摘要： A mobile communication system can implement broadcasting control that generates broadcast information autonomously in a distributed manner, thereby obviating the need for an RNC (Radio Network Controller). Each base station has an IP address and a base station multicast address. Each base station sends its own system information to all base stations using the multicast address. Each base station generates its broadcast information from its own system information and the system information received from other base stations. Thus, it can generate the broadcast information autonomously in a distributed manner without using the RNC.

摘要： The present invention improves receiving quality compared to the prior art even if instantaneous control of transmission power is not executed. A mobile station MS#0 measures signal level received from surrounding base stations and determines to which base stations it is to be connected in order to satisfy a desired downlink receiving quality (step S1). The mobile station MS#0 notifies a radio network control station RNC of the desired based stations to which the mobile station is to be connected (step S2). Upon receiving the notification from the mobile station MS#0, the radio network control station RNC duplicates a downlink transmitted signal for the mobile station MS#0, if any, and transmits it to the selected base stations (step S3). The mobile station MS#0 receives signals transmitted by the base stations (step S4) and synthesizes these signals (step 5), thereby satisfying the desired downlink receiving quality.

摘要： The present invention provides a packet communication system including a mobile host, a home agent, a correspondent host, and a mobility agent, where the mobility agent operates in such a way that when the mobile host is in an active mode and has no need for buffering packets, the mobility agent forwards packets received from the home agent or the correspondent host to the mobile host; and alternatively, in the case when the mobile host is in an active mode, but requires buffering of packets, the mobility agent buffers the packets, and further in the case when the mobile host is in an idle mode, the mobility agent buffers the packet and notifies the mobile host of arrival of the packet, in order to prevent the loss of a packet addressed to a mobile host thus decreasing the traffic and the transmission frequency of Binding Update packets.

摘要： Efficient paging control is achieved in a communication system that selectively provides one of communication services implemented by integrating a plurality of communication systems. Before transmitting a downlink signal to a terminal, a gateway requests each of the communication systems to transmit a paging signal to the terminal. Receiving the paging signals transmitted from the communication systems, the terminal selects a communication system A with the lowest communication cost in accordance with communication cost information contained in the paging signal. The terminal sends a request for connection to the selected communication system A. As a result, the communication system A transmits the downlink signal to the terminal.

摘要： A retransmission control method is provided. In the method, all base stations perform error judgment for a signal sent from a mobile station 1. Then, first and second base stations send results of error judgment to a third base station which is a communication partner of the mobile station 1. The third base station sends NACK for requesting retransmission to the mobile station 1 only when every result of error judgment of the first and second base stations indicates that there is an error.
