Cellular blacklisting techniques

Abstract

Techniques are disclosed relating to a mobile device blacklisting certain wireless cells. The device may refrain from considering blacklisted cells for cell operations such as reselection and handover. The device may blacklist cells that fail selection criteria or system information decoding. In some embodiments, the device is configured to manage inclusion of cells on the blacklist based on whether the cells are part of a home network (e.g., an HPLMN) for the mobile device. The device may delete cells that are part of the home network from the blacklist after an out-of-service event or may refrain from adding cells from the home network to the blacklist after certain failures, for example. In various embodiments the disclosed techniques may avoid blacklisting desirable cells in certain scenarios while still enabling blacklist functionality. This may improve wireless performance and battery life, for example.
