Abstract: A polling control apparatus includes a scheduler to identify polling applications in an electronic terminal and group together the polling events of the polling applications based on the polling times of the polling applications. A polling application may be in more than one group based on the interval between polling events of the application. A traffic manager of the polling control apparatus manages a data connection between the polling control apparatus and a network to connect the electronic terminal to the network at a polling event start time of the group and maintain the data connection until all polling events in the group are completed. The polling control apparatus may adjust the polling time of applications to be during the data connection or based on an importance parameter of the application.

Abstract: A mobile terminal includes an execution unit to execute tasks, a determination unit to determine whether to manage the executed tasks and to generate a termination processing signal for terminating a first executed tasks if the executed tasks are to be managed, and a control unit to terminate the first executed task according to the termination processing signal generated by the determination unit. A method for managing tasks includes executing tasks, determining whether to manage the executed tasks, generating a termination processing signal for terminating a first executed task according to the determination result, and terminating the first executed task according to the termination processing signal.
