WebAPI/WebSTK
From MozillaWiki
< WebAPI
Overview
To provide DOM API for the STK(SIM Toolkit), or CAT (Card Application Toolkit), which allows web contents can interact with SIM applications.
Status
Bugzilla : https://bugzilla.mozilla.org/show_bug.cgi?id=791161
Feature List: https://docs.google.com/spreadsheet/ccc?key=0AuvgnQ-Iwb6XdGV0aHZWdGdmZVEzZUxmZWNEaGJYWkE
Interface
- These interface will be added in MozIccManager
Event handlers for receiving messages from ICC to ME
These event handlers will be invoked when there are proactive commands or session end notification sent from ICC.
Proactive Command
/** * The 'stkcommand' event is notified whenever STK Proactive Command is * issued from ICC. */ attribute nsIDOMEventListener onstkcommand;
Session End Notificaiton
/** * 'stksessionend' event is notified whenever STK Session is terminated by * ICC. */ attribute nsIDOMEventListener onstksessionend;
Send Message from ME to ICC
There are two kinds of messages will be sent from ME to ICC
- Terminal Response
- Once the ME has made its attempt to execute a proactive command from the ICC, the ME shall inform the ICC of the success or otherwise of that command, by using TERMINAL RESPONSE.
- Envelope command
- Envelope command is used to transfer STK information from ME to ICC.
Send Terminal Response
/** * Send the response back to ICC after an attempt to execute STK Proactive * Command. * * @param command * Command received from ICC. See MozStkCommand. * @param response * The response that will be sent to ICC. * @see MozStkResponse for the detail of response. */ void sendStkResponse(in jsval command, in jsval response);
Send Envelope Command
Currently only support "Menu Selection", "Event Download"
/**
* Send the "Menu Selection" Envelope command to ICC for menu selection.
*
* @param itemIdentifier
* The identifier of the item selected by user.
* @param helpRequested
* true if user requests to provide help information, false otherwise.
*/
void sendStkMenuSelection(in unsigned short itemIdentifier,
in boolean helpRequested);
/**
* Send "Event Download" Envelope command to ICC.
* ICC will not respond with any data for this command.
*
* @param event
* one of events below:
* - MozStkLocationEvent
* - MozStkCallEvent
*/
void sendStkEventDownload(in jsval event);
STK message format
- TS 102.223, Annex C for the structure of STK communications
The specification of the message received from ICC and sent to ICC.
Basically, a STK message is of a BER-TLV object, which contains several Comprehension-TLV objects (TLV : Tag-Length-Value)
----- ----- ------------------------------------
BER-TLV | T | L | V - Several Comprehension-TLVs |
----- ----- ------------------------------------
/ \
/ \
----- ----- ----- ----- ----- -----
Comprehension-TLV | T | L | V | ... | T | L | V |
----- ----- ----- ----- ----- -----
Each STK message consists of at least two mandatory Comprehension-TLVs
- Command Details
- Device Identities
The remaining Comprehension-TLVs varies according to different type of STK message.
For the "Command Details" data object,
this data object shall be identical to the command details data object (including the comprehension required flag) given
by the UICC in the proactive command to which the terminal is giving the result.
And there two kinds of STK messages
- From ICC to ME
- MozStkCommand
- From ME to ICC
- MozStkResponse
In both MozStkCommand and MozStkResponse, we expose the content of 'Command Details' as:
- number
- type
- qualifier
So when a webapp tries to create a MozStkResponse, the webapp needs to create exactly the same 'Command Details' as it got from MozStkCommand.
From ICC to ME
The STK message sent from ICC to ME called 'Proactive Command'.
And we use MozStkCommand to represent 'Proactive Command'.
For example, a Proactive Command SET_UP_MENU whose Comprehension-TLVs will be looked like
---------------- -------------- ------------- ---------- ---------- | CmdDetails-TLV | DeviceId-TLV | AlphaId-TLV | Item-TLV | ... | Item-TLV | ---------------- -------------- ------------- ---------- ----------
- CmdDetails - Details of this proactive command.
- typeOfCommand is SET_UP_MENU
- DeviceId - The source and destination of this proactive command.
- AlphaId - The title of this menu
- Item - The items in this menu
In designing this message format, we wrap up the Comprehension-TLVs other than "Command Details" and "Device Identities" to a more high level UI component according to the typeOfCommand.
---------------- -------------- -------------- | CmdDetails-TLV | DeviceId-TLV | UI Component | ---------------- -------------- --------------
The UI componet includes
- Text Message
- Menu
- Input
- Call set up
- Launch Browser
So web apps can parse the UI componet according to the typeOfCommand.
In this case, web apps can display a Menu-like UI according to this UI component.
-------- | Title | -------- | Item 1 | -------- | Item 2 | --------
