The user of a mobile station which is prepared to receive information providing services from unspecified IP (Information Providers) accesses a gateway server and performs a pre-registration procedure (S). When an IP server has information to provide to users, it constructs the information in the form of electronic mail, appends user attribute data, and sends this to the gateway server (S). Upon receiving electronic mail with attribute data, the gateway server stores the electronic mail in a third mailbox, makes a comparison of the user attributes, and calls the mobile stations of relevant users (S). A user who has received a call requests a download of the electronic mail from the gateway server (S). The gateway server sends electronic mail to the mobile station which made the request (S, S).

In a case where the F-RTO algorithm is simply combined with the exponential backoff algorithm which is being suppressed, there is a problem in that once a spurious timeout occurs, the spurious timeout continuously occurs since then. In order to solve the above problem, according to the present invention, in a communication device for transmitting data segments and receiving acknowledgements in response to the data segments, respectively and sequentially, suppressing an application of a backoff algorithm for increasing a retransmission timeout period at the time of retransmitting a data segment, and controlling the retransmission timeout period to retransmit the data segment, the spurious timeout is determined based upon the acknowledgement received immediately after the retransmission of the data segment. In an event of determining the occurrence of the spurious timeout, the retransmission timeout is increased.

Communication device and communication method

There is a need for reducing the scale of a circuit that determines and decodes code types for reception signals coded with different codes. A reception logic circuit determines and decodes code types for reception signals coded with different codes. The reception logic circuit determines one of code types for a demodulation signal corresponding to the reception signal based on a difference between codes detected during a modulation period or a non-modulation period occurring in the demodulation signal. The reception logic circuit decodes the code type in accordance with the determined code type based on the modulation period or the non-modulation period that alternately occurs in the demodulation signal. In this manner, the received data is reproduced. There is no need for a decoder specific to each code.

Semiconductor device and communication device

A transmitter device which performs window control in transmitting data for transmission through a communication network is caused to identify a mode of window control to be performed based on a communication condition under which the data transmission is performed, so as to transmit the data for transmission by performing the window control in the identified mode.

A common channel signaling network comprises a first and a second subnetwork each being composed of interconnected signaling nodes having a service entity. The first and second subnetworks employ different versions of protocol for message transmission. A common signaling node is provided for protocol conversion. As the common signaling node receives a message from a service entity of each subnetwork, it converts the message format to the protocol of the other subnetwork, and transmits it to a service entity of the other subnetwork.
