IMS
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
.
With requirements now defined and user demand increasing, IMS testing
is vital to ensure its successful implementation. 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.
Catapult IMS testing spans 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 offering provides the tools required by network equipment
manufacturers and carriers for:
- Stress Testing Network Elements
- Expandable by adding computing power, 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 allowing free format messaging
and tailored protocol stack testing
- User defined imported C functions
- Intuitive user interface facilitates network administration
for both the test system and IMS nodes including user defined
reporting to assist in analysis
- End to End testing and validation of data traffic
- Interoperability
- Single platform handles multiple interfaces and protocols
to facilitate testing between IMS, WiMAX, UMTS, GPRS, and
PSTN network.
