20090113068 | Content delivery system, cache server, and cache control server - In a cache control assuming plural user terminals accessing identical content, cache delete priority assignment is performed from a position where a user finished playback based on whether the user intends to view the content later. A cache control server is provided, and a cache delete inhibit span is determined based on a playback stop position or a normal speed playback time. A cache server deletes the cache based on the delete inhibit span received from the cache control server. Traffic of the core network due to re-cache can thus be reduced. | 04-30-2009 |
20090144811 | CONTENT DELIVERY SYSTEM - The selection of video content to be delivered to a video reproducing terminal is enabled from a communication terminal with WEB function without exposing a user ID. When a terminal makes a transfer request of content data, a web server requests a delivery management server for a transfer ID. The delivery management server issues the transfer ID each time the request is made and transmits it to the web server. The web server transmits the content data to a delivery server. The delivery server stores the content data from the web server correspondingly to the transfer ID. When receiving a delivery request including a transfer ID inputted to a video reproducing terminal from the video reproducing terminal, the delivery server reads the content data corresponding to the received transfer ID, and transmits it to the video reproducing terminal. | 06-04-2009 |
20100034209 | COMMUNICATION SYSTEM AND HOME GATEWAY - Even when a site of the Internet is used, switching is automatically performed to a connection via NGN, and a service via the NGN is provided to a user terminal. A HGW transmits a request from the user terminal in accordance with a destination address to a redirect server and a service provider server through one of an IP network and an NGN network. The redirect server redirects access to the service provider server via the IP network to access via the NGN network. The user terminal accesses one of communication devices of the service provider server through the IP network, and communication with the service provider server is performed through the NGN network based on address information of a redirect destination from the redirect server. | 02-11-2010 |
20100050274 | CONTENT CONTROL SYSTEM - A content control system capable of controlling delivery destinations of user contents in respective groups, identifying each group through which each content is delivered, and delivering information/advertisements according to the attribution information of the content. In a content control server, group identifying information is set in each user content to be uploaded to or downloaded from a group memory area corresponding to a gateway ID from a terminal through a gateway having a plurality of its subordinate terminals. The information identifies each gateway through which each object content is delivered according to the gateway ID. The control system controls the delivery destination of each content according to the combination of the content delivery route and a table prepared in the content control server. | 02-25-2010 |
20100064182 | COMMUNICATION SYSTEM - One of network classifications or line classifications is selected and used for one network function. A line classification selection server stores network function information including one or both of communication quality information of a network and billing information for each of network classifications of plural networks. The selection server receives a service start request from a service provider. The selection server refers to the network function information based on the network condition information included in the request, and selects a network classification satisfying the communication quality condition and/or the billing condition. The selection server transmits a server start request including service classification information and identification information of a user terminal to a 3PCC server of the selected network classification. The 3PCC server receives the request, and performs communication control for providing a communication service of the service classification information to designated user terminal. | 03-11-2010 |
20100115565 | CONTENT AND CM DELIVERY SYSTEM AND CONTENT INFORMATION SERVER - In a content delivery system comprising a content information server, a content delivery server, and a terminal information server all located within a communications carrier network, the content information server obtains location information of a content requesting terminal from the location information server and generates a play list per terminal for inserting local CM content into main stream content depending on the terminal location. The content delivery server delivers the main stream content and the local CM content to the requesting terminal according to content identifiers specified in time sequential based on the play list per terminal by the content information server. | 05-06-2010 |
20100149988 | TRANSPORT CONTROL SERVER, NETWORK SYSTEM AND AGGREGATED PATH SETTING METHOD - A transport control server, a network system, and an aggregated path setting method for avoiding congestion on the bypass destination route when an aggregated path consisting of a group of paths was bypassed (diverted) to a bypass destination route. Edge nodes measure the traffic information flowing along each path and notify the transport control server. The transport control server calculates the available capacity of bypass destination routes for each aggregated path based on this traffic information. After receiving a path add request, the transport control server assigns additional paths to the aggregated path so that the aggregated path traffic band that was assigned additional paths, does not exceed the available capacity on the bypass path. The transport control server sends an aggregated path set message to the edge nodes. The edge node complies with the aggregated path set message received from the transport control server and sets the aggregated path. | 06-17-2010 |
20100157898 | COMMUNICATION SYSTEM AND GATEWAY APPARATUS - To control the communication quality on the terminal basis without making the base station more complicated, it is provided a communication system, comprising at least one computer and a gateway that is connected to the at least one computer through a first network. The gateway is connected to at least one terminal through a second network. The at least one terminal performs communications with the at least one computer via the gateway. The gateway estimates quality of the communications between the gateway and the at least one computer in the first network; and determines a priority for the communications between the gateway and the at least one terminal in the second network according to the estimated quality of the communications in the first network. | 06-24-2010 |
20110029654 | Service Control Device, Service Control System, and Method - A communication entrepreneur has an application server | 02-03-2011 |
20110038253 | TRANSPORT CONTROL SERVER, TRANSPORT CONTROL SYSTEM, AND BACKUP PATH SETTING METHOD - A transport control server (TCS) identifies a backup path B switched over to from an active path A due to a path change or a fault, based on information in a path change notification or a fault notification. The TCS identifies a backup path C affected by the switchover from the active path to the backup path. The TCS identifies nodes in which a setting change to delete the backup path C is needed and nodes in which a backup path D should be set up as an alternative to the backup path C and transmits a setting change notification to these nodes. | 02-17-2011 |

20140355426 | TRANSPORT CONTROL SERVER, TRANSPORT CONTROL SYSTEM, AND BACKUP PATH SETTING METHOD - Transport control server (TCS) in a network system including a first backup path (FBP) with predetermined first bandwidth (PFB) secured or reserved between any node pair, second backup path (SBP) with predetermined second bandwidth (PSB) secured or reserved between any node pair, the FBP and SBP sharing a link, each node forwards data according to path setting information. The TCS including: a storage section storing, for each path, an identifier for each node through which the path passes; and a control processing section performing: upon switchover of first active path to FBP, judging whether PSB of SBP can be secured or reserved by the bandwidth of the shared link through which the FBP passes, by referring to the storage section; if not, identifying nodes through which the SBP passes, by referring to the storage section; and transmitting a setting change notification to delete the SBP to the identified nodes. | 12-04-2014 |
