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:

  • Access profile

  • Dynamic profile

  • Anchor point interface

  • Address pool

To configure fixed wireless access on the BNG:

  1. Specify the name of the pseudowire physical interface that anchors all incoming GTP-U (S1-U interface) tunnels on the BNG.Note

    The BNG supports only a single anchor point.

  2. 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.
    1. (Optional) Associate an authentication or accounting profile with the APN that specifies authentication or accounting parameters.
    2. (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.
    3. (Optional) Specify the type of data sent to the APN.Note

      Only the ipv4 type is supported.

    4. (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.
    5. Associate a dynamic profile with the APN to create the dynamic fixed wireless interface.Note

      Services such as CoS and firewall filters are applied as part of the DHCP configuration.

    6. (Optional) Specify the name of the address pool for IPv4 addresses assigned to the APN.Note

      Only IPv4 addresses are supported.

    7. (Optional)
  3. 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.
  4. 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 and the S1-U interface address as 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 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:
