SAMPS supports various location-based services. SAMPS addresses subscri
23、ber-positioning requirements in TIA/EIA- 136-based networks by utilizing the existing Global Positioning System (GPS) infrastructure. SAMPS utilizes the data capabilities of TIA/EIA-136 networks to enhance the performance of GPS-equipped Mobile Stations (MSs) by providing “GPS assistance”. 1 .I Pro
24、toco I H e rarc h y The protocol hierarchy for SAMPS is defied in the following figure. The SAMPS capable MS communicates with the SAMPS Teleservice Server (SAMPS TS) by using the SAMPS Teleservice. Notice that there is both a point-to-point component and a broadcast component to the SAMPS Teleservi

It provides segmentation and re-assembly services, as well as compression and encryption and is conditionally us
26、ed when needed by SAMPS. Note *: beyond the scope of this standard. There are two types of SAMPS TSs. The Serving SAMPS TS provides the SAMPS capable MS with GPS Assistance. The Home SAMPS TS contains subscription and authorization related information. The communication between the Serving SAMPS TS
27、and the Home SAMPS TS is beyond the scope of this standard. For information about the network reference model used for SAMPS (when SAMPS is used for emergency calls), see TIA/EIA/IS-J-STD-036 5. 1 TINEIA-I 36-740 I 1.2 SAMPS TS Address Handling The MS shall determine the correct Multilingual Teleser
28、vice Server Address to use in mobile originated teleservice messages by the following rules. 2 3 For a mobile terminated procedure, the MS shall use the SAMPS TS address indicated in the Multilingual Teleservice Server Address of the initially received R-DATA message of the mobile terminated procedu
29、re. This Multilingual Teleservice Server Address also applies to all deferred responses to the procedure. This Multilingual Teleservice Server Address shall be used by mobile originated positioning assistance request procedures started in support of the mobile terminated procedure (including deferre
30、d procedures). For a mobile originated procedure, if the MS desires to send a message to the Serving SAMPS TS, and it has not been provided with a Multilingual Teleservice Server Address for the Serving SAMPS TS, then it shall use the Designated SAMPS TS Address. 10 II 12 The MS shall use the stored
31、 Home SAMPS TS Address to contact the Home SAMPS TS in mobile originated procedures. Any SAMPS Multilingual Teleservice Server Address that is downloaded via OATS (see TIMEIA-136-720) or stored in the R-UIM (see TIA/EIA-136-033) shall be considered the Home SAMPS TS Address. 13 14 15 16 The Designat
32、ed SAMPS TS Address is a Multilingual Teleservice Server Address that provides a generic address for the Serving SAMPS TS. It is sent in the R-DATA message and it is coded with the following values: 17 18 19 + The “Type of Number” is set to national number 20 + The “Numbering Plan Identification” is
33、 set to unknown 21 + The “Address Encoding Identifier” is set to TBCD 22 + The “Address” is set to 555 726 7787 23 1.3 Mobile Station SAMPS Capabilities 24 This standard defies several kinds of “GPS assistance” that the TIMEIA-136 network can provide in order to enhance the performance of the GPS-eq
34、uipped MS. 25 26 There are two models of operation. One where the Position Computation Function (PCF) is located in the MS and one where it is located in the Network (NW): 27 28 1. 2. MS-Based GPS (PCF in MS) MS-Assisted GPS (PCF in NW) 29 30 1.3.1 MS-Based GPS (PCF in MS) 31 The MS-based model util
35、izes a traditional GPS receiver in the MS. This model may utilize network assistance. In this case, the SAMPS TS sends one or more assistance 32 33 2 TINEIA-I 36-740 messages, which may help the mobile reduce GPS acquisition time, increase sensitivity, compute satellite position, or improve position
36、 determination accuracy. The MS position is computed in the mobile. The mobile determines what assistance information, if any, to use. If assistance information is not used, the mobile is operating in a stand alone mode. 5 1.3.2 MS-Assisted GPS (PCF in NW) The MS-assisted model utilizes a traditiona
37、l GPS receiver in the MS where the Position Calculation function has been moved to the SAMPS TS. The SAMPS TS sends one or more assistance messages to the MS. This assistance may help the embedded GPS sensor reduce the GPS acquisition time or increase sensitivity. The MS returns the pseudorange data
38、 measured by the GPS sensor to the Serving SAMPS TS. The position of the MS is computed in the SAMPS TS. 12 1.3.3 Optional Mobile Station SAMPS Capabilities 13 14 15 16 17 18 19 20 21 22 The following SAMPS capabilities are optional for MSs that support SAMPS: The capability to determine and send Po
39、sition Information as a stand-alone GPS receiver (MS-Based stand-alone) The capability to determine and send Position Information (MS-Based with network assistance) The capability to determine and send the GPS Measurement Data (MS-Assisted) The capabilities supported by the MS are reported to the ne
40、twork in the Capability Report message, the Origination message (see TIA/EIA-136-123), and the Capability Update Response message (see TIA/EIA-136-133).

41、 24 25 26 27 28 29 30 31 32 33 34 35 36 Basic Operations The following SAMPS message procedures apply to SAMPS message transactions on the DTC and on the DCCH. Positioning Assistance Data Broadcast 2.2 The Positioning Assistance Data message uses the Broadcast Air-Interface Transport Service (BATS),
42、 see TIA/EIA-136-630. The MS may read the Positioning Assistance Data message at any point that it determines appropriate. The MS may also obtain some information from the SAMPS Parameters message on the E-BCCH. Mobile Terminated Positioning Request Procedure The Mobile Terminated Positioning Reques
43、t Procedure is invoked by the MS upon receipt of the Measure Position Request message from the Serving SAMPS TS. This message is used by the Serving SAMPS TS to ask the MS for position information or GPS measurements. It may also be used to ask the MS for reference time for a specific DCCH. The MS m
44、ay use the Preferred Type of Positioning Information Element (IE) to determine what type of response to return in the Measure Position Response message. The MS may use the Positioning Client Identity IE or the absence of that IE to determine whether to respond to the Measure Position Request with a
45、success, request declined indication. If any optional GPS assistance information is included, the MS may read and use it. If the MS accepts the Measure Position Request, and the QoS Parameters IE is included, then the MS shall read it and determine to what level it will comply with the requested QoS
46、. If the Kiwi field of the QoS Parameters IE indicates Do not return a position or measurements if the QoS is not fulfilled and the MS is not fulfilling the QoS parameters, then the MS shall not include the Position Information IE or the GPS Measurement Data IE in the Measure Position Response messa
47、ge and the SAMPS Result IE shall indicate Success, request declined. Optionally, if the MS determines that it needs more GPS Assistance Data, the MS may invoke the Mobile Originated Positioning Assistance Request Procedure before responding to the Measure Position Request message. The MS shall retur
48、n a Measure Position Response message with a result indication. If the Preferred Type of Positioning IE in the Measure Position Request indicated MS- Based GPS and the MS desires to and is able to return the information, the MS shall include either the Position Information IE or the GPS Measurement
49、Data IE in the Measure Position Response message. 4 TINEIA-I 36-740 9 10 II 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 If the Preferred Type of Positioning IE in the Measure Position Request indicated MS- Assisted GPS and the MS desires to and is able to return the information, the MS shall include either the GPS Measurement Data IE or the Position Information IE in the Measure Position Response message. The MS shall always accept and respond to a Measure Position Request which indicates a Public Safety A
