Referring to FIG. 2, the terminal includes a communication unit 210, a storage unit 220, and a controller 230.

The communication unit 210 performs functions for transmitting and receiving signals through a wireless channel. For example, the communication unit 210 performs conversion between a baseband signal and a bit string in accordance with a physical layer standard of the system. For example, at the time of data transmission, the communication unit 210 generates complex symbols by encoding and modulating a transmission bit stream. Also, upon receiving the data, the communication unit 210 demodulates and decodes the baseband signal to recover the received bit stream. The communication unit 210 may transmit a random access request to the base station 120 and may receive an uplink resource allocation message from the base station 120. The uplink resource assignment message may include a random number and RACH resource identification information transmitted by the UE 110. [ For example, the communication unit 210 may be referred to as a transmission unit, a reception unit, and a transmission / reception unit. The communication unit 210 operates based on the control of the control unit 230. [

According to one embodiment, the communication unit 210 transmits information informing the non-moving mode of the terminal 110 to the base station 120 in the process of updating the location information of the terminal. The communication unit 210 receives the data from the control node 130 via the paging message by transmitting information indicating the non-moving mode of the terminal 110 to the base station 120.

For example, the communication unit 210 transmits information informing the non-moving mode of the terminal 110 through the RRC connection setup complete message. The response may be ACK (acknowledge) or NACK (non-acknowledge).

For example, the communication unit 210 transmits information indicating the non-moving mode of the terminal 110 to the base station 120 and transmits a message requesting broadcasting information. When the non-moving mode of the terminal 110 is registered in the base station 120, the communication unit 210 receives broadcast information from the base station 120.

For example, the communication unit 210 transmits a random access request, receives an uplink resource allocation message, transmits a preamble, receives a random access response including data, and indicates whether data is received And requests re-transmission of the unreceived data by transmitting information.

For example, the communication unit 210 may be referred to as a transmission / reception unit. The transmitting and receiving unit transmits information informing the base station of the non-moving mode of the terminal and receives data before the resource control setting is completed from the base station. The information indicating the non-moving mode includes at least one of information indicating that the terminal is fixedly located at a predetermined position for a predetermined time, information indicating whether the terminal supports the non-moving mode, and available time information.

The transceiver transmits broadcast request information including broadcast identification information and broadcast information to the base station. The transmitting and receiving unit transmits information informing the non-moving mode of the terminal through the resource control setting request message. The transmitting and receiving unit transmits a retransmission request for the unreceived data through the random access message.

In particular, the storage unit 220 may store a codebook for feedback of channel information. According to one embodiment, the storage unit 220 stores a measurement value of an accelerometer for measuring the movement of the terminal 110. The storage unit 220 stores a specific value for comparison with the measured value of the accelerometer. The storage unit 220 stores information indicating the non-moving mode of the terminal 110. [ The storage unit 220 stores the broadcast identifier received from the base station 120 or the control node 130 through the communication unit 210. The storage unit 220 stores information indicating whether the base station 120 or the control node 130 included in the system information received through the communication unit 210 from the base station 120 or the control node 130 supports non-moving mode. The communication unit 210 transmits information informing the non-movement mode through one of the resource control setup messages.

The controller 230 controls overall operations of the terminal. For example, the control unit 230 transmits and receives signals through the communication unit 210. Also, the control unit 230 records and reads data in the storage unit 220. To this end, the control unit 230 may include at least one processor. For example, the control unit 230 may include a communication processor (CP) for performing communication control and an application processor (AP) for controlling an upper layer such as an application program. According to one embodiment, the controller 230 determines the movement mode of the terminal 110 by comparing the measured value of the accelerometer with a threshold value. If the measured value of the accelerometer is less than or equal to the threshold value, the controller 230 determines that the terminal 110 is in the non-moving mode. If the measured value of the accelerometer is greater than the threshold value, the terminal 110 is determined to be in the moving mode. The control unit 230 controls operations of the communication unit 210 and the storage unit 220. The control unit 230 controls transmission / reception of broadcast information of the communication unit 210 based on the broadcast identifier stored in the storage unit 220. The controller 230 may include at least one processor. For example, when the control unit 230 determines that the terminal is fixedly located in a specific area or a specific location by using a device capable of detecting a change in position of an accelerometer, GPS (Global Positioning System), etc., Mode.

[ The updated location information is stored in the storage unit of the base station 120.

In step 509, the terminal 110 transmits a response to the data. The terminal 110 transmits a response to the data through the RRC connection establishment completion message. According to steps 505, 507, and 509, the terminal 110 can receive data before the RRC connection by transmitting information indicating the non-moving mode of the terminal 110. [ For example, the information indicating the non-moving mode of the terminal 110 and the available time information can be transmitted through the RRC connection establishment completion message. When the terminal 110 is in the non-mobile mode, it may be referred to as a non-mobile terminal or a MTC (Machine Type Communication) terminal. Here, steps 505, 507, and 509 may be referred to as a resource control connection setting 511 procedure. An RRC connection setup completion message including information informing the non-movement mode of the terminal 110 and available time information can be set as shown in Table 1 below.

According to Table 1, the RRC connection request completion message includes MTC mode and MTC mode available time setting information. The MTC mode includes a non-stationary mode, a stationary mode, and a spare. The MTC available time is set from 0 to 7200 as an integer.

FIG. 6 illustrates a data transmission / reception procedure in a wireless communication system according to an embodiment. FIG. 6 illustrates a procedure for a UE 110 to receive data from a control node 130 through a paging message without an RRC establishment procedure, when the UE 110 is in a non-mobile mode for a predetermined period of time.

Referring to FIG. 6, in step 601, the terminal 110 updates the location information of the terminal. The terminal 110 periodically reports information on its location to the control node 130 through the base station 120. [ The base station 120 transmits the location information of the terminal received from the terminal 110 to the control node 130. Here, the terminal 110 transmits information informing the non-moving mode of the terminal 110 to the base station 120. The base station 120 transmits information indicating the non-moving mode of the terminal 110 received from the terminal 110 to the control node 130. The information indicating the non-moving mode is information informing that the terminal 110 is continuously positioned without moving from a specific position when the terminal 110 determines that the position of the terminal 110 is fixed to a specific position unchanged for a predetermined time. The terminal 110 can determine that the position of the terminal 110 is fixed to a specific position using an accelerometer.

In step 603, the terminal 110 stops at the same position. That is, the terminal 110 that has transmitted information informing the non-moving mode of the terminal 110 to the control node 130 through the base station 120 stops at the same position. For example, the terminal 110 stops at the same position in the cell of the base station 120 that was located most recently in time. For example, the terminal 110 can determine that the terminal 110 is fixedly located in a specific area or a specific location by using a device capable of detecting a change in terminal location such as an accelerometer, GPS, and the like.

In step 605, the control node 130 transmits data to the base station 120 through the paging message. For example, the data may be small-sized data contained within the paging message. Further, the data may be referred to as downlink data. The control node 130 may determine that the terminal 110 is fixed at the same position based on the information indicating the non-moving mode of the terminal 110 received in step 601. [ For example, since the location of the terminal 110 is fixed to the same position, the control node 130 transmits the paging message to the terminal 110 without receiving the updated location information of the terminal 110 or performing the RRC connection establishment procedure of the terminal 110 Can be transmitted.

In step 607, the BS 120 transmits data to the UE 110 through a paging message. The base station 120 may determine that the terminal 110 is fixed at the same position based on the information indicating the non-moving mode of the terminal 110 received in step 601. [ For example, since the location of the terminal 110 is fixed to the same position, the base station 120 transmits data in the paging message transmission procedure to the terminal 110 without performing the procedure of receiving the updated location information of the terminal or the RRC connection establishment procedure of the terminal 110 Can be transmitted. In step 607, the BS 120 may transmit data to the UE 110 faster than the conventional method of transmitting data through the RRC message.

In step 609, the terminal 110 transmits a response to the data to the base station 120. The UE 110 transmits a response to the received data through the RRC connection setup request message transmission procedure in the RRC connection setup procedure. The terminal 110 recognizes that the position of the terminal 110 is fixed. The base station 120 and the control node 130 recognize that the position of the terminal 110 is fixed. Therefore, the base station 120 transmits data through the paging message before establishing the resource control connection. Data is received earlier than when data is received in the resource control connection setting procedure described in FIG. Accordingly, the procedure for the base station 120 to transmit data to the terminal 110 moves to the resource control connection establishment 602.

FIG. 7 illustrates a procedure in which a terminal transmits and receives data in a wireless communication system according to an embodiment. 7 illustrates a procedure for informing the base station 120 or the control node 130 that the terminal 110 is fixed to a specific position by transmitting information indicating a non-movement mode of the terminal 110 and receiving data before establishing a resource control connection at a fixed position .

Referring to FIG. 7, in step 701, the terminal 110 transmits information indicating the non-moving mode of the terminal 110 to the base station 120. FIG. When the measurement value of the accelerometer is smaller than the threshold value, the terminal 110 determines that the position of the terminal 110 is fixed at a predetermined position and transmits the information to the base station 120 . The base station 120 stores information indicating the non-moving mode of the terminal 110 received from the terminal 110 in the storage unit. In other words, the base station 120 determines that the position of the terminal 110 is fixed at a specific position. Accordingly, the base station 120 can transmit the data received from the control node 130 through the paging message to the terminal 110.

In step 703, the terminal 110 receives data through the paging message with the base station 120. The terminal 110, the base station 120, and the control node 130 know that the terminal 110 is fixed at a specific position based on information indicating the non-moving mode of the terminal 110. Generally, the terminal 110 must perform an RRC connection establishment procedure in order to transmit and receive data. However, the base station 120 and the control node 130 determine that the terminal 110 is fixed at a specific position based on the information indicating the non-moving mode. The base station 120 transmits data through the paging message to the determined position where the terminal 110 is fixed. The terminal 110 at a fixed location receives data through a paging message received from the base station 120. The paging message is a message used by the base station 120 to call the terminal 110. The paging message may be transmitted with a small amount of data.

FIG. 8 illustrates a procedure for a base station to transmit and receive data in a wireless communication system according to an embodiment. FIG. 8 illustrates a procedure for transmitting data through a paging message to the UE 110 before establishing a resource control connection when the Node B 120 receives information indicating the non-moving mode of the UE 110 from the UE 110.

Referring to FIG. 8, in step 801, the BS 120 receives information indicating the non-moving mode of the UE 110 from the UE 110. FIG. When the measurement value of the accelerometer is smaller than the threshold value, the terminal 110 determines that the position of the terminal 110 is fixed at a predetermined position and transmits the information to the base station 120 . The base station 120 stores in the storage unit information indicating the non-moving mode of the terminal 110 from the terminal 110. [ The base station 120 determines that the position of the terminal 110 is fixed based on the information indicating the non-moving mode of the terminal 110. [ Accordingly, the base station 120 can transmit information or data to a fixed location of the terminal 110. [

In step 803, the base station 120 transmits information indicating the non-moving mode of the terminal 110 received from the terminal 110 to the control node 130. The control node 130 estimates the position of the terminal 110 based on information indicating the non-moving mode of the terminal 110 and determines that the position of the terminal 110 is fixed. The control node 130 transmits data to the base station 120 through a paging message.

In step 805, the base station 120 receives data from the control node 130 through a paging message. For example, the paging message may include data. The base station 120 knows that the terminal 110 is located at a fixed position based on information indicating the non-moving mode of the terminal 110 stored in the storage unit.

In step 809, the base station 120 transmits data to the terminal 110 through the paging message. The base station 120 transmits data to the terminal 110 and the terminal 110 before the RRC connection through the paging message. The paging message is a message for calling the terminal 110. The terminal 110 is fixed at a specific location, and the base station 120 determines that the terminal 110 is fixed at a specific position based on information indicating the non-moving mode of the terminal 110 stored in the storage unit, thereby transmitting data to the terminal 110 through the paging message do.

FIG. 9 illustrates a procedure in which a control node transmits and receives data in a wireless communication system according to an embodiment. 9 illustrates a procedure in which the control node 130 receives information indicating the non-moving mode of the terminal 110 from the terminal 110 via the base station 120 and updates the location information of the terminal 110 to transmit data to the terminal through the paging message . The control node 130 recognizes that the terminal 110 is in the non-moving mode.

Referring to FIG. 9, in step 901, the control node 130 receives information indicating the non-moving mode of the terminal 110 from the base station 120. When the measurement value of the accelerometer is smaller than the threshold value, the terminal 110 determines that the position of the terminal 110 is fixed at a predetermined position and transmits the information to the base station 120 . The control node 130 determines that the position of the terminal 110 is fixed to a specific position based on the information indicating the non-moving mode of the terminal 110. [ The control node 130 is a mobile management entity (MME). The control node 130 manages the mobility of the terminal 110.

In step 903, the control node 130 changes paging and location information of the mobile station based on information indicating the non-mobile mode. The control node 130 transmits data through the paging message by determining that the terminal 110 is in the non-moving mode. The control node 130 changes the position information of the terminal to be fixed to a specific position based on the information indicating the non-moving mode.

In step 905, the control node 130 transmits data to the base station 120 through paging. When the terminal 110, the base station 120, and the control node 130 recognize that the terminal 110 is in the non-mobile mode, the base station 120 transmits the data received through the paging message from the control node 130 to the terminal 110.

10 is a flowchart illustrating a group communication procedure using broadcast identification information in a wireless communication system according to an exemplary embodiment of the present invention. FIG. 10 illustrates a procedure for providing one-to-many group communication among terminals by assigning broadcast identification information to terminals operating in a non-moving mode.

Referring to FIG. 10, in step 1001, the UEs 110-N transmit information indicating a non-moving mode of the UE to the BS 120. FIG. The base station 120 transmits information informing the non-moving mode of the terminal to the control node 130. Information informing the non-moving mode of the terminal that the base station 120 transmits to the control node 130 may be transmitted in the form of a message. The message includes that the control node 130 includes the UEs 110-N in which the base station 120 operates in the non-mobile mode in the cell, and the base station 120 can support the broadcast service to the UEs while the control node 130 can transmit the broadcast data. Lt; RTI ID = 0.0 > a < / RTI > The composition of the message is shown in Tables 2 and 3 below.

According to Table 2, the message includes the type of message and includes MTC-specific service instructions. The message includes the type and criterion of the information object, and includes information for determining importance.

According to Table 3, the MTC-specific service identifier indicates whether the MTC-specific service is supported. When the MTC local service identifier is set to 0, it is either unsupported or non-operational. If set to 1, start the service.

In step 1003, the control node 130 transmits broadcast identification information for group communication to the base station 120. The broadcast identification information is used by the base station 120 to transmit broadcast information to the non-mobile mode terminals 110-N. The broadcast identification information is included in the message transmitted from the control node 130 to the base station 120 as shown in Table 4 below.

According to Table 4, the message transmitted from the control node 130 to the base station 120 includes a message type, broadcast identification information, and MTC target broadcast data. The broadcast identification information is assigned to one of the values from 2 to 100 set in the RRC connection establishment completion or MTC broadcast permission. The broadcast identification information is assigned to the terminal and is used to transmit the broadcast information to the terminal in response to the specified broadcast identification information. The broadcast identification information may be referred to as a broadcast ID. The terminal 110 can selectively receive broadcast information by selecting one of the numbers set in the MTC broadcast permission.

In step 1005, one of the terminals 110-N transmits broadcast request information to the base station 120. The base station 120 receives broadcast request information. The broadcast request information includes broadcast identification information and broadcast information. For example, broadcast information is data that one terminal of the terminals 110-N transmits to the base station 120, and the base station 120 receives broadcast information and provides it to terminals corresponding to the same identification information.

In step 1007, the BS 120 transmits the broadcast information to the UEs 110-N. The base station 120 transmits the broadcast information to the terminals 110-N corresponding to the broadcast identification information according to the broadcast identification information stored in the storage unit. The base station 120 can transmit the broadcast information received from the control node 130 to the terminals 110-N without linking with the upper node. Broadcast information transmitted from the base station 120 to the terminals 110-N is defined as shown in Table 5 below.

According to Table 5, broadcast information can be named as downlink small data. And size information that can be broadcasted at the maximum of broadcast information.

In step 1009, the terminal 110-N transmits a response to the broadcast information to the base station 120. For example, the response to the broadcast information may be an ACK message or a NACK message. The base station 120 transmits a response to the broadcast information to the control node 130. The response sent from the base station 120 to the control node 130 may be conveyed as a message. The messages have the configurations shown in Tables 6 and 7 below.

According to Table 6, the response transmitted from the terminal 110-N includes the result of the MTC service request. Here, the MTC service request is the same as the broadcast request information requested in step 1105 by the terminal 110-N. The results of the MTC service request are separated into 9.2.1.ss information element (IE) types and criteria. 9.2.1.ss can be described in Table 7 below.

According to Table 7, the result of the MTC service request has a range from 0 to 255, and when it is represented as 0, it indicates that broadcast information is received successfully. If it is 1, it indicates failure. When the number is represented by a number from 2 to 255, it indicates a broadcast information reception reservation.

The base station 120 transmits data received from the control node 130 through the paging message to the terminal 110. The data received by the terminal 110 through the paging message can be described with reference to Table 8 below.

According to Table 8, a message representing data includes broadcast identification information and data. The message includes broadcast identification information and data. Broadcast identification information may be specified in the range of 101 to 65535. Data is specified as the maximum data in paging from 1. The message is set by the control node 130. For example, the terminals 110-N that have received the broadcast identification information can perform group communication between terminals that have received the same broadcast identification information. One of the terminals receiving the same broadcast identification information receives data from the base station 120 through a paging message. One of the terminals receiving the same broadcast identification information transmits data received through the paging message to neighboring terminals. For example, the neighboring terminals may be terminals belonging to the same group by receiving the same broadcast identification information as the terminal transmitting the data. For example, the neighboring terminals can recognize the terminal receiving the same broadcast information on behalf of the base station 120 as a hot spot or a base station on an Ad-hoc network. Here, the same broadcast information may be a paging message.

For example, the structure of the broadcast request message may have a structure as shown in Table 9 below.

According to Table 9, the broadcast request information includes broadcasting ID, which is broadcast identification information, and broadcasting small data, which is broadcast data. The broadcast identification information is set from 1 to 100 as an integer. The maximum size of broadcast data is limited.

For example, the paging message may include the structure shown in Table 10 below.

According to Table 10, the paging message includes a broadcasting flag and a data flag. The broadcast flag is set to false when the upper network or the server transmits data for a basic terminal, and the broadcast identification information is set to 101. [ Herein, when the terminal 110 receives the paging message, the terminal 110 recognizes that the data is transmitted from the upper server or the control node 130. The terminal 110 processes the data according to the information included in the paging message.

For example, when the terminal requests a broadcast or a local broadcast is requested from another server in the base station, the base station 120 receives the request, sets the broadcast flag to true for the terminal located in the base station cell, . Here, the terminals process the data according to the broadcasting service procedure defined in the broadcast identification information.

FIG. 11 illustrates a procedure for transmitting broadcast request information by a terminal in a wireless communication system according to an embodiment. 11 illustrates a procedure in which the terminal 110 broadcasts broadcast information through the base station 120. FIG.

Referring to FIG. 11, in step 1101, the terminal 110 determines whether to transmit information informing the non-moving mode of the terminal 110. FIG. When it is determined that the terminal 110 transmits information indicating the non-moving mode of the terminal 110, the terminal 110 recognizes that the terminal 110 is in the non-moving mode. When the terminal 110 is in the non-moving mode, the terminal 110 is located at the same position without moving for a predetermined time. For example, the terminal 110 may be an MTC terminal. The terminal 110 receives the broadcast identification information. The broadcast identification information is set by the control node 130. According to another embodiment, when determining that the terminal 110 does not transmit the information indicating the non-moving mode, the terminal 110 recognizes that the terminal 110 is in the moving mode. As the terminal 110 recognizes the moving mode, the terminal 110 updates the location of the terminal to the control node 130 through the base station 120.

In step 1103, the terminal 110 transmits broadcast request information to the base station 120. The broadcast request information includes broadcast identification information and broadcast information. The broadcast information is data transmitted by the terminal 110 via the uplink. The broadcast information is transmitted from the terminal 110 to the base station 120 to transmit the broadcast request information, the base station 120 to receive the broadcast request information, and to transmit the information indicating the non-mobile mode. In other words, the broadcast information is information broadcasted by the base station 120. The base station 120 stores the locations of the terminals informing the non-moving mode in the storage unit. The terminal 110 can broadcast the broadcast information through the base station 120.

FIG. 12 illustrates a broadcast information transmission procedure of a base station in a wireless communication system according to an embodiment. FIG. 12 illustrates a procedure for transmitting broadcast information to terminals that have transmitted information indicating a non-moving mode without being associated with an upper node, when the base station 120 receives broadcast request information from the terminal 110. FIG.

Referring to FIG. 12, in step 1201, the BS 120 determines whether information informing the non-moving mode of the UE 110 is received from the UE 110. When the base station 120 receives the information indicating the non-moving mode of the terminal 110, the base station 120 determines that the terminal 110 is in the non-moving mode. The terminal 110 stores information indicating the non-moving mode of the terminal 110 in the storage unit. The base station 120 can transmit broadcast information in cooperation with an upper node in a non-mobile mode terminal. In the non-moving mode terminal, the BS 120 can transmit broadcast information, rather than transmitting the broadcast information to the UE. The base station 120 may transmit broadcast information to terminals reporting a non-moving mode. The base station 120 stores the locations of the terminals informing the non-moving mode in the storage unit. The base station 120 can recognize the positions of the terminals notifying the non-moving mode without linking with the upper node.

In step 1203, the base station 120 receives broadcast request information from the terminal 110. The base station 120 recognizes broadcast identification information and broadcast information included in the broadcast request information received from the terminal 110. The base station 120 transmits the broadcast information to the other terminals corresponding to the broadcast identification information. The broadcast request information includes broadcast identification information and broadcast information. For example, the broadcast identification information may be referred to as a broadcast ID.

In step 1205, the base station 120 transmits broadcast information. The base station 120 broadcasts broadcast information included in the broadcast request information received from the terminal 110 to terminals corresponding to broadcast identification information. For example, the terminals corresponding to the broadcast identification information may be terminals located in the cell of the base station 120. The state of the terminals corresponding to the broadcast identification information is a state in which the information indicating the non-movement mode is transmitted to the base station 120 and the control node 130 to update the position information. When base station 120 receives broadcast request information from terminal 110 and transmits broadcast information to other terminals, broadcast information transmission may be referred to as one-to-many group communication.

13 illustrates an operation procedure of a control node in a wireless communication system according to an embodiment. 13 illustrates a procedure in which the control node 130 generates broadcast identification information and transmits the broadcast identification information to the base station 120. FIG.

Referring to FIG. 13, in step 1301, the control node 130 generates broadcast identification information. The broadcast identification information is used when the terminal 110 transmits the broadcast request information to the base station 120 and the base station 120 transmits the broadcast information included in the broadcast request information to the other terminals based on the broadcast identification information. For example, the broadcast identification information may be set to an integer from 1 to 101. The broadcast identification information includes a broadcast flag. If the broadcast flag is set to false, the broadcast request information is transmitted to the upper node. When the broadcast flag is set to TRUE, the base station 120 can transmit broadcast information to other terminals without linking with an upper node.

In step 1303, the control node 130 transmits the broadcast identification information to the base station 120. The base station 120 receives the broadcast identification information and transmits the broadcast identification information to the terminals through the paging message. When the mobile stations are in the non-mobile mode, they can transmit broadcast request information to neighboring terminals by transmitting broadcast request information including broadcast identification information and broadcast information to the base station 120. The base station 120 can transmit the broadcast information to the terminals without linking with the superordinate node.

FIG. 14 illustrates a procedure for informing a mode of a terminal in a wireless communication system according to an embodiment. FIG. 14 illustrates a procedure for determining whether the terminal 110 can operate in the non-moving mode.

Referring to FIG. 14, in step 1401, the terminal 110 updates the location based on the movement detection. The terminal 110 is a non-moving mode terminal having a fixed position. The terminal 110 detects movement using an accelerometer. And updates the position information based on the sensed movement. The terminal 110 transmits the updated location information to the base station 120. The base station 120 transmits the updated location information to the control node 130. The base station 120 stores the updated location information of the terminal 110. The control node 130 changes the location information of the terminal 110 according to the updated location information of the terminal 110.

In step 1403, the terminal 110 determines whether the location is updated. The terminal 110 determines whether the location information of the terminal 110 should be updated using the accelerometer. If the value measured by the accelerometer is smaller than the threshold value, the terminal 110 does not update the position information. If the value measured by the accelerometer is larger than the threshold value, the terminal 110 updates the position information. If the value measured by the accelerometer is greater than the threshold value, the terminal 110 determines that movement is frequently performed. That is, when the terminal 110 frequently moves, the terminal 110 determines that it is not operating in the non-moving mode.

In step 1405, when the terminal 110 frequently updates the location, the terminal 110 transmits information indicating the mobile mode to the base station 120. The base station 120 transmits to the control node 130 information indicating that it is in the movement mode received from the terminal 110. The base station 120 and the control node 130 recognize that the terminal 110 is not in the non-moving mode. When the terminal 110 frequently changes its location in the serving cell of the base station, the terminal 110 transmits information indicating that the terminal 110 does not operate in the non-moving mode to the base station 120. The terminal 110 determines that it is not suitable for the non-moving mode when the location is frequently updated. It transmits information to the base station 120 and the control node 130 informing that the terminal 110 is not suitable for the non-moving mode, thereby saving the power of transmitting the paging message.

FIG. 15 illustrates an information transmission procedure according to a mode of a terminal in a wireless communication system according to an embodiment. 15 illustrates a procedure in which the terminal 110 determines movement of the terminal 110 according to the measurement value of the accelerometer and transmits information differently according to the determination result.

In step 1501, the terminal 110 measures the moving speed of the terminal using the accelerometer, and compares the measured value and the threshold value. When the measured value of the accelerometer is smaller than the threshold value, the terminal 110 determines that the terminal 110 is not frequently moved. For example, if the terminal 110 does not frequently move, the terminal 110 determines that the location of the terminal 110 is fixed. When the measured value of the accelerometer is greater than the threshold value, the terminal 110 determines that the terminal 110 moves frequently. For example, if the terminal 110 frequently moves, the terminal 110 determines that the location of the terminal 110 is not fixed.

In step 1503, the terminal 110 determines that the position of the terminal 110 is fixed. In accordance with the determination result, the terminal 110 transmits information indicating the non-moving mode to the base station 120. The UE 110 receives the data through the paging message transmitted from the control node 130 without transmitting the RRC connection establishment procedure by transmitting the information indicating the non-movement mode to the BS 120.

In step 1505, the terminal 110 determines that the location of the terminal 110 is frequently moved. In accordance with the determination result, the terminal 110 transmits information indicating the movement mode to the base station 120. The terminal 110 saves power consumed in the paging message by transmitting information indicating that the mobile terminal is in the moving mode.

FIG. 16 illustrates a bitmap of support information in a wireless communication system according to an embodiment. 16 illustrates a support information bitmap in which non-moving mode support information of a terminal is added to system information.

Referring to FIG. 16, system information is included in one area to eight areas. 1 area includes information on a timer, and 4 area 1602 does not include information as spare. Areas 5 to 8 include support information of the terminal network. The terminal 110 transmits system information to the base station 120.

The non-moving mode support information of the terminal 110 may be included in the four areas 1602 marked as reserved. The non-moving mode support information of the terminal 110 indicates whether the terminal 110 supports the non-moving mode. For example, when the non-moving mode supporting information is input as '1', the terminal 110 supports the non-moving mode. On the other hand, when the information indicating whether or not to support the non-moving mode is input as 0, the terminal 110 does not support the non-moving mode. The non-moving mode of the terminal 110 indicates that the terminal 110 is fixedly located at a specific position. A terminal fixed at a specific location may be referred to as an MTC terminal.

17 illustrates an information bitmap in a wireless communication system according to an embodiment. Figure 17 illustrates a bitmap of non-moving mode information configuration including non-moving mode support information and available time.

Referring to FIG. 17, the information bitmap includes a first area 1702 and a second area 1704. The first area 1702 includes non-moving mode information of the terminal. The second area 1704 includes available time information and non-moving mode support information. The information bitmap is information transmitted from the terminal 110 to the control node 130 through the base station 120.

The first area 1702 includes information of the non-moving mode of the terminal from 1 to 8.

The second area 1704 includes non-moving mode support information of the terminals 1 to 2. For example, the non-mobile mode support information of the terminal can be set using numbers. When set to 0, the terminal does not support non-moving mode. When set to 1, the terminal supports non-mobile mode. The second area 1704 includes available time information from 3 to 8. The available time information can be set in units of time.

18 shows a data retransmission request procedure in a wireless communication system according to an embodiment. FIG. 18 illustrates a procedure for a terminal 110 to request retransmission of unreceived data through random access.

Referring to FIG. 18, in step 1801, the terminal 110 transmits a preamble to the base station 120. The terminal 110 selects a RACH resource based on the system information transmitted from the base station 120, and transmits a preamble through a selected random access channel (RACH) resource. For example, the random access can be classified into a contention scheme and a non-contention scheme. In the case of the non-contention-based random access, the base station 120 allocates a specific random access resource to the specific UE so as to perform random access without competition and succeed in access. Assignment of a specific random access resource to a specific terminal is possible when the base station 120 knows the existence of the terminal 110. [ Therefore, the non-contention type random access is applied only in a limited situation such as when the terminal 110 performs handover. In the case of a competitive access method, the base station 120 does not designate a specific terminal but attempts to random access the random access resources allocated by the terminals through competition.

In step 1803, the UE 110 receives a random access response from the BS 120 in a physical downlink service channel (PDSCH). Here, the UE 110 is allocated an uplink resource, a preamble identifier, and a temporary C-RNTI (cell-radio network temporary identifier) from the base station 120. The base station 120 may allocate a C-RNTI to the UE through an uplink resource allocation message by transmitting an uplink resource allocation message.

In step 1805, the terminal 110 transmits a random access message. The UE 110 transmits a random access message through an uplink resource allocated from the BS 120. The random access message is transmitted along the S-TMSI (S Temporary Mobile Subscriber Identity) and the BSR. The terminal 110 transmits information indicating whether the terminal 110 has received data in a random access message. For example, the terminal 110 can receive unreceived data from the base station 120 when the terminal 110 transmits information including information indicating that data is not received in the random access. For example, information indicating whether the terminal 110 included in the random access message has received data is transmitted according to the CL-FLAG.

In step 1807, the UE 110 receives a contention solution message on the PDSCH using the C-RNTI. Here, the terminal 110 receives unreceived data from the base station 120 through a default data radio bearer (DRB). The DRB is jointly established between the terminal 110 and the base station 120. The base station 120 allocates uplink resources for data. Then, the terminal 110 and the base station 120 perform the same random access procedure.
