 3GPP TS 03.71 in the chapter “E-OTD and GPS Positioning Procedures“ in subchapters “Assistance Data Delivery from BSS based SMLC“ and “Assistance Data Delivery from NSS based SMLC“. The purpose of this procedure is to enable the SMLC to send assistance data to
46、 the MS related to position measurement and/or location calculation. Notice that RRLP protocol is not used by the MS to request assistance data, only to deliver it to the MS. The entire set of assistance data (i.e. the total amount of assistance data that the SMLC has decided to send in the current
47、procedure) may be delivered in one or several Assistance Data components. In this case steps 1 and 3 below may be repeated several times by the SMLC. If several components are sent, the SMLC shall await the acknowledgement of each component before the next Assistance Data component is sent. If Assis
48、tance Data Delivery is used as part of the Position Measurement Procedure, as described in clause 2.2, then some assistance data may be delivered in the final RRLP Measure Position Request.

49、Delivery procedure 1. The SMLC sends the Assistance Data component to the MS. The component includes assistance data for location measurement and/or location calculation. The RRLP message contains a reference number of the delivery. The More Assistance Data To Be Sent Element in the Assistance Data component is used by the SMLC to indicate to the MS if more Assistance Data components will be sent in the current Assistance Data Delivery procedure. 2. The MS sends a RRLP message containing the Protocol Error component to the SMLC, if there is a problem
