4.2.34 EFOCI (Outgoing Call Information)
31.1023GPPCharacteristics of the Universal Subscriber Identity Module (USIM) applicationRelease 17TS
If service n°8 is "available", this file shall be present.
This EF is located within the USIM application. The outgoing call information can be linked to the phone book stored under DFTELECOM or to the local phone book within the USIM. The EFOCI contains the information related to outgoing calls.
The time of the call and duration of the call are stored in this EF. It may also contain associated alpha identifier. In addition it contains identifiers of associated network/bearer capabilities and identifiers of extension records at the USIM ADF level. The structure of this file is cyclic, so the contents shall be updated only after a call is disconnected.
If the dialled phone number matches a number stored in the phone book the outgoing call information might be linked to the corresponding information in the phone book. The dialled number may match with a hidden entry in the phone book. If the dialled number matches a hidden entry in the phone book the link is established but the information related to the phone book entry is not displayed by the ME, if the hidden code has not been verified. The ME shall not perform hidden code verification at this point.
Optionally, the ME may store the link to phone book entry in the file, so that it does not need to look again for a match in the phone book when it reuses the entry. But the ME will have to check that the outgoing call number still exists in the linked phone book entry, as the link might be broken (entry modified). When not used by the ME or no link to the phone book has been found, this field shall be set to ‘FFFFFF’.
Coding scheme is according to EFICI.
