7.3.1 Iurh-Interface Control Plane Protocol Stack

25.4673GPPRelease 17Stage 2TSUTRAN architecture for 3G Home Node B (HNB)

The figures below show the control plane protocol stack for Iurh both for direct connectivity between HNBs and for connectivity between a HNB and a macro RNC via the HNB-GW.

Figure 7.3.1-1 shows the control plane protocol stack for the direct Iurh-connectivity option between HNBs.

NOTE: The option that Iurh signalling traffic may be routed on IP level via the HNB-GW is depicted by the optional protocol entity boxes within the routing function.
