Terminal Response

• OPEN CHANNEL <-- Channel Identifier

ProactiveResponseHandler ProRespHdlr; // get the system instance
ProRespHdlr = ProactiveResponseHandlerSystem.getTheHandler();
ChannelID = ProRespHdlr.getChannelIdentifier() ;

• SEND DATA <-- Channel Data Length
• CLOSE CHANNEL <-- OK
• GET CHANNEL STATUS <-- Channel Status
• RECEIVE DATA <-- Channel Data Length , Data

ProactiveResponseHandler ProRespHdlr; // get the system instance
ProRespHdlr = ProactiveResponseHandlerSystem.getTheHandler();
ProRespHdlr.findTLV(TAG_CHANNEL_DATA ,0);
sOffset= ProRespHdlr.copyChannelData(byte[] dstBuffer, short dstOffset, short dstLength) ;
ProRespHdlr.findTLV(TAG_CHANNEL_DATA_LENGTH ,0);
datalength=ProRespHdlr.getValueVyte((short)0x0000);

CLOSE CHANNEL BIP

After OPEN Channel, You should know how to close it. Here are some important things you should be aware.

1. Command details*
   
1. command details tag = '81'
   
2. length = '03' (1 byte)
3. command number 01 - FE (1 byte)
4. Type of Command ='41' (CLOSE CHANNEL)
5. Command Qualifier :
   
• RFU for BIP Client Mode
• bit 1
• 0 : close TCP Connection and go to "TCP in CLOSED state"
• 1 : close TCP Connection and go to "TCP in LISTEN state"
2. Device identities*
1. device identities tag = '82'
   
2. Length = '02'
3. Source Device identity = '81' --> UICC
   
4. Destination Device Identity = '21'-'27' --> channel ID (PRE_ID _CHANNEL_BASE='20')
   
3. Alpha Identifier
1. Alpha identifier TAG = '05'
   
2. Length = 0
3. Alpha Identifier (TS 131 102)
   
4. Icon Identifier
   
1. Icon Identifier Tag
2. Length = '02'
3. Icon Qualifier
1. bit 1, 0 = self explanatory, 1 = non self explanatory
2. bit 2-8 =0 (RFU)
   
4. Icon Identifier (TS 131 102)
5. Text Attribute
1. Text Attribute Tag = '50'
2. Length
3. Text formatting ( TS 123 040)
   
6. Frame Identifier
1. Frame Identifier Tag
   
2. Length = '03'
3. Identifier of Frame, the value is between '00' - '0F'

You don't need to remember the tag value if you use appendTLV function. All of the tag value are explained briefly in uicc.toolkit.ToolkitConstant library.

note :
* mark means mandatory
Channel indentifier must be valid
