Abstract: In a MBMS system, a base station generates a data control task and a first header control task and second header control task corresponding to each terminal device for a MBMS function module. Each header control task synchronizes a compression state with an associated terminal device and transmits only header information to the terminal device, and the data control task distributes content information to the terminal device separately from header information.

Abstract: A mobile terminal device includes a first processor and a second processor. The first processor executes a first process for communication using a first wireless scheme and outputs line setting information for the communication using the first wireless scheme before performing reset process when an interrupt request that triggers the reset process occurs in the first processor during the communication using the first wireless scheme. The second processor executes a second process for communication using a second wireless scheme and outputs a connection request for the communication using the second wireless scheme when the second processor acquires the line setting information from the first processor.

Abstract: There is provided a communication device to transfer a received packet to a data terminal device, the communication device being coupled to the data terminal device in a wire or wireless system, the communication device including: a determining unit configured to determine whether or not a compression state of a compressed header added to the packet is a predetermined compression state; and a transfer unit configured to transfer the compressed header to the data terminal device and to transmit an activation request signal used on case of activating a routing module using an RoHC algorithm to the data terminal device including the routing module, when the compression state of the compressed header is the predetermined compression state, or to decompress the compressed header and to transmit the decompressed header to the data terminal device, when the compression state of the compressed header is not the predetermined compression state.

Abstract: A communication device is provided, with which packet synchronization is achieved based on input data transmitted by an external device, without using a special protocol between the communication device and the external device. An external TE attaches a CRC code to each packet before transferring data to a mobile terminal (UE). Data is bulk transferred from the external TE to the UE according to a USB protocol. At the UE, the CRC code of the input data is detected at a CRC processing unit 19. When the CRC code is detected, a first packet detecting unit 14 detects the first packet by reading a packet length. Once the first packet is detected, a second packet detection unit 15a detects succeeding packets by sequentially reading packet lengths.

Abstract: The wireless base station sends control data relating to the processing, belonging to the upper layer (the second layer) of the first layer, to the wireless terminal through the downlink channel. Upon reception of the control data through the downlink data channel, the wireless terminal sends the response data, as a response to the control data, to the wireless base station through the control channel. The wireless base station detects the response data from the received data through the control channel, and then controls the processing belonging to the upper layer based on the response data. The above processing eliminates establishing a data channel to the wireless base station only for the response data as a response to the processing belonging to the upper layer.

Abstract: An error-information compressing apparatus acquires a hardware error from a hardware, stores reference data in a storing unit, compresses the hardware error by using the reference data into compressed hardware error, and writes the compressed hardware error in a storage device. The hardware error is compressed by calculating a difference between the hardware error acquired and the reference data. If the volume of the compressed hardware error is larger than the original hardware error, the reference data is updated with the compressed hardware error.
