摘要:
In an exhaust emission control system for an internal combustion engine, a secondary air is selectively introduced into an exhaust passage at a first position upstream of a catalytic converter. A failure detection system utilizes a plurality of temperatures of an exhaust gas for detecting a failure of the exhaust emission control system. A first temperature is derived at a second position between the first position and the catalytic converter when the secondary air is introduced into the exhaust passage at the first position. A second temperature is derived at the second position when no secondary air is introduced into the exhaust passage at the first position. By comparing the first and second temperature, it is detected whether the exhaust emission control system includes a failure. Third and fourth temperatures may also be derived at a third position located inside or downstream of the catalytic converter, which respectively correspond to the first and second temperatures. By comparing a difference between the first and third temperatures and a difference between the second and fourth temperatures, it is detected whether the exhaust emission control system includes a failure.

A method and apparatus for diagnosing a presence or absence of failure in an idle switch installed in an internal combustion engine in which, a throttle valve of an internal combustion engine is associated with the idle switch. The throttle valve installed in the engine is usually displaced to a fully closed while the engine at least once is during each period of continuous operation, a counter is advanced whenever the engine has started and is cleared when receiving an activation signal from the idle switch, if the idle switch functions normally, a count value of the counter reaches zero by the time the engine has stopped. If the idle switch fails, the count value is advanced whenever the engine is operated and no signal from the idle switch is received. When the count value reaches a predetermined value, an alarm informing the failure of the idle switch is produced.

Disclosed is a technique to provide a handover method that can improve the communication efficiency by reducing tunnel overhead between a mobile node and a home agent. When the mobile node (UE) (107) performs handover (HO) from a first access router (104) to a second access router (105) and if the IP versions supported by the networks before and after the HO are different, the UE transmits a first message including an allocation request for a home address of the HO target to the home agent (HA) and a second message including an address allocation request. The HA transmits to the UE, a third message including the home address of the HO target based on the allocation request and transmits to the UE, a fourth message including the home address based on the address allocation request.

A transmitting side UE1 and a receiving side UE2 are both connected to a given E-Node B. The transmitting side UE1 divides a transmission packet addressed to UE2 into a first packet to be transmitted via a route not passing through a given access gateway and a second packet to be transmitted via a route passing through the given access gateway, and the packets are transmitted to the given E-Node B. The E-Node B transmits the first packet to UE2 and also transmits the second packet to the access gateway. The access gateway receives the second packet and transmits it to the E-Node B. The E-Node B receives the second packet transmitted from the access gateway and transmits it to UE2. UE2 receives the first packet and the second packet and synthesizes them to restore the initial packet.

A technique is disclosed, according to which it is possible to efficiently use network resources, to reduce the burden on a control device, and to control the communication between radio terminals by the control device when a transmitting side radio terminal and a receiving side radio terminal are connected to the same radio relay device. According to this technique, when a transmitting side UE1 and a receiving side UE2 are connected to the same E-Node B 103, the transmitting side UE1 divides a transmission packet addressed to UE2 into a first packet to be transmitted via a route not passing through ACGW 105 and a second packet to be transmitted via a route passing through ACGW 105, and the packets are transmitted to E-Node B 103. E-Node B 103 transmits the first packet to UE2 and also transmits the second packet to ACGW 105.

Disclosed is a technique in which, when a plurality of packet routing paths exist, a sender of the packet selects an optimum packet length so as to use network resources effectively. According to the technique, when a plurality of routing paths like a network A (104) and a network B (105) exist for a packet transmitted from a data transmitting apparatus (103) to a data receiving apparatus (102) via a network relay apparatus (101), the network relay apparatus or the data receiving apparatus searches path MTU information of each path, and notifies the data transmitting apparatus of multipath MTU information including each search result. The data transmitting apparatus refers to this multipath MTU information to compare the plurality of paths about their path MTU information to decide a packet length suitable for the packet transmitted to the data receiving apparatus.
