Direct Tunnel Related Record Extensions
This Information Element (IE) will be added as part of record extension of the CDRs and only one IE added for the Direct

the CDR whenever tunnel mode of PDP context switches from two tunnel to one tunnel.
Tunnel (DT) indication in a CDR. It records the volumes and RNC addresses in DT mode. GGSN includes this field in
the CDR whenever tunnel mode of PDP context switches from two tunnel to one tunnel.
Important:
This is a customer-specific field available in custom6 and custom19 eG-CDRs as part of the Direct
Tunnel feature. This feature can be controlled through the CLI command
gtpp trigger direct-tunnel
. By
default, this field is disabled.
This IE will not be added in the CDRs if PDP context in two tunnel mode since last partial CDR generation.
The new IE for Direct tunnel indication contains following field:
extensionType - Extension type of the IE.
Length - Length of the IE.
saDTuplink - Total volume of uplink data passed over DT mode.
saDTdownlink - Total volume of downlink data passed over DT mode
saRNCaddresslist - List of RNC's address which are formed direct tunnel with GGSN
Example: {{extensionType: 7 Length: 93 {saDTuplink: 0x334 saDTdownlink: 0xf348 saRNCaddresslist {1.1.1.1 2.2.2.2
3.3.3.3 4.4.4.4 5.5.5.5}}
3.3.3.3 4.4.4.4 5.5.5.5}}
