quecLocator in mc60

Hello. I’m using Quectel mc60 module. I want to use QuecLocator feature. I do this following process: AT+QIFGCNT=0
Ok
AT+QICSGP=1,“CMNET”
ok
AT+QIREGAPP
ok
AT+QIACT:
Ok
AT+QCELLLOC=1
+CME ERROR: http data decode error
When I send AT+QCELLLOC=1 the module response me “+CME ERROR: http data decode error” . why this error has happened and how can I fix it.
