Please refer to FIG. 1 , the IPv6 network system 100 of the present invention includes a network server 10 , a modem 20 and a host 30 connected to the modem 20 . The modem 20 periodically sends a routing request and a DHCPv6 request at the same time to request the network server 10 to assign a network prefix to the modem 20, so that the host 30 can obtain an IPv6 host address through the assigned network prefix.

In this embodiment, when the network server 10 receives the routing request and the DHCPv6 request sent by the modem 20, it determines whether the host 30 has applied for a predetermined charging service according to the routing request and the DHCPv6 request. When the network server 10 determines that the host computer 30 has applied for a predetermined charging service and that the balance of the account related to the predetermined charging service can meet the minimum consumption of the predetermined charging service, it selects the route notification and the DHCPv6 prefix agent according to the preset agreement. One is to assign a network prefix to the modem 20, so that the host 30 can obtain an IPv6 host address through the network prefix, and under the environment of the IPv6 host address, the host 30 can obtain the service of the platform that provides predetermined charging services. When the network server 10 determines that the host computer 30 has applied for a predetermined charging service and the balance of the account related to the predetermined charging service cannot meet the minimum consumption of the predetermined charging service, it selects two methods of route notification and DHCPv6 prefix proxy according to the preset agreement. The other one assigns a network prefix to the modem 20, so that the host computer 30 obtains an IPv6 host address through the network prefix, and in the environment of the IPv6 host address, the host computer 30 cannot obtain the service of the platform that provides predetermined charging services . In this embodiment, the predetermined charging service is an Internet phone service, and when the network server 10 determines that the host computer 30 has applied for an Internet phone service and the balance of the account related to the Internet phone service can meet the minimum consumption of the Internet phone service, the DHCPv6 prefix is selected. The agent assigns the modem 20 a network prefix. Of course, in other implementation manners, the predetermined charging may also be other types of charging services.

In this embodiment, when the network server 10 determines that the host computer 30 has not applied for a predetermined charging service, the selected network prefix allocation method is the same as the account that the network server 10 determines that the host computer 30 has applied for a predetermined charging service and is related to the predetermined charging service. The network prefix allocation method selected when the balance of the network cannot meet the minimum consumption of the scheduled charging service.

In this embodiment, the network server 10 selects one of route advertisement and DHCPv6 prefix proxy to allocate network prefixes according to whether the host 30 has applied for a predetermined charging service and the balance of the account related to the predetermined charging service, so as to control the host 30 Whether the corresponding services can be obtained. In this way, the network server 10 can control whether the host 30 can obtain the corresponding service by selecting a way of allocating network prefixes.
