db_name

Specifies the name of the management database. If the name does not refer to an existing database, a new database is created. db_name is an alphanumeric string of 1 through 64 characters.

Usage Guidelines

Use this command to create a new, or enter the existing MME HeNB-GW management database. This command enables configuration for the MME to distinguish between an HeNB-GW and an eNodeB.

In case of S1-based handovers to Home eNodeBs served by a HeNB-GW, the lookup at the MME for the target eNodeB based on global eNodeB id cannot be completed, as the MME is aware of only the HeNB-GW. In those cases, an additional lookup needs to be performed based on the TAI, in order to find the HeNB-GW serving the Home eNodeB. The S1 Handover request message will then be sent to the HeNB-GW and forwarded to the correct Home eNodeB in order to prepare the target RAN node for handover.

One HeNB-GW management database is allowed per LTE Policy.

A maximum of 8 HeNB-GWs can be configured within this management database.

Entering this command results in the following prompt: 
[context_name]hostname(henbgw-mgmt-db)#

MME HeNB-GW management database commands are defined in the LTE MME HeNB-GW Management Database Configuration Mode Commands chapter.

Examples

The following command enters the existing LTE MME HeNB-GW Managment Database Configuration Mode (or creates it if it does not already exist) for the database named henbgw_db1:

Privilege

Mode

Exec > Global Configuration > LTE Policy Configuration

Entering the above command sequence results in the following prompt: 

[local]host_name(lte-policy)#

Syntax

mme paging cache { size  cache_size | timeout  time }  
default mme paging cache { size  | timeout  }

default

Resets either the paging cache size or the paging cache timer to default settings.

size cache_size

cache_size : Enter an integer from 0 to 10000 to specify the maximum number of Tracking Area Code (TAC) entries to be cached.

Entering the '0' value disables caching and should be followed by use of the mme paging cache clear command (in the Exec mode). See the Example section.

Default cache size = 5000 TAC entries per SessMgr.

timeout time

time : Enter an integer from 1 to 1440 to specify the number of minutes that each Tracking Area Code (TAC) entry remains valid.

A lower cache timeout helps to refresh the cache frequently and enables this functionality to quickly adapt to changes in the network. We recommend the timeout value be less than the expected eNodeB flap frequency; for example, if the eNodeBs connected to the MME are expected to disconnect and reconnect every 10 minutes (due to network issues), then the timeout configuration should be less than 10 minutes.

Default timeout = 5 minutes.

Usage Guidelines

Both size and timeout must be configured to enable paging cache optimization. The mme paging cache command must be entered twice, once for each parameter.

Examples

Use the following configuration to set the paging cache timeout to match the eNodeB flap frequency of 10 minutes: 
mme paging cache timeout 10

Use the following configuration to set the paging cache size to 100: 

mme paging cache size 100
Use the following configuration to set the paging cache size to 0 (to disable caching):

Removes the specified management database from the system.

-noconfirm

db_name

Specifies the name of the management database. If the name does not refer to an existing database, a new database is created. db_name is an alphanumeric string of 1 through 64 characters.

Usage Guidelines

Enter the TAI Management Database Configuration Mode for an existing or newly defined database. This command is also used to remove an existing database.

On the S4-SGSN, once you have created a new, or accessed an existing, TAI Management database, a TAI Management Object must be created or accessed and the S-GWs and their associated RAIs configured using the rai and sgw-address commands. Refer to the LTE TAI Object Configuration Mode chapter for details on these two commands.

A maximum number of 32 TAI-DBs is supported in this release.
