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
