Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, device, terminal and equipment for processing a terminal idle state. Background Art

[0002] With the development of the Internet of Things, reducing terminal power consumption has always been a key issue in the field of IoT terminals. After entering the connected state and sending data, some existing IoT terminals hope to return to the idle state as soon as possible in order to reduce power consumption as much as possible.

[0003] However, the current network terminal location update process from the connected state to the idle state is controlled by the cell inactivation timer: the base station starts the inactivation timer, and sends the radio resource control (RRC) connection release (RRC-Connection-Release) only after the inactivation timer expires. In this way, the terminal consumes power during the setting time of the inactivation timer. Summary of the invention

[0108] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0109] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0110] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0111] Additionally, the terms "system" and "network" are often used interchangeably herein.

[0112] In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0113] like Figure 1 As shown, a terminal idle state processing method according to an embodiment of the present invention is applied to a terminal, including:

[0114] Step 101, after a terminal in a connected state completes data transmission, the terminal is switched from a connected state to an idle state;

[0115] Step 102: Send a first message to a network device, where the first message is used to inform the network device that the terminal is currently in an idle state.

[0116] In this way, the terminal that applies the terminal idle state processing method of the embodiment of the present invention executes steps 101 and 102. After completing data transmission in the connected state, it can autonomously switch to the idle state, thereby quickly transitioning from the connected state to the idle state, and inform the network device through the first message that it is currently in the idle state, thereby reducing power consumption and avoiding the loss of business data that may be caused by being out of synchronization with the network state.

[0117] The connection state is the RRC connection state, and the network device may be a base station.

[0118] In addition, in this embodiment, a first event is set, and the occurrence of the first event is used as a condition for directly switching from the connected state to the idle state. For the setting of the first event, the terminal's need to return to the idle state and whether the time from the last successful connection state to the idle state is greater than a specific value will be considered first. Moreover, in order to avoid the terminal's rapid switching in a harsh signal environment, resulting in increased latency and power consumption, whether the received signal or signal-to-noise ratio is greater than a specific value will also be considered. Therefore, optionally, in step 101, the switching of the terminal from the connected state to the idle state includes:

[0119] When a first event occurs, the connection state is switched to the idle state; wherein the first event includes:

[0120] The terminal is required to return to the idle state, the time from the last successful connection state switching to the idle state is greater than the third threshold, and the received signal is greater than or equal to the first threshold; or

[0121] The terminal is required to return to the idle state, the time from the last successful connection state switching to the idle state is greater than the third threshold, and the signal-to-noise ratio SNR is greater than or equal to the second threshold.

[0122] That is, on the one hand, the first event is that the terminal needs to return to the idle state, the time from the last successful connection state to the idle state is greater than the third threshold, and the received signal is greater than or equal to the first threshold; on the other hand, the first event is that the terminal needs to return to the idle state, the time from the last successful connection state to the idle state is greater than the third threshold, and the SNR is greater than or equal to the second threshold. Here, the first threshold, the second threshold, and the third threshold are corresponding parameter settings and can be preset as needed.

[0123] In addition, in this embodiment, optionally, in step 101, switching the terminal from a connected state to an idle state includes:

[0124] Start timing when the data is sent and get the timing duration;

[0125] When the timing duration is equal to the preset duration, switching from the connected state to the idle state is performed.

[0126] In this way, the terminal will switch from the connected state to the idle state after a preset time after the data is sent, thereby avoiding power consumption caused by the terminal needing to re-enter the connected state after the network device sends data within a short period of time after the terminal switches from the connected state to the idle state. The preset time is pre-set according to needs.

[0127] Of course, if the terminal determines that the first event occurs, in addition to immediately switching the connected state to the idle state, the terminal may further perform timing and execute the switching from the connected state to the idle state after the timing duration is equal to the preset duration.

[0128] It should also be known that, in this embodiment, a second event is set, and the occurrence of the second event is used as a switching condition from the non-fast connection state to the idle state. Here, the setting of the second event is relative to the first event, so, optionally, the method further includes:

[0129] When the second event occurs, wait for the network device to send a connection release instruction to switch the connection state to the idle state; wherein the second event includes:

[0130] The received signal is less than the first threshold and the SNR is less than the second threshold; or

[0131] The time from the last successful connection state switching to the idle state is less than a third threshold.

[0132] In this way, in the case where the received signal is less than the first threshold and the SNR is less than the second threshold, or the time from the last successful switch from the connection state to the idle state is less than the third threshold, the connection state will be switched to the idle state after receiving the connection release instruction from the network device, so that the goal of reducing power consumption can be achieved when the second event occurs.

[0133] In this embodiment, optionally, after switching the terminal from the connected state to the idle state, the method further includes:

[0134] If a second message is received and the second message instructs the terminal to wait, the establishment of the radio resource control RRC connection is abandoned; wherein the second message is an RRC connection rejection message.

[0135] Here, the second message is used to instruct the terminal to wait, and may be an RRC connection rejection message (RRCConnection Reject message). After receiving the second message, the terminal can learn that the network is congested by receiving the second message, and thus abandons the RRC connection establishment.

[0136] The RRC Connection Reject message includes: wait time (wait time) or extended wait time (Extended Wait Time) information.

[0137] Generally speaking, after receiving the first message, the network device will send an RRC connection release message to the terminal to avoid resource occupation. Correspondingly, optionally, after sending the first message to the network device, it also includes:

[0138] Receive an RRC connection release message sent by the network device.

[0139] In this embodiment, optionally, the first message is a request message for the terminal to initiate an idle location update TAU.

[0140] That is, after the terminal autonomously switches from the connected state to the idle state, it will send an idle state TAU request message (ie, the first message) to synchronously inform the network device that it is currently in the idle state.

[0141] Of course, in addition to being implemented as an idle state TAU request message, the first message can also be other messages, which are not listed here one by one.

[0142] After receiving the idle state TAU request message, the network device forwards it to the core network, and then receives the TAU success message sent by the core network. Therefore, optionally, before receiving the RRC connection release message sent by the network device, it also includes:

[0143] Receive a TAU success message sent by the network device.

[0144] After the TAU is successful, the core network will notify the network device to release the terminal context.

[0145] Next, combine Figure 2 The application of the method of the embodiment of the present invention is described as follows:

[0146] The terminal autonomously switches the connection state to the idle state;

[0147] The terminal sends an idle state TAU request message to the base station without setting an activation flag (Active flag);

[0148] The base station forwards the idle state TAU request message to the core network;

[0149] After receiving the TAU success message sent by the core network, the base station forwards it to the terminal;

[0150] After receiving the terminal context release message sent by the core network, the base station sends an RRC ConnectionReject message to the terminal and returns a terminal context release success message to the core network.

[0151] In summary, after the terminal completes data transmission in the connected state, it can autonomously switch to the idle state, quickly switch from the connected state to the idle state, and inform the network device through the first message that it is currently in the idle state, reducing power consumption while avoiding the loss of service data that may be caused by being out of sync with the network state. Secondly, in the case of poor terminal coverage or current network congestion, corresponding processing can be performed to avoid longer delays caused by idle state location updates.

[0152] like Figure 3 As shown, an embodiment of the present invention provides a terminal idle state processing method, which is applied to a network device, including:

[0153] Step 301, receiving a first message sent by a terminal; wherein the first message is used to inform the network device that the terminal is currently in an idle state.

[0154] Since the first message is sent after the terminal autonomously switches the connection state to the idle state, the network device can receive the first message after the terminal completes the autonomous switching to know that it is currently in the idle state, thereby reducing power consumption and avoiding possible business data loss due to the lack of synchronization between the terminal and the network state.

[0155] Optionally, the first message is a request message for the terminal to initiate an idle state TAU.

[0156] Optionally, after the receiving terminal sends the first message, the method further includes:

[0157] Forwarding the idle state TAU request message to a core network device;

[0158] Receive a TAU success message sent by the core network device and forward it to the terminal.

[0159] Optionally, after the receiving terminal sends the first message, the method further includes:

[0161] Optionally, after the receiving terminal sends the first message, the method further includes:

[0173] Optionally, the device further comprises:

[0174] The second processing module is used for switching the connection state to the idle state after waiting for the network device to issue a connection release instruction when a second event occurs; wherein the second event includes:

[0176] The time from the last successful connection state switching to the idle state is less than a third threshold.

[0177] Optionally, the device further comprises:

[0215] Receive an RRC connection release message sent by the network device.

[0216] Optionally, the transceiver is further used for:

[0217] Receive a TAU success message sent by the network device.

[0218] The terminal of this embodiment can autonomously switch to the idle state after completing data transmission in the connected state, thereby quickly transitioning from the connected state to the idle state, and inform the network device through the first message that it is currently in the idle state, thereby reducing power consumption and avoiding the loss of business data that may be caused by being out of sync with the network state.

[0219] like Figure 7 As shown, an embodiment of the present invention provides a network device 700, including: a transceiver 710;

[0220] The transceiver is used to receive a first message sent by a terminal; wherein the first message is used to inform the network device that the terminal is currently in an idle state.

[0221] Optionally, the first message is a request message for the terminal to initiate an idle state TAU.

[0222] Optionally, the transceiver is further used for:

[0223] Forwarding the idle state TAU request message to a core network device;

[0232] Among them, Figure 8 In the embodiment of the present invention, the bus architecture may include any number of interconnected buses and bridges, specifically linking various circuits of one or more processors represented by processor 800 and memory represented by memory 820. The bus architecture may also link various other circuits such as peripherals, voltage regulators, and power management circuits, which are well known in the art and are not further described herein.
