ETSI ETSI TS 101 293 V8.6.0 (2004-07) 6 3GPP TS 04.14 version 8.6.0 Release 1999 1 Scope The present document specifies for Mobile Stations (MS), for the digital cellular communication
19、s system and Personal Communication Systems (PCS) operating in the 900 MHz and 1800 MHz band (GSM900 and DCS1800), standardized by ETSI SMG, those ME functions which are required for conformance testing purposes only. However, except for the Electrical Man Machine Interface (EMMI) and the Multi-slot
20、 TCH Loops, they are required for every mobile station. For conformance tests, functions are activated via the radio interface, test SIM or dedicated pins. These functions must be capable of being activated when a test SIM is present but must not function with any other (e.g. network) SIM present ex
21、cept where otherwise stated within the present document. In this state, the MS must be able to perform all functions specified in the present document; in addition however, the special conformance testing functions must be operational. The special conformance testing functions of the ME are enabled
22、by use of a dedicated Subscriber Identity Module (test SIM, see 3GPP TS 11.10-1 Annex 4). SIM, in general, is described in 3GPP TS 11.11. The ME recognizes the test SIM by the Administrative Data Field. The present document applies to the public land mobile radio service in the GSM900 and DCS1800 sy
23、stems, using constant envelope modulation and operating on radio frequencies in the 900 and 1800 MHz bands respectively with a channel separation of 200 kHz and carrying 8 full rate channels or 16 half rate channels per carrier according to the TDMA principle. The present document is part of the GSM
24、-series of technical specifications. The present document neither replaces any of the other GSM technical specifications or GSM related TS, nor is it created to provide full understanding of (or parts of) the GSM900 and DCS1800 systems. The present document applies to the unit which includes the har
25、dware to establish a connection across the radio interface. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

30、S can be: - a vehicle mounted station; - a portable station; - a handheld station; - a vehicle mounted/portable station; - a vehicle mounted/handheld station. For a more detailed description of MS-configurations, see 3GPP TS 02.06. 3.2 Applicability The present document is applicable to all MSs. 4 A
31、ctivation and deactivation of special test functions in the MS The functions described in the present document can be activated and deactivated from a SS by sending appropriate layer 3 commands to the MS. The protocol discriminator to be used is defined in 3GPP TS 04.08, subclause 10.2. The layer 3
32、commands are sent on the DCCH. On layer 2, SAPI 0 is used in acknowledged mode. Apart from sending the appropriate deactivation command to the MS the functions can be deactivated by switching off the MS or removing the test SIM. The following test functions can be activated (and deactivated): - TCH
33、Loop; - TCH Burst-by-Burst Loop; - Multi-slot Loop; - Electrical MMI; - Test via DAI. The TCH loops and the test via DAI are test functions which are mutually exclusive. ETSI ETSI TS 101 293 V8.6.0 (2004-07) 8 3GPP TS 04.14 version 8.6.0 Release 1999 5 Internal test loops A number of internal test l
34、oops are required providing access to isolated functions of the MS without introducing new physical interfaces just for the reason of type approval testing. Fig 5-1 shows a functional block diagram of a reference MS containing the different test loops. NOTE: It should be emphasized that these test l
35、oops only describe the functional behaviour of the MS with respect to its external interfaces; physical implementation of the loops is completely left open to the manufacturer. A particular loop is activated in an MS by transmitting the appropriate command message to the MS. Channeldecoder(speech)Ch

37、the case of loops A and B, when a TCH/EFS is used, the MS loops back 244 bits instead of 260 bits, see subclauses 5.1.2.1 and 5.1.3.1.

38、t TCH loops To establish a transparent loop for TCH blocks a TCH must be active between the SS and MS. The TCH may be full or half rate, speech or data of any rate specified in the GSM system. Six types of Single-slot TCH loop back are defined. The first (A) includes the signalling of erased frames
39、and is used to determine Frame Erasure Ratio (FER) and Residual Bit Error Ratio (RBER) for speech TCH and Bit Error Ratio (BER) for any data TCH. The second type (B) is required to determine Class II bit error ratio for the speech TCH. With the third loop (C) the 114 information bits of each TCH bur
40、st (excluding stealing flags) prior to applying benefit of the channel decoder, but after decryption, shall be transmitted in an uplink burst. (Equivalent error rate to TCH/FS Class II). All that is received shall be re-transmitted regardless of the state of the received midamble. The midamble in th
41、e uplink bursts shall be the normal midamble used by the MS. SACCH and idle bursts are not looped back. The fourth loop (D) includes the signalling of erased frames and unreliable frames and is used to determine Unreliable Frame Ratio (UFR) and Residual Bit Error Ratio (RBER) for TCH/HS. The fifth l
42、oop (E) includes the signalling of erased SID frames and is used to determine Erased SID Frame Rate (ESIDR) and Residual Bit Error Ratio (RBER) for TCH/HS. The sixth loop (F) includes the signalling of erased valid SID frames and is used to determine Erased Valid SID Frame Rate (EVSIDR) and Residual
43、 Bit Error Ratio (RBER) for TCH/HS. NOTE: Measurement of TCH/FS chip BER is approximately five times faster using loop C rather than loop B. 5.1.2 TCH loop including signalling of erased frames (A) 5.1.2.1 Procedure The SS orders the MS to close its TCH loop by transmitting a CLOSE_TCH_LOOP_CMD mess
44、age, specifying the TCH to be looped and that erased frames are to be signalled by the MS. The SS then starts timer TT01. If no TCH is active, or any test loop is already closed, the MS shall ignore any CLOSE_TCH_LOOP_CMD message. If a TCH is active, the MS shall close its TCH loop for the TCH speci
45、fied and send back to the SS a CLOSE_TCH_LOOP_ACK message. Upon reception of that message the SS stops timer TT01. After the MS has closed its TCH loop, every good speech frame or any user data frame received by the MS on the specified TCH (downlink) shall be taken from the output of the channel dec
46、oder, input to the channel encoder and transmitted on the same TCH (uplink). In the case where TCH is TCH/FS or TCH/HS, the MS shall loop back the 260 bits after normal channel decoding. In the case where TCH is TCH/EFS, the MS shall loop back the 244 bits after normal and preliminary channel decodi
47、ng. If the channel decoder detects a bad speech frame , then this shall be signalled to the SS by setting the input frame to the channel encoder to zeros, and transmitting on the TCH (uplink). If the MS decodes stealing flags as indicating an FACCH frame, then there is no defined response for the MS
48、 to the channel encoder for transmission on the TCH (uplink). The FACCH channel shall operate as normal.

49、TCH loop by transmitting a CLOSE_TCH_LOOP_CMD message, specifying the TCH to be looped. The SS then starts timer TT01. If no TCH is active or any test loop is already closed, the MS shall ignore any CLOSE_TCH_LOOP_CMD message. If a TCH is active, the MS shall close its TCH loop for the TCH specified and send back to the SS a CLOSE_TCH_LOOP_ACK. Upon reception of that message the SS stops timer TT01. After the MS has closed its TCH loop, any speech frame received by the MS on the specified TCH (downlink) shall be taken from the output of the channel decoder,
