About MME Testing


The Mobility Management Entity (MME) is the key control-node for the LTE access-network. It is responsible for Idle mode UE tracking and paging procedure including re-transmissions. It is involved in the bearer activation/deactivation process and is also responsible for choosing the Security Gateway (SGW) for a UE at the initial attach . MME is also responsible for authenticating the user (by interacting with the HSS.

The Non-Access Stratum (NAS) signaling terminates at the MME and it is also responsible for generation and allocation of temporary identities to UEs. The MME is the termination point in the network for ciphering/integrity protection for NAS signaling and handles the security key management.

SGW Emulation

When emulating an SGW in a MME Nodal test case, Landslide supports the following functionality:

eNodeB Emulation

The eNodeBs are connected by means of the S1-MME interface to the MME and to the Serving Gateway (S-GW) by means of the S1-U. The S1 interface supports a many-to-many relation between MMEs/Serving Gateways and eNodeBs. When emulating eNodeB in a MME Nodal test case, Landslide supports the following functionality:
