Configuration Parameters

To configure each mobile network node type, you need the parameters below:

Parameter name Description Applies to Values or example Notes
PC Type Type of the SS7 Point Codes Entire network ITU, ANSI
NI Network Indicator Entire network national, reserverdnational, international
PC SS7 Point Code Each SS7 node 1035, 1-107-5
GT SCCP Global Title MSC, VLR, SGSN, HLR 882500010 May be shared by all components running on a SS7 node
MGT Type Type of GT used for IMSI addressing Entire network E.212, E.214
CC Country Code prefix Usually entire network 882 VPLMN components located abroad should have local CC
Node number Identity in a cluster VLR, SGSN 1 to 10 bits integer Can be same for VLR and SGSN if a 1:1 relationship exists
Node bits Bits for identity VLR, SGSN, YateBTS 1 to 10 Can be same for VLR and SGSN if a 1:1 relationship exists
IGWMSC Outbound calls gateway MSC Protocol specific Typically the GMSC is also IGWMSC
Roaming No Pool of Roaming Numbers VLR 882990020-882990049 The pool can be shared with handover numbers
Handover No Pool of Handover Numbers MSC 882990050-882990059 The pool can be shared with roaming numbers
SGSN GTP-C GSN IP Address SGSN IP Address Alternative (or only) IPv6 address may be present
SGSN GTP-U GSN IP Address SGSN IP Address May be same or different from the GTP-U Address
