Example
The following command adds an LAI to this management object with an MCC of 111, an MNC of 22, and a LAC of 101:
lai mcc 122 mnc 22lac 101
 
sgw-address
Configures an S-GW IP address, supported S5/S8 protocol type, and selection weight used in a pool for S-GW selection.
Product
MME
Privilege
Administrator
Syntax
sgw-address ipv4_or_ipv6_address s5-s8-protocol { both | gtp | pmip } weight number
no sgw-address ipv4_or_ipv6_address s5-s8-protocol { both | gtp | pmip }
no sgw-address ipv4_or_ipv6_address s5-s8-protocol { both | gtp | pmip }
Removes the configured S-GW address from this TAI management object.
ipv4_or_ipv6_address
Specifies the IP address of the S-GW in the selection pool. ipv4_or_ipv6_address must be entered in dotted decimal notation (for IPv4 addresses) or colon-separated hexidecimal notation (for IPv6 addresses).
Up to 32 S-GW address can be configured per TAI management object.
s5-s8-protocol { both | gtp | pmip }
Specifies the S5/S8 interface type found between the configured S-GW and the P-GW.
both: Specifies that both the GTP and PMIP protocols are supported over the S5/S8 interface.
gtp: Specifies that the GTP protocol is supported over the S5/S8 interface.
pmip: Specifies that the PMIP protocol is supported over the S5/S8 interface.
weight number
Specifies the priority or weight of the S-GW address used during weighted round-robin selection within this TAI management object. number must be an integer value from 1 to 100.
Usage
Use this command to configure a pool of S-GW addresses used for S-GW selection.
Example
The following command configures an S-GW with an IPv4 address of 1.2.3.4, a supported S5/S8 protocol type of GTP, and a selection weight of 3:
sgw-address 1.2.3.4 s5-s8-protocol gtp weight 3
 
tai
Configures a Tracking Area Identifier (TAI) for this TAI management object.
Product
MME
Privilege
Administrator
Syntax
[ no ] tai mcc number mnc number { tac value } +
no
Removes a configured TAI from the TAI management object.
mcc number
Specifies the mobile country code (MCC) portion of a PLMN‘s identifier. number must be an integer value between 100 and 999.
mnc number
Specifies the mobile network code (MNC) portion of a PLMN‘s identifier. number can be configured to any 2 or 3 digit integer value between 00 and 999
tac value +
Specifies the Tracking Area Code portion of the TAI. value must be an integer from 1 to 65535. Up to 16 TAC values can be entered on a single line.
Usage
Use this command to configure one or more TAIs for this management object. Up to 16 TAIs can be configured per management object.
Example
The following command adds a TAI to this management object with an MCC of 111, an MNC of 22, and a TAC value of 1001:
tai mcc 122 mnc 22tac 1001
 
timezone
Configures the timezone to be used for the UE timezone in S11 and NAS messages.
Product
MME
Privilege
Administrator
Syntax
timezone { + | - } hours value [ minutes { 0 | 15 | 30 | 45 } ]
no timezone
Removes the time zone configuration from the management object.
+ | -
Specifies the offset direction from the Coordinated Universal Time (UTC).
hours value
Specifies the offset from UTC in hours. value must be an inter from 0 to 14.
minutes { 0 | 15 | 30 | 45 }
Optionally specifies the offset minutes added to the hours value.
Usage
Use this command to configure the time zone to be used for the UE timezone in S11 and NAS messages.
note_smallImportant: Time zone configurations at the TAI Management Object level take precedence over time zone configurations at the TAI Management Database level. If neither is configured, the system defaults to the MME time zone.
Example
The following command sets the time zone mapping for this management object to pus-3 hours and 15 minutes from UTC:
timezone + hours 3 minutes 15
 
zone-code
Configures a zone code for the management object.
Product
MME
Privilege
Administrator
Syntax
zone-code zc_id
no zone-code
no
Removes the configured zone-code from the management object.
zc_id
Identifies the zone code configuration instance. zc_id must be an integer from 1 to 65535.
Usage
note_smallImportant: While there is no limit to the number of zone codes that can be created, only 10 LACs per zone code can be defined.
Use this command to define zone code restrictions. Regional subscription data at the home subscriber service (HSS) is used to determine the regional subscription area in which the subscriber is allowed to roam. The regional subscription data consists of a list of zone codes which are comprised of one or more location areas (identified by a LAC) into which the subscriber is allowed to roam. Regional subscription data, if present in the Insert-Subscriber-Data-Request (IDR) and the Updae-Location-Answer (ULA) from the HSS, defines the subscriber's subscription area for the addressed MME. It contains the complete list (up to 10 zone codes) that apply to a subscriber in the currently visited PLMN. During the Location Update procedure, the zone code list is received in the ULA from the HSS. The zone code list is validated against the configured values in this command. If matched, then the Location Update procedure is allowed to proceed. If not matched, then the response is that the Network Node Area is restricted and the Location Update procedure fails.
Example
The following command sets the zone code for this management object to 1:
zone-code 1
