2.4 G-Port SRI Query for Prepaid

Overview

The G-Port SRI Prepaid Feature enhances standard G-Port functionality by ensuring that all Send Routing Information (SRI) queries from the Prepaid Service Control Point (SCP) receive a direct response with portability routing information. This feature simplifies tariff determination and routing for prepaid subscribers, whether they are ported or not, by providing a meaningful G-Port response for every query.

Traditionally, only ported-out subscribers received an SRI acknowledgment (ack) from G-Port, while others were relayed to the Home Location Register (HLR). With this feature enabled, the Prepaid SCP always receives an SRI ack containing portability-related routing data for all matching queries, eliminating the need for Global Title Translation (GTT) for onward routing. It customizes Mobile Station Roaming Number (MSRN) formatting.
