Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a wake-up method and a communication device. Background Art

[0002] Currently, with the continuous evolution of technology, terminal equipment can support communication with multiple communication systems. For example, the terminal equipment can communicate with some or all of the multiple communication systems at the same time.

[0003] When a terminal device communicates with multiple communication systems, the communication modules corresponding to the multiple communication systems are all in working condition. Even if no business occurs between the terminal device and one of the communication systems within a certain time period, that is, no data corresponding to the communication system is sent or received, the communication modules corresponding to the multiple communication systems within the time period are still in working condition, that is, working at the same time, which results in a waste of power consumption of the terminal device. Summary of the invention

[0004] The embodiments of the present application provide a wake-up method and a communication device, which can reduce the power consumption of terminal equipment.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, a wake-up method is provided, which is applied to a first communication node, wherein the first communication node includes at least two communication modules, the at least two communication modules correspond to at least two communication systems, and the communication modules are used to support the first communication node and the network element communication in the communication system corresponding to the communication module, and the method includes: the first communication node detects whether there is business between the first communication system and the first communication system. In response to no business occurring between the first communication node and the first communication system, the first communication node is triggered to be in a first state, and the first state includes: shutting down the first communication module corresponding to the first communication system in the at least two communication modules, and keeping the second communication module in the at least two communication modules in a first working state. The second communication module supports receiving a wake-up signal from the first communication system. The second communication module is a communication module whose power consumption is lower than a preset power consumption threshold among the at least two communication modules.

[0007] By adopting the above technical solution, when the first communication system has no business, the first communication node only needs the second communication module with low power consumption to be in working state, and other communication modules are turned off, which can save the power consumption of the terminal. In addition, the second communication module supports receiving the wake-up signal of the first communication system, and can start the first communication module based on the wake-up signal without affecting the business processing of the first communication module.

[0008] In a possible implementation of the first aspect, the first communication system may be a cellular communication system. The second communication module corresponds to the second communication system, and the second communication system may be a Wi-Fi communication system. Then, the first communication module is a cellular communication module, and the second communication module is a Wi-Fi communication module. Among them, WUR may be set in the Wi-Fi communication module to achieve low-power standby. Thus, the Wi-Fi communication module is a communication module whose power consumption is lower than a preset power consumption threshold among at least two communication modules.

[0009] In a possible implementation of the first aspect, the method further includes: when there is a service to be sent to the first communication node in the first communication system, the first communication node can receive a wake-up signal through the second communication module, and the wake-up signal is used to wake up the first communication module to receive the service from the first communication system. Then, the first communication node can start the first communication module based on the received wake-up signal. Thus, after starting the first communication module, the first communication node communicates with the first communication system to complete the current service.

[0010] In a possible implementation of the first aspect, before triggering the first communication node to be in the first state, it also includes: if it is detected that a first service exists between the first communication node and the second communication system corresponding to the second communication module, data of the first service is transmitted through the second communication module; and / or, if it is detected that a second service exists between the first communication node and the first communication system, data of the second service is transmitted through the first communication module.

[0011] In a possible implementation of the first aspect, the method further includes: the first communication node reports capability information, wherein the capability information is used to indicate whether the first communication node has the capability to receive a wake-up signal through a second communication module. Thus, if the capability information reported by the first communication node indicates that the first communication node has the capability to receive a wake-up signal through a second communication module. Then, after the first communication node enters the first state, the wake-up signal is received through the second communication module.

[0012] In a possible implementation of the first aspect, triggering the first communication node to be in the first state includes: the first communication node receives a first request message; wherein the first request message is used to request to disconnect the communication between the first communication node and the network element in the first communication system. The first communication node can switch the first communication node to the first state in response to the first request message. Thus, the first communication node disconnects the communication between the first communication node and the network element in the first communication system, which is equivalent to shutting down the first communication module. Then, when there is no business between the first communication node and the first communication system, the power consumption of the first communication node can be saved.

[0013] In a possible implementation of the first aspect, keeping the second communication module of at least two communication modules in the first working state includes: the first communication node turns off the main receiver in the second communication module and turns on the wake-up receiver WUR in the second communication module. Thus, the second communication module can achieve low-power standby based on WUR.

[0014] In a possible implementation of the first aspect, the method further includes: in response to no business occurring between the first communication node and the first communication system, and between the first communication node and the second communication system, triggering the first communication node to be in a second state. The second state includes: turning off the first communication module and keeping the second communication module in a second working state; the power consumption of the second communication module in the second working state is higher than the power consumption in the first working state. Among them, the second working state may refer to a sleep (deep sleep) state, at which time the communication module turns off or reduces the power consumption of most circuit elements, and only retains the necessary circuits for basic maintenance and monitoring functions to extend battery life or reduce overall energy consumption. Among them, the necessary circuits retained are used to receive inquiry messages from the second communication system. Compared with the normal working state of the communication module, the communication module in the second working state can significantly reduce power consumption; compared with the first working state, the communication module in the second working state needs to retain the circuit for receiving the inquiry message from the second communication system, and the power consumption is slightly higher. Then, the first communication node may receive an inquiry message from the second communication system; the inquiry message is used to inquire whether there is any service to be transmitted through the first communication system and / or the second communication system on the first communication node; and the first communication module and / or the second communication module are turned on according to the inquiry message.

[0015] Among them, if there is a service to be transmitted through the first communication system on the first communication node, the first communication node turns on the second communication module, and receives the wake-up signal of the first communication system through the second communication module, and then turns on the first communication module to implement the service transmitted by the first communication system. If there is a service to be transmitted through the second communication system on the first communication node, the first communication node turns on the second communication module to implement the service transmitted by the second communication system.

[0016] In a second aspect, the present application provides a communication device, comprising: a first communication module, a second communication module, a memory and one or more processors; the first communication module, the second communication module, the memory and the processor are coupled; the memory is used to store computer program code, and the computer program code includes computer instructions, and when the computer instructions are executed by the communication device, the communication device executes any one of the methods described in the first aspect above.

[0017] In a third aspect, the present application provides a computer-readable storage medium, in which instructions are stored, and when the computer-readable storage medium is run on a computer, the computer can execute any of the methods described in the first aspect.

[0018] In a fourth aspect, the present application provides a computer program product comprising instructions, which, when executed on a computer, enables the computer to execute any of the methods described in the first aspect.

[0019] It can be understood that the communication device described in the second aspect provided above, the computer-readable storage medium described in the third aspect, and the computer program product described in the fourth aspect are all used to execute the corresponding methods provided above. Therefore, the beneficial effects that can be achieved can refer to the beneficial effects in the corresponding methods provided above, and will not be repeated here.

[0032] The following will describe the technical solutions in the embodiments of the present application 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 this application.

[0033] It should be noted that the following terms "first", "second", etc. are only used for descriptive purposes and should not be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0034] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0035] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0036] With the continuous evolution of technology, the capabilities of terminals are constantly enhanced, and terminals can support communication with multiple communication systems at the same time. For example, multiple communication modules can be set in the terminal, and the multiple communication modules correspond to multiple communication systems. The terminal can communicate with multiple communication systems through these multiple communication modules, that is, it has the ability to work with multiple communication systems. In the case of coexistence of multiple communication modules of the terminal, there will be a situation where multiple communication modules are in working state at the same time, so as to receive information from different communication systems. In the case where multiple communication modules of the terminal are in working state at the same time, there may be no data transmission for a long time, or there may be only information from a certain communication system. Then, when multiple communication modules are in working state at the same time, there will be energy waste, which increases the power consumption (or power consumption) of the terminal.

[0037] In this application, the communication system may be referred to as a network access system, a wireless system, a communication network, etc. The communication system includes but is not limited to a Wi-Fi (Wireless Fidelity) communication system (or simply a Wi-Fi system), a cellular communication system, an Ultra Wide Band (UWB) communication system, and a Bluetooth communication system. The cellular communication system may include but is not limited to the fourth generation (4G) th generation, 4G) mobile communication system, 5G mobile communication system, or future evolution system.

[0038] In this application, a communication module may refer to a functional module that has the ability to send and receive information and / or data. A communication module may include a receiver and / or a transmitter. For ease of description, a communication module corresponding to a communication system A may be referred to as an A communication module, for example, a communication module corresponding to a cellular communication system may be referred to as a cellular communication module, a communication module corresponding to a Wi-Fi communication system may be referred to as a Wi-Fi communication module, and a communication module corresponding to a Bluetooth communication system may be referred to as a Bluetooth communication module, etc.

[0039] In one example, taking the communication between the terminal and the cellular communication system as an example, in order to reduce the power consumption (or power consumption) of the terminal, a wake-up receiver (WUR) is introduced in the terminal, that is, the cellular communication module corresponding to the cellular communication system in the terminal includes a main receiver and a WUR. The main receiver is mainly used to support the communication between the terminal and the cellular communication system, such as sending and receiving service data, etc. When the terminal is in an idle state or an inactive state, that is, when the terminal has not established a connection with the cellular communication system, the main receiver stops working, and the WUR is in a working state, that is, in an on state. The WUR is used to receive a wake-up signal (WUS). After the WUR receives the wake-up signal, the terminal can wake up the main receiver based on the wake-up signal, re-establish a connection with the cellular communication system, and communicate with the cellular communication system. In this way, the standby power consumption of the terminal can be reduced by introducing the WUR, and the function of waking up the terminal on demand by receiving the wake-up signal through the WUR can be guaranteed.

[0040] In this application, WUR can be referred to as a Low Power- Wake-Up Receiver (Lower Power- Wake-Up Receiver), so WUR can also be recorded as LP-WUR. Specifically, WUR usually runs continuously in a low power mode to monitor wake-up signals from external sources. These wake-up signals usually have a shorter length and lower power consumption requirements than conventional communication signals. Once WUR detects a valid wake-up signal, it decodes the signal to determine whether the main receiver needs to be woken up. If the decoding result indicates that the main receiver needs to be woken up, the WUR sends an internal signal to trigger the wake-up process of the main receiver. After the main receiver is awakened, it will begin to receive and process conventional communication data from external sources. At the same time, WUR may return to low power monitoring mode, waiting for the next wake-up signal to arrive.

[0041] like Figure 1 As shown, Figure 1 The following are two common hardware structures of WUR. Figure 1 As shown in (a), the extremely simple hardware is used, mainly including: narrow-band bandpass filter / resonator, amplifier (optional), detector, low pass filter (LPF), baseband amplifier (BB amp), analog-to-digital converter (ADC) and digital processing part. Among them, the amplifier can be a low noise amplifier (LNA). The detector can be an envelope detector (ED).

[0042] The second hardware structure is as follows Figure 1 As shown in (b), it mainly includes: narrowband bandpass filter / resonator, amplifier (optional), local oscillator and mixing module, bandpass filter, detector, low-pass filter, baseband amplifier, analog-to-digital converter (ADC) and digital processing part. Compared with the first hardware structure, the second hardware structure mainly adds a local oscillator and mixing module, in which the narrowband bandpass filter / resonator at the front end is optional, and the other hardware parts are basically the same. Among them, the phase-locked loop (PLL) / frequency-locked loop (FLL) is used to generate the local oscillator signal. Both of the above hardware structures can be used as long as they can achieve the purpose of low-power reception.

[0043] Among them, WUR can adopt multi-carrier on-off keying (OOK) modulation, which can theoretically achieve uW-level standby power consumption. Specifically, the various functional modules included in WUR and the capabilities of each functional module can refer to the existing technology and will not be described in detail.

[0044] Among them, any communication module in the terminal can add WUR, that is, any communication module can include a main receiver and WUR, which can receive and identify the wake-up signal of the communication system corresponding to the communication module without consuming too much power through the low power consumption characteristics of WUR when the main receiver in the communication module is dormant, thereby reducing the standby power consumption of the terminal. It should be understood that in this application, when there is no business between the terminal and a communication system, the main receiver in the communication module corresponding to the communication system stops working and is in a dormant state or in an OFF state. When business is to occur between the terminal and the communication system (or is called waiting for communication), the main receiver is awakened and switched from the dormant state to the working state (or is called standby state / power-on (ON) state).

[0045] In this embodiment, the Wi-Fi communication module is added to WUR as an example. Figure 2As shown, a system block diagram of adding WUR to the Wi-Fi communication module is shown. WUR is added to the original receiver structure of the Wi-Fi communication module, wherein the original receiver can be called the main receiver, so that a low-power wake-up mechanism based on the 802.11 standard is implemented through WUR. The transmitter can transmit a signal including a data packet, or transmit a signal including a wake-up packet. For example, when a service occurs, the main receiver 201 in the receiver is in a working state, the transmitter sends the data packet of the service to the receiver, and the receiver receives the data packet through the main receiver 201. When it is detected that no business has occurred for a period of time, the main receiver 201 is in standby mode. Before the subsequent transmission of the data packet of the business, the transmitter sends a signal including a wake-up packet (or called a wake-up signal) to the receiver. After the WUR202 in the receiver receives the signal through the antenna, it is amplified by a high-frequency amplifier and demodulated by a demodulator, and finally the wake-up packet is restored from the received signal. Then, an internal signal is sent based on the wake-up packet to wake up / trigger / start the main receiver 201, so as to realize the normal data packet transmission between the receiver and the transmitter. Figure 2 As shown, the main receiver 201 is in the OFF state and the WUR 202 is in the ON state.

[0046] The above solution adopts adding WUR in the communication module to reduce the standby power consumption of the terminal. However, this solution not only requires adding additional devices, but also requires keeping some devices in the communication module in a working state. It is impossible to set the communication module to a sleep state completely, that is, it is impossible to set the communication module to a deep sleep (or deep sleep), which will still increase the standby power consumption (or simply power consumption) of the terminal.

[0047] In order to solve the above problems, an embodiment of the present application proposes a wake-up method, which is applied to a terminal, wherein the terminal includes at least two communication modules in a working state, the at least two communication modules correspond to at least two communication systems, and the communication modules are used to support the communication between the terminal and the network elements in the communication system corresponding to the communication modules. The wake-up method includes: if there is no business between the terminal and the first communication system in the at least two communication systems, the first communication module corresponding to the first communication system is turned off, and the second communication module in the at least two communication modules is kept in a working state (set to a first working state), the second communication module is a communication module in the at least two communication modules whose power consumption is less than a preset threshold, and the second communication module is used to receive a wake-up signal corresponding to the first communication system. As a result, the terminal only needs the communication module with low power consumption to be in a working state, and the other communication modules are all turned off, that is, the other communication modules are in deep dormancy (or deep sleep), which can save the power consumption of the terminal.

[0048] In this embodiment, the terminal can achieve low-power standby by setting a WUR in the receiver circuit of the second communication module and keeping the WUR in the second communication module in a working state to receive a wake-up signal. For ease of understanding, in the subsequent embodiments, the second communication module is a Wi-Fi communication module, the first communication module is a cellular communication module, and the WUR is set in the receiver circuit of the Wi-Fi communication module.

[0049] The wake-up method provided by the present application is described below in conjunction with the accompanying drawings:

[0050] See also Figure 3 , Figure 3 A possible, non-limiting system diagram including multiple communication systems is provided for an embodiment of the present application. Figure 3 As shown, the communication system 1001 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 1001 may also include the Internet 300. The RAN 100 includes at least one RAN node (such as Figure 3 The macro base station 110a and AP110b in the embodiment and at least one terminal (such as Figure 3 It should be understood that the terminal 120a and the terminal 120f are two different terminals, so they are marked with different reference numerals. In other embodiments of the present application, different terminals are marked with different reference numerals to distinguish the expressions. The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices ( Figure 3 The terminal is connected to the RAN node by wireless means. The RAN node is connected to the core network 200 by wireless or wired means. The core network device in the core network 200 and the RAN node in the RAN 100 can be different physical devices, or the same physical device that integrates the core network logical function and the radio access network logical function.

[0051] RAN100 may include 3GPP-related cellular communication systems, such as 4G mobile communication systems, 5G mobile communication systems, or future evolution systems, and may also include Wi-Fi communication systems. In addition, RAN100 may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (cloud radio access network, CRAN), or other communication systems that integrate two or more of the above systems.

[0052] RAN nodes, sometimes also called network equipment, access network equipment, RAN entities or access nodes, etc., constitute part of the communication system to help terminals achieve wireless access. Multiple RAN nodes in the communication system 1001 can be nodes of the same type or nodes of different types.

[0053] In a cellular communication system related to 3GPP, a RAN node may be a base station, an access point (AP), or a transmission reception point (TRP). The base station may include an evolved NodeB (eNodeB), a next generation NodeB (gNB), or a base station in a future mobile communication system. In a Wi-Fi communication system, a RAN node may be an AP or an access node, etc. A RAN node may be a macro base station 110a, a micro base station or an AP110b, a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node may also be a server, a wearable device, a vehicle or an onboard device, etc. For example, the access network device in the V2X technology may be a road side unit (RSU). All or part of the functions of the RAN node in this application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform). A communication module, circuit, or chip for performing corresponding communication functions may also be provided in the RAN node. The RAN node may also be configured with program instructions for performing corresponding communication functions and corresponding program instructions. The RAN node in the present application may also be a logical node, a logical module or software that can implement all or part of the RAN node functions.

[0054] The terminal may be a device or module that supports access to multiple communication systems, such as supporting access to a cellular communication system and a Wi-Fi communication system, and has corresponding communication functions. The terminal may also be referred to as a terminal device, a user equipment (UE), a mobile station, a mobile terminal, etc. The terminal may be widely used in various scenarios, for example, D2D, V2X communication, machine-type communication (MTC), the Internet of Things (IoT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, a transport vehicle with wireless communication function, a communication module, etc. The embodiments of the present application do not limit the device form of the terminal. A communication module, a circuit or a chip that performs the corresponding communication function is usually provided in the terminal. The terminal is also configured with program instructions for performing the corresponding communication function.

[0055] Generally speaking, if the terminal 120a and the terminal 120f connected to the same macro base station 110a need to make a call, the specific steps include: the terminal 120a initiates a call request to the macro base station 110a, the macro base station 110a sends the call request to the core network 200, and the core network 200 determines the terminal device (terminal 120f) called by the terminal 120a according to the call request. Then, the core network 200 sends a call request to the macro base station 110a to which the terminal 120f is connected, and the macro base station 110a sends the call request to the terminal 120f. At this time, communication is established between the terminal 120f and the terminal 120a, and the terminal 120a can make a call with the terminal 120f.

[0056] In the above process, the cellular communication module of the terminal 120a needs to be in working state all the time in order to receive the message sent by the macro base station 110a and realize communication with other devices through the macro base station 110a. However, for the terminal 120a, if there is no service to be sent to the terminal 120a on the macro base station 110a for a long period of time, then the cellular communication module of the terminal 120a is in working state all the time during this period of time, which will cause the power consumption of the terminal 120a to be wasted.

[0057] In order to solve the problem of power consumption waste of terminal 120a, the cellular communication module of terminal 120a does not need to be kept in working state all the time, but the cellular communication module of terminal 120a is turned off to make it in deep sleep, and low power consumption standby is achieved through the Wi-Fi communication module in working state in terminal 120a. Terminal 120a can turn off the cellular communication module when there is no data transmission in the cellular communication system; when there is data transmission in the cellular communication system, the cellular communication module can be awakened by the Wi-Fi communication system in working state controlled by the core network, so that only the Wi-Fi communication module in terminal 120a needs to be kept in working state, saving the power consumption of terminal 120a.

[0058] Later, in Figure 3 In the communication system shown, after receiving the call request to be sent to the terminal 120a, the macro base station 110a to which the terminal 120a is connected sends the call request to the core network 200. After receiving the call request, the core network 200 can wake up the cellular network of the terminal 120a through the Wi-Fi network to realize the call between the two terminals. At this time, the core network 200 sends a wake-up signal to the Internet 300, and the Internet 300 sends a wake-up signal to the AP110b connected to the terminal 120a through the router. Then, the AP110b determines the called terminal device (terminal 120a) according to the wake-up signal, and initiates a wake-up signal to the terminal 120a through the Wi-Fi network.

[0059] The above-mentioned AP110b initiates a wake-up signal to the terminal 120a through the Wi-Fi network. Specifically, AP110b sends a message to the Wi-Fi network, and the Wi-Fi network judges the received message to determine whether the message is a wake-up signal for waking up the cellular baseband signal. If so, the WUR of the Wi-Fi communication module wakes up the main receiver of the cellular communication module after receiving the wake-up signal. Subsequently, the terminal 120a can receive the paging signal sent by the base station through the main receiver of the cellular communication module. At the same time, the Wi-Fi network replies to the AP110b with a confirmation message. After receiving the confirmation message of the reply from the Wi-Fi network, AP110b sends a message to the core network 200 again, which is used to indicate that the Wi-Fi network where the terminal 120a is located confirms that the cellular baseband signal of the terminal 120a needs to be awakened. After receiving the message, the core network 200 determines the target base station (i.e., the macro base station 110a) where the terminal 120a is located, and sends a paging signal to the target base station. At this time, the target base station sends a paging signal to the terminal 120a again.

[0060] The following describes the embodiments of the present application by taking at least two communication systems including a cellular communication system and a Wi-Fi communication system as an example. Figure 4 , Figure 4Schematic diagram of a cellular communication system and a Wi-Fi communication system. In a cellular communication system, a base station can be connected to multiple UEs. In a Wi-Fi communication system, an AP can be connected to multiple UEs. The core network can simultaneously connect to multiple base stations and multiple APs through a gateway interface (S / X interface). Figure 4 As shown in the figure, the core network is connected to n base stations (base station 1-base station n) through gateway interface 1, and the core network is connected to n APs (AP1-APn) through gateway interface 2. Each base station and each AP can be connected to multiple UEs at the same time. Figure 4 As shown, each base station can be connected to UEn at the same time (n=1, 2, 3...), and each AP can also be connected to UEn at the same time. Data can be transmitted between gateway interface 1 and gateway interface 2 through a common gateway protocol.

[0061] It should be noted that in actual scenarios, a UE can only be connected to one gNB and one AP. Only when the switching condition is triggered will the UE connect to another gNB or AP that meets the switching signal quality.

[0062] When the gNB has a telephone service for a certain UE and the AP has a data service for the UE, the gNB and the AP are simultaneously connected to the UE and generate service power consumption with the core network. Specifically, the gNB will perform closed-loop power control based on the channel signals such as the Physical Random Access Channel (PRACH) / Physical Uplink Control Channel (PUCCH) / Quality of Service (QOS) / QSQQ reported by the UE, and the gNB will periodically complete the synchronization of messages such as the Synchronization Signal Block (SSB) / System Information Block (SIB) / Master Information Block (MIB) in a fixed time slot structure, determine the position relationship between the gNB and the UE, signal strength, service data level, etc. through message synchronization, and activate or silence the UE. Specifically, the message synchronization process can refer to the existing technology and will not be repeated.

[0063] At the same time, the AP will also periodically complete message exchange with the UE based on the signal quality report / reference signal received quality (RSRQ) / association request frame (ASSOC req) + association reply frame (ASSOC rsp) and other messages reported by the UE, and determine the UE's location, power level, data throughput requirements, etc. through message exchange. Specifically, the message exchange process can refer to the existing technology and will not be described in detail.

[0064] The base station supports the 3gpp protocol, and the AP supports the 802.11 protocol.

[0065] In order to ensure that data can be correctly and efficiently transmitted between different devices, the Wi-Fi communication system and the cellular communication system are provided with underlying software, high-level protocol stacks, logical channels, transmission channels, and physical channels, etc. Different types of information or messages are transmitted and / or processed through the underlying software, high-level protocol stacks, logical channels, transmission channels, and physical channels to ensure that data can be correctly and efficiently transmitted and / or processed between different devices. It should be understood that since the communication formats supported by the Wi-Fi communication system and the cellular communication system are different, the formats of information or messages processed and / or transmitted by the underlying software, high-level protocol stacks, logical channels, transmission channels, and physical channels included in the Wi-Fi communication system and the cellular communication system may be different.

[0066] See also Figure 5 , Figure 5 The following figure shows the underlying software, high-level protocol stack, logical channels, transport channels, and physical channels. Figure 5 As shown in FIG. 1 , in the Wi-Fi communication system and the cellular communication system, system information, such as MIB / SIB, is generated by the underlying software and the high-level protocol stack, and is transmitted through the corresponding logical channels, transmission channels and physical channels. Among them, the underlying software may include but is not limited to operating systems, database management systems, compilers, etc. The high-level protocol stack refers to a set of network communication protocols arranged in a strict order, usually composed of multiple layers, each layer is responsible for different functions. The design of the protocol stack follows standards such as the open system interconnection (OSI) model or the TCP / IP model proposed by the Internet Engineering Task Force (IETF). In the communication system, the high-level protocol stack is responsible for the encapsulation, transmission and parsing of data to ensure that data can be transmitted correctly and efficiently between different devices. The hierarchical structure of the protocol stack makes network communication more orderly and reliable, and provides interoperability and scalability.

[0067] Logical channels are channels that transmit different types of information on physical channels. They are services provided by the MAC sublayer to the upper layer. They indicate what the content is and can be divided into two categories: control channels and traffic channels. Control channels are used to transmit control plane information. For example, logical channels include paging control channels (PCCH), broadcast control channels (BCCH), and common control channels (CCCH).

[0068] The transmission channel focuses on how data is transmitted, and it defines the mode and characteristics of data transmission in the air interface. By forming a transmission block, different types of transmission channels correspond to the baseband processing methods of different signals on the air interface, such as modulation and coding methods, interleaving methods, redundancy check methods, spatial multiplexing methods, etc. Transmission channels can be divided into two categories: shared channels and dedicated channels. Shared channels allow multiple users to occupy channel resources together, while dedicated channels are exclusively occupied by a certain user, such as downlink shared service channels and uplink service shared channels. Specifically, transmission channels can include paging channels (Paging Channel, PCH), dedicated channels (Dedicated Channel, DCH), downlink shared channels (Downlink Shared Channel, DL-SCH), uplink shared channels (Uplink Shared Channel, UL-SCH), etc.

[0069] The physical channel is the physical channel for information transmission, corresponding to the actual radio frequency resources, and is the infrastructure for information transmission. It carries digital or analog signals and establishes a physical connection path between the two communicating parties. The physical channel can be a wired medium such as a telephone line, optical fiber, coaxial cable, or a wireless medium such as radio waves and microwaves. Specifically, the physical channel can include the Physical Broadcast Channel (PBCH), the Physical Downlink Shared Channel (PDSCH), the Physical Uplink Shared Channel (PUSCH), etc.

[0070] As can be seen above, the underlying software, high-level protocol stack, logical channel, transport channel and physical channel play different roles in the communication system. They work together to ensure that the UE accesses the communication system and, after accessing the communication system, performs signaling interaction with the devices in the communication system (such as base stations) to ensure normal data transmission.

[0071] The following takes the above-mentioned cellular communication system as a 5G communication system as an example to introduce the 5G signaling process in the 5G communication system.

[0072] like Figure 6 As shown in the figure, the wireless access process from user equipment (UE) to base station (gNB) and then to 5G core network (5GC) is shown. The key steps of a 5G signaling process include the following steps 1 to 6:

[0073] Step 1: Radio Resource Control (RRC) is established.

[0074] Among them, RRC establishment mainly includes random access (step 1), RRC connection request (step 2), RRC connection establishment (step 3) and RRC connection establishment completion (step 4). Specifically, random access (step 1) includes: after the UE selects the Public Land Mobile Network (PLMN), scans the frequency point and selects the cell, it initiates random access to the selected gNB cell. RRC connection request (step 2) includes: the UE sends an RRC connection request to the gNB, carrying the UE identifier and the establishment cause value (such as mobile originated data service (Mobile Originating Data, referred to as MO-Data), mobile originated signaling (Mobile Originating signalling, referred to as MO-signalling), etc.). RRC connection establishment (step 3) includes: the gNB replies to the UE with RRC connection establishment, carrying the initial uplink and downlink bandwidth part (Bandwidth Part, BWP), channel state information (CSI), T310 / N310 / N311 timer, etc. The RRC connection establishment completion (step 4) includes: the UE replies to the gNB that the establishment is completed, carrying the selected PLMN identity (selectedPLMN-Identity), the registered (registered) AMF, the slice selection assistance information list (Slice Selection AssistanceInformation List, referred to as snssai-list) and the non-access stratum (NAS) message.

[0075] Step 2: Authentication.

[0076] Authentication mainly includes initial UE information (step 5), NGMM authentication request (step 6), and NGMM authentication response (step 7).

[0077] Among them, step 5 includes gNB sending initial context information to the core network AMF. Then, the core network sends a context establishment request to the UE, which mainly includes the UE's aggregate maximum bit rate (Aggregate Maximum Bit Rate, AMBR), mobility restriction list (mobility-RestrictionList), UE security capabilities (UE-securityCapabilities), core network assistance information (for inactive state) (coreNetworkAssistanceInformationForInactive) and other information elements. Figure 6 As shown in the figure, the core network first sends the downlink non-access stratum transmission (DownLink‌‌ Non-Access Stratum Transport, referred to as DL NAS TRANSP) of the NG Application Protocol (NG Application Protocol, AP) to the gNB, and the gNB then transmits the RRC downlink information to the UE.

[0078] like Figure 6 As shown, the UE sending an NGMM authentication response to the core network may include the UE first transmitting RRC uplink (UpLink, UL) information to the gNB, and then the gNB sending an uplink NAS transmission performed by NGAP to the core network, thereby implementing the NGMM authentication response sent by the UE.

[0079] Step 3: Encryption.

[0080] Encryption mainly includes NGMM Secu Command (CMD) (step 8) and NGMM Secu Complete (CMP) (step 9).

[0081] like Figure 6 As shown in the figure, the process of the core network sending NGMM security commands to the UE is achieved by first sending NGAP to the gNB for downlink NAS transmission, and then the gNB transmits RRC downlink information to the UE. The process of the UE sending NGMMSecu to the core network is completed by first transmitting RRC uplink information to the gNB, and then the gNB sends NGAP to the core network for uplink NAS transmission.

[0082] Step 4: Query UE (user equipment) capability information.

[0083] The UE (user equipment) capability information query mainly includes NGAP initial context setup request (INIT CONTEXTSetup Req) (step 10), RRC UE capability (Capabilities, CAP) inquiry (ENQUIRY) (step 11), RRC UE CAP information (INFO) (step 12) and NGAP UE capability information indication (CAP INFO IND) (step 13).

[0084] Among them, step 11 includes the gNB sending an indication to the UE to query the UE capability information, and the indication includes the frequency band information (freqBandinformation) information element. Step 12 includes the UE replying the UE capability information to the gNB, including the capabilities supported by PDCP / RLC / MAC / PHY and RF. Step 13 includes the gNB transparently transmitting the UE capability information to the core network.

[0085] Step 5. Enable security (Secu) mode.

[0086] The activation of the security mode mainly includes RRC Secu Mode CMD (step 14) and RRC Secu Mode CMP (step 15).

[0087] After the security mode is set up, perform RRC connection configuration (CONN CFG) (step 16), RRC connection configuration completion (CONN CFG CMP) (step 17), and NGAP initial context setup response (NGAP INIT CONTEXT Setup Rsp) (step 18).

[0088] Among them, step 16 includes the gNB sending an RRC reconfiguration message to the UE to activate BWP1. Step 17 includes the UE replying to the gNB that the RRC reconfiguration is completed. Step 18 includes the gNB replying to the core network that the UE uplink and downlink establishment is completed.

[0089] Step 6: Signaling Radio Bearer (SRB) 2 and Data Radio Bearer (DRB) are established.

[0090] The establishment of SRB2 and DRB mainly includes Protocol Data Unit (PDU) Session Setup Req (step 19), RRC CONN CFG (step 20), RRC CONN CFG CMP (step 21) and PDU Session Setup RSP (step 22).

[0091] Among them, step 19 includes the core network sending a PDU bearer establishment request to the gNB, carrying a PDU session resource (PDUSessionResource) establishment list service request (SetupListSUReq), including uplink and downlink AMBR, UGW IP, fiveQI and E-RAB-ID. Step 20 includes the gNB sending an RRC reconfiguration message to the UE, and sending SRB2&DRB related information. Step 21 includes the UE replying to the gNB that the reconfiguration is complete. Step 22 includes the gNB replying to the core network that the PDU bearer establishment is complete.

[0092] Above Figure 6 The 5G signaling process shown ensures the stability and security of 5G communication and provides a solid foundation for subsequent data transmission. The 4G signaling process can refer to the above 5G signaling process and will not be described again.

[0093] For Wi-Fi communication systems, see Figure 7 , shows a typical Wi-Fi 802.11 protocol process. Figure 7 As shown in (a), the process generally includes three processes: detection, authentication, and association, as follows:

[0094] 1. Detection: The purpose of the detection phase is to scan the networks that currently support the 802.11 protocol in the area where the UE can communicate with the AP, so that the UE can obtain the capability information of each AP and decide whether to join the network where the AP is located. This process may include two frames: req (request frame) + rsp (reply frame), where req is the request frame sent by the UE to the AP (active), and rsp is the reply frame sent by the AP to the UE (passive).

[0095] 2. Authentication: After receiving the reply frame sent by the AP, the UE decides whether to join the network based on its own capability information and the capability information of the AP. If the UE decides to join the network, it sends an authentication (Auth) frame to the AP for identity authentication, otherwise the process ends. This process includes two frames: Auth frame 1 + Auth frame 2, where Auth frame 1 is the authentication frame sent by the UE to the AP, and Auth frame 2 is the authentication frame replied by the AP to the UE.

[0096] 3. Association: After receiving the Auth frame 2 replied by the AP, the UE identifies the successful authentication message contained in the Auth frame 2 and decides to join the network. At this time, the UE will send an Assoc Req frame to the AP, which specifies the network to join, the UE's Listen Interval, and the UE's capability information. The Listen Interval is how often the UE listens to the Beacon frame.

[0097] After receiving the Assoc Req frame sent by the UE, the AP confirms whether the Listen Interval of the UE is acceptable and whether the UE's capability information matches. If so, the AP replies to the UE with an Assoc Rsp frame 1, which carries the Association ID and success information, indicating that the UE and the AP are successfully associated. Otherwise, the AP replies to the UE with an Assoc Rsp frame 2, which carries the failure information, indicating that the UE and the AP have failed to associate. This process includes two frames: association request frame (ASSOC req) + association reply frame (ASSOC rsp).

[0098] like Figure 7 As shown in (b), the access process of Wi-Fi data link data is shown. The UE selects the AP through detection (discovery), and then after authentication and association, the UE establishes a connection with the AP. At this point, the UE communicates with the AP, and the AP can send and receive UE data.

[0099] like Figure 7 As shown in (c), the mapping relationship between the Wi-Fi data link layer and the physical layer is shown. The data link layer of 802.3 Local Area Network (LAN) (Ethernet) supports 802.2 Logical Link Control (LLC) and 802.3 Media Access Control (MAC), and the physical layer supports 802.3 Physical Layer Transceiver (PHY). The data link layer of wireless LAN supports 802.2LLC and 802.11MAC, and the physical layer supports 802.11PHY.

[0100] Next, a wake-up method provided in an embodiment of the present application is described in detail, which is applied to a terminal device (hereinafter referred to as UE), wherein the terminal device includes at least two communication modules, the at least two communication modules correspond to at least two communication systems, and the communication modules are used to support the communication between the terminal device and the network elements in the communication system corresponding to the communication modules. Figure 8The flowchart of the wake-up method shown in FIG. 1 includes steps S101 to S108, as follows:

[0101] Step S101: The UE determines whether it is in a multi-communication system connection state.

[0102] The multi-communication system connection state may refer to that the UE is connected to multiple communication systems at the same time.

[0103] In this embodiment, the UE can determine whether it is currently connected to the Wi-Fi communication system and the cellular communication system respectively. If the UE is connected to both the Wi-Fi communication system and the cellular communication system, that is, in a multi-communication system connection state, the UE can execute step S102.

[0104] Among them, the UE can determine whether it is connected to the cellular communication system by checking the RRC state. The UE can determine the connection status between the UE and the WIFI communication system by checking the name of the currently connected WIFI network, signal strength, and connection status. Specifically, the implementation of the UE determining whether it is connected to the communication system can refer to the existing technology and will not be described in detail.

[0105] Step S102: The UE reports capability information to the core network device.

[0106] Among them, the core network equipment can simultaneously connect to communication nodes in multiple communication systems, such as access network equipment, base stations, APs, etc. Figure 4 As described in, the core network device can simultaneously connect to a base station in a cellular communication system and to an AP in a Wi-Fi communication system.

[0107] Among them, the capability information is used to indicate the ability of the UE to receive a wake-up signal. Specifically, the ability of the UE to receive a wake-up signal may include whether the UE supports receiving a wake-up signal from a Wi-Fi communication system for waking up a cellular communication system, that is, whether it supports waking up the cellular communication module by receiving a wake-up signal from a Wi-Fi communication system when it is detected that there is a service to be sent to the UE in the cellular communication system. It should be understood that the use for waking up the cellular communication system mentioned in the present application can be replaced by a description of a cellular communication module corresponding to the cellular communication system. The wake-up signal for waking up the cellular communication system can be replaced by a description of a wake-up signal corresponding to the cellular communication system or a wake-up signal of the cellular communication system.

[0108] Specifically, the capability information may be a binary bit, where a binary bit 0 indicates that the receiving of a wake-up signal from a Wi-Fi communication system is supported, and a binary bit 1 indicates that the receiving of a wake-up signal from a Wi-Fi communication system is not supported. Alternatively, the capability information may be a Boolean value: true or false, where true indicates that the receiving of a wake-up signal from a Wi-Fi communication system is supported, and false indicates that the receiving of a wake-up signal from a Wi-Fi communication system is not supported.

[0109] It should be understood that the UE supports receiving wake-up signals from the Wi-Fi communication system, which means that the wake-up signal is generated by the core network device. The Wi-Fi communication system can judge the wake-up signal sent by the received core network device, and after judging that the wake-up signal has been received, it sends the wake-up signal to the main receiver of the cellular communication module of the UE.

[0110] Optionally, the UE may receive capability query information from the core network device, and report the capability information of the UE to the core network device in response to the capability query information. Accordingly, the core network device executes the following steps S201 to S203.

[0111] Step S103: The UE determines whether there is any service of the UE on each communication system.

[0112] Optionally, the UE may determine whether there is a UE service on the communication system in the following manner: In the connection mode, the UE may monitor the signaling and data packets from the base station or the core network. When the UE receives signaling or data packets related to its own service (such as paging messages, service establishment requests, etc.), it may determine whether there is a service related to itself based on the content of the signaling or data packets.

[0113] Further, when the UE determines that there are services of the UE on each communication system, it communicates with the device in the communication system through the communication module corresponding to the communication system to complete the current service, that is, executing step S104.

[0114] Step S104: Complete the current business.

[0115] For example, if there is a service for the UE on the cellular communication system, the UE communicates with the cellular communication system to complete the current service. Alternatively, if there is a service for the UE on the Wi-Fi communication system, the mobile phone communicates with the Wi-Fi communication system to complete the current service.

[0116] Further, if there is no service for the UE on the cellular communication system and there is service for the UE on the Wi-Fi communication system, the UE executes step S105.

[0117] Step S105: The UE enters the first state.

[0118] In this embodiment, the first state includes: turning off the first communication module corresponding to the first communication system in at least two communication modules, and keeping the second communication module in the at least two communication modules in the first working state. When the first communication system is a cellular communication system and the second communication system is a Wi-Fi communication system, the first state means that the Wi-Fi communication module of the UE is in the first working state and the cellular communication module is turned off. At this time, the UE can wake up the cellular communication module by receiving a wake-up signal from the Wi-Fi communication system.

[0119] The wake-up signal is used to wake up the cellular communication module in the UE to receive services from the cellular communication system. After receiving the wake-up signal from the Wi-Fi communication system, the UE can turn on the cellular communication module of the UE based on the wake-up signal.

[0120] Among them, the first working state of the Wi-Fi communication module may refer to a standby state. The communication module in the standby state will periodically turn on the receiver to receive network-side messages, such as turning on WUR to receive network-side messages. That is, after the UE enters the first state, the UE will detect whether the Wi-Fi communication module receives a wake-up signal and execute step S106.

[0121] Step S106: The UE detects whether the Wi-Fi communication module receives a wake-up signal.

[0122] In this embodiment, the UE may continuously detect whether the Wi-Fi communication module receives a wake-up signal. After the UE detects that the Wi-Fi communication module receives a wake-up signal, it further detects whether the wake-up signal includes a cellular wake-up signal, that is, executes step S107. The cellular wake-up signal is a signal used to wake up the cellular communication module.

[0123] If the UE does not detect that the Wi-Fi communication module receives the wake-up signal, the process continues to execute step S105.

[0124] Step S107: The UE detects whether the received wake-up signal includes a cellular wake-up signal.

[0125] The wake-up signal usually includes specific information for instructing the UE to wake up its cellular communication module and start preparing for communication. The present application does not limit the design form of the specific information, which may be a tag information, such as tag information for identifying a cellular communication system, or other information.

[0126] For example, UE2 initiates a call request to UE1. Since the telephone service is a cellular service, UE1 receives a wake-up signal from the Wi-Fi communication system, which includes a signal for waking up the cellular communication module (ie, a cellular wake-up signal).

[0127] After detecting that the wake-up signal from the Wi-Fi communication system includes a cellular wake-up signal, the UE executes step S108.

[0128] After detecting that the wake-up signal from the Wi-Fi communication system does not include a cellular wake-up signal, the UE proceeds to step S106.

[0129] Step S108: The UE turns on the cellular communication module to communicate with the base station.

[0130] The UE turns on the cellular communication module and receives paging messages from the base station and / or core network equipment. If the UE is successfully paged, the UE connects to the corresponding base station. After the UE is connected to the base station, the current service is completed. For example, after UE1 is connected to the base station, UE1 establishes a communication connection with UE2 through the base station, starts data transmission, and completes the call with UE2.

[0131] The execution steps on the UE side are introduced above. For the core network device, when the UE establishes connections with the Wi-Fi communication system and the cellular communication system respectively, the core network device also establishes connections with the AP in the Wi-Fi communication system and the base station in the cellular communication system respectively. In the wake-up method, applied to the core network device, the method may include steps S201-S203:

[0132] Step S201: The core network device receives capability information reported by the UE.

[0133] Furthermore, the core network device saves the received terminal capability information, for example, the terminal identifier and the capability information are stored in correspondence locally in the core network device.

[0134] Furthermore, the core network device registers the UE, wherein the process of registering the UE can refer to the existing technology and will not be described in detail.

[0135] Step S202: The core network device detects whether there is any UE service to be delivered on the cellular communication system.

[0136] After receiving and registering the capability information reported by the UE, the core network device can continuously detect whether there is any service to be issued on the cellular communication system. If there is no service for the UE, the core network device maintains the current state, that is, continues to detect whether there is any service to be issued on the cellular communication system.

[0137] In this embodiment, if there is no service to be sent on the cellular communication system, then the UE enters the first state, and the cellular communication module of the UE is turned off or in a silent state. Among them, the specific steps for the core network device to control the cellular communication module of the UE to be in a silent state are as follows: When the core network device detects that the data service and telephone service on the cellular communication system of the UE are not turned on, the core network device can control the gNB to send an uplink and downlink silence request to the UE. Among them, the uplink and downlink silence request is used to request silence of the cellular communication module of the UE. The uplink and downlink silence request may include UE AMBR, mobility-RestrictionList, UE-securityCapabilities, coreNetworkAssistanceInformationForInactive and other information elements.

[0138] Furthermore, the gNB sends an indication to the UE to query the UE capability information, which includes the freqBandinformation information element. After receiving the indication sent by the gNB, the UE replies to the gNB with the UE capability information, including the capabilities supported by PDCP / RLC / MAC / PHY and RF. After receiving the UE capability information, the gNB transparently transmits the UE capability information to the core network device.

[0139] Then, the gNB sends a security mode setting indication to the UE, including the encryption algorithm and integrity algorithm. After receiving the setting indication sent by the gNB, the UE performs security mode setting and sends a reply message to the gNB after the security mode setting is completed, indicating that the security mode encryption is completed.

[0140] After receiving the reply message sent by the UE, the gNB sends an RRC reconfiguration message to the UE to activate BWP1. After receiving the RRC reconfiguration message sent by the gNB, the UE performs a series of RRC reconfiguration operations and replies to the gNB that the RRC reconfiguration is complete. After receiving the RRC reconfiguration completion message from the UE, the gNB sends a response to the core network device that the UE uplink and downlink establishment is complete.

[0141] After receiving the response from the gNB, the core network device sends a PDU bearer establishment request to the gNB, carrying PDUSessionResource SetupListSUReq, including uplink and downlink AMBR, UGW IP, fiveQI and E-RAB-ID.

[0142] After receiving the PDU bearer establishment request sent by the core network device, the gNB sends an RRC reconfiguration message to the UE, as well as SRB2&DRB related information. After receiving the message sent by the gNB, the UE completes the resource configuration and replies to the gNB that the configuration silent setting is completed. At this time, the UE's cellular communication module is in silent state.

[0143] Further, after the cellular communication module of the UE is in a silent state, if the core network device detects that the base station has services of the UE to be sent, step S203 is executed.

[0144] Step S203: The core network device wakes up the UE through the Wi-Fi communication system.

[0145] Specifically, the core network device sends a wake-up signal to the Internet, and the Internet finds the AP corresponding to the UE and sends a wake-up signal. The AP then sends a wake-up signal to the Wi-Fi network, and the Wi-Fi network determines whether the received message is for a cellular wake-up signal.

[0146] If yes, the Wi-Fi network replies a confirmation message to the AP. After receiving the confirmation message from the Wi-Fi network, the AP sends a message to the core network device, which indicates that the Wi-Fi network where the UE is located confirms that the cellular baseband signal of the UE needs to be awakened. After receiving the message, the core network device determines the target base station where the UE is located and sends a message to the target base station. After receiving the message, the target base station sends a paging signal to the UE.

[0147] The specific steps for the core network device to control the Wi-Fi communication system to wake up the UE with cellular OSI data are as follows: after the core network device detects that there is a service to be sent from the base station, it finds the AP corresponding to the UE through the Internet and sends a wake-up signal. Then, after receiving the wake-up signal, the AP sends specific broadcast information on the PBCH channel through the Wi-Fi frame structure data, where the specific broadcast information may refer to a demodulation reference signal (DM-RS).

[0148] After receiving the specific frame structure signal (GP / 14ofdm / 30k SCS) of the broadcast signal, the Wi-Fi network immediately compares it with the stored interface A signal. If the two are determined to be consistent, the cellular baseband signal is immediately awakened. The interface A signal refers to a set of specific data stored in the Wi-Fi network device. The Wi-Fi network can compare the received specific frame structure signal with the stored interface A signal. If the received signal is consistent with the event type contained in the interface A signal, the judgment threshold is triggered, and the Wi-Fi network will perform the corresponding operation.

[0149] In this embodiment, a judgment condition for a wake-up signal may be pre-set in the Wi-Fi network. When a received signal meets the above judgment condition, it indicates that the signal is a wake-up signal.

[0150] After the Wi-Fi network determines that it is a wake-up signal, it sends the generated signaling message to the AP, and the AP public gateway reports the received signaling message to the core network device. After receiving the signaling message reported by the AP public gateway, the core network device parses the signaling message and determines the target cellular base station. Then, the core network device allocates the signaling transmission to the target cellular base station, and the target cellular base station sends the signaling message to the UE, which contains the paging signal.

[0151] Then, after receiving the paging signal from the target cellular base station, the UE activates the uplink of the PRACH channel and the PUCCH channel, and performs a base station query, that is, sends a query message to the base station. After receiving the query message from the UE, the base station transmits the query message to the core network device. Then, the core network device can determine whether the UE is the target UE by the UE identifier contained in the reported query message. If the core network device determines that the UE is the target UE, the core network device controls the base station to perform another PSS / SSB scan to complete the acquisition and comparison of the UE information, and determine the RRC conditions and base station allocation strategy. The base station will allocate corresponding wireless resources to the UE according to the current resource allocation strategy to ensure that the UE can smoothly switch out of the silent state. At this time, the UE completes the wake-up and switches out of the silent state.

[0152] Therefore, the UE switches the cellular communication module from the silent state to the working state based on the wake-up signal, that is, turns on the cellular communication module to achieve communication with the base station.

[0153] Furthermore, the method described in the present application also includes: in response to no business occurring between the first communication node and the first communication system, and between the first communication node and the second communication system, triggering the first communication node to be in the second state; the second state includes: shutting down the first communication module, keeping the second communication module in the second working state; the power consumption of the second communication module in the second working state is higher than the power consumption in the first working state. Receiving an inquiry message from the second communication system; the inquiry message is used to inquire whether there is a business to be transmitted through the first communication system and / or the second communication system on the first communication node; turning on the first communication module and / or the second communication module according to the inquiry message.

[0154] The following describes the process by taking the example that the cellular communication module and the Wi-Fi communication module have no business with the UE at the same time:

[0155] Due to the current usage habits of customers and statistics of data scenarios, it is rare that the cellular communication module and the Wi-Fi communication module are in silent state at the same time. Among them, if the cellular communication module and the Wi-Fi communication module are in silent state at the same time, it can be considered that the cellular communication module and the Wi-Fi communication module are both turned off, and the UE enters a low-power silent state. Furthermore, if there is no UE service in both the cellular communication system and the Wi-Fi communication system, a QoS AP scheduling mode can be adopted, that is, the AP is set to detect in certain frames to ensure that the Wi-Fi data service will not be interrupted.

[0156] Specifically, when the core network device detects that there is no service on the cellular communication system and the Wi-Fi communication system, a preset time period can be set. The preset time period can be, for example, 30S, 40S, etc. Then, if there is no service on the cellular communication system and the Wi-Fi communication system after the preset time period, the UE enters a silent state. At this time, the AP to which the UE is connected will inquire the UE in a specific time frame (Frame), that is, send an inquiry message to the UE to inquire whether there is any service on the cellular communication system and / or the Wi-Fi communication system of the UE. After receiving the inquiry message from the AP, the UE will make an acknowledgment (ACK) reply, that is, reply a confirmation message to the AP, which indicates whether the UE has services on the Wi-Fi communication system and / or the cellular communication system. After receiving the confirmation message, the AP will send a message to the core network device, which indicates whether the UE has services on the Wi-Fi communication system and / or the cellular communication system.

[0157] See also Fig. 9 , Fig. 9 A schematic diagram of a time frame is shown. Fig. 9 As shown, the UE can select a frame from Frame1-FrameN as a specific frame and set a query task in the specific frame. The UE can flexibly set the specific position of the query task in the Frame, which will not be described in detail here.

[0158] If the UE has no service on the Wi-Fi communication system and / or the cellular communication system, the UE continues to maintain the silent state.

[0159] If the confirmation message indicates that there are services on the Wi-Fi communication system and / or the cellular communication system in the UE, the AP sends an inquiry message to the UE to inquire whether the Wi-Fi communication module needs to be activated. After receiving the inquiry message, the UE replies to the AP, indicating in the reply message whether the UE needs to activate the baseband signal of the Wi-Fi communication module. Then, after the UE activates the baseband signal of the Wi-Fi communication module, the UE can perform channel preparation and information reporting, power control, etc., and prepare for data interaction. At this time, the UE enters the working mode, that is, the UE's Wi-Fi communication module enters the working mode.

[0160] If the UE has services on the Wi-Fi communication system, the Wi-Fi communication module of the UE communicates with the AP to complete the services on the Wi-Fi communication system after entering the working mode. If the UE has services on the cellular communication system, the Wi-Fi communication module of the UE turns on the cellular communication module according to the received wake-up signal to complete the services on the cellular communication system after entering the working mode.

[0161] If the service ends after a preset time period, the UE can enter a low-power silent state again, thereby further reducing the power consumption of the UE.

[0162] In summary, when there is no business between the terminal and the first communication system in at least two communication systems, the terminal turns off the first communication module corresponding to the first communication system, and keeps the second communication module in the at least two communication modules in a working state, the second communication module is a communication module with power consumption less than a preset threshold among the at least two communication modules, and the second communication module is used to receive a wake-up signal corresponding to the first communication system. As a result, the terminal only needs the communication module with low power consumption to be in a working state, and the other communication modules are all turned off, or it can be considered that the other communication modules are in deep sleep, which can save the power consumption of the terminal.
