Abstract: A communication apparatus and method for an upper node in a communication system. The communication method includes assigning a Connection IDentifier (CID) set to a Relay Station (RS), generating a CID assignment message including information on the assigned CID set, and transmitting the CID assignment message to the RS.

Abstract: A character entry method and apparatus in a terminal in which characters are grouped into a plurality of character sets and a representative character of each of the character sets is imprinted on a respective key are provided. In the character entry method, when a key imprinted with a representative character is pressed, characters belonging to a character set represented by the representative character are displayed and any one of the displayed characters is marked with a selection indication. When a move key is pressed, the duration of the key press of the move key is measured and the selection indication is sequentially moved. When input of the move key is released, a character marked with the selection indication is entered.

Abstract: A character entry method and apparatus in a terminal in which characters are grouped into a plurality of character sets and a representative character of each of the character sets is imprinted on a respective key are provided. In the character entry method, when a key imprinted with a representative character is pressed, characters belonging to a character set represented by the representative character are displayed. When a directional key is pressed, the number or duration of key presses of the directional key is counted or measured. A character corresponding to the number or duration of key presses is selected among the displayed characters and entered.

In the character entry method, when a key imprinted with a representative character is pressed, characters belonging to a character set represented by the representative character are displayed and a character among the displayed characters is marked with a selection indication. When a move key is pressed, the selection indication is moved according to the direction of the move key. When an OK key is pressed, the character marked with the selection indication is entered.

Abstract: A character entry method and apparatus in a terminal in which characters are grouped into a plurality of character sets and a representative character of each of the character sets is imprinted on a respective key are provided. In the character entry method, when a key imprinted with a representative character is pressed, characters belonging to a character set represented by the representative character are displayed and a character among the displayed characters is marked with a selection indication. When a move key is pressed, the duration is identified and compared with a criterion time. If the selection indication is equal to or longer than the criterion time, the character marked with the selection indication is entered.

Abstract: An apparatus and method are disclosed for providing location-based advertisement information in a BWA communication system, in which a shop terminal provides advertisement information to a service provider server. The service provider server uses the advertisement information as accounting information and provides path guidance information to a user terminal. A Radio Access Station (“RAS”) broadcasts or selectively sends the advertisement information to the user terminal and sends path guidance approval information received from the user terminal to the service provider server. The user terminal receives the advertisement information from the RAS, sends the path guidance approval information according to user selection, receives the path guidance information from the service provider server, and invokes a path guidance function.

Abstract: Provided are an apparatus and method for managing connection identifiers (CIDs) in a multi-hop relay Broadband Wireless Access (BWA) system. An apparatus is provided for a Relay Station (RS) in a multi-hop relay cellular communication system. The apparatus includes a database, a controller, and a transmitter. The database is used for managing a Connection Identifier (CID) set assigned to the RS by a Base Station (BS). The controller accesses the database to assign one CID of the CID set to a Mobile Station (MS) when receiving a control message from the MS. The transmitter constructs a response message including the CID assigned to the MS and transmits the response message to the MS. The MS can be assigned a CID directly from the RS in a condition that the BS is not involved, so that the initial ranging procedure can be rapidly performed.

Abstract: An apparatus and method for providing EPG in a digital broadcasting system, in which an EPG connecting unit connects EPG servers of digital broadcasting channels, a program information generating unit generates program information according to program characteristics of the digital broadcasting channels, and an EPG server generates EPG information using the generated program information, and combines the generated EPG information with EPG information of the broadcasting channels. Accordingly, the program information of different broadcasting channels can be searched without switching channels, and quality of the EPG service can be improved. Moreover, users can be allowed to personally configure the EPG, thereby providing the EPG according to characteristics of the users.

Abstract: A sensor network communication system interworking with a BWA communication system and a communication method therefor are provided. In a method for measuring a predetermined target in the sensor network communication system interworking with the BWA communication system, a mobile station or a server sends a measurement request for the predetermined target to a local controller over the BWA communication system. The local controller sends the measurement request to a predetermined sensor and actuator over a wireless communication protocol. The sensor and actuator measures the predetermined target and sends the measurement value to the local controller. The local controller sends a measurement result message based on the measurement value to the mobile station or the server.

Abstract: An apparatus and method for providing subscriber information in a mobile communication system are provided. A database stores registered information containing subscriber information, a scope of persons to view the subscriber information, and an open level for the subscriber information. A wait time information management server stores the subscriber information in the database. Upon request for a call from a calling terminal, the wait time information management server searches for the subscriber information in the database and provides the searched subscriber information according to the open level to an MSC. The MSC sends wait time information based on the subscriber information received from the wait time information management server to the calling terminal.
