    • Provided is a method and apparatus for allocating a multicast connection identifier (MCID) for Internet protocol (IP) packet transmission over a portable Internet network and transmitting packets using the MCID. More specifically, there is provided a method of defining and allocating an MCID for transmitting an IP version 6 (IPv6) multicast packet over an IEEE 802.16/Wireless Broadband (WiBro) network and a process for transmitting an IP multicast packet of a base station (BS) using the MCID. The method of allocating is related to a method of automatically generating a connection identifier (CID) having 16 bits for packet transmission over the IEEE 802.16/WiBro network in order to transmit the IPv6 multicast packet. In this method, a scope value of the IPv6 multicast packet is added to the MCID. Therefore, multicast packets having an effective IPv6 scope such as a multicast packet in a link-local category, a multicast packet in a site-local category, and a multicast packet in a global category can be transmitted over the IEEE 802.16/WiBro network according to the scope of the multicast packet. Accordingly, when a new IPv6 scope is defined, the method can be naturally applied.
    • 提供了一种用于通过便携式因特网网络分配用于因特网协议(IP)分组传输的多播连接标识符(MCID)并且使用MCID发送分组的方法和装置。 更具体地,提供了一种定义和分配用于通过IEEE 802.16 /无线宽带(WiBro)网络发送IP版本6(IPv6)多播分组的MCID和用于发送基站的IP多播分组的过程的方法, BS)使用MCID。 分配方法涉及一种自动生成具有16位的连接标识符(CID)的方法,用于通过IEEE 802.16 / WiBro网络进行分组传输,以便发送IPv6组播分组。 在该方法中,将IPv6组播数据包的范围值添加到MCID。 因此,可以通过IEEE 802.16 / WiBro网络通过IEEE 802.16 / WiBro网络传输具有链路本地类别中的多播分组,站点本地类别中的多播分组和多播分组的有效IPv6范围的多播分组, 到组播数据包的范围。 因此,当定义新的IPv6范围时,可以自然地应用该方法。

    • Provided is a base station (BS) and method of avoiding a flood of join messages for an Internet protocol (IP) multicast group in a portable Internet network, and more particularly, to a BS and method of transmitting join messages for an Internet IP multicast group to an access router or other BSs with a predetermined delay time in an IP multicast (IP version 4 (IPv4) or IP version 6 (IPv6)) service in an IEEE 802.16/Wireless Broadband (WiBro) network. In addition, the BS immediately transmits the join message for the group to other user terminals which belong to the BS. Accordingly, a problem whereby a method of avoiding a flood of multicast group join messages cannot be applied due to point-to-multipoint characteristics of the portable Internet network such as the IEEE 802.16/WiBro network is solved. In addition, the method of avoiding a flood of join messages can be applied using both IPv4 multicast and IPv6 multicast services.
    • 提供了一种在便携式因特网中避免用于因特网协议(IP)多播组的连接消息的洪泛的基站(BS)和方法,更具体地,涉及一种用于为因特网IP多播发送加入消息的BS和方法 在IEEE 802.16 /无线宽带(WiBro)网络中的IP组播(IP版本4(IPv4)或IP版本6(IPv6))服务中具有预定延迟时间的接入路由器或其他BS。 此外,BS立即将该组的加入消息发送到属于BS的其他用户终端。 因此,解决了由于诸如IEEE 802.16 / WiBro网络的便携式因特网的点对多点特性而避免洪泛的多播组加入消息的方法的问题。 此外,可以使用IPv4组播和IPv6组播服务来应用避免大量连接消息的方法。
