Abstract:
PURPOSE: A channel allocating system and method thereof are provided to request channel allocation about a plurality of related traffic streams by using one message. CONSTITUTION: A communication unit(120) transceives messages for channel allocation and channel release with a channel response device. A correlation confirmation unit(112) checks correlation of traffic streams which receives channel allocation. The correlation confirmation unit confirms whether the traffic streams are related or not. An allocation requesting unit(114) generates a channel requesting message requesting a channel allocation about related traffic streams. The allocation requesting unit transmits the channel allocation request message to the channel responding device through the communication unit.

PURPOSE: A method and an apparatus for adjusting a signal transmission time of a terminal in a wireless network are provided to adjust a signal transmission time of plural terminals which independently operate. CONSTITUTION: A wireless communication unit(210) transmits to plural terminals a request frame including transmission time information of plural terminals. The wireless communication unit receives a response frame transferred from plural terminals from the plural terminals according to the transmission time information. A control unit(220) calculates the difference between the real arrival time and the estimated arrival time of the response frame. In addition, the control unit adjusts the transmission time information by reflecting the difference and sets up the request frame to include the adjusted transmission time information.
Abstract:
A relaying method of a repeater is provided to enable the repeater to receive/transmit traffic as maintaining the compatibility with a map. A repeater grasps one or more connection identifiers(S102), and then receives a downlink frame(S103). The repeater extracts the first map information element corresponding to the connection identifiers from the downlink frame(S104), and then extracts a data burst corresponding to the first map information element from the downlink frame(S105). The repeater extracts the second map information element corresponding to the connection identifiers from the downlink frame(S106), and then transmits the data burst through the second area corresponding to the second map information element(S107).
Abstract:
A frame transmitting/recovering method for delay-free relaying in a mobile communication system is provided to transmit the resource allocation information and the position and the modulation type of the information together. A base station or a relay station transmits a frame to another relay station in a mobile communication system. A process for assigning the area position for displaying the resource allocation information at the header of the area for transmitting data to another relay station from the base station or the relay station is performed. The frame including the information of the header and the resource allocation is transmitted. The header includes the information for assigning a modulation manner of the area for displaying resource allocation information. The header is the R-FCH(relay-frame control header). The area for displaying resource allocation information is the R-MAP(relay-maximum a posteriori). The resource allocation information is restored from the area for displaying resource allocation information.

Abstract:
PURPOSE: A signal message comparing system in a software conformance testing for a mobile terminal of an IMT-2000 asynchronous method is provided to reduce a load for message comparison and decoding by determining whether a message exchange procedure is normal by using only a signal message of a lower layer and decoding only an error-generated message. CONSTITUTION: A message receiver(50) receives a layer 3 signal message from a mobile terminal. A message manager(60) generates a comparison signal message of the same expression format as the layer 3 signal message by a user. A message judging unit(70) reads the comparison signal message and the layer 3 signal message and compares them with each other, and judges whether a message exchange procedure is in a normal/abnormal state. A message decider(80) decodes the layer 3 signal message and the comparison signal message if they are judged not to be the same. A message information factor comparator(90) compares the two messages by the unit of information factor to check whether there is an error. A screen output unit(95) outputs an information factor on a screen whenever an error occurs in the message information factor comparator(90). The message manager(60) includes a message database(65) for storing the comparison signal message generated by the user in a file format.

The built-in voice input/output unit(631) inputs a voice signal from a microphone or outputs the voice signal. The transceiving signal processor(633) transmits the voice signal of the body(620) to a wireless terminal charging device, and transmits a voice signal received from the charging device to the switching unit(632).
