Introduction to IPGb Function
IPGb refers to a type of networking, which uses the IP transmission network on the Gb interface as an intermediate network to connect iBSC and SGSN.
For IP transmission on the Gb interface, we can use the point-to-point dedicated network (intranet) or a publish IP transmission network (internet).

Configuration Type
The NSVC configuration methods of IPGb falls into two types: static configuration and dynamic configuration.
Static configuration is applied when the point-to-point dedicated network is used. As FR Gb, IP Gb requires a consistent static configuration between iBSC and SGSN.
Dynamic configuration(or static configuration) is applied when the public network connection is used on the Gb interface. In this case, the NS sub-layer provides a set of SNS dynamic flow for the dynamic configuration.
SGSNiBSCSIZE/CONFIGUE/ADD/DELETE/iBSCSGSNiBSCSGSN
When the dynamic configuration is used, SGSN and iBSC negotiate and generate the configuration data at the peer end through SIZE/CONFIGUE/ADD/DELETE flows. The negotiation process follows the Client/Server configuration model; iBSC is the Client, and SGSN is the Server. Therefore, the iBSC should be configured with at least one static port of SGSN, so that the two ends can start the data negotiation flow.

iBSC first starts the SIZE flow, through which it informs SGSN of the max number of NSVCs and the max number of IP ports that BSS supports. When the SIZE flow is completed, iBSC starts the CONFIG flow, and then SGSN starts the CONFIG flow. The end mark of the CONFIG flow is the end mark in the SNS_CONFIG message. The normal service flows cannot start until the CONFIG flows started by both iBSC and SGSN are completed.

Configuring NSE (2)
NSE ID: It must be the same as that at SGSN side;
Sub-network type: Choose “IP” for IP Gb;
Configuration type: static configuration & dynamic configuration;
Static configuration is used for the point-to-point dedicated network; it requires manual configuration for parameter consistency.
Pre-configured SGSN IP address: It is the IP address of SGSN; it must be configured, if the dynamic configuration type is adopted;
Pre-configured SGSN UDP port No.: It is the UDP port No. of SGSN; it must be configured, if the dynamic configuration type is adopted;
