Abstract
A femtocell gateway apparatus arranged on a mobile IMS network comprises a conversion unit that when receiving a request from a terminal via a mobile network, transfers the request to a femtocell access point located in a home, reads a stream or file including at least one of video and audio, from at least one of devices connected to the femtocell access point and devices connected thereto via a home network, subjects the read stream or file to a conversion suitable for at least one of the capability of the terminal and the characteristics of the network, and outputs the stream or file converted. The output packet is then sent through a packet forwarding apparatus on the mobile network to the terminal.
Claims20
A gateway apparatus comprising:
- a control signal conversion unit that receives a selection result of a content from a server, said server being accessed by a terminal via a network for authentication to select the content, said control signal conversion unit, on reception of a request from a terminal via a mobile network, identifying a type of said terminal to transmit a request including information on said content selected to a network element installed in a home;
- a reception unit that receives a stream or file including a video and/or audio which is said content selected by said terminal and read out via said network element to extract content information;
- a conversion instruction unit that receives said terminal type information to obtain capability information corresponding to said type of said terminal, said conversion instruction unit creating conversion information for performing conversion of said stream or file based on said content information and said capability information corresponding to said type of said terminal;
- a conversion unit that transcodes said stream or performs file format conversion on said stream or said file received by said reception unit in accordance with said conversion information;
- a protocol conversion unit that converts a protocol of said stream or said file converted by said conversion unit into a protocol corresponding to a node apparatus arranged on said mobile network, said node apparatus including a packet forwarding apparatus connected to a radio network control apparatus provided on said mobile network, or a radio network control apparatus connected to a switching equipment provided on said mobile network;
- and
- a transmission unit that sends said stream or said file subjected to said conversion to said terminal via connection to said packet forwarding apparatus or to said switching equipment, using said converted protocol, and via said radio network control apparatus.

A gateway method by a gateway apparatus, said method comprising:
- receiving a selection result of a content from a server, said server being accessed by a terminal via a network for authentication to select the content,
- on reception of a request from a terminal via a mobile network, identifying a type of said terminal to transmit a request including information on said content selected to a network element installed in a home;
- receiving a stream or file that is said content selected by said terminal and includes a video and/or audio read via said network element to extract content information;
- obtain capability information corresponding to said type of said terminal and creating conversion information for performing conversion of said stream or file based on said content information and said capability information corresponding to said type of said terminal;
- transcoding said stream or performing file format conversion on said stream or said file received in accordance with said conversion information;
- converting a protocol of said stream or said file converted in accordance with said conversion information into a protocol corresponding to a node apparatus arranged on said mobile network, said node apparatus including a packet forwarding apparatus connected to a radio network control apparatus provided on said mobile network, or a radio network control apparatus connected to a switching equipment provided on said mobile network;
- and
- sending said stream or said file subjected to said conversion to said terminal via connection to said packet forwarding apparatus or to said switching equipment, using said converted protocol, and via said radio network control apparatus.
5 more elements
A communication system comprising:
- a mobile network;
- a network element installed in a home;
- and
- a gateway apparatus connected to said mobile network and network element,
- said mobile network comprising a node apparatus, wherein
- said gateway apparatus receives a selection result of a content from a server, said server being accessed by a terminal via a network for authentication to select the content,
- said gateway apparatus, on reception of a request from a terminal via said mobile network, identifying a type of said terminal to transmit a request including information on said content selected to said network element,
- said network element reads a stream or file that is said content selected by said terminal and includes a video and/or audio from a device installed in said home and connected to said network element and sends said stream or said file read to said gateway apparatus,
- said gateway apparatus receives a stream or file including a video and/or audio which is said content selected by said terminal and read out via said network element to extract content information,
- said gateway apparatus obtains capability information corresponding to said type of said terminal and creates conversion information for performing conversion of said stream or file based on said content information and said capability information corresponding to said type of said terminal;
- said gateway apparatus transcodes said stream or performs file format conversion on said stream or said file in accordance with said conversion information, converts a protocol of said stream or said file converted in accordance with conversion information into a protocol corresponding to a node apparatus arranged on said mobile network, said node apparatus including a packet forwarding apparatus connected to a radio network control apparatus provided on said mobile network, or a radio network control apparatus connected to a switching equipment provided on said mobile network, and
- said gateway apparatus sends said stream or said file subjected to said conversion to said terminal via connection to said packet forwarding apparatus or to said switching equipment, using said converted protocol, and via said radio network control apparatus.
