Command Possible response(s)
+CHLD=<n> +CME ERROR: <err>
+CHLD=? +CHLD: (list of supported <n>s)
Description
This command allows the control of the following call related services:
  • a call can be temporarily disconnected from the MT but the connection is retained by the network;
  • multiparty conversation (conference calls);
  • the served subscriber who has two calls (one held and the other either active or alerting) can connect the other parties and release the served subscriber's own connection.
Calls can be put on hold, recovered, released, added to conversation, and transferred similarly as defined in TS 22.030. Refer clause 9.2 for possible <err> values.
This is based on the supplementary services HOLD (Call Hold; refer TS 22.083, clause 22.083 [5] clause 2 and TS 24.610), MPTY / CONF (MultiParty; refer TS 22.084 and Conference; refer TS 24.605) and ECT (Explicit Call Transfer; refer TS 22.091 and TS 24.629).
Test command returns a list of operations which are supported. The call number required by some operations shall be denoted by "x" (e.g. +CHLD: (0,1,1x,2,2x,3)).

Description
This command allows control of the Unstructured Supplementary Service Data (USSD) according to TS 22.090, TS 24.090 and TS 24.390. Both network and mobile initiated operations are supported. Parameter <n> is used to disable/enable the presentation of an unsolicited result code. The value <n>=2 is used to cancel an ongoing USSD session. For an USSD response from the network, or a network initiated operation, the format is: +CUSD: <m>[,<str>,<dcs>].
When <str> is given, a mobile initiated USSD-string or a response USSD-string to a network initiated operation is sent to the network. The response USSD-string from the network is returned in a subsequent unsolicited +CUSD result code. Refer clause 9.2 for possible <err> values.
The interaction of this command with other commands based on other supplementary services is described in the specification of the relevant supplementary service.
Read command returns the current value of <n>.
Test command returns values supported as a compound value.

<str>
string type USSD-string (when <str> parameter is not given, network is not interrogated):
  • if <dcs> indicates that TS 23.038 7 bit default alphabet is used:
    • if TE character set other than "HEX" (refer command select TE character set +CSCS): MT/TA converts GSM alphabet into current TE character set according to rules of TS 27.005 Annex A
    • if TE character set is "HEX": MT/TA converts each 7-bit character of GSM alphabet into two IRA character long hexadecimal number (e.g. character  (GSM 23) is presented as 17 (IRA 49 and 55))
  • if <dcs> indicates that 8-bit data coding scheme is used: MT/TA converts each 8-bit octet into two IRA character long hexadecimal number (e.g. octet with integer value 42 is presented to TE as two characters 2A (IRA 50 and 65))
  • if <dcs> indicates that 16-bit data coding scheme (UCS2) is used: MT/TA splits the 16 bits into two 8-bit octets. Each of those octets are converted as per the 8-bit data coding scheme, with the most significant octet first (e.g. decimal value 4906 is presented to TE as four characters 132A (IRA 49, 51, 50 and 65))

Description
This refers to Advice of Charge supplementary service (TS 22.024 and TS 22.086) that enables subscriber to get information about the cost of calls. With <mode>=0, the execute command returns the current call meter value from the MT.
The command also includes the possibility to enable/disable reporting of the CCM information with unsolicited result code +CCCM: <ccm>. When enabled, this unsolicited result code is sent when the CCM value changes, but not more frequently than at every 10 seconds.

Read command indicates whether the unsolicited reporting is activated or not.
Test command returns the supported mode values as a compound value.

+CSSN=[<n>[,<m>]]
+CSSN? +CSSN: <n>,<m>
+CSSN=? +CSSN: (list of supported <n>s),(list of supported <m>s)
Description
This command refers to supplementary service related network initiated notifications. The set command enables/disables the presentation of notification result codes from TA to TE.
When <n>=1 and a supplementary service notification is received after a mobile originated call setup, intermediate result code +CSSI: <code1>[,[<index>][,<SS_code>]] is sent to TE before any other MO call setup result codes presented in the present document or in ITU-T Recommendation V.250 [14]. When several different <code1>s are received from the network, each of them shall have its own +CSSI result code.
When <m>=1 and a supplementary service notification is received during a mobile terminated call setup or during a call, or when a forward check supplementary service notification is received, unsolicited result code +CSSU: <code2>[,<index>[,[<number>],[<type>][,[<subaddr>],[<satype>]][,<SS_code>]]] is sent to TE. In case of MT call setup, result code is sent after every +CLIP result code (refer command Calling line identification presentation +CLIP) and when several different <code2>s are received from the network, each of them shall have its own +CSSU result code. <code2>=5 does not reflect any supplementary service, and the parameter <SS_code> will not be provided.
The supplementary service notification can also be reported in unsolicited result codes +CMCCSS<x> / +CMCCSSEND, enabled with +CMCCS=3 (see AT command monitor of current calls +CMCCS). The unsolicited result codes +CMCCSS<x> / +CMCCSSEND support numbers of the SIP URI format.

Description
This command is used to edit the PLMN selector with Access Technology lists in the SIM card or active application in the UICC (GSM or USIM).
Execute command writes an entry in the SIM/USIM list of preferred PLMNs, previously selected by the command +CPLS. If no list has been previously selected, the User controlled PLMN selector with Access Technology, EFPLMNwAcT, is the one accessed by default. If <index> is given but <oper> is left out, entry is deleted. If <oper> is given but <index> is left out, <oper> is put in the next free location. If only <format> is given, the format of the <oper> in the read command is changed. The Access Technology selection parameters, <GSM_AcT>, <GSM_Compact_AcT>, <UTRAN_AcT>, <E-UTRAN_AcT> and <NG-RAN_AcT> are required when writing User controlled PLMN selector with Access Technology, EFPLMNwAcT, Operator controlled PLMN selector with Access Technology EFOPLMNwAcT and HPLMN selector with Access Technology EFHPLMNwAcT, see TS 31.102. Refer clause 9.2 for possible <err> values.
Read command returns all used entries from the SIM/USIM list of preferred PLMNs, previously selected by the command +CPLS, with the Access Technologies for each PLMN in the list.
Test command returns the whole index range supported by the SIM as compound values.
