27.12 Evaluation of directory characteristics

3GPP51.010-1Mobile Station (MS) conformance specificationPart 1: Conformance specificationTS

27.12.1 Operating speed in authentication procedure

27.12.1.1 Definition

Authentication is performed by a GSM network on the SIM, by sending a random number to the SIM. The SIM then performs a calculation on the random number, and sends the result to the network for verification.

27.12.1.2 Conformance requirement

If bit b2 of the file characteristics is set to 1, then the ME shall provide a clock frequency of at least 13/4 MHz to enable the SIM to run the authentication process in the required time.

3GPP TS 11.11, subclause 5.4.

27.12.1.3 Test purpose

To verify that the authentication procedure is done with a frequency of at least 13/4 MHz if the bit b2 of the file characteristics (byte 1 of the directory characteristics) is set to 1.

27.12.1.4 Method of test

27.12.1.4.1 Initial conditions

System simulator:

1 cell, default parameters.

Mobile Equipment:

Connected to a SIM-simulator with bit b2 of the file characteristics set to 1.

ME is powered on.

27.12.1.4.2 Procedure

An authentication is made in the same way as in test [26.7.2. Authentication]. The MS is paged. After the MS has responded with a PAGING RESPONSE message to the SS, the SS initiates an authentication procedure, sending the MS the value RAND. During authentication, the SIM simulator checks the frequency of the clock supplied by the ME. Following the AUTHENTICATION RESPONSE from the MS, the SS sends CHANNEL RELEASE.

27.12.1.5 Test requirement

The frequency of the clock shall be at least 13/4 MHz during the authentication procedure.

27.12.1a Operating speed in authentication procedure – for GPRS

27.12.1a.1 Definition

Authentication is performed by a GSM network on the SIM, by sending a random number to the SIM. The SIM then performs a calculation on the random number, and sends the result to the network for verification.

27.12.1a.2 Conformance requirement

If bit b2 of the file characteristics is set to 1, then the ME shall provide a clock frequency of at least 13/4 MHz to enable the SIM to run the authentication process in the required time.

3GPP TS 11.11 / 3GPP TS 51.011, subclause 5.4.

27.12.1a.3 Test purpose

To verify that the authentication procedure is done with a frequency of at least 13/4 MHz if the bit b2 of the file characteristics (byte 1 of the directory characteristics) is set to 1.

27.12.1a.4 Method of test

27.12.1a.4.1 Initial conditions

System simulator:

The SS transmits default message contents of Cell A, subclauses 40.1.1 and 40.2.1.1 on the BCCH, with the exception that Network Mode of Operation is set to NMO II.

Mobile Equipment:

Connected to a SIM-simulator with EF contents of GPRS SIM and additional with bit b2 of the file characteristics set to 1.

27.12.1a.4.2 Procedure

a) The MS is powered on.

b) After receipt of a CHANNEL REQUEST from the MS, the SS sends IMMEDIATE ASSIGNMENT to the MS.

c) After receipt of an ATTACH REQUEST from the MS, the SS sends AUTHENTICATION AND CIPHERING REQUEST to the MS, includes RAND set to any allowed value.

d) During authentication procedure, the SIM simulator checks the frequency of the clock supplied by the ME.

e) After receipt of an AUTHENTICATION AND CIPHERING RESPONSE from the MS, the SS sends ATTACH ACCEPT to the MS.

f) The MS is soft powered down.

27.12.1a.5 Test requirement

The frequency of the clock shall be at least 13/4 MHz during the authentication procedure.

27.12.2 Clock stop

27.12.2.1 Definition

The ME may switch off the clock signal to the SIM, but only if the SIM indicates that it supports this feature.

27.12.2.2 Conformance requirement

1. The ME shall not stop the clock, unless the requirements indicated in byte 1 of the file characteristics are met.

3GPP TS 11.11, subclauses 5.6 and 9.2.1.

2. The ME shall wait at least 1 860 clock cycles after having received the last character including the minimum guard time (2 etu) of the response before switching off the clock. The ME shall wait at least 744 clock cycles before it sends the first command after having restarted the clock.

3GPP TS 11.11, subclause 5.6.

27.12.2.3 Test purpose

1. To verify that the clock is only switched off if requirements are met as indicated in the file characteristics (byte 1 of the directory characteristics).

2. To verify that the timing of the clock switching is as specified.

27.12.2.4 Method of test

27.12.2.4 Method of test

Specific PICS statements:

  • 5V only SIM/ME interface (TSPC_AddInfo_5V)

27.12.2.4.1 Initial conditions

The ME is connected to a SIM simulator. CHV 1 is enabled.

27.12.2.4.2 Procedure

a) A SIM simulator is used with bits set as follows:

Bit b1 Bit b3 Bit b4

0 0 0

b) The ME is powered on. When the ME is in mode PIN check, 10 s shall elapse before the PIN is entered.

c) The ME is powered off, and a SIM simulator is used with bits set as follows:

Bit b1 Bit b3 Bit b4

0 1 0

d) The ME is powered on. When the ME is in mode PIN check, 10 s shall elapse before the PIN is entered.

e) The ME is powered off, and a SIM simulator is used with bits set as follows:

Bit b1 Bit b3 Bit b4

0 0 1

f) The ME is powered on. When the ME is in mode PIN check, 10 s shall elapse before the PIN is entered.

g) The ME is powered off, and a SIM simulator is used with bits set as follows:

Bit b1 Bit b3 Bit b4

1 0 0

h) The ME is powered on. When the ME is in mode PIN check, 10 s shall elapse before the PIN is entered.

27.12.2.5 Test requirement

1. During step b), the ME shall not switch off the clock. This applies only to MEs supporting 5V SIM interface (see PICS).

2. During step d), the ME shall not switch off the clock, unless at high level.

3. During step f), the ME shall not switch off the clock, unless at low level.

4. During steps d), f) and h), the ME shall not switch off the clock until at least 1 860 clock cycles after having received the last character of the response including the minimum guard time (2 etu).

5. During steps d), f) and h), the ME shall wait at least 744 clock cycles before it sends the first command after having restarted the clock.
