How to Increase Diameter's Reservation Quota in order to Reduce Traffic between SLC and GGSN (Doc ID 1289523.1)

Last updated on OCTOBER 14, 2022

Applies to:

Oracle Communications Network Charging and Control - Version 3.1.0 to 4.2.0 [Release 3.1.0 to 4.2]
Information in this document applies to any platform.



SLC: Service Logic Controller
VWS: Voucher and Wallet Server

By default, SLC uses an interim reservation of 180 units* as defined in VWS (see below note) and each unit equals to 1 KB. As a result, for every 180 KB upload/download, SLC has to be queried for reservation. In most occasions, it causes relatively high number of messages between SLC and GGSN** and consequently adds unnecessary delays for accessing prepaid data subscribers.

Quota increase is required to remedy this problem, e.g. to increase quota into 1,800 KB. This document provides way to achieve it.

*) It's defined in VWS's eserv.config under CCS section:
CCS.reservationHandler.maxReservationLength = 180

**) The Gateway GPRS Support Node (GGSN) is a main component of the GPRS network. The GGSN is responsible for the interworking between the GPRS network and external packet switched networks, like the Internet and X.25, WiMax networks.
