The meaning of some items in Qualcomm Mobile NV

1. Tdscdma_op_plmn_list
<nvefsitem fullpathname= "/nv/item_files/modem/nas/tdscdma_op_plmn_list" name= "UNKNOWN" mapping= "direct" encoding= "Dec" index= "0" > 4,100,240,0,100,240,32,100,240,112,100,240,128,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ,0,0,0,0,0,0,0,0,0,0,0</nvefsitem>

4,100,240,0,100,240,32,100,240,112,100,240,128, change to 16 binary Yes

0x03 0x64 0xf0 0x00 0x64 0xf0 0x20 0x64 0xf0 0x70 0x64 0xf0 0x80

Reference: Http://www.cnblogs.com/bastard/archive/2013/05/09/3068602.html, which mentions 0x03 0x64 0xf0 0x00 0x64 0xf0 0x20 0x64 0xf0 0x70 (46000, 46002, 46007)

Then the whole representation: 4 items, respectively 46000, 46002, 46007, 46008

Nv65602:location–/nv/item_files/modem/nas/ehplmn

Default value–0x03 0x64 0xf0 0x00 0x64 0xf0 0x20 0x64 0xf0 0x70 (46000, 46002, 46007)     

Nv70189:location–/nv/item_files/modem/nas/tdscdma_op_plmn_list

Default value–0x03 0x64 0xf0 0x00 0x64 0xf0 0x20 0x64 0xf0 0x70 (46000, 46002, 46007)

The modem code deals with functions related to PLMN:

Reg_sim.c:reg_sim_read_ehplmn_list

2. Rat_acq_order

Company solution Call M Unable to answer the question, this NV item is adjusted to
<nvefsitem fullpathname= "/sd/rat_acq_order" name= "UNKNOWN" mapping= "direct" encoding= "Dec" index= "0" > 0,8,0,6,9,11,3,5,2,4,0,0,0,0</nvefsitem>

Combining code

0,8,0,6,9,11,3,5,2,4,0,0,0,0 probably understood: 8 items, No_srv, GPS, LTE, TDS, GSM, WCDMA, CDMA, HDR. Seems to be the Internet search order. TDS is estimated to be tdscdma, that is, except for GPs, and then 4g/3g/2g (for mobile).
