Understanding the Service Operation
CS network configured at the system level need to be associated with a Radio Network PLMN configured
within HNB-GW service with desired granularity; PLMN level or location-area in that PLMN.
PS Network: PS Network is a context independent configuration to define packet switched networks . This
packet switched network configuration provides parameters for one or more SGSN where PS-domain Iu-
connections shall be routed. In a typical deployment HNB-GW is connected to only one SGSN.
PS network configured at the system level need to be associated with a Radio Network PLMN configured
within HNB-GW service with desired granularity.
GTP-U services: GTP-U services are configured in Context configuration mode in pair of two servics; one for
GTP-U tunnel support towards HNB on Iuh interface and another for GTP-U tunnel support towards the core
network on IuPS interface to communicate with SGSN respectively.
The system supports multiple GTP-U interface connections over this service. Although this service can be
configured in any independed context, but for Iuh interface it must be configured in the same context as HNB-
GW; i.e. source context.
Following figure illustrates the relationship between services, interfaces, and contexts within the HNB-GW system for
HNB access 3G UMTS networks.
