The execution command returns the ATSSS rules <ATSSS_rule-l> and <ATSSS_rule-c> of the QoS flow of the default QoS rule associated to the provided context identifier <cid>. If the parameter <cid> is omitted, the ATSSS parameters for all QoS flows are returned. The test command returns a list of <cid>s associated with all QoS flows.

<cid> <ATSSS_rule-l> <ATSSS_rule-c>

Optional. This AT-cmd is appliccable to UEs that support ATSSS.

The execution command returns the network steering functionalities information <NSFI-l> and <NSFI-c> of the QoS flow of the default QoS rule associated with the provided context identifier <cid>. If the parameter <cid> is omitted, the network steering functionalities information for all QoS flows are returned. The test command returns a list of <cid>s associated with all QoS flows.

<cid> <NSFI-l> <NSFI-c>

Optional.

The execution command is used to activate the specified PDP context(s) or to request for the specified QoS flow. The command is also used to deactivate the context or to delete the QoS flow. The command returns with the response depending upon whether the request is successfully sent to the lower layers or not. The actual result for the PDU session establishment from the network will be displayed through the unsolicited result code +CCSTATEREQU: <result>, <cid> once the indication is received from the network. The request for a specific QoS flow will be answered by the network by a PDU session establishment accept message or a PDU session modification command message. This PDU establishment procedure may require several sessions of request-response of EAP authentication messages between the MT and the network to complete the procedure (see the +C5GPDUAUTHR and +C5GPDUAUTHS commands), see clause 6.3.1 of TS 24.501. For EPS, if an attempt is made to disconnect the last PDN connection, then the MT responds with ERROR or, if extended error responses are enabled, a +CME ERROR. For EPS, the activation request for an EPS bearer resource will be answered by the network by either an EPS dedicated bearer activation or EPS bearer modification request. The request must be accepted by the MT before the PDP context can be set in to established state. If the MT is not PS attached when the request for QoS flow command is executed, the MT first performs a PS attach and then attempts to activate the context or request the specific QoS flow. If no <cid>s are specified, the activation form of the command activates all defined non-emergency contexts. If no <cid>s are specified, the deactivation form of the command deactivates all active contexts. The read command returns the current activation states for all the defined PDP contexts. The state displayed for each context is the previous state until the next state is completely accespted by the MT. The test command is used for requesting information on the supported PDP context activation states.

<cid> <state> <result>

Optional.

The set command controls the presentation of an unsolicited result code +C5GPDUAUTHU: <cid>, <len>, <eap_msg> which will be displayed on receiving an authentication message in the form of Extensible Authentication Protocol (EAP) message from network during or after a UE-requested non-emergency PDU establishment request has been sent. The purpose of the PDU session authentication and authorization is to enable the data network (DN) to authenticate and authorize the upper layers of UE. This procedure happens through EAP as specified in RFC 3748 and clause 6.3.1 of TS 24.501. There can be several sessions of exchange of an EAP-request and EAP-response message for the DN to complete the authentication and authorization of the request for a PDU session. The network shall start a timer (T3590) once the EAP-request message has been sent and expects the EAP-response message from UE to stop the timer. On expiry of the timer, network shall re-transmit the message after restarting the timer. This can be retransmitted for four times. Read command returns the current setting of value <n>. Test command returns the range of supported <n>.

<n> <cid> <len> <eap_msg>

Optional.

Execution command allows the UE to send the EAP-response message to the EAP-request made by network for a particular PDU session. The EAP-request message is received through the unsolicited result code +C5GPDUAUTHU. The authentication request is sent by the network to authenticate and authorize the upper layers of UE when a UE-requested non-emergency PDU session establishment request is sent. The response to the execution command only indicates if the EAP-response message has been successfully sent to lower layers or not.

<cid> <len> <eap_msg>

Optional.

<APPID> <OSID&APPID> <DNNs> <FQDN> <Connection_capabilities> <remote_ipv4_address_and_mask> <remote_ipv6_address_and_prefix_length> <protocol number (ipv4) / next header (ipv6)> <single_remote_port> <remote port range> <security para index> <type of service (tos) (ipv4) and mask/traffic class (ipv6) and mask> <flow label> <ether_type> <destination_mac_address> <cTagVid> <sTagVid> <cTagPcpDei> <sTagPcpDei> <PIN ID> <Connectivity group ID> <Regular_expression> <ursp_rule_type> <ursp_rule_precedence> <route_selection_descriptor_precedence> <SSC_mode> <NSSAI> <pdp_type> <preferred_access_type> <Non-seamless_non-3GPP_offload_indication> <Location_criteria_type> <Time_window_type>

Optional.

This command triggers the MUSIM capable UE to request the network to release the NAS signalling connection for 3GPP access in EPS (see clause 5.5.3.2 and clause 5.6.1 of TS 24.301), or 5GS (see clause 5.5.1 and clause 5.6.1 of TS 24.501) due to activity on another USIM. When the TE sends this command to MT, the MT immediately returns OK and triggers the release of the NAS signalling connection. Refer to clause 9.2 for possible <err> values.

Optional.

The set command controls the presentation of unsolicited result code +CREJPAG: <paging_cause> when <n>=1 reporting the paging cause indication for which the MUSIM capable UE has received a page. The following cases are applicable in EPS (see clause 5.5.1 of TS 24.301) and 5GS (see clause 5.5.1 of TS 24.501).

1. UE receives page from a network that does not support paging cause indication for voice services; or
2. UE receives page from a network that supports paging cause indication for voice services and page is not related to voice service; or
3. UE receives page from a network that supports paging cause indication for voice services and page is related to voice service.

When <n>=2, a special form of the set command +CREJPAG: <rejpage_pgcause_unknown>,<rejpage_pgcause_not_voice>,<rejpage_pgcause_voice> enables the MUSIM capable UE to reject the paging request from the network in EPS (see clause 5.6.1 of TS 24.301), and 5GS (see clause 5.6.1 of TS 24.501). The TE sends this command (when <n>=2) to the MT in anticipation of MT receiving indication of paging from the network. The read command returns the current settings of <n> and indicates whether currently the paging request received from the network is set to be rejected or not for the different cases described above. Refer to clause 9.2 for possible <err> values. The test command returns values of supported <n>s.

<n> <paging_cause> <rejpage_pgcause_unknown> <rejpage_pgcause_not_voice> <rejpage_pgcause_voice>

Optional.

The set command controls the presentation of unsolicited result code +CPAGRES: <paging_restrict_result> when <n>=1 reporting that the paging restriction preferences specified by the MUSIM capable UE have been accepted by the network or not. When <n>=2, a special form of the set command enables the MUSIM capable UE to specify the paging restriction preferences to the network for 3GPP access in EPS (see clause 5.5.3.2 and clause 5.6.1 of TS 24.301) and 5GS (see clause 5.5.1 and clause 5.6.1 of TS 24.501). The paging restriction preferences can be set or removed. Refer to clause 9.2 for possible <err> values. The read command returns the current settings of <n> and paging restrictions. The test command returns values supported as a compound value.

<n> <paging_restrict_result> <paging_restrictions> <number_of_restricted_cid> <cid>

Optional.

The set command controls the presentation of unsolicited result code +CPAGTCC: <mobile_identity>[,<IMSI_offset>] when <n>=1 reporting the mobile identity of the UE and the negotiated alternative IMSI value offset that have been specified by the network for a MUSIM capable UE that supports paging timing collision control. When <n>=2, a special form of the set command enables the MUSIM capable UE to specify the requested alternative IMSI offset value to the network for 3GPP access in EPS (see clause 5.5.1.2 and clause 5.5.3.2 of TS 24.301). When the TE sends this command to MT, the MT immediately returns OK. Refer to clause 9.2 for possible <err> values. The read command returns the current settings of <n>, <mobile_identity> and <IMSI_offset>. The test command returns values supported as a compound value.

<n> <mobile_identity> <IMSI_offset>

Optional.
