- <cid>: numeric; specifies a particular PDP context definition.
- <PDP_type>: string; specifies the type of packet data protocol
X.25 : ITU-T/CCITT X.25 layer 3 (Obsolete)
IP : Internet Protocol
IPV6 : Internet Protocol, version 6
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)
- <APN>: string; a logical name that is used to select the GGSN or the external packet data network
- <PDP_addr> for EPS, this field is omitted.
- <d_comp>: numeric; controls PDP data compression.
0 - off (default if value is omitted)
1 - on (manufacturer preferred compression)
2 - V.42bis
3 - V.44
Other values are reserved.
- <h_comp>: numeric; controls PDP header compression.
0 - off (default if value is omitted)
1 – on (manufacturer preferred compression)
2 - RFC1144 (applicable for SNDCP only)
3 - RFC2507
4 - RFC3095 (applicable for PDCP only)
Other values are reserved.
- <IPv4AddrAlloc>: numeric; controls how the MT/TA requests to get the IPv4 address information
0 - IPv4 Address Allocation through NAS Signaling (default if omitted)
1 - IPv4 Address Allocated through DHCP
- <emergency indication>: a numeric parameter used to indicate whether the PDP context is for emergency bearer
services or not.
0 PDP context is not for emergency bearer services
- <P-CSCF_discovery>: a numeric parameter influences how the MT/TA requests to get the P-CSCF address, see
3GPP TS 24.229 [89] annex B and annex L.
0 Preference of P-CSCF address discovery not influenced by +CGDCONT
1 Preference of P-CSCF address discovery through NAS Signalling
