IMS Testing Systems
With requirements now defined and user demand increasing, IMS testing
is vital to ensure its successful implementation.
The IP Multimedia Subsystem (IMS) is a 3GPP industry reference architecture
that defines the common control and interoperability between existing
wireline, wireless and emerging IP-based communications networks.
IMS standards define an all-IP-based wireless network built upon
recognized IETF protocol specifications.
Given the complexity that IMS brings to the network, there are new
challenges. There is a need to fully stress network components while
verifying their proper interworking.
For the IMS Network, the Catapult IMS test systems will perform:
- Network Simulation
- Network Validation
- Gateway Testing
- Node Validation
Catapult IMS test systems span the various network layers including
application, service control and transport. Within these layers
are several systems associated with the IMS architecture including:
- Call Session Control Functions (CSCF)
- Inter-working Elements (i.e. Media Gateways)
- Subscriber Services
- Databases (i.e. HSS)
Catapult IMS test systems provide the tools required by network
equipment manufacturers and service providers for:
Stress Testing Network Elements:
- Expandable: add computing power or physical interfaces to any
of the Catapult family of scalable platforms
- Traffic generation simulating thousands of subscribers for
signaling and user plane testing
- Flexible load testing for an array of traffic patterns
Functional testing:
- Full protocol stack testing including transport and security
layers
- Unparalleled flexibility for free format messaging and tailored
protocol stack testing
- Flexible design development lets users import their own pre-developed
test suites
- Intuitive user interface facilitates network administration
for both the test system and IMS nodes
- Network testing and validation of data traffic
Interworking:
- A single platform handles multiple interfaces and protocols
to facilitate testing between IMS, WiMAX, UMTS, GPRS and PSTN
