IPC: H04W72/12
Filed: 2007-02-23
Abstract: A shared channel scheduler device in a wireless packet communication system and a shared channel scheduling method using the same are provided to reduce an error rate of the overall transmission packets and improve system throughput by using a signal power-to-noise power ratio. When a call is established(S11), a user ID is received from an upper layer. It is checked whether a user will transmit or receive packet data(S12) and priority level of the user is set(S13). When packet data is received from the upper layer(S14), a service priority level is set(S15). Multi-quality service can be received according to a service provided by a service provider(S16). Data is transmitted by preferentially selecting a user having a good channel environment by using a channel state(C/I) received from the user(S18). Data to be transmitted next is received by a buffer(S19) and a scheduler checks a delay time after receiving the data by the buffer(S21). User throughput about how much data has been transmitted by each user is determined based on the amount of data transmitted form the buffer(S20). A priority level is calculated based on the calculated packet delay and the user throughput(S22). A service operator performs a user scheduling process with respect to the user ID, a service ID, the packet delay and the user throughput calculated from each information(S23) and transmits data(S24).

Filed: 2007-08-16
Abstract: A notification receiving method of an AS(Application Server) using an open service gateway is provided to solve a problem that because an AS simply performs only a client function or only a server function, it cannot perform both functions when necessary. An AS requests notification from an open service gateway(200), and a Web service client module(110) generates a correlator(S101) and registers interface information between the Web service client module and a Web service server module(130) by using the correlator as a key value to a binding DB(120)(S102). The Web service client module generates notification request information including an address of the Web service server module and the correlator, and transmits the same to the open service gateway(S103). If particular conditions of the checked notification are generated(S104), the open service gateway generates information including notification of the generated particular conditions and notification including the correlator. The open service gateway transmits the generated notification information to the Web service server module(S105). The Web service server module recognizes the correlator from the received notification information(S106), and searches the binding DB to check whether there is a Web service client module corresponding to the recognized correlator(S107,S108). If there is no Web service client module information, the Web service server module provides an error message to the open service gateway(S109). If there is Web service client module information, the Web service server module transfers a notification of the open service gateway to the Web service client module of a corresponding ID(S110).
