1 Spectra2 for IMS Testing Validation of IMS architectural elements is key for building scalable application platform necessary for new revenue opportunities.. IMS OVERVIEW Emerging technologies provide opportunities for Manufacturers and Operators to leverage their existing solutions to create new valueadded services. With an open service infrastructure, an IP Multimedia Subsystem (IMS) offers real-time multimedia services for both fixed and mobile network users. As it supports multiple access modes, IMS has become the core network's standard architecture in the All-IP era. After developing and maturing over the last several years, IMS today has crossed the chasm to become the mainstream choice for VoBB and PSTN network migration in the fixed-call field. The main drivers behind IMS today are: VoLTE (Voice over LTE): IMS is identified as the standard architecture for mobile voice service by 3GPP and GSMA as it is the only architecture that can provide a voice solution with the QoS assurance based on LTE. Business/Consumer VoIP: As operators and cable MSOs look to provide value added Enterprise Business VoIP services, IMS Core serves as a platform of choice for providing desired QoS as well as rolling out faster services. SUPPORTED TEST DOMAINS Spectra2 is powered by advanced signaling and media generation capabilities that enable high performance testing of protocols like SIP, Diameter, Megaco, ISUP, TCAP and RTP. This broad coverage of protocols helps you test and tune following network nodes in IMS Core: Call Server Control Function (CSCF) Home Subscriber Server (HSS) Diameter Routing Agent (DRA) Policy Charging Rules Function (PCRF) IMS Application Servers (IMS-AS) Media Gateway Control Function (MGCF) Media Gateway (MGW) Media Resource Function Controller (MRFC) Media Resource Function Processor (MRFP) Application Services: New application services architectures like Rich Communication Services (RCS) and Web Real Time Communication (WebRTC) services, involve various signalling and media types that are well designed and served in an IMS Core environment.

2 IMS Network Architecture The IMS network architecture includes four main network components: IMS Core, Application Servers, Inter-workings with multiple networks, and Access Networks. IMS Core P-CSCF (Proxy-Call Session Control Function): a SIP proxy represents UE to the other servers. I-CSCF (Interrogating-Call Session Control Function): the contact point for IMS connections destined to a subscriber, switches calls based on routing information. S-CSCF (Serving-Call Session Control Function): provides session control services, maintains the session stage, and registration for the users. SLF (Subscription Locator Function): provides the name of the HSS based on inquiries from I-CSCF, AS, and 3GPP AAA. HSS (Home Subscriber Server): a database containing the user information, including user ID/numbering/addressing, profile, location, and security. Policy Management Nodes PCRF (Policy Charging and Rules Function): This element receives session and media-related information from the Application Function, such as the P-CSCF and controls policy decisions regarding the service data flow detection, gating, Quality of Service (QoS), and flow-based charging. This element is looked at as a bandwidth/resource optimization function as well a key node for new revenue generation. OCS (Online Charging System): This element provides real-time charging capability based on user initiated events and sessions. It controls user sessions and services based on the available credits. Some OCS implementations also work closely with the PCRF in the policy decision making process. OFCS (Offline Charging System): This element collects charging information for network resource usage which is then passed on to billing systems in the format of a CDR. This element does not control user service/session usage in real-time as they are rendered. Application Servers Offers value-added IMS services (such as gaming, messaging, etc SIP AS (SIP Application Server) OSA AS (Open Service Access Application Server) CAMEL IM-SSF (CAMEL - IP Multimedia-Service Switching Function) Interworking with the CS Network IMS works with CS networks to enable the connection between IMS and PSTN/ISDN, or between IMS and Mobile CS network. MGCF (Media Gateway Control Function): controls Media Gateway and converts PSTN signalling to/from SIP signalling. MGW (Media Gateway): supports media conversion, bearer control and payload processing. BGCF (Breakout Gateway Control Function): addresses CS users for IMS TE originated calls. Interworking with the IP Network IBCF (Interconnection Border Control Function): performs interconnection between two operator domains. It is also responsible for topology hiding; controlling transport plane functions; screening of SIP signalling information; selecting the signalling interconnect; generation of charging data records. TrGW (Transition Gateway): located within the media path and controlled by an IBCF, providing network a dress/port translation and IPv4/IPv6 protocol translation. Interworking with the Multimedia IP Network MRFC (Media Resource Function Controller): interprets information coming from an AS and S- CSCF, controls media stream resources in the MRFP, and generates CDRs. MRFP (Media Resource Function Processor): controls bearers, provides resources, mixes/ sources/processes incoming streams, and manages floor control for conferencing. Access Network Wireless Networks including: 4G LTE, 3G UMTS/WCDMA, cdma2000, TD-SCDMA, EDGE, GPRS, WiFi/Wireless LAN Fixed Networks including: PSTN, ISDN, Consumer VoIP (SIP and H.323), Cable, and xdsl Business VoIP: VoIP communication services including voice, video, presence and mobility services that connect enterprise communications with operator IMS Core.

3 IMS Testing Challenges IMS brings both benefits and challenges to NEMs and operators. Different standard bodies each with unique requirements and specifications; Flexible IMS specifications and endless extensions; Access independence requires interworking; Architecture independence causes proprietary standards and interoperability challenges; User independence requires advanced authentication, authorization and security; Service independence requires open API (Application Programming Interface) with the consideration of today s and future services. Types of Testing To face the above IMS challenges, NEMs need to verify and validate the products under development. IMS service operators need to test and monitor deployed networks. Feature and Functional Testing - Does each network component functionally work? Load and Stress Testing - Can the network unit or system tolerate the heavy signalling and media traffic? Conformance Testing - Does the network comply with standards or proprietary specifications? Interoperability Testing - Is the network made up of equipment from multiple vendors or operators? QoS Measurement - Does the media quality meet the Service Level Agreement? Monitoring - Where is the bottleneck? Spectra2 for IMS Testing Page 3 of 10

4 Spectra2 for IMS Testing Integrated IMS Solution Tektronix Spectra2 meets above requirements.

Support Tektronix provides customer support throughout the product life cycle - design, development and deployment. Advanced Functional Testing Model Simulations: Spectra2 s Advanced Signalling and Media Generator (ASMG) can support up to 10 inter-working call legs in a single test scenario. It can support up to 100 scenarios in a single test model empowering users to script complex diameter signalling interactions that make up the functionality of several nodes in the Diameter network. Broad Protocol Coverage: Spectra2 supports signalling and media protocols in IMS, EPC and PSTN domains making it ideal for testing multi-domain scenarios. SIP Auto-scripting provides the ability to create test scripts from a wireshark packet capture, preserving the message timing, sequence and contents to reflect the production environment. SIP InjectRAW empowers users to work with captured media traffic by creating media action based on RTP traffic from pcap import, preserving media/rtp packetization anomalies. SIP User Agent (UA) Profiles support offers improved user simulation. Spectra2 users can gain more control and customization over database profile attributes assigned to end-users. The Spectra2 API (Application Programming Interface) lets users run tests and save the results of those tests from a remote system. The Spectra2 API further automates the lab testing function and leverages the solution s value by providing a platform-independent method for remotely accessing Spectra2 from a Windows or UNIXbased system. Conditional Branching support enables users to handle conditional scripting options such as If/Then/Else functionality. Conditional Branching is included in all Spectra2 protocol testing packages for both functional and load testing. Multi-Protocol Call Trace (MPCT) threads together one session containing multiple protocols based on the correlation rules. Multi-gateway Support for Megaco and MGCP Spectra2 can emulate a large number of very small Media Gateways. This allows Spectra2 to support load testing of Media Gateway Controllers responsible for customer-premise equipment such as Multimedia Terminal Adapters, Integrated Access Devices or residential gateways.

5 Pre-built IMS PDU Library: Spectra2 has a pre-built PDU library for IMS and other technologies. Positive and Negative Testing: Spectra2 supports both normal cases such as IMS SIP Registration and SIP Invite, and abnormal cases such as SIP Bad Event and SIP Busy Here are supported, as well as the capability to create flawed messages. Load and Stress Testing Once the DUT is determined, Spectra2 can generate heavy signalling and media traffic to verify DUT capacity limits, as well as the DUT s ability to withstand high traffic. Flexible call patterns and traffic models with various traffic combinations: Signalling only, Signalling + Authentication, Signalling + Security, Signalling + Media (Audio&/ Video), Signalling + Media + QoS. Multiple Generator Models: Spectra2 supports simultaneous generation of multiple traffic models from a single user license and interface board. This performance enhancing feature enables concurrent execution of test cases thereby reducing overall test time and increasing product time to market Traffic profiles can be customized based upon the users load profile/requirements, including BHCA, Calls Per Second, Erlang, Simultaneous Call, Call Hold Time, Package Size, Package Rate and Interpackage Delay. Conformance Testing Spectra2 s approach to IMS testing starts with standards based conformance testing to ensure IMS protocol compliance to the specifications. Spectra2 provides more than 450 SIP test cases as defined by the ETSI TIPHON specification TS Each test case can easily be edited to adapt to your testing requirements. Spectra2 also support Conformance Test Suites for various Diameter interfaces. (Details in Compliance Matrix) Interoperability Testing IMS interoperability testing involves the interworking between: Multiple standard body protocols with their unique variants, as well as manufacturer-defined proprietary specifications. Different network architectures planned and deployed by different carriers. Spectra2 supports multiple standard body protocols implementations and proprietary specifications. Along with the ability to customize PDUs to meet any specialized testing need. Quality of Service Measurement QoS measurements are critical for IMS service. Key QoS parameters, such as Network Delay, Jitter (Variation in Delay) and Packet Loss, need to be measured to ensure the quality of the audio, video, and multimedia services. Spectra2 supports following QoS mechanisms: Passive QoS: Passive QoS provides analysis and scoring of RTP stream integrity using MOS, PESQ, and R-Factor based scores. Active QoS: Active QoS provides a PESQ or MOS QoS score based on a comparison of transmitted and received audio payload. Spectra2 measures QoS for both audio and video media, as well as voice path verification. Audio: MOS (Mean Opinion Score), PESQ, R- Factor, Jitter Video: MOS-V (Mean Opinion Score - Video), VSTQ, RT Delay Spectra2 Video QoS mechanism looks to GOP structure to assess the impact of a lost packet on video quality. Monitoring Spectra2 supports IMS network monitoring, generates statistical reports, and provides multiprotocol analysis tools such as call trace, message filtering, and message decode. Apply filters based on source and destination IP Addresses, protocol type, or user-defined ASCII or hex string. Optional media support enables RTP stream analysis and playback. Monitored PDUs can be saved and used in test cases and generator models. Analysis can be performed in real time or post capture. The captured data can be exported to open formats such as CSV and text for further analysis with third-party tools. Network Address Translation and Security for IPv4 networks and IPv6 networks.
