Configuring the Peer MME Address (S4 Only, Optional)
For operators wishing to bypass DNS resolution to obtain the peer EPC MME address, the SGSN supports the local
configuration of a peer MME address for a given MME group (LAC) and MME code (RAC).
configuration of a peer MME address for a given MME group (LAC) and MME code (RAC).
Use the following procedure to configure the peer MME address:
Step 1
Access Call Control Configuration Mode and create a call-control-profile.
Step 2
Configure the peer MME Group ID LAC and RAC values or the TAC.
Step 3
Specify a
local
preference for selection of the peer MME address.
Step 4
Specify the local MME address to use for lookup instead of a DNS query.
Step 5
Specify the interface type to use when communicating with the peer MME. The interface must be
s3
.
Example Configuration
config
call-control-profile <cc-profile-name>
peer-mme { mme-groupid <lac_value> mme-code <rac_code> | tac tac } prefer local
address <ipv4_address | ipv6_address> interface { gn [ s3 ] | s3 [ gn ] }
address <ipv4_address | ipv6_address> interface { gn [ s3 ] | s3 [ gn ] }
end
Notes:
The
tac
keyword can be used instead of the
mme-groupid
and
mme-code
parameters to configure the Tracking
Area Code (TAC) of the target eNodeB that maps to the peer MME address. The TAC is used by the S4-SGSN
for UTRAN to E-UTRAN (SGSN to MME) SRNS relocation across the S3 interface. Configuration of the
for UTRAN to E-UTRAN (SGSN to MME) SRNS relocation across the S3 interface. Configuration of the
tac
is valid only if SRNS relocation first has been configured in Call Control Profile Configuration Mode via the
srns-inter
and/or
srns-intra
commands.
