Abstract:
PURPOSE: A method for managing service charge collecting account data is provided to manage a charging policy about a service platform and an application service. CONSTITUTION: A service interface providing unit receives determined result from a negotiation with a service platform server from a service platform server(S202). According to the negotiation information, the service interface providing unit receives an application data from the application program which applies the service platform(S203). The service interface providing unit collects charging information about the application data. The service interface providing unit transfers the charging information to the other node(S204).

PURPOSE: A communication node and a communication error process method thereof are provided to rapidly transmit the detected communication failure to the communication node. CONSTITUTION: An environment change sensing unit(112) senses abnormal sign from the sensed environment change. A power sensing unit senses power which is supplied to a communication node. A control signal generating unit transmits a control signal to a storing unit(120) and a transmitting unit(130). The transmitting unit transmits a communication failure notification message to the communication node. A receiving unit(140) receives a communication failure notification message.
Abstract:
A method for supporting the transport network independent IP mobility and a system therefor are provided to support the mobility by upgrading the software of a mobile terminal or introducing a mobility control device without adding the function of existing transport network equipment. Two control tunnels are established between the first mobile terminal(110) and a mobility control device(130). The mobility control device is connected with a service portal(120) or an AAA server(140) so as to be communicated with them, and manages the mapping relation between the home address and care-of address of a mobile terminal. The mobile terminal including the first mobile terminal receives one intrinsic address which is continuously maintained. The care-of address is assigned according to the current position for each interface of the mobile terminal.

본 발명은 IP망에서의 단대단 QoS 보장 방법에 관한 것으로, 보다 상세하게는 IP망의 인입노드에 적용된 QoS 정책이, OSPF 라우팅 프로토콜에 의해서 각 노드로부터 수집된 TED를 바탕으로 CSPF 경로 설정 알고리즘을 이용하여 목적지 노드까지 QoS 정책이 적용될 수 있도록 하는 방법에 관한 것이다. 본 명세서에서 개시하는 IP망에서 단대단 QoS 보장 방법은 (a)IP망의 인입노드에서 목적지 노드로 전송할 트래픽에 설정된 QoS 정보를, OSPF-TE Opaque LSA에 소정의 부 TLV를 추가하여 상기 목적지 노드까지의 전송 경로상의 중간 노드에 전달하는 단계; (b)상기 중간 노드가 상기 부 TLV를 참조하여 자신에게 기 설정되었던 TED를 신규 TED로 갱신하는 단계; (c)상기 중간 노드가 상기 신규 TED에 근거하여, 상기 설정된 QoS 정보가 보장될 수 있는 상기 전송 경로상의 다음 중간 노드를 CSPF 알고리즘을 통해 추출하는 단계; 및 (d)상기 중간 노드가 상기 추출된 다음 중간 노드에 OSPF-TE 확장 LSA Update 메시지와 상기 QoS 정보를 전송하고 상기 다음 중간 노드의 데이터 평면에 로딩시키는 단계를 포함하여 본 발명의 기술적 사상을 구체화하고 본 발명의 목적 및 기술적 과제를 달성한다.

본 발명에 의한 IP 멀티캐스팅 서비스를 위한 랑데뷰 포인트(Rendezvous Point)의 소스 에지 장치와의 패스 설정 방법은 소스(Source)로부터 수신하는 데이터가 멀티캐스팅용인지의 여부에 따라 룩업 수행 여부를 결정하는 단계; 상기 룩업 수행 성공 여부에 따라 데이터 캡슐화를 결정하는 단계; 및 상기 캡슐화된 데이터를 포워딩하는 단계;를 포함하는 것을 특징으로 하며, 소스측 에지 장비로부터 랑데부 포인트까지 패스가 결정될 때까지 제어 평면으로 전달되는 데이터의 양을 크게 감소시키고 대부분의 처리를 데이터 평면에서 처리함으로써 전체 시스템의 안정성을 향상시키는 효과가 있다.
Abstract:
PURPOSE: A method of setting an expanded label switching path in an MPLS(Multi Protocol Label Switching) system is provided to set an expanded label switching path up to an MPLS area from a forwarding engine mounted in a specific port of an ATM exchange, thereby improving a system performance. CONSTITUTION: An MPLS LER(Label Edge Router) sets a label switched path(401). In an MPLS area, a label switched path setup is performed by a label distribution protocol. When the label switched path is set, the MPLS LER decides an operation mode of the set path(402). If the operation mode operates in an ingress mode, the MPLS LER confirms whether a preset subscriber PVC is connected(406). If so, the MPLS LER registers a forwarding entry for an ingress connection(407), and transmits the registered forwarding entry to a forwarding engine(408).
Abstract:
PURPOSE: A method for setting an expansion label switched path in a multi-protocol label switching system that includes Internet protocol packet forwarding engines is provided to set a label switch path and the expansion label switched path in a switching center. CONSTITUTION: The expansion label switched path generated in each Internet protocol packet forwarding engine is connected to multi-protocol label switching areas(LC-ATM_1 - LC-ATM_n) in one of label switched switching centers. The expansion label switched path, which is connected to the multi-protocol label switching areas(LC-ATM_1 - LC-ATM_n) in a certain label switched switching center, is connected a label switched path that is coupled with the certain label switched switching center.
Abstract:
PURPOSE: A method for setting a multicast label exchange path using a multicast label in an MPLS(Multi-Protocol Label Switching) network, is provided to form multicast label information in order to support a multicast for communication between several users in the MPLS network, and thereby set the path. CONSTITUTION: Label edge router(LER_d, LER_e) sends a join message(Join(MTid, Label, ERP)), which includes a multicast group ID(MTid) and an evident reverse path(ERP), to label switching routers(LSR_b, LSR_c), respectively. The router(LSR_c) sends the join message(Join(MTid, Label, ERP)) to the routers(LSR_b). The routers(LSR_b) receives the join message(Join(MTid, Label, ERP)) from each of the routers(LSR_c, LER_d), and then sends the join message(Join(MTid, Label, ERP)) to a label switching router(LSR_a). The router(LSR_a) receives tree root information "abced" from a root of a multicast group, removes information "a" representing itself, and then sends information "bced" to the router(LSR_b). The router(LER_e) receives the tree root information "e", and thereby recognizes that the router(LER_e) itself is an incoming node. The multicast label exchange path is thus set from the router(LSR_a) to the router(LER_e).
