A method for assigning an installation task to processor resources of a mobile terminal, the method comprising: acquiring a load amount of the installation task; and characterised by: judging whether or not available processor resources with an operational capability corresponding to the load amount are able to handle the load amount; based on a judgement that the available processor resources are able to handle the load amount, determining those available processor resources as available processor resources for the installation task; based on a judgement that the available processor resources are unable to handle the load amount, querying whether available processor resources with other operational capabilities are able to handle the load amount; if the available processor resources with the other operational capabilities are able to handle the load amount, determining those available processor resources as the available processor resources for the installation task; assigning the installation task to the available processor resources for the installation task for executing when the available processor resources for the installation task are queried; and improving a performance index of the available processor resources for the installation task. acquiring a load amount of the installation task; and characterised by: judging whether or not available processor resources with an operational capability corresponding to the load amount are able to handle the load amount; based on a judgement that the available processor resources are able to handle the load amount, determining those available processor resources as available processor resources for the installation task; based on a judgement that the available processor resources are unable to handle the load amount, querying whether available processor resources with other operational capabilities are able to handle the load amount; if the available processor resources with the other operational capabilities are able to handle the load amount, determining those available processor resources as the available processor resources for the installation task; assigning the installation task to the available processor resources for the installation task for executing when the available processor resources for the installation task are queried; and improving a performance index of the available processor resources for the installation task. judging whether or not available processor resources with an operational capability corresponding to the load amount are able to handle the load amount; based on a judgement that the available processor resources are able to handle the load amount, determining those available processor resources as available processor resources for the installation task; based on a judgement that the available processor resources are unable to handle the load amount, querying whether available processor resources with other operational capabilities are able to handle the load amount; if the available processor resources with the other operational capabilities are able to handle the load amount, determining those available processor resources as the available processor resources for the installation task; assigning the installation task to the available processor resources for the installation task for executing when the available processor resources for the installation task are queried; and improving a performance index of the available processor resources for the installation task.
