[PATCH uqmi] nas: add decoding of cell_id

Henrik Ginstmark henrik at ginstmark.se
Tue Dec 7 12:53:57 PST 2021


Add decoding of lte_system_info_v2.cid, in --get-system-info, and
intrafrequency_lte_info_v2.global_cell_id, in --get-cell-location-info,
to enodeb_id and cell_id.
h´xxxxxyy -> enodeb_id = h´xxxxx, cell_id = h´yy

Add decoding of wcdma_system_info_v2.cid, in --get-system-info, to
rnc_id and cell_id.
h´xxxxyyyy -> rnc_id = h´xxxx,  cell_id = h´yyyy

Change order to
mcc-mnc-tac/lac-enodeb_id/rnc_id-cell_id.
