Description

SYSTEM AND METHOD FOR RADIO RESOURCE DYNAMIC ALLOCATION FOR DATA TRANSMISSION

The present invention relates to a system and method for dynamically allocating radio resources to transmit data, and more particularly, to a system and method for dynamically allocating radio resources based on a radio wave environment of a wireless terminal to transmit data. It is about.

Since the broadcast service provided to the conventional wireless terminal transmits only a limited channel, there is no room for efficient use of radio resources. However, as the service for transmitting various contents selected by the user such as mobile IP to the wireless terminal has recently increased, the necessity of efficient use of radio resources is increasing.

In a wireless communication network, it is common that the better the propagation environment between the base station and the user terminal is, the less resources can be used with less data. Therefore, intensive transmission of data when the user terminal is located in a better radio wave reception environment or when the load of the communication network is low can reduce the amount of wireless resources required to transmit the same amount of data, thereby increasing the number of users. It can provide a data transmission service to the.

For example, in the case of a channel having the same transmission power, channel bandwidth, and transmission time in a communication system, the resources are generally the same in terms of the communication system. In this case, if the radio signal environment is excellent, 6 bits of information can be transmitted in one signal using 64QAM (quadrature amplitude modulation), but if the radio signal environment is poor, binary phase shift keying (BPSK) is used. One bit of information can be transmitted in one signal.

In addition, when the radio signal environment is very poor, since one bit of information is spread or transmitted, the amount of information transmitted by one signal is excellent when the signal environment is very poor. It can be reduced by 12 to 24 times or more as compared to.

Therefore, there is a need for a technique that can allocate more resources to a wireless terminal in a better signal environment for efficient use of radio resources, thereby enabling a faster transmission of larger amounts of data in terms of communication systems.

The prior art allocates additional radio resources in case of overload due to lack of radio resources, and controls overload by controlling overload by increasing / decreasing the broadcast period according to priority when a broadcast request is continuously received. By controlling the broadcast period, it is possible to effectively control the overload condition generated during the cell broadcast service or to check whether additional allocation of bandwidth to a specific terminal is required, and then additionally allocate resources of a frequency band other than the basic frequency band to the terminal. It proposes a configuration that adaptively adjusts the allocated bandwidth, loads the same data in different frequency bands, produces a diversity effect, and transmits and receives broadcast data using a separate frequency band in common.

In addition, the conventional technology uses a method of adaptively allocating bandwidth and adjusting and controlling the bandwidth based on whether the bandwidth is wasted and the probability of packet loss, thereby ensuring the performance of the system and the quality of communication service required by the user, A configuration of allocating radio resources to a group of transmission / reception units, signaling radio resource allocation to transmission / reception units, and a configuration of grouping user real-time services by adjusting the allocated radio resources based on a voice level state.

This conventional technology discloses a configuration for allocating radio resources, but does not suggest a configuration for efficiently utilizing radio resources by using different amounts of data transmitted according to the radio wave environment as described above. .

According to an embodiment of the present invention, by allocating a large amount of radio resources to a few radio resources based on a radio wave reception environment, a system capable of efficiently using radio resources by allocating more radio resources to a radio terminal having a high data rate. And to provide a method.

As a technical means for achieving the above-described technical problem, a first aspect of the present invention is a radio wave reception environment determination unit for determining a radio wave reception environment of a wireless terminal that is the target of the data transmission, the determined radio wave reception environment than a predetermined standard In the preferred case, the transmission state setting unit sets the transmission state of the wireless terminal to the concentrated transmission state, and sets the transmission state of the wireless terminal to the general transmission state when the determined radio wave reception environment is worse than the predetermined criterion. And a radio resource allocating unit for allocating a radio resource corresponding to the centralized transmission state to a wireless terminal that is the target of transmission, wherein the wireless resource allocated to the centralized transmission state is larger than the radio resource allocated to the general transmission state. It is possible to provide a radio resource dynamic allocation system.

In a first aspect of the present invention, the transmission state setting unit may set a transmission state for the wireless terminal based on a result of comparing radio wave reception environments of one or more wireless terminals located within the same coverage.

In addition, in the first aspect of the present invention, when the state of the radio wave reception environment of the radio terminal is less than or equal to a preset reference compared to the state of the radio wave reception environment of one or more radio terminals located within the same coverage, the transmission state setting unit The transmission state of the terminal may be set to a general transmission state.

A second aspect of the invention relates to a method of receiving a data transmission request from a wireless terminal within coverage, comparing a radio wave reception environment of the wireless terminal with a radio wave reception environment of one or more other wireless terminals within the coverage and the wireless Allocating a preset radio resource for the centralized transmission of data to the wireless terminal when the level of the radio wave reception environment of the terminal is greater than or equal to a preset level; When the level of the radio wave reception environment of the terminal is greater than or equal to a predetermined level, it is possible to provide a radio resource dynamic allocation method for data transmission that is larger than a radio resource allocated to the radio terminal for data transmission.

According to the above-described problem solving means of the present invention, by increasing the data transmission rate by allocating the radio resources corresponding to the concentrated transmission state to the wireless terminal having a radio wave reception environment of a certain level or more to improve the data rate, It can be transmitted within a short time.

Throughout the specification, when a part is "connected" to another part, this includes not only "directly connected" but also "electrically connected" with another element in between. . In addition, when a part is said to "include" a certain component, which means that it may further include other components, except to exclude other components unless otherwise stated.

1 is a flowchart illustrating a flow of a radio resource dynamic allocation method for data transmission according to an embodiment of the present invention.

In step S105, the wireless terminal located within the coverage of the base station is detected. Since the wireless terminal moves to the coverage of the current base station in another coverage or transmits a signal with the base station by turning on the power at the current coverage, the wireless terminal can detect the wireless terminal by receiving a signal from the wireless terminal.

In step S110, the transmission state of the wireless terminal detected in step S105 is set to the standby state. The wireless terminal set to the standby state is allocated only the minimum resources necessary for transmitting basic signals such as a signal including information of the wireless terminal, a request signal such as data, or the like to the base station.

In step S115, a data transmission request is received from the wireless terminal set to the standby state in step S110. Data targeted for the transmission request may include content data such as video data and audio data, and the transmission method may include a buffering method of a stream.

In step S120, in response to the data transmission request received in step S115, the transmission state of the wireless terminal is set to the normal transmission state. The wireless terminal set to the normal transmission state is allocated only basic radio resources necessary to receive the requested data. The size of the basic radio resource allocated in the normal transmission state depends on the type of service provided by the wireless terminal.

For example, when the wireless terminal receives data of video content for a video on demand (VOD) service, a radio resource such that the video content is played without interruption may be allocated to the wireless terminal set to a normal transmission state.

In step (S120) according to an embodiment of the present invention, it has been described that the wireless terminal set to the standby state requests data transmission, and is set to the normal transmission state from the standby state, but this is only an example and is a standby state, general When the wireless terminal set to the transmission state, the concentrated transmission standby state, or the concentrated transmission state requests data transmission, the wireless terminal may be set back to the normal transmission state.

In step S125, it is determined whether the amount of data transmitted to the wireless terminal is less than a preset transmission level threshold. The transmission level threshold is a threshold of a transmission amount of data set to be received by the wireless terminal in the centralized transmission state. Therefore, the transmission level threshold may be a criterion for determining whether to set the wireless terminal to the centralized transmission state or the general transmission state.

In step S130, if it is determined in step S125 that the amount of data transmitted to the wireless terminal is less than the preset transmission level threshold, it is determined whether there is an idle radio resource in the base station responsible for the coverage in which the wireless terminal is located. To judge.

As described above, when the data transmission is requested from the wireless terminal, the wireless terminal set to the standby state is first set to the normal transmission state. Therefore, when all the wireless terminals are set to the standby state or the normal transmission state, there may be idle radio resources in the base station.

In addition, even if some wireless terminals are set to the centralized transmission state according to the size of the radio resources allocated to the wireless terminal set to the centralized transmission state, there may be idle radio resources in the base station.

In step S135, if it is determined that there is no idle radio resource in the base station in step S135, one or more wireless terminals located in the same coverage of the radio wave reception environment of the wireless terminal that requested data transmission in step S115. The level of the radio wave reception environment of the wireless terminal that has requested the data transmission is determined by comparing with the radio wave reception environment of. The radio wave reception environment may be determined according to various factors such as the distance between the base station and the wireless terminal and the type of structure surrounding the wireless terminal.

In step S140, as a result of the comparison in step S135, it is determined whether the level of the radio wave reception environment of the radio terminal which has requested data transmission falls within a preset radio wave reception environment level. That is, it is determined whether the radio wave reception environment of the radio terminal that has requested data transmission is superior enough to allocate radio resources intensively compared to other radio terminals.

The radio wave reception environment level may be determined by evaluating the radio wave reception environment of the wireless terminal in an absolute or relative manner. For example, in the case of relatively determining the radio wave reception environment, by comparing the state of the radio wave reception environment of the radio terminal which requested data transmission with the state of the radio wave reception environment of another radio terminal, the ranking is determined based on the goodness of the state. The radio wave reception environment level can be determined.

In this case, the preset level may be changed according to the size of the radio resource to be allocated. For example, when all the radio resources for centralized transmission are allocated to one wireless terminal, the preset priority may be 1st. In addition, when allocating radio resources for intensive transmission to 10 wireless terminals, the predetermined rank may be 10 rank.

In step S145, when the ranking of the superiority of the radio wave reception environment of the wireless terminal does not correspond to the predetermined rank in step S140, the transmission state of the wireless terminal is set to the concentrated transmission standby state.

Even if it is set to the centralized transmission standby state, the wireless terminal may be allocated radio resources of the same size as the normal transmission state and thus may continue to receive the data requested in step S115.

Therefore, in some cases, when the ranking of the superiority of the radio wave reception environment of the wireless terminal does not correspond to the preset ranking in step S140, it is omitted to set the transmission state of the wireless terminal to the centralized transmission standby state and the general transmission state. Can be maintained.

In step S150, when the rank of the superiority of the radio wave reception environment of the wireless terminal corresponds to a preset rank in step S140, the transmission state of the wireless terminal is set to the centralized transmission state.

The wireless terminal set to the centralized transmission state is allocated more radio resources compared to the radio resources allocated when it is set to the normal transmission state, and the allocated radio resources allow more data to be sent more quickly than in the normal transmission state. Can be received.

In step S155, it is determined whether the amount of data transmitted to the wireless terminal set to the concentrated transmission state in step S150 is less than a preset transmission level threshold.

The comparison between the transmission amount of data transmitted to the wireless terminal and the preset transmission level threshold is performed after a predetermined time has elapsed after the wireless terminal is set to the centralized transmission state, or at the same time the data transmission amount and the transmission level threshold while transmitting data. Can be compared.

As described above, the transmission level threshold may be a criterion for determining whether to set the wireless terminal to the centralized transmission state or the general transmission state. This transmission level threshold may be set, for example, to 80 to 90 percent (%), or 100 percent of the total data.

In step S160, when it is determined in step S155 that the amount of data transmitted to the wireless terminal is greater than or equal to a preset transmission level threshold, the transmission state of the wireless terminal is set to the normal transmission state. As described above, the wireless terminal set to the normal transmission state is allocated only the minimum resources necessary to receive the requested data.

In step S165, the wireless terminal receives all the data requested in step S115 to determine whether the transmission of data to the wireless terminal is completed.

In step S170, when it is determined in step S165 that data transmission is completed, the transmission state of the wireless terminal where data transmission is completed is set to a standby state.

2 is a diagram illustrating a transition of a transmission state in which a wireless terminal is set in a method for dynamically allocating a radio resource for data transmission according to an embodiment of the present invention.

When the wireless terminal is located within the coverage of the base station, the transmission state of the wireless terminal is set to the standby state 10. As described above, the standby state is a state in which the wireless terminal is assigned only the minimum resources necessary for transmitting and receiving signals with the base station.

When the wireless terminal requests the transmission of data, the transmission state of the wireless terminal is changed from the standby state 10 to the normal transmission state (S11). As described above, the general transmission state 20 is a state in which the wireless terminal is assigned only the minimum resources necessary for receiving the request data.

When the radio wave reception environment of the wireless terminal set to the general transmission state 20 is higher than or equal to a preset level, the transmission state of the wireless terminal is changed from the general transmission state 20 to the concentrated transmission state 40 (S21). The centralized transmission state 40 is a state in which a greater amount of radio resources are allocated than a radio resource allocated in the normal transmission state in order to receive the data requested by the radio terminal within a shorter time.

In addition, when the radio wave reception environment of the wireless terminal set to the general transmission state 20 is less than the preset level, the transmission state of the wireless terminal is changed from the general transmission state 20 to the concentrated transmission standby state 30 (S22). In the centralized transmission wait state 30, the wireless terminal is allocated a radio resource of the same size as the normal transmission state. In the concentrated transmission standby state 30, the radio wave reception environment of the wireless terminal is analyzed at predetermined intervals or simultaneously with data transmission for changing to the concentrated transmission state 40. FIG.

When data transmission to the wireless terminal set to the normal transmission state 20 is terminated, the transmission state of the wireless terminal is changed from the normal transmission state 20 to the standby state 10 (S23). The termination of the data transmission may be caused by completion or interruption of the data transmission.

When the radio wave reception environment of the wireless terminal set to the concentrated transmission standby state 30 is equal to or higher than a preset level, the transmission state of the wireless terminal is changed from the concentrated transmission standby state 30 to the concentrated transmission state 40 (S31).

When data transmission from the concentrated transmission standby state 20 to the wireless terminal is terminated, the transmission state of the wireless terminal is changed from the concentrated transmission standby state 30 to the standby state 10 without passing through the concentrated transmission state 40. (S32).

When the radio wave reception environment of the wireless terminal set to the centralized transmission state 40 deteriorates to less than a predetermined level, the transmission state of the wireless terminal may be changed to the centralized transmission standby state 30. However, when data transmission is terminated while the radio wave reception environment of the wireless terminal is maintained above a predetermined level, the transmission state of the wireless terminal is changed from the concentrated transmission state 40 to the standby state 10.

As such, the transmission state of the wireless terminal may be changed according to the radio wave reception environment of the wireless terminal and whether data transmission is terminated.

FIG. 3 is a diagram illustrating the size of a radio resource allocated to a wireless terminal according to a radio wave reception environment and a transmission state of the wireless terminal within coverage in a radio resource dynamic allocation system for data transmission according to an embodiment of the present invention. .

In FIG. 3, the wireless terminal 300 receives data from the base station 400 while moving the coverage 410 of the base station 400 along the movement path 420 from the point A1 to the point A6.

At point A1, wireless terminal 300 enters coverage 410 and the resource allocation system detects that wireless terminal 300 is located within coverage 410. The resource allocation system sets the transmission state of the wireless terminal 300 to the standby state 10 and allocates the radio resource 11 accordingly to the wireless terminal 300.

At point A2, the wireless terminal 300 requests the transmission of data, and the resource allocation system sets the transmission state of the wireless terminal 300 to the general transmission state 20 in response to the data transmission request. In this regard, the wireless terminal 300 is allocated a basic radio resource 21 necessary for data reception.

At the point A3, the resource allocation system determines that the analyzed radio wave reception environment of the wireless terminal 300 is less than a preset level, and sets the transmission state of the wireless terminal 300 to the centralized transmission standby state 30. In the centralized transmission standby state 30, the wireless terminal may be allocated a basic radio resource 21.

At the point A4, when the radio wave reception environment of the wireless terminal 300 is above a preset level as the position of the wireless terminal 300 approaches the base station, the resource allocation system concentrates the transmission state of the wireless terminal 300. The radio resource 41 according to the centralized transmission is allocated to the radio terminal 300. As more radio resources are allocated to the wireless terminal 300, the data transmission rate to the wireless terminal 300 increases, thereby increasing the data transmission rate.

At the point A5, when the data transmission to the wireless terminal 300 is finished, the resource allocation system sets the transmission state of the wireless terminal 300 to the standby state 10, and accordingly the radio resource 11 is set to the wireless terminal 300. Is assigned to).

As such, the resource allocation system intensively allocates radio resources to the radio terminal 300 that has requested data transmission based on the radio wave reception environment so that data transmission can be efficiently performed.

In the above-described example, the radio wave reception environment has been described as changing according to the distance between the wireless terminal 300 and the base station 400, but is not limited to this, as well as the wireless distance between the wireless terminal 300 and the base station 400, The radio wave reception environment may change according to the surrounding environment of the terminal 300. For example, when located in an environment where radio waves are blocked, the radio wave reception environment of the wireless terminal 300 may be deteriorated.

The resource allocation system 100 according to an embodiment of the present invention includes a signal receiver 110, a radio wave reception environment determiner 120, a transmission state setting unit 130, and a radio resource allocator 140.

The signal receiver 110 receives information on a data transmission state from the data providing server 200 transmitting the requested data to the wireless terminal 300. In addition, the signal receiver 110 receives a signal from the wireless terminal 300 including information on the wireless terminal 300, for example, information such as a radio wave reception environment.

The radio wave reception environment determiner 120 extracts data of the radio wave reception environment from the information of the radio terminal 300 received from the signal receiver 110, and determines the radio wave reception environment level of the radio terminal 300.

The radio wave reception environment determination unit 120 may determine the radio wave reception environment level of the radio terminal 300 using, for example, the amount of data transmitted to the radio terminal by the same signal.

The transmission state setting unit 130 according to the level of the radio wave reception environment of the radio terminal 300 determined by the radio wave reception environment determination unit 120 and the information about the amount of data transmission received from the signal reception unit 110 may be used. Set the transmission state of 300).

The transmission state setting unit 130 may set the transmission state of the wireless terminal 100 to any one of a standby state, a general transmission state, a concentrated transmission standby state, or a concentrated transmission state.

The standby state is a state in which the wireless terminal waits to transmit a signal to or receive a signal from the base station, and the wireless terminal set to the standby state is allocated only the minimum radio resources necessary for waiting for signal transmission and reception.

The normal transmission state is a state in which a wireless terminal receives data by using basic radio resources allocated thereto and receives a service. The wireless terminal set to the normal transmission state is allocated a basic radio resource for providing a service, and the radio resource allocated to the wireless terminal may be different according to the type of service provided.

In the concentrated transmission standby state, when the radio wave reception environment of the wireless terminal is less than a predetermined level, it is a state for determining whether the concentrated transmission to the wireless terminal is possible by analyzing the transmission environment state of the wireless terminal periodically or continuously.

The wireless terminal set to the centralized transmission standby state may receive the same radio resource as the normal transmission state and receive data.

In the centralized transmission state, when the radio wave reception environment of the wireless terminal is higher than or equal to a preset level, the wireless terminal allocates more radio resources to the wireless terminal to perform data transmission quickly.

In the centralized transmission state, since data is transmitted through a larger amount of radio resources in a more suitable environment for data transmission, more efficient data transmission can be performed than in the normal transmission state.

The radio resource allocator 140 allocates the radio resource preset to the radio terminal 300 according to the transmission state set by the transmission state setting unit 130.
