Abstract

A server of a wireless operator creates a roaming list based on a user's roaming plan and sends the roaming list to the user's wireless device. The roaming list includes a list of public land mobile networks (PLMNs). When the user travels away from their home wireless network to another geographic area, the wireless device scans based on the roaming list for radio signals. The roaming list contributes to user satisfaction because timely attachment to a radio network while away from home occurs efficiently since the wireless operator creates the roaming list based on both i) roaming agreementsthat the wireless operator is a party to with other wireless operators, ii) the user's roaming plan, iii) the radio access technology (RAT) capabilities of the wireless device and iv) the RAT capabilities of other wireless operators in particular geographic regions.

Description

technical field [0001] The described embodiments relate to a server hosted in a home wireless carrier network that provides a list of preferred wireless carriers for access by wireless devices. The wireless device uses the list in a different geographic area than the home network's geographic area. Background technique [0002] Users can perform activities including downloading and uploading data and / or completing voice calls. For example, this activity may be performed using a radio device (also referred to as a wireless device) that conducts transactions with a radio network via radio signals. A radio network may also be referred to herein as a wireless network. The format, timing, information-carrying capacity and multi-user media sharing properties of the radio signal are the result of the particular radio access technology (RAT) adopted by the wireless device and the radio network. A RAT may also be referred to as a radio interface. A problem arises when a user is a...
