LTE - IMS Network Test Solutions

Overview

GL's LTE Analyzer is capable of capturing, decoding and performing various test measurements across various interfaces over LTE and IMS networks. GL's Message Automation and Protocol Simulation Platform (MAPS™) - a multi-protocol and multi-interface simulation software can be used to simulate almost all elements in the wireless 2G, 3G, and 4G networks. One can also setup a virtual real-time network simulating all the network elements using ‘MAPS™ 2G 3G 4G Wireless Lab Suite'.  MAPS™ LTE Emulator supports emulation of several interfaces in LTE and IMS network: S1 - MME, X2-AP, eGTP-c (S3, S4, S5, S8, S10, S11 and S16), and Diameter (S6a, S6d, S13, Cx, Dx, Gx, and Rx). It can simulate up to 500 Smart phones (UEs) powering up and down.
 
4G LTE Communications Network Lab
 
End-to-End Voice, Video, and Data Quality Test Suite
 
 
 
 
GL offers an End-to-End 4G LTE-IMS Communications Network Lab (CNL) with all components such as eNodeB, MME, Serving Gateway, PDN Gateway, HSS, PCSCF, ICSCF,PCRF, PCEF, AF and others to simulate both E-UTRAN and EPC (Evolved Packet Core), allowing complete testing of the LTE network.

All functionalities conform to industry standards. The CNL provides reliable integrated solutions to vendors and service providers for simulation, monitoring, troubleshooting the 2G, 3G and 4G mobile networks.
GL’s VQuad™ LTE solution is network independent QoS test solution; all Voice and Data networks are supported including 4G LTE, Advanced LTE, 3G, WiMax, and the upcoming 5G. 

GL’s VQuad™ NetTest solution provides automated data testing - includes TCP, UDP, HTTP, FTP, DNS, VoIP, SMS, and Email tests. GL’s Video Application Part (VAC) supports Video Conference testing.  GL’s Voice Quality Testing (VQT) supports automated voice quality between using - POLQA (ITU-P.863) and PESQ (ITU-P.862). The POLQA algorithm is specifically used for testing Wideband VoLTE networks.

 
LTE eGTP Interfaces Emulation
(S3, S4, S5, S8, S10, S11 and S16)
GL's MAPS™ designed for testing LTE S11, S5/S8 (eGTP) interfaces can simulate Mobility Management Entity (MME), Serving Gateway (SGW), and Packet Data Network Gateway (PGW) network elements. The MAPS™ LTE eGTP gives the users the unlimited ability to edit S11, S5/S8 eGTP-C messages and call scenarios (message sequences).

MAPS™ LTE Emulator supports Real-time traffic over GTP can be emulated using the Mobile Traffic Simulation (ETH101, and ETH102) modules. It also supports powerful utilities like Message Editor, Script Editor, and Profile Editor which allow new scenarios to be created or existing scenarios to be modified using message templates and profiles. "Message sequences" are generated through scripts. "Messages" are created using message templates.
 
LTE X2 AP Interface Emulation

The X2 Application Protocol (AP) is the interconnecting interface between two eNodeBs in LTE network and supports both Control Plane and User Plane. The principle Control Plane protocol is X2 Application Protocol (X2-AP) resides on Stream Control Transmission Protocol (SCTP).

GL's MAPS™ LTE X2AP is used to co-ordinate handovers and performs load management between Evolved Node B (eNodeB) network elements - Source eNodeB and Target eNodeB. The MAPS™ X2-AP test tool is designed with specific test cases, as per LTE 3GPP mobile standards.

 
LTE S1 Interface Emulation

LTE is an all IP infrastructure with service priority built in – audio and video are given priority. All necessities like IP address, authentication, and security are validated. Instant resources over RF (the air) and IP (internal network) are made available depending on what the user is attempting to do. Also, LTE is designed for compatibility with older 2G and 3G mobile systems.

GL's MAPS™ designed for testing LTE - S1 interface can simulate Evolved Node B (eNodeB), and Mobility Management Entity (MME). The application gives the users the unlimited ability to edit S1-AP/NAS messages and call scenarios (message sequences).

 
IMS Interfaces Emulation

Within LTE, MAPS™ Diameter can simulate S6a, S6d, S13, Cx/Dx, Gx, Rx, and Sh interfaces and test network elements such as the MME, Home Subscriber Server (HSS), Application Function (AF), Policy and Charging Rules Function (PCRF), Call Session Control Function(CSCF), Serving GPRS Support Node (SGSN), Policy and Charging Enforcement Function (PCEF), Equipment Identity Register (EIR), Packet Data Network Gateway (PDN GW), and Application Server (AS).

GL’s MAPS™ SIP IMS test suite provides an advanced full-fledged network environment that enables user to simulate multiple UEs and IMS core elements such as P-CSCF, I-CSCF, S-CSCF, PCRF, MGCF which provides the IMS core network. With the help of real mobile phones, and other simulated elements, the VoLTE Lab setup can be operated in real-time for making VoLTE calls and also for interworking with PSTN and VoIP networks.
 
 
LTE– IMS Protocol Analysis

LTE -IMS Analyzer has unlimited capturing, decoding, and measurement capability and it also supports variety of protocol stack for decoding S1, S3, S4, S5 (or S8), S6a, S10, S11, S13 and X2 interfaces and Diameter sessions over S6a, S6d, Cx, Dx, Sh, Gx, and Rx interfaces.

GL's PacketScan™ - an All-IP Network Monitoring software offers powerful features to capture and monitor live signaling and traffic over IP (version 4 and 6). The application can capture, segregate, monitor and collect statistics all types of calls over LTE-IMS network. Almost all VoIP and Wireless protocols and traffic types over IP network, can be captured and decoded for troubleshooting network problems.
 
Centralized Web-based
LTE Monitoring System
GL's NetSurveyorWeb™ is based on a scalable and flexible architecture. It is used in conjunction with GL's LTE-IMS Protocol Analyzer probes to non-intrusively monitor the entire network from remote testing locations.

GL's LTE-IMS protocol analysis probes feed data to centralized database (Oracle) in real-time for further analysis. The probes provide instant visibility into the performance with extensive KPIs, and also the operation of nodes in LTE networks.
