When the wireless communication device can access the Internet wirelessly, even if the user does not currently use the wireless service, the wireless communication device will continue to receive encapsulated data from the remote server, and then wake up the dormant processor to process the encapsulated data. The above-mentioned mechanism for the processor to go into sleep can reduce the power consumption of the wireless communication device, which is a common power saving method for the wireless communication device at present.

However, attacks by network hackers emerge in endlessly. In addition to the above-mentioned service package data, wireless communication devices more often receive malicious attack package data, such as scanning communication port (port) package data. Such encapsulated packet data is not the data the user wants, but it will cause the processor to be woken up frequently and shorten the sleep time of the processor, making the above power saving method ineffective. Even if the user does not operate the wireless communication device, the processor Maintaining the operating state instead of the dormant state for a long time causes the wireless communication device to consume unnecessary power.

Detailed ways

Referring to FIG. 1, FIG. 1 is an implementation block diagram of a wireless communication device according to the present invention. In FIG. 1 , a wireless communication device 1 includes a data processor 11 , a modem processor 12 , a memory 13 and an antenna 17 . The memory 13 is used to store digital data, such as an application program 131 and an operating system 132 that can be executed by the data processor 11 , as well as data generated by the data processor 11 . The antenna 17 receives the radio wave 142 from the base station 141 in the wireless network system 14 and converts the radio wave 142 into an analog signal including the encapsulated data 121 . The modem processor 12 is electrically connected to the wireless network system 14 through the antenna 17 for receiving the encapsulated data 121 from the base station 141 or transmitting the encapsulated data 121 to the base station 141 through the antenna 17 . Wherein, the wireless network system 14 is preferably a WIFI system, a GPRS system or a 3G system or other network systems capable of wirelessly transmitting encapsulated packets.

The data processor 11 executes the operating system 132 to provide an execution environment for the application program 131 . When the application program 131 is executed, it can connect to the remote server 16 through the wireless network system 14 to perform network services. For example, the application program 131 can be a real-time information (IM) program. Friends exchange real-time information.

When the preset condition occurs, the data processor 11 generates network information 133 corresponding to the application program 131 , and the modem processor 12 filters the encapsulated packet data 121 according to the network information 133 . Wherein, the preset condition may be that the data processor 11 is about to enter a sleep state. For example, when the timer 111 in the data processor 11 counts the time during which the data processor 11 has not received an operation instruction for more than the preset time, it means that the user has not operated the wireless communication device 1 within the preset time, and The wireless communication device 1 will not be operated for a short period of time, so the data processor 11 can enter a sleep state to reduce power consumption of the data processor 11 . Before entering the dormant state, the data processor 11 stores the network information 133 related to the currently executing application program in the memory 13, for example, the operating system detects the currently used communication port 134, or the remote communication port currently communicating with the application program. The network address 135 of the server 16. Afterwards, the modem processor 12 filters the received encapsulated packet data 121 according to the network information 133 , and decides whether to wake up the sleeping data processor 11 according to the filtering result.

Referring to FIG. 2 , FIG. 2 is a representation diagram of an embodiment of network information according to the present invention. This embodiment records nine groups of application-related communication ports 134 and network addresses 135 . Although the user has not operated the wireless communication device 1 for a long time, since the user has not closed the application program, the user may expect that the application program should maintain the connection with the remote server 16 for continued use when the wireless communication device 1 is operated again. Therefore, when the data processor 11 enters the sleep state to reduce power consumption, if the modem processor 12 receives the encapsulated data 121 , it will wake up the data processor 11 to process the encapsulated data 121 .

Because some encapsulation packet data is the encapsulation packet data that hacker sends or virus program sends, for example requires the encapsulation packet data of scanning communication port, and modem processor 12 receives the number of times of this type of encapsulation packet data quite frequently, if every time The data processor 11 needs to be woken up after receiving the encapsulated packet data 121 , and the number of wakeups will be greatly increased due to such hackers encapsulating the packet data, which will shorten the sleep time of the data processor 11 and reduce the power saving effect. Therefore, the modem processor 12 of the present invention filters the encapsulated packet data 121 according to the network information 133, if the destination communication port in the encapsulated packet data 121 matches the data recorded in the network information 133, for example, the destination communication port is 2578, which means that this is the encapsulated packet data sent to the second application program, so the modem processor 12 can wake up the data processor 11 to execute the second application program to process the encapsulated packet data. For another example, if the source address in the encapsulated packet data 121 matches the data recorded in the network information 133, it means that this was sent by the server that exchanged information with the application program 131 before, and it needs to be processed by the data processor 11, so the modem The call processor 12 wakes up the data processor 11 to process the encapsulated data to make an appropriate response to maintain the online relationship with the server. If the destination communication port and source address in the received encapsulated data do not match the network information 133 , the modem processor 12 does not wake up the data processor 11 .

Referring to FIG. 3 , FIG. 3 is an implementation flowchart of the encapsulation packet filtering method according to the present invention. In practice, the encapsulated packet filtering method is used in a wireless communication device, the wireless communication device includes a modem processor and a data processor, and the modem processor is used to receive at least one encapsulated packet data and the data processor is used to execute an application program . In FIG. 3 , it is first judged in step S31 whether a preset condition occurs. If the preset condition occurs, then in step S32, the network information related to the application program is generated, such as the communication port used by the application program or the network address of the received encapsulated data. In step S33, the modem processor filters the received encapsulated packet data according to the network information.

Wherein, the above-mentioned network information for filtering encapsulated packet data may be automatically generated by the wireless communication device, but it is not limited thereto, and part of the network information may also be manually set by the user if necessary.

Referring to FIG. 4 , FIG. 4 is an implementation flowchart of the power saving method according to the present invention. In FIG. 4 , the process is illustrated by implementing the power saving method on the wireless communication device 1 in FIG. 1 as an example. First, in step S41, it is judged whether the accumulated number of the timer 111 exceeds the preset threshold value. If so, it means that the user has not operated the wireless communication device 1 for a long time, so the data processor 11 can prepare to enter the sleep mode to save power consumption. If the accumulated number of the timer 111 exceeds the preset threshold value, then in step S42, the operating system 132 detects and records the communication ports 134 currently used by all application programs 131, and then records the remote server 16 communicating with it by the application program 131 The network address of 135. In step S43, the data processor 11 is controlled to enter the sleep mode. In step S44, the modem processor 12 receives the encapsulated packet data, and then in step S45, the modem processor 12 judges whether the received encapsulated packet data conforms to the recorded communication port 134 or the network address 135, if not, Then step S44 is executed. If so, the data processor 11 is woken up in step S46 to process the encapsulated packet data.

i) The sleep time of the data processor can be effectively extended to reduce the power consumption of the wireless communication device.

ii) The network information used for filtering can be automatically generated by the wireless communication device, so as to improve user's operation convenience.
