    • In a communications network, a home domain of the network formulates a multicast packet destined to a first multicast address locally unique in the home domain, encapsulates the packet in a packet destined to a second multicast address other than an individual care-of address, and transmits the packet. A mobile node visiting a foreign domain receives a packet containing the second multicast address. In a foreign-to-home multicast transmission, the visiting mobile node formulates a multicast packet destined to the first multicast address, encapsulates the packet in a packet destined to the second multicast address and transmits the packet. In the home domain, a packet containing the second multicast address is received and decapsulated to extract a packet destined to the first multicast address. The second multicast address is either a globally unique multicast address or a foreign local multicast address which is locally unique in the foreign domain.

    • The mobile communication network system of the present invention is made up from a mobile communication network (MNW), a plurality of external networks (EX1-EX3), a plurality of mobile terminals (x, y, z), a plurality of gateways (EGW1-EGW3) for connecting the external networks (EX1-EX3) and mobile communication network (MNW), and a plurality of radio access points (APa1-APc2) for connecting the mobile terminals (x, y, z) to the mobile communication network (MNW). When packets are transmitted and received between mobile terminals (x, y, z) within the mobile communication network (MNW), the packets are communicated, not by way of external networks (EX1-EX3), but by way of virtual networks that correspond to each external network (EX1-EX3) that have been prepared on the mobile communication network.

    • An object of the present invention is to provide an access system which can accommodate constant bit rate data irrespective of the traffic conditions and which also allows accommodation of variable bit rate data at a high circuit utilization efficiency. The access system is constructed such that a master station first performs allocation of transmission right for constant bit rate data to all of slave stations for each transmission period for constant bit rate data. The master station does not immediately perform allocation but reserves requests for transmission right for variable bit rate data, and after allocation of transmission right for constant bit rate data to all of the slave stations, the master station allocates the requests for transmission right for variable bit rate data to non-used regions within the transmission period.
    • 本发明的一个目的是提供一种接入系统,其可以容纳恒定的比特率数据,而不管交通状况如何,并且还允许以高电路利用效率调节可变比特率数据。 访问系统被构造成使得主站首先在恒定比特率数据的每个传输周期中向所有的从站分配用于恒定比特率数据的传输权限。 主站不立即执行分配,但保留对可变比特率数据的传输权的请求,并且在向所有从站分配用于恒定比特率数据的传输权之后,主站分配用于可变位的传输权请求 将数据传输到传输周期内的未使用区域。
