Abstract

Handheld wireless communications devices use their home carrier network as long as the handheld remains in a coverage area of that network. When the handheld is no longer in that network, it seeks an alternate carrier network with a partnership agreement with the home carrier network. If there is a choice between two alternate carrier networks, by default, the choice is automatically made based on signal strength. This will not always be the right choice for a user who may be more concerned with selecting the least expensive carrier network or a network that provides the highest level of service (for example, voice and data instead of just voice, or some other qualitative criteria). In addition, handheld communication devices also offer manual network selection, however the only available information for making a selection is the name of the network and possibly signal strength. The other possible selection criteria, such as voice and data roaming costs, are not available. Finally, some handheld communication devices make their selection based on their current geographic location. The solution for voice-only handheld devices is to allow carrier network selection based on cost, level, and/or quality of service. For data-and-voice-capable handheld devices, the partial (voice) versus full (voice and data) differentiation may be used in addition to cost and quality of service. In both cases, the selection can be made automatically (after the user specifies the relative importance of each criteria), or manually (by presenting the user with the additional information when making a manual network selection). Other helpful selection settings may be: to prompt the user whenever they roam (triggering manual selection), to set a maximum cost when selecting by least cost, and to allow the user to disable voice or data functionality of the device whenever roaming onto a network with a relatively high cost. Since the carrier characteristics change over time, the handheld device should have the capability to download cost from roaming partner tables for their home carrier based on the carrier identifier stored on the SIM.
