LTE Emergency Profile Configuration Mode Commands


LTE Emergency Profile Configuration Mode Commands
 
 
This mode configures parameters supporting the IMS emergency bearer services. Connectivity to an emergency PDN is statically configured in this mode.
 
 
ambr
Configures the maximum aggregated uplink and downlink bitrate values for this profile.
Product
MME
Privilege
Administrator
Syntax
ambr max-ul bitrate max-dl bitrate
no ambr
no
Removes the aggregated maximum bitrate (AMBR) configuration for this emergency profile.
max-ul bitrate
Configures the maximum aggregated bitrate value for the uplink. bitrate must be an integer value from 0 to 1410065408.
max-dl bitrate
Configures the maximum aggregated bitrate value for the downlink. bitrate must be an integer value from 0 to 1410065408.
Usage
Use this command to configure uplink and downlink maximum aggregated bitrate values to be shared across all non-guaranteed bitrate bearers established for the emergency session.
Example
The following example configures the uplink AMBR value to 2000 bps and the downlink AMBR value to 2000 bps:
ambr max-ul 2000 max-dl 2000
 
apn
Configures the name and PDN type of the access point name (APN) used for emergency PDN connections.
Product
MME
Privilege
Administrator
Syntax
apn apn_name pdn-type { ipv4 | ipv4v6 | ipv6 }
no apn
no
Removes the selected APN from the profile.
apn_name
apn_name specifies the name for a pre-configured APN profile to associate with this LTE emergency profile. For more information on APNs, refer to the apn command in the Context Configuration Mode Commands chapter.
pdn-type { ipv4 | ipv4v6 | ipv6 }
Configures the packet data network type supported by the APN and this profile.
ipv4: Specifies that the PDN supports IPv4 network traffic.
ipv4v6: Specifies that the PDN supports both IPv4 and IPv6 network traffic.
ipv6: Specifies that the PDN supports IPv6 network traffic.
Usage
Use this command to select the APN to be used for emergency bearer services. APNs are configured through the APN configuration mode. For more information regarding APN configuration mode commands, refer to the APN Configuration Mode Commands chapter.
Example
The following command specifies that the APN named apn-3.com is to be used for emergency bearer services and that the PDN supports IPv4 traffic only:
apn apn-3.com pdn-type ipv4
 
end
Exits the current mode and returns to the Exec Mode.
Product
All
Privilege
Administrator
Syntax
end
Usage
Change the mode back to the Exec mode.
 
exit
Exits the current mode and returns to the previous mode.
Product
All
Privilege
Administrator
Syntax
exit
Usage
Return to the previous mode.
 
pgw
Statically configures a P-GW to support emergency bearer services for this profile.
Product
MME
Privilege
Administrator
Syntax
pgw fqdn fqdn
pgw ip-address address protocol { both | gtp | pmip } weight value
no pgw { fqdn | ip-address address }
no fqdn
Removes the specified P-GW FQDN or IP address from this profile.
fqdn fqdn
Specifies the domain name of the P-GW. fqdn must be from 1 to 256 alpha and/or numeric characters.
note_smallImportant: A maximum of one P-GW FQDN configuration is allowed per profile.
ip-address address
Specifies the IP address in IPv4 or IPv6 notation for the P-GW. For IPv4, address must be specified in dotted decimal notation. For IPv6, address must be specified in colon separated notation.
note_smallImportant: A maximum of four P-GW IP address configurations are allowed per profile.
protocol { both | gtp | pmip }
Specifies the protocol the P-GW supports. Options are:
both: Specifies that both the GTP and PMIP protocols are supported.
gtp: Specifies that only GTP is supported.
pmip: Specifies that only PMIP is supported.
weight value
Assigns a weight to P-GW IP address to use as a preferred P-GW. value must be an integer from 1 through 100. Lowest value has the least preference.
Usage
Use this command to statically configure the P-GW used to support emergency bearer services through this profile.
Example
The following command configures the P-GW supporting emergency bearer services for this profile as “pdn-911.gov”:
pgw fqdn pdn-911.gov
The following command configures the P-GW supporting emergency bearer services for this profile as having an IPv4 address of 1.2.3.4, supporting GTP only, and having a weight of 10:
pgw ip-address 1.2.3.4 protocol gtp weight 10
 
qos
Configures the quality of service parameters for the emergency bearer service.
Product
MME
Privilege
Administrator
Syntax
qos qci qci arp arp_value preemption-capability { may | shall-not } vulnerability { not-preemptable | preemtable }
no qos
qci qci
Specifies the QoS Class Identifier for the emergency bearer profile. qci must be an integer value from 0 to 255.
arp arp_value
Defines the address retention priority value.
arp_value: Enter a value from 1 to 15.
preemption-capability { may | shall-not }
Specifies the preemption capability flag. Options are:
may: Bearer may be preempted
shall-not: Bearer shall not be preempted
vulnerability { not-preemptable | preemptable }
Specifies the vulnerability flag. Options are:
not-preemptable: Bearer cannot be preempted.
preemptable: Bearer can be preempted.
Usage
Use this command to set the QoS APR and QCI parameters for the emergency bearer configuration.
Example
The following command sets the QCI number to 7, the ARP value to 2 the preemption capability to “may”, and the vulnerability flag to “pre-emptable”:
qos qci 7 arp 2 preemption-capability may vulnerability preemptable
 
ue-validation-level
Configures the type of UE that can use the emergency bearer service through the profile.
Product
MME
Privilege
Administrator
Syntax
ue-validation-level { auth-only | full | imsi | none }
default ue-validation-level
default
Returns the command to its default setting of “none”.
{ auth-only | full | imsi | none }
Specifies the type of UE allowed to use the emergency bearer service. Options are:
auth-only: Specifies that UEs that have been authenticated are allowed to use the emergency bearer service. These UEs may be in a limited service state in that they may be in an area with restricted service or where they are restricted from services. Enabling this option also causes subscription and location validation to be bypassed.
full: Specifies that only UEs that have been authenticated and have successfully passed subscription and location validation are allowed to use the emergency bearer service. Enabling this option indicates that only UEs that are capable of normal attach procedures will be allowed to use the emergency bearer service.
imsi: Specifies that UEs with an International Mobile Subscriber Identity (IMSI) are allowed to use the emergency bearer service regardless of authentication. Even if authentication fails, the UE is granted access.
none: Specifies that all UEs are allowed to use the service. This is the default value for the command.
Usage
Use this command to indicate which UEs can use the emergency bearer service through this profile.
Example
The following command configures the type of UE allowed to use the emergency bearer service to “IMSI required, authentication optional”:
ue-validation-level imsi
