Parameter Type Description
<cid> Number See <cid>
<PDP_type> String See <PDP_type>
<APN> String See <APN>
<PDP_addr> Number See <PDP_addr>
<d_comp> Number PDP data compression; it can have the values:
• 0 (default value): off
• 1: on (predefined compression type i.e. V.42bis data compression)
• 2: V.42bis data compression
• 3: V.44
<h_comp> Number PDP header compression; it can have the values:
• 0 (default value): off
• 1: on (predefined compression type, i.e. RFC1144)
• 2: RFC1144
• 3: RFC2507
• 4: RFC3095
<h_comp>: the available head-compressions are dependent on configuration of
the stack (configured via features in the stack)
<IPv4AddrAlloc> Number Controls how the MT/TA requests to get the IPv4 address information:
• 0 (default value): IPv4 Address Allocation through NAS Signalling
• 1: IPv4 Address Allocated through DHCP
<emergency_
indication>
Number Indicates whether the PDP context is for emergency bearer services or not:
• 0 (default value): PDP context is not for emergency bearer services
• 1: PDP context is for emergency bearer services
<request_type> Number Indicates the type of PDP context activation request for the PDP context:
• 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 (default value): PDP context is for new PDP context establishment
