Sets the duration (in seconds) after which Selective Acknowledgement chunk is sent to HNB from HNB-GW in SCTP association. The SACK chunk is sent to the HNB to acknowledge received DATA chunks and to inform the HNB of gaps in subsequently received DATA chunks.

sack_dur is an integer from 0 through 5. A “zero” value disables the parameter.

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 SCTP COOKIE life to 600 milliseconds on HNB-GW for the SCTP association:
default sctp cookie-life
sctp bind

Configures the SCTP IP address and port that is used for binding the SCTP socket to communicate with the Home-NodeB over an Iuh interface within an HNB-GW service.

Platform:

ASR 5000

Product:

HNB-GW


Privilege:

Security Administrator, Administrator


Syntax 
sctp bind { address address | port port_num }[ default | no ] sctp
bind { address | port }
default

Sets the SCTP port to the default value of 600.

address address

Specifies the IP address of the HNB-GW Iuh interface in IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal notation.

port port_num

Specifies the SCTP port number to communicate with the Home-NodeBs using Iuh interface as an integer form 1 through 65535.


Usage:

Use this command to assign the SCTP IP address and port with SCTP socket on HNB-GW to communicate with the Home-NodeB using Iuh interface. This SCTP configuration provides the IP-address and listen port where HNB-GW service shall bind to listen for incoming SCTP associations from HNB.


Example:
The following command sets the SCTP port number 999 on HNB-GW to listen from Home-NodeB over Iuh interface:
sctp bind port 999
The following command sets the SCTP address 10.2.3.4 of HNB-GW to use with Home-NodeB over Iuh interface:
sctp bind address 10.2.3.4
sctp connection-timeout

Configures the SCTP connection timeout duration to explicitly remove the SCTP association with a non-responsive HNB in an HNB-GW service.

Platform:

ASR 5000

Product:

HNB-GW


Privilege:

Security Administrator, Administrator


Syntax 
sctp connection-timeout dur[ default | no ] sctp
connection-timeout
no

Disables the connection time out configuration on HNB-GW service.

default

Restores the connection timeout duration value to its default value of 10 seconds.

dur

Sets the connection timeout duration (in seconds) after which the association is explicitly removed. In case of an HNB de-registration scenario, the HNB-GW waits for configured amount time before initiating the procedure to clear the SCTP association.

dur is an integer from 5 through 30. Default: 10


Usage:

Use this command to configure the minimum duration value before removing the SCTP association between a non-responding HNB and HNB-GW. If HNB registration not happened within the configured period after the SCTP association is established then the SCTP association is explicitly removed. In a scenario where an HNB de-registered due to any reason, the HNB-GW waits for the configured amount of time before initiating the procedure to clear the SCTP association.


Example:
The following command sets the SCTP connection timeout duration to 15 second on HNB-GW after expiry of which the SCTP association is removed:
sctp connection-timeout 15
sctp heart-beat-timeout

Configures the SCTP heartbeat timer parameters for SCTP connection over an IuH interface in an HNB-GW service instance.

Platform:

ASR 5000

Product:

HNB-GW


Privilege:

Security Administrator, Administrator


Syntax 
sctp heart-beat-timeout dur[ default | no ] sctp
heart-beat-timeout
no

Disables the heartbeat timer configuration for SCTP over IuH in HNB-GW service instance.

default

Restores the default time out value for heartbeat timer to 30 seconds.

dur

Sets the heartbeat timer timeout duration (in seconds) after which the next heartbeat command is sent to HNB from HNB-GW in SCTP over an IuH interface. In an HNB de-registration scenario, the HNB-GW waits for configured amount time before initiating the procedure to clear the SCTP association.

dur is an integer from 1 through 300. Default: 30


Usage:

Use this command to configure the minimum duration value before retransmitting the HEARTBEAT chunk to HNB from HNB-GW in SCTP transmission. By default HNB-GW monitors the reachability of the idle HNBs by sending a HEARTBEAT chunk periodically to the HNB address.

Each time the HEARTBEAT timer expires on any address, or when a HEARTBEAT sent to an idle address is not acknowledged within a Retransmission Timeout duration, the error counter of that HNB incremented.

When the value in the error counter exceeds the protocol parameter for maximum retransmission for that destination address, the HNB-GW mark the destination HNB as inactive and a notification is sent to the upper layer.


Example:
The following command sets the SCTP HEARTBEAT timeout duration to 15 second on HNB-GW after expiry of which the HNB-GW retransmits the HEARTBAT chunk to HNB over SCTP association:
sctp heart-beat-timeout 15
security-gateway aaa

This functionality is part of SeGW configuration support in an HNB-GW service.

CAUTION:

This is a critical configuration and need to be configured carefully when Security Gateway (SeGW) functionality required on HNB-GW service.


Example:
The following command associates an AAA server group named sec_gw_grp1 with HNB-GW service to use specific AAA authentication parameters in first phase of authentication and another AAA server group named sec_gw_grp2 to use different AAA authentication parameter in second phase of authentication. Both AAA server groups are configured in same context named SeGW_ctx1:
security-gateway aaa
authentication first-phase context SeGW1 aaa-group sec_gw_grp1security-gateway aaa
authentication second-phase context SeGW1 aaa-group sec_gw_grp2
The following command disables a previously configured AAA authentication parameter for first phase of authentication:
no security-gateway

no security-gateway bind
no

Removes a previously configured IPSec IP address use for binding the IKEv2 IPSec tunnel (local bind address) to communicate with the Home-NodeBs using Iuh interface.

bind address address

Specifies the IP address for the Iuh interface for the IPSec tunnel. This is the IP address where the HNB-GW service is bound and that is provided to the Home-NodeB during HNB-GW discovery.

The IP address is expressed in IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal notation.

crypto-template cryp_name

Specifies the Crypto-map template to be used for IPsec IKEv2 tunneling for the interface configured as an Iuh.

cryp_name specifies the name of the pre-configured Crypto-map template which is configured in Crypto-Map Template Configuration mode and associated with the HNB-GW service to create an IPSec tunnel with a Home-NodeB during HNB-GW discovery procedure over an Iuh interface.

context ctx_name

Specifies the name of the pre-configured context in which the Security Gateway service is configured. By default this command uses the HNB-GW service context for the security Gateway configuration.


Usage:

Use this command to associate or tie the HNB-GW service to a specific logical IP address that is used for binding the Iuh socket to communicate with the Home-NodeB using IPSec tunnel. A maximum of one IP address can be configured with this command for one HNB-GW service.

The HNB-GW passes the IP address during setting up the HNB-GW discovery procedure with the Home-NodeB.

CAUTION:

This is a critical configuration. The HNB-GW service cannot be started without this configuration. Any change to this configuration would lead to restarting the HNB-GW service and removing or disabling this configuration stops the HNB-GW service.


Example:
The following command binds the logical IP interface with the address of 10.2.3.4 to the HNB-GW service using existing IPsec Crypto-Map template crypto1 to establish IPSec tunnel with Home-NodeB:
security-gateway bind
address 10.2.3.4 crypto-template crypto1
The following command disables a binding that was previously configured:
security-gateway bind address

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) from HNB-GW service instance.

default

Sets the timer value of NNSF timer (T-NNSF) for HNB-GW service 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 in an HNB-GW service instance:
default tnssf-timer
ue registration-timeout

Configures the UE registration timeout duration to de-register the connected UE from an HNB-GW service.

Privilege:

Security Administrator, Administrator


Syntax 
ue registration-timeout dur[ default | no ] ue
registration-timeout
no

Disables the UE registration timeout duration and explicitly de-registers UE from the HNB-GW service.

default

Restores the UE registration timeout duration value to its default value of 120 seconds.

dur

Sets the UE registration timeout duration (in seconds) after which the UE is de-registered from HNB-GW. In a scenario when all Iu connections are released for a subscriber, the HNB-GW service de-registers the UE after the configured duration only.

dur is an integer from 60 through 300. Default: 120


Usage:

Use this command to configure the minimum duration value before de-registering the UE when subscriber fails to establish the Iu connection. If subscriber’s Iu session does not established before configured period then UE is de-registered. Also in a scenario where all Iu connections are released for a subscriber, the HNB-GW service waits for configured period before starting UE deregistration procedure.


Example:
The following command sets the UE registration timeout duration to 150 second on HNB-GW after expiry of which the UE is de-registered:
ue registration-timeout 150
