    Configuring Charging and Local Policy Profiles on a Broadband Gateway APN

    The Mobile Next Broadband Gateway applies different charging profiles to different types of users.

    Before you begin configuring charging profiles on a broadband gateway access point network (APN), you should have done the following:

    • Configured the chassis of the broadband gateway
    • Configured the interfaces of the broadband gateway
    • Configured the general APN parameters for the specific APN
    • Configured the charging details and quality-of-servce (QoS) local policy profiles for the broadband gateway

    To assign charging profiles to various types of users accessing an APN on the broadband gateway, you associate a user type with a charging profile name. The charging profile details for the APN users must be configured first. The default charging profile is used when a more specific profile does not apply. To assign local policy profiles for QoS purposes to an APN, you reference the name of the local policies group and its member profiles in the APN.

    Based on a comparison of public land mobile networks (PLMNs), the mobile user falls into one of three categories:

    • Home user—The subscriber, the gateway GPRS support node (GGSN) or Packet Data Network Gateway (P-GW), and Serving GPRS Support Node (SGSN) or Serving Gateway (S-GW) are all in the same PLMN.
    • Roaming user—The subscriber and GGSN or P-GW belong to the same PLMN, but the SSGN or S-GW are in a different PLMN.
    • Visiting user—The subscriber and SGSN or S-GW belong to the same PLMN, but the GGSN or P-GW are in a different PLMN.

    To configure charging profiles on a broadband gateway APN:

    1. Configure the default charging profile that is used by apn-1 when no other profile applies.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 charging]user@host# set default-charging-profile default-charging-profile-apn-1
    2. Configure the home user’s charging profile for apn-1.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 charging]user@host# set home-charging-profile home-charging-profile-apn-1
    3. Configure the roaming user’s charging profile for apn-1.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 charging]user@host# set roamer-charging-profile roamer-charging-profile-apn-1
    4. Configure the visiting user’s charging profile for apn-1.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 charging]user@host# set visitor-charging-profile visitor-charging-profile-apn-1
    5. Configure the broadband gateway to select the charging profile sent by the SGSN or S-GW first, sent by the RADIUS server next, or use the charging profiles statically configured locally for apn-1. These three options work in order you enter them.
      [edit unified-edge gateways ggsn-pgw MBG1 apn-services apns apn-1 charging]user@host# set profile-selection-order serving user@host# set profile-selection-order radius user@host# set profile-selection-order static

      Note: You do not have to use all three options.
