The test specification 3GPP TS 34.171 3 defines test tolerances.

41、 These test tolerances are individually calculated for each test. The test tolerances are then added to the limits in the present document to create test limits. The measurement results are compared against the test limits as defined by the shared risk principle. Shared Risk is defined in ETR 273-1-

42、2 7, subclause 6.5. 4 General 4.1 Introduction The present document defines the minimum performance requirements for both UE based and UE assisted FDD A-GPS terminals. 4.2 Measurement parameters 4.2.1 UE based A-GPS measurement parameters In case of UE-based A-GPS, the measurement parameters are con

43、tained in the RRC UE POSITIONING POSITION ESTIMATE INFO IE. The measurement parameter in case of UE-based A-GPS is the horizontal position estimate reported by the UE and expressed in latitude/longitude. 4.2.2 UE assisted A-GPS measurement parameters In case of UE-assisted A-GPS, the measurement par

44、ameters are contained in the RRC UE POSITIONING GPS MEASURED RESULTS IE. The measurement parameters in case of UE-assisted A-GPS are the UE GPS Code Phase measurements, as specified in 3GPP TS 25.302 5 and 3GPP TS 25.215 6. The UE GPS Code Phase measurements are converted into a horizontal position

45、estimate using the procedure detailed in Annex F. 4.3 Response time Max Response Time is defined as the time starting from the moment that the UE has received the final RRC measurement control message containing reporting criteria different from “No Reporting“ sent before the UE sends the measuremen

46、t report containing the position estimate or the GPS measured result, and ending when the UE starts sending the measurement report containing the position estimate or the GPS measured result on the Uu interface. The response times specified for all test cases are Time-to-First-Fix (TTFF) unless othe

47、rwise stated, i.e. the UE shall not re-use any information on GPS time, location or other aiding data that was previously acquired or calculated and stored internally in the UE. A dedicated test message RESET UE POSITIONING STORED INFORMATION has been defined in TS 34.109 11 clause 5.4 for the purpo

48、se of deleting this information and is detailed in subclause B.1.10. 4.4 Time assistance Time assistance is the provision of GPS time to the UE from the network via RRC messages. Currently two different GPS time assistance methods can be provided by the network. a) Coarse time assistance is always p

49、rovided by the network and provides current GPS time to the UE. The time provided is within 2 seconds of GPS system time. This allows the GPS time to be known within one GPS navigation data sub-frame. It is signalled to the UE by means of the GPS Week and GPS TOW msec fields in the Reference Time assistance data IE. b) Fine time assistance is optionally provided by the network and adds the provision to the UE of the relationship between the GPS system time and the current UTRAN time. The accuracy of this relationship is 10 s of
