Description

Data transmission control device and method of mobile communication system

The present invention relates to a data transmission apparatus and method of a mobile communication system, and more particularly, to an apparatus and method capable of controlling the communication of data in accordance with the amount of data transmission.

In general, the mobile communication system of the Code Division Multiple Access (CDMA) method has been developed from the IS-95 standard, which focuses on voice, to the cdma2000 standard, which is capable of transmitting high-speed data as well as voice. Reached. According to the cdma2000 standard, services such as high quality voice, moving picture, and internet search are possible.

The cdma2000 standard has a dedicated control channel unlike the CDMA mobile communication system. The dedicated control channel has a low frame transmission error rate and basically supports a data rate of 9.6 kbps or 14.4 kbps. The dedicated control channel also supports a discontinuous transmission mode. The discontinuous transmission mode means that it is not necessary to transmit frame data on a physical channel if necessary. That is, in the discontinuous mode, when there is data to be transmitted, data is transmitted through the corresponding channel, and when there is no data to be transmitted, it is a mode of stopping data transmission. Since the dedicated control channel supports a discontinuous transmission mode and only supports transmission of 9.6 kbps or 14.4 kbps, one frame data of 9.6 kbps or 14.4 kbps may be transmitted or frame data may not be transmitted in a frame period of 20 ms.

In the following description, a frame transmitted in a transmission allowed by a dedicated control channel, such as the transmission of 9.6 kbps or 14.4 kbps, will be referred to as a full rate frame.

As described above, since the dedicated control channel may or may not transmit frame data, it is difficult for the base station to predict the size of the physical resource to be occupied by the terminal. That is, in the worst case, since the terminal can continue to send a full rate frame, the base station should think that the terminal will continue to use 9.6 kbps or 14.4 kbps physical resources in preparation for the worst case.

However, if the base station gives the terminal a condition to generate a full rate frame and the terminal can transmit the frame only when the condition is satisfied, the base station can lower the average estimated physical resources to be used by the terminal. Will be. For example, if the base station instructs the terminal to send a full rate frame once and then nothing at all, then the base station can predict the physical resource usage of the terminal in half. Therefore, if a transmission control method for the dedicated control channel is used, the base station can lower the average physical resource usage of the terminal as much as desired.

Accordingly, an object of the present invention is to provide an apparatus and method for controlling the number of transmissions according to the amount of data when a base station and a terminal transmit packet data through a dedicated control channel and a basic channel in a mobile communication system. In providing.

Another object of the present invention is to provide an apparatus and method for transmitting information for coordinating data transmission of a terminal by a base station in a mobile communication system, and controlling data transmission of a corresponding channel according to the information to communicate with the terminal. have.

Another object of the present invention is to provide an apparatus and method for communicating with a base station by controlling a data transmission of a channel according to the control information after the terminal receives the transmission control information of the data transmitted from the base station in a mobile communication system. In providing.

DETAILED DESCRIPTION A detailed description of preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be noted that the same components in the drawings represent the same numerals wherever possible.

In the following description specific details such as the values of the variables controlling the data transfer and the channel used for the data transfer are presented to provide a more general understanding of the invention. It will be apparent to one of ordinary skill in the art that the present invention may be readily practiced without these specific details and also by their modifications.

The data transmission control method of a mobile communication system according to an embodiment of the present invention gives a base station a condition for generating a full rate frame to the terminal, and allows the terminal to transmit the frame only when the condition is satisfied. Accordingly, data transmission can be coordinated between the base station and the terminal, thereby lowering an average of physical resources. For example, if the base station sends a full rate frame to the terminal once and then stops transmitting the frame data, the base station can predict the average physical resource usage of the terminal in half. Therefore, when the packet data is transmitted between the base station and the terminal through the dedicated control channel or the basic channel in the mobile communication system, the base station controls the transmission by estimating the amount of data communicated through the dedicated control channel. Physical resource usage can be reduced on average.

1A is a diagram illustrating a configuration of an apparatus for transmitting RLP data according to an embodiment of the present invention. In this case, the physical channel apparatus for transmitting the RLP data is assumed to be a dedicated control channel apparatus.

Referring to FIG. 1A, a dedicated control channel modulator 11 for transmitting a frame for a dedicated control channel, a multiplexer 13 for generating information bits of a frame to be transmitted, and a radio link protocol ( It consists of a processor 15 that performs Radio Link Protocol (RLP). The RLP frame transmission apparatus having the configuration as shown in FIG. 1A has the same configuration in both the terminal and the base station.

FIG. 1B is a diagram showing the detailed configuration of the radio link protocol processor 11 of FIG. 1A.

Referring to FIG. 1B, a processor that performs the radio link protocol includes a radio link protocol controller 21 for managing an operation of a radio link protocol, and a radio link protocol frame generator for generating the radio link protocol frame. frame generator 25 and a memory 23 for storing data to be transmitted or data already transmitted. In FIG. 1B, the first counter NC 31 is a counter for storing the number of frame generations, the second counter LC 33 is a counter for storing the number of generated full rate new data frames, and the register N 27 is a counter for storing the number of frame generations. L register 29 is a register that stores the maximum number of full-rate new data frames that can be created.

Therefore, the values stored in the "N" and "L" registers are reference values initially transmitted from the base station controller to the radio link protocol processor of the base station and the radio link protocol processor of the terminal, and the "N" value sets the number of frame transmissions. The first reference value is a reference value, and the "L" value is a second reference value representing the number of times of new frame data actually transmitted within the first reference value N times. For example, assuming that N = 5 and L = 3, the number of actual frames is transmitted three times in five frame data transmission intervals.

In an embodiment of the present invention, a channel for transmitting and stopping frame data according to the amount of data may be a dedicated control channel, a basic channel, and / or an additional channel. In the following description, it is assumed that the channel is a dedicated control channel.

In the mobile communication system according to an embodiment of the present invention, a base station and a terminal control a transmission of RLP frame data as follows. First, it is assumed that a dedicated control channel is already connected between the base station and the terminal.

The base station controller informs the radio link protocol controller 21 of the terminal and the base station of the number of frame generations and the maximum number of new data frames at a full rate among the number of generated frames. Here, the number of frames generated and the maximum number of frames that can be generated are used as the same meaning as the number of frames generated and the maximum number of frames that can be generated.

An embodiment of the above process is as follows. The base station controller transmits one byte of control information through a signaling message to the radio link protocol controller 11 existing in the terminal. The base station controller also conveys one byte of control information to the radio link protocol controller 11 present in the base station. Control information transmitted to the radio link protocol controller 11 is configured as shown in Table 1 below.

field Length in bits Control value index 3 bit reservation 2 bit Information type 3 bit

When the value written in the information type in the <Table 1> is '101', it means that the control information for the transmission control proposed in the embodiment of the present invention is included. At this time, the radio link protocol controller 21 uses the table shown in Table 2 below to find the maximum number of frame generation and the maximum number of full rate new data frames that can be generated.

Control value index Frame generation count Max count '000''001''010''011' 1424 1311

The radio link protocol controller 21 having the control information received from the base station controller stores the frame generation number in N, and stores the maximum number in which the full rate new data frame can be generated in L. At this time, if the base station controller does not inform the frame generation number control information, the radio link protocol designates an N value of 1. Further, if the base station controller does not inform the maximum number of the full rate new data frames that can be generated, the radio protocol designates the L value to an infinitely large value.

The radio link protocol controller 21 may be a radio link protocol controller of a base station or a radio link protocol controller of a terminal. That is, the variable values output from the base station controller are transmitted to the radio link protocol controller of the base station and also to the radio link protocol controller of the terminal. As described above, the base station controller is transmitted to the base station radio link protocol and the radio link protocol of the terminal during channel set-up or communication, and each radio link protocol controls data transmission of the corresponding channel according to the set value. In this case, it is assumed that a channel controlling the data transmission is a dedicated control channel or a basic channel. In this case, it is assumed that data transmitted on the channels is packet data.

The radio link protocol controller 21 sets the first counter NC, which stores the number of frame generation, to 0, every time the N and L values are newly set, and sets a second counter LC to store the number of generated full rate new data frames. Set to zero.

When it is time to transmit a frame on the dedicated control channel, the devices operate as follows. Every 20 ms, the multiplexer 13 determines whether it can transmit a radio link protocol frame. If so, determine the size of the radio link protocol frame to be transmitted this time. The multiplexer 13 requests the frame generation while notifying the radio link protocol processor 11 of the determined size.

The frame generation request sent from the multiplexer 13 is transmitted to the radio link protocol controller 21 inside the radio link protocol processor 11. The radio link protocol controller 21 checks whether a new data frame can be generated at present. Since the radio link protocol specifies that data frames to be retransmitted or transmitted request control frames are transmitted first, these frames must not be waiting for transmission before new data frames can be transmitted. In addition, data to be transmitted must exist in the memory 23 before a new data frame can be transmitted. Thus, if these conditions are not satisfied, the radio link protocol controller 21 instructs the radio link protocol frame generator 25 to generate an appropriate frame according to the radio link protocol specification.

If a new data frame can be generated, the radio link protocol controller 21 checks whether the size allowed by the multiplexer 13 is equal to the full rate frame size. If not, the radio link protocol controller 21 instructs the radio link protocol frame generator 25 to generate a new data frame of the specified size. The radio link protocol frame generator 25 generates a frame having a size allowed by the frame generation control signal of the radio link protocol frame controller 21 and transfers the generated frame to the multiplexer 13.

If a new data frame can be generated and the size allowed by the multiplexer 13 is a size capable of generating a full rate frame, the radio link protocol controller 21 performs the flowchart of FIG.

Referring to FIG. 2, in step 211, the radio link protocol sets the value of the counter LC that stores the number of full-rate new data frames and the value of the register L that stores the maximum number of full-rate new frames. Compare If the L value is smaller than the LC value, the flow proceeds to step 215 where no RLP frame data is transmitted. Instructs the radio link protocol frame generator 25 to generate an idle frame. The radio link protocol frame generator 25 generates and transmits an idle frame to the multiplexer 13. The multiplexer 13 discards the generated idle frame when the idle frame is generated, and transmits a transmission gain of 0 to the dedicated control channel modulator 15. Command to do The dedicated control channel modulator 15 sets the transmission gain to 0 according to the command of the multiplexer 13, resulting in substantially no data frames being transmitted on the dedicated control channel.

However, if the LC value is greater than or equal to the L value in step 211, in step 213, the radio link protocol controller instructs the radio link protocol frame generator to generate a full rate new data frame, and then Increase the value by one. After transmission on the dedicated control channel, the value of the counter LC is increased by one.

After performing step 213 or step 215, the radio link protocol controller 21 increases the value of the first counter NC, which stores the number of frame generation, in step 217, and the value of the counter counter NC is N in step 219. Is greater than or equal to At this time, if the value of the first counter NC is greater than or equal to the N value, the counter NC and LC values are initialized to zero and terminated in step 221. If the NC value is greater than the N value, the counter ends.

When the radio link protocol frame generator 25 receives a command to generate a full rate new data frame from the radio link protocol controller 21, the radio link protocol frame generator 25 receives new data to be transmitted from the memory 23, generates a full rate new data frame, and delivers the new data frame to the multiplexer 13. The multiplexer 13 makes this into the information bits of the dedicated control channel frame and passes it to the dedicated control channel modulator 15. The dedicated control channel modulator 15 configures the received information bits into a dedicated control channel frame and then transmits the frame through the dedicated control channel.

3 is a diagram illustrating a data transmission control process of a mobile communication system according to another embodiment of the present invention.

Referring to FIG. 3, the radio link protocol controller 21 stores the value of the counter LC that stores the number of full-rate new data frames and the maximum number that can generate the full-rate new frame in step 311. Compare the values of. At this time, if the L value is smaller than the LC value, it is detected in step 311 and proceeds to step 319 does not transmit the RLP frame data.

However, if the LC value is smaller than the L value in step 311, the N has a finite value in step 313, and it is checked whether N-L ≦ NC-LC. Herein, the case where N has an infinite value is a case where the base station controller does not know the number of frame generation as described above. When the number of frame generation is normally applied to the radio link protocol controller 21, the N value has a finite value. In addition, the value obtained by subtracting the maximum number of full-rate new data frames generated from the number of frame generations (that is, the difference between NLs) indicates the number of times that the radio link protocol stops transmitting and stores the number of frame generations. The subtracted value (difference of NC-LC) of the value of the counter LC, which stores the number of full-rate data frames, denotes the number of times that the radio link protocol has already stopped transmitting the frame (ie, the number of times of break). Therefore, when N has a finite value in step 313 and the NL value is smaller than the NC-LC value, that is, when the radio link protocol controller 21 transmits data, the radio link protocol controller 21 in step 321 is performed. After generating a full-rate new data frame and transmitting it on the dedicated control channel, the value of the counter LC is increased by one.

However, if the N has an infinite value or the NL value is greater than or equal to the NC-LC value in step 313, the radio link protocol controller 21 generates a random number greater than 0 and less than 1 in step 315. Store the generated value in register P. In operation 317, the random number value stored in the register P is compared with the specified random number Pr. If the random number value obtained in step 315 is greater than or equal to the specified random number value Pr, proceed to step 321 to generate and transmit a full rate new data frame, and if small, go to step 319 to generate an RLP frame. Do not.

After performing step 321 or step 319, the radio link protocol controller 21 increases the value of the counter NC that stores the number of frame generation in step 323, and in step 325 the value of the counter NC is greater than the N value. Check for equality. In this case, if the NC value is greater than or equal to the N value, the NC and LC values are initialized to zero and terminated in step 327.

As shown in FIG. 2, the radio link protocol controller 21 first checks whether the base station controller generates the number of full-rate new data frames. At this time, if the LC value is smaller than the L value, a full rate new data frame may be further generated. If the LC value is smaller than the L value, the radio link protocol controller 21 checks whether the base station controller rests without sending a full rate new data frame. At this time, if the frame generation number N specified by the base station controller is infinitely large, the number of times of rest is equally infinitely large, so the radio link protocol controller 21 checks whether a full-rate new data frame can be generated at this time. If the frame generation number N is not infinitely large, the value designated by the base station controller (that is, the difference between the N value and the L value designated by the base station controller) is a number of times of rest. See if it is less than or equal to the number of times (ie the difference between NC and LC). If the difference between N and L is less than or equal to the difference between NC and LC, the radio link protocol controller 21 generates a full-rate new data frame and transmits it since it is sufficiently rested.

However, if the difference between N and L is greater than the difference between NC and LC, the radio link protocol controller 21 checks whether a new full data frame can be generated at this time. To this end, the radio link protocol controller 21 generates one random number larger than zero and smaller than one. If the generated random number is smaller than the number Pr designated by the system, the radio link protocol controller 21 does not generate a frame. Therefore, no radio link protocol frames are sent to the dedicated control channel or base channel. However, if the generated random number is greater than or equal to the random number Pr designated by the base station controller, the radio link protocol controller 21 generates a full rate new data frame and transmits the generated data frame. Therefore, the data frame is transmitted to the dedicated control channel.

In the process, if the base station controller designates 0 as Pr, the radio link protocol controller 21 generates a full rate new data frame and transmits the generated data frame. If the base station controller designates 1 as Pr, the radio is The link protocol controller 21 ensures that no full rate new data RLP frame is transmitted on the dedicated control channel or the base channel. In order to prevent the full rate new data RLP frame from being transmitted as described above, the radio link protocol controller 21 transmits an idle RLP frame to the multiplexing device once, and the idler is in the case of the dedicated control channel. In this case, the basic channel is transmitted as it is without transmitting the RLP frame.

When the LC value is greater than or equal to the L value in the comparison of the LC value and the L value, the radio link protocol controller 21 ensures that no full-rate new data RLP frame is transmitted on the dedicated control channel or the base channel.

After the procedure, the radio link protocol controller 21 increments the NC by one. And if the increased NC value is greater than or equal to the N value, the radio link protocol controller 21 sets both the NC value and the LC value to zero. When all of these processes are completed, the radio link protocol controller 21 ends the operation.

4 is a diagram illustrating a data transmission control method of a mobile communication system according to another embodiment of the present invention.

Referring to FIG. 4, the radio link protocol controller 21 generates a random number greater than 0 and less than 1 in step 411, and stores the generated value in the register P. In operation 413, the random number value stored in the register P is compared with the specified random number Pr. In this case, when the random number value obtained in step 411 is greater than or equal to the specified random number value Pr, the process proceeds to step 415 to generate and transmit a full rate new data frame. In the case where the random number value is small, it proceeds to step 417 and does not generate an RLP frame.

After performing step 415 or step 417, the radio link protocol controller 21 increases the value of the counter NC that stores the number of frame generation in step 419, and in step 421, the value of the counter NC is greater than N. Check for equality. In this case, if the NC value is greater than or equal to the N value, the NC and LC values are initialized to zero and terminated in step 423. If the NC value is greater than the N value, the NC value is terminated.

FIG. 4 illustrates another method of simply controlling transmission by modifying the transmission control method shown in FIG. In FIG. 4, unlike the process of FIG. 2, a randomized data P is generated immediately to generate a full-rate new data frame by comparing the generated random number P to a value greater than the specified value Pr. Decide what to send.

The radio link protocol controller 21 may transmit a new data frame in a full-rate RLP frame, and when there is new RLP frame data to be transmitted, a process designated among the processes of FIG. 2, FIG. 3, or FIG. Do this.

The radio link protocol controller 21 increases the LC value and the NC value by one if the system satisfies the condition, even if the system fails to send a full rate new data frame. At this time, if the increased NC value is greater than or equal to the N value, the radio link protocol controller 21 sets both the NC and LC values to zero.

Referring to FIG. 5, the operation of increasing the LC value and the NC value is performed. If a condition is required to transmit a full-rate new data frame or increase the NC value and the LC value simultaneously, steps 511 and 513 are continuously performed. While increasing the LC and NC values one by one. In step 515, it is checked whether the value of the counter NC is greater than or equal to an N value. At this time, if the value of the NC is greater than or equal to the N value, the NC and LC values are initialized to zero and terminated in step 517. If the NC value is greater than the N value, the process ends.

At this time, the embodiment of the present invention proposes the following conditions as conditions that can simultaneously increase the LC value and the NC value as described in FIG.

1. When retransmission frames are sent in full-rate RLP frames.

2. Create new data or retransmission frames that are smaller than full-rate RLP frames.

3. Create a control RLP frame.

4. When a blank RLP frame is generated by the command of the multiplexing device.

Of these four conditions, the base station controller designates no conditions or designates various conditions so that the radio link protocol controller 21 can increase the LC value and the NC value. If the full rate new data frame cannot be sent, the NC value is increased by one if the condition specified by the base station controller is satisfied. At this time, if the increased NC value is greater than or equal to N, the radio link protocol controller 21 sets both the NC and LC values to zero.

The operation of increasing the NC value will be described with reference to FIG. 6. If a condition to increase the NC value occurs, the NC value is increased by one after step 611, and the value of the counter NC is greater than the N value in step 613. To see if it is equal to In this case, if the NC value is greater than or equal to the N value, the NC and LC values are initialized to zero and terminated in step 615. If the NC value is larger than the N value, the NC value is terminated.

In the conditions in which only the NC value as shown in FIG. 6 can be increased, an embodiment of the present invention proposes the following conditions.

1. When retransmission frames are sent in full-rate RLP frames.

2. Create new data or retransmission frames that are smaller than full-rate RLP frames.

3. Create a control RLP frame.

4. When a blank RLP frame is generated by the command of the multiplexing device.

5. No RLP frames are sent on the dedicated control channel.

However, if any of the above five conditions is already designated as a condition that can simultaneously increase the LC value and the NC value, it should not be used as a condition that can only increase the NC value as described above. Accordingly, among the four conditions, the base station controller does not designate any condition or designates various conditions among the conditions that are not designated as the conditions for increasing the LC value and the NC value at the same time. Allow to increase the value.

The radio link protocol controller 21 may reset the transmission control method generated at a predetermined interval by setting the NC and LC values to 0 when the condition is satisfied at any time. As the conditions for resetting the present invention, the following conditions are proposed.

1. New data to send after the radio link protocol generates a new full-rate data frame.

If no site remains.

2. The radio link protocol generates the idle frame itself.

By resetting the method of generating at regular intervals according to the condition, the radio link protocol can immediately send a full rate new data frame when the next data to be sent occurs. The resetting process operates as follows.

When the radio link protocol controller 21 receives a frame generation request from the multiplexer 13, the radio link protocol controller 21 performs the transmission control process when it is possible to generate the new data frame, otherwise the frame is appropriate to the radio link protocol generator 25 according to the radio link protocol standard. Command to create

However, if there is no data to be sent to the memory, the radio link protocol controller 21 instructs the radio link protocol generator 25 to generate an idle frame and sets both the NC and LC values to 0 to reset the transmission control method. This resetting process allows new data frames to be immediately transferred when new data to be sent on the memory 23 is generated.

As described above, the mobile communication system according to the embodiment of the present invention predicts the amount of data communicated between the base station and the terminal to set the maximum number of new frame data that can be transmitted with respect to the number of frame generation, and according to the setting values Run and stop the transmission of the. Accordingly, there is an advantage in that the physical channel resources of the terminal can be efficiently used in the mobile communication system.
