  • Publication number: 20030185214
    Abstract: The present invention relates to a scheduling unit in a wireless communication system. For sequentially receiving a plurality of Protocol Data Units (PDUs) in a plurality of communication sessions, accumulate and schedule the plurality of PDUs during a predetermined time frame, and transmit the PDUs based on a maximum power-strength of the wireless communication system. The scheduling unit comprises a time-based scheduler and a power-based scheduler. When the power-based scheduler schedules the PDUs, if the total sum of the required power of the PDUs exceeds the maximum power-strength of the wireless communication system, the power-based scheduler sends back to the time-based scheduler the PDUs whose power amounts to the exceeding of the maximum power-strength of the wireless communication system according to the corresponding priority values of the PDUs, so that the wireless communication system transmits all at a time the remaining PDUs whose total power remains within the maximum power-strength.

  • Publication number: 20030142643
    Abstract: The present invention discloses a method for applying a multi-protocol label switching (MPLS) network in general packet radio service (GPRS). The MPLS network is established by multiple differentiated service (DS) domains. Each DS domain is constructed by multiple label switching routers (LSRs) and label edge routers (LERs). The LER provides at least a service GPRS supporting node (SGSN) connected to a wireless network base station, and a gate GPRS supporting node (GGSN) connected to a packet switching network. At a signalling plane, IP addresses of all SGSNs and GGSNs are utilized to establish all one-to-one pre-created label switching paths (LSPs) in the MPLS network of the GPRS backbone network. At a transmission plane, the pre-created LSP and LSP tunneling transmit packets between SGSN and GGSN.

  • Publication number: 20020041566
    Abstract: The present invention relates to 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. According to the invention, several MSs can share a time slot. Information regarding to the interference for each MS is obtained by means of 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) is also provided, which comprises a Channel Codec Unit (CCU) and a Packet Control Unit (PCU) . The CCU is responsible for the channel coding and radio channel measurement functions, thereby scheduling the priority of packet service.
