Abstract: A well cementing method is described for improving cementing quality by controlling the hydration heat of cement slurry. By controlling the degree and/or rate of hydration heat release from cement slurry, the method improves the hydration heat release during formation of cement with curing of cement slurry, improves the binding quality between the cement and the interfaces, and in turn improves the cementing quality at the open hole section and/or the overlap section. The cementing method improves cementing quality of oil and gas wells and reduces the risk of annular pressure.

Abstract: The present invention provides a content locating method and a content delivery network node. In this case, the content locating method provided by the present invention comprises: receiving by a first content delivery network CDN node a service request sent by a service control function entity or an IPTV service control function entity, wherein this service request carries a content identifier which is used to indicate requesting content corresponding to this content identifier; if the first CDN node cannot provide the content service requested by the service request, then the first CDN node sends an inquiry request to a CDN global controller so as to acquire the information about a second CDN node which can provide the content service requested by the service request and request the second CDN node to provide the content service. By way of the present invention, the pressure of the CDN global controller can be reduced and the processing delay of CDN can be shortened.

Abstract: The present invention provides an interactive IPTV system and a content pushing method thereof. Wherein, the method includes the following steps: the IPTV Service Control Functions requests to transmit the media content in the IPTV Media Functions to the user equipment; the IPTV Media Functions transmits the media content to the user equipment; and the user equipment stores the media content into its own memory. With the technical solution of the invention, it implements the content pushing service in the Next Generation Network, and makes the user able to select the content stored in the user equipment directly to watch the TV program that the service provider recommends.

Abstract: The present invention provides a method, device and system for pushing information based on Internet Protocol Television (IPTV). In this method, the IPTV serving control functions initiatively send a session initiation request of broadcasting information to the user equipment. After receiving the session initiation request, the user equipment determines to accept broadcasting the information, interacts with the transport processing functions, joins the multicast channel of the information, and receives the multicast stream sent by transport processing functions to broadcast the information.

Abstract: The present invention discloses a distributing method for a file content of an interactive network television system, including the following steps: a content preparation function module transmitting a distributing request of a file content to a content distribution and position control function module; the content distribution and position control function module producing a distributing task based on a distributing strategy after it receives the distributing request of the content preparation function module; after selecting the content delivery and storage function module, the content distribution and position control function module forwarding the file content distributing request from the content preparation function module to the content delivery and storage function module; and based on the response of the content delivery and storage function module transmitted by the content distribution and position control function module, the content preparation function module transmits the file content to the co

Abstract: The present invention discloses file content distribution method, device and system, wherein, the method includes: a content preparing means selecting one or more content location and distribution global controlling means, and sending a file content distributing requests to the selected content location and distribution global controlling means; after receiving the file content distributing request, the content location and distribution global controlling means selecting one or more content delivery and storage controlling means according to a predetermined distributing strategy, and transmitting the file content distributing requests to the selected content delivery and storage controlling means; after receiving the file content distributing request, the content delivery and storage controlling means selecting one or more content delivering and storing means according to the predetermined distributing strategy, and transmitting the file content distributing request to the selected content delivering and stor

Abstract: The present invention discloses a content delivery device and system, content-on-demand method and network architecture, wherein, the content delivery device is used to realize content delivery function in next generation network, wherein, the next generation network includes a transmission stratum which includes a transmission function entity and a service stratum which includes a service control function entity. The content delivery device is located in the service stratum on top of the transmission stratum, is connected between the service control function entity and the transmission function entity, and is used to deliver the content from application functions module of next generation network to a terminal user. In virtue of the technical scheme of the present invention, various service systems such as IPTV can be merged in next generation network, various multimedia services of next generation network are developed expediently and the vacancy of the related technology is filled up.
