摘要
A subscriber identification module (SIM) level task scheduler is described. A dual SIM device SIM radio controller determines quality of service (QoS) levels for each service running on a dual SIM device. A first SIM and radio are connected to one of an unlicensed spectrum network or a licensed spectrum network, which are operated by a same service provider. A second SIM and radio scan for available network connections operated by the service provider. The dual SIM device measures QoS levels and the controller checks them against QoS requirements. The controller instructs the second radio to connect to a selected network from the available networks when the measured QoS levels are at least steadily degrading. The dual SIM device shares and negotiates the first radio settings with the selected network. The controller instructs a processor to switch from the first to the second radio when the selected network is ready.
