5、oa _ 3404583 00335q8 2nd Final draft prl-ETS 300 020-2992 Foreword This second final draft Interim European Telecommunication Standard (I-ETS) has been produced by the Special Mobile Group (SMG), a Technical Committee of the European Telecommunications Standards Institute (ETSI). The text of this 2n
6、d draft I-ETS may be utilized, wholly or in part, for the establishment of NET 10, Part 2. The first final drafts dealing with the GSM (phase 1) system were adopted by vote in May 1991 but were not published. This was because amendments, agreed by ETSI TC-SMG at subsequent meetings, were made to som
7、e of the drafts. However, other drafts have not been amended since the first vote. This updated draft, is now considered to be stable enough to be submitted for second vote. The relevant type approval procedures for the mobile station are given in CEPT recommendation T/R 21 -08. This standard origin
8、ally had 1-ETS status at the Public Enquiry phase, but this was changed to an ETS for the first vote. However, due to a decision by the ETSI Technical Assembly, this “interim“ status was restored. This second final draft consists of the following part numbers and titles: a) prl-ETS 300 020-1 Europea

10、ion (Candidate NET 10, Part 2) Reference: GSM 11.40. This part of the I-ETS, the system simulator specification, describes the measurement arrangement required to test mobile stations for conformity to I-ETC 300 020-1, Mobile station conformity specif cations. Reference is made within this draft to
11、the following technical specifications (NOTE 1): GSM 02.06 “Types of Mobile Station (MS).“ GSM 02.07 “Mobile station features.“ The above specifications, together with Annexes B, C, G and H of this ETS, are normative. NOTE 1: ETSI has constituted stable and consistent documents which give technical
12、specifications for the implementation of the European Digital Cellular Telecommunications System. Historically, these documents have been identified as “GSM recommendations“. Some of these recommendations may subsequently become Interim European Telecommunication Standards (I-ETSs) or European Telec
13、ommunication Standards (ETSs), whilst the others will be renamed ETSI-GSM Technical Specifications. These ETSI-GSM Technical Specifications are, for editorial reasons, still referred to as GSM recommendations in some current GSM documents. 2nd Final draft prl-ETS 300 020-2: 1992 3404583 0033599 8 -

FuNmIoNAL REQuIREIIpiIs 2.1 GENERAL The system simulator shall perform the tests of the Mobile Station described in GSM 11.1
32、0. The system simulator has to simulate the network side of the MS-BSS interface as seen by the MS. The system simulator does not include environmental test equipment such as climatic chambers. anechoic shielded chamber. vibration or rotation devices. The System Simulator is required to take account
33、 of losses and effects of test apparatus connected externally for the purpose of testing, adjusting the test results accordingly. 2.2 THE SIMULATED RADIO NGIWORK The SS shall be able to simulate a radio environment consisting of up to 8 cells. Two of these cells shall be simulated with 1 BCCH and 1
34、physical channel each. 6 of the cells shall be simulated by transmitting 6 independent BCCHs. It shall be possible to transnit simultaneously all 8 BCCHs and the downlink of the 2 physical channels. The SS shall be able to receive signals from the MS on the 2 physical channels and 1 RACH. Examples o
35、f signalling procedures leading to the above requirements on the system simulator are in Appendix 1 of this part. Some possible test configurations are given in Appendix 2 of this part. 3401.1583 O033604 8 W CSM 11.40 page 5 V.3.j.O/Feb ;992 2.2.1 Transission capabilities The SS shall simulate two c
36、ells with the following functions in each: - Frequency hoppin , see section 2.3.1.2 - Fading, see 3.4.8, on serving cell and first interferer, see 3.4.7 - Adjustable RF output power - Adjustable delay, see 2.3.1.5 - Adjustable multiframe structure (Tl, T2, T3), see 2.3.1.2 - 1 BCCH channel with powe
37、r ramping - 1 physical channel used as either PCH, AGCH, SECH, TCH (SACCH, FACCH) or as either the wanted signal or the first interferer. The RF requirements for the 2 cells are given in section 3.4. The SS shall in addition transmit the BCCH of 6 independent cells with the following characteristics
38、: - Adjustable RF output power: - Adjustable delay: - Adjustable multiframe structure: - Non correlated frequencies/timing. The RF requirements for the 6 BCCHs are given in section 3.4.4/3.4.7. It is acceptable that these 6 BCCHs tramait continuously without power ramping. For measurements of the MS
39、 at least the following test signals are to be transmitted by the SS, see section 3.4: - The Wanted signal with and without fading; - The First interfering signal with and without fading; - The Second interfering si al: - Signal for substitution o pi“ spurious signal. 2.2.1.1 standard test signals T
40、he following test signals shall be generated by the test equipment. Cx signals represent the wanted signals and the Ix signals represent the The unwanted sign-als. - signal CO - signal c1 - Signal IO - Signal Il - signal I2 Unmodulate continuous carrier: A standard GSM signai with the modulation der
41、ived by applying a data reversals signal to the input of a channel coder. The channel coder will depend on the test and the cyphec moe shall be selectable by the test method. When using this signai in the non hopping mode, the unused seven time slots shall also contain dummy bursts, with power level
42、s variable with respect to the used timeslot, see also 2.3.1.3. Unmoulated continuous carrier: A GMSK modulated carrier following the structure of the CiSM signals, but with all modulating bits (including the midamble period) derived directly from a randoa or pseudo random data stream. A standard GS
43、M signal with valid midamble, different from C1. The data bits (including bits 58 and 59) shall be derived from a random or pseudo random data stream. 4 - 3404583 0031b05 T GSM 11.40 page 6 V.3.5.OIFeb 1592 2.2.2 Reccptim capabilities The SS shall be able to receive simultaneously on at least two ph
44、ysical channels with the following functions in each: - Frequency hoppin - Adjustable multiframe structure (Tl,T2,T3) - Reception on the CCCH- (RACH), SDCCH, TCH (SACCH. FACCH). The receiving function shall be interconnected to the relevant transmission function. The SS shall in addition have the fo
45、llowing RF measurement capabilities, see section 3.3: - Average F power - Time mask power measurements - Selective RF Dower - Phase trajectory-and frequency error - RF delay. The receiver should be capable of performing the tests as specifi d in the receiver performance when operated with a MS which
46、 meets the transmitter requirements of GSM 05.05. Note: Note: For the test of cell selection/reselection (GSM 11.10/11.6), one of GSM 11.10 without the addition of bit errors in excess of 1 in 10 9 due to This requirement is based on a minimum BER measurement of 10-5. the following additional receiv
47、e functions is required: - a wide band receive function. such as for instance a spectrum analyzer (this is the preferredsolution) , or - an additional receive function for the CSM type of channel. 2.3.1 Pbysica interiace The SS shall support the full range of transmit and receive frequencies of a ba
48、se station system. The SS shall support all traffic channels for speech and data and all control channels. The frequency bands, channels and channel numbering are according to the GSM O5 series of recommendations. Note: In the future, the System Simulator may additionally utilize frequencies outside
49、 the GSM band (see also GSM 05.05). Consequently these frequencies may be included in this section later. 2.3.1.1 Activation of CLS typt testing functions It shall be possible to activate special type testing functions in the MS, defined in GSM 11.1O/III.l. 92 / 95 m L 3404583 003LbOb L CSM 11.40 page 7 V.3.5.O/Feb i992 2.3.1.2 Channel parameters and frequency hopping It shall se aossible to assign parameter values in the SS for channel definition and assignment for the two simulated BSS and the BCCHs of the adjacent cells independently.
