Abstract: User equipment includes a first communication entity that supports a transport layer protocol and a network layer protocol, and that transmits data a transmission source address of which is set to be a certain network layer address, to a network; and a second communication entity that supports the transport layer protocol and the network layer protocol, and that by commonly using the certain network layer address, is able to transmit the data the transmission source address of which is set to be the certain network layer address, to the network, wherein the second communication entity includes a storage device that stores a port number not being overlapping a port number which is used in the first communication entity, and a control device that performs determining processing which, when the received data does not include the port number, determines that the destination of the received data is the first communication entity.

Abstract: 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.

Abstract: 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.

Abstract: 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?PDU divider for dividing packet data to be transmitted to an opposite entity, into protocol data units; and a synchronous control signal generator 223 for 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.

Abstract: 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.

Abstract: A radio network controller disposed on a network, for implementing effective use of bands in use considering the characteristics of the use form of the users, not by physical expansion, the radio network controller having a user resource management section for managing information for characterizing a user connected to the radio network controller, a plurality of user signal data conversion sections for performing conversion processing of the user signal data respectively, and a resource control section for performing resource control for securing bands for the plurality of user signal data conversion sections, wherein the resource control section secures a band appropriate for the characteristics of the user by controlling the shift of calls among the plurality of user signal data conversion sections.

Abstract: A radio network controller in a mobile communication network detects characteristics of mobile devices that are wireless connected to a radio base station managed by the radio network controller. The radio network controller decides whether the mobile devices can be classified into at least one group according to the detected characteristics. When it is decided that the mobile devices can be classified into at least one group, radio base stations to which the mobile devices can be wireless connected are changed according to the classified group so that radio resources in the radio base stations can be uniformly used. By sharing the radio resources owned by a radio base station, the radio resources under the control of the radio network controller can be effectively utilized.

Abstract: The invention makes it possible to quickly confirm the safety of people in an area stricken by a disaster such as an earthquake while protecting people's privacy, even in a situation where communication calls cannot be established due to network congestion. An event reflecting an action of the user of a mobile unit in a designated area, such as a change in the location registration of the mobile unit, is detected by a user event detecting unit 18. in mobile switching equipment 12, and stored in a user event storing unit 22 in an information providing apparatus 16. In an information providing method, when there is an incoming call to a mobile unit in the designated area, for example, if the call cannot be established due to network congestion, the call is connected to an information providing unit 24 which provides user action information, by voice, to the calling party.
