Abstract: A route planning system includes a network server. The network server includes a plurality of road section data, in which each road section data includes a distance and a plurality of average speed rate data corresponding to a plurality of time intervals. The route planning system calculates at least one possible route according to a departure time, a departure point, and a destination point. The possible route includes a plurality of possible road sections from the departure point to the destination point. The route planning system dynamically searches the average speed rate data of the estimated passing time intervals according to the possible road sections and the distances respectively to calculate the travel time of each possible road section and adds them to receive a total travel time of the possible route.

Abstract: The invention discloses a mobile device for monitoring a vehicle path. The mobile device includes a setting module, a satellite-positioning module, a determination module, and an alarm module. The setting module is configured to set a preset route from a starting point to a destination. The satellite-positioning module is configured to receive a satellite-positioning signal. When the mobile device is located in a vehicle, the determination module is configured to determine whether the vehicle is driving along the preset route based on the satellite-positioning signal. When the vehicle deviates from the preset route for a default alarming time, the alarm module is configured to perform an alarm action.

Abstract: A vehicle data processing device and a vehicle data processing method thereof are provided. The vehicle data processing device gets vehicle data items of a vehicle and creates a vehicle data menu according to the vehicle data items. The vehicle data processing device transmits a different inquiry packet to the vehicle according to the vehicle data menu at a query time interval. The vehicle data processing device receives a plurality of reply packets from the vehicle, wherein each of the reply packets corresponds to each of the inquiry packets. The vehicle data processing device analyses the reply packets to generate a plurality of readable vehicle data of the vehicle, and stores the readable vehicle data. The vehicle data processing device supplies the vehicle data menu to user terminals and processes the vehicle data queries from the user terminals to provide the readable vehicle data thereto.

Abstract: QoS router system and method are provided for effectively processing fragmented IP packets transmitted over a network. When receiving a first fragmented IP packet of a set from a flow, a router determines whether to allow the first packet to pass or to drop by according to predefined QoS rules. A pass status is recorded in a record if the packet is allowed to pass. A drop status is recorded in the record if the packet is dropped. When receiving other fragmented IP packet of the same set, the router determines whether to allow the fragmented packet to pass or to drop by according to the previous record. If the record is drop status, the packet is dropped, and if the record is pass status, the packet is allowed to pass when the used bandwidth of the flow does not exceeds a predetermined bandwidth.

Abstract: A system for message dispatching based on group communication. The system comprises a message gateway, receiving a message from a message server, retrieving a header and contents of the message corresponding to a message address, determining whether first field information in the header contents is identical to a group name in the group address book. If so, the priority in a second field information in the header contents is verified, and the message is sent to each recipient in a group according to reception address information and presence states corresponding to the priority using different data reception methods.

Abstract: An email reading system and method of combining multiple electronic mailboxes and a short message, which has at least one Internet mail server, an Internet message gateway and at least one handheld device. The message gateway applies the POP3 protocol for sending a command of processing email to the mail server, checks corresponding electronic mails (emails) in the mailboxes on the at least one mail server in accordance with a predetermined interval and filters the emails in accordance with a predetermined search condition, such that when one or more of the emails meet the search condition, the message gateway sends a short message to the handheld device. Accordingly, the user can send a short message command to the message gateway through the handheld device for accessing or deleting the one or more emails.

Abstract: A method of network address port translation and look-up. In a network address port translation (NAPT) gateway connecting a virtual internal network and an external network, the virtual internal network includes at least a server, and the external network includes at least a host. When an incoming data packet of a data stream is received from the external network, not only are the destination internet protocol (IP) address and port therein translated, but also the source IP address or source port is replaced by an index of a translation data in a NAPT translation table corresponding to the data packet. When an outgoing data packet of the same data stream is received from the internal network, the index drawn from the destination IP address or destination port can be directly mapped to the translation data.

Abstract: System and method used by a gateway for processing fragmented IP packets from a private network are provided. When receiving a first fragmented IP packet of a set, the gateway records information related to the packet in a NAPT table, records the source IP address and the IP identification of the packet, and the index of the NAPT table item in a fragmentation table, and changes the IP identification of the packet as the index of the fragmentation table item corresponding to the packet. When receiving other fragmented packet, the gateway searches the fragmentation table for finding a corresponding fragmentation table item, thereby retrieving the corresponding NAPT item as indicated by NAPT table index, and translating the source IP address into a legal gateway IP address, and changes the IP identification of the packet as the index of the fragmentation table item corresponding to the packet.

Abstract: NAPT gateway system with method for extending the number of connections are disclosed. The gateway is located between a private network and the Internet and has a plurality of NAPT tables. When receiving a packet transmitted from the private network to the Internet, the gateway takes the destination IP address of the packet as a hash key for corresponding to a NAPT table of the NAPT tables via a hash function. An item of the NAPT table that conforms to the packet is determined, and the source IP address and the source port of the packet are translated into the legal address of the NAPT gateway and the index of the item, respectively, based on the item.

Abstract: QoS router system and method are provided for effectively processing fragmented IP packets transmitted over a network. When receiving a first fragmented IP packet of a set from a flow, a router determines whether to allow the first packet to pass or to drop by according to predefined QoS rules. A pass status is recorded in a record if the packet is allowed to pass. A drop status is recorded in the record if the packet is dropped. When receiving other fragmented IP packet of the same set, the router determines whether to allow the fragmented packet to pass or to drop by according to the previous record. If the record is drop status, the packet is dropped, and if the record is pass status, the packet is allowed to pass when the used bandwidth of the flow does not exceeds a predetermined bandwidth.
