VIO terminal receiving apparatus and its method {Apparatus and method for VoIP terminal receiver}

The present invention relates to a VoIP (Voice over Internet Protocol) terminal receiving apparatus and a method thereof, and more particularly to a VoIP terminal receiving apparatus and method for making it suitable for receiving VoIP using a VoIP card even when the PC power is off. will be.

In general, a LAN (Local Area Network) refers to a private data communication network installed in a limited area. It connects personal computers installed in each department of an enterprise or institution to each other using a data-only cable to share information or communicate with each other. It is to be taken quickly. These LANs are often targeted at dense computers located in the same building, such as all offices in the same building, factories, power plants, schools, and hospitals. In addition, the LAN is always connected to the network, allowing access to information from other computers immediately if necessary.

When building a LAN like this, a LAN card is needed for individual PCs.

Voice over Internet Protocol (VoIP) is also a term for IP telephony technology for a series of facilities that deliver voice information using the Internet Protocol (IP). This means that voice information is sent in digital form within discrete packets, rather than traditional protocols based on circuits such as PSTN, a public switched telephone network. The main advantage of VoIP and Internet telephony technology is that it integrates telephone service by utilizing existing IP network, allowing telephone users to receive long-distance and international phone service in internet and intranet environment with only local call charge.

VoIP uses Cisco Forums, Vocaltec, 3Com, and Net to promote the use of ITU-T H.323, the standard for transporting voice (sound) and video over IP over the public Internet or on an intranet within the enterprise. This was done by efforts by major equipment manufacturers, including Speak. The VoIP Forum also encouraged directory service standards, enabling users to locate other users and enabling the use of touch phone signals for automatic telephone distribution and voicemail.

In addition to the original IP functionality, VoIP uses a real-time protocol (RTP) to support packets arriving in a timely manner. Using public networks, it is currently difficult to guarantee quality of service (QoS). Better service can be achieved by using a private network managed by an independent company or an Internet telephony service provider (ITSP). The technique used by equipment makers, called NetSpeak, to ensure fast packet forwarding is to surf all network gateways connected to the public network and select the fastest route based on the results before establishing a TCP socket connection with the other party. will be.

To use VoIP, companies must install VoIP equipment, such as Cisco's AS5300 access server, at the gateway. The gateway receives voice delivery in packets divided from users in the company and sends it to other parts of the intranet or to the PSTN using the T-1 or E1 interface.

When the PC 10 is terminated by checking the termination routine, the VoIP card 21 To be identified. At this time, the VoIP card 21 continues to receive power from the adapter 22 even after the PC 10 is terminated.

The VoIP card 21 is then switched from the active state to the standby state.

If the user starts the ring and operates the timer at the same time, the user sends a message such as "no caller response" to the caller, and sends a system shutdown message to the main board 11 of the PC 10. Turn off (10). This causes the PC 10 to be powered off using the signal contained in the window termination routine.

6 and 7, a 220 V power cable is first connected to the power supply 14. At this time, the PC 10 is still in a state before being driven.

The adapter 22 in the power supply 14 is supplied with 220V of power and supplies the necessary power to the VoIP card 21.

When the VoIP card 21 detects a call reception signal, the VoIP card 21 causes the power supply 14 to perform a power-on operation.

The power supply 14 on which the power-on operation is performed supplies 5V and 12V power to the main board 11. The main board 11 then operates, and the LAN card also operates.

In addition, VoIP runs by running software so that VoIP services can be connected to network operators.

In addition, the power key 15 is used to directly power on the PC 10 when there is no telephone reception.

As described above, the present invention is to perform the VoIP service properly by using the VoIP card even when the PC power is off.
