Abstract: The IGMP, especially a method for processing the abnormal multicast service and a system thereof, the method for processing the abnormal multicast service includes: when the message carrying the leave multicast group information of a user terminal/user port is lost, for avoiding abnormal condition caused by the losing, the network equipment finds out the multicast group which the user terminal/user port does not belong to and stops forwarding the traffic of the multicast group to the user terminal/user port. By using the present invention, the multicast protocol stack is not modified, and the serious problem caused by IGMP Leave message losing is solved by the redefined multicast process flow based on the present multicast CAC process mechanism and the standard IGMP protocol. By using this method in the application of IPTV and so on, some problem are solved such as packet losing caused by IGMP Leave message losing, channel switching is unsuccessful, the line bandwidth waste affects the other service, the home network bandwidth is wasted, etc.

Abstract: A guaranteed Quality of Service (QoS) method comprises: step A, when a service terminal initiates a service with QoS request, it applies to a application server to establish a connection, and the application server applies to an access network resource management equipment to occupy resource based on the resource that the current service needs; step B, the access network resource management equipment determines the link that the current service needs from the user access equipment to the BAS, and based on the records of the resource of each link, decides whether each of the link that the current service needs has enough available resource, if so, a connection is established, and if not, the current service is refused. Meanwhile, there are a resource management device and a access system. The guaranteed Quality of Service (QoS) method, a resource management device and a accessing system for multi-services that the invention provided, realize a constringency ratio and guarantee the QoS of multi-services by requiring the link and resource that the accessing service will pass through, and allowing the accessing of the service in case of the link resource is available.

Abstract: A method for the user terminal to obtain the access position information, and a user terminal, and a server with dynamic host configuration function, extending the DHCP, adding the new DHCP options which contain the access position information of the user terminal; when the user terminal accesses the network, DHCP server sets the DHCP options in the DHCP answer message; the user terminal receives the DHCP options, and obtains the access position information from it. In prior art, when terminal moves or roams to another access network, it needs to manually change the access network information in the terminal, and it needs to do more work, and it is not flexible, but the scheme provided by the present invention can overcome the aforementioned drawbacks, and make the user terminal obtain the own access position information automatically, and support the moving or roaming for terminal.

Abstract: A method and system for implementing DHCP address security allocation and authentication server. The core of the invention is that DHCP client end send the discovery message through access network; when the access network side acquires the identification information such as the port information of said DHCP client end and the like, and authenticates it based on said identification information; finally, DHCP server only allocates the address information for the authorized DHCP client end. Therefore, the invention may perform accessing authentication for user according to the location information, and only allocates the address for the legal user terminals, thereby it enhances the security for allocating address through DHCP manner. Also, in the invention, the address is managed unifiable by the AAA server, or allocates the address after the AAA server authenticates successfully.

Abstract: A method for implementing the integrated service access in the broadband access network includes: firstly, in the broadband access network, at least one Label Switching Path LSP is created based on the Muli-Protocol Label Switching MPLS; then, in the broadband access node equipment, the traffic to be transmitted is encapsulated with MPLS and transmitted in the broadband access network via LSP. By using MPLS as the broadband access network creating and the private means for passing through the core network, the present invention could nicely solve the confronting problems as using the broadband access network as integrated service bearing network and implement the integrated service bearing of the IP video, voice, data, private line (including IP private line and conventional Asynchronous Transfer Mode ATM private line, Time Division Multiplexing TDM private line, Frame Relay FR private line) with low cost, because MPLS is a technology that provides multi-layer connection.
