Understanding the Service Operation

The system provides wireless carriers with a flexible solution for providing Mobility Management Entity (MME)
functionality for LTE networks.
The system functioning as a MME is capable of supporting the following types of subscriber data sessions:
UE-initiated: The subscriber is provided basic access to a packet data network (PDN) without the MME
authenticating the subscriber. Either a static or dynamic IP address can be assigned to the MS in this scenario.
Network-initiated: An IP Packet Data Unit (PDP) is received by the MME from the PDN for a specific
subscriber. If configured to support network-initiated sessions, the MME, will initiate the process of paging the
UE and establishing a EPS bearer context.
Prior to connecting to the command line interface (CLI) and beginning the system's configuration, there are important
things to understand about how the system supports these applications. This chapter provides terminology and
background information that must be considered before attempting to configure the system.
