Field Description
Paging Request Specifies to enable the CN to send a paging message to a particular UE. 
The procedure without response is connectionless. When the UE is idle, 
paging is performed through a common paging channel; when the UE has 
already had a Radio Resource Control (RRC) connection, paging is 
performed via its dedicated RRC connection.
Relocation Request Once resource allocation for relocating the target RNC fails, the target RNC 
sends a RELOCATION FAILURE message to the CN. Upon receipt of the 
message by the CN, the CN sends a RELOCATION PREP FAILURE 
message to the source RNC. The Iu connection for relocating the target RNC 
is released. The call continues to be held at the source side.
Reset Procedure RANAP EPs are classified into: connection-oriented and connectionless.

IU PS Associations Commands
The following IU PS associations commands can be launched from the logical inventory by 
right-clicking a SGSN service and choosing Commands > Configuration. Your permissions determine 
whether you can run these commands (see Permissions Required to Perform Tasks Using the 
Prime Network Clients). To find out if a device supports these commands, see the Cisco Prime Network

Working with Small Cell Technologies
With the increased demands on the network, service providers are investing in small cell solutions to 
help optimize and monetize consumer and business services on mobile devices across 3G and 4G 
networks.
Prime Network offers a portfolio of licensed small cells for home and office to support multiple 
deployment environments and technologies. 
A Home Node B (HNB) is the 3GPPs term for a 3G femtocell. It is a small low-power cellular base 
station that is very useful for use at home or a small business. It uses a broadband network to connect to 
the service provider’s network. 
NoteFemtocell is an important technology and service offering that enables new Home and Enterprise service 
capabilities for Mobile Operators and Converged Mobile Operators (xDSL/Cable/FFTH plus Wireless). 
The Femtocell network consists of a plug-n-play customer premise device generically called a Home 
NodeB (HNB) with limited range radio access in home or enterprise. The HNB will auto-configure itself 
with the network operators and the user can start making voice, data and multimedia calls.
The advantage of using HNB is superior coverage and capacity, especially while indoors. It also provides 
better voice quality and battery life. 
Viewing the Home Node B Gateway Details
The Home Node B Gateway is the HNB network access concentrator that is used to connect the Home 
Node B (HNBs)/Femto Access Point (FAP) to access the UMTS network through HNB Access Network. 
It aggregates Home Node-B or Femto Access Points to a single network element and then integrates them 
into the mobile operators of voice, data and multimedia networks. 
The HNB is connected to an existing residential broadband service and provides 3G radio coverage for 
3G handsets. 
Figure 27-4 depicts the topology of Home Node B Gateway.

Field Description
NNSF Timer The NAS (Non-Access Stratum) Node Selection Function (NNSF) timer of 
the HNB GW, which can be any one of the following values:
any value between 10 and 60
Disabled
NoteThe NNSF timer is used to store the IMSI and the relevant 
Global-CN-ID. Whenever the MSC sends the paging request with 
IMSI, the HNB GW stores the Global-CN-ID of the node that issued 
the request and the timer is started. The HNB GW will store the 
mapping of the IMSI to the Global-CN-ID until the timer expires.
IMSI Purge Timeout The purge timeout (in minutes) until which the IMSI White List received 
from the HMS/BAC during the HNB registration procedure must be 
maintained in the HNB GW. The field can display any one of the following 
values:
any value between 1 and 1440
Immediate
Disabled
This field defaults to 1440 (24 hours). The HNB GW waits for the specified 
time after all referenced HNBs have been de-registered before purging the 
records.
Alpha RTO The Alpha Retransmission Timeout (RTO) for the SCTP association 
between HNB and HNB GW, which can be any value between 0 and 65535.
Beta RTO The Beta Retransmission Timeout (RTO) for the SCTP association between 
HNB and HNB GW, which can be any value between 0 and 65535.
Max Incoming Streams The maximum number of incoming SCTP streams allowed on the HNB GW 
for an associated HNB-SCTP association. This can be any value between 1 
and 16 and defaults to 4.
Max Outgoing Streams The maximum number of outgoing SCTP streams allowed on the HNB GW 
for an associated HNB-SCTP association. This can be any value between 1 
and 16 and defaults to 4.
Max Re-Tx Association The maximum number of times the HNB GW is allowed to reach its peer. 
This number can be any value between 0 and 255, and defaults to 10.
NoteIf the number of retransmissions exceed the limit specified here, 
then the HNB GW considers the peer HNB unreachable and stops 
transmitting data. The SCTP association is automatically closed. 
Max Re-Tx Init The maximum number of times the HNB GW is allowed to retransmit INIT 
chunk after the T1-init timer expires. The HNB GW aborts the initialization 
process once the maximum number of attempts is reached. This can be any 
value between 0 and 255, and defaults to 5.
