The AG 200910813 can be divided into a component for handling user traffic and a component for handling control traffic. At this time, an AG for processing new user services and an AG for processing control services can communicate with each other by using a new interface. An eNode B can have one or more cells. An interface for transmitting user traffic or controlling traffic can be used between the eNode Bs. The CN may include an AG, a node for user registration of other UEs, and the like. The interface between the E-UTRAN and the CN can be distinguished using an interface. The radio interface between the terminal and the network can be based on a lower layer of the Open System Interconnection (OSI) standard model, which is well known in communication systems. The layer is divided into a first layer (L1), a second layer (L2), and a third layer (L3). A physical layer belonging to the first layer provides an information transfer service by using a physical channel. A Radio Resource Control (RRC) layer at the bottom of the third layer controls radio resources between the terminal and the network. To achieve this, the RRC layer allows RRC messages to be exchanged between the terminal and the network. Figures 2 and 3 show a radio interface protocol architecture between a terminal and an E-UTRAN based on the 3GPP radio access network standard. Specifically, Figure 2 shows the radio protocol architecture in a control plane, and Figure 3 shows the radio protocol architecture in a user plane. The radio interface protocol in FIG. 2 and FIG. 3 has a horizontal layer and a vertical plane, and the horizontal layer includes a physical layer, a data link layer, and a _ network layer, and the vertical planes include one for transmission use. The use of the communication service 6 200910813 plane, and a control plane for transmitting control signals. The protocol layers in Figures 2 and 3 can be divided into a first layer (L1) and a second layer (L2) based on a three-layer lower layer of an Open Systems Interconnection (OSI) standard model well known in communication systems. And a third layer (L3)e will be described below for each of the radio protocol control plane in FIG. 2 and the radio protocol user plane in FIG. A layer _ (as a physical layer) provides information transfer services to an upper layer by using a physical channel. The physical layer is connected to its upper layer (called the Medium Access Control (MAC) layer) via a transport channel. The MAC layer exchanges data with the physical layer via the transport channel. The data is transferred via a physical channel between different physical layers (i.e., between the physical layer of a transmitting end and the physical layer of a receiving end). The physical channel is modulated based on Orthogonal Frequency Division Multiplexing (OFDM) technology, and uses time and frequency as radio resources. The MAC layer at the second layer provides services to a layer above the Radio Link Control (RLC) layer via a logical channel. The second layer of the RLC layer supports reliable data transmission. The function of the RLC layer can be implemented in one of the functional blocks in the MAC layer. In this case the 'RLC layer may not be present. A Packet Data Convergence Protocol (PDCP) layer of the second layer in the radio protocol user plane is used to efficiently transport IP packets (such as IPv4 or IPv6) over a radio interface with a relatively narrow bandwidth. . To achieve this, the PDCP layer reduces the size of a jp 200910813 packet header that is relatively large in size and includes unnecessary control information, that is, performs a function of header compression. A Radio Resource Control (RRC) layer located at the lowest part of the third layer is defined only in the control plane. The RRC layer controls logical channels, transmission channels, and physical channels related to the establishment, reconfiguration, and release of radio bearers (RBs). At this time, RB denotes a service provided by the second layer for data transmission between the terminal and the E-UTRAN. If an RRC connection is established between the RRC layer of the terminal and the RRC layer of the wireless grid, the terminal is in the RRC connected mode. Otherwise, the terminal is in an RRC idle mode. A Non-Access Stratum (NAS) located at the top of the RRC layer performs functions such as dialog management, mobility management, and the like. Setting one of the constructed eNB cells to one of 1.25 MHz, 2.5 MHz, 5 MHz, 1 〇 MHz, 20 MHz, and the like, to provide downlink or uplink transmission services to multiple terminals machine. At this time, different cells can be set to provide different bandwidths. The downlink transmission channel for transmitting data from a network to a terminal may include a broadcast channel (BCH) for transmitting system information, and a paging channel for transmitting paging messages (paging) Channel, PC Η), and one is used to transmit other user traffic or control messages under the shared channel (SCH). The traffic or control messages for the downlink point-to-multipoint service 多 'multicast or broadcast service' can be transmitted via a downlink SCH or via a separate downlink multicast channel (MCH). In addition, the uplink transmission channel for transmitting data from a terminal 200910813 to a network may include a random access channel (RACH) for transmitting initial control messages and one for transmitting user information. Uplink shared channel (SCH) for service or control messages »

B) is responsible for controlling or allocating the radio resources of the uplink or the uplink. That is, 'the base station decides which terminal or which or how many radio resources, after which or which to make the decision, the base station transmits the information to the machine so that the terminal can perform the above-mentioned chain according to the information. Road transmission. In the prior art, the terminal is powered in a connected mode. However, in recent years, there have been many shortcomings based on JP (the packet-based service' in the continuous use of wireless in this connection mode, because these IP-based service-based service packets, more precisely, even in the connection mode The period of the packet.

'The terminal will be given in detail— Description of an RRC connection method. The rrc state relates to whether a RRC is logically connected to the RRC E-UTRAN of the E-UTRAN to form a logical connection. If the RRC of the final E-UTRAN forms a logical connection, the RRC connection state is established. Conversely, if there is no logical connection between the RRCs of the terminal E-UTRAN, then the resource and the downlink base station (eNode resources and the downlink machine can use which specific time period. To a corresponding terminal link or downlink) Continuous use of the wireless internet protocol) Electrical resources can cause a continuous number of non-transmission periods that are not always transmitted.

為“ RRC閒置狀態”。當終端機處於RRC連接狀態中且 E-UTRAN可因此根據小區之單元辨認出存在相應終端機 時，E-UTRAN可有效地控制終端機。反之，E-UTRAN不 能辨認出一處於閒置狀態中之終端機。處於閒置狀態中之 終端機可由CN根據位置區域之單元或追蹤（路由）區域 之單元進行管理，該等區域為比小區大之區域。具體而言， 僅根據大區域（諸如，位置區域或追蹤（路由）區域）之 單元來辨認出一處於閒置狀態之終端機的存在，而為了接 收典型的行動通信服務（諸如聲音或資料），該終端機必須 轉變進入連接狀態中。 當使用者一開始接通終端機之電源時，終端機首先偵 測一適當小區，且在該相應小區中維持其閒置狀態。當需 要形成一 RRC連接時，處於閒置狀態中之終端機經由RRC 連接程序與E-UTRAN之RRC形成該RRC連接，且轉變進 入RRC連接狀態中。存在一些需要一處於閒置狀態中之終 端機形成RRC連接之情況。舉例而言，由於使用者之呼叫 嘗試而造成可能需要上行鏈路資料傳輸，或者是為了回應 於自E-UTRAN接收之傳呼訊息而可能需要之回應訊息的 傳輸。 在下文中，將給出關於系統資訊之描述。該系統資訊 可包括一終端機為與一基地台形成連接所需知道之所有資 訊。因此，在終端機嘗試連接至基地台之前，其應接收所 有系統資訊，且始終具有最新系統資訊。此外，鑒於一小 區内之所有終端機應知道系統資訊，基地台會定期傳輸系 11 200910813 統資訊。 可將系統資訊分成一主要資訊區塊（M a s t e r Information Block，MIB)、一排程區塊（Scheduling Block, SB)、一 系統資訊區塊（System Information Block, SIB)、 及其類似物。該MIB用來告知終端機關於一相應小區之實 體構造（例如，頻寬及其類似方面）。該SB用來告知終端 機關於SIB之傳輸資訊（例如，傳輸週期及其類似方面 該SIB涉及彼此相關之系統資訊之集合（或聚集）。舉例 而言，某一 SIB可包括僅鄰近小區之資訊，且另一 SIB可 包括關於一僅由終端機使用之上行鏈路無線電通道之資 訊β 在相關技術中，為了使一終端機接收適當服務，而不 在系統中造成任何麻煩，該終端機應始終具有最新系統資 訊。然而，該系統資訊需要被一新進入一小區中之終端機 接收，或被一在一特定小區中新打開之終端機接收。因此， 基地台會反復傳輸系統資訊。在該種狀況下，需要終端機 始終接收系統資訊之情形可致使如下問題產生··在一已接 收最新系統資訊之終端機上浪費不必要能量。因此，有必 要在只有當實際修改了系統資訊時，才讓終端機讀取系統 資訊。 【發明内容】 本發明之目的在於提供一種用於當系統資訊經修改時 一終端機有效接收及更新該系統資訊之方法，其中一基地 台使用一其管理下之小區之最少無線電資源，該基地台將 12It is "RRC idle state". When the terminal is in the RRC connected state and the E-UTRAN can thus recognize the presence of the corresponding terminal according to the unit of the cell, the E-UTRAN can effectively control the terminal. Conversely, E-UTRAN cannot recognize a terminal that is in an idle state. The terminal in the idle state can be managed by the CN according to the unit of the location area or the unit of the tracking (routing) area, which is an area larger than the cell. Specifically, the presence of a terminal in an idle state is recognized only by a unit of a large area such as a location area or a tracking (routing) area, and in order to receive a typical mobile communication service (such as voice or material), The terminal must be transitioned into the connected state. When the user first turns on the power of the terminal, the terminal first detects an appropriate cell and maintains its idle state in the corresponding cell. When it is required to form an RRC connection, the terminal in the idle state forms the RRC connection with the RRC of the E-UTRAN via the RRC connection procedure, and the transition enters the RRC connected state. There are some cases where a terminal that is in an idle state needs to form an RRC connection. For example, an uplink data transmission may be required due to a user's call attempt, or a response message may be required in response to a paging message received from the E-UTRAN. In the following, a description will be given regarding system information. The system information may include all of the information that a terminal needs to know to form a connection with a base station. Therefore, before the terminal attempts to connect to the base station, it should receive all system information and always have the latest system information. In addition, since all terminals in a small area should know the system information, the base station will periodically transmit the information of the system. The system information can be divided into a main information block (MIB), a Scheduling Block (SB), a System Information Block (SIB), and the like. The MIB is used to inform the terminal about the physical structure (e.g., bandwidth and similar aspects) of a corresponding cell. The SB is used to inform the terminal about the transmission information of the SIB (for example, the transmission period and the like, the SIB relates to a collection (or aggregation) of system information related to each other. For example, a certain SIB may include information only for neighboring cells. And another SIB may include information about an uplink radio channel used only by the terminal. In the related art, in order for a terminal to receive an appropriate service without causing any trouble in the system, the terminal should always It has the latest system information. However, the system information needs to be received by a terminal that is newly entered into a cell, or received by a newly opened terminal in a specific cell. Therefore, the base station repeatedly transmits system information. In such a situation, the situation that the terminal needs to receive the system information at all times may cause the following problems to occur: • unnecessary energy is wasted on the terminal that has received the latest system information. Therefore, it is necessary to only when the system information is actually modified. The terminal device is allowed to read system information. [Invention] The object of the present invention is to provide a method for A valid terminal receives system information updating method and the modified system information, the one base station which uses a minimum radio resources of a cell under the management of the base station 12

If the base station wishes to change the system information of the forward transmission, the time period information related to the reception or modification of the system information relates to a period in which the modified system information can be transmitted. At this time, the system information receiving or modifying the relevant time period information may involve one time unit time in which the base station can modify the system information, or a time period during which the base station can start transmitting the modified system information. Alternatively, it may involve a period of time during which the base station may modify system information. In addition, the time period information related to the system information collection or modification may relate to a period in which the base station changes the system information to perform the next modification of the system information. In terms of system resources modification, it may involve a period in which the terminal starts to check whether the information has been changed. The time period related to system information reception or modification may involve a period of time during which the terminal device considers transmitting the system with the same content after checking that the system information is compared with the previously received system information. News. Alternatively, it may involve an operation in which an operation should be performed to check if a portion of the system information modification will be performed in the next time period. The time period information related to the receipt or modification of the system information may relate to a period in which the terminal periodically checks whether the system information has been modified or receives the system information periodically. That is, in the present invention, the base station sets the system information modification period and transmits the system information with the same content in the same system information modification period. Therefore, the base station can transmit system information only in different system information modification periods. That is, the system information modification period involves a period in which the system information is transmitted in the same manner. In terms of the system information modification period, the base station informs the terminal that the information about the transmission can be connected to the local communication system. The information is as follows: start point, duration period, duration length, and the like. News. Based on this information, the terminal opportunity knows about each of the system information modification weeks. Therefore, in the present invention, the base station is configured to set information about the system information modification period and the notification and the system information modification period. The terminal considers (determines) the system information of the same content in the same system information modification period. Therefore, if it is checked that the system information is not modified in the current system resource modification period, the terminal determines that the system information is not changed in the system information modification period in comparison with the previous system information, thereby not reading the system information. In addition, if the terminal detects that the system message has not been modified in the current system information modification period, the terminal checks whether the system information will be modified in the next system information modification period. If it is determined that the information is modified in the current system information modification period, the terminal will take the system information. At this time, when the system information should be read, the terminal device reads the information in the previous system information modification period. Therefore, in the present invention, the base station sets the system information modification period and notifies the information related to the system information change period. The system is configured to transmit system information of the same content during the same system information modification period. Therefore, if the base station determines that the system information should be modified during a certain system information modification period during the transmission period, the base station transmits the system information that has been transmitted during the current system information modification period, and then transmits the data in the next system information modification period. Modify the system message. Changes to system information can only occur at a particular radio frame (ie, the concept of a modification cycle is used). The system information message can be transmitted many times in the same period of the modification content as defined by its arrangement. The modification is expected to be the first to repair the capital is to read the repair week, then the capital is also the week 19 200910813 The boundary is defined by SFN mod N, where N is configured by system information. When the network changes all or some of the information in the system information, it first notifies the terminal (UE) about the change, and the notification can be completed in a modification cycle. During the next modification cycle, the network can transmit updated system information. After receiving the change notification, the terminal (UE) can know that the current system information is valid before the next modification period limit. After this limit, the terminal can get new system information. The present invention can provide a method for receiving system information for uplink access in a wireless communication system, the method comprising: receiving system information and periodic information related to system information modification; determining whether system information needs to be modified; To determine that the system information needs to be modified, the updated system information is received based on the periodic information. The period information includes at least one of a start point of one of the modification periods, a termination point of the modification period, or a total duration (time period) of the modification period. The periodic information indicates a shortest period in which the system information can be modified; the periodic information indicates that the base station can change one of the shortest periods of the system information; the periodic information indicates that the base station waits for the next updated system information after changing the system information. One of the shortest times; the periodic information indicates in the terminal where the one of the longest periods of system information has been modified; the periodic information indicates the start time of receiving the modified system information. When the period information is received in a certain modification period, the modified system information is also received in the certain modification period; when the period information is received in a certain modification period, the other is different from the certain modification period.
