Multiple HNB-GW Service on Single Chassis
In order to associate multiple HNB-GW services with the same CS/PS network and to associate a particular HNB-GW
service with more than one CS/PS network a dynamic association procedure is supported.
service with more than one CS/PS network a dynamic association procedure is supported.
A unique logical RNC represents each CS/PS network on chassis and is assigned an RNC-ID as global RNC id.
When RUA Connect Request is received at HNB-GW, CS/PS network is selected based on values of mcc, mnc and rnc-
id configured in radio network plmn of HNB-GW service and in CS/PS network.

Multiple HNB-GW services in the same context can share the same RTP Pool however a single GTP-U Service cannot
be shared among multiple HNB-GW Services. Similarly, multiple PS networks cannot share a single GTP-U service but
multiple CS networks can share the same RTP Pool and ALCAP Service.

Multiple MSC Selection without Iu-Flex
Support for multiple MSC selection in a CS core network is provided with this feature support.
HNBGW can connect to multiple MSC and SGSN through Iu-Flex or LAC mapping. This feature implements the
multiple MSC selection using LAC.
multiple MSC selection using LAC.
For this support the HNB-GW uses HNB's LAC, received during registration procedure in
HNB_REGISTER_REQUEST message, to distribute RANAP-Initial UE message to an MSC. It maps the LAC with
MSC point code and a set of LACs configured for each MSC, connected to the HNB-GW.
HNB_REGISTER_REQUEST message, to distribute RANAP-Initial UE message to an MSC. It maps the LAC with
MSC point code and a set of LACs configured for each MSC, connected to the HNB-GW.
In the HNBGW, to select an MSC based on the LAC the following algorithm is used:
If both Iu-Flex and LACs are configured for a MSC, then Iu-Flex is used to select a MSC.
If only Iu-Flex is configured then Iu-Flex is used for selecting MSC.
