4.2.59 EF_OPL (Operator PLMN List)

31.1023GPPCharacteristics of the Universal Subscriber Identity Module (USIM) applicationRelease 17TS

If service n°46 is "available", this file shall be present.

This EF contains a prioritised list of Location Area Information (LAI) or Tracking Area Identity (TAI) identities that are used to associate a specific operator name contained in EF_PNN or EF_PNNI with the LAI/TAI. The ME shall use this EF in association with the EF_PNN in place of any network name stored within the ME’s internal list and any network name received when registered to the PLMN, as defined by TS 24.008 [9] or TS 24.301 [51]. The PLMN Network Name may also be provided in a graphical format in EF_PNNI. The ME shall use the text format or the graphical format or both to display the service provider name according to the rules defined in clause 4.2.89.

– Location Area Identity/Tracking Area Identity

Contents:
Location Area Information, this comprises of the MCC, MNC and LAC

Tracking Area Identity, this comprises of the MCC, MNC and TAC

Coding:
PLMN : according to TS 24.008 [9]/TS 24.301 [51]
A BCD value of ‘D’ in any of the MCC and/or MNC digits shall be used to indicate a "wild" value for that corresponding MCC/MNC digit

LAC/TAC : according to TS 24.008 [9]/TS 24.301 [51]

Two values for the LAC/TAC are stored in order to allow a range of LAC/TAC values to be specified for a given PLMN. A value of ‘0000’ stored in bytes 4 to 5 and a value of ‘FFFE’ stored in bytes 6 to 7 shall be used to indicate the entire range of LACs/TACs for the given PLMN. In the case where only a single LAC/TAC value is to be specified then the value stored in bytes 4 to 5 shall be identical to the value stored in bytes 6 to 7 for the given PLMN. If a range of LAC/TAC values are to be specified, then the value stored in bytes 4 to 5 shall be the start of the LAC/TAC range and the value stored in bytes 6 to 7 shall be the end of the LAC/TAC range for the given PLMN.

– PLMN Network Name Record Identifier

Contents:
Identifier of operator name to be displayed

Coding:
A value of ’00’ indicates that the name is to be taken from other sources, see TS 22.101 [24]

A value in the range ’01’ to ‘FE’ indicates the record number in EF_PNN that shall be displayed as the registered PLMN name. It also indicates the record number in EF_PNNI that may be displayed as the registered PLMN name icon.

NOTE: The intent of this file is to provide exceptions to the other sources of a network name. Care should be taken not to introduce too many PLMN entries. An excessive number of entries could result in a longer initialisation period.
