Flowcoder supports all IP based UMTS Signaling Protocols and Interfaces. It includes IuPS (RANAP) interface from NodeB to SGSN, and all protocols/interfaces in the core. All INAP, CAP, H.248, MGCP, RADIUS, and DIAMETER based network interfaces are supported. SIP/RTP is supported.

Every UMTS network interface can be simulated packet-by-packet with both standard and non-standard packets payloads and sequences supported.

Example: Simulating NodeB

IuPS is GTP-U and RANAP based interface. Any packet exchange with SGSN, standard or non-standard can be programmed.

Example: Simulating SGSN

Gn is GTP based interface. Any packet exchange with GGSN, standard or non-standard can be programmed. GGSN side could be simulated as well.

IuPS is GTP-U and RANAP based interface. Any packet exchange with NodeB, standard or non-standard can be programmed. NodeB side can be simulated as well.

Ge is CAP based interface. Any packet exchange with gsmSCF, standard or non-standard can be programmed. gsmSCF side of the interface could be simulated as well.

Gr is MAP based interface. Any packet exchange with HLR, standard or non-standard can be programmed. HLR side of the interface could be simulated as well.
