Product Development & Testing Services for IuPS and IuCS Interfaces
Overview
Universal Terrestrial Radio Access Network (UTRAN) is a group term for network and equipment that connects mobile to the public telephone network/Internet. It contains the base stations (Node B’s) and Radio Network Controllers (RNCs) and this communications network, commonly referred to as 3G can carry many traffic types from real-time Circuit Switched to IP based Packet Switched. The UTRAN also allows connectivity between the UE and the core network.
In UMTS, the interface between RAN and CN is the Iu. For uniformity, 3GPP specifies a single protocol at Radio Network Layer for the Iu-CS and Iu-PS interfaces both i.e., RANAP for the control plane and Iu for the user plane.
The Radio Access Network Application Protocol (RANAP) is the Radio Network Layer protocol for the Iu interface. The peer entities of RANAP reside in 3G MSC/SGSN and the SRNC. All the RANAP functions are elaborated in 3GPP TS 25.413. The Control Plane includes the application protocols and the signaling bearers which transport the control information.
The application protocols used at different UTRAN interfaces are:
- Iu-CS: Radio access network application protocol (RANAP)
- Iu-PS: Radio access network application protocol (RANAP)
- Iub: Node B application protocol (NBAP)
- Iur: Radio network system application protocol (RNSAP)
IuPS interface works between the UMTS RNC (Radio Network Controller) and the SGSN (Serving GPRS Support Node) supporting UMTS integrated services such as multimedia and global roaming to mobile users. IuCS interface in UMTS links the RNC (Radio Network Controller) with a 3G MSC (3G Mobile Switching Centre).

OdiTek’s Offerings
OdiTek has competencies to verify IuPS Interface using various leading proprietary Simulator tools. We can test simulation of the RNC and 3G SGSN by generating Radio Access Network Application Part (RANAP) signaling messages over SCTP as Transport layer in an IP network as defined by 3GPP standards (3GPP TS 25.410). Iu-CS is the interface specified between the RAN and the 3G MSC.
Similarly we can test IuCS interface emulating the RNC (Radio Network Controller) and the MSC (Mobile Switching Centre) by generating RANAP and DTAP signaling messages over SCTP. It includes ready scripts to simulate Location Update, Call Control MO (Mobile Originating), Mobile Terminating (MT), Mobile-to-mobile Voice Call/ SMS, SMS over active voice call, and Handover (Relocation) procedures etc.
Load Testing
We can perform load / capacity testing to measure and monitor stability of the test solution including efficiency of IuCS and IuPS interfaces towards the RNC/HNB Gateway.
Primary measurements in load can be:
- Realistic network simulation of 1,000 RNCs and massive 10,000,00 number of UEs
- Simulating to find the behavior of all involved parties in-order to verify whether the SUT (SGSN or GGSN) is capable to manage 3G mobile subscribers in moving state
Conclusion
At OdiTek, we have excellent knowledge across various Telecom entities, Telecom products etc. We will be happy to assist you and plan your testing activities. Please drop us an email on info@oditeksolutions.com.
