Abstract: A method and system for power saving in a wireless LAN is disclosed, which uses the method of modifying the beacon frame body or broadcasting the schedule information frame. The medium access behavior of each station during the contention free period (CFP) and the contention period (CP) can be dynamically re-programmed. Therefore, the stations that should access the radio medium can only wake up at the specific access time to send or receive the packet and re-enters its power-saving state after the data transmission.

Abstract: A method and apparatus for controlling multi-mode radio access, more particularly, to a method and apparatus that supports multi-mode reconfigurable, quality of service (QoS) and seamless handoff in different radio systems so as to provide wire-line like QoS guarantee. The apparatus includes a network layer, a radio adaptation layer, a radio system layer and a physical layer. Therein, the radio adaptation layer is used to control the radio modules disposed in the radio system layer to support the QoS needed in the upper layer. The radio adaptation layer is also used to build up, correct and seamlessly change the radio link, and ensures that the packets from the upper layers can be orderly delivered to the lower layer with preset QoS.

Abstract: A method for examining a user's identity and/or administrating the access right(s) of a called function is disclosed. Before the called function is functioned in a computer system, the method redirects the executing procedure to an interception means, which further processes a user's identity verification and/or the access right(s) examination. Next, after confirming the identity and/or the access right(s), the called function is functioned. For example, by modifying the preceding operation codes, the called function can jump to the means for intercepting; a corresponding entry of executable file dynamic library import table is modified; a method for replacing the library with called function to be intercepted is introduced; and a callback function is provided to redirect the executing procedure to an identity verification/access control unit.

Abstract: The present invention discloses a method and system for dynamically specifying and instantly transmitting and representing/displaying call data, wherein a data, which is specified by the caller or the callee dynamically, can be instantly transmitted, and represented/displayed as soon as the data has been transmitted and before the callee answers the call. The instant and dynamic transmitting or represent/display of the specified data can be undertaken before or during the preset outgoing/incoming activity of a call or replaces the preset outgoing/incoming activity of a call, and the specified data can be a picture, an image, a voice, an Internet link, other format of file, or an appropriate combination of the aforesaid data.
