[Embodiment] ◎ [0007] As shown in Fig. 1, it is an operational environment diagram of a preferred embodiment of the modulation demodulator of the present invention. The electronic device 2 is connected to other electronic devices by means of the modem 1, the network 3, for example, the network device 4, the mobile phone 5, the computer 6, and the like. The electronic device 2 may be a mobile phone, a computer, a personal digital assistant, or the like. It is an object of the present invention to cause power consumption of the electronic device 2 by reducing the reception of malicious packets. The modem 1 can be built in the electronic device 2 or externally connected to the electronic device 2. For example, when the electronic device 2 is a mobile phone, the modem 1 can be built in the mobile phone, when the electronic device 2 098143814 form number A0101 page 5 / total 20 pages 0982075044-0 [0008] 201123773 [0012] [0012] [0014] [0016] [0016] When the computer is a computer, the modem can be externally connected to the computer. The electronic device 2 may include an Internet Protocol (11) system 20, a processor 22, and other components and application software not shown in FIG. 1, such as a memory, an operating system, and the like. The network 3 can be an Internet or other types of communication networks. As shown in Fig. 2, it is a functional block diagram of a preferred embodiment of the modem of the present invention. In the preferred embodiment, the modem 丨 includes a processor 10 and a storage device 12, wherein the processor 1 is configured to perform each of the 调 modulators 1 installed or embedded in the modulating demodulator 1 The storage device 12 described by the soft 髅β is used for storing various types of materials, for example, a blacklist 12 〇, a white list 12.2, etc. for recording Ι 位 address nicknames, various types of associations, and the like. In the preferred embodiment, the modulation demodulator further includes a set module 14, a timer 15, a packet buffer 16, and a judging module 17. The selection module 14 is configured to preset a period of time to control the electronic device 2 to enter a sleep state. The data of the blacklist 120 and the whitelist 122 may be set, modified, added, deleted, etc. by using the setting module 14, or may be set and modified by the IP system 20 in the electronic device 2. , add, delete, etc. The timer 15 is configured to start timing after the modulation demodulator 1 is started. The packet filter 16 is configured to receive a packet 098143814 at the modulation demodulator 1 Form No. A0] 01 Page 6 / Total 20 Page 0992075044-0 201123773 [0017] Ο [0018] [0019] ❹ [ 0020] [0021] It is judged whether the IP address or nickname of the packet is transmitted in the blacklist ΐ2〇 or the whitelist 122. If the IP address or nickname of the packet is sent in the tidy list 120, then the packet filter 16 discards the received packet. If the IP address or nickname of the packet is sent in the whitelist 122, then The packet filter 16 causes the timer 15 to clear the timing and restarts the timing, and transmits the received packet to the electronic device 2. The determining module 17 is configured to determine whether the preset time period has arrived. If the preset time period arrives, the electronic device 2 enters a sleep state to save power. .... . . . . . . . . . . . . . . . . The packet filter 16 is further configured to clear the timer 15 and restart the timing when the electric hand device 2 transmits the packet via the network 3. In other embodiments, the modem 丨 further includes an identification module U. If the IP address or nickname of the packet is not present in the blacklist 12# and the whitelist 122, the identification module 18 identifies whether the received packet is a malicious packet according to a preset identification criterion. If it is a malicious packet, the packet filter 16 discards the packet, and the setting module 14 stores the IP address or nickname of the malicious packet in the blacklist 120; if the packet is not malicious, the packet The filter 16 clears the timer 15 and restarts the timing, and transmits the packet to the electronic device 2. The identification standard can be customized according to user requirements. For example, if a packet is continuously sent in a short time to request to establish a connection, but no other data packet is transmitted after the connection is established, it may be regarded as If the packet is sent maliciously, the identification module 18 may add the bee 098143814 form number A0101 7th buy/total 20 pages 0982075044-0 201123773 to the blacklist 120. [0022] The present invention is primarily directed to discarding a malicious packet when the modem 1 receives a malicious packet, i.e., does not transmit the malicious packet to the electronic device 2 for processing. For example, if the modem 1 is in a dormant state, the modem 1 receives a malicious packet and directly discards the malicious packet, the electronic device 2 still maintains a sleep state, thereby achieving power saving. . [0023] The mention of the electronic device 2 into a sleep state as mentioned in various embodiments of the present invention does not conflict with other standby and sleep settings in the electronic device 2. For example, in the embodiments of the present invention, if the electronic device 2 enters a sleep state, and then the user performs related operations (for example, inputting information) on the electronic device 2, the electronic device 2 can be made to sleep. The status changes to the working status. 3-1 and 3-2 are flowcharts showing a first embodiment of the power saving method of the present invention. The flowchart of this first embodiment is directed to a flow for realizing power saving according to the reception of the packet by the modulation demodulator 1. [0025] In step S2, the storage device 12 in the modem 1 stores in advance a configuration file such as a blacklist 120 and a white list 122 for recording IP addresses, nicknames, various types of agreements, and the like. [0026] Step S4, the setting module 14 presets a time period to control the electronic device 2 to enter a sleep state. [0027] Step S6, the timer 15 starts counting after the modulation demodulator 1 is started. 098143814 Form No. A0101 Page 8 / Total 20 Page 0992075044-0 201123773 [0028] [0031] [0033] [0033] [0035] [0036] [0036] Step Lion, said The packet is over-received 16_ The modulation solution receives any packet by the network 3^&s the modulation demodulator 4 receives the shame packet, the flow proceeds to the step if the modulation demodulator is old The network 3 receives the packet, and in the step (4), the packet filtering Hl6_ sends the packet's ιρ address or nickname in the whitelist 122. If the IP address I of the packet is sent in the white list 122 in step S12, the packet buffer 16 sends the received packet to the electronic device 2, and the city order (4) 15 is cleared. The flow returns to step S6 to cause the timer 15 to restart timing. If the IP address or nickname of the packet is not present in the whitelist 122, the packet filter 16 described in step S14' determines whether the ι ρ address or nickname of the packet is present in the blacklist 120. If the IP address or nickname of the packet is sent in the blacklist 120, the packet filter 16 discards the received packet in step S16, and the flow proceeds to step S22. If the IP address or nickname of the packet is sent, it does not exist in the blacklist 120. In step S18, the identification module 18 identifies whether the received packet is a malicious packet according to a preset identification criterion. If the received packet is not maliciously packetized, the flow returns to step S12. If the received packet is a malicious packet, the packet filter 16 discards the packet in step S20, and the setting module 14 will send the evil 098143814 form number A0101 page 9 / total 20 pages 0982075044-0 201123773 The IP address or nickname of the intended packet is stored in the blacklist 120. [0037] Step S2 2, the determining module 17 determines whether the preset time period has arrived. If the preset time period arrives, in step S24, the determining module 17 causes the electronic device 2 to enter a sleep state to save power. If the preset time period has not yet arrived, the flow returns to step S8. [0038] As shown in FIG. 4, it is a flow chart of a second embodiment of the power saving method of the present invention. The flowchart of this second embodiment is directed to a flow for realizing power saving by transmitting a packet according to the modulation demodulator 1. [0039] Step S30, the timer 15 starts timing after the modulation demodulator 1 is started. [0040] Step S32, the packet filter 16 determines whether the modem 1 sends any packet through the network 3. [0041] If the modem 1 transmits a packet by the network, the packet filter 16 clears the timer 15 in step S34, and then the flow returns to step S30 to cause the timer. 15 restart the timing. [0042] Step S36, the determining module 17 determines whether the preset time period has arrived. If the preset time period arrives, in step S38, the determining module 17 causes the electronic device 2 to enter a sleep state to save power. If the preset time period has not yet arrived, the flow returns to step S32. [0043] In summary, the present invention complies with the requirements of the invention patent, and submits a patent application according to law.
