1、LTE MME Emulator 4An MME implementation designed for lab use and for testing UE, eNodeB, MME, Serving GW and Inter-RAT handovers with SGSN 4Implements all the required protocols - S1AP and SCTP to communicate with eNodeBs, eGTP-C (GTPv2-C) to communicate with S- GWs, SGSNs and MMEs, and DIAMETER to
2、communicate with HSS. The LTE MME Emulator is a part of the family of LTE Network Equipment Emulators from Polaris Networks. The LTE Network Equipment Emulators together allow testing in a variety of network topologies, allowing the user to utilize lab equipment effectively and reduce capital expend
3、iture and ongoing support costs associated with a test lab. The MME Emulator provides a lower-cost solution and greater control as compared to a real MME for testing the functionality, scalability and performance of LTE User Equipment and Network Equipment, including MME, S-GW and eNodeB. The MME Em
4、ulator includes all the network interfaces and implements all the communication protocols required for an MME to operate in an LTE/SAE network. In addition, the MME Emulator provides a scripting interface (using the TCL programming language) to configure and control its functions and obtain performa
5、nce statistics and test results. The MME Emulator also supports the ability to emulate multiple MME devices for the purpose of scalability testing. APPLICATIONS LTE User Equipment and Network Equipment Manufacturers can use the MME Emulator as a low-cost alternative to a real MME during the product
6、development and system quality assurance phases. The MME Emulator can be used to: LTE Test Tool vendors can integrate the MME Emulator in their LTE test system to enhance the capabilities of their test system. The MME Emulator can be integrated as a binary object using a TCL or C programming interfa
7、ce. Alternatively, the MME Emulator source code is available for tighter integration. MME manufacturers can license the protocol stack software in the MME Emulator to accelerate their product development and reduce the time to market. FEATURES The MME Emulator includes The S1AP and SCTP protocols re
8、quired to communicate with an eNodeB. It can communicate with multiple eNodeBs and it can emulate multiple MMEs at the same time for testing Handover scenarios. The eGTP-c (GTPv2-c) protocol required to communicate with a S-GW. The eGTP-c (GTPv2-c) protocol required to communicate with an SGSN. The
