Configuring GTP Prime for Charging

To configure GPRS tunneling protocol (GTP) Prime to transfer Charging Data Records (CDRs), perform these tasks:

Configuring GTP Prime for Transferring CDRs

CDRs are transferred to a charging gateway using GTP Prime or logged to a Routing Engine hard disk and eventually retrieved by a charging gateway using FTP.

To configure global GTP Prime options to transfer CDRs:

  1. Specify that you want to configure GTP Prime properties for the gateway called MBG1.
    [edit]user@host# edit unified-edge gateways ggsn-pgw MBG1 charging gtpp
  2. Specify the destination port number of the charging gateway function (CGF) server.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp]user@host# set destination-port port-number
  3. Specify the source interface from which GTP Prime packets will be sent.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp]user@host# set source-interface interface-name <ipv4-address>
  4. Specify the transport protocol.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp]user@host# set transport-protocol (udp | tcp)
  5. Specify the GTP Prime version.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp]user@host# set version (v0 | v1 | v2)
  6. Specify the GTP Prime header type.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp]user@host# set header-type (long | short)
  7. Specify that path management is disabled. This option cannot be used with the echo request interval.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp]user@host# set no-path-management
  8. Specify the GTP Prime echo request interval for path management.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp]user@host# set echo-interval seconds
  9. Specify the number of retries of GTP Prime messages upon timeout.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp]user@host# set n3-requests requests
  10. Specify the response timeout value for the GTP Prime request message.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp]user@host# set t3-response response-interval
  11. Specify the time to wait before declaring a CGF as down.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp]user@host# set down-detect-time seconds
  12. Specify the time after which to retry the connection to the CGF server.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp]user@host# set reconnect-time seconds
  13. Specify the maximum number of Data Record Transfer (DRT) messages awaiting an acknowledgment.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp]user@host# set pending-queue-size queue-size

Configuring GTP Prime Peers

CDRs are transferred to a charging gateway using GTP Prime. The charging gateway is the GTP Prime peer. The charging gateway peer inherits the global GTP Prime values. You configure the GTP Prime peer only if you want to override any of the global GTP Prime values.

To configure the GTP Prime peer to transfer CDRs:

  1. Specify the name of the CGF peer for which you are configuring GTP Prime properties. Use this peer name to configure the peer order in the transport profile.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp]user@host# edit peer peer-name
  2. Specify the destination IPv4 address of the CGF peer.
    [edit unified-edge gateways ggsn-pgw MBG1 charging gtpp peer peer-name]user@host# set destination-ipv4-address ip-address
  3. (Optional) Specify any of the global GTP Prime options that you want to override for this charging gateway.
