Description

Trace data transmission method and user equipment

technical field

The present invention relates to a communication method, and in particular to a micro data transmission method and user equipment.

Background technique

With the widespread use of mobile electronic devices such as smartphones and tablet computers, the mobile data traffic of mobile electronic devices is also increasing year by year. The source of these data traffic may be generated by the user operating the application program on the mobile electronic device, such as browsing the web or chatting online, or may be caused by the background execution of the application program. Different from the data traffic caused by general voice or video transmission, the characteristics of these mobile data are that the data size is not large, and the interval between data (ie, traffic interval) may vary greatly. Data with such characteristics can be classified as Diverse Data Application (DDA) data in the standards set by the 3rd Generation Partnership Project (3GPP). This type of data can cause problems with excessive power consumption and high signaling overhead. The reason for excessive power consumption may come from the above-mentioned types of data and the time interval between the data changes too much, so that the mobile electronic device needs to keep in touch with the control node (such as a base station) in the network at all times, or in order to receive The above-mentioned types of data continue to connect/disconnect with the control node, and cannot enter the sleep mode or idle mode. The problem of excessive signaling load comes from the continuous connection/disconnection of the above-mentioned mobile electronic device with the control node. Due to the low amount of data of the above types, the amount of data required to be transmitted for such a connection operation is often far greater than the amount of data to be transmitted. Therefore, how to avoid excessive power consumption of the mobile electronic device or reduce the signaling burden between the mobile electronic device and the control node in the network when transmitting the above-mentioned DDA type data has become one of the problems urgently needed to be solved in the art.

The invention provides a user equipment, including: a transceiver and a communication protocol unit. The transceiver is used to receive/transmit signals from a control node.

Additionally, as used herein, the term "amount" is intended to include any number, including zero.

In this invention, 3GPP-like keywords or terms are only used as examples to present the inventive concepts according to the present invention; however, the same concepts presented in this invention can be applied to any other system by those skilled in the art, such as IEEE 802.11, IEEE 802.16, WiMAX, etc. Therefore, in the present invention, the term "control node" may be (for example) a base station, an evolved NodeB (Evolved NodeB, eNodeB for short), a Node B, a base transceiver system (base transceiver system, BTS for short), Access points, femtocells, repeaters, diffusers, repeaters, intermediate nodes, intermediate and/or satellite-based communication base stations, and the like.

In the following, the problems that may be caused when the user equipment transmits small data will be described first, and then the technical content of the present invention will be explained.

The message between the user equipment and the control node in the network conforms to the 3GPP long term evolution (long term evolution, referred to as: LTE) standard or advanced LTE (LTE-advanced, referred to as: LTE-A) and other communication standards Pass as an example. The working mode of the user equipment (User Equipment, referred to as: UE) includes at least two working modes of radio resource control (Radio Resource Control, referred to as: RRC) connected (CONNECTED) state and RRC idle (IDLE) state. When a UE in the network is in the RRC CONNECTED state, the control node will retain the information of the UE, such as the identification information (such as ID) and security information of the UE, and provide radio resource management (Radio Resource Management, Abbreviation: RRM). The content in RRM can include data scheduling, connection monitoring (such as modulation or adaptive coding, etc.), handover (Handover), etc. At this time, the UE can perform voice communication or data communication through the control node. action.

Due to limited radio resources and limited network load, it will be difficult for the control node to keep all UEs within its coverage in the RRC CONNECTED state at any time. Therefore, the control node will send RRC release (release) messages to release some UEs in the service range according to the UE's activity status, connection priority, or Quality of Service (QoS for short) and other parameters, so that the The UE switches to the state of RRC IDLE. When the UE switches to the RRC IDLE state, the UE only needs to periodically monitor the paging message. When the control node informs the UE that there is a corresponding call or data must be received through the paging message, the UE will establish an RRC connection with the control node again through RRC connection setup (connection setup), and after the connection is established Switch back to the RRC CONNECTED state to send and receive data from the control node normally.

The trace data described in the present invention usually has the following characteristics: the amount of data is small (for example, less than 1K byte), and compared with the data of voice communication or video communication, there may be a longer time interval between data and data , and the timing of data generation and transmission is less predictable (for example, changes according to user actions). Therefore, in the case where the downlink path (the path where the control node transmits data to the UE) has a small amount of data, the UE may repeatedly wake up from the RRC IDLE state to establish an RRC connection, and then receive RRC release and enter the RRCIDLE state, and is being woken up again...and so on. In this way, the UE may not be able to stay in the RRD IDLE for a long time, and the connection with the control node may be repeated, resulting in continuous power consumption.

On the other hand, when the UE establishes an RRC connection with the control node, at least 16 signals must be exchanged between the two, which may generate at least 176 bytes of data transmission. In addition to the delay problem that may be caused by the signal exchange of 16 transactions, compared with the micro data of less than 1K, such signal transmission leads to excessive signaling burden, which makes the overall data transmission efficiency low.

Therefore, the present invention provides a micro data transmission method and a user equipment using this method, so that the user equipment does not need to establish an RRC connection when receiving and transmitting micro data, so as to save the power consumption of the UE and reduce the establishment The problem of excessive signaling burden caused by RRC connection. The transmission method can be mainly divided into transmission on a downlink path and transmission on an uplink path (uplink path), which will be explained below with reference to the accompanying drawings and embodiments.

First, the data transmission of the uplink path will be described below. FIG. 1 is a flow chart of a micro data transmission method shown in an embodiment of the present invention. Wherein, the micro data transmission method is suitable for receiving data from the control node in the wireless network without establishing an RRC connection. Please refer to FIG. 1 , firstly in step S101, a first paging opportunity subframe in a paging frame (paging frame) is monitored in an idle mode. Then in step S102, when it is detected that an identifier included in the first paging opportunity subframe corresponds to the user equipment, a first paging message (paging message) corresponding to the first paging opportunity subframe is received. Next, in step S103, the paging message is parsed, and when the first paging message includes a trace data indicator, data is retrieved from a specified address, wherein the data is a trace data.

To put it simply, when the control node receives a small amount of data and wants to send the small amount of data to a specific UE, the control node can use the paging channel to notify the UE and transmit the small amount of data through the paging channel at the same time . FIG. 2 is a schematic diagram of the relationship between a paging frame, a paging opportunity subframe and a paging cycle shown in an embodiment of the present invention. Please refer to FIG. 2 , in a paging cycle (paging cycle) PC1 , PC2 will include multiple paging frames transmitted by the control node, such as the paging frames PF1 , PF2 shown in FIG. 2 . The paging frames (such as paging frames PF1 and PF2) respectively include paging opportunity subframes (paging opportunity/sub frame), for example, the paging frame PF1 includes at least paging opportunity subframes PO1˜PO4.

Each paging opportunity subframe (such as paging opportunity subframes PO1~PO4 in paging frame PF1) will correspond to a UE in the service range of the control node. When the control node wants to page this UE, for example, it wants to send data to this UE, the control node will place relevant information in the paging opportunity subframe corresponding to the UE. As in the above-mentioned example of the UE applied to the LTE/LTE-A network, when the UE is in the RRCIDLE state, it will periodically pass the physical downlink control channel (physical downlink control channel, PDCCH for short) at intervals of one paging cycle. ) to monitor whether any information is included in the paging opportunity subframe corresponding to itself (for example, the paging opportunity subframe PO1).

In a general paging situation, for example, when the control node intends to wake up the UE to perform RRC connection establishment and thereby transmit data, the control node will send an identifier (for example, in the LTE/LTE-A network, it is the paging radio network temporary The identifier (Paging Radio Network Temporary Identifier, referred to as: P-RNTI)) is placed in the paging opportunity subframe (such as paging opportunity subframe PO1) corresponding to this UE, and the corresponding message content (such as establishing a connection request, or update system information request) in a paging message.

When the UE detects the existence of the paging message corresponding to itself through the PDCCH channel, the UE will also receive the paging message corresponding to the P-RNTI through the Physical Downlink Shared Channel (PDSCH for short). The paging message includes the paging field corresponding to the UE (for example, using the UE ID as an identification). When the UE retrieves the paging field corresponding to itself in the paging message, it can obtain the information required by the control node. Actions, such as the above-mentioned connection establishment request, or update system information request, etc.

In this embodiment, when the control node intends to send a small amount of data to the UE, the control node places a small amount of data indicator in the paging area corresponding to the UE in the paging message. When the UE retrieves the paging area corresponding to itself in the paging message and recognizes that the paging area includes the trace data indicator, the UE can determine to obtain the trace data from the specified address. In the following, the embodiment will be used to describe how the control node will notify the UE of the specified address and the relationship between the exact location of the specified address.

FIG. 3 is a diagram showing the relationship between paging messages and trace data according to an embodiment of the present invention. Wherein in this embodiment, a small amount of data is attached to the paging message. Please refer to Figure 3. After the UE decodes the P-RNTI from the paging opportunity subframe 30 through the PDCCH411, the UE also obtains the entire paging message PM through the PDSCH312. When the UE retrieves the paging area PFD corresponding to itself in the PM , the UE can recognize that the paging area PFD includes a small amount of data indicator. In this embodiment, the control node also stores the information indicating the address in the paging area PFD when arranging the trace data indicator. For example, in this embodiment, the indication address includes the data sequence, data size, or start address and end address of the trace data SM stored in the paging message PM. When the UE recognizes that the paging area PFD includes the micro data indicator, the UE also searches the designated address of the micro data SM in the paging area PFD, and retrieves the micro data from the paging message PM according to the designated address.

It is worth noting that a single paging opportunity subframe 30 can correspond to multiple UEs (with different P-RNTIs and different paging area PFDs in the paging message PM), this embodiment adds a small amount of data to the paging message The approach in PM actually enables the micro data to be transmitted to UEs corresponding to the subframe 30 of the same paging opportunity in a broadcast state. Because micro data usually has a certain security mechanism, it will not generate privacy/security issues, but there is still the problem of receiving unnecessary data every time the paging message PM is received (that is, the extra data caused by micro data) burden).

FIG. 4 is a diagram showing the relationship between paging messages and trace data according to another embodiment of the present invention. The difference from the embodiment shown in FIG. 3 is that the specified address for storing the trace data is located on another frame. In this embodiment, after the UE decodes the P-RNTI from the paging opportunity subframe 40 through the PDCCH411, the UE also obtains the paging message PM through the PDSCH412. When the UE retrieves the paging area PFD corresponding to itself in the PM , when it is recognized that the paging area PFD includes the micro data indicator, the UE also searches the designated address of the micro data SM in the paging area PFD. Since in this embodiment, the designated address is located on the next subframe 41, the UE will receive the next subframe 41 after receiving the paging opportunity subframe 40, and will receive the next subframe 41 according to the information of the designated address stored in the paging area PFD. In the next subframe 41 the trace data SM is retrieved.

The next subframe 41 may be any paging opportunity subframe, or a subframe transmitted on a downlink path, as long as the control node indicates it in the information of the specified address. For example, the next subframe 41 may be a subframe that provides a paging opportunity or a subframe that only provides downlink path data. In this embodiment, the next subframe 41 and the paging opportunity subframe 40 are located in the same frame, and the next subframe 41 is the paging opportunity subframe at the next time point of the paging opportunity subframe 40, but in implementation The subframe including the designated address can be set according to the actual situation, and the present invention is not limited to the above.

In addition, because the control node can arrange the corresponding UEs in each paging opportunity subframe, the control node can reduce the number of UEs corresponding to the paging opportunity subframe 40 where the micro data SM is placed, or place multiple micro data SMs in a centralized manner. in the same paging opportunity subframe (eg, paging opportunity subframe 40). In this way, in the embodiment shown in FIG. 3 , the extra burden caused by the small amount of data SM on other UEs can be avoided. However, in this embodiment, the UE must receive the next subframe 41 at the next time point (or after several time points) outside the subframe 40 for receiving the paging opportunity. In this way, compared with the For example, the trace data in this example has a slight time delay. But basically users are more tolerant to the time delay of trace data signals, and the above-mentioned time delay should not cause troubles for users.

Except for the embodiments shown in Figure 3 and Figure 4, in an embodiment of the present invention, the control node includes the information of the specified address in the RRC release message, when the UE recognizes the trace data indicator from the paging area PFD , the trace data can be retrieved directly from the specified address. Compared with the above-mentioned embodiments shown in Fig. 3 and Fig. 4, the advantage of such setting is that the data size of the paging message (such as the paging message PM shown in Fig. 3 and 4) can be reduced, corresponding to the same paging opportunity The UEs in the subframe all reduce the data overhead. However, compared with the embodiments shown in FIG. 3 and FIG. 4 , such an approach is less flexible. Because in this embodiment, the information of the specified address is included in the RRC release message, it means that before the next time the UE establishes an RRC connection with the control node, the control node must transmit a small amount of data to the UE with the specified address, and Fig. 3 1. The setting of the embodiment shown in FIG. 4 does not have this restriction, and when a small amount of data needs to be transmitted, the designated address of the small amount of data can be dynamically adjusted.

To put it simply, no matter which of the above-mentioned address-specific information transmission methods is used with the location of the trace data, the UE can receive the corresponding trace data from the control node simply by monitoring the corresponding paging opportunity subframe. , without establishing an RRC connection with the control node.

In the following, the micro data transmission of the uplink path (ie, the transmission of micro data from the UE to the control node) will be described. Generally speaking, when the UE wants to transmit data (audio and video data or the above-mentioned micro data), it needs to establish an RRC connection with the control node before transmitting the data. However, in the present invention, the control node will include a specific preamble in the RRC release message when transmitting the RRC release message.

When the UE wants to transmit a small amount of data to the control node, the UE can transmit the specific preamble signal to the control node through a Physical Random Access Channel (PRACH). When the control node receives the specific preamble on the PRACH instead of the preamble normally transmitted by RRC establishment, the control node can identify that the UE transmitting the specific preamble intends to transmit a small amount of data. Therefore, the control node may send a random access (RA) response message to the UE. However, the RA response message at this time is not to inform the UE that the RRC connection can be made with it, but to inform the UE that a small amount of data can be transmitted. After the UE receives the RA response message, the UE transmits the aforementioned trace data in the RRC connection establishment request message to the control node. Since the control node recognizes that the UE only intends to send a small amount of data rather than sending the RRC connection establishment request message for establishing an RRC connection, the control node retrieves the small amount of data from the RRC connection establishment request message and sends it to the corresponding network. object.

In this way, every time the UE wants to send a small amount of data to the control node, the UE does not need to establish an RRC connection with the control node, making the RRC connection require at least 16 signaling burdens (including at least 176bytes of additional data) It can be saved, which not only makes the transmission more efficient, but also reduces the time delay caused by establishing the RRC connection. And when the UE is an electronic device such as a smart meter, which will periodically transmit a small amount of data through a machine type communication (MTC) network, the above-mentioned signaling burden that can be saved is even more considerable.

It should be noted that since the number of specific preamble signals is limited, and the UEs served by a single control node may also include many UEs that need to transmit a small amount of data, in an embodiment of the present invention, the above-mentioned specific preamble signals are time-sensitive and also It is semi-reserved. After the time limit for the UE to use the specific preamble has expired, the UE cannot transmit the trace data in the above-mentioned way, and may have to transmit the above trace data after re-establishing the RRC connection, and the next time it receives the RRC release message, it will be reacquired A specific leading signal within the time limit.

FIG. 5 is a timing flow chart of the micro data transmission system shown in an embodiment of the present invention, which provides a relatively complete signal transmission process of the micro data transmission method in the present invention. On the other hand, the micro data transmission system 10 shown in FIG. 5 can also be directly integrated into existing systems without any conflict with existing data transmission methods.

Please refer to FIG. 5 , where the trace data transmission system 10 includes a control node 110 and a UE 120 . Wherein, before performing step S501 , UE 120 may need to communicate with control node 110 , for example, to transmit a service that requires control node 110 to provide a small amount of data transmission. After the control node 110 agrees to provide the micro data transmission service, the control node 110 and the UE 120 can further focus on the packet size of the micro data, the transmission period or interval, the absolute timing of the transmission (absolute timing) and/or the robustness (robustness) ) requirements and other conditions to communicate.

When the control node 110 completes the communication of the above conditions and needs to release the RRC connection with the UE 120, the control node 110 will send an RRC release message to the UE 120 (step S501), and when the UE receives the RRC release message, Then switch to idle mode (ie, RRC IDLE state) to periodically monitor paging frames (step S502). It is worth noting that the control node 110 includes part of the information for micro data transmission into the RRC release message, such as the specific preamble, the expiration date of the specific preamble, or even the designated address of the micro data of the downlink path etc., vary with different implementations.

When the UE120 is in the idle mode, and the control node 110 receives the trace data corresponding to the UE120 from the network (step S503), the control node 110 transmits the message corresponding to the paging opportunity subframe of the UE120 and the trace data to the UE120 (step S504) As for the transmission method of the trace data, reference may be made to the above-mentioned embodiments (for example, the implementation manners in FIGS. 3-4 ), and details will not be described here. When the UE 120 successfully retrieves a small amount of data from the specified address, the UE 120 transmits an acknowledgment (Acknowledgment, ACK for short) signal including a specific preamble signal to the control node 110 . And when the UE 120 fails to successfully retrieve the trace amount of data from the specified address, the UE 120 sends a negative acknowledgment (Negative Acknowledgment, NACK for short) signal to the control node 110 (step S505 ).

It should be noted that UE 120 may transmit the above-mentioned ACK or NACK signal through PRACH. However, the specific preamble included in the ACK or NACK signal may be the same as or different from the specific preamble used for micro data transmission on the uplink path. If the specific preamble included in the ACK or NACK signal is different from the specific preamble of the small amount of data transmission on the uplink path, the UE 120 may also obtain the specific preamble from the RRC release message.

In another embodiment of the present invention, the ACK or NACK signal does not include the above-mentioned specific preamble signal, but is transmitted using a specific time slot (slot) in the PRACH. In yet another embodiment of the present invention, the ACK or NACK signal includes the above-mentioned specific preamble signal, and is transmitted using a specific time slot (slot) in the PRACH. Similarly, the relevant information of the specific time slot specified by the ACK/NACK can also be included in the RRC release message and sent to the UE120.

Please refer to FIG. 5 again, when the control node 110 receives the ACK signal from the UE 120, it indicates that the downlink path data transmission is completed. When the control node 110 receives a NACK signal from the UE 120, or does not receive any ACK or NACK signal returned from the UE 120 within a preset time after transmitting the trace data, the control node 110 will judge the trace data and The transfer is not complete. Therefore, the control node 110 sends an RA response message to the UE 120 to inform the UE 120 that the control node 110 is about to retransmit the above-mentioned micro data, and retransmits the micro data to the UE 120 by using the transmission method such as the above step S504 (steps S506, S507). In other words, steps S506 and S507 will not be executed when the micro data transmission is successful.

Steps S511-S515 are the flow of micro data transmission on the uplink path. Please continue to refer to FIG. 5. When UE120 generates a small amount of data (for example, through user manipulation, or periodically) (step S511), UE120 sends a specific preamble signal to control node 110 through PRACH to notify control node that UE120 wants to Send a small amount of data. When the PRACH is congested or collided, the UE 120 automatically backs off (auto back-off) for a preset time point, and then retransmits (step S512). After the control node 110 receives the above-mentioned specific preamble signal, the control node 110 may send an RA response message to the UE 120 to notify the UE 120 that the micro data can be transmitted (step S513 ). After the UE 120 receives the RA response message, the UE 120 will send the above-mentioned small amount of data to the control node 110 (for example, include the small amount of data in the RRC connection establishment request message) (step S514 ). Since the control node 110 has identified according to the specific preamble that the UE 120 only intends to transmit a small amount of data, the control node 110 retrieves the small amount of data. If the control node 110 successfully retrieves the trace data, it returns an ACK signal to the UE 120 (step S515 ). And when the control node 110 fails to retrieve the trace amount of data, the control node 110 returns a NACK signal to the UE 120 . When the UE 120 receives the NACK signal or does not receive any ACK or NACK signal returned from the control node 110 within a predetermined time after transmitting the small amount of data, the UE 120 repeats the above steps S512-514 to retransmit the small amount of data.

The present invention 1 provides a user equipment suitable for the above micro data transmission method. Fig. 6 is a functional block diagram of user equipment according to an embodiment of the present invention. Referring to FIG. 6 , UE60 includes a transceiver 610 and a communication protocol unit 620 . The transceiver 610 is used for receiving/transmitting signals from a control node. The communication protocol unit 620 is coupled to the transceiver 610 and receives/transmits signals through the transceiver 610 . Wherein, the communication protocol unit 620 monitors the first paging opportunity subframe in the paging frame through the transceiver in the sleep mode or the idle mode of the user equipment 60 . When the communication protocol unit 620 detects that the first paging opportunity subframe includes an identifier corresponding to the user equipment, the communication protocol unit 620 receives the first paging message corresponding to the first paging opportunity subframe through the transceiver 610 . The communication protocol unit 620 parses the paging message. When the first paging message includes a trace data indicator, the communication protocol unit 620 retrieves data from a specified address, wherein the data is trace data. As for the detailed implementation manner of the UE60, reference may be made to the above-mentioned embodiments shown in FIGS. 1 to 5 , which will not be repeated here.

In a practicable manner, the communication protocol unit 620 receives the first paging message through the transceiver 610, and retrieves the specified address from a paging area corresponding to the identifier in the first paging message; and, communicating The agreement unit 620 retrieves the data from the specified address in the first paging message according to the specified address.

In another possible implementation, the communication agreement unit 620 retrieves the specified address from the paging area corresponding to the identifier in the first paging message; and the communication agreement unit 620 controls the transceiver 610 to receive a second paging paging message, the data is retrieved from the specified address in the second paging message according to the specified address, wherein a second paging opportunity subframe corresponding to the second paging message is located at the same location as the first paging opportunity subframe in the paging frame.

Wherein, the identifier is a paging radio network temporary identifier, and the communication protocol unit 620 controls the transceiver 610 to detect whether the first paging opportunity subframe includes the identifier through the PDCCH.

The communication protocol unit 620 may also control the transceiver 610 to receive the first paging message corresponding to the subframe of the first paging opportunity through the PDSCH.

On the basis of the above, when retrieving the data is successful, the communication agreement unit 620 controls the transceiver 610 to transmit a response signal to the control node through the PRACH; The PRACH transmits a negative acknowledgment signal to the control node. Wherein, the acknowledgment signal and the negative acknowledgment signal include a specific preamble signal, and/or are transmitted through a specified time slot in the physical random access channel.

When the UE 60 receives an RRC connection release message in a connected mode, the communication agreement unit 620 switches the UE 60 to the idle mode. Wherein, the RRC connection release message includes the designated address.

Further, the RRC connection release message may include a specific preamble signal, and the UE60 may further include: a processing unit in the user equipment generates a transmission data and transmits it to the communication protocol unit 620, wherein the data is micro data; The communication protocol unit 620 controls the transceiver 610 to transmit the specific preamble signal to the control node; and, when the communication protocol unit 620 receives a connection response from the control node through the transceiver 610 in response to the specific preamble signal, the transmission includes A connection establishment request of the data to the control node.

It should also be noted that the communication protocol unit 620 may control the transceiver 610 to transmit the specific preamble to the control node through a physical random access channel; and, the connection establishment request is an RRC connection establishment request.
