Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a low-power communication method and a communication terminal. Background Art

[0002] In mobile communication systems, many IoT devices and other mobile communication terminals are powered by batteries, especially in environments where it is difficult to replace or charge batteries. However, many IoT applications do not require frequent data transmission, such as environmental monitoring and asset tracking. Therefore, it is necessary to reduce power consumption as much as possible when frequent communication is not required to extend battery life. The existing low-power modes mainly include DRX (Discontinuous Reception), eDRX (Extended idle-mode DRX cycle), and PSM (Power Saving Mode). DRX provides basic discontinuous reception function, and the terminal only monitors downlink paging in a specific time period. eDRX extends the DRX cycle and is more suitable for IoT devices that do not need to receive data frequently. PSM sets an activation timer to monitor downlink paging, allowing the device to enter a dormant state to further reduce power consumption. PSM can also be used in combination with DRX and eDRX.

[0003] However, in the existing low power consumption mode, whenever the terminal switches from the connected state to the idle state, an activation timer is started to monitor downlink paging, even if there is no downlink paging, which increases power consumption and avoids unnecessary power consumption.

[0004] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0005] The embodiments of the present application provide a low-power communication method and a communication terminal, so as to at least solve the technical problem that unnecessary power consumption still exists in the power-saving working mode of the relevant communication terminal.

[0008] Optionally, before sending a non-access layer message to a core network element, the method further includes: establishing a radio resource control connection with a base station, and establishing a non-access layer signaling connection with the core network element through the base station to enter an ECM-CONNECTED state.

[0009] Optionally, sending a non-access layer message to a core network element includes: sending a tracking area update request message to the core network element for requesting to modify the duration of an extended activation timer corresponding to a power saving mode, wherein the target information element carried by the tracking area update request message is used to instruct the terminal to execute the first working mode.

[0010] Optionally, a tracking area update accept message including an updated duration of the extended activation timer fed back by the core network is received.

[0011] Optionally, sending a non-access layer message to a core network element includes: sending a service request message for reporting data to the core network element, wherein a target information element carried by the service request message is used to instruct the terminal to execute the first working mode.

[0012] Optionally, entering the ECM-IDLE state from the ECM-CONNECTED state includes: releasing a radio resource control connection with the base station, and entering the ECM-IDLE state.

[0013] According to another aspect of an embodiment of the present application, a communication terminal is also provided, including: a communication module, used to send a non-access layer message to a core network network element when in an ECM-CONNECTED state, wherein the non-access layer message carries a target cell for indicating a low power consumption working mode of the terminal; an execution module, used to execute a low power consumption working mode corresponding to the target cell when entering an ECM-IDLE state from the ECM-CONNECTED state, wherein the low power consumption working mode includes: a first working mode of directly entering a power saving mode working state without starting an activation timer, or a second working mode of starting an activation timer and monitoring downlink paging, and entering a power saving mode working state after the activation timer times out.

[0014] According to another aspect of an embodiment of the present application, a computer program product is further provided, the computer program product comprising: a computer program, wherein when the computer program is executed by a processor, the above-mentioned low-power consumption communication method is implemented.

[0015] According to another aspect of an embodiment of the present application, an electronic device is further provided, the electronic device comprising: a memory and a processor, wherein a computer program is stored in the memory, and the processor is configured to execute the above-mentioned low-power communication method through the computer program.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] In order to better understand the embodiments of the present application, some nouns or terms that appear in the description of the embodiments of the present application are first translated and explained as follows:

[0027] DRX: An energy-saving technique used in wireless communication systems, especially in mobile communication networks. It allows mobile devices to enter a low-power state when not transmitting data, thereby saving battery power. DRX works by waking up the device periodically to receive data, rather than continuously remaining in a high-power receiving state. In DRX mode, the mobile device negotiates a DRX cycle with the network, which defines how often the device needs to check for new data packets. During the DRX cycle, the device goes to sleep and only briefly activates the receiver at specific wake-up moments to check for data. If there is no data, the device goes to sleep again until the next wake-up moment. If there is data, the device remains active to receive the data and may then enter DRX mode again. Specifically, for the DRX mode, the terminal only monitors the PDCCH (Physical Downlink Control Channel) channel at the location where PO (Paging Occasion) appears within a DRX cycle; if the PDCCH carries P-RNTI (Paging-Radio Network Temporary Identifier), the data on the PDSCH (Physical Downlink Shared Channel) parameters indicated on the PDCCH are received; if the PDCCH does not carry P-RNTI, there is no need to monitor the PDSCH channel, but to enter sleep. P-RNTI is an identifier used to identify the paging message sent by the core network element. This method combined with DRX and eDRX can further reduce power consumption on the basis of the power saving mode working state.

[0028] eDRX: An extended form, eDRX extends the DRX cycle, allowing the device to check for new data packets at longer time intervals, thereby further reducing power consumption. eDRX increases the length of the DRX cycle and reduces the number of device wake-ups, thereby significantly reducing power consumption. Figure 2 As shown, the DRX cycle is 2.56 seconds, and the longest eDRX cycle is 2.92 hours.

[0029] PSM power saving mode: a low-power technology used in mobile communication systems, especially widely used in IoT devices. PSM allows devices to enter a deep sleep state when frequent communication is not required, thereby significantly extending battery life. In power saving mode, the device is in a deep sleep state most of the time, turns off the wireless transceiver, and does not listen to the network's paging channel. The device will wake up briefly at a specific time point according to the configured paging cycle and listen to the network's paging channel to check if there is a paging message. The paging cycle refers to the time interval for the device to listen to the network's paging channel in PSM mode. T3324 is an activation timer that controls the activation cycle of the device in PSM mode. If the device needs to listen to downlink paging, this timer will be started. T3412 is also a timer that defines the maximum stay time of the device in PSM mode and when it should wake up to check if there is a paging message. Such as Figure 3 As shown, after RRC is established, the terminal sends a periodic (TAUPeriodic Tracking Area Update) request message to the network at a preset time interval to update its location information. After the RRC connection is released, the timer T3324 is activated to monitor paging Paging, and after timeout, it enters the power saving mode PSM low power consumption state.

[0030] The combination of PSM mode and DRX / eDRX is as follows Figure 4 As shown, in Figure 4 In the case of RRC release, during the operation of the activation timer T3324 of the power saving mode PSM function, the downlink paging is monitored in DRX mode. After the activation timer T3324 times out, the low power consumption mode is entered, which can further reduce power consumption on the basis of the power saving mode PSM. Similarly, downlink paging can also be monitored in DRX mode.

[0031] Example 1

[0032] According to an embodiment of the present application, a low-power communication method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0033] Figure 1 is a flow chart of a low-power communication method provided according to an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0034] Step S102, when in the ECM-CONNECTED state, sending a non-access layer message to a core network element, wherein the non-access layer message carries a target information element for indicating a low power consumption working mode of the terminal;

[0035] Step S104, when entering the ECM-IDLE state from the ECM-CONNECTED state, execute the low-power working mode corresponding to the target signal element, wherein the low-power working mode includes: not starting the activation timer, and directly entering the first working mode of the power saving mode working state, or starting the activation timer and monitoring the downlink paging, and entering the second working mode of the power saving mode working state after the activation timer times out.

[0036] The following describes each step of the low-power communication method in conjunction with a specific implementation process.

[0037] In the existing technology, regardless of whether the power saving mode is started simultaneously with the DRX or eDRX function, each time the terminal switches from the ECM-CONNECTED state to the ECM-IDLE state, the T3324 activation timer will be started to monitor the downlink channel paging, but there may not be downlink paging at this time, especially in the specific scenario where the IoT terminal simply reports data and modifies the PSM timer duration, most of the T3324 operation period is invalid monitoring, so there is room for optimization. In order to further reduce power consumption, the present application proposes to flexibly select and execute two working modes when the terminal changes from the ECM-CONNECTED state to the ECM-IDLE state. For the selection and control of the two modes, the present application uses specific signal element symbols to control the low-power working mode executed by the terminal. Among them, the low-power working mode includes a first working mode and a second working mode. The first working mode is: do not start the activation timer and directly enter the power saving mode working state; the second working mode is: start the activation timer and monitor the downlink paging, and enter the power saving mode working state after the activation timer times out.

[0038] As an optional implementation, the state of the target cell used to indicate the low power consumption working mode of the terminal can be: the cell identifier is G-, the cell name is the power saving mode optimization switch, the type / reference is the power saving mode optimization switch, the existence is an optional network element, the format is type-value, and the length is 1 byte; wherein, the upper four bits of the target cell are the cell identifier, the lowest bit is the valid identifier, and the remaining three bits are spare; if the valid identifier is 0, it indicates that the power saving mode optimization switch is not turned on, and the second working mode is executed; if the valid identifier is 1, it indicates that the power saving mode optimization switch is turned on, and the first working mode is executed. Table 1 provides the octet format of the target cell.

[0039] Table 1

[0040]

[0041] The Flag in Table 1 is a valid identification bit. As shown in Table 2, the valid identification Flag is located at the lowest 1 bit and has two valid values ​​0 and 1. The Flag value 0 indicates that the power saving mode optimization switch is not turned on, and the second working mode is executed according to the current protocol standard, that is, after the ECM-CONNECTED state is transferred to the ECM-IDLE state, the activation timer is started, and downlink paging is monitored. After the activation timer times out, the power saving mode working state is entered, and the terminal stops monitoring downlink paging; the Flag value 1 indicates that the power saving mode optimization switch is turned on, that is, after the ECM-CONNECTED state is transferred to the ECM-IDLE state, the activation timer is not started, but the power saving mode working state is directly entered, and the terminal immediately stops monitoring downlink paging.

[0042] Table 2

[0043]

[0044] When the terminal needs to modify the extended timer duration of the power saving mode to further control the period of sending the tracking area update request message and the subsequent timing of monitoring downlink paging, the terminal can send a tracking area update request message carrying a target information element to the core network element.

[0045] Since the terminal is in the ECM-IDLE state, there is no complete connection between the terminal and the network, and it only maintains a basic connection with the core network for receiving paging messages, etc. When the terminal needs to establish a complete connection with the core network, it will initiate an RRC (Radio Resource Control) connection establishment process. This connection allows the terminal to exchange control information with the base station. Through the base station, the terminal establishes a non-access layer signaling connection with the core network element and enters the ECM-CONNECTED state. In this state, the terminal can send and receive data normally.

[0046] Only after a complete connection is established can the terminal exchange non-access layer messages with the network and configure the low power mode. If the terminal is still in the ECM-IDLE state, it cannot send non-access layer messages and cannot configure the low power mode. Therefore, the terminal entering the ECM-CONNECTED state is the basis for implementing the low power mode configuration.

[0047] As an optional implementation manner, after the connection is established, the terminal sends a tracking area update request message carrying a target cell to the core network element in the ECM-CONNECTED state, and the message content is shown in Table 3.

[0048] Table 3 Tracking area update request message content

[0049]

[0050] In the message content shown in Table 3, if the terminal decides to start the first working mode of this application after the current process ends, the target information element of the power saving mode optimization switch configuration is carried in the tracking area update request message, and the Flag field shown in Table 1 is filled in with 1; if the terminal decides not to start the first working mode after the current process ends, and executes the second working mode according to the protocol standard power saving mode, the target information element is carried in the tracking area update request message, and the Flag field shown in Table 1 is filled in with 0.

[0051] As shown in Table 3, in other optional information elements, T3324 is an activation timer used to control the activation cycle of the device in the power saving mode. If the device needs to monitor downlink paging, this timer will be started. T3412 is also a timer that defines the maximum stay time of the terminal in the power saving mode and when it should wake up to check whether there is a paging message. If the terminal needs to modify the timer value, the corresponding field can be modified in the message content shown in Table 3.

[0052] As an optional implementation, when the terminal sends an update area request message, it is also necessary to receive a tracking area update accept message including the updated duration of the extended activation timer fed back by the core network.

[0053] Optionally, when the terminal has data to report, the terminal may also send a service request message for reporting data to the core network element, and the service request message carrying the target cell is shown in Table 4. It should be noted that, consistent with the premise of sending the area update request message carrying the target cell, the terminal can send the service request message only after a complete connection is established.

[0054] Table 4 Service request message content

[0055]

[0056] In Table 4, if the terminal decides to enter the first working mode after the current process ends, the target information element shown in Table 1 is carried in the service request message, and the Flag field of the target information element is filled in with 1; if the terminal decides to execute the second working mode after the current process ends, the service request message carries the target information element, and the Flag field is filled in with 0.

[0057] It should be noted that, generally, when a terminal reports user data in a one-way reporting manner, the server does not need to return a message. Therefore, if the terminal sends a service request message, the core network element does not need to feedback a message.

[0058] Optionally, when the terminal releases the radio resource control connection with the base station, the terminal enters the ECM-IDLE state from the ECM-CONNECTED state, and at this time the terminal completely executes the low power consumption working mode indicated in the non-access layer message sent above.

[0059] This application mainly indicates the working mode of the terminal by the target information element sent by the terminal when entering the ECM-IDLE state from the ECM-CONNECTED state, so as to avoid unnecessary monitoring of the terminal when entering the power saving mode working state. Regardless of the working mode, the terminal will also regularly monitor the downlink channel in the power saving mode working state. If the terminal monitors the downlink paging signal during the activation timer, it will exit the power saving mode working state, establish an RRC connection and enter the ECM-CONNECTED state. This mechanism ensures that the terminal can quickly respond to the network's paging message when needed while maintaining low power consumption.

[0060] In an embodiment of the present application, when the terminal is in the ECM-CONNECTED state, the terminal sends a non-access layer message to the core network element, wherein the non-access layer message carries a target cell for indicating the low-power working mode of the terminal; when the terminal enters the ECM-IDLE state from the ECM-CONNECTED state, the terminal executes the low-power working mode corresponding to the target cell, wherein the low-power working mode includes: not starting the activation timer, directly entering the first working mode of the power saving mode working state, or starting the activation timer and monitoring the downlink paging, and entering the second working mode of the power saving mode working state after the activation timer times out. By sending a non-access layer message carrying a target cell indicating the low-power working mode to the core network element in the ECM-CONNECTED state, the terminal can flexibly select a suitable low-power working mode when entering the ECM-IDLE state, thereby solving the technical problem that the power saving working mode of the relevant communication terminal still has unnecessary power consumption.

[0061] Example 2

[0062] According to an embodiment of the present application, a communication terminal for implementing the low-power communication method in Embodiment 1 is also provided. Figure 5 As shown, the low-power communication terminal at least includes: a communication module 51 and an execution module 52, wherein:

[0063] The communication module 51 is used to send a non-access layer message to a core network element when in the ECM-CONNECTED state, wherein the non-access layer message carries a target cell for indicating a low power consumption working mode of the terminal;

[0064] The execution module 52 is used to execute a low-power working mode corresponding to the target cell when entering the ECM-IDLE state from the ECM-CONNECTED state, wherein the low-power working mode includes: not starting the activation timer and directly entering the first working mode of the power saving mode working state, or starting the activation timer and monitoring the downlink paging, and entering the second working mode of the power saving mode working state after the activation timer times out.

[0065] The functions of each module of the communication terminal are described below in conjunction with a specific implementation process.

[0066] In the existing technology, regardless of whether the power saving mode is started simultaneously with the DRX or eDRX function, each time the terminal switches from the ECM-CONNECTED state to the ECM-IDLE state, the T3324 activation timer will be started to monitor the downlink channel paging, but there may not be downlink paging at this time, especially in the specific scenario where the IoT terminal simply reports data and modifies the PSM timer duration, most of the T3324 operation period is invalid monitoring, so there is room for optimization. In order to further reduce power consumption, the present application proposes to flexibly select and execute two working modes when the terminal changes from the ECM-CONNECTED state to the ECM-IDLE state. For the selection and control of the two modes, the present application uses specific signal element symbols to control the low-power working mode executed by the terminal. Among them, the low-power working mode includes a first working mode and a second working mode. The first working mode is: do not start the activation timer and directly enter the power saving mode working state; the second working mode is: start the activation timer and monitor the downlink paging, and enter the power saving mode working state after the activation timer times out.

[0067] As an optional implementation, the state of the target cell used to indicate the low power consumption working mode of the terminal can be: the cell identifier is G-, the cell name is the power saving mode optimization switch, the type / reference is the power saving mode optimization switch, the existence is an optional network element, the format is type-value, and the length is 1 byte; wherein, the upper four bits of the target cell are the cell identifier, the lowest bit is the valid identifier, and the remaining three bits are spare; if the valid identifier is 0, it indicates that the power saving mode optimization switch is not turned on, and the second working mode is executed; if the valid identifier is 1, it indicates that the power saving mode optimization switch is turned on, and the first working mode is executed. The octet format of the target cell is as shown in Table 1 above.

[0068] When the terminal needs to modify the extended timer duration of the power saving mode to further control the period of sending the tracking area update request message and the subsequent timing of monitoring downlink paging, the communication module 51 can send a tracking area update request message carrying the target information element to the core network element.

[0069] Since the terminal is in the ECM-IDLE state, there is no complete connection between the terminal and the network, and it only maintains a basic connection with the core network for receiving paging messages, etc. When the terminal needs to establish a complete connection with the core network, it will initiate an RRC (Radio Resource Control) connection establishment process. This connection allows the terminal to exchange control information with the base station. Through the base station, the terminal establishes a non-access layer signaling connection with the core network element and enters the ECM-CONNECTED state. In this state, the terminal can send and receive data normally.

[0070] Only after a complete connection is established can the terminal exchange non-access layer messages with the network and configure the low power mode. If the terminal is still in the ECM-IDLE state, it cannot send non-access layer messages and cannot configure the low power mode. Therefore, the terminal entering the ECM-CONNECTED state is the basis for implementing the low power mode configuration.

[0071] As an optional implementation manner, after the connection is established, the communication module 51 sends a tracking area update request message carrying a target information element to the core network element in the ECM-CONNECTED state.

[0072] In the message content of the tracking area update request message carrying the target cell, if the execution module 52 starts the first working mode of the present application after the current process ends, the target cell of the power saving mode optimization switch configuration is carried in the tracking area update request message, and the Flag field shown in Table 1 is filled in with 1; if the execution module 52 does not start the first working mode after the current process ends, and executes the second working mode according to the protocol standard power saving mode, the target cell is carried in the tracking area update request message, and the Flag field shown in Table 1 is filled in with 0.

[0073] Optionally, when the non-access layer message sent by the terminal is an update area request message, it is also necessary to receive a tracking area update accept message including the updated duration of the extended activation timer fed back by the core network.

[0074] Optionally, when the terminal has data to report, the communication module 51 may also send a service request message for reporting data to the core network element, and the target information element carried in the service request message is also used to instruct the terminal to execute the first working mode.

[0075] In the service request message carrying the target cell, if the execution module 52 enters the first working mode after the current process ends, the target cell shown in Table 1 is carried in the service request message, and the Flag field of the target cell is filled in with 1; if the execution module 52 executes the second working mode after the current process ends, the service request message carries the target cell, and the Flag field is filled in with 0.

[0076] It should be noted that, generally, when a terminal reports user data in a one-way reporting manner, the server does not need to return a message. Therefore, if the terminal sends a service request message, the core network element does not need to feedback a message.

[0077] Optionally, when the terminal releases the radio resource control connection with the base station, the terminal enters the ECM-IDLE state from the ECM-CONNECTED state, and at this time the terminal completely executes the low power consumption working mode indicated in the non-access layer message sent above.

[0078] This application mainly indicates the working mode of the terminal by the target information element sent by the terminal when entering the ECM-IDLE state from the ECM-CONNECTED state, so as to avoid unnecessary monitoring of the terminal when entering the power saving mode. Regardless of the working mode, the terminal will also regularly monitor the downlink channel when in the power saving mode. If the terminal monitors the downlink paging signal during the activation timer, it will exit the power saving mode, establish an RRC connection and enter the ECM-CONNECTED state. This mechanism ensures that the terminal can quickly respond to the network's paging message when needed while maintaining low power consumption.

[0079] It should be noted that each module in the communication terminal of the embodiment of the present application corresponds one by one to each implementation step of the low-power communication method in Example 1. Since a detailed description has been given in Example 1, some details not reflected in this embodiment can be referred to Example 1 and will not be repeated here.
