27.7a MS deleting forbidden PLMNs – for GPRS

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

27.7a.1 Definition

In manual PLMN selection mode the MS allows registration attempts to all available PLMNs, including forbidden PLMNs (as indicated by the forbidden PLMN list on the SIM). As a result of a successful GPRS attach procedure onto a PLMN which is in the forbidden PLMN list, the forbidden PLMN list is automatically updated by the MS.

27.7a.2 Conformance requirement

1. The UE shall select and attempt registration on other PLMNs, if available and allowable, if the location area is not in the list of "forbidden LAs for roaming" and the tracking area is not in the list of "forbidden TAs for roaming" (see 3GPP TS 23.122 [3]), in the following order:

In the case of a UE operating in UE operation mode A or B, an allowable PLMN is one which is not in the "Forbidden PLMN" data field in the SIM/USIM . This data field may be extended in the ME memory.(see subclause 3.2.2.4). In the case of a UE operating in UE operation mode C, an allowable PLMN is one which is not in the "Forbidden PLMN" data field in the SIM/USIM or in the list of "forbidden PLMNs for GPRS service" in the ME.

3GPP TS 02.11 / 3GPP TS 22.011 subclause 3.2.2.2 A)

2. The MS shall indicate whether there are any PLMNs, including "Forbidden PLMNs", which are available. If there are none, this shall also be indicated.

[…]

The user may select his desired PLMN and the MS shall attempt registration on this PLMN. (This may take place at any time during the presentation of PLMNs.)

3GPP TS 02.11 / 3GPP TS 22.011, subclause 3.2.2.2 B)

3. If a successful registration (whilst in manual mode) is achieved on a PLMN in the "Forbidden PLMN" list, the PLMN shall be deleted from the list.

3GPP TS 02.11 / 3GPP TS 22.011, subclause 3.2.2.4 1

27.7a.3 Test purpose

1) To verify that in automatic PLMN selection mode the MS does not attempt to access PLMNs stored in EFFPLMN on the SIM.

2) To verify that the MS is able to perform a GPRS attach procedure on a forbidden PLMN in manual PLMN selection mode.

3) To verify that the MS after a successful GPRS attach procedure deletes the PLMN in the EFFPLMN on the SIM.

27.7a.4 Method of test

27.7a.4.1 Initial conditions

The SS transmits default message contents of Cell A, subclauses 40.1.1 and 40.2.1.1 on the BCCH, with the following exceptions:

RAI-MCC: 234

RAI-MNC 01 or 012 (see Note 0)

RAI-LAC: 0001

Access control: unrestricted.

Network Mode of Operation is set to NMO II.

The GPRS SIM is used with the following exception:

EFFPLMN (Forbidden PLMNs)

Logically: PLMN1: empty

PLMN2: empty

PLMN3: MCC: 234

MNC: 01 or 012 (See Note 0)

PLMN4: empty

The SIM is installed into the ME and the MS is set to automatic PLMN selection mode.

27.7a.4.2 Procedure

a) The MS is powered on.

b) PLMN with MCC/MNC of 234/01 or 234/012 (see Note 0) is manually selected.

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

d) After receipt of an ATTACH REQUEST from the MS, the SS sends ATTACH ACCEPT with:

RAI-MCC: 234

RAI-MNC 01 or 012 (see Note 0)

RAI-LAC 0001

RAI-RAC 05

P-TMSI: "D8765432"

P- TMSI signature value: "554433"

to the MS.

e) The MS is soft powered down.

27.7a.5 Test requirement

1) After step a) the MS shall not attempt a registration.

2) After step c) the MS shall send ATTACH REQUEST to the SS.

3) After step d) the MS shall respond with ATTACH COMPLETE.

4) After step e) the SIM shall contain the following values:

EFFPLMN (Forbidden PLMNs)

Logically: PLMN1: empty

PLMN2: empty

PLMN3: empty

PLMN4: empty
