Conclusion


Two types of multivendor testing

Generic Interoperability Testing (IOT)• Generic testing of standard open telecom interfaces between network

elements from two suppliers (bilateral)• Focus on features with direct impact on procedures and transactions

over the interface• Integration parameters are defined by the two suppliers• Results of generic IOT sessions are made available for all customers

with the relevant configuration

Local Multivendor Integration (MVI)• Integration and verification of exact customer specific configuration• Interworking testing and verification of functionalities, applications

and services used in customer network• Integration parameters according to the customer transmission and

network planning• Local MVI is performed in the customer test bed or in the field as a

joint project between the customer and the vendors


Nokia Networks IOT & MVI mission

• Nokia Networks supports openness and sees it as an advantage to the operators and industry as a whole

• Nokia Networks provides 3rd party network and terminal interoperability service to secure customer’s network investment, service deployment and end-user satisfaction

• By bilateral generic interface level interoperability testing (IOT) sessionsand

• By customer specific multivendor integration (MVI) sessions

• Nokia IOT activity is concentrated into three locations worldwide• Espoo Finland, Dallas USA, and Beijing China

• MVI service provided in any customer testbed or field test network• Nokia Networks is able to provide full scale MVI service according to

customer needs• A dedicated project done by joint effort between customer, Nokia and

other vendors• MVI service, process, resources and support available now

Nokia Networks Multivendor Capability Overview

• 3GPP Rel’99 network and terminal IOT is progressing as business as usual following the principles used in GSM and GPRS since early 1990’s

• Since the start of 3G IOT in 2001 several rounds of tests has been carried out over all the main telecom interfaces, first using pre-commercial and since late 2002 commercial SW releases

• The main interfaces and functionalities tested include e.g.

• Um, Uu, A, Gb, Iu-CS, Iu-PS, Iur, C/D, E/G, Gr/Gs, Gn/Gp, Nb/Nc

• AMR, PS data, CS data, Multi-RAB (AMR + 1 PS); SHO for all previous bearers; 3G ↔ 2G cell reselection; ISHO 3G ↔ 2G for AMR; CCO 3G → 2G for PS and Multi-RAB; 2G → 3G ISHO for Multi-RAB (AMR + PS suspended i.e. 3G → 2G ISHO performed first and then going back to 3G); PS CCS – Cell_DCH ↔ Cell_FACH ↔ Cell_PCH; Security (authentication, integrity protection, ciphering); IFHO for AMR, PS, CS data and Multi-RAB; SRNS Relocation for AMR, PS, CS data and Multi-RAB

• Over 200 network and terminal IOT and test sessions run during 2004 alone!

• More than 40 3G multivendor integrations have been successfully completed confirming the results gained in laboratory also in operators’ network environment

CUSTOMER CONFIDENTIALCopyright Nokia & Alcatel, November 2004.

UMTS Interoperability testing between Nokia & Alcatel Achievements & Plans (November 2004)

• In 2002, Alcatel and Nokia have completed a major milestone with successful 3G Voice Calls performed during the Inter Operability Tests (IOT) campaigns of the Iu-CS interface. These tests were run first on releases compliant to 3GPP R99 baseline.

• These successfully completed Iu-CS IOT sessions apply to both Alcatel's RAN configuration with Nokia’s Core Network and Nokia’s RAN configuration with Alcatel's Core Network. D and Gr IOT sessions (MSC/SGSN to HLR interfaces) have been run on reciprocal configurations too.

• Nokia and Alcatel have focused in 2003 and 2004 on 3G/2G IOT. A first session on inter-system voice handovers was successfully run in April 2003 between Nokia RAN / 3G NSS and Alcatel BSS / 2G NSS, which has been completed in 4Q2003 with the equivalent session on packet data side. Alcatel RAN / Nokia BSS reciprocical IOT test sessions have also been conducted successfully during 1Q2004.

• During 2004, Nokia and Alcatel have performed several Iu and 3G2G IOT sessions using latest available SW releases. Iu-PS IOT (Alcatel's RAN with Nokia’s Packet Core Network), with data calls up to 384 kbit/s, has been tested in 2Q2004. SRNS relocation IOT has been successfully performed between RAN and CN nodes from both vendors.

• Further IOT sessions are planned during 1H2005, including an Iu session between Nokia’s 3GPP Rel’04 RAN and Alcatel’s CN in 1Q2005. Reciprocal Iu session, and Iur session are forecasted for mid-2005 between Nokia and Alcatel 3GPP Rel’04 RNCs.

• Interoperability testing is a way of securing interworking of equipment from different vendors. Nokia and Alcatel apply the interoperability testing methodology defined by the NVIOT Forum, keeping in mind joint customer projects.

UMTS Interoperability testing between Nokia & Nortel Networks: Achievements & Plans (November 2004)

• During 2002 and 1H2003, Nortel Networks and Nokia have performed several IOT sessions related to the Iu-CS and Iu-PS interfaces (Interfaces between the Core Network and the Radio Access Network RAN) compliant to 3GPP Rel’99 standard.

• End-to-end voice calls, including SMS, have been achieved, but also end-to-end Data calls, up to 384 kbit/s were successfully tested (Nokia RAN with Nortel CN and Nokia CN with Nortel RAN). Also Gr IOT have been conducted during July 2002 between PS-CN and HLRs (subscribers databases) of both providers.

• During 1H2003, Nokia and Nortel have focused on 3G/2G IOT sessions, and have successfully verified GSM/UMTS intersystem handovers and cell reselections in a multivendor environment. These results have been obtained with both Nortel RAN / Nokia BSS and Nokia RAN / Nortel BSS configurations.

• With additional features included in latest RAN releases, both companies have conducted new Iu IOT sessions during 2H2003. Also IOT between Nokia MSS (3GPP Rel’04) and Nortel 3G/2G (3GPP Rel’99) network elements have been succesfully performed between 4Q2003 and 1Q2004.

• Nokia and Nortel have focused during 2Q2004 on Iur and SRNS relocation IOT tests. New Iu IOT sessions have been conducted in 3Q2004 with Nortel RAN4.0, as well as Gn IOT between Nokia SGSN2.1 and Nortel GGSN4.0. Nokia 3GPP Rel’04 RAN with Nortel Core Network IOT configuration is currently being tested.

• Further IOT sessions are planned for 1H2005, including several Iu, Iur and 3G2G IOT sessions using latest available SW releases.

CUSTOMER CONFIDENTIALNokia – Siemens IOT Project status overview 08.12.2004 / Nokia: Janos Arrakoski, Siemens: Markus Zimmermann page: 1

Nokia-Siemens IOT Project Status• Nokia and Siemens have continued interoperability tests for WCDMA

network infrastructure compliant to 3GPP R4. Tested interfaces include Iu and Iur interfaces. The tests cover functionality with an impact on the interface including handovers (3G/3G and 2G/3G). Testing has been carried out using Nokia RAN connected to Siemens MSC (Iu-cs), Nokia SGSN connected to Siemens RAN (Iu-ps), and Nokia RAN connected to Siemens RAN (Iur).

• The GSM and GPRS IOT program continues normally with several completed tests on A and Gb interfaces using Nokia BSS connected to Siemens MSC and SGSN, as well as Siemens BSS connected to Nokia MSC and SGSN respectively. Verification of Gr and Gs interfaces has also been performed for Nokia SGSN and Siemens HLR and MSC.

• EDGE IOT has been completed using Nokia BSS and Siemens SGSN, and will be continued using Siemens BSS and Nokia SGSN

• Further interoperability testing will be carried out following the industry-wide process and principles of interoperability testing according to both vendors new software release availability and market requirements.
