Description

Network selection method and device, electronic equipment and chip system Technical Field The disclosure relates to the technical field of wireless communication, and in particular relates to a network selection method, a network selection device, electronic equipment and a chip system. Background Along with the development of wireless communication technology, multi-card wireless terminals (such as multi-card smart phones and internet of things terminals) are increasingly used as the multi-network access requirements can be met. However, due to product form design or cost control limitation, radio frequency resources (such as radio frequency transceivers and baseband processing units) of most terminals cannot support parallel network selection of a plurality of communication entities (such as SIM cards), serial network selection mode is required, and how to realize ordered scheduling and efficiency optimization of multi-card network selection under limited resources becomes a problem to be solved urgently in industry. In the related art, the conflict of multi-card network selection resources is usually solved through multi-card resource arbitration, namely, network selection resources are allocated according to preset priorities, network selection tasks of communication entities with highest priorities are executed first, network selection tasks of other communication entities are suspended, and the network selection tasks are executed in sequence after the network selection resources are released. But when the currently selected communication entity searches for a cell that does not meet its own camping conditions but is adapted to other suspended communication entities, the information is directly discarded. When the network selection task of other communication entities is executed later, full-frequency searching is needed again, so that the searched proper cell resources cannot be reused, the multi-card network residence time is prolonged, the network selection resource conflict is continuously aggravated, and the network selection efficiency is reduced.
