+CGCONTRDP: (list of <cid>s associated with active contexts)

NOTE: The syntax of the AT Set Command is corrected to be according to ITU‑T Recommendation V.250 [14]. Older versions of the specification specify incorrect syntax +CGCONTRDP=[<cid>]

Description

The execution command returns the relevant information <bearer_id>, <apn>, <local_addr and subnet_mask>, <gw_addr>, <DNS_prim_addr>, <DNS_sec_addr>, <P-CSCF_prim_addr>, <P-CSCF_sec_addr>, <IM_CN_Signalling_Flag>, <LIPA_indication>, <IPv4_MTU>, <WLAN_Offload>, <Non-IP_MTU>, <Serving_PLMN_rate_control_value>, <Reliable_Data_Service>, <PS_Data_Off_Support>, <PDU_session_id>, <QFI>, <SSC_mode>, <S-NSSAI>, <Access_type>, <RQ_timer>, <Always-on_ind>, <Ethernet_MTU>, <Unstructured_Link_MTU>, < PDP_type>, <EDC_policy_ind> and <ECSConf_info_ind>for an active non secondary PDP context or a QoS flow of the default QoS rule with the context identifier <cid>.

If the MT indicates more than two IP addresses of P-CSCF servers or more than two IP addresses of DNS servers, multiple lines of information per <cid> will be returned.

If the MT has dual stack capabilities, at least one pair of lines with information is returned per <cid>. First one line with the IPv4 parameters followed by one line with the IPv6 parameters. If this MT with dual stack capabilities indicates more than two IP addresses of P-CSCF servers or more than two IP addresses of DNS servers, multiple of such pairs of lines are returned.

NOTE: If the MT doesn’t have all the IP addresses to be included in a line, e.g. in case the UE received four IP addresses of DNS servers and two IP addresses of P-CSCF servers, the parameter value representing an IP address that can not be populated is set to an empty string or an absent string.

If the parameter <cid> is omitted, the relevant information for all active non secondary PDP contexts is returned.

The test command returns a list of <cid>s associated with active non secondary contexts.
