The Landslide VoLTE/IMS Node and SIP UE Emulation feature adds Session Initiation Protocol (SIP)-based Voice over LTE (VoLTE) client emulation capabilities to LTE Mobility Management Entity (MME) and LTE Gateway Test Applications. In addition, it adds a standalone SIP proxy/IMS P-CSCF node for testing scenarios that do not require emulated UE SIP clients. Landslide’s VoLTE/IMS emulation feature allows the creation of test scenarios with thousands of user equipment (UEs) placing and receiving VoLTE calls while simultaneously sending and receiving data.
Complex call modeling scenarios can be created that include UEs in various stages of activation, deactivation, handovers, data transfers, and VoLTE calling. Landslide can test against the entire Evolved Packet Core (EPC), or it can emulate most network elements based on testbed requirements. The Landslide VoLTE implementation follows GSMA IR.92, and GSMA IR.94, and is the tool of choice for testing interoperable VoLTE network and equipment implementations.
Features and Benefits
- Realistic, real-world simulations that allow equipment vendors to accurately specify the performance characteristics of their equipment under real-world conditions
- Simultaneous control and user plane that allow service providers to measure the performance of their network and to validate new features and services in the lab
- Test any ePC network element in isolation or in an end-to-end configuration using realistic data while UEs place and receive VoLTE calls
- Easily test ePC network element performance, scalability, and VoLTE call handling capability while the effects of dynamic PCC are investigated
- Use Landslide’s data message flows, traffic mixer, and emulated SIP clients to determine the impact of real-world traffic profiles on VoLTE Quality of Experience (QoE)
- Unmatched scalability allows the user to simulate subscriber loads ranging from a small rural town to the largest metropolitan city
- Emulate multiple network elements to test a variety of network topologies
- Emulate key network elements to reduce capital expenditure and ongoing support costs
- Create real-world scenarios for heavy load, BHCA modeling, and long duration stability tests
- Test any ePC network element in isolation or end-to-end configuration with realistic UEs
