Abstract:
PURPOSE: An AUTOSAR meta file based basic software attribute value inspecting device is provided to verify setup of attribute values of an electronic device software platform by verifying a basic software attribute value based on an AUTOSAR meta file. CONSTITUTION: A meta file defining unit(101) defines a meta file attribute value of an AUTOSAR(Automobile open system architecture) meta file. A basic software setting unit(102) sets up an attribute value of a basic software setting file. A basic software attribute value checking unit(103) compares the basic software attribute value with an AUTOSAR standard by using the meta file attribute value.
Abstract:
PURPOSE: A vehicle network setting method based on AUTOSAR(AUTomotive Open System Architecture) and an apparatus thereof are provided to enable an electronic field application developer to easily set up a vehicle network model. CONSTITUTION: A screen unit receives a structure setting input value from outside. If a user selects an ECU(Electronic Control Unit) and a communication cluster from the screen unit, a structure setting unit(100) displays the ECU and the communication cluster on a communication channel and sets up a network architecture based on the communications channel. A data setting unit(200) sets up data based on the communication channel.
Abstract:
PURPOSE: A hierarchical monitoring method of a vehicle is provided to perform the routing of information in a routing technique in consideration of the property of a moving vehicle. CONSTITUTION: A plurality of nodes shares information about communication channels(S10). If a first node is selected, a plurality of sub groups is formed(S30). A second node is selected at each sub group(S40). The second node collects status information from the plurality of nodes. The first node collects the status information. The first node transmits the status information to the service agent of a first sub network(S50). The service agent transmits an ACK(Acknowledgement) message to the first node(S60). The second node transfers the response message to a corresponding node(S70).

Abstract:
A mobile router management system in a PMIP 6(Proxy Mobile IPv6) domain and a method thereof are provided to make a PMIP6 support the communication of a node belonging to a mobile network in case the PMIP6 domain is used as the home network of a mobile router. A profile server(406) registers the profile information of a plurality of mobile nodes(for example, mobile routers(400)) connected to a PMIP6 domain. In case the mobile node is a mobile terminal, the profile server registers profile information including the home prefix of the mobile terminal. In case the mobile node is a mobile router, the profile server registers profile information including the home prefix of the mobile router and mobile network prefix information. MAG1 to MAG3 and an LMA(404) set up forwarding information for the home prefix of the mobile router which connects to the PMIP6 domain and the mobile network prefix which is managed by the mobile router.
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: A device including a SNMP(Simple Network Management Protocol) function and a communication network management method using the same are provided to manage M2M(Machine to Machine) communication network devices in real time by connecting to a SNMPv2 protocol. CONSTITUTION: A M2M communication network connecting unit compresses a reference SNMP packet(S110). The M2M communication network connection unit transmits the SNMP packet to an M2M communication network device(S120). The M2M communication network connection unit receives the SNMP packet compressed from the M2M communication network device(S130). The M2M communication network connection unit generates the reference SNMP packet by releasing the compression of the SNMP packet(S140). The M2M communication network connection unit transmits the generated reference SNMP packet to an SNMP manager(200)(S150). [Reference numerals] (AA) Start; (BB) End; (S100) Receive a reference SNMP packet from an SNMP manager; (S110) Compress the reference SNMP packet; (S120) Transmit the compressed SNMP packet to an object communication network device; (S130) Receive the compressed SNMP packet from the object communication network device; (S140) Generate the reference SNMP packet; (S150) Transmit the reference SNMP packet to the SNMP manager
