L1801   AT+CLBS     Base Station Location

The write command is used to base station location.

 

R) AT+CLBS=?

+CLBS:(list of supported <type>s), (range of supported <cid>s),

(range of supported <longitude>s),(range of supported <latitude>s),(list of supported <lon_type>s)

OK

W) AT+CLBS=<type>,<cid>,

[[<l ongitude>,<latitude>],

[<lon_ type>]]

1) <type>=1,get longitude and latitude

+CLBS: <locationcode>[,<latitude>,<longitude>,<acc>]

OK

2) <type>=4,get longitude latitude and date time

+CLBS:

<locationcode>[,<latitude>,<longitude>,<acc>,<date>,<time>]

OK

If error is related to ME functionality:

+CME ERROR: <err>

 

<type> 1 Use 3 cell’s information
4 Get longitude latitude and date time
<cid> Bearer profile identifier, refer to <pdpidx> of AT+CGDCONT
<locationcode>

0 Success

If the operation failed, the location code is not 0, such as:
1 Location Failed
2 Time Out
3 NET Error
4 DNS Error
5 Service Overdue
6 Authenticate Failed
7 Other Error
80 Report LBS to server success
81 Report LBS to server parameter error

<longitude> Current longitude in degrees .-180.000000-180.000000
<latitude> Current latitude in degrees  -90.000000-90.000000
<acc> Positioning accuracy
<lon_type>

The type of longitude and latitude

1 GCJ02

<date> Service date
<time> Service time

 

Example

AT+CLBS?

+CLBS:

(1,4),(1-24,100-179),(-180.000000-180.000000),

(-90.000000-90.000000),(0,1)

OK

 

 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

 

 

 

L1802   AT+CLBCFG     Base station Location configure

The write command is used to set and query the base station location configure.

T) AT+CLBSCFG=?

+CLBSCFG: (list of supported <operate>s),(range of supported

<para>s),<len_value>

OK

W) AT+CLBSCFG=<operate>,< para>[,<value>]

+CLBSCFG: 0,<para>,<value>

OK

OK

If error is related to ME functionality:

+CME ERROR: <err>

 

<operate> 0 Read operator
1 Set operator
<para>

3 Server’s address

lbs-simcom.com:3001

     lbs-simcom.com:3000

lbs-simcom.com:3002 (Default)

<value>

String type. The value of parameter

If <operate> is 1 and <para> is 3, <value> can be set.
