In order to make the above and other objects of the present invention clear, the preferred embodiments are specifically described below. The features, advantages and advantages can be more obvious and in accordance with the accompanying drawings, detailed descriptions are provided to provide a dimension I * b77 @ 、 丄 讯 装置, so as to replace the processing method, which is applicable to A mobile mine and a mussel are present in this example, but it is not used for roaming between routing areas of the PT 1 ΐ hard number router. It can also be used to invent the 'domain domain switching processing method of the present invention. Processor 1. The composition of the 4 ° mobile phone 5 includes I Λ early 2 and memory 3, as shown in Figure 2. 1 ... Fig. 3, although the mobile phone 5 has completed the login to the Internet, the router 10a obtains the dynamic setting for the mobile phone 5. The phone 1 then completes the login to the Internet (step S2). Communication 2 I for network communication. When the mobile phone 5 finishes logging into the Internet S =, (step S2), the processor i starts to execute the domain switching processing method and obtains the porch address of the router in the routing area where the mobile phone 5 is currently located (step S4). The processor stores the lp address in the memory 3 as the first to the IP address. This program can be run as a background program, and when Mobile 5 logs out of the Internet, the processor 1 closes this program. ^ The processor 1 periodically inquires via the communication unit 2 and receives the address information of the router from the router in the routing area where the mobile phone 5 is currently located (step S6). The above-mentioned method for the processor to periodically query and obtain the IP address of the router in the area currently routed by mobile phone 5 is that the "! ^ Mobility Management System (GPRS Mobility Management System) does not actively inform the user whether the user has entered the new routing area. Function to detect the above actions

1220345 V. Description of the invention (6) The method used by phone 5 for roaming. If there is a GPRS action management system that actively informs the user that the new routing area has been entered, the processor 1 does not need to inquire regularly, and only needs to wait for the GPRS action management system to obtain the I of the router in the routing area where the mobile phone 5 is currently located. p address. ^ For example, the processor 1 queries and obtains the IP address of the router in the routing area where the mobile phone 5 destination is located every 3 seconds. The processor 1 compares the currently obtained 1 P address with the previously obtained first IP address (step s 8). If the currently obtained IP address is the same as the previously obtained first IP address, it indicates that it is acting at this time. If the phone 5 does not enter roaming, it returns to step s6, and the processor 1 continues to repeat the action of periodically inquiring and obtaining an IP address. If the currently obtained lp address is different from the previously obtained first IP address, it means that the mobile phone 5 is being diffused "f. At this time, the processor 1 stores the currently obtained IP address in the memory 3 to replace the previously obtained above The IP address is used as the first IP address. (Step 81) When the processor 1 detects that the mobile phone 5 has started roaming, the early = data is being transmitted or received 'and the transmitted or received data is: The user of the telephone 5 orders to transmit or receive: Second, if the communication unit 2 is in the actual communication state, the data transmission of the order is not interrupted. The update procedure for the non-traffic update of the communication unit 2 will be explained later. The sequence is implemented here. During this network period, the data flow of the communication unit 2 is measured to find out whether it is in the above actual communication state. Here, take 3,000 to attack The critical value of Xunzaowu 2 is due to the above communication unit 2 and the network: the data traffic is often between 0685-10261TWF (Nl); IAC030088.TW; Joseph ptd Page 9 1220345 5. Description of the invention (7 ) There is a system message transmission, but its resources The amount of data is less than 3 kilobytes. 丨 U U ftong 702 is transmitting or receiving the data ordered by the user! It must be more than 3 kilobytes. The processor 1 regularly tests the above communication. The data volume of the communication in the early stage 2 changes to obtain the data flow. In this embodiment, the 'processor 1 regularly queries the router via the communication unit 2 and obtains the communication data volume to know the data flow of the communication unit 2's communication at the same time. , Ask and get the IP address of the network gateway device in the routing area where it is currently located (step S1 2). This process can be used to instantly learn the new routing area of the mobile phone. ^ ^ For example, as shown in Figure- As shown, when the mobile phone 5 is performing network communication I from point D to E of the path 70, the processor 1 detects that the mobile phone 5 has started to roam to the routing area 20b. Therefore, the processor i starts to detect Whether the communication ticket 2 is in the actual communication state. When the mobile phone 5 moves from £ point to point g, the communication unit 2 continues to be in the actual communication state. At this time, the processor 1 continuously detects whether the communication unit 2 is in the actual communication state. Communication status while detecting all current The p address of the network gateway device in the routing area. As soon as the power is turned on, 5 has entered the routing area 2c at point F, but the processing fails to get the relevant information. Therefore, the processor is detecting the communication unit 2 Is it necessary to simultaneously detect the IP address of the current gateway device at the same time as the communication status? If the processor 1 obtains the address of the network gateway device 1 first, the processor 1 compares Is the currently obtained IP address of the network gateway device the same as the previously obtained first IP address (step S18). If the currently obtained IP address of the second device is equal to the previously obtained IP address Same, Xiao returns to step:

I? 20345

S12, the processor continues to inquire and obtain the amount of communication data periodically (step 2). If the currently available network idle = P address is different from the first 1? Address previously obtained, the processor i ^ sets the port at this time ϊι has moved Telegram 10 to another routing area. Then go back to step S1 ° 0 to process the 1p address of the network closed-circuit device obtained before iλ ϋ is stored in memory 3 = "ip address (step ΠΠ and continue to inquire regularly and obtain the IP address of 枓 1 and the network gateway device (step S12). When the processor 1 first obtains the information of the communication data amount, the processor 1 will set the data = 1, and the information will be stored in Memory 3, based on previously acquired and currently acquired,

Based on the information of material 1 to calculate the data volume change to obtain the data flow (step S16): Then compare whether the data flow is greater than the above-mentioned critical value, that is, 3 kilobytes (step 20). If the change of the above-mentioned data amount is greater than 3 kilobytes, it means that the above-mentioned communication unit is in the actual communication state, then return to step s12, the processor 1 continues to inquire and obtain the communication data amount and the IP address of the network gateway device regularly. . If the change in the amount of data is less than or equal to 3 kilobytes, it means that the communication unit is not in the actual communication state, the processor 1 starts to execute the network communication update procedure (step S22), so that the mobile phone 5 stops roaming.

In the above network communication update procedure, the processor 1 logs the mobile phone 5 out of the Internet via the communication unit 2; then the processor 1 logs the mobile phone 5 back into the Internet through the communication unit 2 and the mobile phone 5 passes through it The network gateway device in the routing area where the project is located is assigned a new IP address. In this way, without affecting the actual network communication of the user, all the packets that will be sent to the mobile phone 5 corresponding to this new IP address are directly transmitted
