Abstract: A delivery node alternately connects to a first wireless terminal and a second wireless terminal. When a first packet with a virtual IP address of the second wireless terminal as a destination IP address is output from a first application to a virtual network interface, the first wireless terminal encapsulates the first packet with the use of an encapsulation header and transmits to the delivery node. The delivery node encapsulates the first packet obtained by decapsulating the received encapsulation packet again, and transmits to the second wireless terminal. The second wireless terminal transmits the first packet obtained by decapsulating the received encapsulation packet to a second application through a virtual network interface.

Abstract: Problems with communication interface selection control using a fluctuation control equation are that it is difficult for the control to address large environmental variations and that the control requires parameter adjustments according to environments, which incurs operating cost. A communication method according to the present invention includes the step of observing communication environment conditions to generate communication environment data, generating fluctuation information by using the communication environment data as the data occurs, and allocating communication resources by performing attractor selection control on the basis of the fluctuation information. The step of generating fluctuation information comprises the step of using a fluctuation equation to perform fluctuation equation control utilizing the fluctuation information as the fluctuation information occurs.

Abstract: Before a mobile station is in dormancy, power control channels of forward and reverse links are established between the mobile station and a base station independently of traffic channels of forward and reverse links. When the mobile station is in dormancy, a dormant power control signal is transmitted from the base station to the mobile station through the power control channel of the forward link. Then a dormant power control process is carried out at the mobile station, in accordance with the dormant power control signal transmitted from the base station, to produce a reference data signal subject to the dormant power control process, In response to the power-controlled data signal, the base station produces the dormant power control signal in accordance with a reception level of the reference data signal. Thus, closed loop power control for dormant mobile station is achieved.

Abstract: A mobile communication device has a delay locked loop circuit for carrying out a tracking synchronization of a reception signal. The reception signal may be a spread spectrum signal. The delay locked loop circuit comprises a generating section for generating an early signal and first and second late signals which are different in phase from one another. A multiplying section is for multiplying the reception signal by each of the early signal and the first and the second late signals to produce first through third multiplied signals. A producing section produces an tracking error signal in accordance with the first through the third multiplied signals. A supplying section supplies a clock signal to the generating section on the basis of the tracking error signal to make the generating section generate the early signal and the first and the second late signals.

Abstract: In a code division multiple access mobile communication system, a communication signal is modulated and multiplexed with different diffusion codes and is used in data communication between a base station (30) and each of mobile units (40, 41, 42). The communication signal is a time division multiplex signal with a repeated frame having a plurality of time slots (TS0, TS1, TS2) assigned to different radio channels, respectively. A slot synchronous signal is produced in accordance with a reference clock signal of a global positioning system. The time slots are synchronized between the base station and each of the mobile units in accordance with the slot synchronous signal.

Abstract: In a CDMA communication system using a common frequency band at a forward channel and a reverse channel, a first detection section detects traffic in the reverse channel to produce a first detected signal indicative of the traffic in the reverse channel. A first assigning section (131) assigns reverse spreading codes to the reverse channel. The first assigning section (132) makes, in response to the first detected signal, number of the reverse spreading codes change. A second detection section (231) detects traffic in the forward channel to produce a second detected signal indicative of the traffic in the forward channel. A second assigning section (232) assigns forward spreading codes to the forward channel. The second assigning section makes, in response to the second detected signal, number of the forward spreading code change.
