Abstract: The present invention provides an overflow control method for frame synchronization of base stations in wireless communication network system. The wireless communication network system includes a radio network controller, a first base station, a second base station, and a mobile unit. The radio network controller transmits a plurality of data frames to the first base station and the second base station. The present invention includes the following steps. First, determine whether number of the plurality of data frames received by the second base station is larger than a judging storage capacity. Second, calculate an X and delete X of data frames from the second base station if the number is larger. The X is equal to the result of subtracting the judging storage capacity from the number. Meanwhile, detect a link quality between the mobile unit and the first base station. If the link quality is lower than a preset value, calculate an N and delete N of data frames from the second base station when N is larger than zero. The N is equal to number of data frames not yet deleted from the second base station and already received by the mobile unit.

Abstract: This invention provides a method for power-efficient transmission supporting integrated service over WLAN. The said invention combines the polling-based and the contention-based mechanisms, named on-demand polling (ODP). In the ODP scheme, a voice station is in the polling list when it is in the active mode. During the idle mode, it is configured to operate in the sleep mode for saving power. Also, it adopts the contention-based mechanism to join the list again while returning from the idle mode. On the other hand, the data station adopts the contention-based mechanism to transmit its packets over WLAN. In addition, to achieve service differentiation, the said invention also employs a prioritized access probability for voice over data services. Simulation results show that the said invention can reduce the power consumption for voice stations and enhance the throughput for data stations.

Abstract: A method for dynamic division of the radio capacity in a Time Division Multiple Access (TDMA) system between different packet radio services. Each packet radio service is composed of packets with the same or different priority. Several MSs can share a time slot. Information regarding to the interference for each MS is obtained by a request from a mobile station (MS) or through a traffic measurement at the base transceiver station. This information, along with the QoS contract, is used as criteria in allocating more time slots to packet radio service. A framework of dynamic scheduling for mobile communication (DSMC) comprising a Channel Codec Unit (CCU) and a Packet Control Unit (PCU) determines the service rate upon the required QoS of a user and the interference level.
