1 AT Commands for Remote-SAT in MC35

This document presents the specification for AT commands and responses required for the SIM Application Toolkit (SAT) implementation in MC35.

1.1 Introduction

SIM Application Toolkit (SAT) is a technology that lets the SIM card execute a great variety of additional applications. Conventionally, SIM cards are intended to store user specific data, such as phonebooks, secure user identification codes and messages, but they can also hold a lot of valueadded mobile applications.

The SAT functionality integrated in MC35 and MC35T allows to execute network specific applications implemented on the SIM card. Typical examples are online banking and information services.

The commands exchanged between SAT and the SIM application fall into two categories:

• Proactive commands – sent from the SIM application to the module’s SAT, e.g. DISPLAY TEXT.

• Envelope commands – sent from the module's SAT to the SIM application, e.g. MENU

SELECTION.

The SAT implementation supports SAT class 3, GSM 11.14 Release 98, no support of letter classes. GSM 11.14 describes Proactive and Envelope Commands in detail.

Note: The part on PC or PDA side which handles the Remote-SAT AT command interface (referred to as SAT-IF-Handler) is available as an exemplary implementation guidance as source code.

For details, please contact the Wireless Modules Application Engineering Department at Siemens AG.

1.1.3 Usage of Remote-SAT

Remote-SAT (RSAT) is designed as an AT interface that forms the link between the SIM application running on the SIM card and the customer application (PDA, laptop etc.). The purpose of RSAT is to allow the customer application to issue commands to the SAT interface and to display all SAT activities on the user interface of the customer application. To take advantage of Remote-SAT it must be explicitly started using the AT^SSTA command.

If no customer application is involved there is no need to communicate through the AT interface, and Remote-SAT can be ignored. In this case, all commands and responses may be exchanged directly between the module's SAT interface and the GSM network.

Both scenarios – whether or not Remote-SAT is activated – are illustrated in the context diagram in Chapter 1.1.2.

As a cellular module does not have an MMI, RSAT differs from a phone implementation of SAT. It uses a special set of AT Commands to pass data, e.g. a list of menu items, to the TA and to receive responses, e.g. a selected menu item.

The TA, being the customer application, is required to implement a state machine that controls the module's SAT. It monitors the states of SAT and sends appropriate AT commands when required, depending upon user input. As an example of a proven implementation approach, the SIEMENS PCMMI tool is available on request.

If the TA does not offer the SIM Application Toolkit to the end user, e.g. online banking, information services, then the module does not place any requirements on the TA for additional support. Therefore the state machine and the use of RSAT AT commands do not need to be implemented in the TA.

1.1.4 Command Type Values

The Command Type value (<cmdType>) identifies the type of command or associated response passed between the TA (customer application) and the ME.

<cmdType>) is the parameter that comes first in AT commands, in response to AT^SSTGI (see Chapter 1.4) and AT^SSTR (see Chapter 1.5), and in the ^SSTN unsolicited result code (see Chapter

1.3).

The SAT implementation supports SAT class 3 (GSM 11.14 Release 98, no support of letter classes). Therefore, Table 1 summarizes only those command types and parameters which may appear on the user interface (UI) and thus, allow the user to take an action. Command types that are transparent to the user are not listed in the table, although they are supported by Remote-SAT as specified in GSM

11.14.

1.1.5 Parameter Types

Strings are passed as UCS2 characters, usage of the GSM alphabet is also possible. However, use of the GSM alphabet is not recommended since a SIM can contain text which then is not displayable (e.g. Greek characters). To select the type of alphabet, use the AT^SSTA command. The type is determined both for inputs and outputs. UCS is specified in ISO/IEC 10646. There are 2 and 4 octet versions available, of which only the 2octet variant is used, known as UCS2. The 65536 positions in the 2-octet form of UCS are divided into 256 rows, each with 256 cells. The first octet of a character representation gives the row number, the second the cell number. The first row, row 0, contains exactly the same characters as ISO/IEC 8859-1. The first 128 characters are thus the ASCII characters. The octet representing an ISO/IEC 8859-1 character is easily transformed to the representation in UCS, by putting a 0 octet in front of it. UCS includes the same control characters as ISO/IEC 8859 and these are also in row 0. e.g. ’<x><x><n><n>’ <x><x> specifies the character set. <n><n> specifies the character.

1.1.6 States of Remote-SAT

The communication with the SIM Application Toolkit is performed via the AT commands detailed in the following chapters. In general, the type of AT command that can (and should) be issued depends on the current state of the Remote-SAT interface.

The current state of Remote-SAT is determined by

1. the application running on the SIM,

2. the application running on the TA (external controller),

3. the internal actions of the ME (especially SAT and Call Control).

1.1.6.2 Remote-SAT State Transition Table

The following table outlines which AT commands can be issued during certain states. However, the test and read AT commands are available at any time. So it is possible to determine the current state of the interface via AT^SSTA?. If a response contains text, the selected alphabet has to be used.

Meaning of options in column “M/O/X”: M: The TA has to issue the AT command to get Remote-SAT service (mandatory). O: Issue of the AT command is optional. X: Issue of the AT command is not allowed at this time and will lead to an error message.

1.1.7 Examples: Using Remote-SAT

To give you an idea of how to start and use Remote-SAT, you may follow the steps described below:

// Start after switch on the module

at OK

// Switch on verbose error messages

at+cmee=2 OK

// Enter the PIN code (if necessary due to SIM configuration)

at+cpin=1234 OK

// Ask if a SIM application is available and has started right now

at^ssta? ^SSTA: 1,1,1,"7FFFFFFF7F0100DF1F" OK

// OK, First ´1´ tells us that SIM application has started but interface is still in ´OFF´ state. // Tell the module that we are interested in SAT, i.e. switch to ´IDLE´ state.

at^ssta=1,0 OK

// Now we receive the first proactive command

^SSTN:37

// We have to ask for the parameter details

at^sstgi=37

// These are the details:

^SSTGI: 37,0,3,"SAT Special Menue",0,1,1,0 ^SSTGI: 37,1,"News",0,0 ^SSTGI: 37,2,"EMail",0,0 ^SSTGI: 37,3,"Banking",0,0

// We always have to acknowledge the proactive command

at^sstr=37,0

// SAT tells us that the proactive session has ended and enters its main menue (which should then be opened on the sreen by an MMI):

^SSTN:254

// Now we want to select item no. 1 of the menue sent before:

at^sstr=211,0,1

1.1.8 Sequence scenarios

In the following sequence diagrams dashed lines refer to events which respond to a formerly issued request.

1.1.8.1 Initialisation sequence

TA: ME: SIM:

Reset

Off

^SSTN: 255

Release Sim Application

AT^SSTA = 1,n

Idle

The SAT starts in the “Reset” state when the module powers up. In this state no SAT related AT commands can be issued or responses received. When the SIM Application is released SAT moves into the “Off” state.

When in the “Off” state a supported SIM Application exists on the SIM card. The TA receives an Unsolicited Result Code to indicate this and SAT can be activated now by activated by the TA.

Issuing the AT^SSTA command activates SAT and specifies the alphabet to be used. SAT then moves into the “Idle” state where it is then ready for use. When in “Idle” state SAT can receive input from the TA, such as forms of the AT^SSTR command.

Issue PAC

AT^SSTGI: <pac>

Wait

Idle

^SSTGI: <pac>,..values..

AT^SSTR: <pac>

TERMINAL RESPONSE: <pac>

Idle

^SSTN: 254

Upon receiving a Proactive command (PAC) from the SIM, SAT steps into the “PAC” state. The TA is informed that a PAC has been issued and is expected to respond with a request for further information. Whilst in the “PAC” state some forms of the AT^SSTR commands can be issued.

Upon receiving the AT^SSTGI command SAT changes into the “Wait” state. Further information about the PAC is sent to the TA and a response is required to trigger a TERMINAL RESPONSE back to the SIM Application.

SAT then moves back to the “Idle” state and either another PAC is issued or SAT informs the TA that the proactive session is over.

A SIM Application will provide SAT with Main Menu to display, using the PAC SETUP MENU. The Envelope Command MENU SELECTION allows the TA to select an item from this menu, via AT^SSTR.

When this takes place, SAT will issue a response to the user, but will not change the state. The SIM Application is then generally expected to issue a PAC.

RESPONSE

Envelope commands are issued for Call/MO Control by SAT if Call control is enabled. Upon receiving the response from the SIM Application SAT changes to the “PAC” state.

In the “PAC” state the TA is informed of the pending information and expected to issue AT^SSTGI to request further information. This sends SAT into the “Wait” state upon which is sends the relevant Call/MO Control information to the TA.

SAT then returns to its “Idle” state.

1.2 AT^SSTA Remote-SAT Activation

Test command

AT^SSTA=?

Response

^SSTA:(list of supported <state>s), (list of supported <alphabet>s)

Parameter description see below.

Read command

AT^SSTA?

The read command can be used to request the current operating status and the used alphabet of the Remote-SAT interface.

State handling is described in chapter “States of ”, pg. 9.

Response

^SSTA:<state>,<alphabet>,<allowedInstance>,<SatProfile>

<state> device is in one of the following state:

0 RESET

1OFF

2IDLE *)

3 PAC

4WAIT

*) Note:

Only this state can be selected directly by the TA, see write command.

0 SAT is already used on an other instance (logical channel in

case of the multiplex protocol). Only test and read commands can be used.

1 SAT may be started on this instance via the write version of

this command (see below).

SAT profile according to GSM 11.14, see appendix. The profile tells the SIM application which features are supported by the SIM Application Toolkit implemented by the ME. The profile cannot be changed by the TA.

Write command

AT^SSTA= <mode> [,<Alphabet>]

The write command activates the AT command interface to the SIM Application Toolkit in the ME. It must be issued each time the ME is switched on again. However, removing and inserting the SIM does not affect the activation status.

SAT commands which are not using the AT interface (non MMI related SAT commands , e.g. PROVIDE LOCAL INFORMATION) may be executed without activating Remote-SAT.

Parameter

<mode>

1 Activate Remote-SAT (to enter state IDLE)

0 GSM default alphabet (GSM 03.38)Input of a character

requests one byte , e.g. “Y”.

• On ME´s output of string parameter (e.g. ,”Examples”) character values will range from 32 to 255.

• On input to the ME only character values from 32 to 128 are accepted! Therefore input characters with GSM alphabet values outside this range have to be entered with an escape character and the hexadecimal value, e.g. “\00 is @”.

1 UCS2

To display the 16 bit value of characters represented in UCS2 alphabet a 4 byte string is required, e.g. “0059” is coding the character “Y”. For details please refer to ISO/IEC

10646.

1.3 ^SSTN Remote-SAT Notification

Proactive Commands

Every time the SIM application issues a proactive command, via the ME, the TA will receive a notification. This indicates the type of proactive command issued.

AT^SSTGI must then be used by the TA to request the parameters of the proactive command from the ME.

Upon receiving the ^SSTGI response from the ME, the TA must send AT^SSTR to confirm the execution of the proactive command and provide any required user response e.g. selected menu item.

Unsolicited result code

^SSTN: <cmdType>

Parameters

<cmdType> Proactive command ID, see Table 1- Command Type Identifiers

Note: Only one proactive command can be ongoing at any one time.

Terminate Proactive Command

When the SIM application has issued a proactive command, via the ME, to the TA, it is possible that this command must be terminated. The ^SSTN Unsolicited Result Code is sent but with a different command type (add terminate offset 100), to indicate the termination of the specified command.

The state changes to idle.

The TA should then avoid sending any further commands related to the terminated proactive command, e,g. AT^SSTGI or AT^SSTR.

Unsolicited result code

^SSTN: <cmdTerminateValue>

Parameters

<cmdTerminateValue> is defined as <cmdType> + terminate offset. The terminate offset equals 100.

Terminate proactive command ID, see Table 1- Command Type Identifiers

SIM Application returns to main menu

Notification to the TA when the SIM Application has finished a command cycle and again enters its main menue, which was transferred with an URC ^SSTN: 37 (SET UP MENU) at start up.

This URC should be used to open this menue on the sreen.

The TA does not need to respond directly, i.e. AT^SSTR is not required.

Unsolicited result code

^SSTN: <254>

1.4 AT^SSTGI Remote-SAT Get Information

1.4.1 AT^SSTGI Remote-SAT Get Information – Generic Format

Test command

AT^SSTGI=?

Response

^SSTGI:(list of supported <state>s), (list of supported <cmdType>s)

Read command

AT^SSTGI?

Response

^SSTGI: <state>, <cmdType>

Parameters

<state> Remote-SAT interface states (refer to AT^SSTA)

<cmdType> Ongoing Proactive Command (values see chapter 1.1.4

“Command Type Values”.). However, this information is valid during states PAC and WAIT only.

Write command

AT^SSTGI=

There are two situations for use of the Write command:

1. Regularly the Write command is used upon receipt of an unsolicited result code ^SSTN:<cmdType>. In this case the TA is expected to acknowledge the ^SSTGI response with AT^SSTR to confirm that the proactive command has been executed. AT^SSTR will also provide any user information e.g. selected menu item.

2. There may be the situation to request the information via AT^SSTGI without previously receiving an URC ^SSTN:<cmdType>. This will always be the case if the TA has started or restarted its application (e.g. a MMI) after power on the ME. To request the information despite the probably missed URCs it is possible to issue AT^SSTGI during states IDLE, PAC and WAIT at any time for the following Proactive Commands: PAC type 5: Set Up Event List, PAC type 37: Setup Menu, PAC type 40: Setup Idle Mode Test.

Note: In case of using the Write command without receipt of an unsolicited result code ^SSTN:<cmdType> it is neither necessary nor possible to acknowledge the ^SSTGI response with AT^SSTR. Such a ^SSTGI response will not cause any state changes.

The command type value is returned to the ME to identify which ^SSTN is being responded to.

Write command

AT^SSTGI=1

This command is to be used upon receiving an unsolicited result code

^SSTN:1.

The response from the module indicates the type of REFRESH that is going to be undertaken.

Response

^SSTGI: <cmdType>, <commandDetails> <CR> <LF>

Parameters

<cmdType> 1 – Proactive command ID, see Table 1 <commandDetails> Unsigned Integer, range 0 – 255, used as an

enumeration. 0 SIM Initialization and Full File Change

Notification; 1 File Change Notification; 2 SIM Initialization and File Change Notification; 3 SIM Initialization; 4 SIM Reset; ME is performing a SIM reset.

Therefore a Terminal Response should not be

issued. 5 to 255 = reserved values.

For every return value of <commandDetails> except 4 (SIM reset) the external application shall react as follows:

1. Issue the related Terminal Response AT^SSTR=1,<status>.

2. If <status> is 0 (Command performed successfully) the TA is requested to show a “Please wait” alert window on its screen until it will receive the RSAT notification ^SSTN:101 (Terminate proactive command REFRESH).

1.4.4 AT^SSTGI Remote-SAT Get Information – Setup Call (16)

Write command

AT^SSTGI=16

This command is to be used upon receiving an unsolicited result code ^SSTN:16.

If the SIM Application attempts to setup a call it uses this response to inform the TA of the call´s parameters. The sequence of events is as follows:

1. After the Remote-SAT notification 16 was issued the TA has to to ask for the command parameter via AT^SSTGI=16.

2. If the SIM Application supplies no confirmation text or icon parameter, the TA gives other information to the user, e.g. the telephone number. In this case flow continues at step 4.

3. If the SIM Application supplies a non empty confirmation text or icon parameter, the TA uses only these to ask the user whether he like to setup the call or not.

4. If the user confirms to setup the call, AT^SSTR=16,0 shall be responsed.

5. If the user denies to setup the call, AT^SSTR=16,34 shall be responsed.

6. After confirmation phase the TA may show a dialling animation on the screen until a mandatory URC ^SSTR: 16, <TermQualifier>, <TerminationCauseText> is issued.

7. If <TermQualifier> is not equal to 0 the dialling process did not perform sucessfully. If <TerminationCauseText> is not an empty string, this text has to be shown to the user for an appropriate time, e.g. 2 seconds. The text contains information regarding the dial termination cause, e.g. call barring through Call Control by SIM mechanism. <TerminationCauseText> is an empty string, the TA shall give an own indication to the user.

8. If <TermQualifier> is equal to 0, the dial process has been successfully finished.

9. After this the TA shall show the call setup text and/or icon to the user, if supplied by the SIM. This information may be shown during the call.

10. The TA shall give the user an opportunity to end an ongoing call, setup by the Proactive Command. In this case the TA shall issue an ATH command to the ME.

Response

^SSTGI: <cmdType>, <commandDetails>, <confirmationText>,

Parameters

1.5 AT^SSTR Remote-SAT Response – Generic Format

Test command

AT^SSTR=?

Response

^SSTR:(list of supported <state>s), (list of supported <cmdType>s)

Read command

AT^SSTR?

Response

^SSTR: <state>, <cmdType>

Parameters

<state> Remote-SAT interface states (refer to AT^SSTA)

<cmdType> Ongoing Proactive Command (values see chapter 1.1.4

“Command Type Values”). However, this information is valid during states PAC and WAIT only.

Write command

AT^SSTR= <cmdType>, <status> [,<itemId>] [,<inputString>]

The TA is expected to acknowledge the ^SSTGI response with AT^SSTR to confirm that the proactive command has been executed. AT^SSTR will also provide any user information e.g. selected menu item.

Response

If an error occurs during execution of a Proactive Command, the process can be halted and a Terminte Command Information will be signalled.

^SSTR: 16, <TermQualifier>, <TerminationCauseText>

<TerminationQualifier> Unsigned Integer, range 0 – 255 0 If <TerminationQualifier> is equal to 0, the Proactive Command has

been successfully finished.

>0 If <TerminationQualifier> is not equal to 0 the Proactive Command

did not perform sucessfully.

If < TerminationQualifier > is not equal to 0 and <TerminationCauseText> is not an empty string, this text has to be shown to the user for an appropriate time, e.g. 2 seconds. The text contains information regarding the termination cause, e.g. call barring through Call Control by SIM mechanism. If < TerminationQualifier > is not equal to 0 and <TerminationCauseText> is an empty string, the TA shall give an own indication to the user.

Parameters

<cmdType> Number related to Proactive command or event type, see table

1.1.4 Command Type Values, pg. 7.

<status> Command status return regarding the type of action that has taken

place, e.g. action performed by the user, possible values see the following table 1.5.1 Remote-SAT Command Status, pg. 41.

1.5.3.5 AT^SSTR Remote-SAT Event Response – Terminate Command (254)

Write command

AT^SSTR=254

This command allows the TA to finish an ongoing proactive command, if any. This is done by sending a Terminal Response “ME currently unable to process command - screen is busy” to the SIM (see table “Remote-SAT Command Status”, pg. 41), if issued in states PAC or WAIT. No action is performed if the interface is already in IDLE state. However, command returns “OK”.

The actual reaction regarding the Terminal Response depends on the SIM application.

The command can be used to return to IDLE state regardless whether a Proactive command is ongoing or not.

Response

Parameters

<cmdType> 254 – Event command ID, see Table 1

Reference

Siemens

Note

This command is allowed in states IDLE, PAC and WAIT and forces a return to IDLE state once it has been issued successfully, i.e. OK response.

2 Appendix

2.1 Appendix A – SAT Profile

SAT Profile download is used as a means of the ME telling the SIM what it is capable of. The Profile download instruction is sent to the SIM from the ME as part of the SIM initialisation process. The profile sent by the ME states which facilities the ME will support.

The SIM adapts its behavior to the capabilities of the ME by reducing its instruction range.

The AT command AT^SSTA is used to read the profile, please refer to chapter 1.2 AT^SSTA RemoteSAT Activation, pg. 19.

For further information please refer to GSM 11.14 section 5.2.
