IPV4V6 Virtual <PDP_type> introduced to handle dual IP stack UE capability
OSPIH Internet Hosted Octect Stream Protocol (Obsolete)
PPP Point to Point Protocol (IETF STD 51 [104])
Only IP, IPV6 and IPV4V6 values are supported for EPS services.
<APN> String type; a logical name that is used to select the GGSN or the external packet data
network. If the value is null or omitted, then the subscription value will be requested. The
APN is a string of up to 82 characters.
<PDP_addr> String type; identifies the MT in the address space applicable to the PDP. This parameter
can be left blank.
When +CGPIAF is supported, its settings can influence the format of this parameter
returned with the read form of +CGDCONT.
The value of this parameter is ignored with the set command. The parameter is included in
the set command for backwards compatibility reasons only.
<d_comp> Integer type; controls PDP data compression
0 Off
1 On (manufacturer preferred compression)
2 V.42bis
3 V.44
<h_comp> Integer type; controls PDP header compression
0 Off
1 On (manufacturer preferred compression)
2 RFC 1144 [105] (applicable for SNDCP only)
3 RFC 2507 [107]
4 RFC 3095 [108] (applicable for PDCP only)
<IPv4AddrAlloc> Integer type; controls how the MT/TA requests to get the IPv4 address information
0 IPv4 address allocation through NAS signalling
1 IPv4 address allocated through DHCP
<request_type> Integer type; indicates the type of PDP context activation request for the PDP
context. Please refer to 3GPP TS 24.301 (subclause 6.5.1.2) and 3GPP TS
24.008 (subclause 10.5.6.17). If the initial PDP context is supported it is not
allowed to assign <cid>=0 for emergency bearer services. According to 3GPP TS
24.008 (subclause 4.2.4.2.2 and subclause 4.2.5.1.4) and 3GPP TS 24.301
(subclause 5.2.2.3.3 and subclause 5.2.3.2.2), a separate PDP context must be
established for emergency bearer services.
If the PDP context for emergency bearer services is the only activated context,
only emergency calls are allowed, refer to 3GPP TS 23.401 subclause 4.3.12.9.
0 PDP context is for new PDP context establishment or for handover from
a non-3GPP access network (how the MT decides whether the PDP
context is for new PDP context establishment or for handover is
implementation specific).
1 PDP context is for emergency bearer services
2 PDP context is for new PDP context establishment
3 PDP context is for handover from a non-3GPP access network
<P-CSCF_discovery>Integer type; influences how the MT/TA requests to get the P-CSCF address, refer
