PDP Activation failed Possible Root Cause 3GPP 29.060 7.7.1

"No resources available" indicates that not enough resources are available within the network to
allow the PDP Context to be created.
"Missing or unknown APN" indicates e.g. when the GGSN does not support the Access Point
Name.
"Unknown PDP address or PDP type" indicates when the GGSN does not support the PDP type
or the PDP address.
"User authentication failed" indicates that the external packet network has rejected the service
requested by the user e.g. the authentication check in the RADIUS server failed.
"PDP context without TFT already activated" indicates that a PDP context has already been
activated without a TFT for that MS.
"Context not found" indicates that a Create PDP Request for a subsequent PDP context has been
received, but the PDP context associated with the request, which the SGSN believes to be active
does not exist on the GGSN.
"APN access denied – no subscription" indicates that the GGSN has denied the user access to an
APN because a subscription is required, but the subscriber does not have the necessary
subscription.
"New PDP type due to network preference" indicates that the GGSN has selected a PDP type
different from the one sent by the MS.
"New PDP type due to single address bearer only" indicates that the MS has requested PDP type
IPv4v6 and both IPv4 and IPv6 addressing is possible in the PDN but the Dual Address Bearer
Flag bit of the Common Flags IE is set to 0 or the Common Flags IE is absent, or only single IP
version addressing is possible in the PDN.
