It should be noted that in the embodiments of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0060] The core network equipment may include but is not limited to at least one of the following: core network node, core network function, mobility management entity (Mobility Management Entity, MME), access mobility management function (Access and Mobility Management Function, AMF), session management function (Session Management Function, SMF), user plane function (User Plane Function, UPF), policy control function (Policy Control Function, PCF), policy and charging rules function unit (Policy and Charging Rules Function, PCRF), edge application service discovery function (Edge Application Server Discovery Function, EASDF), unified data management (Unified Data Management, UDM), unified data storage (Unified Data Repository, UDR), home user server (Home Subscriber Server, HSS), centralized network configuration (CNC), network storage function (Network Repository Function, NRF), network exposure function (Network Exposure Function, NEF), local NEF (Local NEF, or L-NEF), binding support function (Binding Support Function, BSF), application function (Application Function, AF), etc. It should be noted that in the embodiments of the present application, only the core network device in the NR system is introduced as an example, and the specific type of the core network device is not limited.

[0061] In some embodiments, the terminal and the network side device can refer to Figure 2 As shown, the terminal includes a main communication module and an extremely low power consumption communication module, and the network side device includes a main communication module and an extremely low power consumption communication module. The main communication module and the extremely low power consumption communication module can communicate with each other, and the extremely low power consumption communication module of the terminal can communicate with the extremely low power consumption communication module of the network side device. It should be noted that Figure 2 This is just an example. For example, in some embodiments, the main communication module of the terminal can communicate with the main communication module of the network side device. In some embodiments, the ultra-low power consumption communication module of the terminal can communicate with the main communication module of the network side device.

[0062] In some embodiments, the main communication module can support traditional communication modes (such as 4G, 5G, 6G, etc.) and communication technologies for mobile broadband (MBB) or enhanced mobile broadband (eMBB) scenarios; for example: 5G NR technology that supports orthogonal frequency division multiplex (OFDM) communication, including uplink and / or downlink communication.

[0063] In some embodiments, the extremely low power communication module can support extremely low power communication (such as supporting sending signals by backscatter) or support low power reception, for example: the extremely low power communication module includes a low power receiving module, such as a low power wake-up receiver. For sending signals by backscatter, the excitation source signal can be generated by the terminal with the extremely low power communication module itself or by other devices. For example: in the case where the above-mentioned extremely low power communication module is a backscatter communication module, the main communication module will naturally excite the extremely low power communication module when sending signals, so the additional backscatter signal generated has almost no additional overhead.

[0064] In some embodiments, the extremely low power communication may include at least one of the following:

[0065] Supports backscatter communication for energy harvesting;

[0066] Support powered backscatter communications;

[0067] Low power reception.

[0068] For example: Ultra-low power communication modules can support energy harvesting, including but not limited to harvesting energy from light, solar energy, wireless signals, etc.

[0069] In addition, the excitation source signal of the backscatter communication may be generated by the terminal itself with the extremely low power consumption communication module or by other devices.

[0070] In some embodiments, extremely low power communication may refer to communication whose power consumption is significantly lower than that of the main communication module. For example, communication of a communication module whose power consumption is generally tens of microwatts to hundreds of microwatts is extremely low power communication, while the power consumption of the main communication module is generally tens of milliwatts to thousands of milliwatts, and the cost of the extremely low power communication module is also significantly lower than that of the main communication module.

[0071] Backscatter communication is the most representative technology for ultra-low power communication. In principle, backscatter communication equipment controls the reflection coefficient of the circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the RF signal from other devices or the environment to achieve signal modulation. Typical backscatter communication hardware modules can be as follows: Figure 3 As shown, it includes: antenna unit, energy collection module or energy supply module, microcontroller, signal receiving module, channel coding and modulation module, memory or sensor module, etc. Among them, the signal receiving module is responsible for receiving the downlink signal sent to the backscattering device by the network side device or card reader, etc. Its architecture and technology can reuse the low-power wake-up receiver technology defined in the protocol or newly defined in the future; since backscatter communication does not actively generate radio frequency signals, its energy consumption is extremely low, usually between tens of microwatts and hundreds of microwatts, and the energy collection module can collect energy such as radio frequency signals, light energy, thermal energy, etc. in the environment to modulate, demodulate and reflect the signal, without having its own energy source such as batteries; it can also be supplied by small energy supply modules such as button batteries, thereby reducing the strength requirements of the energy supply signal. In addition to the above typical components, backscatter communication technology can integrate low-power amplifier modules to improve receiving sensitivity and backscatter signal power.

[0072] It should be noted that in the embodiments of the present application, backscatter communication is only an example of extremely low power consumption communication. In the embodiments of the present application, there is no limitation on extremely low power consumption communication. For example, it may be extremely low power consumption communication defined in the protocol, such as communication of a communication module with power consumption ranging from tens of microwatts to hundreds of microwatts.

[0073] In combination with the accompanying drawings, a state switching method, apparatus, terminal and network side equipment provided by the embodiments of the present application are described in detail through some embodiments and their application scenarios.

[0074] See also Figure 4 , Figure 4 is a flow chart of a state switching method provided in an embodiment of the present application, such as Figure 4 As shown, the following steps are included:

[0075] Step 401: The terminal switches from a source state to a target state, wherein the source state is a state in at least one of a first state set, a second state set, and a third state set, and the target state is another state in at least one of the first state set, the second state set, and the third state set;

[0076] Wherein, the terminal includes a first communication module and a second communication module;

[0077] The first state set includes: multiple states of the first communication module when the first communication module is enabled and the second communication module is not enabled;

[0079] The third state set includes multiple states, each state is used to represent a state of the first communication module and the second communication module.

[0080] Among them, at least one state set among the above-mentioned first state set, second state set and third state set is at least one state set supported by the above-mentioned terminal, for example: the terminal supports the above-mentioned first state set and second state set, or the terminal supports the above-mentioned first state set and third state set, or the terminal supports the above-mentioned three state sets.

[0081] The switching from the source state to the target state includes at least one of the following:

[0091] In some embodiments, the first communication module may be one of an extremely low power communication module and a main communication module, and the second communication module may be the other of the extremely low power communication module and the main communication module. For example, the first communication module is the main communication module, and the second communication module is the extremely low power communication module, or the second communication module is the main communication module, and the first communication module is the extremely low power communication module. The extremely low power communication module is a module that supports extremely low power communication, and the power consumption of the main communication module is higher than that of the extremely low power communication module.

[0092] In some embodiments, the first communication module and the second communication module are two different extremely low power consumption communication modules. For example, the first communication module and the second communication module are communication modules that can send signals in the form of backscattering and actively generate carrier waves. For example, the first device is an IoT terminal with two communication modes, such as an IoT terminal that can send signals in the form of backscattering and actively generate carrier waves.

[0093] Each state in the above-mentioned first state set represents the state of the first communication module when the first communication module is enabled and the second communication module is not enabled. It can be understood that each state in the first state set is not associated with the second communication module;

[0094] Each state in the second state set represents the state of the second communication module when the second communication module is enabled. It can be understood that each state in the second state set is not associated with the first communication module, and when the terminal is in a state in the second state set, the first communication module may be enabled or not enabled;

[0095] The third state set includes each state for representing the state of the first communication module and the second communication module, that is, the state of the first communication module and the second communication module can be determined by any state in the third state set, and the state in the third state set can also be called the combined state of the two modules or the two-dimensional state.

[0096] In the embodiment of the present application, since the terminal includes a first communication module and a second communication module, and switches from a source state to a target state, the terminal supports state switching of the two communication modules, and further supports the operation of the two communication modules to improve the transmission performance of the terminal.

[0097] In some embodiments, by switching between the states included in the first state set, the second state set, and the third state set, the terminal can switch from a state in which the first communication module and the second communication module communicate simultaneously to a state in which at least one of the first communication module and the second communication module communicates, and from a state in which at least one of the first communication module and the second communication module communicates to a state in which the first communication module and the second communication module communicate simultaneously, thereby supporting simultaneous communication between the two communication modules and thereby improving the transmission reliability or transmission rate of the terminal.

In other embodiments, in the state in the second state set, the first communication module may also be enabled.

[0139] The state in which the above-mentioned second communication module is connected to the other end indicates the state in which the terminal can communicate with the other end through the second communication device, and the state in which the above-mentioned second communication module is abnormal indicates that the second communication module is enabled but is in an abnormal state, which can be a state between the fourth state and the sixth state, that is, when the second communication module is enabled, if the second communication module is not in the above-mentioned fourth state and sixth state, it is in the above-mentioned fifth state.

[0140] The state in which the second communication module is disconnected from the opposite end indicates that the connection between the terminal and the opposite end through the second communication module is disconnected.

[0141] In this implementation, the state switching related to the second communication module can be implemented to improve the flexibility of the terminal state switching.

[0142] Optionally, the state in which the second communication module is connected to the other end includes a state in which the terminal performs at least one of the following:

[0144] Storing an AS context, wherein the AS context includes an AS context related to the second communication module;

[0145] Reporting cell information to the other end through the second communication module;

The above-mentioned LP-RAN can be a RAN that provides services for extremely low power consumption communication devices / modules, and the corresponding protocol stack and other aspects are the same or different from general RAN, and can provide the extremely low power consumption communication module with the carrier required for Backscatter.

[0149] In some implementations, LP-RAN refers to a RAN corresponding to an extremely low power consumption communication module. LP-RAN and RAN may be the same network entity.

[0150] The AS context is stored in the terminal, and the LP-RAN also stores the AS context, that is, the AS context and the terminal store the AS context. The AS context can be a complete AS context or an AS context related only to low power communication.

[0151] By reporting the cell information to the opposite end through the second communication module, the LP-RAN can know the cell to which the terminal belongs.

[0152] At least one of the unicast information, broadcast information and multicast information transmitted through the second communication module may be LP-RAN transmitting unicast, broadcast or multicast information to or from the terminal, and such information may include control signaling and broadcast messages. In the case where the second communication module is an extremely low power consumption communication module of the device A / B type, when the LP-RAN needs to receive information from the terminal, the LP-RAN can also provide the carrier required for Backscatter to the device. For all types of extremely low power consumption communication modules, whether receiving or sending signals, the LP-RAN can also send the radio frequency signal required for energy collection to the terminal to assist in completing the communication.

[0153] The measurement performed by the second communication module may be a measurement included in the mobility management controlled by the network, for example: receiving a synchronization signal block (SSB) sent by the LP-RAN through the second communication module, or measuring the SSB or other terminal-specific reference signals sent by the LP-RAN, reporting a mobility measurement report to the LP-RAN, and receiving mobility management-related control signaling of the LP-RAN to complete the cell switching.

[0154] When the second communication module is connected to the other end, a connection between LP-RAN and the core network can also be established, wherein the core network may be the same as a common core network or may be a core network designed specifically for low-power communication.

Alternatively, the above mobility management or cell reselection is autonomously controlled by the terminal.

[0170] In the above state, the LP-RAN and the terminal store the AS context.

[0172] At least one of the unicast information, broadcast information and multicast information transmitted through the second communication module may be unicast, broadcast or multicast information transmitted by LP-RAN to or from the terminal, and such information includes control signaling and broadcast messages. In addition, in addition to such information, LP-RAN may also transmit a radio frequency carrier to the terminal for energy collection or backscatter.

[0174] In the above state, a LP-RAN-core network connection may also be established for the terminal.

[0175] The fact that the second communication module is not used when the second communication module is in an abnormal state may be understood as that the second communication module does not perform the above operations in the above state, and only the first communication module performs related operations.

[0176] In this implementation manner, when the second communication module is in an abnormal state, the terminal can execute at least one of the above items, thereby improving the communication performance of the terminal.

[0301] The first communication module is enabled, the first communication module is disconnected from the radio access network, and the first communication module is disconnected from the radio access network and the core network; or

[0302] The first communication module is not enabled;

[0303] or,

[0304] The state in which the second communication module is disconnected from the other end includes:

[0305] The second communication module is enabled and disconnected from the peer end; or

[0306] The second communication module is not enabled.

[0307] In this implementation, the first communication module being disabled can be defined as a state where the first communication module is disconnected from the wireless access network, and the connection between the wireless access network and the core network of the first communication module is disconnected. The second communication module being disabled can be defined as a state where the second communication module is disconnected from the opposite end, thereby saving state management overhead. For example, the first state to the sixth state and other states where there is an idle state are merged, that is, the case where one of the modules is disabled is regarded as an idle state, or vice versa. At this time, the module in the idle state is actually equivalent to not turning on the module, and it is impossible to receive paging, and it is impossible to perform operations such as mobility management, PLMN selection, and receiving system messages.

[0308] In some implementations, it may be assumed that both the first communication module and the second communication module need to be turned on, so that the first state to the sixth state may be removed to save state management overhead.

[0309] In some embodiments, the first state (such as the inactive state) or the fifth state (such as the abnormal state) can also be deleted. The introduction of the first state is mainly to maintain the context on the network side while reducing the power consumption of the terminal, and to reduce the delay when the terminal is activated again. The first communication module can maintain long-term connectivity and context continuity with the network side with lower power consumption, and overlaps with the role of the inactive state to a certain extent. Therefore, the first state can be deleted. When the second communication module is in the fifth state, it can be degraded to the fifth state for processing, but it should be noted that when the terminal enters the fifth state, the second communication module may only be busy or temporarily low in power, and the connection is not completely lost. Therefore, although the benefit is that the state setting can be simplified, unnecessary overhead for restoring the connection may be generated.

[0310] It should be noted that the above-mentioned state optimization methods can be used individually, partially (for example, only deleting / merging a part of the states) or in combination.

[0311] As an optional implementation manner, the terminal switches from a source state to a target state, including:

[0312] The terminal switches from a source state to a target state when a target condition is met, wherein the target condition is associated with at least one of the first communication module and the second communication module.

[0313] The above target conditions are conditions agreed upon in the protocol, or conditions determined by the terminal itself, and different conditions may correspond to different state switches.

[0314] In this implementation, switching from the source state to the target state can be triggered based on the target condition, so as to improve the accuracy of the state switching.

[0315] It should be noted that, in some implementation modes, the terminal may decide to perform the above switching on its own, that is, the above target condition may not be defined.

[0529] See also Figure 6 , Figure 6 is a flow chart of another state switching method provided in an embodiment of the present application. Figure 6 As shown, the following steps are included:

[0530] Step 601: A core network element performs CM state switching for a terminal, where the terminal includes a first communication module and a second communication module, and the CM state switching includes switching between states with the terminal as a granularity, or the CM state switching includes switching between states with the communication module of the terminal as a granularity;

[0531] The switching between states based on the terminal as the granularity includes:

[0532] Switching between a first CM connected state and a first CM idle state, wherein the first CM connected state represents at least one of the following:

[0533] The first communication module is disconnected from the wireless access network, and the wireless access network and the core network maintain a connection with the first communication module; or the first communication module remains connected to the wireless access network;

[0534] The second communication module is connected to the other end, or the second communication module is abnormal;

[0535] The first CM idle state indicates at least one of the following:

[0536] The first communication module is disconnected from the radio access network, and the radio access network is disconnected from the core network;

[0537] The second communication module is disconnected from the other end.

[0538] Among them, the above-mentioned core network network elements can be core network network elements such as AMF, MME or AMF, which is not limited in the embodiments of the present application.

[0539] The above-mentioned state with the terminal as the granularity can be understood as there is only one CM state for a terminal in the core network. For example, as long as one module is in a connected state, an inactive state or an abnormal state, the terminal establishes a signaling connection with the AMF, corresponding to the first CM connected state, otherwise, it corresponds to the first CM idle state. Switching between states with the terminal as the granularity can switch the state management overhead.

[0540] The switching between states based on the communication module of the terminal can be understood as defining corresponding CM states for the first communication module and the second communication module, respectively, or defining corresponding CM combination states for the first communication module and the second communication module. Switching between states based on the communication module of the terminal can achieve more refined state switching, which is conducive to improving the transmission performance of the terminal.

[0541] In this embodiment, since the terminal includes a first communication module and a second communication module, CM state switching is performed on the terminal, so that communication between the first communication module and the second communication module of the terminal can be supported on the core network side, thereby improving the transmission performance of the terminal.

[0542] Optionally, the communication module of the terminal switches between states of granularity, including at least one of the following:

[0543] Switching between at least two of a second CM connected state, a second CM idle state, a third CM connected state, and a third CM idle state;

[0544] Switching between a fourth CM connected state and a fifth CM idle state;

[0545] The second CM connection state indicates that: the first communication module is disconnected from the wireless access network, and the wireless access network and the core network maintain a connection with the first communication module; or, the first communication module maintains a connection with the wireless access network;

[0546] or,

[0547] The second CM idle state indicates that the first communication module is disconnected from the radio access network, and the radio access network is disconnected from the core network.

[0548] or,

[0549] The third CM connection state indicates that: the second communication module is connected to the opposite end, or the second communication module is abnormal;

[0550] or,

[0551] The third CM idle state indicates that the second communication module is disconnected from the opposite end;

[0552] or,

[0553] The fourth CM connection state includes at least one of the following:

[0554] a first CM connection combination state, a second CM connection combination state, a third CM connection combination state, and a fourth CM connection combination state;

[0555] The first CM connection combination state indicates that the first communication module is not enabled, and the second communication module is in a CM connection state;

[0556] The second CM connection combination state indicates that the first communication module is disconnected from the wireless access network, and the connection between the wireless access network and the core network is disconnected from the first communication module, and the second communication module is in the CM connection state;

[0557] The third CM connection combination state indicates that the first communication module is disconnected from the wireless access network, the wireless access network and the core network maintain a connection with the first communication module, and the second communication module is in a CM connection state;

[0558] The fourth CM connection combination state indicates that the first communication module is connected to the wireless access network, and the second communication module is in a CM connection state;

[0559] Or, the fourth CM idle state includes at least one of the following:

[0560] a first CM idle combination state, a second CM idle combination state, a third CM idle combination state, and a fourth CM idle combination state;

[0561] The first CM idle combined state indicates that the first communication module is not enabled, and the second communication module is in a CM space state;

[0562] The second CM idle combined state indicates that the first communication module is disconnected from the wireless access network, and the connection between the wireless access network and the core network is disconnected from the first communication module, and the second communication module is in the CM space state;

[0563] The third CM idle combined state indicates that the first communication module is disconnected from the wireless access network, the wireless access network maintains a connection with the core network with the first communication module, and the second communication module is in the CM space state;

[0564] The fourth CM idle combined state indicates that the first communication module maintains connection with the wireless access network, and the second communication module is in a CM space state.

[0565] Among them, the second CM connected state, the second CM idle state, the third CM connected state and the third CM idle state are CM states with module granularity. For example: two CM states are defined respectively, corresponding to two modules respectively. Among them, when the RRC state of the first communication module is connected state or inactive state, the CM state of the module is connected state, otherwise it is idle state. When the RRC state of the second communication module is connected state or abnormal state, the CM state of the module is connected state, otherwise it is idle state.

[0566] The state switching between modules can be realized through the second CM connected state, the second CM idle state, the third CM connected state and the third CM idle state, thereby supporting more flexible state switching of the terminal, which is beneficial to improving the transmission performance of the terminal.

[0567] The fourth CM connection state and the fifth CM idle state are combined states defined for the first communication module and the second communication module. In the fourth CM connection state and the fifth CM idle state, only the CM state needs to be defined for the second communication module, thereby saving the state management overhead. For example, as shown in Table 2 below:

[0568] Table 2:

[0569] CM idle state CM connected state Not Enabled (Not enabled, idle state) (Not enabled, CM connected) RRC Idle State (RRC idle state, CM idle state) (RRC idle state, CM connected state) RRC inactive state (RRC inactive, CM idle) (RRC inactive, CM connected) RRC connected state (RRC connected state, CM idle state) (RRC connected state, CM connected state)

[0570] The RRC idle state represents the second state of the first communication module, the RRC inactive state represents the first state of the first communication module, and the RRC connected state represents the third state of the first communication module.
