The
timeout emergency-inactivity
command specifies the timeout duration, in seconds, to check
inactivity on the emergency session. <
seconds
> must be an integer value from 1 through 3600.
By default, emergency inactivity timeout is disabled (0).
The
p-cscf fqdn
command configures the P-CSCF FQDN server name for the APN. <
fqdn
> must be a string
from 1 to 256 characters in length.
P-CSCF FQDN has more significance than CLI-configured P-CSCF IPv4 and IPv6 addresses.
Configuring Common Gateway Access Support
This section describes some advance feature configuration to support multiple access networks (CDMA, eHRPD ,and
LTE) plus a GSM/UMTS for international roaming with the same IP addressing behavior and access to 3GPP AAA for
subscriber authorization. Subscribers using static IP addressing will be able to get the same IP address regardless of the
access technology.
This configuration combines 3G and 4G access technologies in a common gateway supporting logical services of HA,
P-GW, and GGSN to allow subscribers to have the same user experience, independent of the access technology
available.
Important:
This feature is a license-enabled support and you may need to install a feature specific session license
on your system to use some commands related to this configuration.
These instructions assume that you have already configured the system level configuration as described in
System
Administration Guide
and P-GW service.
To configure the S6b and other advance features:
1.
Configure Diameter endpoint by applying the example configuration in the
Diameter Endpoint Configuration
section.
2.
Create or modify AAA group by applying the example configuration in the
AAA Group Configuration
section.
3.
Modify P-GW service to allow authorization with HSS by applying the example configuration in the
Authorization over S6b Configuration
section.
4.
Optional
. Create and associate DNS client parameters by applying the example configuration in the
DNS Client
Configuration
section.
5.
Optional
. Modify P-GW service to accept duplicate calls when received with same IP address by applying the
example configuration in the
Duplicate Call Accept Configuration
section.
6.
Verify your S6b configuration by following the steps in the
Common Gateway Access Support Configuration
Verification
section.
7.
Save your configuration as described in the
Verifying and Saving Your Configuration
chapter.
Diameter Endpoint Configuration
Use the following example to configure the Diameter endpoint:
configure
context <
pgw_ctxt_name
> -noconfirm
diameter endpoint <
s6b_endpoint_name
>
origin host <
host_name
> address <
ip_address
>
