GPRS 단말기의 데이터 송수신방법{TRANSMISSION/RECEPTION METHOD FOR DATA OF GPRS TERMINAL EQUIPMENT}TRUSMISSION / RECEPTION METHOD FOR DATA OF GPRS TERMINAL EQUIPMENT}

본 발명은 GPRS(General Packet Radio Service) 단말기의 데이터 송수신방법에 관한 것으로, 특히 패킷 채널 요구 또는 채널요구 비트에 랜덤비트를 최고속도로 셋팅하여 기지국으로부터 최고속도에 해당하는 채널을 할당받아 최고속도의 데이터 송수신이 가능하도록 한 GPRS 단말기의 데이터 송수신방법에 관한 것이다.The present invention relates to a method for transmitting and receiving data of a general packet radio service (GPRS) terminal, and in particular, by setting a random bit at a maximum speed in a packet channel request or channel request bit, a channel corresponding to the highest speed is allocated from a base station to receive the highest speed data. The present invention relates to a method for transmitting and receiving data of a GPRS terminal.

일반적으로, GPRS시스템에서 채널 할당은 RADIO PRIORITY를 고려한 셀의 상태에 따라 네트워크(N/W)에 의해 이루어진다.In general, in the GPRS system, channel allocation is performed by the network (N / W) according to the state of a cell considering RADIO PRIORITY.

현 GPRS 단말기는 셀 상황에 따라 망에서 내려주는 대로 타임슬롯을 할당 받아 데이터를 송수신한다.The current GPRS terminal receives and assigns a time slot to transmit and receive data according to cell conditions.

그러나, 상기와 같이 동작하는 종래 기술의 GPRS시스템에서는 셀 상황에 따라 망에서 내려주는 대로 타임슬롯을 할당 받을 수 밖에 없기 때문에 셀에 사용자가 많은 경우에는 급하게 전송할 데이터를 가지고 있거나 비싸더라도 좀더 빠른 송수신을 원하는 사용자를 배려할 수 없었다.However, in the GPRS system of the prior art that operates as described above, the time slots are allocated as they are dropped from the network according to the cell situation. I couldn't care about the users I wanted.

본 발명은 상기와 같은 문제점을 해결하기 위하여 창안한 것으로, 사용자에 의해 강제로 GPRS 단말기를 통해 데이터를 송수신하고자 할때, 옵션중 최고속도를 선택하게 되면, 패킷 채널요구 혹은 채널요구 메시지에 있는 랜덤비트를 최고속도로 셋팅하여 기지국이 사용자가 최고속도에 해당하는 채널을 할당받기를 원하고 있다는것을 알 수 있도록 하였다.The present invention has been made to solve the above problems, when the user is forced to send and receive data through the GPRS terminal, when selecting the maximum speed of the option, the random in the packet channel request or channel request message By setting the bit to the maximum speed, the base station knows that the user wants to be assigned the channel corresponding to the maximum speed.

이 경우 기지국은 GPRS 단말기의 종류를 확인한 다음, 여기에 해당하는 최대의 채널을 할당하게 된다. 또한 채널 할당후 데이터 전송이 빨리 진행될 수 있도록 한다. 이렇게 해서 사용자의 입장에서는 많은 채널을 점유하여 빠른 속도의 데이터 송수신이 가능하도록 한 GPRS 단말기의 데이터 송수신방법을 제공함에 그 목적이 있다.In this case, the base station checks the type of the GPRS terminal, and then allocates the maximum channel corresponding thereto. In addition, data transfer can be performed quickly after channel allocation. In this way, the user's point of view is to provide a data transmission / reception method of a GPRS terminal that enables a high speed data transmission and reception by occupying many channels.

상기와 같은 목적을 달성하기 위한 본 발명은, 사용자가 원하는 속도로 네트워크와 데이터를 송수신하는 GPRS 단말기에 있어서, 패킷 채널요구 메시지의 8비트 혹은 11비트의 액세스 버스트중 2개 또는 3개의 랜덤비트를 사용자가 선택한 데이터의 송수신속도로 변환하여 송수신 속도를 네트워크에게 알리는 제1 단계와; 상기 패킷 채널요구 메시지를 수신한 네트워크는 상기 2개 또는 3개의 랜덤비트가 최대 또는 표준속도인가를 확인하고, 그에 따라 네트워크와 GPRS 단말기간 송수신 속도의 타임슬롯을 할당하여 GPRS 단말기와 네트워크간에 데이터 전송을 수행하는 제2 단계로 이루어진 것을 특징으로 한다.In order to achieve the above object, the present invention provides a GPRS terminal that transmits and receives data to and from a network at a speed desired by a user, and includes two or three random bits of an 8-bit or 11-bit access burst of a packet channel request message. A first step of informing a network of a transmission / reception rate by converting to a transmission / reception rate of data selected by a user; The network receiving the packet channel request message checks whether the two or three random bits are at the maximum or standard speed, and allocates a time slot of transmission / reception rate between the network and the GPRS terminal and transmits data between the GPRS terminal and the network. Characterized in that the second step of performing.

이하, 본 발명에 따른 일실시예를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명 GPRS(General Packet Radio Service) 단말기의 데이터 송수신방법을 보인 흐름도로서, 이에 도시된 바와 같이 사용자가 원하는 속도로 네트워크와 데이터를 송수신하는 GPRS 단말기에 있어서, 패킷 채널요구 메시지의 8비트 혹은 11비트의 액세스 버스트중 2개 또는 3개의 랜덤비트를 사용자가 선택한 데이터의 송수신속도로 변환하여 송수신 속도를 네트워크에게 알리는 제1 단계와; 상기 패킷 채널요구 메시지를 수신한 네트워크는 상기 2개 또는 3개의 랜덤비트가 최대 또는 표준속도인가를 확인하고, 그에 따라 네트워크와 GPRS 단말기간 송수신 속도의 타임슬롯을 할당하여 GPRS 단말기와 네트워크간에 데이터 전송을 수행하는 제2 단계로 이루어진 것으로, 이와 같이 구성된 본 발명의 동작을 설명하면 다음과 같다.1 is a flowchart illustrating a data transmission / reception method of a general packet radio service (GPRS) terminal of the present invention. As shown in FIG. 1, 8 bits of a packet channel request message in a GPRS terminal transmitting and receiving data to and from a network at a desired speed as shown in FIG. Or a first step of converting two or three random bits of an 11-bit access burst into a transmission / reception rate of data selected by a user to inform the network of the transmission / reception rate; The network receiving the packet channel request message checks whether the two or three random bits are at the maximum or standard speed, and allocates a time slot of transmission / reception rate between the network and the GPRS terminal and transmits data between the GPRS terminal and the network. The operation of the present invention configured as described above consists of a second step of performing the following.

먼저, 사용자는 GPRS 단말기 표시창에 지금 전송하고자 하는 데이터를 어떻게 전송할 것인지 선택한다.First, the user selects how to transmit the data to be transmitted on the GPRS terminal display window.

상기 GPRS 단말기의 표시창에 표시되는 데이터 전송속도는 다운링크(Downlink)의 표준속도/최고속도(Normal Speed/Full Speed), 업링크(Uplink)의 표준속도/최고속도(Normal Speed/Full Speed)로 표시된다.The data transmission speed displayed on the display window of the GPRS terminal is the standard speed / full speed of the downlink and the normal speed / full speed of the uplink. Is displayed.

이때, GPRS 단말기는 사용자가 좀 더 빠른 전송을 위해 최고속도(Full Speed)를 선택하면 패킷 채널을 요구할때 랜덤비트에 이와 같은 상황을 반영시킨다.In this case, when the user selects a full speed for faster transmission, the GPRS terminal reflects such a situation in a random bit when requesting a packet channel.

즉, 패킷 채널요구(Packet Channel Request)신호는 망의 규정에 따라 8비트 혹은 11비트 액세스 버스트(Access Burst)로 구성되며 8비트의 경우는 2개, 11비트의 경우는 3개의 랜덤 비트(Random Bits)를 가지게 된다.That is, the packet channel request signal is composed of 8-bit or 11-bit access bursts according to the regulations of the network, and 2 random bits (8 bits) and 3 random bits (11 bits). Bits).

도 2는 이러한 패킷 채널요구신호의 8비트, 11비트의 랜덤비트를 보인 예시도로서, 먼저 11비트의 액세스 버스트(Access Burst)인 경우 9번째 비트는 임의의 값(Random Value)을 가지고, 10번째 비트는 다운링크의 속도로 '0'은 표준속도, '1'은 최고속도를 나타내며 11번째 비트는 업링크의 속도로 '0'은 표준속도, '1'은 최고속도를 나타낸다.FIG. 2 is an exemplary diagram showing random bits of 8 and 11 bits of the packet channel request signal. In the case of an 11-bit access burst, the ninth bit has a random value. The first bit is the downlink speed, '0' is the standard speed, '1' is the maximum speed, the 11th bit is the uplink speed, '0' is the standard speed, and '1' is the maximum speed.

8비트의 액세스 버스트(Access Burst)인 경우에는 7번째 비트가 다운링크 속도를 나타내는것으로 '0'은 표준속도, '1'은 최고속도를 나타내며, 8번째 비트는 업링크 속도를 나타내는 것으로 '0'은 표준속도, '1'은 최고속도를 나타낸다.In the case of an 8-bit access burst, the seventh bit represents the downlink speed, '0' represents the standard speed, '1' represents the highest speed, and the eighth bit represents the uplink speed. 'Is the standard speed and' 1 'is the maximum speed.

그러나, 제2 네트워크 모드(Network Mode 2)인 경우에는 상기 패킷 채널요구(Packet Channel Request)신호를 쓰지 못하고 채널요구(Channel Request)신호를 써야한다. 채널요구(Channel Request)신호는 8비트로 구성된 액세스 버스트(Access Burst)이지만 랜덤 비트(Random bit)가 3개이다. 왜냐하면 채널요구(Channel Request)신호를 보낼때의 커즈(cause)가 싱글 블럭 패킷 액세스(Single block packet Access) 이어야만 의미를 가지기 때문이다.However, in the case of the second network mode (Network Mode 2), the packet channel request signal cannot be written and the channel request signal must be used. The channel request signal is an access burst consisting of 8 bits but has 3 random bits. This is because the cause when sending a Channel Request signal is meaningful only when it is a single block packet access.

네트워크는 마지막 비트가 '1'인 즉, 사용자가 최고속도를 원한다고 표시된 패킷 채널요구신호를 수신하면 이동국의 GPRS 단말기의 종류를 확인한 후 할당 가능한 최대 타임슬롯을 할당함과 동시에 데이터 전송이 신속하게 이루어질 수 있도록 한다.When the network receives the packet channel request signal indicating that the last bit is '1', that is, the user wants the highest speed, the network checks the type of the GPRS terminal of the mobile station and allocates the maximum time slot that can be allocated. To help.

이때, 상기 네트워크는 GPRS 단말기로부터 데이터 콜을 수신하면 그 GPRS 단말기의 종류에 따른 최대 다운링크 타임슬롯을 할당함과 아울러, 업링크 속도표시 상태를 저장한다.At this time, when the network receives a data call from the GPRS terminal, the network allocates a maximum downlink timeslot according to the type of the GPRS terminal and stores the uplink speed display state.

이와 반대의 경우로는 상기 네트워크가 GPRS 단말기로부터 데이터 콜을 수신하지 않으면 GPRS 단말기의 종류에 따른 최대 업링크 타임슬롯을 할당함과 아울러, 다운링크 속도표시 상태를 저장한다.On the contrary, if the network does not receive a data call from the GPRS terminal, the network allocates a maximum uplink timeslot according to the type of GPRS terminal and stores the downlink speed indication state.

이상에서 상세히 설명한 바와 같이 본 발명은 사용자에 의해 강제로 GPRS 단말기를 통해 데이터를 송수신하고자 할때, 옵션중 최고속도를 선택하게 되면, 패킷 채널요구 혹은 채널요구 메시지에 있는 랜덤비트를 최고속도로 셋팅하여 기지국이 사용자가 최고속도에 해당하는 채널을 할당받기를 원하고 있다는것을 알 수 있도록 함으로써, GPRS 단말기의 종류에 해당하는 최대속도의 채널을 할당하여 빠른 속도의 데이터 송수신이 가능하도록 하는 효과가 있다.As described in detail above, in the present invention, when a user is forcibly sending and receiving data through a GPRS terminal, when selecting the maximum speed among the options, the random bit in the packet channel request or channel request message is set to the maximum speed. By allowing the base station to know that the user wants to be assigned a channel corresponding to the highest speed, the base station allocates a channel of the maximum speed corresponding to the type of GPRS terminal to enable high speed data transmission and reception.
