MME LAC Pool Area Configuration Mode Commands

MME LAC Pool Area Configuration Mode Commands
 
The MME LAC Pool Area Configuration Mode is used to create and manage the Location Area Code (LAC) pool areas.

hash-value
Configures the Visitor Location Register (VLR) hash value mapping for this pool area.
Product
MME
Privilege
Administrator
Syntax
hash-value { value | non-configured-values | range value to value } use-vlr vlr_name
no hash-value { value | non-configured-values | range value to value }
no
Removes the configured hash-value from the pool-area configuration.
value
Specifies the VLR hash value to be used with the configured VLR. value must be an integer from 0 through 999.
non-configured-values
Specifies that the VLR configured in this command is to be used non-configured hash values.
range value to value vlr_name
Specifies a range of hash values to use with the configured VLR as an integer from 0 through 999.
use-vlr
Specifies the VLR to be used with the hash value configuration in this command.
Usage
Use this command to configure hash values to be used with VLRs.
In a pool configuration, the MME selects the VLR that corresponds to the hash of the UE’s IMSI. If that VLR is inactive, the MME will use the default VLR (as defined by the non-configured-value option). If no default VLR has been configured, or if the default VLR is inactive, the MME selects any other available VLR from the pool.
If the chosen VLR is active at the time of selection and then subsequently becomes inactive when the request is sent to it, the current request fails. On the next request from the UE, the VLR selection mechanism is applied again. A VLR that failed previously will only be selected again if it became active since the earlier failure.
Example
The following command configures all hash values within a range of 0 to 500 to use a VLR named vlr1:
hash-value range 0 to 500 use-vlr vlr1
The following command configures hash values of 501 to use a VLR named vlr2:
hash-value 501 use-vlr vlr2
The following command configures all non-configured hash values to use a VLR named vlr3:
hash-value non-configured-values use-vlr vlr3
lac
Configures a 3G location area code or area codes that define this pool area.
Product
MME
Privilege
Administrator
Syntax
[ no ] lac { area_code } +
no
Removes a configured forbidden handover area code or area codes from this policy. If no location area code is specified, then all location area codes are removed.
area_code
Specifies an area code or area codes used to select a VLR for the pool area as an integer from 0 through 65535. Multiple area codes can be entered (up to 16 in a single line, separated by spaces).
note_smallImportant: A total of 16 area codes can be added in a single line or separately.
Usage
Use this command to configure 3G location-based area codes that define this pool area.
Example
The following command configures eight location-based area codes (1, 2, 3, 4, 5, 6, 7, 8) that define this pool area:
lac 1 2 3 4 5 6 7 8
plmn-id
Configures the Public Land Mobile Network (PLMN) identifier for the LAC pool area. The PLMN identifier is consists of the Mobile Country Code (MCC) and the Mobile Network Code (MNC).
Product
MME
Privilege
Administrator
Syntax
plmn-id mcc mcc_value mnc mnc_value
no plmn-id
no
Removes the configured PLMN identifier for the LAC pool area.
mcc mcc_value
Specifies the mobile country code (MCC) portion of the PLMN identifier as an integer from 100 through 999.
mnc mnc_value
Specifies the mobile network code (MNC) portion of the PLMN identifier as a 2- or 3-digit integer from 00 through 999.
Usage
Use this command to set the PLMN identifier for the LAC pool area.
Example
The following command configures the PLMN identifier with MCC value as 102 and MNC value as 20 for this MME service:
plmn-id mmc 102 mnc 20
