How to Configure Fixed Wireless Access
The fixed wireless access configuration enables the SAEGW on the BNG. At a minimum you must configure an APN, the control plane and the data plane.
The following procedure assumes that you have configured separately any of the following that apply for your APN:
Anchor point interface
To configure fixed wireless access on the BNG:
- Specify the name of the pseudowire physical interface
that anchors all incoming GTP-U (S1-U interface) tunnels on the BNG.
The BNG supports only a single anchor point.user@host# set anchor-point anchor-point-name
- Define an access point name for the user equipment by
specifying the connection and service parameters that the subscriber’s
device can use to connect to the PGW to access a PDN.
- (Optional) Associate an authentication or accounting profile
with the APN that specifies authentication or accounting parameters.user@host# set aaa-profile aaa-profile-name
- (Optional) Specify one or more authentication parameters
that the BNG sends to the external AAA server for subscribers using
this APN. You configure details about the external server in the access
profile that you associate with the APN. Some networks might not use
this authentication, because the HSS has already authenticated the
UE and determined subscriber access. Other networks might not use
this because they use Diameter for online charging.user@host# set authentication password passworduser@host# set authentication username-include delimiter delimiteruser@host# set authentication username-include domain-name domain-nameuser@host# set authentication username-include imsiuser@host# set authentication username-include meiuser@host# set authentication username-include msisdnuser@host# set authentication username-include user-prefix user-prefix
- (Optional) Specify the type of data sent to the APN.
Only the ipv4 type is supported.user@host# set apn-data-type type
- (Optional) Specify a text description for the APN. You
can use this to provide more information about the APN than its name
alone can convey. The description for an APN appears in subscriber
profiles in the HSS database.user@host# set description description
- Associate a dynamic profile with the APN to create the
dynamic fixed wireless interface.
Services such as CoS and firewall filters are applied as part of the DHCP configuration.user@host# set dynamic-profile dynamic-profile
- (Optional) Specify the name of the address pool for IPv4
addresses assigned to the APN.
Only IPv4 addresses are supported.user@host# set ipv4-address-pool pool-name
- (Optional)user@host# set routing-instance routing-instance-name
- (Optional) Associate an authentication or accounting profile with the APN that specifies authentication or accounting parameters.
- Configure the control plane by specifying the name of the MME and the IPv4 address of the S11 interface on the BNG. The S11 interface is the reference point or connection between the MME and the SAEGW on the BNG for control packets.
- Configure the data plane by specifying the name of the eNodeB and the IPv4 address for the S1-U interface on the BNG. The S1-U interface is the reference point or connection between the eNodeB and the SAEGW on the BNG for subscriber data traffic.
For example, the following configuration specifies the S11 interface address as 192.0.2.30 and the S1-U interface address as 192.0.2.100. The pseudowire anchor is ps0. The APN is named internet-basic; it has both an access profile for RADIUS parameters and a dynamic client profile attached. The authentication password is $ABC123. The username includes the domain name example.net and the subscriber’s IMSI. The data type is the required IPv4. A descriptive string, fwa-basic-subscribers-phoenix, is associated with the APN.
The APN uses the default routing instance, because no other routing instance is configured. IP addresses are supplied by RADIUS, because the configuration does not specify a local pool.
The dynamic profile that you attach to the APN creates the dynamic interface for fixed wireless access. The following configuration is a simple example:
The anchor point interface configuration is also very simple. For example:
