摘要： A apparatus and method for automatically determining a valid IP configuration on a network analyzes traffic and determines valid subnets. A likely unused start IP address in a subnet is selected and checked to determine its availability. If not available, the start address is decremented, and tested again, until a valid address is obtained

摘要： In a mobile communication network providing an Internet service, the arrived packets are delivered from the nearest neighbor router device to the mobile terminal device according to the need such as when a prescribed application is activated or when a prescribed packer has arrived, by using message exchanges between the nearest neighbor router device and the mobile terminal device, so that it becomes possible to prevent the unnecessary packet attacks from the global Internet.

摘要： In a broadband cable data network (10), a method and system for automatically allocating network resources such as IP addresses to control access to the network utilizes at least one DHCP server (12), and a common network database formed from a LDAP directory (22) for storing respective user configuration parameters, hardware address registration, and current binding information. A DHCP server (12) can add new hardware address registrations to the LDAP using an 'unregistered' service class. The DHCP server sends a DHCP reply tailored for unregistered devices, such as by allocating a privately-allocated IP address with no Internet access, or an IP address for a self-provisioning web server. A DHCP server views IP address allocation as having a short duration. Thus, if the IP network configuration does not change, user terminal will continue to receive the same allocated IP address due to the DHCP server's perception of an indefinite lease. The consistency of the IP addresses simplifies many operational concerns about dynamic addresses, such as minimizing DNS (domain name service) hostname updates, mapping IP addresses to user terminals during security incidents, etc.

摘要： In a data transmission method according to the present invention, a transmission request is forwarded from a host apparatus (4) to a terminal apparatus (2). When receiving the transmission request, the terminal apparatus (2) forwards a communication request to the host apparatus (4). In this communication request, a timer value of a system timer (82) included in the terminal apparatus (2) is incorporated. Having received the communication request including the timer value, the host apparatus (4) establishes an ID for the terminal apparatus (2) according to the timer value. Then, the host apparatus (4) conducts polling for collecting data from the terminal apparatus (2) using the established ID.

摘要： An embodiment of the invention provides a method for Diameter prefix authorization. The method includes sending a request for a prefix by a Prefix Authorization (PA) client or Diameter client to a Prefix Authorization (PA) server or Diameter server. The method also includes replying with an answer message by the PA server to the PA client to provide a first prefix with a first lifetime. An embodiment of the invention further includes a method for initiating IPv6 address renumbering by sending a message for renumbering from the PA server. The method also includes receiving the message by the PA client and sending a message to the PA server to acquire a second prefix. The method further includes receiving the second prefix from the PA server with an answer message with a second lifetime, where the second prefix is different from the first prefix.

摘要： The present invention relates to a method and apparatus for allocating a value of a parameter to a client host by an access point in a communications system comprising an IP network, where the parameter value has previously been assigned to the same client host by a first parameter-value assigning node. The method includes using a DHCP message to carry a signed information package from the first parameter- value-assigning node to the access point via the client host. The signed information package comprises information on a preferred value of the parameter and a signature of the first parameter- value-assigning node. The signature can be verified by the access node, and if true, and if the preferred value is available for allocation, the access node will allocate the preferred value of the parameter to the client host.
