Execution command returns the MSISDNs related to the subscriber (this information can be stored in the SIM/UICC or in the MT). When storing information in the SIM/UICC, if the currently selected card slot contains a SIM card or a UICC with an active GSM application, the information is stored in the EFMSISDN under DFTelecom. If the currently selected card slot contains a UICC with an active USIM application, the information is stored in the EFMSISDN under ADFUSIM). If subscriber has different MSISDN for different services, each MSISDN is returned on a separate line. Refer to clause 9.2 for possible <err> values.

<alphax> <numberx> <typex> <speed> <service> <itc>

Optional.

Set command controls the presentation of an unsolicited result code +CREG: <stat> when <n>=1 and there is a change in the MT's circuit mode network registration status in GERAN/UTRAN/E-UTRAN, or unsolicited result code +CREG: <stat>[,[<lac>],[<ci>],[<AcT>]] when <n>=2 and there is a change of the network cell in GERAN/UTRAN/E-UTRAN. The parameters <AcT>, <lac> and <ci> are sent only if available. The value <n>=3 further extends the unsolicited result code with [,<cause_type>,<reject_cause>], when available, when the value of <stat> changes. Read command returns the status of result code presentation and an integer <stat> which shows whether the network has currently indicated the registration of the MT. Location information elements <lac>, <ci> and <AcT>, if available, are returned only when <n>=2 and MT is registered in the network. The parameters [,<cause_type>,<reject_cause>], if available, are returned when <n>=3. Refer to clause 9.2 for possible <err> values. The access technology of the serving cell parameter, <AcT>, should not be used in terminals capable of only one access technology. Test command returns values supported as a compound value.

<n> <stat> <lac> <ci> <AcT> <cause_type> <reject_cause>

Optional. This command is not applicable to UEs in NG-RAN or satellite NG-RAN.

Set command forces an attempt to select and register to the GSM/UMTS/EPS/5GS network operator using the SIM/USIM card installed in the currently selected card slot. <mode> is used to select whether the selection is done automatically by the MT or is forced by this command to operator <oper> (it shall be given in format <format>) to a certain access technology, indicated in <AcT>. <regtype> indicates if the registration procedure shall be performed for disaster roaming service (see TS 24.501). If <regtype> is not included then the UE performs a normal registration i.e. a registration not for disaster roaming service (see TS 24.501). If the selected operator is not available, no other operator shall be selected (except <mode>=4). If the selected access technology is not available, then the same operator shall be selected in other access technology. The selected operator name format shall apply to further read commands (+COPS?) also. <mode>=2 forces an attempt to deregister from the network. The selected mode affects to all further network registration (e.g. after <mode>=2, MT shall be unregistered until <mode>=0 or 1 is selected). Refer to clause 9.2 for possible <err> values. This command should be abortable when registration/deregistration attempt is made. Read command returns the current mode, the currently selected operator and the current Access Technology. If no operator is selected, <format>, <oper> and <AcT> are omitted. Test command returns a set of five parameters, each representing an operator present in the network. A set consists of an integer indicating the availability of the operator <stat>, long and short alphanumeric format of the name of the operator, numeric format representation of the operator and access technology. Any of the formats may be unavailable and should then be an empty field. The list of operators shall be in order: home network, networks referenced in SIM or active application in the UICC (GSM or USIM) in the following order: HPLMN selector, User controlled PLMN selector, Operator controlled PLMN selector and PLMN selector (in the SIM or GSM application), and other networks. It is recommended (although optional) that after the operator list TA returns lists of supported <mode>s and <format>s. These lists shall be delimited from the operator list by two commas. The access technology selected parameters, <AcT>, should not be used in terminals capable of only one access technology. Selection of <AcT> does not limit the capability to cell reselections, even though an attempt is made to select an access technology, the phone may still re-select a cell in another access technology.

<mode> <format> <regtype> <oper> <stat> <AcT>

Optional.

Execution command is used to lock, unlock or interrogate a MT or a network facility <fac>. Password is normally needed to do such actions. When querying the status of a network service (<mode>=2) the response line for 'not active' case (<status>=0) should be returned only if service is not active for any <class>. Refer to clause 9.2 for possible <err> values. This command should be abortable when network facilities are set or interrogated. Call barring facilities are based on supplementary services (refer TS 22.088). The interaction of these with other commands based on other supplementary services is described in the specification of the relevant supplementary service. Test command returns facility values supported as a compound value.

<fac> <mode> <status> <passwd> <classx>

The call barring supplementary service control is mandatory for MT supporting AT commands only and not supporting the control through dial command D.

Execution command sets a new password for the facility lock function defined by command Facility Lock +CLCK. Refer to clause 9.2 for possible <err> values. Test command returns a list of pairs which present the available facilities and the maximum length of their password.

<fac>: <oldpwd>, <newpwd> <pwdlength>

Optional.

This command refers to the supplementary service CLIP (Calling Line Identification Presentation) according to TS 22.081 and OIP (Originating Identification Presentation) according to TS 24.607 that enables a called subscriber to get the calling line identity (CLI) of the calling party when receiving a mobile terminated call. Set command enables or disables the presentation of the CLI at the TE. It has no effect on the execution of the supplementary service CLIP / OIP in the network. When <n>=1, the presentation of the calling line identity at the TE is enabled and when the calling subscriber allows, the unsolicited result code +CLIP: <number>,<type>[,<subaddr>,<satype>[,[<alpha>][,<CLI_validity>]]] is returned after every RING (or +CRING: <type>; refer to clause "Cellular result codes +CRC") result code sent from TA to TE. It is manufacturer specific if this response is used when normal voice call is answered. The unsolicited result code +CLIP does not support numbers of the SIP URI format. When <n>=0, the presentation of the calling line identity at the TE with unsolicited result code +CLIP is disabled. The calling line identity 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. Read command gives the status of <n>, and also triggers an interrogation of the provision status of the CLIP supplementary service according to TS 22.081 and OIP supplementary service according to TS 24.607 (given in <m>). Read command returns the current settings. Test command returns values supported as a compound value.

<n> <m> <number> <type> <subaddr> <satype> <alpha> <CLI_validity>

Optional.

This command refers to the supplementary service CLIR (Calling Line Identification Restriction) according to TS 22.081 and OIR (Originating Identification Restriction) according to TS 24.607 that allows a calling subscriber to enable or disable the presentation of the calling line identity (CLI) to the called party when originating a call. Set command overrides the CLIR / OIR subscription (default is restricted or allowed) when temporary mode is provisioned as a default adjustment for all following outgoing calls. This adjustment can be revoked by using the opposite command. If this command is used by a subscriber without provision of CLIR / OIR in permanent mode the network will act according to TS 22.081 and TS 24.607). Read command gives the default adjustment for all outgoing calls (given in <n>), and also triggers an interrogation of the provision status of the CLIR / OIR service (given in <m>). Test command returns values supported as a compound value.

<n> <m>

Optional.

This command refers to the supplementary service COLP (Connected Line Identification Presentation) according to TS 22.081 and TIP (Terminating Identification Presentation) according to TS 24.608 that enables a calling subscriber to get the connected line identity (COL) of the called party after setting up a mobile originated call. The command enables or disables the presentation of the COL at the TE. It has no effect on the execution of the supplementary service COLR / TIR in the network. When <n>=1, the presentation of the connected line identity at the TE enabled and when the called subscriber allows the intermediate result code, +COLP: <number>,<type>[,<subaddr>,<satype> [,<alpha>]] is returned from TA to TE before any +CR or ITU-T Recommendation V.250 [14] responses. It is manufacturer specific if this response is used when normal voice call is established. The intermediate result code +COLP does not support numbers of the SIP URI format. When <n>=0, the presentation of the connected line identity at the TE is disabled. The connected line identity 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. Read command gives the status of <n>, and also triggers an interrogation of the provision status of the COLP supplementary service according TS 22.081 and TIP supplementary service according to TS 24.608 (given in <m>). Test command returns values supported as a compound value.

<n> <m> <number>, <type>, <subaddr>, <satype>, <alpha>

Optional.

This command related to a network service that provides "multiple called numbers (called line identifications) service" to an MT. This command enables a called subscriber to get the called line identification of the called party when receiving a mobile terminated call. Set command enables or disables the presentation of the called line identifications at the TE. When <n>=1, the presentation of the called line identification at the TE is enabled, the unsolicited result code +CDIP: <number>,<type>[,<subaddr>,<satype>] is returned after every RING (or +CRING: <type>; refer to clause "Cellular result codes +CRC") result code sent from TA to TE. It is manufacturer specific if this response is used when normal voice call is answered. The unsolicited result code +CDIP does not support numbers of the SIP URI format. When <n>=0, the presentation of the called line identification at the TE is disabled. The called line identification 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. Read command gives the status of <n>, and also triggers an interrogation of the provision status of the "multiple called numbers" service. Test command returns values supported as a compound value.
