BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to wireless communications and, more particularly, to methods and apparatus for transmitting paging messages in a wireless communication system. [Prior Art] The Institute of Electrical and Electronics Engineers (IEEE) 8〇216e standard was adopted by the International Telecommunications Union Radiocommunication Department (ITU-R) under the name "WMAN-OFDMA TDD" in 2007. As the sixth standard of International Mobile Telecommunications (IMT)-2000, the ITU-R is one of the departments of the International Telecommunication Union (ITU). The advanced system of β ΙΜΤ has been developed by ITU_R as the next generation after IMT-2000 ( That is, the fourth generation) mobile communication standards. The IEEE 8〇2.16 Working Group (WG) decided to implement the 8〇16m plan to establish the existing IEEE 802.1 6e revision standard as a standard for IMT advanced systems. As can be seen from the above, the 8〇216m standard has two complaints, that is, continuity with the past (ie, the existing 8〇2 16e standard revision 201246858) and the future (ie, Continuity of the standard for the next generation of IMT advanced systems. Therefore, the '8〇2.丨6ηι standard needs to meet all the requirements of the IMT Advanced System while maintaining compatibility with the 802.1 6e-compliant mobile WiMAX system. The Institute of Electrical and Electronics Engineers (IEEE) 8〇2.16p standard is being developed for the optimization of machine-to-machine (M2M) communication based on the IEEE 802.16e standard and the IEEE 802.16m standard. M2M communication can be defined as the exchange of information performed in the core network, between the subscriber station and the server, or between the subscriber stations without any human interaction. In the IEEe 802.16p standard, the enhancement of media access control (MAC) for the IEEE 8〇216 standard and the minimum variation of the orthogonal frequency division multiple access (OFDM) physical layer (PHY) in the licensed band are being continuously discussed. . Due to the discussion of the IEEE 802.16p standard, wide-area wireless coverage is required in licensed bands and the scope of application automation M2M communication can be increased for observation and control purposes. The requirements required for many M2M applications when accessing the network are significantly different from those required for human-initiated or human-controlled network access. M2M applications can include vehicle telematics services, health monitoring of biosensors, remote maintenance and remote control, smart metering, and automated services for consumer devices. M2M application requirements may include very low power consumption, a larger number of devices, short burst transmissions, device tampering detection and reporting, and improved device authentication. The paging message is a Media Access Control (MAC) message, and the media access 201246858 control message is received by the Machine to Machine (M2M) device operating in idle mode from the Base Station (BS) in each paging cycle. At the same time, most M2M applications have traffic characteristics in which relatively small messages are transmitted via the uplink (UL) at a fixed location. In addition, the ul message is mainly used for non-instant periodic reports. Therefore, there is a need for a method for effectively performing non-instant periodic reporting of Bs by a Sa2 M2M device. SUMMARY OF THE INVENTION The present invention provides a method and apparatus for transmitting paging messages in a wireless communication system. The present invention also provides a method of using a paging message to trigger uplink data transfer from a machine to machine (M2M) device. In one aspect, a method of transmitting uplink (UL) data by a machine-to-machine (M2M) device in a wireless communication system is provided. The method includes the steps of: receiving a paging message from a base station, the paging message including an indicator for causing the M2M device to transmit the UL data; and, upon receiving the paging message, based on an indicator for causing the M2M device to transmit the UL data The UL data is transmitted to the base station. The indicator used to cause the M2M device to transmit UL data can be one bit. If the value of the indicator used to enable the M21V [device to transmit UL data] is i, the UL data transmission of the M2M device may be indicated. The paging message can be broadcast. The M2M device can be fixed. 201246858 UL data can be non-immediate ul data. In another aspect, a method for transmitting uplink (UL) data by machine to machine (M2M) I is provided in a wireless communication system. The method includes the following steps: receiving a release login response message from the base station. The release login response message includes the transmission type and the maximum number of paging cycles during the idle mode: during the corresponding number of times (the maximum number of paging pain rings X) Waiting for receiving a beer message for causing the M2M device to transmit the UL data during the period of the length of the paging cycle; and transmitting the UL data to the base station. The transfer type can be one bit. The value of the transfer type can be 1.

If the value of the transmission type is 丨, the transmission type may indicate that the UL data transmission is allowed only after the M2M device receives the paging message for causing the M2M device to transmit the UL data. - When a paging message is received during a period corresponding to (the maximum number of paging cycles, paging cycle), the UL data can be transmitted immediately after receiving the paging message. If the paging message is not received during the period corresponding to (the maximum number of paging cycles\pages), then the period corresponding to (the maximum number of paging loops, the paging loop) expires, and the UL data can be transmitted. The message may include an indicator for causing the M2M device to transmit ul data, and the indicator has a value of one. The paging message can be broadcast. In another aspect, a machine pair 201246858 machine (M2M) device is provided in a wireless communication system. The M2M device includes a radio frequency (RF) unit for transmitting or receiving a radio signal and a processor coupled to the RF unit, wherein the processor is configured to: receive a paging message from the base station, the paging message including An indicator for causing the M2M device to transmit UL data; and upon receiving the paging message, transmitting the UL data to the base station based on an indicator for causing the M2M device to transmit the UL data.

In a variety of wireless communication systems for frequency multiple access (SC-FDMA). CDMA can be implemented with radio technologies such as Universal Terrestrial Radio Access (UTRA) or CDMA2000. TDMA can be implemented using radio technologies such as Global System for Mobile Communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data Rate GSM Evolution (EDGE). OFDM A can be implemented with a radio technology such as IEEE 802.1 1 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802-20 or Evolved UTRA (E-UTRA).

LTE-A (Advanced) is an evolution of 3GPP LTE. The IEEE 802.16m is mainly described as an example in order to clarify the specification, but the technical spirit of the present invention is not limited to ΙΕ]ΞΕ 8 02.16m. Figure 1 shows a wireless communication system. Referring to Figure 1, the wireless communication system 1 includes one or more base stations (B § ) 11. BS 11 provides communication services to individual geographic regions (generally referred to as "communities") i5a, 15b, and 15c. Each of the cells is divided into a number of areas (referred to as "sectors"). User equipment (UE) 12 may be fixed or mobile, and UE 12 may be referred to as another term, such as action a (MS), mobile terminal (MT), user terminal (UT), subscriber station. (ss), wireless device, personal digital assistant (PDA), wireless data modem or handheld device. In general, B S 11 refers to a fixed station that communicates with UE 12, and BS 11 may be referred to as another term, such as an evolved NodeB (eNB), a base transceiver system (BTS), or an access point. The UE generally belongs to one cell. The cell to which the UE belongs is referred to as a serving cell. The B s that provides communication services to the serving cell is called servo b s. The wireless communication system is a cellular system' and thus the wireless communication system includes other cells adjacent to the serving cell. Other cells adjacent to the serving cell are referred to as neighboring cells. A BS that provides communication services to neighboring cells is referred to as a neighbor BS. The servo cell and the neighboring cell are relatively determined on the basis of ue. This technique can be used in the downlink (DL) or uplink (UL). 9 201246858 In general, DL refers to communication from BS 11 to UE 12, and UL refers to communication from UE 12 to BS 11.

Figure 2 shows the basic M2M service system architecture for IEEE 802.16 that supports machine-to-machine (M2M) communication. The basic M2M service system architecture 20 includes a mobile network operator (MNO) 21, an M2M service consumer 24, at least one IEEE 802.16 M2M device (hereinafter referred to as an 802.16 M2M device) 28, and at least one non-IEEE 802.16 M2M device 29. The MNO 21 includes an Access Service Network (ASN) and a Connectivity Service Network (CSN). The 802.16 M2M device 28 is an IEEE 8 02.16 mobile station (MS) with M2M functionality. The M2M server 23 is integral for communication with one or more 802.16 M2M devices 28. The M2M server 23 has an interface that can be accessed by the M2M service consumer 24. The M2M service consumer 24 is a user of the M2M service. The M2M server 23 can be internal or external to the CSN, and the M2M server 23 can provide a particular M2M service to one or more 802.16 M2M devices 28. The ASN may include an IEEE 802.16 base station (BS) 22. The M2M application operates based on the 802.1 6 M2M device 28 and the M2M server 23. The basic M2M service system architecture 20 supports two types of M2M communication, that is, M2M communication between one or more 802.16 M2M devices and an M2M server, or point-to-multipoint communication between an 802.16 M2M device and an IEEE 802.16 BS. . Figure 2 Basic M2M Service System Architecture Allows 802.16 M2M devices to act as non-IEEE 802.16 M2M devices 10 201246858

Gather points to operate. Non-IEEE 802.16 M2M devices use a radio interface other than IEEE 802.16, such as IEEE 802.11, IEEE 802.15, PLC, or the like. In this case, the non-IEEe 802.16 M2M device is not allowed to change the radio interface to IEEE 802.16. Figure 3 shows an advanced M2M service system architecture supporting IEEE 8〇2.10 for machine-to-machine (M2M) communication.

In the advanced M2M service system architecture, 802.16 M2M devices can operate as aggregation points for non-IEEE 802.16 M2M devices, and 802.16 M2M devices can also operate as aggregation points for 802.16 M2M devices. In this case, in order to perform the aggregation function of the 802.16 M2M device and the non-802.16 M2M device, the radio interface can be changed to IEEE 802.16. In addition, the advanced M2M service system architecture supports peer-to-peer (P2P) connectivity between 802.16 M2M devices. In this case, the P2P connection can be established on IEEE 802.16 or another radio interface such as IEEE 802.1 1, IEEE 8 02.15, PLC or the like. Hereinafter, the IEEE 802.16e and IEEE 802.16m frame structures will be described. Figure 4 shows an example of an IEEE 802.16e frame structure. The Time Division Duplex (TDD) frame structure of IEEE 802.16e is shown in FIG. The TDD frame includes a downlink (DL) transmission period and an uplink (UL) transmission period. The DL transfer cycle is temporarily preceded by the UL transfer cycle. The DL transmission cycle includes a preamble, a frame control header (FCH), a DL-MAP, a UL-MAP, and a DL burst area in order. The UL transmission period includes the ranging sub-channel and the UL burst area. The guard time for identifying the UL transmission period and the 201246858 DL transmission period is inserted into the middle portion of the frame (between the dl transmission period and the UL transmission period) and the last portion (following the ul transmission period). The transmit/receive transition gap ( ttg ) is the gap between the DL burst and the subsequent UL burst. The receive/transmit transition gap (receive/transmit transhi〇n gap; RTG) is the gap between the UL burst and the subsequent DL burst. The preamble is used between the BS and the MS for initial synchronization, cell search, and frequency offset and channel estimation. The FCH includes information about the length of the DL-MAP message and the DL-MAP code scheme. The DL-MAP is an area for transmitting DL-MAP messages. The DL-MAP message defines access to the DL channel. This implies that the DL-MAP message defines the DL channel indication and/or control information. The DL-MAP message includes a configuration change count of a downlink channel descriptor (DCD) and a BS identifier (ID). DCD Description The DL burst configuration file applied to the current MAP ^ DL · The burst configuration file refers to the characteristics of the DL 霄 频道 channel. The DCD is periodically transmitted by the BS by using a DCD message. The UL-MAP is an area for transmitting UL_MAp messages. The UL-MAP message defines access to the U]L channel. This implies that the UL-MAP message defines the UL channel indication and/or control information. The UL_MAP message includes the configuration change count of the uplink channel descriptor (UCD), and also includes the UL*-defined UL* with a valid start time. . UCD describes the UL burst configuration file. The UL burst profile indicates the characteristics of the physical channel. The UCD ° DL burst is periodically transmitted by the BS by using the 1UCD message as an area for transmitting data transmitted by Bs to ms. The UL burst is the area used to transmit the data sent by the MS. 12 201246858 The quick feedback area is included in the UL burst area of the frame. Quick feedback The area is used to transmit information. This information requires a quick response from the BS. The fast feedback area is available for CQI transmission. The position of the fast feedback area is determined by UL-MAP. The position of the quick feedback area can be a fixed position in the frame or can be a variable position. Figure 5 shows an example of an IEEE 8 〇 2.16 m frame structure. Referring to Figure 5, the superframe (SF) includes a hyperframe header (SFh) and four 5fl frames F0, F1, F2, and F3. Each frame may have the same length in the SF. Although it has been shown that each SF has a large J of 20 milliseconds (ms) and each frame has a size of 5 ms, the present invention is not limited to this case. The length of the SF, the number of frames included in the SFf, the number of SFs included in the frame, or the like may vary differently. The number of SFs included in the frame may vary differently depending on the channel bandwidth and the length of the cyclic first code (cp). The afl hub includes 8 subframes SF0, SF 1, SF2, SF3, SF4, SF5, SF6 and SF7. Each sub-frame can be used for U]: or Dl transmission. The "f" box includes a plurality of orthogonal frequency division multiplexing (OFDM) symbols or orthogonal frequency division multiple access () symbols in the time domain, and the subframes include a plurality of subcarriers in the frequency domain. 〇FDM symbol is used to represent one symbol period, and 〇fdm symbol can be % other terms according to multiple access f cases, such as 〇FDma symbols, symbols, etc. Sub-frames can be 5, 6, 7, or 9 The symbols "and" however are for illustrative purposes only and therefore, the number of OFDMA symbols included in the sub-message is not limited thereto. The number of OFDMA symbols included in the subframe 13 201246858 may be based on the channel bandwidth and the cP length. The sub-frame type may be defined according to the number of FDMA symbols included in the sub-frame. For example, the sub-frame type may be defined such that the sub-frame of type 1 includes 6 〇FDMA symbols. The sub-frame of type 2 includes 7 〇FDMA symbols, the sub-frame of type 3 includes 5 OFDMA symbols, and the sub-frame of type 4 includes 9 〇FDMa symbols. One frame may include sub-frames of the same type. , a frame may include sub-frames each having a different type. That is, the number of OFDM symbols included in each sub-frame may be the same or different in one frame, or included in a frame. At least The number of OFDMA symbols in a subframe may be different from the number of OFDMA symbols in the remaining subframes of the frame. Time division duplex (TDD) or frequency division duplex (FDD) may be applied to the frame. 'Every-sub-frame is used in the same frequency and at different times for UL or DL transmission. That is, the sub-frames included in the tdd frame are divided into UL sub-frames and DL sub-frames in the time domain. In FDD, each sub-frame is used for muscle or transmission at the same time and at different frequencies - that is, the sub-frames included in the FDD frame are divided into UL sub-frames and DL in the frequency domain. Mutual transmission. Muscle transmission and DL transmission occupy different frequency bands and can be executed simultaneously. Super frame header (SFH) can carry basic system parameters and system configuration information. SFH can be located in the super frame of the super frame. (4) The last five FDMA symbols of the first-sub-frame can be occupied. (4) can be classified into primary sfh (P-SFH) and secondary sfh (s_sfh). P can be transmitted in every _ 14 201246858 super-frames - SFH. The information transmitted in s_SFHi can be divided into 3 sub-packets, that is, 8_"1^1> Bu 8 staring 118} 52 and 1 lamp 11 SP3. Each sub-packet can be transmitted periodically and periodically. The information transmitted by S-SFH SP1, S_SFH 81 > 2 and S_SFH sp3 may differ from each other. S-SFH SP1 can be transmitted in the shortest period, and s_sfh SP3 can be transmitted in the longest period. S_SFH spi includes information about network re-entry, and the transmission period of S-SFHSP1 can be 4 〇 msaS_SFH SP2 includes information about initial network entry and network discovery, and the transmission period of s_sfh SP2 can be 80 ms. S-SFH SP3 includes other important system information' and the transmission period of S-SFH SP3 can be 16 〇 ms or 32 〇 ms. A 〇FDMA symbol includes a plurality of subcarriers, and the number of subcarriers is determined according to the size of the fast Fourier transform (fast F〇urier transf〇rm ; ). There are several types of subcarriers. The subcarrier types may include data subcarriers for data transmission, pilot subcarriers for various estimates, and null carriers for guard bands and DC carriers. The parameters used to characterize the OFDMA symbols include b w, Nused, η, G, and the like. BW represents the nominal channel bandwidth. Nused indicates the number of subcarriers in use (including DC subcarriers). n represents the sampling factor. This parameter is used to determine the subcarrier spacing and useful symbol time in conjunction with BW and Nused. G represents the ratio of CP time to useful time. Table 1 below shows the OFDMA parameters. The OFDMA parameters of Table 1 can be equally applied to the 802.163 frame structure of Figure 4.

In the following, a paging message will be described. The paging message is a medium access control (MAC) message received by the machine-to-machine (BS2) device in each paging cycle by the machine-to-machine 16 201246858 (M2M) device operating in idle mode. The paging message may indicate that there is a downlink (DL) traffic to be transmitted to a specific mobile station (MS). Alternatively, the paging message may indicate the polling of the MS and the location update request without a request for network entry. . The paging message can be broadcasted. Table 2 shows an example of a BS broadcast paging message (i.e., 'M0B-PAG_ADV message), which is a paging message of IEEE 8〇2_16e. [Table 2] Rotten bit size (bits) Description MOB PAG-ADV Message format〇{ - ... Num_Paging_Group_IDs 8 Number of paging group IDs in this message NumMACs 8 Number of MS MAC addresses for (j=〇;j&lt ; Num_MACs; j++K MS MAC Address hash 24 This hash is obtained by calculating the CRC 24 of the MS 48-bit MAC address.

When the action code of the MOB_PAG-ADV message is 17 201246858, the MOB_PAG-ADV message may request the MS to perform a location update. The MOB_PAG-ADV message may further include other fields. Table 3 shows an example of a paging advertisement message (i.e., AAI-PAG-ADV message), which is a paging message of IEEE 802.16m. [Table 3] Field size (bits) Description requirements Paging_Group_IDs bitmap L indicates that the paging information for the corresponding paging group is included in the AAI-PAG-ADV message. The length of the Paging_Group_IDs bitmap is the same as the Num_PGIDs in the PGID-Info message. L is equal to the NumPGIDs in the PGID-Info message. (i=0;i<M;i++) { Μ is equal to the number of bits in the Paging_Group_IDs bitmap image with the bit set to 1. For (j_〇;j<Num_AMSs;j++) { Num_AMSs indicates the corresponding paging group The number of paging AMSs in the middle (1 to 32). The deregistration identifier 18 is used to indicate the deregistration ID (0 to 218-1) for the AMS to be paged. If the S-SFH network configuration bit = 0b0 The MAC address hash 24 is used to identify the AMS to be called. If the S-SFH network configuration bit = = 0 bl, it exists. The paging cycle 4 is used to indicate the paging sequence for the AMS to be called. : 4 super frames 0x01 : 8 super frames 0x02 : 16 super frames 0x03 : 32 super frames 0x04 : 64 super frames 0x05 : 128 super frames 0x06 : 256 super frames if S - SFH network configuration bit = 0b0, then exists" 18 201246858

Referring to Table 3, when the value of the action code block of the AAI-PAG-ADV message is 0, the AAI-PAG-ADV message can instruct the MS to perform network re-entry. When the value of the action code field of the AAI-PAG-ADV message is 1, the AAI-PAG-ADV message can instruct the MS to perform the ranging for location update. In addition to the fields in Table 3, the AAI-PAG-ADV message may further include other fields. The MS can transmit a deregistration request message to the BS. The MS may report the release of the login request to the normal operation service provided by the BS to the BS via the deregistration request message. The IEEE 802.1 6e Deregistration Request message can be a DREG-REQ message. The IEEE 802.16m Deregistration Request message can be an AAI-DREQ-REQ message. In response to the de-registration request message, the BS may transmit the de-registration response message to Ms. Alternatively, the release of the login response message can be transmitted separately without a message to cancel the login request. The release of the login response message may indicate a change in the access status of the MS. The MS receives the unregistered response message and the action indicated in the action code is taken. The IEEE 802.1 6e release login response message can be a DREG-CMD message. The IEEE 802.16m Deregistration Response message can be an AAI-DREQ-RSP message. Table 4 shows an example of the message format of the DREG-CMD message of IEEE 802.16e. [Table 4] Field Size Description DREG-CMD Message Format 〇 { • Action code 8 TLV encoding parameter Variable - } - Table 5 shows an example of DREG-CMD/REQ message encoding for IEEE 802.16e.

The paging message can be transmitted not only to the normal MS but also to the M2M device. That is, the MOV_PAG-ADV message of Table 2 can be transmitted to the M2M device operating in the IEEE 8〇2.16e system, and the AAI-PAG-ADV message of Table 3 can be transmitted to the M2M device operating in the IEEE 802.16m system. At the same time, it is assumed that most of the M21V [devices transmit non-instantial periodic uplink (UL) data at fixed locations according to the M2M 21 201246858 application. Therefore, the paging message can be used to trigger non-instantaneous periodic UL data transmission of the fixed M2M device. Hereinafter, the proposed UL data transmission method will be described. The present invention proposes a method of triggering UL data transmission by an M2M device by using a paging message. According to the proposed UL data transmission method, the paging message may additionally include a field for triggering the UL data transmission of the M2M device. Regarding the M2M device operating in the IEEE 802.16e system, Table 7 shows an example of a MOB_PAG-ADV message including a field for triggering the UL data transfer of the M2M device. [Table 7] Block size (bits) Description MOB_PAG-ADV_Message_format() { - ...

If the value of the M2M report code block is 1, the BS can instruct the M2M device to transmit the UL data. In addition to the fields in Table 7, the MOB_PAG-ADV message can further include other fields. With respect to M2M devices operating in an IEEE 802.16m system, Table 8 shows an example of an AAI-PAG-ADV that includes a shelf for triggering UL data transfer for an M2M device. [Table 8] Field Size (Bit) Description Requirement Bu I—For (j-0; j<Num_AMSs; j++) { Num_AMSs indicates the number of paging AMSs (1 to 32) in the corresponding paging group.

Although the MOB_PAG-ADV message or the AAI-PAG-ADV message has been described above for triggering UL data transmission, the present invention is not limited to this case. In addition, the block for triggering the UL data transfer of the M2M device can be newly added as described above, or the existing action code field can be used. At the same time, the paging sequence of the existing paging message indicating the presence of the DL traffic to be transmitted to the MS may be equal to or different from the paging cycle of the paging message for triggering the UL data transmission of the M2M device proposed in the present invention. If the paging cycles of the two paging messages are different from each other, the M2M device needs to negotiate the paging cycle of each paging message when entering the idle mode. It is assumed in the following that the M2M device has a paging cycle that does not consider the purpose of paging messages. Figure 6 shows an embodiment of the proposed UL data transfer method. In step S1 00, the BS transmits the paging message to the M2M device in the idle mode. In this case, the paging message triggers the UL data transfer of the M2M device. When the M2M device is an M2M device that is used in the IEEE 802.1 6e system, the paging message may be m〇^ of Table 7. When the device is operating in the 8G2.16m_: device, the paging message can be a table kwv message. The field for triggering the UL data transfer of the M2M device can be added to the paging message. In step S110, the M2M device performs ranging to the BS to transmit muscle data. In step S120, the M2M device transmits the UL data to bs. Figure 7 shows an example of a beer listening window in accordance with the proposed UL data transfer method. A smart leaf gauge for transmitting UL data every 24 hours is shown in j7. The frame length is 2〇 milliseconds (ms), and the paging cycle is M2 sf=10.24 seconds. Therefore, the smart meter wakes up every 24 seconds to receive the AAI_PAG_ADV message transmitted from the BS. In addition, a paging cycle = 43 19744 hyperframes for 24 hours. Therefore, the BS transmits an AAI-PAG-ADV message for triggering data transmission every 8437 paging cycles. As shown in Table 8, the M2M report code block in the AAI-PAG-ADV message can be based on the AAI-PAG-ADV message transmitted in every 8437 paging cycles for triggering UL data transmission. The table can periodically transmit UL data to Bs every 24 hours. Fig. 8 shows another embodiment of the UL data transmission method proposed. Even if the BS transmits a paging message for triggering UL data transmission to the M2M device, there may be no information to be transmitted from the M2M device to the bS. In this case, the M2M device can not take action after receiving the message 25 201246858. Therefore, the M2M device can perform ranging without the BS, and can reduce the unnecessary ranging experience. However, when the M2M device does not transmit the muscle data, the BS may not be able to discern because the M2m device failed to receive the beer message without transmitting the UL data or because there is no muscle data to be transmitted and the UL data is not transmitted. Therefore, Bs will use the paging U for triggering the ul data transmission to send N times' and if there is no response from the M2M device to this situation, the M2M device can be instructed to perform the location update. This operation is to check the presence and location of the M2M device. Referring to Fig. 8', in step S20, the BS transmits a paging message for triggering UL beetle transmission to the M2M device. In step S201, the M2M device performs ranging on the BS to transmit UL data. In the next paging cycle, i.e., in step S210, the BS transmits a paging message for DL data transmission to the M2M device. In step S2n, the M2M device performs ranging to the BS to receive the dl data. In step S220, the BS transmits a paging message for triggering the ul data transmission to the M2M device. However, since there is no information to be transmitted, the M2M device does not perform ranging for the BS. In the next-page cycle, i.e., in step S230, the BS retransmits the paging message for triggering the UL data transmission to the M2M device. However, since there is no UL material to be transmitted, the M2M device does not perform ranging for the BS. If it is N 2, the B S transmits the paging message for the location update to the M2M device (i.e., S240) in the next paging cycle. The action code of the paging message used for the location update may be the location update. In step SMi, the device transmits a ranging request message 26 201246858 (rng-req message) for location update to the BS. Figure 9 shows another embodiment of the proposed UL data transfer method. Even if the BS transmits a paging message for triggering UL data transmission to the M2M device, if there is no UL material to be transmitted from the M2M device to the Bs, the M2M device can report to the Bs that there is no UL data by using the location update. In this case, the M2M device transmits the rnG-REQ message to the BS even if there is no data to be transmitted. The purpose of the RNG-REQ message can be location update. Even if there is no UL data to be transmitted, try unnecessary distance measurement. However, the BS can clearly recognize that there is no UL data to be transmitted, and the M2M device can report to Bs that there is no ul data without performing network entry. Referring to Fig. 9, in step S250, Bs transmits a paging message for triggering UL data transmission to the M2M device. At step s2M, the m2m device performs ranging on the BS to transmit UL data. In the next paging cycle, i.e., in step S260, the BS transmits a paging message for DL data transmission to the M2M device. In step S26i, the m2m device performs ranging to the BS to receive data. In step S270, the BS transmits a paging message for triggering UL/material transmission to the M2M device. However, since there is no transmitted UL negative in step S271, the M2M device transmits an RNG-REQ message indicating the UL data not transmitted by the person to 63. The purpose of the RNG-REQ message can be location update. In step S272, the RN (4) message is transmitted to the MM device in response to the _G-REq message 'Bs'. The same access control for the M2M device can be performed by using the paging message for (4) UL data transmission proposed by the present invention 27 201246858. The access control method using paging messages will be described hereinafter. The access control method proposed in the present invention can be classified into a method of controlling access of an M2M device by not transmitting a paging message, and a method of controlling access of an M2m device by using a paging message to report whether or not UL data can be transmitted. 0 1) First, the method of accessing the message by not transmitting the paging message (4) M2M is hereinafter, when the alleged paging message is not transmitted, the message may not be transmitted by itself or may imply the paging message. Transmitted, but the identifier of the M2M device is not included in the paging message. Figure 10 shows another embodiment of the proposed UL data transfer method. Due to the 'override of the road, Bs may not transmit the paging message to the M2M device during a specific paging cycle. The M2M device expects to receive paging messages in each paging cycle. However, #M2M fails to receive the paging message for triggering the transmission of the UL data, and the M2M cannot transmit the ul data to the BS. Thus 'Bs can control access to specific m2m devices. At the same time, in this case, not all M2M devices fail to receive the paging message for triggering the UL data transmission, but the specific m2m device can receive the paging message, and the other specific M2M device may not receive the paging message. . Referring to HI 1 n . u ', , , U, in step S300, the BS transmits a message for triggering the transmission of UL data to the M2M device. In step S301, the M2M device performs a distance measurement on the BS to transmit the UL data. In the next paging cycle 28 201246858, P in step S31, the BS transmits a paging message for the material delivery to the M2M device. In step S3U, the M2M device performs ranging to the BS to receive the DL data.

In step S32, a traffic overload occurs. Therefore, the BS does not transmit to the M2M device for triggering UL seed production, &

% UJ" Since the M2M device fails to receive the paging message, the ranging for the muscle data transmission is not performed. Therefore, access control for the M2M device is achieved. ^ Show another embodiment of the proposed UL data transfer method. After the transfer to the overload, Bs can not convey the paging message to the praise Gongga in the specific beer circulation. In this case, the device may expect to receive a paging message for triggering the muscle transmission in the next paging cycle and may delay the transmission of the muscle data. However, if S continues to transmit the paging message for triggering the transmission of the UL data, the muscle data to be transmitted by the = split expires, and the ranging for transmission; Therefore, in the case where the M2M device cannot receive the transmission from the BS and thus cannot satisfy the quality of service (Q〇s), it attempts to measure the BS to transmit the UL data. When the #μ2μ device does not receive a paging message during N paging cycles, the M2M device: attempts to measure the BS. For example, N can be 3. The field M2M device transmits the RNG_REQ message to the day-to-day report. The maximum number of transmissions for the paging message expires. The BS is identifiable and allows the network of the M2M device to enter the process. Paging message: The maximum number of transmissions can be applied equally to all jobs. The maximum number of transmissions for paging 5f can be defined by system parameters. 29 201246858 Alternatively, the maximum number of transmissions of paging messages may vary for each M2M device depending on the type of service. In this case, the maximum number of transmissions of the paging message can be negotiated as one of the capability values or can be defined during the DSx process. In this case, the M2M device can be configured such that the UL data is transmitted only after the message for triggering the UL data transmission is received from bs. Bs can control the overall network load by controlling the presence/absence of UL data transmission based on the load. In addition, in this case, the UL data of the M2M device generally has a delay tolerance characteristic, and thus the UL data transmission of the M2M device has no major problem. The M2M device can negotiate this characteristic of the M2M device with the BS during the login process or when entering the idle mode. Alternatively, the M2% device may negotiate the characteristics of the M2M device with Bs in each of the service flows via the DSx process. Referring to Fig. 11', in step S400, the BS transmits a paging message for triggering UL data transmission to the M2M device. In step S401, the M2M device performs ranging on the BS to transmit ul data. In step S41, a traffic overload occurs. Therefore, the BS does not transmit a paging message for triggering UL data transmission to the M2m device. Since the M2m is not able to receive the paging message, the ranging for UL data transmission is not performed. The BS does not transmit the paging message to the M2M attack during the N paging cycles, and therefore the M2M Γ罟X y* μ device does not receive the paging message during the paging cycle. When the field message fails to receive the message of the maximum number of transmissions of the paging message during the call cycle, the device attempts code ranging in step 30 201246858 S420. In step S42 1, the M2M device transmits the RNG-REQ message to the BS. In this case, the 'RNG-REQ message indicates that the maximum number of transmissions of the paging message has expired. In step S422, the RNG-RSP message can be transmitted to the M2M device in response to the RNG-REQ message 'BS. Therefore, the M2M device can continue to perform the network entry process on the BS. The maximum number of transmissions of the paging message may be included in the de-login response message. For example, the maximum number of transmissions of the paging message may be included in the DREG-CMD message, which is an IEEE 802.16e undocking response message. Alternatively, the maximum number of transmissions of the paging message may be included in the AAI-DREG-RSP message, which is an IEEE 802.16m deregistration response message. Table 9 shows an example of a DREG-CMD message including a field for indicating the maximum number of transmissions of a paging message. [Table 9]

Name Type Length Value Category M2M Device Specific Idle Mode Timer 53 3 When the M2M unit is in the idle mode, this field indicates the maximum interval length during the position update. DREG-CMD Transfer Type 54 1 Bit 0: The transfer type identifier of the UL data transfer. If the value of the bit is ObOl, the UL data is only allowed to be transmitted after receiving the paging message with the M2M report code. Bits 1 to 7: Maximum number of reserved DREG-CMD paging cycles 55 8 This indicates the maximum number of paging cycles. The M2M device can wait for the MOB-PAG-ADV message with the M2M reporting code in the maximum number of paging cycles. This is the unit of the paging cycle. DREG-CMD 31 201246858 Referring to Table 9, when the BS controls the access of the M2M device by using the paging message, the Transmission Type field and the maximum number of paging channels can be newly added to the DREG-CMD message. The M2M device can receive the DREG-CMD message, which includes the maximum number of paging cycles and the transmission type field (in the transmission type field, the M2M device is set to 1) » In this case, M2M The device may wait for a MOB_PAG-ADV message (ie, a paging message with an M2M report code) during a period corresponding to (the maximum number of X paging cycles of the paging cycle) before transmitting the UL data, the MOB-PAG-ADV message is used for Trigger UL data transfer. If the M2M device fails to receive the MOB-PAG-ADV message for triggering at least one UL data transmission during the period corresponding to (the maximum number of paging cycles of the paging cycle), the Bay|J M2M device can transmit the UL data to the BS. Instead of receiving the MOB_PAG-ADV message. Table 10 shows an example of an AAI-DREG-RSP message that includes a field indicating the maximum number of transmissions of the paging message.

If the transfer type is set to 1, it exists. ^---- ^_ Refer to Table 1 〇, when the BS controls the access of the M2M device by using paging messages, the maximum number of transmission type fields and paging cycles can be newly added to the AAI-DREG-RSP message. . The transmission period of the UL data is equal to or greater than the paging cycle. The M2M device can receive the aai-dreg-rsp message, which includes the maximum number of paging cycles and the transmission type field set to 1. In this case, the M2M device may wait for the AAI_PAG_ADV message (ie, the paging message with M2M report code = obl) during the period corresponding to (the maximum number of paging cycles 33 201246858 X paging cycles) before transmitting the UL data. The AAI-PAG-ADV message is used to trigger UL data transmission. If the M2M device fails to receive the AAI-PAG-ADV message for triggering the reduction of one UL data transmission during the period corresponding to (the maximum number of paging cycles x paging cycles), the M2M device can transmit the UL data to the BS. It is not necessary to receive AAI-PAG-ADV messages. Figure 12 shows another embodiment of the proposed UL data transfer method. In step S500, the BS transmits an AAI-DREG-RSP message to the M2M device, and the AAI-DREG-RSP message is set to the transmission type=1. In step S510, the BS transmits an AAI-pAG-ADV message to the M2M device. The AAI-PAG-ADV message is set to the M2M report code = 0 bl. Therefore, the MS can transmit the UL data to the BS. In step S520, the 'M2M device transmits the AAI-DREG-REQ message to the BS. In step S521, the BS transmits an AAI-DREG-RSP message to the M2M device, and the AAI-DREG-RSP message is set to the transmission type=1. In step S530, an access overload occurs. Therefore, the BS does not transmit an AAI-PAG-ADV message to the M2M device, and the AAI-PAG-ADV message is set to M2M report code = 〇bl. The M2M device may wait for an AAI-PAG-ADV message during a period corresponding to (the maximum number of X paging cycles of the paging cycle), the AAI-PAG-ADV message being set to M2M report code = 0 bl. If the M2M device fails to receive the AAI-PAG-ADV message during the period corresponding to (the maximum number of paging cycles of the paging cycle), the AAI-PAG-ADV message is set to 34 201246858 M2M Report Code = 〇b data The distance measurement of the transmission. The device may try to perform the method for the muscles. 2) The method for controlling the access of the device by means of the (4) call message reporting to the sink device can be used to display the device. -H* y* Ear example. When the paging message is allowed to be included, the U L prohibits the paging message of the indication of the prohibition indicator, the interval of the packet is defined and then can be received for triggering the UL ::pre-interval, and the UL data can be transmitted. Referring to FIG. 13, in step S6〇〇t, the transmitting device pair for triggering UL·data transmission is performed with a range of === ", _, in step TM , two == send paging message. In step _, the job device performs a ranging on the BS to receive the DL data. / In step S62, a traffic overload occurs. The BS transmits a paging message including the UL prohibition indicator to the M2M device. When the paging gas is received, the 'M2M device can postpone the muscle supply (4) during the predefined interval. The predefined interval can be - a paging loop. In step s63, the BS transmits a paging message for triggering the sink data transmission to the M2M device. In step S640, the M2M^f test is then tested = UL data. 1 Hunting Figure Η shows another embodiment of the proposed UL data transfer method. The BS may allow the paging message to include the UL Prohibited Time. When receiving a paging message including 35 201246858 UL non-stop day, the M2M device can wait in the UL forest and then transmit the muscle data. When τ is known, Fig. 14' In step S65, the BS transmits a paging message for triggering the UL gras transmission to the M2M device. In step S651, the M2m device performs ranging on the BS to transmit the melon data. In the next-page cycle, i.e., in step S66, the BS transmits a paging message for DL data transmission to the M2M device. At step S661, the M2M wears a ramp to perform ranging to receive DL data. And ...v in S670, traffic overload occurs. The BS transmits a paging message to the M2M device including the UL time. When a paging message is received, the device can delay the UL data transmission during the UL prohibition time. In the step coffee, the 'M2M device tries to measure the bs to transmit the sink data.
