2-level structure including nation-wide backbone network and provincial network.
Provincial networks are interconnected through the nation-wide backbone.
Two types of nation-wide backbone nodes: backbone node and core node. In principle, core nodes are connected fully-meshed, in order to save links,they are partly connected fully-meshed recently.

Structure of CMNet
Backbone nodes are connected through core nodes.When necessary, the connection between two backbone nodes are permitted.
Two types of provincial nodes: aggregation node and common node.
Aggregation nodes are used to connect common nodes to the nation-wide backbone. In principle, Aggregation nodes are connected fully-meshed, in order to save links, we use partly full-mesh connections recently.

Structure of CMNet
Aggregation nodes are connected to the nation-wide backbone nodes directly.
In principle, common nodes are connected to the nation-wide backbone through aggregation nodes. When necessary, the direct connection between common nodes and backbone/core nodes are permitted.

How CMCC will construct its GPRS network?
Two level structure: GPRS provincial network:provide GPRS
carried service to end users GPRS nation-wide backbone:Interconnect all
the GPRS provincial networks to realize inter-province roaming; interconnected with other PLMN to realize inter-PLMN roaming.

usage of IP address
Use CMNet as IP backbone of GPRS network
GPRS node use public IP addressUsage of user address :
Dynamically allocated public IP address Dynamically allocated private IP address and use
NAT when access Internet Statically allocated private IP address and use N
AT when access Internet
