Goal

According to the network deployment policy, 3GPP system use the policy to deploy the corresponding network.

Actors and Roles

NM create/delete/update/query/activate/deactivate the network deployment policy, EM execute the NM’s policy operation request, and notifies NM policy conflict, if exist.

Telecom resources

3GPP management system (EM, NM)

Assumptions

3GPP management system want to deploy a network

Pre conditions

The operator designs the network deployment requirement and need deploy the network based on the requirement.

Begins when

There is a new network policy about the network deployment.

Step 1 (M)

The operator sets up the network deployment policy through NM.

Step 2 (M)

The NM activates the policy and notifies related EM.

Step 3 (M)

The EM follows the policy to design the network then the network is instantiated by the management system.

Ends when

The EM informs the NM that the policy has been executed.

Exceptions

One of the steps identified above fails.

Post Conditions

The network is correctly configured and normally running
