Wireless GSM/GPRS AT Commands - PN S000293E 9 Chapter 1 – Introduction Scope of This Document This document describes the AT-command based messages exchanged between an application and the Multi-Tech Systems, Inc. products in order to manage GSM-related events or services. Related Documents This interface specification is based on the following recommendations: [1] ETSI GSM 07.05: Digital cellular telecommunications system (Phase 2); Use of DTE-DCE interface for Short Message Service (SMS) and Cell Broadcast Service (CBS) [2] ETSI GSM 07.07: Digital cellular telecommunications system (Phase 2); AT command set for GSM Mobile Equipment (ME) [3] ITU-T Recommendation V.25 ter: Serial asynchronous automatic dialing and control [4] ETSI GSM 03.40: Digital cellular telecommunications system (Phase 2); Technical implementation of the Short Message Service (SMS) Point-to-Point (PP) [5] ETSI GSM 03.38: Digital cellular telecommunications system (Phase 2); Alphabets and language-specific information [6] ETSI GSM 04.80: Digital cellular telecommunications system (Phase 2): Mobile radio interface layer 3, Supplementary service specification, Formats and coding Definitions The words, “Mobile Station” (MS) or “Mobile Equipment” (ME) are used for mobile terminals supporting GSM services. A call from a GSM mobile station to the PSTN is called a “mobile originated call” (MOC) or “outgoing call”, and a call from a fixed network to a GSM mobile station is called a “mobile terminated call” (MTC) or “incoming call”. In this document, the word “product” refers to any Multi-Tech product supporting the AT commands interface.](https://usermanual.wiki/Multi-Tech-Systems/92U07A31817/User-Guide-789840-Page-9.png)
![Chapter 5 – AT Call Control Commands Multi-Tech Systems, Inc. Wireless GSM/GPRS AT Commands - PN S000293E 17 Chapter 5 – AT Call Control Commands Dial Command D Description: The ATD command sets a voice, data or fax call. As per GSM 02.30, the dial command also controls supplementary services. For a data or a fax call, the application sends the following ASCII string to the product (the bearer must be previously selected with the +CBST command): ATD<nb> where <nb> is the destination phone number; For a voice call, the application sends the following ASCII string to the product: (the bearer may be selected previously, if not a default bearer is used). ATD<nb>; where <nb> is the destination phone number. Please note that for an international number, the local international prefix does not need to be set (usually 00) but does need to be replaced by the ‘+’ character. Example: to set up a voice call to Multi-Tech offices from another country, the AT command is: “ATD+17637853600;” Note that some countries/regions may have specific numbering rules for their GSM handset numbering. Values: <nb> Destination phone number <I> Optional parameter <I> means “invocation” (restrict CLI presentation) <i> Means “suppresssion” (allow CLI presentation) <mem> Phonebook (one of SM, LD, MC, ME, RC, MT or SN). A default value can be selected by +CPBS command. <index> Call number at indicated offset from the phonebook selected by the +CPBS command. <name> Call number corresponding to given name from the phonebook selected by the +CPBS command. The response to the ATD command is one of the following: Verbose result code Numeric code (with ATV0 set) Description OK 0 if the call succeeds, for voice call only CONNECT <speed> 10,11,12,13,14,15 if the call succeeds, for data calls only, <speed> takes the value negotiated by the product. BUSY 7 If the called party is already in communication NO ANSWER 8 If no hang up is detected after a fixed network time-out NO CARRIER 3 Call setup failed or remote user release. Use the AT+CEER command to know the failure cause Direct Dialing from a Phonebook (stored in the SIM card) can be performed with the following commands: ATD> <index>; to call <index> from the selected phonebook (by the +CPBS command) ATD> “BILL”; to call “BILL” from the selected phonebook ATD> mem <index> (mem is SM, LD, MC, ME, RC, MT or SN, see +CPBS command) allows direct dialing from a phonebook number. Does not function with ON mem. Syntax: ATD<nb>[<I>][;] ATD>[<mem>]<index>[<I>][;] ATD>[<mem>]<name>[<I>][;] Command Possible responses AT+CPBS?

It then tries to find the operator specified by the application and if found, tries to register. 2) The product is in automatic mode. It then tries to find the home operator and if found, tries to register. If not found, the product automatically searches for another network. 3) The product enters into manual/automatic mode, and then tries to find an operator as specified by the application (as in manual mode). If this attempt fails, it enters automatic mode. If this is successful, the operator specified by the application is selected. The mobile equipment then enters into automatic mode. Note: The read command returns the current mode and the currently selected operator. In manual mode, this PLMN may not be the one set by the application (as it is in the search phase). These commands are not allowed during one communication. Values: <mode> 0 automatic (default value) 1 manual 2 deregistration ; ME will be unregistered until <mode>=0 or 1 is selected. 3 set only <format> (for read command AT+COPS?) 4 manual / automatic (<oper> shall be present), if manual selection fails, automatic mode is entered. <format> <format>: format of <oper> field 0 long alphanumeric format <oper> 1 short alphanumeric format <oper> 2 numeric <oper> (default value) <stat>: status of <oper> <stat> 0 unknown 1 available 2 current 3 forbidden <oper>: operator identifier (MCC/MNC in numeric format only for operator selection) The long alphanumeric format can be up to 16 characters long (see Appendix A for operator names description, field is “Name”).

After the command has completed, the modem remains in V.25ter command state. If any PDP context is already in the requested state, the state for that context remains unchanged. If the requested state for any specified context cannot be achieved, an ERROR or +CME ERROR response is returned. Extended error responses are enabled by the +CMEE command. If the modem is not GPRS attached when the activation form of the command is executed, the modem first performs a GPRS attach and them attempts to activate the specified contexts. If the attach fails then the modem responds with ERROR or, if extended error responses are enabled, with the appropriate failure-to-attach error message. If no <cid>s are specified the activation form of the command activates the first activable defined contexts. If no <cid>s are specified the deactivation form of the command deactivates all active contexts. One PDP context can be activated at the same time. The read command returns the current activation states for all the defined PDP contexts. The test command is used for requesting information on the supported PDP context activation states. Values: <state>: indicates the state of PDP context activation 0 Deactivated 1 Activated Other values are reserved and will result in an ERROR response to the execution command. <cid>: a numeric parameter which specifies a particular PDP context.

This may include performing a GPRS attach and one PDP context activations. If the <cid> value is not defined to the modem, the modem will return an ERROR or +CME ERROR response. Otherwise, the modem issues the intermediate result code CONNECT and enters V.25ter online data state. GPRS attachment and PDP context activation procedures may take place prior to or during the PDP startup if they have not already been performed using the +CGATT and +CGACT commands. If no <cid> is given, the modem attempts to activate the context with whatever information is available to the modem. The other context parameters is set to their default values (No APN, default QOS parameters, dynamic IP address requested). If the activation is successful, data transfer may proceed. After data transfer and layer 2 protocol termination procedure completion, the V.25ter command state is re-entered and the modem returns the final result code OK. In case of an abnormal termination or start up, the V.25ter command state is re-entered and the modem returns the final result code NO CARRIER or, if enabled, +CME ERROR. Attach, activate and other errors may be reported. This command may be used in both normal and modem compatibility modes. Note: The goal of this command is the same than ATD*99***.

Values: <n> 0 Disable network registration unsolicited result code 1 Enable network registration unsolicited result code +CGREG: <stat> 2 Enable network registration and location information unsolicited result code +CGREG: <stat>[,<lac>,<ci>] <stat> 0 Not registered; the modem is not currently searching a new operator to which to register 1 Registered, home network 2 Not registered, but modem is currently searching a new operator to which to register 3 Registration denied 4 Unknown 5 Registered, roaming <lac> String type; two byte location area code in hexadecimal format <ci> String type; two byte cell ID in hexadecimal format Command Syntax: Command Possible response(s) AT+CGREG=[<n>] +CGREG: stat>[,<lac>,<ci>] OK AT+CGREG? +CGREG: <n>,<stat>[,<lac>,<ci>] OK Note: +CME ERROR: <err> AT+CGREG=? +CGREG: (list of supported <n>s) OK Request GPRS IP Service D Description: This command causes the modem to perform whatever actions are necessary to establish communication between the DTE and the external PDN. The V.25ter 'D' (Dial) command causes the modem to enter the V.25ter online data state and, with the DTE, to start the specified layer 2 protocol. The modem return CONNECT to confirm acceptance of the command prior to entering the V.25ter online data state. No further commands may follow on the AT command line. The detailed behavior after the online data state has been entered is described briefly in clause 9, for IP, of GSM 07.60. GPRS attachment and PDP context activation procedures may take place prior to or during the PDP startup if they have not already been performed using the +CGATT and +CGACT commands. If <cid> is supported, its usage is the same as in the +CGDATA command. The +CGDCONT, +CGQREQ, etc. commands may then be used in the modem initialization AT command string to set values for for PDP type, APN, QoS etc… If <cid> is not supported or is supported but omitted, the modem attempt to activate the context using the 'Empty PDP type' (GSM 04.08). (No PDP address or APN is sent in this case and only one PDP context subscription record is present in the HLR for this subscriber.) Values: <GPRS_SC_IP>: (GPRS Service Code for IP) a digit string (value 99), which identifies a request to use the GPRS with IP (PDP types IP and PPP) <cid>: a digit string which specifies a particular PDP context definition.

![Chapter 17 – GPRS Commands Multi-Tech Systems, Inc. Wireless GSM/GPRS AT Commands - PN S000293E 137 Automatic Response to a Network Request for PDP Context Activation +CGAUTO Description: The set command disables or enables an automatic positive response (auto-answer) to the receipt of a Request PDP Context Activation message from the network. It also provides control over the use of the V.25ter basic commands 'S0', 'A and 'H' for handling network requests for PDP context activation. The setting does not affect the issuing of the unsolicited result code RING or +CRING. The test command returns values of <n> supported by the modem as a compound value. When the +CGAUTO=0 command is received, the modem will not perform a GPRS detach if it is attached. Subsequently, when the modem announces a network request for PDP context activation by issuing the unsolicited result code RING or +CRING, the DTE may manually accept or reject the request by issuing the +CGANS command or may simply ignore the network request. When the +CGAUTO=1 command is received, the modem will attempt to perform a GPRS attach if it is not already attached. Failure will result in ERROR or, if enabled, +CME ERROR being returned to the DTE. Subsequently, when the modem announces a network request for PDP context activation by issuing the unsolicited result code RING or +CRING to the DTE, this is followed by the intermediate result code CONNECT. The modem then enters V.25ter online data state and follows the same procedure as it would after having received a +CGANS=1 with <cid> values specified. Values: <n> 0 Turn off automatic response for GPRS only For <n> = 0 GPRS network requests are manually accepted or rejected by the +CGANS command. 1 Turn on automatic response for GPRS only For <n> = 1 GPRS network requests are automatically accepted according to the description above. 2 Modem compatibility mode, GPRS only For <n> = 2, automatic acceptance of GPRS network requests is controlled by the 'S0' command. Manual control uses the 'A' and 'H' commands, respectively, to accept and reject GPRS requests. (+CGANS may also be used.) Incoming circuit switched calls can be neither manually nor automatically answered 3 Modem compatibility mode, GPRS and circuit switched calls (default) For <n> = 3, automatic acceptance of both GPRS network requests and incoming circuit switched calls is controlled by the 'S0' command. Manual control uses the 'A' and 'H' commands, respectively, to accept and reject GPRS requests. (+CGANS may also be used.) Circuit switched calls are handled as described elsewhere in this specification. Note: In class C GPRS the modem can’t receive GPRS and GSM incoming calls simultaneously.

![Chapter 17 – GPRS Commands Multi-Tech Systems, Inc. Wireless GSM/GPRS AT Commands - PN S000293E 138 Manual Response to a Network Request for PDP Context Activation +CGANS Description: The execution command requests the modem to respond to a network request for GPRS PDP context activation which has been signalled to the DTE by the RING or +CRING: unsolicited result code. The <response> parameter allows the DTE to accept or reject the request. If <response> is 0, the request is rejected and the modem returns OK to the DTE. If <response> is 1, the following procedure is followed by the modem. PDP context activation procedures take place prior to or during the PDP startup. One <cid> may be specified in order to provide the values needed for the context activation request. During the PDP startup procedure the modem has the PDP type and the PDP address provided by the network in the Request PDP Context Activation message. If a <cid> is given his informations must matching with the PDP type and PDP address in the network request as follows - The PDP type must match exactly. The PDP addresses are considered to match if they are identical or if the address in the context definition is unspecified. If any of this information is in conflict, the command will fail. The context is activated using the values for PDP type and PDP address provided by the network, together with the other information found in the PDP context definition. An APN may or may not be required, depending on the application. If no <cid> is given, the modem will attempt to activate the context using the values for PDP type and PDP address provided by the network, together with any other relevant information known to the modem. The other context parameters will be set to their default values. If the activation is successful, data transfer may proceed. After data transfer is complete, and the layer 2 protocol termination procedure has completed successfully, the V.25ter command state is re-entered and the modem returns the final result code OK. In the event of an erroneous termination or a failure to startup, the V.25ter command state is re-entered and the modem returns the final result code NO CARRIER or, if enabled, +CME ERROR. Attach, activate and other errors may be reported. It is also an error to issue the +CGANS command when there is no outstanding network request. This command may be used in both normal and modem compatibility modes. Values: <response>: is a numeric parameter which specifies how the request should be responded to. 0 reject the request 1 accept and request that the PDP context be activated If <response> is omitted it is assumed to be 0. Other values are reserved and will result in the ERROR response. <cid>: a numeric parameter which specifies a particular PDP context definition.
