Section: 23.3.2.3.3 Security Gateway
Content: The Security Gateway (SeGW) FQDN shall be derived as follows. The "segw" <system> label is added in front of the operator's OAM realm domain name: segw.oam.mnc<MNC>.mcc<MCC>.3gppnetwork.org If particular operator deployment scenarios where there are multiple Security Gateways (one per vendor), the <vendor ID> label is added in front of the "segw" label: vendor<ViD>.segw.oam.mnc<MNC>.mcc<MCC>.3gppnetwork.org An example of a SeGW FQDN is: MCC = 123; MNC = 45; ViD = abcd; which gives the SeGW FQDN: "segw.oam.mnc045.mcc123.3gppnetwork.org" and "vendorabcd.segw.mnc045.mcc123.3gppnetwork.org".
