The invention provides a method for accessing a mobile core network by utilizing a fixed network (comprising a WLAN access network and a broadband IP exchange network) to obtain business service, comprising the following steps: a soft terminal obtains a user identity and authentication information; the soft terminal sends a registering request message I to a core network access gateway through a fixed network access layer and the IP exchange network, and the registering request message I carries the user identity and the authentication information; the core network access gateway sends a registering request message II to the mobile core network, and the registering request message II carries the user identity and the authentication information; the mobile core network echoes an authentication request message II containing authentication parameters II to the core network access gateway; and the core network access gateway echoes an authentication request message I containing authentication parameters to the soft terminal through the fixed access layer and the IP exchange network. By using a mobile user identification card (including an SIM card, a UIM card and a USIM card and the like) through a universal interface, the invention can realize businesses of mobile network voice, short message, data and the like simultaneously in a fixed broadband IP network, and has great advantage compared with other schemes which only realize business of the voice or the data singly.

Methods for modifying a switching table of an Internet Protocol (IP) switch. The methods include: receiving a dynamic host configuration protocol (DHCP) option 43 request from a host of a LAN at an access port of the IP switch; transmitting the request to a DHCP server; intercepting a DHCP response for the request from the DHCP server; extracting an IP address from the intercepted DHCP response; and adding the extracted IP address to a corresponding entry (specific to the access port) of a switching table of the IP switch. The methods include: receiving an IP frame at an access port of the IP switch; reading an IP source address from the IP frame; and in the switching table either: creating a new entry including the IP source address and its associated port identifier or changing an existing entry based on the IP source address and the access port.

Method for processing content of an Internet Protocol (IP) packet and method for processing a full broadcast IP packet. Processing content of an IP packet includes: extracting IP source and destination addresses and payload from the IP packet; and generating an IP frame encapsulating the IP source and destination addresses and the payload between a preamble field and an error checking field. Processing a full broadcast IP packet includes: receiving the full broadcast IP packet including an IP source address and a full broadcast IP destination address; ascertaining a closest matching IP address and a subnet thereof in a switching table of an IP switch; replacing the full broadcast IP destination address in the IP packet with a subnetted source address generated by applying the subnet mask to the IP source address; transmitting the IP packet to all IP addresses in the switching table within the subnetted source address.

Internet Protocol (IP) switch and method for switching an IP frame to an IP destination address. The IP switch includes access ports, interswitch ports, and a switching table. Each access port is connected to a corresponding host in a LAN. The interswitch ports are configured to be statically connected to routers within the Internet in connections that cannot be overwritten by dynamic learning. The switching table includes entries, each entry having an IP address, a port identifier, and a routing protocol internal metric indicative of confidence in the entry. The method for switching the IP frame includes: receiving the IP frame, reading the IP destination address from the IP frame, ascertaining a matching IP address in the switching table that matches the IP destination address, directing the IP frame to a specific port, transmitting the IP frame from the specific port to the IP destination address.
