20140207960 | APPARATUS AND METHOD FOR REDUCING TRANSMISSION DELAY OF HTTP PROTOCOL AND PROCESSING LOAD OF HTTP SERVER IN WIRELESS COMMUNICATIONS NETWORK - A method and apparatus for managing and controlling wireless connection of a HyperText Transfer Protocol (HTTP) proxy device in a wireless communication network are provided. The method includes receiving one of information indicating a wireless connection deactivation of an HTTP client performing HTTP communication and information indicating a change in an Internet Protocol (IP) address of the HTTP client from a predetermined node of the wireless communication network; and deactivating a connection with an HTTP server if the received information indicates the wireless connection deactivation of an HTTP client performing the HTTP communication; and maintaining a connection with an HTTP server if the received information indicates the change in the Internet Protocol (IP) address of the HTTP client. | 07-24-2014 |
20140254481 | METHOD AND APPARATUS FOR CONTROLLING CHARGING BY USING VOLUME INFORMATION OF DATA - The present disclosure relates to a method and an apparatus for controlling charging by using volume information of data, and more particularly, to a method and an apparatus for controlling charging for a UE by using volume information of data when a caching operation according to a byte caching mode or an object caching mode is performed. | 09-11-2014 |
20140366070 | METHOD AND APPARATUS FOR ASSIGNING VIDEO BITRATE IN MOBILE COMMUNICATION SYSTEM - An embodiment provides a method for supporting video transmission and reception in a bitrate selection server of a mobile communication system. The method includes receiving a metadata request of a video from a terminal. The method also includes transmitting the received metadata request to a media server based on the request; receiving a metadata response from the media server. The method also includes storing the received video metadata and transmitting the received video metadata to the terminal. The method also includes requesting subscriber information of the terminal to a Policy and Changing Rules Function (PCRF) and receiving the subscriber information. The method also includes receiving a video segment request of the video from the terminal. The method also includes determining a bitrate of the video based on at least one of the video metadata and the subscriber information. | 12-11-2014 |
20150295976 | METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING MEDIA SEGMENTS USING ADAPTIVE STREAMING - Provided are a method and apparatus for transmitting and receiving media. A method of transmitting and receiving media segments for a base station may include: receiving a segment request message from a user equipment; checking whether the segment request message contains a segment selection delegation indicator through analysis of the segment request message; obtaining, when the segment request message contains a segment selection delegation indicator, play position information from the segment request message; selecting one of two or more segments corresponding to the play position information; and receiving the selected segment from an external server and delivering the received segment to the user equipment. Embodiments of the present invention enable efficient adaptive streaming. | 10-15-2015 |
20150341467 | METHOD AND OF IMPROVING HTTP PERFORMANCE ON COMMUNICATION NETWORK AND APPARATUS ADAPTED THERETO - A method of improving Hyper Text Transfer Protocol (HTTP) performance on communication networks and an apparatus adapted to the method are provided. In a communication system including a first server, a second server and at least one connection server for connecting the first and second servers, the communication method using the first server includes: receiving a request for content from at least one client; establishing a bypass connection to directly receive data from the second server; directly receiving data about the content from the second server by using the bypass connection; and transmitting the data to the client. | 11-26-2015 |
