MAP Gateway

Modulo’s MAP Gateway is a powerful flexible bridge between the GSM/UMTS signaling network and modern web applications. It provides an HTTP/REST interface for web developers to embed a mobile network function in their application.



What is a MAP Gateway?

MAP Gateway is a mobile network element that provides the ability to interact with network elements such as the HLR, the VLR/MSC and the SMSC, for easy creation of new core network services. MAP stands for Mobile Application Part, a protocol used in mobile network communication.

Modulo’s MAP Gateway

Modulo’s MAP Gateway is a critical GSM/UMTS network element. enables fast and easy creation of Value Added Services (VAS) for 2G/3G mobile networks with a simple REST/HTTP interface.

The MAP Gateway’s RESTful HTTP interface allows any web developer to create new services for 2G and 3G mobile networks, making the development and deployment process faster and cheaper compared to traditional SS7-based development.

Modulo’s MAP Signaling Gateway’s Horizontally scalable architecture provides high reliability and extensive scope to increase system throughput in pace with network growth. Supporting SS7 & SIGTRAN with no vendor specific dependency, it can scale from 4 LSL up to 744 LSL or the equivalent in SIGTRAN bandwidth.

Our MAP Gateway does not implement service logic but could potentially be customized to do so. Typically the logic of services provided to subscribers is determined by external applications that interact with mobile networks through the MAP Gateway using a common IP interface.

    RESTful run-mode in the Modulo MAP Gateway

    The RESTful run-mode allows a 3rd party web application server to implement an intelligent application by exchanging Json objects through RESTful HTTP requests.

    The MAP Gateway Restful mode allows HTTP interfaces to implement intelligent applications on the network

    Use Cases

    Wi-Fi Authentication Gateway

    A use case where the MAP-GW translates a RADIUS authentication request to a MAP Authentication procedure with the HLR.
