Mobile equipment includes a second control unit connected to a plurality of first control units performing control of an application function. The second control unit includes a storage unit, a setting unit, a transmitting unit, and a selecting unit. The storage unit stores selection information and connecting-destination specifying information associating each other. The setting unit sets the connecting-destination specifying information for a connecting-destination connected with the mobile equipment via a connection between the mobile equipment and a communication network. The transmitting unit transmits the connecting-destination specifying information set by the setting unit to the first control unit having the application being an establishment requestor of the connection. The selecting unit selects the connection for transferring user data based on the connecting-destination specifying information of the user data when the user data is received from the first control unit having the application being the establishment requestor of the connection.

Mobile equipment and packet filtering method

In a packet transmission device and control method thereof which can improve the transmission rate of a packet without adding a high speed user data-conversion card, when packet data is inputted through a single arbitrary channel among a plurality of channels, from among a predetermined number of low speed user data-conversion cards provided common to the plurality of channels, the low speed user data-conversion cards by a number corresponding to a ratio between an output transmission rate of the low speed user data-conversion card and an input transmission rate of the packet data are extracted. The packet data is sequentially and cyclically distributed to the low speed user data-conversion cards extracted. Predetermined length user data outputted from the low speed user data-conversion cards are converted into a frame of HSDPA (High Speed Downlink Packet Access) system and multiplexed into a single channel HS-DSCH (High Speed Downlink Shared Channel) to be outputted.

Packet transmission device and control method thereof

To provide a packet communicating apparatus that can reduce a padding area. A packet communicating apparatus used in a high speed packet communication in a radio mobile communication network includes: an SDU&#x2192;PDU divider for dividing packet data to be transmitted to an opposite entity, into protocol data units; and a synchronous control signal generatorfor jointly putting a control signal to change a protocol data unit length, on a padding area of a protocol data unit occurring at a time of the division.

Packet communicating apparatus

In a retransmission control method and device which can suppress or expedite a retransmission of user data depending on a processing congestion status or the like on a receiving side, a user equipment on a data receiving side transmits to a radio network control device on a data transmitting side, when redundantly receiving an ACK request included in same user data, control data for extending a timeout period of a polling timer which is a retransmission time interval of user data for a subsequent ACK request by e.g. 10 ms. The radio network control device having received the control data extends the timeout period based on the control data. Alternatively, the radio network control device reduces, when receiving an ACK response from the user equipment within the timeout period, a timeout period of user data for a subsequent ACK request to less than the timeout period presently set.
