When the phone 12 is to establish a connection with the access point 11, the user has to use the phone 12 to enter a character code 22 consisting of several alphanumeric characters. The phone 12 then transmits the character code 22 to the access point 11. Finally, the access point 11 compares the default character code 21 with the character code 22 entered by the user to determine whether to establish the connection with the phone 12.
Generally speaking, a phone 12 has the number keys 0-9. Using a phone 12 to enter the numerals in the character code 22 is relatively easy. The user simply presses the number keys thereon. However, to enter non-numeric characters in the character code 22 using a phone 12 is inconvenient. This is because a non-numeric character is selected via a combination of number keys and a specific input method. This increases the time required for entering the character code 22.
Therefore, it is very useful to provide an easier input method for the VOIP system to establish the connection between a phone and an access point.
In view of the foregoing, the invention is to provide a VOIP system that allows the user to enter exclusively numerals on a phone to establish the connection between the phone and an access point.
To achieve the above, the invention discloses a VOIP system cooperating with a phone and an access point, which stores default connecting information. The VOIP system includes a transmitting module, a receiving module, a decoding module and a comparing module. The transmitting module is disposed in the phone and transmits numeral information. The receiving module is disposed in the access point and receives the numeral information. The decoding module is disposed in the access point and is electrically connected with the receiving module for converting the numeral information into character information. The comparing module is disposed in the access point and is electrically connected with the decoding module for comparing the character information and the default connecting information so as to determine whether the access point proceeds to connect with the phone or not.
As mentioned above, the VOIP system of the invention converts numeral information into character information and compares the character information with the default connecting information so as to determine whether the access point proceeds to connect with the phone or not. In other words, the user only needs to enter the numeral information using the phone in order to establish the connection between the phone and the access point. This avoids the difficulty of entering alphabetic characters using a phone.
The invention will become more fully understood from the detailed description given herein below illustration only, and thus is not limitative of the present invention, and wherein:
The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

The VOIP system 4 includes a receiving module 412, a decoding module 413, and a comparing module 414 disposed in the access point 41 and a transmitting module 421 disposed in the phone 42.
The transmitting module 421 in the phone 42 transmits numeral information 52. In practice, the numeral information 52 can contain information such as network verification or encryption passwords. In this embodiment, the network verification can be a service set identifier (SSID), and the encryption password can be a wired equivalent privacy (WEP). Moreover, the phone 42 further includes an input module 422 electrically connected with the transmitting module 421. In this case, the user can enter the numeral information 52 into the phone 42 via the input module 422 and send the numeral information 52 to the transmitting module 421. Generally speaking, the input module 422 may include a numeral keypad or a set of numeral buttons.
The receiving module 412 in the access point 41 receives the numeral information 52. The decoding module 413 is electrically connected with the receiving module 412 and converts the numeral information 52 into character information 53. The character information 53 consists of at least one alphabetic character and at least one numeral to represent the network verification or encryption password corresponding to the numeral information 52. In this embodiment, the character information is in accord with the American Standard Code for Information Interchange (ASCII).
The comparing module 414 is electrically connected with the decoding module 413 and the memory module 411, and compares the character information 53 with the default connecting information 51 for the access point 41 to determine whether to establish a connection with the phone 42. The default connecting information 51 consists of at least one alphabetic character and at least one numeral, and may include a network verification or encryption password for the connection according to needs. In this embodiment, the comparing module 414 compares the character information 53 with the default connecting information 51 and generates a comparison result accordingly. If the comparison result indicates that the character information 53 is the same as the default connecting information 51, the access point 41 and the phone 42 can establish a connection.
According to the current embodiment, the information transmission between the transmitting module 421 in the phone 42 and the receiving module 412 in the access point 41 can be wired or wireless.

In accord with the current embodiment, the VOIP system 4 can further include an encrypting module 423 and a decrypting module 416 for the actual network information transmission security. The encrypting module 423 is disposed in the phone 42 and electrically connected with the transmitting module 421. The decrypting module 416 is disposed in the access point 41 and electrically connected with the receiving module 412. The encrypting module 423 receives the numeral information 52 from the input module 422, encrypts the numeral information 52, and transfers it to the transmitting module 421. The decrypting module 416 receives the numeral information 52 from the receiving module 412, decrypts the numeral information 52, and transmits it to the decoding module 413. This mechanism can increase the security of information transmission between the phone 42 and the access point 41.
In summary, the VOIP system of the invention converts numeral information into character information and compares the character information with the default connecting information so as to determine whether the access point proceeds to connect with the phone or not. In other words, the user only needs to enter the numeral information using the phone in order to establish the connection between the phone and the access point. This avoids the difficulty of entering alphabetic characters using a phone.
