Abstract

PURPOSE: A method of supplying a voice call service between personal portable terminals through a communication network is provided to enable voice calls between the personal portable terminals or between a personal portable terminal and a computer, so as to easily make a voice call while moving. CONSTITUTION: In the steps "S21-S23", personal portable terminals connect to a voice call service providing server through a communication network. If the terminals perform member registration, a web server of the voice call service providing server receives member information including member IDs of each member. The voice call service providing server allows ID addresses corresponding to the members' portable terminals matched with member IDs. The web server stores the member information and the ID addresses in a DB through a DB server. In the steps "S24-S26", the web server interacts with a voice call service manager and the DB server to retrieve a user IP address requested by a member from the DB, and supplies the retrieved IP address.

As a technical means for achieving the above object of the present invention, the method of the present invention is connected to the voice call service providing server through a communication network, and when registering, member information including ID from each member, the voice call service providing server After receiving the web server of the server, the voice call service providing server assigns the IP address corresponding to the terminal carried by each member matching the ID given to each member, and the member information and the IP address are assigned to the DB server. A first step of storing in the DB through; After the load-in, the web server interlocks with the voice call service managing means and the DB server to search for and provide an IP address of the requested user of the member in the DB; Characterized by including.

Hereinafter, a method for providing a voice call service between personal mobile terminals through a communication network according to the present invention will be described in detail with reference to the accompanying drawings. In the drawings referred to in the present invention, components having substantially the same configuration and function will use the same reference numerals.

1 is a configuration diagram of a system for providing a voice call service between personal mobile terminals for carrying out the present invention. Referring to FIG. 1, a system for providing a voice call service between personal mobile terminals for carrying out the present invention includes a voice call function. And a plurality of personal portable terminals 10, such as a personal digital assistant (PDA) or a laptop, which can be connected to the Internet 20, and the user from the personal portable terminal 10 through the Internet 20 It includes a voice call service providing server 30 for requesting a user IP address, in response to the search for the IP address of the requested user in a pre-stored DB and then providing the requested IP address to the requesting user.

The voice call service providing server 30 includes a web server 31 which performs an interface function between the personal mobile terminal 10 and the voice call service providing server 30 through the Internet 20, and the web server 31. And a DB server 32 for storing and managing the member's information and related IP addresses, a DB 32a for storing the information under the control of the DB server 32, and the web server 31. And the corresponding individual who requested the information through the Internet 20 by searching for the user's IP address in the DB 32a based on the user's ID in response to the user's IP address request by the member in conjunction with the DB server 32. Voice telephone service management means 33 provided to the mobile terminal (10).

2 is a flowchart illustrating a method for providing a voice call service between personal mobile terminals for carrying out the present invention, and FIG. 3 is a flowchart illustrating a process of performing the addressing service of FIG. 2.

Operation according to the present invention configured as described above will be described in detail below based on the accompanying drawings.

The present invention provides a user's IP address at the request of a member so as to perform a voice call between a personal portable terminal such as a personal digital assistant (PDA) having a voice call function or between a personal portable terminal and a computer. With a personal mobile terminal, you can easily and cheaply perform voice calls on the go.

Referring to the present invention with reference to Figures 1 to 3, first, in the first step (S21-S23) when the user accesses the voice call service providing server 30 through the communication network 20, the Internet 20 The web server 31 of the voice call service providing server 30 is provided with a start page including a dialogue sign-up window in which the user can register as a member, and in this member sign-up window, a voice call with member information is desired. In addition, the web server 31 is linked with the DB server 32 to store the member information in the DB (32a) to join as a member.

Subsequently, at the time of membership registration, in order to provide the requested voice call service, the voice call service providing server 30 is then matched to an ID given to each member, and gives an IP address corresponding to the portable terminal of each member, The web server 31 stores the member information and the IP address in the DB 32a via the DB server 32.
