The set command controls the setting of the UEs eDRX parameters. The command controls whether the UE wants to apply eDRX or not, as well as the requested eDRX value for each specified type of access technology. The set command also controls the presentation of an unsolicited result code +CEDRXP: <AcT-type>[,<Requested_eDRX_value>[,<NW-provided_eDRX_value>[,<Paging_time_window>]]] when <n>=2 and there is a change in the eDRX parameters provided by the network. A special form of the command can be given as +CEDRXS=3. In this form, eDRX will be disabled and data for all parameters in the command +CEDRXS will be removed or, if available, set to the manufacturer specific default values. Refer to clause 9.2 for possible <err> values. The read command returns the current settings for each defined value of <AcT-type>. The access technology type parameter <AcT-type>, should not be used in terminals capable of only one access technology. The test command returns the supported <mode>s and the value ranges for the access technology and the requested eDRX value as compound values.

<mode> <AcT-type> <Requested_eDRX_value> <NW-provided_eDRX_value> <Paging_time_window>

Optional.

The execution command returns <AcT-type> and <Requested_eDRX_value>, <NW-provided_eDRX_value> and <Paging_time_window> if eDRX is used for the cell that the MS is currently registered to. If the cell that the MS is currently registered to is not using eDRX, AcT-type=0 is returned.

<AcT-type> <Requested_eDRX_value> <NW-provided_eDRX_value> <Paging_time_window>

Optional.

The set command controls which CIoT optimizations the UE indicates as supported and preferred in EPS and in 5GS. A UE supporting CIoT functionality may support,

• control plane CIoT EPS optimization or user plane CIoT EPS optimization or both (see clause 9.9.3.34 of TS 24.301) when the UE is connected to EPC; or
• control plane CIoT 5GS optimization or user plane CIoT 5GS optimization or both (see clause 5.3.21 of TS 24.501) when the UE is connected to 5GCN.

Based on the application characteristics the UE may prefer to be registered for,

• control plane CIoT EPS optimization or for user plane CIoT EPS optimization (see clause 9.9.3.0B of TS 24.301) when the UE is connected to EPC; or
• control plane CIoT 5GS optimization or for user plane CIoT 5GS optimization (see clause 5.3.21 of TS 24.501) when the UE is connected to 5GCN.

Further,

• in EPS the network can support control plane CIoT EPS optimization or user plane CIoT EPS optimization or both (see clause 9.9.3.12A of TS 24.301); and
• in 5GS the network can support control plane CIoT 5GS optimization or user plane CIoT 5GS optimization or both (see clause 5.3.21 of TS 24.501)

The set command is also used to control the reporting of the CIoT optimizations by the unsolicited result code +CCIOTOPTI. The unsolicited result code +CCIOTOPTI: <supported_Network_opt> is used to indicate the CIoT optimizations supported by the network in EPS and in 5GS. Refer to clause 9.2 for possible <err> values. The read command returns the current settings for supported and preferred CIoT optimizations in EPS, the current settings for supported and preferred CIoT optimizations in 5GS and the current status of unsolicited result code +CCIOTOPTI. The test command returns values supported as compound values.

<n> <supported_UE_opt>

<preferred_UE_opt> <supported_Network_opt>

Optional.

Set command forces an attempt to select and register to the CSG Cell in UMTS/EPS network. <mode> is used to determine whether the selection is done automatically by the MT or is forced by this command to select CSG Cell in CSGinfo <CSGinfo> (it shall be given in format <format>) to a certain access technology, indicated in <AcT>. If the selected access technology is not available, then the same CSG id and associated PLMN shall be selected in other access technology. If the selected CSG cell is not available in all supported RATs, then MT shall follow the procedures described in clause 4.4.3.1.3 of TS 23.122. The selected CSG info format shall apply to further read commands (+CCSGS?) also. <mode>=0 forces an attempt to register to the CSG cell in UMTS/EPS network. <mode>=1 forces an attempt to do manual CSG selection to a CSG cell as per information in CGSinfo <CSGinfo>.<mode>. This command is used when the ME performs successfully registered to a PLMN i.e. the UE executed Operator Selection (+COPS) command successfully. Read command returns the current CSG selection mode, the currently selected CSG Cell information <CSGinfo> and the current Access Technology. If ME is not camped on CSG Cell when read command is issued, +CME ERROR: XX (Not camped on CSG Cell) shall be issued. Test command returns a set of four parameters. A set consists of an integer indicating the availability of the CSG in Operator CSG list or Allowed CSG list <stat>, alphanumeric format of the CSG Type, HNB name, CSG ID and Associated PLMN MCC MNC<CSGinfo>, numeric format representation of the CSG ID and Asssociated PLMN MCC MNC <CSGinfo> and access technology <AcT>. <CSGinfo> consist of CSGType (if available from SIM), HNB name, CSG ID each delimited by comma. CSG Type shall provide the type of a CSG identity in a human readable form. See TS 22.011, TS 23.003 for details of CSG Type, HNB name and CSG ID representation. Any of the formats may be unavailable and should then be an empty field. The list of found CSG's shall be in order: CSG's in the Operator CSG list, CSG's in the Allowed CSG list, other CSG's. It is recommended (although optional) that after the CSG list TA returns lists of supported <mode>s and <format>s. These lists shall be delimited from the CSG list by two commas. The access technology selected parameters, <AcT>, should only be used in terminals capable to support CSG selection in more than one access technology. Selection of <AcT> does not limit the capability to cell reselections, even though an attempt is made to select a CSG id in an access technology, the phone may still select the same CSG id and associated PLMN in another access technology.

<mode> <format> <CSGinfo> <stat> <AcT>

Optional. This command is only applicable to UEs in UTRAN and E-UTRAN.

Set command triggers the MT to select and register on a CAG cell. <mode> is used to determine whether the selection is done automatically by the MT or is done in manual selection mode on the CAG cell identified by <CAGinfo> (which shall be given in format <format>) to a certain access technology, indicated in <AcT>. If the selected CAG cell is not available, then the MT shall follow the procedures described in clause 4.4.3.1.2 of TS 23.122. The selected CAG info format shall apply to further read commands (+CCAGS?) also. <mode>=0 forces an attempt to register to the CAG cell in NR/5GS network. <mode>=1 forces an attempt to do manual CAG selection to a CAG cell as per information in CAGinfo <CAGinfo> This command is used when the ME has successfully registered to a PLMN i.e. the UE executed Operator Selection (+COPS) command successfully. Read command returns the current CAG selection mode, the currently selected CAG cell information <CAGinfo> and the current Access Technology. If the ME is not camped on a CAG cell when read command is issued, +CME ERROR: XX (Not camped on CAG cell) shall be issued. Test command returns a set of four parameters. A set consists of an integer indicating whether the CAG-ID is present in the "Allowed CAG list" <stat>, HRNN, CAG ID and Associated PLMN MCC MNC<CAGinfo>, numeric format representation of the CAG ID and Associated PLMN MCC MNC <CAGinfo> and access technology <AcT>. <CAGinfo> consist of HRNN, CAG ID, Associated PLMN MCC MNC and an indication of whether the MT is only allowed to access the Associated PLMN in 5GS via CAG cells, each delimited by a comma. See TS 23.003 for details of HRNN and CAG ID representation. Any of the formats may be unavailable and should then be an empty field. It is recommended (although optional) that after the CAG list TA returns lists of supported <mode>s and <format>s. These lists shall be delimited from the CAG list by two commas.

<mode> <format> <CAGinfo> <stat> <AcT>

Optional. This command is only applicable to UEs in NG-RAN.

The set command controls the presentation of an unsolicited result code +CCKEYREQ: <result>[,<no_of_ciph_key_data_set>] when <n>=1 and there is a response received from the network for a request to provide new ciphering keys in the registration procedure. The purpose of requesting the ciphering keys is to obtain the list of ciphering data sets from the network that can be used by the UE for deciphering of ciphered broadcast data. The request to obtain th ciphering keys is made through the parameter which will be sent to the network in the registration procedure. Read command returns the currentset values. Test command values supported as a compoung value.

<n> <ciph_req> <result> <no_of_ciph_key_data_set>

Optional. This command is only applicable to UEs supporting 5GS.
