El primer paso para el establecimiento de una conexión UMA, es el establecimiento de un túnel IPsec entre el terminal de usuario y el Security Gateway. El Security Gateway, recibe peticiones de establecimiento de túneles desde diversas direcciones IP. Durante el establecimiento del túnel, el usuario es autenticado mediante su IMSI (International Mobile Subscriber Identification) o MSISDN (Mobile Systems International Subscriber Identity Number) estando pues disponible en el Security Gateway, una relación de los túneles establecidos, la dirección IP desde la que se recibe la conexión y el IMSI o MSISDN del usuario que realiza dicha conexión.The first step in establishing a UMA connection, is the establishment of an IPsec tunnel between the User terminal and Security Gateway. The Security Gateway, receive requests to establish tunnels from various IP addresses. During the establishment of the tunnel, the user is authenticated through your IMSI (International Mobile Subscriber Identification) or MSISDN (Mobile Systems International Subscriber Identity Number) being then available on the Security Gateway, a list of the established tunnels, the IP address from the that the connection is received and the IMSI or MSISDN of the user that Make that connection.

A su vez, esta dirección IP habrá sido asignada al usuario por la plataforma de asignación de direcciones IP, que dispone por tanto de una relación de direcciones IP asignadas e identificadores de usuario.In turn, this IP address will have been assigned to the user through the IP address allocation platform, which It therefore has a list of assigned IP addresses and user identifiers

Mediante la modificación de algunos de estos elementos, y la inclusión de una nueva plataforma (la plataforma de localización UMA) encargada de solicitar y gestionar la información de todos ellos, es posible localizar a los usuarios independientemente de si se encuentran en cobertura GSM o UMA. En el caso de que un usuario se encuentre en cobertura UMA, el sistema lo localizará a partir de la dirección IP asignada, y mediante las distintas bases de datos disponibles, será capaz de determinar la dirección (calle, piso, localidad), desde la que el usuario se conecta, alcanzando una precisión equivalente al radio de cobertura de un punto de acceso Wireless LAN (un máximo de 100 metros, pero típicamente en el orden de los 50), proporcionando adicionalmente mayor precisión en la localización del usuario.By modifying some of these elements, and the inclusion of a new platform (the platform of UMA location) responsible for requesting and managing information of all of them, it is possible to locate users regardless of whether they are in GSM or UMA coverage. In the case that a user is in UMA coverage, the system will locate it from the assigned IP address, and by means of different databases available, will be able to determine the address (street, floor, town), from which the user connect, reaching an accuracy equivalent to the coverage radius of a Wireless LAN access point (a maximum of 100 meters, but typically in the order of 50), additionally providing greater accuracy in user location.
