Abstract

PURPOSE: A method for receiving a signal in a mobile communication terminal is provided to minimize an idle time zone and improve the receiving rate of the mobile communication terminal by maximally decreasing a slot cycle of the mobile communication terminal in a low electric field area and minimizing an idle period of an RF(Radio Frequency) end alternately operated in sleep and idle states. CONSTITUTION: A mobile communication terminal receives a signal transmitted from a base station, and detects an electric field strength of the received signal. The mobile communication terminal varies a slot cycle according to the electric field strength of the received signal. The mobile communication terminal interworks with the base station in an idle state of the varied slot cycle, and communicates with the base station. If the electric field strength of the received signal is high, the mobile communication terminal increases the slot cycle. If the electric field strength of the received signal is low, the mobile communication terminal decreases the slot cycle.

즉, 기지국의 슬롯 싸이클(Slot Cycle) 인덱스가 '1'이고, 이동통신 단말기의 슬롯 싸이클(Slot Cycle) 인덱스가 '2'라면 이동통신 단말기의 슬롯 싸이클 (Slot Cycle) 인덱스는 기지국의 슬롯 싸이클(Slot Cycle) 인덱스 '1'을 따라 동작하게 된다.That is, when the slot cycle index of the base station is '1' and the slot cycle index of the mobile communication terminal is '2', the slot cycle index of the mobile communication terminal is the slot cycle (the base station). Slot Cycle) is operated along the index '1'.

여기서, 상술한 이동통신 단말기의 슬롯 싸이클(Slot Cycle) 인덱스의 동작은 수신전계강도에 무관하게 기지국과 단말기 사이의 슬롯 싸이클(Slot Cycle) 인덱스 중 작은 슬롯 싸이클(Slot Cycle) 인덱스로 동작하게 되어 있어, 약전계 지역에서의 수신감도가 저하되는 문제점이 있다.Here, the operation of the slot cycle (Slot Cycle) index of the mobile communication terminal described above is operated as a small slot cycle (Slot Cycle) index of the slot cycle (Slot Cycle) index between the base station and the terminal regardless of the received field strength.

The purpose is to provide.

도2는 도1에 있어서, 슬롯 싸이클에 대한 파형도.2 is a waveform diagram of a slot cycle in FIG.

상기와 같은 목적을 달성하기 위한 본 발명은, 기지국으로부터 송출되는 신호를 수신하여 그 수신신호의 전계강도를 검출하는 제1 과정과; 상기 수신신호의 전계강도에 따라 슬롯 싸이클(Slot Cycle)을 가변하는 제2 과정과; 상기 가변된 슬롯 싸이클(Slot Cycle)의 아이들(Idle) 상태에서 기지국과 연동하여 서로 통신하는 제3 과정으로 수행함을 특징으로 한다.The present invention for achieving the above object comprises a first step of receiving a signal transmitted from the base station and detecting the electric field strength of the received signal; A second process of varying a slot cycle according to the electric field strength of the received signal; And performing a third process of communicating with each other in cooperation with a base station in an idle state of the variable slot cycle.

이하, 본 발명에 의한 이동통신단말기의 신호 수신방법에 대한 작용 및 효과를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the operation and effects of the signal receiving method of the mobile communication terminal according to the present invention will be described in detail.

도1은 본 발명 이동통신단말기의 신호 수신방법에 대한 동작 흐름도로서, 이에 도시한 바와같이 실험에 의해, 수신전계강도에 따라 적용되는 해당 슬롯 싸이클 (Slot Cycle)을 기설정하는 제1 과정과; 기지국으로부터 송출되는 신호를 수신하여 그 수신신호의 전계강도를 검출하는 제2 과정과; 상기 수신신호의 전계강도에 따라 슬롯 싸이클(Slot Cycle)을 가변하는 제3 과정과; 상기 가변된 슬롯 싸이클(Slot Cycle)의 아이들(Idle) 상태에서 기지국과 연동하여 서로 통신하는 제3 과정으로 이루어지며, 이와 같은 본 발명의 동작을 설명한다.1 is an operation flowchart of a signal receiving method of a mobile communication terminal according to the present invention, and as a result, a first process of presetting a corresponding slot cycle applied according to a received electric field strength by experiment; Receiving a signal transmitted from the base station and detecting a field strength of the received signal; A third step of varying a slot cycle according to the electric field strength of the received signal; A third process of communicating with each other in conjunction with the base station in the idle state of the variable slot cycle (Slot Cycle) will be described, the operation of the present invention as described above.

먼저, 실험에 의해, 수신전계 강도에 따라 적용되는 해당 슬롯 싸이클(Slot Cycle)을 기설정한 다음, 기지국으로부터 송출되는 신호를 수신하여 그 수신신호의 전계 강도를 검출한다.First, by experiment, the slot cycle applied according to the received electric field strength is preset, and then the signal transmitted from the base station is received to detect the electric field strength of the received signal.

상기 슬롯 싸이클(Slot Cycle)은, 0~7까지의 슬롯 싸이클(Slot Cycle) 인덱스로 가능한데, 단말기의 1 슬롯(Slot)은 80ms이며 슬롯 싸이클(Slot Cycle) 인덱스가 '0'인 경우, 16*80ms=1.28 sec 마다 슬립(Sleep)에서 깨어나 이이들 상태로 천이된다.The slot cycle is possible with a slot cycle index from 0 to 7, wherein 1 slot of the terminal is 80ms and the slot cycle index is '0', 16 *. Every 80ms = 1.28 sec wakes up and transitions to these states.

만약, 슬롯 싸이클(Slot Cycle) 인덱스가 '2'인 경우에는, 64*80msec =5.12 sec마다 슬립(Sleep)에서 깨어나 아이들(Idle) 상태로 천이되며, 최대인 슬롯 싸이클(Slot Cycle) 인덱스 '7'인 경우 2048 *80msec=163.84sec마다 슬립(Sleep)에서 깨어나 아이들(Idle) 생태로 천이된다.If the slot cycle index is '2', the system wakes up from the sleep every 64 * 80msec = 5.12 sec and transitions to the idle state, and the maximum slot cycle index '7' 'Awakens from sleep every 2048 * 80 msec = 163.84 sec, and transitions to the idle ecology.

상기 아이들(Idle) 상태에서 기지국과 연동하여 서로 통신을 하게 된다.In the idle state, the base station communicates with the base station.

또한, 슬립(Sleep) 및 아이들(Idle) 커런트를 비교하면, 슬립(Sleep) 커런트는 1.5mA정도인데 반하여, 아이들(Idle)시는 110mA정도로 많은 차이를 보인다.In addition, when comparing the sleep and idle currents, the sleep current is about 1.5 mA, while the idle is about 110 mA.

이때, 기지국으로부터 이동통신단말기에 수신되는 신호의 전계강도에 따라 상기 슬롯 싸이클(Slot Cycle)을 가변하는데, 즉, 수신신호의 전계강도가 높으면 슬롯 싸이클(Slot Cycle)을 크게 하고, 수신신호의 전계강도가 낮으면 슬롯 싸이클(Slot Cycle)을 작게 한다.In this case, the slot cycle is varied according to the electric field strength of the signal received from the base station to the mobile communication terminal. That is, if the electric field strength of the received signal is high, the slot cycle is increased and the electric field of the received signal is increased. Lower strengths result in smaller slot cycles.

상기에서, 수신신호의 전계 강도가 낮으면, 슬립(Sleep) 상태와 아이들 (Idle) 상태로 번갈아 동작하는 알에프단의 아이들(Idle) 주기를 최소화하여 아이들(Idle) 상태로 빠지는 시간대를 최대화함으로써 단말기의 수신율을 최대한 향상시킨다.In the above, when the electric field strength of the received signal is low, the terminal by minimizing the idle period of the RF stage operating alternately in the sleep state and the idle state to maximize the time period to fall into the idle state Improves the reception rate to the maximum.

다시 말해서, 본 발명은, 기지국에서 송신되는 신호의 수신전계 강도에 따라, 약전계 지역에서는 슬롯 싸이클(Slot Cycle)을 최대한 작게 하여 슬립(Sleep)/아이들(Idle)을 번갈아 동작하는 RF단의 아이들(Idle) 주기를 최소화함으로써, 아이들(Idle)로 빠지는 시간대를 최대화하여 단말기의 수신율을 최대한 향상시킨다.In other words, according to the present invention, according to the received electric field strength of a signal transmitted from a base station, in the weak field region, the idle cycle of the RF stage operating alternately sleep / idle by making the slot cycle as small as possible. By minimizing the (Idle) cycle, the reception rate of the terminal is improved as much as possible by maximizing the time period falling into the idle (Idle).

상기 본 발명의 상세한 설명에서 행해진 구체적인 실시 양태 또는 실시예는 어디까지나 본 발명의 기술 내용을 명확하게 하기 위한 것으로 이러한 구체적 실시예에 한정해서 협의로 해석해서는 안되며, 본 발명의 정신과 다음에 기재된 특허 청구의 범위내에서 여러가지 변경 실시가 가능한 것이다.The specific embodiments or examples made in the detailed description of the present invention are intended to clarify the technical contents of the present invention to the extent that they should not be construed as limited to these specific embodiments and should not be construed in consultation. Various changes can be made within the scope of.

이상에서 상세히 설명한 바와같이 본 발명은, 약전계 지역에서는 단말기의 슬롯 사이클을 최대한 작게 하여 슬립(Sleep)/아이들(Idle)을 번갈아 동작하는 RF단의 아이들(Idle) 주기를 최소화함으로써, 아이들(Idle)로 빠지는 시간대를 최소화하여 단말기의 수신율을 향상시키는 효과가 있다.As described in detail above, the present invention minimizes idle cycles of the RF stage operating alternately of sleep / idle by minimizing the slot cycle of the terminal in the weak electric field region. By minimizing the time zone to fall by), the reception rate of the terminal is improved.
