This manual provides an overview of the GSM Mobile Number Portability (G-Port) feature of the Oracle Communications EAGLE. The G-Port feature implements Mobile Number Portability for GSM networks according to ETSI GSM 03.66. In response to governmental mandates for telecommunication networks, this feature focuses on service provider number portability on GSM networks.

G-Port minimizes the challenges for GSM network operators while enabling them to meet regulatory obligations. G-Port supports the Signaling Relay Function (SRF) for direct and indirect routing. SRF-based Mobile Number Portability (MNP) processing examines MAP messages for ported numbers. For call-related messages, G-Port acts as an NP HLR for exported number by responding with a MAP SRI message; G-Port performs a message relay function for calls to imported numbers and non-call related messages.

The G-Port feature allows subscribers to be moved easily from one Home Location Register (HLR) to another. The G-Port feature applies to ANSI, ITU-I (international), and ITU-N (national) networks.

This manual is intended for anyone responsible for installing, maintaining, and using the G-Port feature of Oracle Communications EAGLE. Users of this manual and the others in the EAGLE family of documents must have a working knowledge of telecommunications and network installations.
