Set command enables or disables the indication for WLAN offloading based on the thresholds for cell measurement parameters. If reporting is enabled by <n>=1, the MT returns the following unsolicited result code from MT to TE whenever the cell measurement parameters meet the criteria for WLAN offloading based on configured thresholds: +CWLANOLCMI: <rscp>,<ecno>,<rsrp>,<rsrq> If a setting is not supported by the MT, +CME ERROR: <err> is returned. Refer to clause 9.2 for possible <err> values. Read command returns the current status of result code presentation and the measurements from the current primary serving cell at the MT. Test command returns the values supported by MT as compound values.

<n> <rscp> <ecno> <rsrp> <rsrq>

Optional.

Set command controls the presentation of unsolicited result code +CABTSRI: <apn>,<event_type>[,<residual_backoff_time>,<NSLPI>[,<procedure>]] reporting the APN back-off timer parameter values from MT to TE if the back-off timer is started, stopped, deactivated or expires. Refer to clause 9.2 for possible <err> values. Read command returns the current APN back-off timer unsolicited result code settings in the MT. Test command returns values supported as a compound value.

<n> <apn> <event_type> <residual_backoff_time> <NSLPI> <procedure>

Optional.

The execution command returns the relevant information in the MT for the APN back-off timer parameter values <residual_backoff_time>, <NSLPI> and <procedure> for an <apn> if the back-off timer is running. If the parameter <apn> is omitted, the relevant information for all APNs associated with running session management back-off timers is returned.

<apn> <residual_backoff_time> <NSLPI> <procedure>

Optional.

The execution command is used by the TE to transmit data over control plane to network via MT. Context identifier <cid> is used to link the data to particular context. This command optionally indicates that the application on the MT expects that the exchange of data:

• will be completed with this uplink data transfer; or
• will be completed with the next received downlink data.

This command also optionally indicates whether or not the data to be transmitted is an exception data. If the UE is using Reliable Data Service to transmit data, then this command optionally also indicates the source port number used by the originator, the destination port number to be used by the receiver and whether the originator is soliciting an acknowledgement from the receiver as defined in TS 24.250. This command causes transmission of an ESM DATA TRANSPORT message, as defined in TS 24.301. Refer to clause 9.2 for possible <err> values. Test command returns range of supported <cid>s, the maximum number of bytes of user data indicated by <cpdata_length>, supported <RAI>s, supported <type_of_user_data>s, supported <sourcePort>s, supported <destinationPort>s and supported <ackRequest>s as compound values. Defined values

<cid> <cpdata_length> <cpdata> <RAI> <type_of_user_data> <sourcePort> <destinationPort> <ackRequest>

Optional.

The set command is used to enable and disable reporting of data from the network to the MT that is transmitted via the control plane in downlink direction. If <reporting>=1, the MT returns the unsolicited result code +CRTDCP: <cid>,<cpdata_length>,<cpdata> when data is received from the network. If <reporting>=2, the MT returns the unsolicited result code +CRTDCP: <cid>,<cpdata_length>,<cpdata>,<sourcePort>,<destinationPort> when data is received from the network using the Reliable Data Service as defined in TS 24.250. Refer to clause 9.2 for possible <err> values. Read command returns the current settings. Test command returns supported values as compound values.

<reporting> <cid> <cpdata_length> <cpdata> <sourcePort> <destinationPort>

Optional.

This execution command returns the APN rate control parameters (see TS 24.008) associated to the provided context identifier <cid>. If the parameter <cid> is omitted, the APN rate control parameters for all active PDP contexts are returned. The test command returns a list of <cid>s associated with secondary and non secondary active PDP contexts.

<cid> <Additional_exception_reports> <Uplink_time_unit> <Maximum_uplink_rate>

Optional.

The set command enables the UE to specify the PS data off UE status to the network during UE-requested PDP context activation and UE-requested PDP context modification procedure (see clause 4.7.1.10 of TS 24.008 and clauses 6.1.3.1 and 6.1.3.3), during attach, UE-requested PDN connectivity, and UE-requested bearer modification procedure (see clause 6.3.10 of TS 24.301, and clauses 5.5.1, 6.5.1, and 6.5.4), and during UE-requested PDU session establishment, and UE-requested PDU session modification procedure (see clause 6.2.10 of TS 24.501, and clauses 6.4.1 and 6.4.2). The PS data off UE status may be activated or deactivated. Refer to clause 9.2 for possible <err> values. The read command returns the current settings for PS data off UE status. The test command returns values supported as a compound value.

<PS_Data_Off_Status>

Optional.

The set command controls the presentation of an unsolicited result code +C5GREG: <stat> when <n>=1 and there is a change in the MT's network registration status in 5GS, or unsolicited result code +C5GREG: <stat>[,[<tac>],[<ci>],[<AcT>],[<Allowed_NSSAI_length>],[<Allowed_NSSAI>]] when <n>=2 and there is a change of the network cell in 5GS or the network provided an Allowed NSSAI for 3GPP access. The parameters <AcT>, <tac>, <ci>, <Allowed_NSSAI_length> and <Allowed_NSSAI> are provided 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. The value <n>=4 extends the unsolicited result code with [,<cag_stat>] when the value of <cag_stat> changes. The value <n>=5 extends the unsolicited result code with [,<caginfo>] when UE camps on a CAG cell. <caginfo> is displayed only when <cag_stat> is 1. Refer to clause 9.2 for possible <err> values. The 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 <tac>, <ci> and <AcT>, and parameters <Allowed_NSSAI_length>, <Allowed_NSSAI>, 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. Test command returns values supported as a compound value. The parameter [,<cag_stat>], if available, is returned when <n>=4. The parameter [,<caginfo>], if available, is returned when <n>=5.

<n> <stat> <tac> <ci> <Allowed_NSSAI_length> <Allowed_NSSAI> <AcT> <cause_type> <reject_cause> <cag_stat> <CAGinfo>

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

This command indicates to the MT the frequency bandwidth preference for uplink or for downlink. For BL UEs or for UEs operating in coverage enhancement mode. If further conditions defined in TS 36.331 are met, this may cause transmission to the network of a UEAssistanceInformation message with bw-Preference set to <uplink_bandwidth_preference> and <downlink_bandwidth_preference>. Test command returns the values supported as compound values. Refer to clause 9.2 for possible <err> values.

<uplink_bandwidth_preference> <downlink_bandwidth_preference>

Optional.

The set command allows the TE to specify the 5GS Quality of Service parameters <cid>, <5QI>, [<DL_GFBR> and <UL_GFBR>] and [<DL_MFBR> and <UL_MFBR>] for a QoS flow (see TS 23.501 and TS 24.501). Refer to clause 9.2 for possible <err> values. A special form of the set command, +C5GQOS= <cid> causes the values for context number <cid> to become undefined. The read command returns the current settings for each defined QoS. The test command returns the ranges of the supported parameters as compound values.

<cid> <5QI> <DL_GFBR> <UL_GFBR> <DL_MFBR> <UL_MFBR>

Optional.
