| 20090089431 | System and method for managing resources in access network - Disclosed are a system and a method for improved collection of resource information of an access network. The method includes obtaining line information about a line that a subscriber terminal in an access network accesses and resource information about at least a part of the line when an internet protocol (IP) is assigned to the subscriber terminal, transmitting the line information and the resource information from the access network, and creating a database containing the line information and the resource information. Thereby system load is reduced and efficiency of resource allocation is enhanced. | 04-02-2009 |
| 20090133088 | Method and system for IPTV service authentication and service quality control - Provided are a method of and system for controlling IPTV service authentication and traffic flow in an access network. The IPTV service system comprises: a subscriber concentrator which delivers an IPTV service request message that is sent from a subscriber terminal, receives an IPTV service authentication reply message generated in accordance with IGMP in response to the IPTV service request message, and sends a corresponding IPTV multicast stream to the subscriber terminal according to an IPTV service authentication result; a network connector which receives the IPTV service request message delivered from the subscriber concentrator, generates an IPTV service authentication request message in accordance with a RADIUS protocol, sends the generated IPTV service authentication request message to an IPTV service authentication/billing server, generates an IPTV service authentication reply message in accordance with the IGMP when receiving an IPTV service authentication reply message generated in accordance with the RADIUS protocol, and sends the generated IPTV service authentication reply message to the subscriber concentrator; and the IPTV service authentication/billing server which determines whether the subscriber is authorized for an IPTV service when receiving the IPTV service authentication request message that is generated in accordance with the RADIUS protocol and sent from the network connector, and generates the IPTV service authentication reply message in accordance with the RADIUS protocol and sends the IPTV service authentication reply message to the network connector. Accordingly, resources of the access network can be used effectively. | 05-21-2009 |
| 20110002220 | TUNNELING-BASED MOBILITY SUPPORT EQUIPMENT AND METHOD - A tunneling-based mobility support method and apparatus is provided which supports a mobility of a mobile node in a heterogeneous network regardless of IP versions (IPv4/IPv6). The mobility support apparatus includes a load balancer, a plurality of mobility support servers, and a plurality of end routers each being TCP connected to each of the mobility support servers. When receiving a tunnel establishment request message from the mobile node, the load balancer selects one mobility supports server from a plurality of mobility support servers to control a mobility service for the mobile node. The selected mobility support server selects a plurality of tunnel end addresses of one end router from the plurality of end routers to establish an IP tunnel with the mobile node according to a predetermined criterion, forwards the tunnel establishment request message to the end router, and sends the mobile node a tunnel establishment response message including the tunnel end address of the selected end router. | 01-06-2011 |
