Abstract
An apparatus, method, and system for filtering an Internet Protocol (IP) packet in a mobile communication terminal are provided. The method includes receiving an IP packet from a network, determining whether the received IP packet is an IP packet unallowable by an application Central Processing Unit (CPU), and when the received IP packet is determined to be an IP packet unallowable by the application CPU, generating an IP packet indicating that the received IP packet is unallowable and transmitting the generated IP packet to the network.

17. A method comprising:
-
receiving, at a first electronic device including a first processor and a second processor, using the first processor, a message from a second electronic device via a communication channel established between the first electronic device and the second electronic device; determining, using the first processor, a first determination that the message corresponds to at least one of a first set of one or more port numbers designated as unallowable by the second processor, or a second determination that the message does not correspond to any one of a second set of port numbers designated as allowable by the second processor; and releasing, using the first processor, one or more resources associated with the communication channel based on the first determination or the second determination. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)

26. An apparatus comprising:
-
a first processor to establish a communication channel between the apparatus and an electronic device external to the apparatus; and a second processor to transmit one or more port numbers to the first processor, wherein the first processor is configured to receive a message transmitted from the electronic device via the communication channel, to determine a first determination that the message corresponds to at least one of a first set of one or more port numbers designated as unallowable by the second processor, or a second determination that the message does not correspond to any one of a second set of port numbers designated as allowable by the second processor, and to release one or more resources associated with the communication channel based on the first determination or the second determination. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)

35. A modem comprising:
a processor to establish a communication channel across a network between the modem and an electronic device external to the modem, the processor configured to; receive a message transmitted from the electronic device via the communication channel; determine a first determination that the message corresponds to at least one of a first set of one or more port numbers designated as unallowable by another processor external to the modem, or a second determination that the message does not correspond to any one of a second set of one or more port numbers designated as allowable by the other processor; and release one or more resources associated with the communication channel based on the first determination or the second determination. - View Dependent Claims (36)
