摘要:
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.

Disclosed is a communication method using the mobile IPv6 in the NAT-PT environment, and a recording medium storing the method. An NAT-PT (Network Address Translation—Protocol Translation) box as a substitute for an IPv4 node in the communication method performs an RR (Return Routability) process and a BU (Binding Update) process with an IPv6 node to allow data communication between the IPv4 node and the IPv6 node. Therefore, mobility support using the mobile IPv6 is provided in the network with the mixed IPv4 and IPv6.

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.

The present invention provides a method and apparatus for setting up a gateway for an AUTOSAR-based vehicle network. The apparatus for setting up the gateway includes a candidate selection unit for selecting an Electronic Control Unit (ECU) connected to at least two communication clusters, from among a plurality of ECUs, as a gateway candidate, and a gateway generation unit for generating a gateway instance with reference to the ECU selected by the candidate selection unit, and generating a gateway meta-model including the gateway instance based on instance generation input values entered by a user.

Disclosed herein is an apparatus for evaluating Automobile Open System Architecture (AUTOSAR) meta file-based basic software properties. The apparatus includes a meta file generation unit, a basic software configuration unit, and a basic software property evaluation unit. The meta file generation unit generates the meta file properties of an AUTOSAR meta file. The basic software configuration unit sets the basic software properties of a basic software configuration file. The basic software property evaluation unit evaluates basic software properties using the meta file properties in order to determine whether the basic software properties were set in conformity with an AUTOSAR standard.
