Detailed ways

In the following, the system operation of the present invention will be described first by referring to FIG. 1A , an architecture diagram of the Internet phone system for providing portable phone numbers provided by the present invention. As shown in the figure, the system of the present invention includes a network phone 110 , a first authentication host 121 , a second authentication host 122 , and a call initiation protocol server 130 . Wherein the network phone 110 is coupled with the memory card 111, responsible for reading out the account data in the memory card 111, and when the memory card 111 is successfully verified by the first authentication host 121, it receives the verification data sent by the first authentication host 121, and After receiving the verification data sent by the first authentication host 121, send the read account data and received verification data to the call initiation protocol server 130; Afterwards, verify the memory card 111, and when the verification is successful, generate verification data corresponding to the memory card 111 and send it to the network phone 110 and the second authentication host 122; the second authentication host 122 is responsible for storing the verification sent by the first authentication host 121 data, and when the call initiation protocol server 130 intends to verify the verification data sent by the Internet phone 110, read out the verification data stored corresponding to the memory card 111 for verification; the call initiation protocol server 130 is responsible for receiving the verification data sent by the Internet phone 111 After receiving the account data and verification data, verify whether the received verification data is correct through the second authentication host 122, and register the network phone 110 with the received account data when the verification data is correct.

Then an embodiment is used to illustrate the operating system and method of the present invention. The memory card 111 mentioned in this embodiment is an example of a Subscriber Identity Module (SIM), but not limited to a Subscriber Identity Module; FIG. 2A is a flow chart of the method for using an Internet phone for providing a portable phone number according to the present invention. As shown in the figure, the user who uses the present invention first inserts the customer identification card 111 storing the account data into the network phone 110, so that the network phone is coupled with the customer identification card (step 210), wherein the customer identification card stored The account data includes the user's phone number (MobileStation Integrated Services Digital Network; Mobile Station ISDN; MSISDN) of [13292414]. Then the network phone 110 will verify the customer identification card through the first authentication host 121 (step 220). The method of verification is for example: The identification code of the customer identification card is sent by the Internet phone 110 to the first authentication host 121. After the first authentication host 121 receives the identification code of the customer identification card, it will generate a calculation data and send it to the Internet phone 110. The Internet phone 110 receives After receiving the calculation data sent by the first authentication host 121, the verification formula on the customer identification card will be read out, and the calculation data will be calculated according to the verification formula, and a first calculation result will be generated after the calculation, and the network phone 110 will calculate the The first calculation result is sent to the first authentication host 121. While the network phone 110 is calculating the first calculation result, the first authentication host 121 will also search its database for the verification formula corresponding to the identification code it receives, and The generated calculation data is calculated according to the searched calculation formula, and the second calculation result is generated after the calculation. When the first authentication host 121 receives the first calculation result sent back by the network phone 110, the first authentication host 121 combines the first and The second calculation result is compared, and when the two are the same, the verification of the customer identification card coupled to the Internet phone 110 is successful, but the method of verifying the customer identification card is not limited to the above method. After the client identification card verification is successful, the first authentication host 121 will generate a verification data (step 231), and send the verification data to the network phone 110, and also read the identification code corresponding to the client identification card from the database The user phone number [13292414], and the verification data and the user phone number are sent to the second authentication host 122 (step 232). The verification data generated in this embodiment is the password used by the user to log in and use the Internet phone. But it is not limited to this, and for security considerations, the verification data generated by the first authentication host 121 can also be temporary, which means that the first authentication host 121 generates a different password each time for the user to log in once. Once the user has logged in, it cannot be used again. After the second authentication host 122 receives the verification data and the user's phone number from the first authentication host 121, the verification data will be stored in the password field corresponding to the user's phone number [13292414] (step 240); and the network phone 110 After receiving the verification data (step 251) from the first authentication host 121, the Internet phone 110 will read the account data on the customer identification card (step 252), such as the user's telephone number, etc., and based on the read The account data and the verification data received from the first authentication host 121 generate registration information, wherein the generated registration information includes the user's phone number, network location, verification data and so on. After the registration information is generated, the Internet phone 110 will send the registration information to the call initiation protocol server 130 (step 260). The authenticating host 122 verifies whether the verification data is correct (step 270). The verification method is as follows: the call initiation protocol server 130 transmits the user's phone number and the verification data to the second authenticating host 122, and the second authenticating host 122 bases the received user's phone number on Read out the verification data stored by step 240, compare the verification data received and the verification data read out, when the two verification data are the same, the verification data sent by the SIP server 130 is correct, so the second authentication host 122 Will respond to the call initiation protocol server 130 to verify the correct signal, and the call initiation protocol server 130 will register the Internet phone 110 according to the user's phone number and network location in the registration information after receiving the verified correct signal (step 280) , so that the network phone 110 can make a call with the user's user phone number, but the method of verifying whether the verification data is correct is not limited to the above, and the call initiation protocol server 130 can also request the second authentication host to correspond to the received user The verification data of the phone number is compared by the call initiation protocol server 130, and the Internet phone 110 is registered when the two verification data are the same. When the user wants to leave, he only needs to pull out the customer identification card from the Internet phone 110, and the Internet phone 110 will lose the user's account data, which can protect the security of the account data. When the user moves to another new location, such as a branch office, he only needs to insert his customer identification card into the network phone of the branch office, and the network phone of the branch office will repeat the above-mentioned registration process, so that the call initiation protocol server 130 knows the network location of the subscriber phone number representing the user at this time, when other users dial in, the call initiation protocol server 130 will send the control signal to the correct network location; and when the user wants to dial to other users When the person, because the user phone number on the Internet phone of the branch company is the user's usual use, so the caller's user phone number displayed by the receiver is the user's usual user phone number, so, The present invention can solve the problem that [number portability] cannot be truly achieved.

In the above-mentioned process, since the second authentication host 122 receives and stores the verification data (step 340) and the network phone 110 receives the verification data (step 351) can be carried out simultaneously, so the order of execution can be replaced arbitrarily; and the network phone 110 receives the verification data The data (step 351) and the network phone 110 reading the account data (step 352) have no sequence relationship, and the sequence can also be replaced arbitrarily.

In addition, as shown in FIG. 1B, the first authentication host 121 and the second authentication host 122 of the present invention can be integrated into the same authentication server 120, so in the above-mentioned steps, send or receive to the first authentication host 121, the second authentication server 120 The data of the host computer 122 will be transmitted or received by the authentication server 120 instead. The detailed steps are as shown in FIG. 320), when the authentication server 120 verifies the memory card 111 successfully, it will produce verification data corresponding to the account data of the memory card 111 (step 331), and send the verification data generated to the network phone 110 (step 332) and store the verification data (step 340), after the network phone 110 receives the verification data from the verification server 120 (step 351), it will send the account data read out from the memory card 111 and the verification data received from the verification server 120 to the call initiation protocol Server 130 (step 352, step 360), after the call initiation protocol server 130 receives the account data and verification data transmitted by Internet phone 110, it will verify whether the verification data received by authentication server 120 is correct (step 370), when When the verification is correct, the VoIP will be registered according to the received account data (step 380). Equally, since sending verification data (step 332) has no sequential relationship with storing verification data (step 340), the order of carrying out can be replaced arbitrarily; receiving verification data (step 351) and reading account data (step 352) have no Sequential relationship, the order of carrying out can also be replaced arbitrarily.

In addition, the method for using an Internet phone for providing a portable telephone number of the present invention can be implemented in hardware, software, or a combination of hardware and software, and can also be implemented in a computer system in a centralized manner or distributed in several interconnections with different components. A decentralized implementation of computer systems.
