The subscription of an MS/UE is checked by the PLMN during IP-CAN session establishment procedure as described in 3GPP TS 23.060 [3], 3GPP TS 23.401 [77] and 3GPP TS 23.402 [78]. The GGSN/P-GW implicitly checks its internal context related to the destination address for each mobile terminated packet. For PDN types other than Non-IP, if there is a context IP-CAN session associated with the IP address the packet shall be forwarded towards the MS/UE; otherwise the packet shall be discarded or rejected depending on the implemented protocol. For PDN type "Non-IP", the packet shall be forwarded towards the MS/UE, discarded or rejected depending on the implemented protocol.
