To remove a particular selection-condition, a row-precedence value is
specified.
peer
pri_peer_name
Sets a configured Diameter peer, which is configured in Diameter
Endpoint configuration associated with PCC-Sp-Endpoint instance configuration,
as
primary in Diameter peer selection process for IPCF
configuration.
The
pri_peer_name is a pre-configured Diameter
peer in Diameter Endpoint configuration which is associated with a
PCC-Sp-Endpoint configuration and must be an alphanumerical string from 1
through 63 characters.
pri_peer_name allows punctuation marks.
row-precedence
row_prec_name
The row-precedence decides order of evaluation of the selection
conditions.
The
row_prec_name is an integer between 1 and 63.
Lower the value, higher is the priority of evaluation.
selection-condition
The selection-condition parameter is used to define Diameter SPR peer
selection conditon.
imsi
It indicates that the selection condition is based on subscriber IMSI.
mcc
mcc-string
It indicates that the selection condition is based on MCC component of
subscriber IMSI.
The
mcc-string can have one of the following
formats:
mccval1 or
mccval1-mccval2 . The first format compares
single MCC value and second one incorporates the range with mccval1 <=
mccval2.
The values for both mccval1 and mccval2 must be between 100 to 999.
mnc
mnc-string
It indicates that the selection condition is based on MNC component of
subscriber IMSI.
The
mnc-string can have one of the following
formats:
mncval1 or
mncval1-mncval2 . The first format compares
single MNC value and second one incorporates the range with mncval1 <=
mncval2.
The values for both mncval1 and mncval2 must be between 1 to 999.
msin
msin-string
It indicates that the condition is based on MSIN component of
subscriber IMSI.
The
msin-string can have following format:
msinval1-msinval2 . The format incorporates
the range with mccval1 <= mccval2.
The values for both mccval1 and mccval2 must be of maximum of 10
digits.
realm
realm-name
This keyword optionally defines the realm (domain) of a configured
primary Diameter peer, which is configured in Diameter Endpoint
configuration associated with PCC-Sp-Endpoint instance configuration, in
Diameter peer selection process for IPCF configuration.
realm_name is the realm (domain) of the
associated primary Diameter peer in Diameter Endpoint configuration which
associated with a PCC-Sp-Endpoint configuration. The
realm_name must be an alpha and/or numeric
string of 1 to 127 characters. The realm may typically be a company or service
name and it allows punctuation marks.
secondary-peer
sec_peer_name
Sets a configured Diameter peer, which is configured in Diameter
Endpoint configuration associated with PCC-Sp-Endpoint instance configuration,
as
secondary in Diameter peer selection process for IPCF
configuration.
The
sec_peer_name is a pre-configured Diameter
peer in Diameter Endpoint configuration which is associated with a
PCC-Sp-Endpoint configuration and must be an alphanumerical string from 1
through 63 characters.
sec_peer_name allows punctuation marks.
realm
sec_realm-name
This keyword optionally defines the realm (domain) of a configured
secondary Diameter peer, which is configured in Diameter
Endpoint configuration associated with PCC-Sp-Endpoint instance configuration,
in Diameter peer selection process for IPCF configuration.
sec_realm_name is the realm (domain) of the
associated primary Diameter peer in Diameter Endpoint configuration which
associated with a PCC-Sp-Endpoint configuration. The
sec_realm_name must be an alpha and/or
numeric string of from 1 to 127 characters. The realm may typically be a
company or service name and it allows punctuation marks.
Usage Guidelines
Use this command to nominate primary and secondary Diameter peers
amongst the peers configured under Diameter Endpoint Configuration instance
which is associated with a PCC-Sp-Endpoint configuration. When both primary and
secondary are down, the remaining Diameter peers are chosen based on their
configured weight in round robin manner.
When row-precedence and selection-conditions are not defined for peer
selection configuration, the row precedence value is assumed to be 64 (which is
the lowest). This is a deafult peer selection when all the other configured
selection conditions fail.
Multiple Diameter peers can be configured in a PCC-Sp-Endpoint
instance by entering this command multiple times.
Example
Assume the operator has two MCC-MNC combinations: 123-456 and 123-457
respectively for subscriber IMSI values. If operator wishes to divert
subscribers with these two different combinations to different SSC peers (say
ssc123456 and ssc123457) then the operator needs to use following commands
under PCC-Sp-Endpoint :
diameter peer-select row-precedence 4 selection-condition imsi mcc 123 mnc 456 peer ssc123456
diameter peer-select row-precedence 6 selection-condition imsi mnc 123 mnc 456 peer ssc223457
Following command nominates a pre-configured Diameter peer
dia1 as primary and
dia2 as secondary for Diameter peer selection
process in a PCC-Sp-Endpoint configuration instance.
