Usage
This command enables the SGSN to support dual PDP-type addressing (IPv4v6) per RNC.
For a dual PDP context to be activated, the RNC should support the PDP-type IPv4v6 in the RAB assignment
request. For an RNC that does support the dual PDP-type addressing, use this command to change the default
configuration and to configure the SGSN to work with the RNC's dual address bearer support capability.
If the RNC does not support this functionality, then the

form of this command should be configured
to enable the SGSN to activate a single-address bearer PDP context even if (1) the UE requests PDP type
IPv4v6 and if (2) the subscription allows this PDP type. The single address bearer PDP type will be activated
with a configured PDP type.
When a UE moves from an RNC that supports dual PDP-type addressing to another RNC that does not
support dual PDP-type addressing, then the SGSN will deactivate the PDP context. This is done because,
even if we preserve the PDP contexts, the UE would be unaware of the preserved PDP context. This would
lead to non-synchronized behavior in the network. So the SGSN deactivates the PDP context with cause code
