Falkenber9 gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder, laforge, fixeria, dexter, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/pysim/+/23632 to look at the new patch set (#10). Change subject: WIP: Add option to set UE operation mode in EF_AD (Administrative Data) ...................................................................... WIP: Add option to set UE operation mode in EF_AD (Administrative Data) Use ``--opmode=OPMODE`` in cmdline mode or column ``OPMODE`` in csv mode to specify OPMODE as listed below. Details: The ``EF_AD`` field contains administrative data (AD). It consists of four bytes ``B1``, ``B2``, ``B3``, ``B4``, and optionally further bytes for future use. Previous implementation only sets the MNC field appropriately (located in `B4`) and sets all other bits/bytes to 0. However, `B1` also defines the *UE operation mode* (see below). For type approval operations, such as testing with a test uSIM, this value could be set to `0x80` rather than `0x00`(= normal operation). This may unlock some UE capabilities that are restricted in normal operation mode. Excerpt from [ETSI TS 131 102, 4.2.18](https://www.etsi.org/deliver/etsi_ts/131100_131199/131102/04.15.00_60/ts_131102v041500p.pdf): ``` B1 - UE operation mode: Coding: Initial value - '00' normal operation. - '80' type approval operations. - '01' normal operation + specific facilities. - '81' type approval operations + specific facilities. - '02' maintenance (off line). - '04' cell test operation.
