IxCatapult

Future-proofing Mobile Networks

IxCatapult validates the ability of mobile network infrastructures to accommodate fast-rising data volumes and related spikes in signaling traffic. Users can conduct protocol conformance, functional, and load/stress testing to ensure the performance and scalability of the network control plane of both core and radio access network (RAN) devices.

Increasing signaling traffic impacts user authentication and authorization, mobility, charging, policy management, and QoS. The failure of elements such as subscriber databases and mobility management entities (MMEs) can in turn cause costly service interruptions.

IxCatapult emulates control plane signaling on a city scale to validate performance and capacity. Simulating virtually any network node—and multiple nodes simultaneously—the solution represents properly functioning and misbehaving devices to preempt issues and validate deployments in the lab.

Industry-leading IxCatapult capabilities include:

  • RNC Testing: Ixia’s RNC Test solution measures Radio Network Controller (RNC) performance to prevent issues from arising under load and in complex mobility scenarios. Testing features complete functional and performance testing of UTRAN network components and HSPA+ capabilities. Delivering the industry’s highest signaling load test capacity, Ixia emulates multiple network entities to reduce test requirements.
  • SS7 Testing: Ixia’s Message Generator and Traffic Simulator™ (MGTS) evaluates SS7 over Legacy and SIGTRAN technology used to interconnect telecom networks in increasingly IP-based networks. MGTS validates the functionality and performance of signaling and media gateways, emulating SS7/PSTN entities and SS7 application databases to reduce test costs and development time.
  • Femtocell testing: IxCatapult tests femtocell access points and gateways used to extend indoor cellular coverage. Testing addresses integration challenges inherent in integrating femtocells into existing networks. In the absence of mature standards, IxCatapult equips users to develop test scripts for successful implementations.

Equipment vendors and service providers worldwide use IxCatapult during product development, QA testing, and network buildout. Using a unique protocol-centric model, the solution precisely measures the real-world behavior of mobile infrastructure devices as well as overall network performance.
