Abstract: A system and method of ring back notification for the EP phone is provided. A caller and a receiver communicate in the IP network through the respective connected nodes. When the receiver's network is busy, a request message is sent to the server of the IP network. The server receives the request message of starting a ring back notification and sets a ring back notification tag. Afterwards, the network status of the receiver is detected recurrently. Once the receiver's network is detected to be idle, the ring back notification is sent to the server and then to the caller's node. The function of the ring back notification is to notify the caller that the receiver's network is idle after the receiver's busy status is over, so that the caller can communicate with the receiver in time.

Abstract: A computer peripheral device wireless linking method and system is proposed, which is designed for use in conjunction with a wireless peripheral device and a computer platform for the wireless peripheral device to be linkable via an access-point device to the computer platform; and which is characterized by the use of a wireless LAN searching and linking technology for the wireless peripheral device to be linked via the access-point device to the computer platform without having to use Ethernet ports, input devices, and monitor screens as in the case of prior art. This feature allows the wireless peripheral device to be linked to the computer platform with an instant play capability, such that the use of the wireless peripheral device is more convenient.
