| No | Command | Description |
| F1801 | AT+CLBS | Base station Location |
| F1802 | AT+CLBSCFG | Base station Location configure |
F1801 AT+CLBS Base Station Location
The write command is used to base station location.
| T) AT+CLBS=? |
+CLBS: (1,2,3,4,9),(1-42),(-180.000000-180.000000),(-90.000000-90.000000),(0,1) OK |
|
W) AT+CLBS=<type>,<cid>, [[<longitude>,<latitude>], [<lon_ type>]] |
OK 1) <type>=1,get longitude and latitude +CLBS: <ret_code>[,<latitude>,<longitude>,<acc>] 2) <type>= 2,get detail address +CLBS: <ret_code>[,<detail_addr>] 3) <type>= 3,get access times +CLBS: <ret_code>[,<times>] 4) <type>= 4,get longitude latitude and date time +CLBS: <ret_code>[,<latitude>,<longitude>,<acc>,<date>,<time>] 5) <type>= 9, report positioning error +CLBS: <ret_code> If error is related to ME functionality: +CLBS: <ret_code> ERROR |
| <type> | A numeric parameter which specifies the location type. 1 use 3 cell’s information 2 get detail address 3 get access times 4 get longitude latitude and date time 9 report positioning error |
| <cid> |
A numeric parameter which specifies a particular PDP context definition (see AT+CGDCONT command). 1…42 |
| <longitude> | Current longitude in degrees .-180.000000-180.000000 |
| <latitude> | Current latitude in degrees -90.000000-90.000000 |
| <detail_addr> |
Current detail address. It based the UCS2 coding. Each 4 characters in the URC is for one UCS2 character. |
| <acc> | Positioning accuracy |
| <lon_type> |
The type of longitude and latitude 0 WGS84 |
| <times> | Access service times(UTC,the format is YYYY/MM/DD,HH:MM:SS) |
| <date> | Service date(UTC, the format is YYYY/MM/DD). |
| <time> | Service time(UTC, the format is HH:MM:SS). |
| <ret_code> | Please refer to chapter 18.3 |
| Example |
AT+CLBS=? +CLBS: (1,2,3,4,9),(1-42),(-180.000000-180.000000),(-9 0.000000-90.000000),(0,1) OK AT+CLBS=1 OK +CLBS: 0,31.228525,121.380295,500 AT+CLBS=2 OK +CLBS: 0,4e0a6d775e020020957f5b81533a002091d19 49f8def002097608fd166688baf79d162805927697c AT+CLBS=3 OK +CLBS: 0,2020/04/30,09:48:56 AT+CLBS=4 OK +CLBS: 0,31.228525,121.380295,500,2025/06/07,10:49:08 |
NOTE
If customers feel that the positioning error is too large, <type>=9 can be used to report this information.
The error can be improved by this information. The LBS is only support in GSM/WCDMA/CDMA/LTE/5G net mode.
Before use LBS, please execute AT+NETACT? to check urc.
If return +NETACT: 0, please excute AT+NETACT=1 firstly; If return +NETACT: 1, excute LBS commands directly.
F1802 AT+CLBCFG Base station Location configure
The write command is used to set and query the base station location configure.
| T) AT+CLBSCFG=? |
+CLBSCFG: (0-1),3,”Param Value” OK |
| W) AT+CLBSCFG=<operate>,< para>[,<value>] |
+CLBSCFG: 0,<para>,<value> OK or OK If error is related to ME functionality: +CLBSCFG: <ret_code> ERROR |
| <operate> | 0 Read operator 1 Set operator |
| <para> | 3 Server’s address |
| <value> |
String type. The value of parameter Server’s address of “lbs-simcom.com:3002” is free |
| <len_value> | Please refer to chapter 18.3 |
| Example |
AT+CLBSCFG? +CLBSCFG: (0-1),3,”Param Value” OK AT+CLBSCFG=0,3 +CLBSCFG: 0,3,”lbs-simcom.com:3002″ OK |
