Abstract: A resource allocation method of a subscriber station in a service negotiation system is provided. The resource allocation method includes gathering statistics of bursty data, bandwidth grant situation, and measuring wireless signal quality. The subscriber station switches its operation mode according to the statistics and bandwidth data derived by the signal measurement. When the subscriber station in a wireless system switches into a normal operation mode, it allocates bandwidth to management message and numbers of data connections to satisfy the quality of service (QoS) of each connection. When the subscriber station in a wireless system switches into an emergency operation mode, it allocates bandwidth to management message and unsolicited grant service (UGS).

Abstract: The preset invention provides an Intrnet-based automatic security system and method. The security system includes a network server with a database, a network detection module and an automatic transmitting module, and a security device with a microcontroller, a virtual IP network module and wireless transmission module. The network detection module receives the information of security device and detects the networking state. The automatic transmitting module automatically transmits the alarm information from the network detection module to the client and security operator. The microcontroller links security components. The virtual IP network module employs a virtual IP address and links to a virtual IP router through a transmission interface. The security device also contains a polling module automatically linked to the network server for reading data.
