It should be understood that the technical solution of the embodiments of the present application may be applied to an LTE (4G) system, an NR (5G) system, or other wireless communication systems (including various future communication systems). Referring to fig. 1, a network architecture diagram of a communication system is shown. As shown in fig. 1, the network architecture may include a network device 101 and a terminal device 102, and a communication connection is established between the network device 101 and the terminal device 102. Optionally, the terminal device may establish a communication connection with the network device through a 5G mobile communication technology, and a communication connection manner of the terminal device and the network device is not specifically limited in this embodiment of the application.

In some embodiments, network device 101 is a device that provides wireless communication capabilities for terminal devices, including but not limited to: an evolved Node B (eNB or e-NodeB) in an LTE system, an NR system, or an LAA-LTE system, a macro Base Station, a micro Base Station (also referred to as a "small Base Station"), a pico Base Station, a Base Transceiver Station (BTS), a Base Band Unit (BBU), an Access Point (AP), a Transmission Point (TP), a new generation Base Station (new generation Node B), or the like.

The terminal device 102 may be referred to as a UE. The Terminal device may be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) Station, a Personal Digital Assistant (PDA), or the like, and may also be a smart phone, a tablet computer, a palm computer, a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), or the like, and the Terminal device may communicate with one or more Network devices through a Radio Access Network (RAN). The terminal equipment may be, for example, a mobile telephone (or so-called "cellular" telephone) or a computer with terminal equipment, etc., and may also be, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device that exchanges voice and/or data with the radio access network. The terminal device may also be a handheld device with a wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a network evolving in the future, and the like, and the implementation of the present application is not limited.

In 5G networks, power consumption is a major factor that plagues terminal devices because of limited battery capacity. For this reason, various methods have been proposed by chip providers, cell phone providers, and the like to save power. The RRC of the terminal device in the 5G network has three states, namely, a connected state, an inactive state, and an idle state. Table 1 shows an example of measured power consumption data for two mainstream terminal devices at the same voltage and the same time. It is noted that the measured power consumption of table 1 is measured in measured current (in milliamps (mA)).

TABLE 1

As shown in table 1, the power consumption of the terminal device a in the connected state is 219.29mA, the power consumption of the inactive state is 10.05mA, and the power consumption of the idle state is 9.93mA, that is, the power consumption of the terminal device a in the idle state is much lower than the power consumption of the connected state; the power consumption of the terminal device B in the connected state is 133.2mA, the power consumption of the terminal device B in the inactive state is 10.91mA, and the power consumption of the terminal device B in the idle state is 10.73mA, i.e., the power consumption of the terminal device B in the idle state is much lower than the power consumption of the terminal device B in the connected state. It can be seen that for RRC of the terminal device, the power consumption in the idle state is much lower than the power consumption in the connected state.

Therefore, when there is no service, the terminal device quickly enters an idle state, which is a more ideal power saving mode. Generally, whether the terminal device enters an Idle State or not is completely controlled by the network device. Fig. 2 is a schematic flowchart illustrating a method for controlling a terminal device to enter an idle state by a network device. As shown in fig. 2, the handover procedure may include:

s201: there is no data transmission both upstream and downstream.

S202: the network device configured idle timer times out.

S203: the network device sends an RRC release message to the terminal device.

S204: the terminal equipment enters an idle state.

It should be noted that, if there is no service between the terminal device and the network device, that is, there is no data transmission in both uplink and downlink, whether the terminal device enters the idle state at this time depends on the network configuration. Specifically, the network device may determine whether an idle timer (Inactive timer) configured in the network device is overtime; if the idle timer is overtime, the network device may send an RRC release message to the terminal device, so that the terminal device enters an idle state after receiving the RRC release message. That is, when there is no data transmission in both uplink and downlink of the terminal device, the terminal device still needs to wait for the network device to send the RRC release message before switching to the idle state.

Therefore, the terminal equipment cannot enter an idle state as soon as possible according to the self requirement, and the reduction of the power consumption of the terminal equipment is limited. Due to factors such as the configuration of the network device and the manufacturer of the network device, the terminal device still cannot enter the idle state quickly when there is no service between the terminal device and the network device.

In order to enable the terminal device to enter the idle state as soon as possible, in some technologies, the terminal device may actively turn off the 5G network and return to the 4G network to enter the 4G RRC idle state, so as to achieve the purpose of saving power. However, if the terminal device enters the 4G RRC idle state, the terminal device cannot use the 5G connection quickly when the terminal device needs the 5G network, and cannot enjoy the 5G ultra-high transmission rate. In addition, in long term, the 5G network must replace the 4G network, rather than supplement the 4G network.

Therefore, switching off the 5G network is only a temporary solution, and optimization within the 5G RAT is a long-term consideration. In other words, how to enable the terminal device to efficiently use the 5G network while saving power is a problem to be solved.

In view of this, an embodiment of the present application provides a power consumption control method, which sends a registration request message to a network device when a state of a terminal device meets an idle state switching condition; wherein, the registration request message is used for instructing the network equipment to send a radio resource control RRC release message; and after receiving the RRC release message sent by the network equipment, controlling the terminal equipment to enter a 5G idle state so as to reduce the power consumption of the terminal equipment. Therefore, the technical scheme of the application can enable the terminal equipment to be still in the 5G network after entering the 5G idle state, so that the terminal equipment can rapidly use the 5G network when having communication requirements, and the transmission rate is high; and the terminal equipment can enter a 5G idle state as soon as possible according to the state of the terminal equipment, the power consumption can be effectively reduced, and the purpose of saving electric quantity is achieved.

Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

In an embodiment of the present application, referring to fig. 3, an interaction flow diagram of a method for controlling power consumption between a terminal device and a network device according to an embodiment of the present application is shown. As shown in fig. 3, the method may include:

s301: and when the state of the terminal equipment meets the idle state switching condition, the terminal equipment sends a registration request message to the network equipment.

It should be noted that the embodiments of the present application are applied to a communication system including a terminal device and a network device. In the communication system, the terminal device and the network device may perform information interaction, for example, the terminal device sends a Registration Request message (Registration Request) to the network device.

It should be further noted that, in the 5G communication protocol, the registration request message carries a field indicating a registration type, so that the registration and update functions can be implemented by setting different registration types (registration types). The correspondence between the registration type and the function is shown in table 2.

TABLE 2

As can be seen from table 2, if the registration request message is used to implement the initial registration function, the registration type is set to "001"; if the registration request message is used for realizing the mobile registration updating function, the registration type is set to be 010; if the registration request message is used for realizing a regular registration updating function, the registration type is set to be 011; if the registration request message is used to implement the emergency registration function, the registration type is set to "100"; if the registration request message is used to implement other reservation functions, the registration type is set to "111".

In this embodiment of the present application, the terminal device may send a registration request message to the network device, where the registration type of the registration request message is set to "010".

Further, the registration request message may include a Follow-on parameter. Wherein, according to the specification of the 5G communication protocol, the following definition of Follow-on parameter is shown in Table 3.

TABLE 3

As can be seen from table 3, if the Follow-on parameter is 0, it indicates that no Follow-on request is pending by the terminal device; if the Follow-on parameter is 1, it indicates that a Follow-on request is pending by the terminal device.

When the terminal device does not have a Follow-on request pending, that is, the terminal device does not have a service request, at this time, the terminal device notifies the network device to send an RRC release message through "Follow-on ═ 0" carried in the registration request message; when the terminal device has a Follow-on request pending, that is, the terminal device has a service request, at this time, the terminal device notifies the network device to reserve the RRC connection through "Follow-on ═ 1" carried in the registration request message.

In other words, the terminal device sends a registration request message to the network device, and may notify the network device whether to send an RRC release message according to a Follow-on parameter carried in the registration request message.

S302: the network device sends an RRC release message to the terminal device.

It should be noted that, after receiving a registration request message sent by a terminal device, a network device may set a Follow-on parameter carried in the registration request message to 0 when the terminal device has no service request, and after receiving the registration request message carrying "Follow-on" 0 ", the network device sends an RRC release message, where the registration request message at this time is used to instruct the network device to send the RRC release message; when the terminal device has a service request, the Follow-on parameter at this time may be set to 1, and after receiving the registration request message carrying "Follow-on ═ 1", the network device will not send an RRC release message, but wait for the terminal device to initiate the service request, in this case, the network device may control whether to send the RRC release message to the terminal device according to the related art shown in fig. 2, according to whether the configured idle timer is overtime.

Based on the specification of the 5G communication protocol, in the embodiment of the present application, a Registration Request may be multiplexed to instruct the network device to send an RRC release message, where a Follow-on parameter in the Registration Request may be set to 0.

S303: and after receiving the RRC release message, the terminal equipment is controlled to enter a 5G idle state.

It should be noted that, when the network device sends an RRC release message to the terminal device, the network device may release the RRC connection; therefore, after the terminal equipment receives the RRC release message, the terminal equipment can be controlled to enter a 5G idle state, and the power consumption of the terminal equipment can be reduced.

It should be noted that as 5G technologies and network deployments mature, power saving schemes in 5G RATs become mainstream. In order to achieve the purpose of saving power of the terminal device in the 5G network, the embodiment of the application may design a power consumption control scheme based on a 5G communication protocol flow according to the requirement of the terminal device itself.

In some embodiments, whether the terminal device switches to the 5G idle state is determined by detecting whether the state of the terminal device meets an idle state switching condition. Herein, the idle state switching condition may be understood as a power saving condition, wherein at least one of the following items may be included:

the electric quantity of the terminal equipment is lower than an electric quantity threshold value;

the terminal device is in a power saving mode.

In this embodiment of the application, the idle state switching condition or the power saving condition may be at least one of that the electric quantity of the terminal device is lower than an electric quantity threshold and that the terminal device is in the power saving mode, or may even be at least one of that the electric quantity is lower than the electric quantity threshold, that the terminal device is in the power saving mode, and other power saving conditions. Here, the other power saving condition may be, for example, a power saving algorithm according to a modem (modem), cooperation of an Application Processor (AP) and a Baseband Processor (BP), and the like, and the embodiment of the present Application is not particularly limited.

It should be noted that, the power of the terminal device is lower than the power threshold, that is, the terminal device is in a low power state. The electric quantity represents the amount of electric charge carried by the object. Generally, the amount of charge is called the coulomb (symbol C), represented by the symbol Q. Since coulomb is a large unit, the amount of electricity is usually expressed in terms of percentage of electricity, which is the ratio between the amount of actual remaining charge and the total amount of charge carried by the object. The electric quantity in the embodiment of the application is the electric quantity percentage. In addition, the threshold value of the electric quantity here is a ratio between a preset quantity of electric charges, which is a preset threshold value for measuring a low electric quantity state, and the total quantity of electric charges carried by the object. In a specific example, the charge amount threshold may be set to 10%, but is not particularly limited.

It should also be noted that the terminal device is in a power saving mode, and in a specific example, the terminal device is in a sleep (Doze) mode. For the Doze mode, the Doze mode is similar to deep sleep, belongs to the power saving mode of the android system, and is not applied to communication optimization. The Doze mode is a state similar to a Doze mode, in which power consumption is reduced by suspending Central Processing Units (CPUs) in the background of the application and network activities. If the fact that the user does not use the terminal equipment within a continuous period of time is detected, CPU and network activities of an application program background in the terminal equipment are delayed, and therefore the purpose of reducing electricity consumption is achieved. It should be noted that the process is only delayed and not killed.

In one possible example, when the idle state switching condition is that "the power of the terminal device is lower than the power threshold", if the power of the terminal device is lower than the power threshold, it may be determined that the state of the terminal device meets the idle state switching condition; if the power of the terminal device is not lower than the power threshold, it can be determined that the state of the terminal device does not conform to the idle state switching condition.

In another possible example, when the idle state switching condition is "the terminal device is in the power saving mode", if the terminal device is in the power saving mode, it may be determined that the state of the terminal device meets the idle state switching condition; if the terminal device is in the non-power saving mode, it may be determined that the state of the terminal device does not comply with the idle state switching condition.

In yet another possible example, when the idle state switching condition is "the power amount of the terminal device is lower than the power amount threshold or the terminal device is in the power saving mode", if the power amount of the terminal device is lower than the power amount threshold or the terminal device is in the power saving mode, it may be determined that the state of the terminal device meets the idle state switching condition; if the electric quantity of the terminal equipment is not lower than the electric quantity threshold value and the terminal equipment is in the non-power-saving mode, the state of the terminal equipment can be determined not to accord with the idle state switching condition.

In yet another possible example, when the idle state switching condition is that "the electric quantity of the terminal device is lower than the electric quantity threshold, or the terminal device is in the power saving mode, or other power saving conditions", if the electric quantity of the terminal device is lower than the electric quantity threshold, or the terminal device is in the power saving mode, or the terminal device meets other power saving conditions, it may be determined that the state of the terminal device meets the idle state switching condition; if the electric quantity of the terminal equipment is not lower than the electric quantity threshold value, the terminal equipment is in a non-power-saving mode, and the terminal equipment does not meet other power-saving conditions, the state of the terminal equipment can be determined not to meet the idle state switching condition.

Further, in some embodiments, the method may further comprise: and if the state of the terminal equipment does not accord with the idle state switching condition, maintaining the state of the terminal equipment.

That is, if the state of the terminal device does not meet the idle state switching condition, the terminal device may not perform the processing, that is, maintain the current state of the terminal device, and even continue to perform the step of determining whether the state of the terminal device meets the idle state switching condition.

Thus, after determining that the state of the terminal device meets the idle state switching condition, the terminal device may send a registration request message to the network device to establish a registration procedure (which may also be referred to as "REG procedure"); then after receiving the registration request message, if the Follow-on parameter is zero, the network device may send an RRC release message to the terminal device to release the RRC connection; after receiving the RRC release message, the terminal device may be controlled to enter a 5G idle state, so as to reduce power consumption of the terminal device.

For example, assuming that the idle state switching condition is "the power of the terminal device is lower than the power threshold, or the terminal device is in the power saving mode, or other power saving conditions", referring to fig. 4, a detailed flowchart of a power consumption control method provided in an embodiment of the present application is shown. As shown in fig. 4, the detailed flow may include:

s401: and no data transmission exists between the terminal equipment and the network equipment.

S402: and judging whether the terminal equipment receives the RRC release message. If the determination result is no, S403 is executed to determine whether the terminal device is in a low power state. If the judgment result is yes, S408 is executed, and the terminal device enters a 5G idle state.

S403: and judging whether the terminal equipment is in a low power state or not. If the determination result is no, S404 is executed to determine whether the terminal device is in the power saving mode. If the result of the determination is yes, S406 is executed, and the terminal device sends a registration request message with a Follow-on parameter set to "0" to the network device.

S404: and judging whether the terminal equipment is in a power saving mode or not. If the determination result is no, S405 is executed to determine whether the terminal device satisfies other power saving conditions. If the result of the determination is yes, S406 is executed, and the terminal device sends a registration request message with a Follow-on parameter set to "0" to the network device.

S405: and judging whether the terminal equipment meets other power saving conditions. If the determination result is no, S402 is executed to determine whether the terminal device receives the RRC release message. If the result of the determination is yes, S406 is executed, and the terminal device sends a registration request message with a Follow-on parameter set to "0" to the network device.

S406: the terminal equipment sends a registration request message with a Follow-on parameter set to be 0 to the network equipment.

S407: the network device sends an RRC release message to the terminal device.

S408: and the terminal equipment enters a 5G idle state.

In this embodiment of the present application, the three determination steps S403, S404, and S405 may constitute a self-defined decision algorithm module of the terminal device. In the self-defined decision algorithm module, as long as one of the three decision steps of S403, S404 and S405 is yes, the self-defined decision algorithm of the terminal device may be ended, and at this time, S406 is executed, that is, the terminal device sends a registration request message with a Follow-on parameter set of "0" to the network device; then, after receiving the registration request message, the network device sends an RRC release message to the terminal device, so that the terminal device enters a 5G idle state.

That is to say, in the embodiment of the present application, the REG procedure conforming to the 3GPP standard protocol may be triggered through the user-defined decision algorithm of the terminal device, and the 5G network is affected, so as to achieve the purpose of autonomously entering the 5G idle state according to the self-requirement.

For convenience of description, in the customized decision algorithm module, the low power state and the power saving mode of the terminal device may be taken as an example, and more decision conditions may be added in the practical application, which is expressed as "other power saving conditions".

With reference to fig. 4, the specific process is as follows:

Step1：

no data transmission exists between the terminal device and the network device, that is, no data transmission exists in uplink and downlink, at this time, the network device waits for the timeout of the configured idle timer (Inactive timer), and then sends an RRC Release Message (RRC Release Message) to the terminal device, so that the terminal device enters an idle state.

Step2：

If the terminal device receives the RRC release message, the terminal device can jump to Step6, so that the terminal device enters an idle state;

otherwise, if the terminal device does not receive the RRC release message, Step3, i.e. the custom decision algorithm module is executed.

Step3：

i) Judging whether the terminal equipment is in a low-power state or not

If the terminal equipment is in a low-power state, jumping to Step 4;

otherwise, entering the next decision condition, where the condition is power saving mode.

ii) determining whether the terminal device is in a power saving mode

If the terminal equipment is in the power saving mode, jumping to Step 4;

otherwise, entering the next condition judgment, wherein the condition is other power saving conditions (the subsequent process can be expanded according to the actual situation).

iii) determining whether the terminal device satisfies other power saving conditions

If the terminal equipment meets other power saving conditions, jumping to Step 4;

otherwise, Step2 and Step3 are re-executed.

Step 4: and triggering the REG flow with the registration type of '010' and the Follow-on request of '0', namely, the terminal equipment sends a registration request message with the Follow-on parameter set to '0' to the network equipment.

Wherein Follow-on is a parameter in the registration request, and according to the specification of the 5G standard protocol, the UE sends an REG request message with Follow-on parameter set to "0" and may instruct the network device to send an RRC release message, that is, the terminal device and the network device enter an RRC idle state. Causing the network device to release the RRC connection.

Step 5: according to the 5G standard protocol, when the network device receives the REG request message carrying the follow-on request of "0", the network device issues an RRC release message to release the resources.

Step 6: the terminal equipment enters an idle state.

Besides, for the RRC of the terminal device, the RRC includes three states, namely, a connected state, an inactive state, and an idle state. If the power consumption in the inactive state or the idle state is much lower than the power consumption in the connected state, before Step4, it may be further performed to determine whether the terminal device is in the connected state.

If the terminal device is in a connected state, then Step4 is entered, that is, the terminal device sends a registration request message with Follow-on parameter set to "0" to the network device, so that the terminal device quickly enters an idle state to reduce power consumption; otherwise (the terminal device is in an inactive state or an idle state), the procedure may be ended.

It should be noted that the technical solution of the embodiment of the present application may be applied to an NR (5G) system, so that the terminal device enters a 5G idle state; the method can also be applied to an LTE (4G) system so as to enable the terminal equipment to enter a 4G idle state. In addition, for other power saving conditions, the technical solution of the embodiment of the present application may further add more decision conditions according to the requirements of a modem power saving algorithm, cooperation of an AP and a BP, and the like, so as to achieve refined power saving, which is not limited herein.

Further, it should be noted that, in the case that there is no service between the terminal device and the network device, the terminal device will determine whether to switch to the 5G idle state. Therefore, in some embodiments, before sending the registration request message to the network device when the state of the terminal device meets the idle-state handover condition, the method may further include: and determining that no data is transmitted between the terminal equipment and the network equipment.

That is, if there is traffic (uplink and downlink data transmission) between the terminal device and the network device, the terminal device does not release the RRC connection, i.e., does not switch to the 5G idle state. If there is no service (no uplink and downlink data transmission) between the terminal device and the network device, the terminal device may autonomously trigger the REG procedure according to its own state at this time, so as to switch to the 5G idle state.

In some embodiments, an idle timer is configured in the network device, and the method may further include: starting an idle timer; and sending an RRC release message to the terminal equipment under the condition that the timing duration of the idle timer exceeds the preset duration.

Thus, if the configured idle timer in the network device expires, the network device will be prompted to actively send an RRC release message. Therefore, for the terminal device, after determining that there is no data transmission between the terminal device and the network device, the method may further include:

judging whether an RRC release message sent by the network equipment is received;

and if the RRC release message sent by the network equipment is not received, sending a registration request message to the network equipment.

In the embodiment of the present application, there are at least two cases that may cause the network device to send the RRC release message. One possible case is that the network device configured idle timer expires, causing the network device to send an RRC release message, and another possible case is that the terminal device may autonomously trigger the REG procedure according to its own status to cause the network device to send an RRC release message.

In the embodiment of the present application, for a terminal device, the terminal device needs to first determine whether an RRC release message sent by a network device is received, and if the RRC release message sent by the network device is not received, it needs to also determine whether a state of the terminal device meets an idle state switching condition; when the state of the terminal device meets the idle state switching condition, the terminal device may trigger the REG procedure and send a registration request message to the network device. In other words, if there is no data transmission between the terminal device and the network device and the idle timer configured by the network device has not timed out yet, at this time, the terminal device may autonomously trigger the REG procedure according to its own state to prompt the network device to send the RRC release message, so that the terminal device quickly enters the 5G idle state.

That is to say, the technical solution of the embodiment of the present application can implement that the terminal device can be in an idle state as much as possible according to the service requirement of the terminal device by using a 3GPP protocol standard flow, thereby achieving the purposes of saving electric quantity and prolonging standby time. Specifically, the terminal device can autonomously control the trigger protocol flow according to the needs of the self condition (electric quantity, mode, service, etc.) to influence the network, so that the terminal device enters a 5G idle state as soon as possible; therefore, the 5G network can be used rapidly, and the 5G ultrahigh transmission rate can be enjoyed; but also can save the electric quantity as much as possible.

In short, this embodiment provides a power consumption control method, which sends a registration request message to a network device when a state of a terminal device meets an idle state switching condition; the registration request message is used for indicating the network equipment to send an RRC release message; the network equipment sends RRC release information to the terminal equipment according to the registration request information; and after the terminal equipment receives the RRC release message, controlling the terminal equipment to enter a 5G idle state so as to reduce the power consumption of the terminal equipment. Therefore, after entering the 5G idle state, the technical scheme of the application is still in the 5G network, can quickly use the 5G network for connection when communication needs exist, is finely controlled, does not need to completely close the 5G network, and has high transmission rate; and the terminal equipment can enter a 5G idle state as soon as possible according to the state of the terminal equipment, the power consumption can be effectively reduced, and the purpose of saving electric quantity is achieved.
