With the development of wired and wireless communication technology, a variety of communication services supporting multimedia communication have been diversified. In particular, as the data transmission speed is gradually improved, the amount of multimedia data that can be transmitted and received through wired and wireless communication is increasing.

Quality of Service (QoS) refers to various technologies and concepts that manage limited network resources by differentiating service levels according to importance for users or applications.

Conventionally, as a method of efficiently distributing network resources, QoS is set by checking the importance of a user or an application of a communication terminal on the communication network side. In this case, there is a problem that even if a small amount of data is transmitted, basic QoS is set and network resources are wasted.

In addition, since uplink QoS and downlink QoS cannot be set differently, the downlink QoS is set to be the same according to the uplink QoS even for a service mainly used for uplink such as multimedia message transmission. Therefore, there is a problem that downlink QoS is set more than necessary and network resources are wasted.

1 is a configuration diagram schematically showing a system for setting QoS between a communication terminal and a communication network according to an embodiment of the present invention.

Referring to FIG. 1, the system includes a communication terminal 100, a wireless access network 110, a packet controller 120, and a packet data service node 130.

A radio access network (RAN) 110 for transmitting / receiving packets with the communication terminal 100 through a wireless channel and a wireless connection capable of wireless connection is included. The wireless access network 110 may be a base station system (BBS) according to a communication network.

In addition, the system connects the wireless access network 110 and a packet data service node (PSDN) 130 and connects the packet data service node 130 to provide a packet data service and a voice service. A packet data service for connecting a packet control function (PCF) 120 to control and the communication network 140 with the packet controller 120, and providing a packet data service and a voice service to the mobile terminal 100. Node 130 is further included.

In order to set up QoS in the system as described above, the mobile terminal 100 uploads a QoS request for a specific service and packet filtering information to the AN / PDSN 110/130, and then a packet transmitted from the network is transmitted. If received, it performs the actual QoS setting procedure for the service.

2 is a block diagram showing a configuration of a communication terminal according to an embodiment of the present invention.

Referring to FIG. 2, the communication terminal 100 includes a data measuring unit 210, a QoS information generating unit 220, a transmitting and receiving unit 230, an input unit 240, a storage unit 250, a control unit 260, and the like. Include.

The data measuring unit 210 measures the amount of data uploaded to the communication network. In order to adjust the QoS set according to the amount of data, it is to set the corresponding QoS when uploading a small amount of data.

The uploaded data may be, for example, the amount of multimedia file included in the multimedia message transmission. That is, since a multimedia message including a video has a larger capacity than a multimedia message including a text, a corresponding QoS for each case may be set.

The QoS information generation unit 220 performs a function of generating QoS change information requested by the communication terminal 100 to the communication network.

In this specification, the QoS change information is information for changing and setting the QoS which is already set. According to an embodiment of the present invention, the QoS change information may be generated according to the amount of data uploaded to the communication network. According to an embodiment, the communication terminal 100 may be generated according to the type of communication service performed by the communication terminal 100.

The QoS change information generated by the QoS information generation unit 220 may be a data transmission speed, a traffic class, a maximum bandwidth, and the like, and the type of the QoS change information is irrelevant.

Among the QoS information, a traffic class is classified into four types: a conversational class, a streaming class, an interactive class, and a background class.

Each class has different delay sensitivities associated with each of the different classes. For example, the interactive service class is the best lazy dependent service class and the background class is the best lazy independent service class.

Since the traffic class should use a class corresponding to the communication service performed in the communication terminal 150, the QoS change information may include information for changing the type of traffic class.

First, the case where QoS change information is generated according to the amount of data uploaded to the communication network will be briefly described.

The QoS information generator 220 generates QoS change information suitable for transmitting the data amount measured by the data measurer 210. The QoS change information may be generated by a predetermined formula using the amount of data as a variable, and is generated by reading QoS change information according to a classification of the amount of data stored in advance from the storage unit 250 (described later in detail in FIG. 4). can do.

A case where QoS change information is generated according to a communication service type to a communication network according to another embodiment of the present invention will be briefly described.

The QoS information generation unit 220 generates QoS change information suitable for the type of communication service. As long as the communication service is a service that can be provided by the communication terminal, such as wireless Internet access, multimedia message transmission, and video call, the type thereof is irrelevant.

QoS change information according to the type of communication service is stored in advance in the storage unit 250, it may be generated by reading the QoS change information stored in the QoS information generation unit 220.

It may be set by a preset value, a description thereof will be described later in more detail with reference to FIG.

In addition, the QoS information generation unit 220 may generate different uplink QoS change information and downlink QoS change information, respectively.

For convenience of understanding and explanation of the present invention, a description will be given on the assumption of sending a multimedia message. In the multimedia message originating terminal, the amount of data to be downloaded is very small compared to the amount of data to be uploaded. Therefore, more resources can be allocated to the uplink QoS for sending data, and less resources can be allocated to the downlink QoS.

As described above, if the uplink QoS and the downlink QoS are asymmetrically set, there is an advantage in that QoS can be set more efficiently according to the type of communication service, thereby preventing waste of network resources.

The transceiver 230 requests a communication network for QoS setting corresponding to the QoS change information generated by the QoS information generating unit 220 and receives a response to the QoS setting request from the communication network.

If the transceiver 230 is a means for wireless communication connected to the communication network, the type is irrelevant, and may include an antenna in the transceiver 230, and may include a modulator and a transmission amplifier for transmission. In addition, it is apparent to those skilled in the art that it may include a demodulator for receiving and a receive amplifier.

The input unit 240 receives a type of communication service performed by the communication terminal 100. The selection of the communication service is generally selected by the user of the communication terminal 100.

When the input unit 240 receives the communication service of the multimedia message transmission from the user, the QoS information generation unit 220 generates the QoS change information corresponding to the multimedia service and requests that the communication network be set to change to the corresponding QoS.

For example, the input unit 120 may be implemented as a plurality of key buttons including numbers / characters or the like, or may be implemented in the form of a touch screen.

The storage 250 may store data related to a communication service, an operation program of the communication terminal 100, a set algorithm, and the like under the control of the controller 260.

In addition, the storage unit 250 included in the communication terminal 100 according to the present invention may store QoS change information. The QoS change information may be stored according to the classification of the data amount and may be stored according to the type of communication service. The QoS change information stored in the storage unit 250 may be generated as QoS change information read by the QoS information generation unit 220 and requested to the communication network.

Obviously, the manner in which the QoS change information stored in the storage unit 250 is stored may be implemented in various ways.

The controller 260 is a component included in the communication terminal (for example, the data measuring unit 210, the QoS information generating unit 220, the transmitting and receiving unit 230, the input unit 240 and the storage unit 250) Etc.) to generate and output a control signal for controlling.

For example, the controller 260 may control the data measuring unit 210 to measure the amount of data uploaded to the communication network, and generate QoS change information according to the amount of data measured by the data measuring unit 210. The QoS information generation unit 220 may be controlled to make the QoS information generation unit 220.

As described above, the QoS change information in the QoS information generation unit 200 may be generated using a value previously stored in the storage unit 250.

In addition, the controller 260 may control to request a QoS setting corresponding to the QoS change information generated by the QoS information generator 220 to the communication network. This is for efficiently distributing network resources by setting an appropriate QoS according to the amount of data to be transmitted from the communication terminal 100 or the type of communication service to be performed.

In addition, the controller 260 may control to set the QoS between the communication terminal 100 and the communication network by receiving a response to the QoS setting requested to the communication network.

For convenience of understanding and explanation of the present invention, it is assumed that the communication terminal 100 generates QoS change information according to the amount of uploaded data and requests a corresponding QoS setting from the communication network. It is assumed that the multimedia message to which the file is attached is assumed.

In the above example, the data measuring unit 210 measures the amount of the multimedia message including the capacity of the video file attached to the multimedia message. The capacity of the video file may be stored in a specific field in the video file, and the data measuring unit 210 may recognize and measure it.

The QoS information generator 220 generates QoS change information according to the amount of data measured by the data measurer 210. The QoS setting request corresponding to the QoS change information generated by the control of the control unit 260 is requested to the communication network. The QoS setting request is a QoS setting request that can transmit a multimedia message to which a corresponding video file is attached, and excessive QoS is required. It is enough to not waste network resources according to configuration.

The transceiver 230 receives a response to the QoS setting request from the communication network, and the QoS is set between the communication terminal 100 and the communication network to the extent that the multimedia message to which the video file is attached can be transmitted under the control of the controller 260. do.

In FIG. 2, the data measuring unit 210, the QoS information generating unit 220, and the control unit 260 are represented as independent components. However, this is for convenience of description and may be implemented in one circuit. Do.

3 is a flowchart illustrating a QoS setting process between a communication terminal and a communication network according to an embodiment of the present invention.

First, the QoS information generation unit 220 of the communication terminal 100 performs a process of generating QoS change information (step S310). According to the present invention, the QoS information generating unit 220 may be generated according to the amount of data uploaded by the method for generating QoS change information, and may be generated according to the type of communication service performed by the communication terminal 100. Is as described above.

Although not shown in FIG. 3, when QoS change information is generated according to the amount of uploaded data, measuring the amount of uploaded data before step S310 may be performed.

In addition, although not shown in FIG. 3, when QoS change information is generated according to the type of communication service performed by the communication terminal 100, the type of service to be performed through the input unit 240 is input before step S310. The receiving step can be performed.

In addition, in step S310, the uplink QoS change information and the downlink QoS change information may be generated differently from each other. In the case of a communication service mainly using the uplink, as described above, it is possible to efficiently distribute network resources by setting downlink QoS less.

Thereafter, the process proceeds to step S320 and the communication terminal 100 performs a QoS setting request corresponding to the QoS change information to the communication network 140 under the control of the controller 260. Since the transmission of the QoS setting request signal is performed by the transceiver 230, a detailed description thereof will be omitted.

Thereafter, the communication network 140 performs a basic QoS authentication procedure for the QoS setting request requested from the communication terminal 100 (step S330).

In step S340, a response message for establishing an authenticated QoS is transmitted to the communication terminal 100. The response message is a response to the QoS setting requested by the communication terminal 100.

Subsequently, the process proceeds to step S350 and the QoS is set between the communication terminal 100 and the communication network 140 by the control of the control unit 260 of the communication terminal 100 to be in a state capable of transmitting a packet for data communication.

4 is an exemplary diagram illustrating an example in which QoS change information is stored in a storage unit according to an amount of uploaded data according to an embodiment of the present invention.

FIG. 4 illustrates an example in which QoS change information is stored according to the amount of data uploaded, and an example of a terminal capable of using an HSDPA dedicated channel (CH) and an R3 (release 3) terminal using a general channel is provided. An example of the data transmission rate is shown.

That is, the storage in the form of a table shown in FIG. 4 is just one example, and the type of the terminal may be changed in various ways, and stored in the storage unit 250 according to other QoS information in addition to the data transmission rate. It is obvious that the data value or type to be converted can be converted.

 In case of a terminal that can use HSDPA dedicated channel, the size of outgoing data should be 16Kbyte or less.If the data transmission speed is Max Kbps for downlink and 64Kbps for uplink, and the size of outgoing data is larger than 16Kbyte. Indicates that downlink data transmission rate should be secured at max Kbps and uplink data transmission rate should be 384 Kbps. In addition, in case of receiving data, only downlink data transmission rate of Max Kbps and uplink data transmission rate of 64Kbps need to be guaranteed regardless of data size.

On the other hand, in the case of the R3 terminal, the data transmission rate according to the data size may be defined differently in case of transmission and reception in the following cases, and the uplink data transmission rate and the downlink data transmission rate may be defined differently.

In the case of outgoing data, if the size of outgoing data is 16Kbyte or less, the uplink data rate and the downlink data rate can be communicated as long as 64Kbps is guaranteed, whereas if it is larger than 16Kbyte, the uplink The data rate indicates 384 Kbps and the downlink data rate indicates 64 Kbps.

Also, in case of reception, uplink data transmission rate is only guaranteed to be 64Kbps regardless of the size of outgoing data, while downlink data transmission rate is 16Kbyte and 96Kbyte. The required downlink data transfer rate varies with the boundary.

More specifically, if the size of the received data is 16Kbyte or less, only 64Kbps is sufficient, while if the size of the received data exceeds 16Kbyte and less than 96Kbyte, the downlink data transfer rate of 128Kbps is sufficient. When the size of the received data exceeds 96 Kbytes, it indicates that a downlink data transmission rate of 384 Kbps is required.

For convenience of explanation and understanding of the invention, for example, it is assumed that an R3 communication terminal transmits a 50 Kbyte multimedia message. In this case, since the uplink data transmission rate is 384 Kbps and the downlink data transmission rate is 64 Kbps in the data transmission rate of the QoS information, the QoS change information generation unit 220 generates information on the QoS change information. Request the corresponding QoS setting to the network.

As such, when QoS is set, there is an advantage in that it does not waste network resources by not excessively setting downlink QoS, which is relatively less required for multimedia message transmission.

In FIG. 4, only an example of a traffic class and a data transmission rate among QoS information according to the amount of data is illustrated, but it is obvious that QoS information such as a maximum bandwidth may also be stored.

Although illustrated in FIG. 4 as being stored in the storage unit 260 in the form of a table, the storage format may be changed in various ways such as a linked list. It is obvious that QoS change information should be stored according to the amount of uploaded data.

5 is an exemplary diagram illustrating an example in which QoS change information is stored in a storage unit according to a type of communication service performed in a communication terminal according to an embodiment of the present invention.

5 shows examples of types of communication services performed in a communication terminal, such as 'browser', 'file upload', 'LMS / MMS originating', 'LMS / MMS receiving', and 'dial-up networking'. An example of a traffic class and a data transmission rate is shown.

That is, the storage in the form of a table shown in FIG. 5 is just one example, and the form stored in the storage unit 250 according to QoS information other than the traffic class and data transmission rate may be converted. It can be obvious.

For convenience of explanation and understanding of the present invention, it is assumed that a communication service for multimedia message transmission is performed in an HSPA communication terminal. In this case, the traffic class is set to the interactive class, the downlink transmission rate is set to "Max kbps", and there is no limit on the maximum transmission rate. The uplink transmission rate is set to "64 kbps" and the uplink transmission rate is limited. It can be seen that.

That is, when the multimedia message is sent, the QoS information generation unit 220 generates the above QoS change information and requests a QoS setting corresponding to the generated QoS change information to the communication network.

As such, when QoS is set, there is an advantage in that network resources can be managed efficiently.

In FIG. 5, only an example of a traffic class and a data transmission rate among QoS information according to the amount of data is illustrated, but it is obvious that QoS information such as a maximum bandwidth may also be stored.

Although FIG. 5 illustrates that the storage unit 260 is stored in the form of a table, the storage format may be changed in various ways, such as a linked list. However, it is obvious that QoS change information according to the type of communication service performed by the communication terminal 100 should be stored.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art that various modifications of the present invention without departing from the spirit and scope of the invention described in the claims below And can be changed.
