Abstract: A BS(Base Station) apparatus and a method for IP(Internet Protocol) multicast group join message flooding avoidance in a portable Internet network are provided to reflect a temporal gap using a delay timer in the portable Internet network having point-to-multipoint characteristics, thereby preventing excessive distribution of multicast group join messages. A BS(Base Station) apparatus for IP(Internet Protocol) multicast group join message flooding avoidance in a portable Internet network comprises the followings: a receiver(221) for receiving a join message for a group from a first subscribe station(200) which wants to join the IP(Internet Protocol) multicast group; and a transmitter(222) which transmits the received join message for the group to other subscribe station(210,250) which belonging to the BS, and transmits the received join message for the group to an access router(230) to which the BS belongs and other BSs(240) which belong to the access router when the join message for the group is not received from a second subscribe station during a set time after the receiver receives the join message for the group from the first subscribe station.

Abstract: PURPOSE: An IPv6 Internet address automatically generating method and lookup method using a phone number are provided to allow a phone terminal user to easily access the Internet by using a phone number which has been assigned and conveniently used when an IP protocol is mounted at a phone terminal so as to be used as a host for using an Internet service, and obtains an IP address by generating an IP address of the phone terminal on the basis of a phone number so as for the phone terminal to be operated as a transmitter in an IPv6 communication environment. CONSTITUTION: An IPv6 protocol engine reads a phone number of a terminal(S41). Each decimal number is made to 4 bit binary form by using the phone number constructed as an E.164 form(S42). Since the binary bit stream has the maximum 60 bits or below, a padding operation is performed to add '0' to upper bit digits until it becomes 64 bits from the created bit stream(S43). A 64 bit phone number interface ID is combined with prefix information assigned in an IPv6 protocol operation(S44). An automatic generation of an IPv6 unicast address is completed(S45), and an Internet host transmits an IP packet by using the address.
