A method and apparatus for packet aggregation in a power line communication network (PLC) are provided. The method of aggregating packets includes: by performing a PLC channel estimation, determining whether or not a channel condition is good; if the channel condition is good, determining whether or not the data desired to be transmitted is suitable for packet aggregation according to the type of data; and if the channel condition is good and the data desired to be transmitted is suitable for the packet aggregation, aggregating packets of the data desired to be transmitted. Since a decision on whether or not to aggregate packets is determined according to a channel condition at a physical level and the type of data at an application level, packet aggregation can be performed in appropriate response to the frequently changing condition of a channel and the characteristic of the data desired to be transmitted.

The present invention is a method and system, with the system comprising an CPNS server and an end-point terminal for connecting the end-point terminal to a plurality of mobile communication terminals for providing the end-point terminal with a variety of services in a CPNS environment. The CPNS server makes a request for a CPNS service via a second mobile communication terminal, analyzes the request as transmitted to provide the end terminal with the service. The end-point terminal is connected to the first mobile communication terminal through a short-range wireless communication network for performing the CPNS service and is connected to a second mobile communication terminal through short-range wireless communication during the performance of the CPNS server to request and receive specific CPNS service from the CPNS server. Since the end-point terminal is connected to a plurality of mobile communication terminals and provided with CPNS services, the end-point terminal can simultaneously provide a variety of services.

The present invention relates to a system and method for providing relevant sound content from an end-point terminal. The invention enables music files in the end-point terminal to be utilized in various kinds of sounds used while using a mobile communication terminal with the system including the end point terminal, the mobile communication terminal, and a service server. The mobile communication terminal is connected to the end-point terminal through a local area network and to the service server through a mobile communication network and is in charge of data transmission between the end-point terminal and the service server for downloading the relevant sound content from the service server which transmits the relevant sound content corresponding to the music file to the mobile communication terminal.
摘要:
Disclosed herein are a system and method for transmitting content, a service server, a mobile communication terminal and a storage medium. The system includes an end device connected to a first mobile communication terminal via a local area communication network, and configured to transmit content to be transmitted to a second mobile communication terminal, together with a message transmission request, to the first mobile communication terminal; and the first mobile communication terminal connected to the end device via the local area communication network, connected to a service server via a mobile communication network, and configured to display a message transmission window for inputting a message and a recipient's number on a screen when the message transmission request is received from the end device, and to transmit a Multimedia Message Service message (MMS), to which the content received from the end device is attached, to the second mobile communication terminal.

A wireless communication terminal is provided for use in interactive communication with a base station (BS) to allow exchange of displayed image related information. A display is configured to display a broadcast image from the BS. The broadcast image is associated with a time stamp recognized by the BS. The broadcast image includes an object displayed on the display. An input module is configured to recognize a selected position on the display associated with the object. A controller is in communication with the display and the input module. The controller is configured to associate the selected position with the object, to provide coordinate data corresponding to the selected position, to provide to the BS a time reference in relation to the time stamp when the selected position is recognized, to receive from the BS object information related to the object, and to display the object information received from the BS.

Provided are a channel time allocation method and apparatus adopting the same. The channel time allocation method includes: (a) receiving a request of registering in a network from a device; (b) determining whether the network supplying a service required by the device exists; and (c) if the network supplying the requested service exists, performing a procedure of registering in the network, and if the network supplying the requested service does not exist, generating a new network. Since existing MAC protocols can be used in the channel time allocation method, an optimum service is provided in a network environment in which different kinds of services coexist.
摘要:
A method of negotiating channel sharing between adjacent cells when there are a plurality of cells in a power line communication (PLC) network. The method includes attempting to negotiate the channel sharing during a minimum contention access period (CAP) which starts after a maximum beacon period ends and ends before a CAP of each PLC cell ends, wherein the maximum beacon period indicates a maximum size that a beacon frame in a super-frame transmitted from a coordinator of each PLC cell can have. When an attempt to negotiate the channel sharing is made using this method, interference does not occur during channel sharing negotiation, and effective channel sharing can be achieved, thereby eliminating interference between adjacent cells.
