# HNB-GW Global Configuration Mode Commands

The 3G UMTS Home-NodeB Gateway Global Configuration Mode provides the global configurations for multiple HNB-GW services on a chassis to manage the access to the UMTS core network in a 3G UMTS network through a Femto node. This configuration mode is supported from StarOS 14.0 onward.

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
access-control-db

Configures the access control database parameters in HNB-GW Global configuration mode to control HNB and UE access to the HNB-GW node.

Syntax

    access-control-db imsi-purge-timeout {immidiate | dur }

    default access-control-db
    imsi-purge-timeout

default

Sets the default value to HNB-UE access control database on a chassis for HNB-GW Global configuration instance.

The default timeout duration for purging of the IMSI White List from the HNB-GW Access Control database is 24 hours. The HNB-GW service waits for 24 hours after all referenced HNBs have de-registered before purging the records.
immidiate

Sets the HNB-GW Global configuration instance to purge the HNB-UE access control database immediately after all referenced HNBs have de-registered.
imsi-purge-timeout dur

Sets the timeout duration (in minutes) for the access control database to wait before purging the IMSI values received as a White List from HMS/BAC.

After all HNBs have de-registered, the Access Control database on HNB-GW maintains the IMSI White List received from HMS/BAC during HNB registration procedure for the configured durations before purging the list.

dur is an integer from 1 through 1440.
Usage:

Use this command to configure the HNB-UE access control database parameters on a chassis for HNB-GW Global configuration instance.

This command sets the timeout duration to maintain the IMSI White List received from HMS/BAC during HNB registration procedure in HNB-GW Global configuration instance for the configured dur in minutes after de-registration of all referenced HNBs from HNB-GW node and then purge the database.
Example:
Following command sets the HNB-GW Global configuration instance to purge all IMSI records from HNB-UE access control database immediately after all referenced HNBs de-registered from HNB-GW service instance.

    access-control-db imsi-purge-timeout immidiate

Sets the HNB-GW Global parameter to page hybrid HNB from where the UE is registered.

always: Sets the system to ALWAYS page the hybrid HNBs from where the UE is registered. If the UE is not registered then it pages the hybrid HNBs irrespective of paging-area IE is received in paging messages.

never: Sets the system to page the hybrid HNBs from where the UE is registered. If the UE is not registered then it NEVER pages any hybrid HNB.

only-if-with-paging-area: Sets the system to ALWAYS page the hybrid HNBs from where the UE is registered. If the UE is not registered then it pages the hybrid HNBs only when paging-area IE is received in paging messages.

Sets the HNB-GW Global parameter to page hybrid HNB where HNB have IMSI in white-list.

always: Sets the system to ALWAYS page Hybrid HNB which have requested IMSI in whitelist. If no such Hybrid HNB is found, then system will page Hybrid HNBs irrespective of presence or absence of paging-area IE in paging messages.

never: Sets the system to ALWAYS page Hybrid HNB which have requested IMSI in whitelist. If no such Hybrid HNB is found, then system will NEVER page Hybrid HNBs irrespective of presence or absence of paging-area IE in paging messages.

sctp

Configures the SCTP-related parameters like timeout duration for various timers and cookie life over an IuH interface on a chassis for HNB-GW Global configuration instance.
Platform:

Product:

HNB-GW
Privilege:

Security Administrator, Administrator
Syntax

    sctp alpha-rto alpha_rto_dursctp beta-rto beta_rto_dursctp max-retx [init | path | assoc] max_retrysctp max-in-strms in_strmssctp max-out-strms out_strms

    default sctp {alpha-rto | beta-rto | max-retx [ init | path | assoc] | max-in-strms | max-out-strms }

default
Restores the SCTP parameters to default value in HNB-GW Global configuration instance. Default values for all parameters are as follows:

- alpha-rto: 5 seconds
- beta-rto: 10 seconds
- checksum-type: CRC32
- max-retx init: 5 retries
- max-retx path: 5 retries
- max-retx assoc: 10 retries
- max-in-strms: 4
- max-out-strms: 4

alpha-rto alpha_rto_dur

Sets the alpha retransmission timeout duration (in seconds) for SCTP association between HNB and HNB-GW as an integer from 0 through 65535. A “zero” value disables the timer in this configuration. Default: 5
beta-rto beta_rto_dur

Sets the beta retransmission timeout duration (in seconds) for SCTP association between HNB and HNB-GW an integer from 0 through 65535. A “zero” value disables the timer in this configuration. Default: 10
max-retx [ init | path | assoc ] max_retry

Sets the maximum number of retries allowed in SCTP states for SCTP association between HNB and HNB-GW.

init: Sets the maximum attempts allowed after T1-init timer expires. If the T1-init timer expires then the HNB-GW retransmits INIT chunk and re-start the T1-init timer without changing state. This is repeated up to the configured times with this configuration. After that, the HNB-GW aborts the initialization process. Default number of attempts max_retry for this state is 5.

path: Sets the maximum attempts allowed after T3-rtx timer expires. Each time the T3-rtx timer expires on any address, or when a HEARTBEAT sent to an idle address is not acknowledged within a RTO, the error counter of that destination address incremented. When the value in the error counter exceeds this protocol parameter of that HNB address, the HNB-GW marks the destination transport address as inactive. Default number of attempts max_retry for this state is 5.

assoc: Sets the maximum number of consecutive retransmissions to its peer is allowed. If the value of this counter exceeds the limit configured with this keyword the HNB-GW considers the peer HNB unreachable and stop transmitting any more data to it. The SCTP association is automatically closed when the peer endpoint becomes unreachable. Default number of attempts max_retry for this state is 10.

max_retry is an integer from 1 through 255.
max-in-strms in_strms

Sets the maximum number of inward SCTP streams allowed on HNB-GW for an associated HNB in an SCTP association as an integer from 1 through 16. Default: 4
max-out-strms out_strms

Sets the maximum number of outgoing SCTP streams allowed from HNB-GW for an associated HNB in an SCTP association as an integer from 1 through 16. Default: 4
Usage:

Use this command to configure the SCTP protocol messaging and session management parameters in SCTP association between HNB and HNB-GW.
Example:
The following command sets the maximum number of inward SCTP streams allowed to 4 on HNB-GW for the SCTP association:

    default max-in-strms

tnnsf-timer

Configures the NAS Node Selection Function (NNSF) timer (T-NNSF) which is used by the HNB-GW to store the IMSI and the relevant Global-CN-ID in the short term after Paging. This timer is used for Iu-Flex feature support.
Platform:

ASR 5000
Product:

HNB-GW
Privilege:

Security Administrator, Administrator
Syntax

    tnnsf-timer dur[no | default] tnnsf-timer

no

Disables/removes the configured timer value of NNSF timer (T-NNSF) for HNB-GW Global configuration instance.
default

Sets the timer value of NNSF timer (T-NNSF) for HNB-GW Global configuration instance to default value of 30 seconds.
tnnsf-timer dur

Configures the NNSF timer (in seconds) which is used by the HNB-GW to store the IMSI and the relevant Global-CN-ID as an integer from 10 through 60. Default: 30
Usage:

Use this command to configure the NNSF timer value in seconds for Iu-Flex support.

Whenever the MSC sends the paging request with IMSI, the HNB-GW stores the Global_CN_ID of the node which issued the paging request message for the given IMSI and HNB-GW starts the tnnsf-timer. HNBGW stores the mapping of IMSI to Global_CN_ID until the tnnsf-timer expires
Example:
The following command sets the NNSF timer value to 30 seconds on a chassis for HNB-GW Global configuration instance:

    default tnssf-timer
