摘要:
The call attempts are controlled under the traffic overload of CDMA environment provide a method in which when the message transmitted for a new call attempt is failed in the state of traffic overload, the speech quality and the number of mobile station which are on the line are maintained to the desired level by controlling the retransmitting of the message to the proper level.

A cellular capacity in a multimedia DS-CDMA system may be maximized by controlling a transmission rate of data calls. In a method for maximizing the cellular capacity, the total interference quantity is controlled by restraining the transmission rates of the respective data calls according to diminution factors of a linear, a parabola and a hyperbola; the transmission rate of the data call is increased in case a traffic load is small; and the transmission rate of the data call is decreased in case the traffic is overloaded, thereby more calls can be received and the number of subscribers having a service of voice and data calls in the CDMA circumstances may be allowed most suitably. In case a call of higher priority is newly received under a state that the data call of a high speed occupies a resource of a system for a long time, the transmission rate of the currently progressing data is controlled to receive the new call. Accordingly, the number of subscribers can be allowed at maximum by controlling the transmission rate of the data call so that more voice and data calls may be received within the CDMA system capacity.

Apparatus and system for controllably removing liquid from tofu with no or minimal cracking or deforming. An interior box contains tofu. Interior box is insertable and removable from exterior box. Interior box includes drain(s) for liquid removed from tofu, and resilient spacers on bottom to create space between bottoms of interior and exterior boxes for containing drained liquid and for cushioning tofu when pressed. A cover releasably attaches to top of nested boxes. Telescoping extender extends through cover into interior box. Extender is attached at one end to inside cover and attached at other end through a spring-loaded cap to a press plate. Extender has interior tier cylinder nested within exterior tier cylinder. Extender progressively telescopes interior cylinder out of exterior cylinder, and then telescopes exterior tier cylinder to extend press plate further into interior box to press tofu to release liquid. Spring-loaded cap on extender cushions pressure on tofu.

A method for providing uplink service from a base station to a terminal includes: transmitting information on a TCP packet and a dedicated code to a terminal; receiving a code number from the terminal using the dedicated code; searching a requesting bandwidth for the code number and allocating resources to the terminal; and receiving the ACK packet for the TCP packet through the allocated resources from the terminal.
摘要:
An apparatus for reporting location information reports location information to a base station when there is a reporting request for location information necessary for wireless location measurement from the base station and reports the location information necessary for the wireless location measurement to the base station according to a reporting period. In addition, the apparatus for reporting location information reports the location information to the base station when events are generated within the reporting period.

Disclosed are a telematics system using human body communication, a portable device having a telematics function using human body communication, and a method for providing a telematics service using human body communication. The telematics system using human body communication includes: a vehicle receiving an authentication key from at least one portable device through human body communication using a human body as a medium, and controlling the opening and closing of a door of the vehicle based on whether or not the received authentication key is valid; and a first portable device transmitting a first authentication key through a user's body in contact with the vehicle.
摘要:
A base station calculates the number of terminals which have transmitted messages at ith frame, and calculates the number of messages to be transmitted at (i+1)th frame by using the number of terminals which have transmitted the messages in the ith frame. The base station calculates a transmission probability by using the number of messages to be transmitted in the (i+1)th frame and the number of random access slots, and transmits the number of messages to be transmitted in the (i+1)th frame and the transmission probability to the plurality of terminals. The base station receives a message transmitted by a pertinent terminal, whose number of messages to be transmitted in the (i+1)th frame is greater than the number of random access slots, among the plurality of terminals, according to the result obtained by comparing the transmission probability and a random number.
