Commands
5.27. +CRLA Command: Restricted UICC Logical
Channel Access
HL7518 and HL7548
Write command
Syntax
AT+CRLA=
<sessionid>,
<command>
[,<file id>[,<P1>,
<P2>,<P3>
[,<data>
[,<pathid>]]]]>
Response
+CRLA: <sw1>,<sw2>[,<response>]
OK
or
+CME ERROR: <err>
Parameters
<sessionid> Integer typewhich identifies the session to be used in order to send the APDU
commands to the UICC. It is mandatory to send commands to the UICC when targeting
applications on the smart card using a logical channel other than the default channel
(channel "0").
<command> 176 READ BINARY
178 READ RECORD
192 GET RESPONSE
214 UPDATE BINARY
220 UPDATE RECORD
242 STATUS
219 SET DATA
All other values are reserved
<fileid> Integer type that identifies the elementary datafile on SIM. Mandatory for
every <command> except STATUS.
<P1>, <P2>, <P3> Integer type; parameters passed on by the MT to the UICC. These
parameters are mandatory for every command, except GET RESPONSE and STATUS.
<data> Information which shall be written to the SIM in hexadecimal format
<pathid> String type containing the path of an elementary file on the UICC in
hexadecimal format.
<sw1>, <sw2> Integer type; information from the UICC about the execution of the
actual command. These parameters are delivered to the TE in both cases, on successful or
failed execution of the command
<response> Response of a successful completion of the command previously issued in
hexadecimal format. STATUS and GET RESPONSE returns data, which gives information
about the current elementary datafield. This information includes the type of file and its size
(refer to 3GPP TS 31.101). After READ BINARY, READ RECORD or RETRIEVE DATA
command the requested data will be returned.
Notes
By using this command instead of generic UICC access command, +CGLA, the TE
application has an easier but more limited access to the UICC database.
