Set command enables and disables reporting of primary notification events when received from the network with unsolicited result code +CPNERU: <message_identifier>,<serial_number>,<warning_type>. Primary notification events are used for public warning systems like ETWS (Earthquake and Tsunami Warning Systems). When <reporting>=1, duplicate primary notifications will be discarded by the UE. Read command returns the current settings. Test command returns supported values as a compound value. Refer to clause 9.2 for possible <err> values.

<reporting> <message_identifier> <serial_number> <warning_type>

Optional.

The set command controls the presentation of an unsolicited result code +CIREGU: <reg_info>[,<ext_info>] when there is a change in the MT's IMS registration information. Refer to clause 9.2 for possible <err> values. The read command returns <n>, that shows whether reporting is enabled or disabled, <reg_info> that shows whether one or more of the public user identities are registered and optionally <ext_info>, that shows the status of the MT's IMS capabilities. For <ext_info>, all relevant values are always summarized and reported as a complete set of IMS capabilites in the unsolicited result code. The test command returns the supported values for <n> as a compound value.

<n> <reg_info> <ext_info>

Optional.

Set command informs the MT whether the UE is currently available for SMS using IMS (see TS 24.229). In EPS, the information can be used by the MT to determine the need to remain attached for non-EPS services, as defined in TS 24.301. In 5GS, the information can be used by the MT to determine whether to use SMS over IMS or SMS over NAS. Read command returns the UE's SMS using IMS availability status, as stored in the MT. Test command returns supported values as a compound value.

<state>

Optional.

This command activates or deactivates a call monitoring function in the ME. When this function is activated in the ME, the ME informs about events for calls with unsolicited result codes. The purpose of the call monitoring function is to:

1. gather relevant information for the detected calls in a TE; and
2. make it possible for the TE to display call state information for ongoing calls.

The unsolicited result code+CMCCSI is used for basic call information. +CMCCSI: <ccidx>,<dir>,<neg_status_present>,<neg_status>,<SDP_md>,<cs_mode>,<ccstatus>,<mpty>,<numbertype>,<ton>,<number>,<exittype>,<exitcause> The unsolicited result code +CMCCSI is provided when <n>=2. For an originating call, the parameters <numbertype>, <ton> and <number> in +CMCCSI provide the number (line identity) information which has been dialled with +CDU or ATD. For a terminating call, the parameters <numbertype>, <ton> and <number> in +CMCCSI provide the number (line identity) information of the calling user. The unsolicited result codes +CMCCSS<x> / +CMCCSSEND are used for supplementary service related information. +CMCCSS1: <ccidx>,<dir>,<service> [+CMCCSS2: <numbertype>,<ton>,<number>] [+CMCCSS3: <CLI_validity>] [+CMCCSS4: <name>] [+CMCCSS5: <subaddr>,<satype>] [+CMCCSS6: <priority>] [+CMCCSS7: <CUG_index>] [+CMCCSS8: <eCNAM_meta>] +CMCCSSEND The unsolicited result codes +CMCCSS<x> / +CMCCSSEND are used for supplementary service related information and are reported when <n>=3. For every supplementary service related event, the unsolicited result codes +CMCCSS<x> shall be given in consecutive order, and the sequence of unsolicited result codes shall be terminated by +CMCCSSEND. It is manufacturer specific when and if this additional service reporting will be issued. Whenever a service event is to be reported using these unsolicited result codes, the codes +CMCCSS1 and +CMCCSSEND are mandatory. +CMCCSS1 contains essential information that is always needed (for example <ccidx>) and +CMCCSSEND indicates the end of this particular set of unsolicited result codes. The other unsolicited result codes (+CMCCSS2 to +CMCCSSn) are optional, intended to provide information related to a given service. E.g. for the supplementary service CNAP, the unsolicited result code +CMCCSS4 (containing <name>) may be issued. It is implementation specific which of the unsolicited result codes +CMCCSS<x> / +CMCCSSEND that are supported and provided to the TE. The unsolicited result codes should be provided to the TE as soon as the information is available in the ME. The parameters <numbertype>, <ton> and <number> in +CMCCSS2 are, if applicable, normally the line identity information that is related to the parameter <service>. A subset of the information provided by the call monitoring function can be provided by the command +CLCCS. When the unsolicited result code +CMCCSI report that the <ccstatus>=1 (Idle), the call identification number is reset and the call identification number <ccidx> can be used by new calls. The logic for reuse of the parameter <ccidx> is implementation specific. Read command returns the current value of <n>. Test command returns the values supported as a compound value.

<n> <x> <ccidx> <dir> <neg_status_present> <neg_status> <SDP_md> <cs_mode> <ccstatus> <mpty> <numbertype> <ton> <number> <exittype> <exitcause> <service> <CLI_validity> <name> <subaddr> <satype> <priority> <CUG_index> <eCNAM_meta>

Optional.

Returns a list of current calls controlled by the MT for which the <ccidx> is allocated. The information returned is a subset of the information provided by the call monitoring function, see +CMCCS and its unsolicited result codes +CMCCSI and +CMCCSS<x> / +CMCCSSEND. For an originating call, the parameters <numbertype>, <ton> and <number> provide the number (line identity) information which has been dialled with +CDU or ATD. For a terminating call, the parameters <numbertype>, <ton> and <number> provide the number (line identity) information of the calling user. If no particular <ccidx> is included in the request, data for all allocated <ccidx> are returned. If the command succeeds but no <ccidx> is allocated, no information response is sent to the TE. Refer to clause 9.2 for possible <err> values.

<ccidx> <dir> <neg_status_present> <neg_status>: integer type as defined in the +CCMMD command. 0 1 2 3 4 <SDP_md> <ccstatus> <mpty> <numbertype> <ton> <number> <priority_present> <priority> <CLI_validity_present> <CLI_validity>

Optional. This command supports all types of numbers (including SIP URIs) and can replace +CLCC.

Set command is used to configure the availability of the radio accesses inherently supported by the MT. E.g. in a GSM-only environment, other radio access technologies could be disabled to reduce power-consumption. Settings are persistent over a power-cycle. It is not supported to set all parameters to indicate "Radio access is disabled", this will cause the MT to return ERROR. +CSRA only configures the requested parameters; no change in the transmit and receive RF circuits takes place by using +CSRA. The actual execution of the configuration is obtained by using +CFUN=128. Read command returns two lines of information text with two distinct prefixes:

• a line prefixed with +CSRAC: displaying the currently configured +CSRA settings. These values are not activated until +CFUN=128 is executed, and this line does therefore not necessarily reflect the RATs currently activated on the radio interface; and
• a line prefixed with +CSRAA: displaying the RATs currently activ on the radio interface.

Read command returns the current settings in the MT. Refer to clause 9.2 for possible <err> values. Test command returns values supported by the MT as compound values. The returned values do not reflect network capabilities.

<GERAN-TDMA> <UTRAN-FDD> <UTRAN-TDD-LCR> <UTRAN-TDD-HCR> <UTRAN-TDD-VHCR> <E-UTRAN-FDD> <E-UTRAN-TDD> <NR-FDD> <NR-TDD>

Optional. Mandatory when +CFUN supports <fun>=128.

The set command is used to control circuit switched fallback (CSFB) operation. Reporting of CSFB related CS paging requests can be switched on or off. After reporting the command can be used to accept or reject the CSFB call. The command can also be used to control automatic acceptance/rejection of CSFB calls. Refer to clause 9.2 for possible <err> values. CS paging requests are reported with unsolicited result code +CCSFBU in the format: +CCSFBU: <numbertype>,<ton>,<number>[,<ss_code>[,<lcs_indicator>[,<lcs_client_identity>]]] Read command returns the current value of <n>. Test command returns values supported as a compound value.

<n> <numbertype> <ton> <number> <ss_code> <lcs_indicator> <lcs_client_identity>

Optional.

This command returns the coverage enhancement status of the MT. The terminal can consider the coverage enhancement status prior to deciding to transmit data (see e.g. clause 10.1.43). Depending on the coverage enhancement status the terminal can refrain from transmitting data. The coverage enhancement status is only provided by the MT if the access technology (mode) of the serving cell is E-UTRAN (WB-S1 mode), satellite E-UTRAN (WB-S1 mode) or satellite E-UTRAN (WB-S1 mode), EC-GSM-IoT, E-UTRAN (NB-S1 mode), E-UTRAN connected to a 5G CN (NB-N1 mode or WB-N1 mode). If the access technology (mode) of the serving cell is different, <Act>=0 is indicated.The access technology type parameter <Act>, should not be used in terminals capable of only one access technology.

<AcT> <CE_level> <CC>

Optional.

This command allows control of the application level measurement configuration according to TS 25.331 and TS 36.331. The set command controls the presentation of the unsolicited result code +CAPPLEVMC: <app-meas_service_type>,<start-stop_reporting>[,<app-meas_config_file_length>,<app-meas_config-file>] providing data for the configuration. Refer to clause 9.2 for possible <err> values. Read command returns the current value of <n>. Test command returns values supported as a compound value.

<n> <app-meas_service_type> <start-stop_reporting> <app-meas_config_file_length> <app-meas_config-file>

Optional.

This command allows the MT to provide the application level measurement report according to TS 25.331 and TS 36.331. Refer to clause 9.2 for possible <err> values.

<app_meas_service_type> <app-meas_report_length> <app-meas_report>

Optional.
