Patent number: 10104193Abstract: In one embodiment, a method of serving media includes receiving a request to serve a cacheable media content to a user equipment at a second media server deployed in a second layer2 access network. The request is received around when the user equipment is handed-off from a first layer2 node in a first layer2 access network to a second layer2 node in the second layer2 access network and when a streaming session of the cacheable media content to the user equipment from a first media server is terminated. The method further includes determining if the cacheable media content is stored in a cache of the second media server, and serving the cacheable media content from the cache of the second media server to the user equipment if the media content is stored in the cache of the second media server.Type: GrantFiled: August 12, 2016Date of Patent: October 16, 2018Assignee: Futurewei Technologies, Inc.Inventors: Sanqi Li, Tao Qian, Houxiao Han, Hongbo Tian, Kui Lin

Publication number: 20170237798Abstract: In one embodiment, a method of serving media includes receiving a delivery log of traffic use after every first time interval for an user equipment. The user equipment is part of a hot billing class of users. The traffic use comprises data usage by the user equipment during communication with a media server in a layer2 access network. A user traffic information computed from the delivery log is transmitted to a billing center. A account status information is received from the billing center. The account status information is received if the user equipment exceeds a user account metric. A session termination information based on the account status information is transmitted.Type: ApplicationFiled: March 3, 2017Publication date: August 17, 2017Inventors: Sanqi Li, Tao Qian, Houxiao Han, Hongbo Tian, Kui Lin

Patent number: 9723096Abstract: In one embodiment, a method of serving media includes receiving a request to serve media content to an user equipment, and receiving caching information regarding the media content. The caching information includes information regarding whether the media content requested by the user equipment is cacheable. A first media server is assigned from a hierarchical set of media servers to serve the user equipment if the media content to be served is cacheable. The hierarchical set of media servers includes a plurality of first type of media servers deployed in a plurality of layer2 (L2) access networks. The user equipment is coupled to the content delivery network through a layer2 access network of the plurality of L2 access networks.Type: GrantFiled: February 16, 2015Date of Patent: August 1, 2017Assignee: Futurewei Technologies, Inc.Inventors: Sanqi Li, Tao Qian, Houxiao Han, Hongbo Tian, Kui Lin
