[0060] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0061] First, refer to Figure 1 Overview of application scenarios according to embodiments of this disclosure.

[0062] Figure 1 This is a schematic diagram illustrating an application scenario of the mobility handover method according to an embodiment of the present disclosure. For example... Figure 1 As shown, the application scenario includes at least: terminal device (e.g., UE10) and one or more network devices (e.g., serving cell 11, target cell 12, candidate cell 13).

[0063] The terminal device can be mobile or fixed. One or more network devices are devices that can communicate with the terminal device via a wireless link. The network device can cover a cell and provide network services to the cell, and can communicate with the terminal device located in the corresponding coverage cell. Therefore, the network device is sometimes referred to as a cell.

[0064] It is worth noting that the technologies described in this disclosure are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA), or other systems. The terms "system" and "network" in this disclosure are often used interchangeably, and the described technologies can be used with the systems and radio technologies mentioned above, as well as with other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and the term NR is used in most of the following description; however, these technologies can also be applied to systems other than NR systems, such as 6th Generation (6G) communication systems.

[0065] Among them, terminal devices can be mobile phones, tablet computers, laptop computers, laptops, personal digital assistants (PDAs), handheld computers, netbooks, ultra-mobile personal computers (UMPCs), mobile internet devices (MIDs), augmented reality (AR) devices, virtual reality (VR) devices, robots, wearable devices, flight vehicles, vehicle user equipment (VUEs), shipboard equipment, pedestrian user equipment (PUEs), smart home devices (home devices with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), game consoles, personal computers (PCs), ATMs, or self-service machines, etc. Wearable devices include: smartwatches, smart bracelets, smart earphones, smart glasses, smart jewelry (smart bracelets, smart necklaces, smart anklets, smart ankle chains, etc.), smart wristbands, smart clothing, etc. Among these, in-vehicle devices can also be referred to as in-vehicle terminals, in-vehicle controllers, in-vehicle modules, in-vehicle components, in-vehicle chips, or in-vehicle units, etc. It should be noted that the specific type of terminal device is not limited in the embodiments disclosed herein.

[0066] Network equipment can be a device that communicates with terminal devices. Specifically, network equipment can provide communication coverage within a certain area and communicate with terminals located within that area. Optionally, network equipment can be a base station in various communication systems, such as an evolved Node B (eNB) in an LTE system, or a gNB in ​​a 5G or NR system, or a centralized base station unit (gNB-CU) or a distributed base station unit (gNB-DU).

[0067] The base station can be gNB, gNB-CU, gNB-DU, or any other suitable term in the field, as long as the same technical effect is achieved. The base station is not limited to specific technical terms. It should be noted that the embodiments of this disclosure only use the base station in the NR system as an example for introduction, and do not limit the specific type of base station.

[0068] During the movement of UE10, in order to ensure smooth communication, a mobility handover will occur, i.e., switching from the current serving cell 11 to the target cell 12 or the candidate cell 13. Therefore, in this disclosure, the network equipment is further subdivided into a first network equipment, a second network equipment, and a third network equipment. Among them, the first network equipment can be understood as the serving base station, the source base station, the serving cell, etc., that is, the cell that UE10 is currently connecting to and communicating with; the second network equipment can be understood as the target cell, that is, the cell that UE10 is about to hand over to or reselect, which is called the target cell. The target cell is usually selected from the candidate cells according to certain criteria (such as signal strength, quality, cell load, etc.); the third network equipment can be understood as the candidate cell, that is, the cells around UE10 that may become the target cell. These cells are usually the neighboring cells of the serving cell, and UE10 will perform signal measurement and evaluation on them.

[0069] Mobility handover can include traditional handover (HO), Layer-1 / Layer-2 Triggered Mobility (LTM), Conditional Handover (CHO), and other handover mechanisms.

[0070] Among them, HO is a traditional handover method, which is a handover process triggered and controlled by the network based on the measurement report reported by UE10 and a series of predefined handover criteria (such as thresholds).

[0071] LTM refers to mobility handover triggered by the physical layer (i.e., layer 1) or the data link layer (i.e., layer 2). In wireless communication systems, when the aforementioned network equipment is a base station (e.g., gNB), the terminal equipment will handover between different cells. Based on the base station to which the cells belong before and after the handover, LTM handover can be performed between different cells within the same base station (intra-gNB) or between cells of different base stations (inter-gNB).

[0072] CHO (Crossover Event) is a handover method where handover conditions are predefined for UE10 during the network configuration phase. These conditions can be based on UE10's location, signal strength, quality, and other relevant parameters. For example, the network can configure UE10 with the following condition: when UE10's location is close to the boundary between two cells, and a certain measurement value of both the serving cell and the target cell simultaneously reaches a preset standard, UE10 can autonomously trigger a handover to the target cell without waiting for further instructions from the network. The following will refer to... Figures 2-7 The mobility handover method according to embodiments of this disclosure will be described in detail.

[0073] Figure 2This is a flowchart illustrating a mobility handover method according to an embodiment of the present disclosure. Figure 2 As shown, the mobility handover method applied to the first network device may include at least the following steps.

[0074] In step S201, a first message is sent to the terminal device, wherein the first message is used to instruct the terminal device to perform a state or function switch, and the terminal device is in energy-saving state or has the energy-saving function enabled.

[0075] As described above, this disclosure aims to address the problem of transmission performance loss caused by existing cell reselection methods when a UE10 in energy-saving mode requires data transmission during mobility. To address this, this disclosure proposes an early state transition method, which involves prematurely transitioning a UE in energy-saving mode or with energy-saving functionality enabled to connected mode before performing mobility handover, thereby reducing transmission performance loss.

[0076] Specifically, the serving cell 11 can send a first message to the UE10, which is currently in energy-saving mode or has energy-saving function enabled. The first message is used to instruct the UE10 to perform a state or function transition.

[0077] Furthermore, the serving cell 11 can decide to send the aforementioned first message to the UE10, which is in power-saving mode or has power-saving function enabled, based on the first measurement result and / or state or function transition request received from the UE10 and / or the state of the target cell 12 and / or its own state. Specifically, this will be discussed in detail later. Figure 4 A detailed description will be provided in the following section.

[0078] Figure 3 This is a further illustration of a method flowchart for a mobility handover method according to an embodiment of the present disclosure. For example... Figure 3 As shown, the mobility handover method applied to terminal devices may include at least the following steps.

[0079] In step S301, a first message sent by the first network device is received. This first message instructs the terminal device to perform a state or function transition, indicating that the terminal device is in a power-saving state or has its power-saving function enabled. This step can be understood as the opposite action to step S201 described above. Similarly, specifically... Figure 4 A detailed description will be provided in the following section.

[0080] Figure 4 This is an overall flowchart illustrating a mobility handover method according to an embodiment of the present disclosure. Figure 4 As shown, the mobility handover method in this embodiment of the disclosure involves at least: a terminal device (e.g., UE10), a first network device (e.g., serving cell 11 or serving base station 11), and a second network device (e.g., target cell 12 or target base station 12). The specific process is as follows:

[0081] S4-0, The terminal device sends a first measurement result to the first network device, wherein the first measurement result is generated based on the first signal measurement.

[0082] In one embodiment of this disclosure, the first signal may be a low-power signal.

[0083] As mentioned above, UE10 is in power-saving mode or has power-saving function enabled at this time, and cannot interact through high-power signals. It can perform measurements based on low-power signals and generate the corresponding first measurement result.

[0084] Furthermore, the first measurement result may include, but is not limited to, relevant indicators such as signal strength (e.g., reference signal received power (RSRP)), signal quality (e.g., reference signal received quality (RSRQ), signal-to-interference-plus-noise ratio (SINR)), and cell load of the serving cell 11 and / or neighboring cells (e.g., target cell 12), and this disclosure does not limit the specific details; the first measurement result may be a measurement report, etc., and this disclosure does not limit the specific form.

[0085] S4-1. The terminal device sends a status or function transition request to the first network device. Specifically, UE10 may send a status or function transition request to the serving cell 11 based on the first measurement result and / or a preset threshold, wherein the preset threshold can be understood as a threshold value.

[0086] In one embodiment of this disclosure, the preset threshold can be understood as a threshold value for a certain indicator (e.g., RSRP) in the above measurement. When the measured value of the indicator in the first measurement result received in step S4-0 is less than the threshold value, UE10 sends the state or function transition request to serving cell 11.

[0087] In another embodiment of this disclosure, the preset threshold can be understood as a time limit. When the duration of UE10 in power-saving mode or with power-saving function enabled reaches a certain threshold, UE10 sends a state or function switching request to serving cell 11.

[0088] It is worth noting that when UE10 is in power-saving mode or the duration of power-saving function is enabled reaches a certain threshold, UE10 may send a notification and / or indication to serving cell 11 instead of a request message. In other words, when the duration reaches a certain threshold, UE can switch to connected mode on its own, but it needs to notify and / or indicate to serving cell 11 in order to synchronize its state with the network.

[0089] It should be noted that step S4-1 is an optional step, as described in step S4-2.

[0090] S4-2. The first network device sends a first message to the terminal device, wherein the first message is used to instruct the terminal device to perform a state or function switch, and the terminal device is in energy-saving state or has the energy-saving function enabled.

[0091] As described above, step S4-1 is an optional step. That is, the prerequisite for serving cell 11 to send the first message to UE 10 can be receiving the aforementioned state or function transition request, an instruction from UE 10, or the obtained state of target cell 12 and / or the state of serving cell 11 itself. Based on the aforementioned first measurement result and / or request and / or instruction and / or the state of target cell 12 and / or the state of serving cell 11 itself, serving cell 11 makes a state transition decision and then sends the first message to UE 10, notifying it to perform a state or function transition.

[0092] In one embodiment of this disclosure, the state of the target cell 12 may be whether it supports an energy-saving mechanism or an energy-saving state, and / or whether it is in an energy-saving state or has its energy-saving function enabled; the state of the serving cell 11 itself may be whether it has enabled or disabled its energy-saving mechanism, and / or whether it expects to enable or disable its energy-saving mechanism.

[0093] S4-3. The terminal device sends a second message to the first network device, wherein the second message is used to confirm the state or function transition.

[0094] In other words, UE10 can perform a feedback handshake with serving cell 11 to confirm that a state transition or function switch has been performed. The feedback information (i.e., the second message) may include at least one of the following: Radio Resource Control (RRC) message, Media Access Control (MAC) CE message, signals and / or sequences for energy saving purposes, and information indicating feedback from the first network device (e.g., feedback based on a certain signal indicated by the network; for example, the feedback type indication of UE10 may be carried in the aforementioned first message, and UE10 will provide feedback based on this indication).

[0095] It should be noted that step S4-3 is an optional step.

[0096] S4-4. The terminal device sends a second measurement result to the first network device, wherein the second measurement result is generated based on the second signal measurement.

[0097] In one embodiment of this disclosure, the second signal may be a high-power signal.

[0098] As described above, UE10 has switched to the connected state (either based on the feedback handshake in S4-3 or after the default duration). At this time, UE10 can perform measurements based on the high-power signal and generate the corresponding second measurement result. Similar to the first measurement result, this disclosure does not limit the indicators included in the second measurement result; nor does it limit the specific form of the second measurement result.

[0099] In one embodiment of this disclosure, the second measurement result may be measured and reported by UE10 after receiving the first message and completing the conversion. That is, the first message may be a new condition that triggers UE10 to perform measurement and report based on the high-power signal. The measurement-related configuration of the high-power signal may be pre-configured to UE10 by the network, or it may be carried in the first message.

[0100] It should be noted that step S4-4 is an optional step.

[0101] S4-5. The first network device sends a third message to the second network device, wherein the third message is used to request mobility handover.

[0102] Specifically, after UE10 transitions to the connected state, the serving cell 11 sends a third message to the target cell 12 to request mobility handover. The serving cell 11 may decide to send a handover request (i.e., the third message) to the target cell 12 to access the target cell 12 based on a first measurement result provided by low-power signal measurement before the UE10 state transition (i.e., in power-saving mode or with power-saving function enabled) and / or a second measurement result provided by high-power signal measurement after the UE10 state transition (i.e., in connected mode).

[0103] S4-6, The second network device sends a handover request confirmation to the first network device.

[0104] In S4-7 to S4-8, the serving cell 11 sends an RRC reconfiguration to UE10 to instruct it to perform a handover. UE10 performs the handover and sends an RRC reconfiguration completion message to the target cell 12.

[0105] Optionally, after UE10 completes the handover and accesses the target cell 12, the target cell can enable energy-saving functions for UE10 to reduce energy consumption.

[0106] This concludes the description of the entire process for pre-transitioning UEs in energy-saving mode or with energy-saving functions enabled, as proposed in this disclosure, to reduce transmission performance loss due to mobility. However, this method, because it requires the UE to return to connected mode, may increase UE power consumption. As mentioned above, energy saving is an important consideration in the design of future communication systems. The following will combine... Figures 5-7This section introduces another method that allows for mobility switching even with significant energy savings.

[0107] Figure 5 This is a further illustration of a method flowchart for a mobility handover method according to an embodiment of the present disclosure. For example... Figure 5 As shown, the mobility handover method applied to the first network device may include at least the following steps.

[0108] In step S501, a fourth message is sent to the terminal device, wherein the fourth message includes power-saving configuration information of at least one third network device. As described above, this figure will introduce a more energy-efficient method. Specifically, a method of providing configuration in advance can be proposed, allowing UE10 to remain in and / or switch to power-saving mode, and achieving mobility handover through low-power signal interaction. This method of providing configuration in advance can involve the serving cell 11 sending a fourth message to UE10, which includes power-saving configuration information of one or more candidate cells 13. Depending on the handover method, the power-saving configuration information may include at least one of the following: configuration information of the target cell 12, conditional handover configuration information in power-saving mode, mobility handover configuration information triggered by Layer 1 / Layer 2 in power-saving mode, network-triggered mobility handover configuration information, etc. Specifically, this will be combined with... Figure 7 Please provide a more detailed description.

[0109] Figure 6 This is a further illustration of a method flowchart for a mobility handover method according to an embodiment of the present disclosure. For example... Figure 6 As shown, the mobility handover method applied to terminal devices may include at least the following steps.

[0110] In step S601, a fourth message sent by the first network device is received, wherein the fourth message includes energy-saving configuration information of at least one third network device. This step can be understood as the opposite action to step S501 above. Similarly, specifically... Figure 7 A detailed description will be provided in the following section.

[0111] Figure 7 This is a further illustration of the overall flowchart of the mobility handover method according to an embodiment of the present disclosure. For example... Figure 7 As shown, the mobility handover method in this embodiment of the present disclosure may include at least: a terminal device (e.g., UE10), a first network device (e.g., serving cell 11 or serving base station 11), and a third network device (e.g., candidate cell 13 or candidate base station 13, specifically as follows). Figure 7 The candidate cells shown are 13-1...13-n, i.e., n candidate cells 13). The specific process is as follows:

[0112] S7-0, The terminal device sends the measurement result to the first network device, wherein the measurement result is generated based on the measurement of the first signal and / or the second signal, and the terminal device may be in power-saving mode or have power-saving function enabled, or be in connected mode.

[0113] Specifically, UE10 performs measurements based on network configuration. Since UE10 can be in either power-saving or connected mode, the measurement can be based on a high-power signal (i.e., the second signal) and / or a low-power signal (i.e., the first signal). The specific signal that UE10 uses for measurement can be determined based on the network configuration.

[0114] In one embodiment of this disclosure, the configuration may be a time-domain or frequency-domain configuration for transmitting high-power or low-power signals, and / or conditions for measuring the corresponding signals. For example, measurement of the low-power signal may be initiated only if the high-power signals RSRP and / or RSRQ meet a certain threshold.

[0115] S7-1, The first network device determines the mobility handover decision.

[0116] In one embodiment of this disclosure, the mobility handover decision may be generated based on the measurement results in step S7-0.

[0117] S7-2, The first network device sends a third message to at least one third network device, wherein the third message is used to request mobility handover and includes power saving capability information of the terminal device.

[0118] Specifically, the third message may be a handover request, which the serving cell 11 may send to one or more of the candidate cells 13-1 to 13-n. The handover request may be implemented through existing handover commands and may additionally indicate the power-saving capability information of UE10 (e.g., the power-saving function or power-saving state capability of UE10).

[0119] S7-3. At least one third network device performs access control. Specifically, candidate cell 13, having received the aforementioned third message, will make an access control decision and may choose to accept or reject the handover request.

[0120] S7-4. At least one third network device sends a fifth message to the terminal device, wherein the fifth message includes energy-saving capability information and / or energy-saving configuration information of the third network device.

[0121] The fifth message can be a handover request confirmation. Specifically, after at least one candidate cell 13 selects to accept the handover request in step S7-3, it sends a handover request confirmation to the serving cell 11. This confirmation may include the candidate cell 13's own energy-saving capability information (e.g., support for energy-saving mode or energy-saving function) and / or energy-saving configuration information (e.g., configuration of energy-saving mode).

[0122] S7-5. The first network device sends a fourth message to the terminal device, wherein the fourth message includes power-saving configuration information of at least one third network device. The fourth message can be understood as mobility configuration. As mentioned above, since UE10 can be in both power-saving and connected states, the power-saving configuration information configured by the serving cell 11 for UE10 will differ depending on the state of UE10, as follows:

[0123] (1) When the terminal device is in power saving mode or the power saving function is enabled, the first network device sends at least one fourth message to the terminal device based on the first signal, wherein the fourth message includes power saving configuration information of a third network device or a second network device, wherein the fourth message sent based on the first signal includes: a low power sequence.

[0124] Specifically, as described above, the technical effect this disclosure aims to achieve is to complete the entire mobility handover process under deep energy saving conditions. Therefore, when UE10 is in energy-saving mode or has energy-saving function enabled, the network needs to perform configuration based on the low-power signal (i.e., the first signal) while it remains in energy-saving mode or with energy-saving function enabled, that is, to send the fourth message based on the low-power signal. Furthermore, since the number of bits carried by the low-power signal is limited, a single fourth message can only carry information about one candidate cell 13 or target cell 12. If there are multiple candidate cells 13, multiple fourth messages can be sent based on the low-power signal for configuration.

[0125] Furthermore, since the number of bits carrying information in a low-power signal is limited, once it contains the identifier ID of a candidate cell 13 or a target cell 12, other information may not be fully contained within the low-power signal. To address this, other information can be carried based on a predefined index.

[0126] In one embodiment of this disclosure, the fourth message can be a low-power (LP) sequence. Taking a 10-bit LP sequence as an example: the first 5 bits can be the ID of target cell 12 or candidate cell 13; the 5th and 6th bits can be the execution condition type (e.g., the execution condition is an LP measurement event, 00 can represent an LP-A3 event, 01 can represent an LP-A5 event, etc.); the following 3 bits represent the threshold corresponding to the event. For example, if the network is configured with 8 threshold values, the corresponding threshold can be represented by 3 binary bits.

[0127] Furthermore, the fourth message can be a cell change instruction. Since UE10 is already in power-saving mode, the instruction is an LP sequence, which directly carries the information of UE10's target cell 12 and may indicate the necessary information for access via LP signal.

[0128] (2) When the terminal device is in a connected state, the first network device sends at least one fourth message to the terminal device based on the first signal and / or the second signal, wherein the fourth message includes energy-saving configuration information and / or status or function switching indication of the third network device.

[0129] As mentioned above, when UE10 is in connected state, the network can be configured based on either a low-power signal (i.e., the first signal) or a high-power signal (i.e., the second signal). The candidate cells in the energy-saving configuration information based on these two configurations can be the same or different. This can be further subdivided as follows:

[0130] a) When the terminal device is in a connected state, and the first network device sends at least one fourth message to the terminal device based on the second signal, wherein the fourth message includes power-saving configuration information of the third network device. That is, the serving cell 11 sends a fourth message to UE 10 based on a high-power signal, wherein the fourth message may include information of one or more candidate cells 13.

[0131] It should be noted that high-power signals carry a lot of information, so the information of multiple candidate cells 13 can all be carried in a single fourth message.

[0132] b) When the terminal device is in a connected state, and the first network device sends at least one fourth message to the terminal device based on the first signal, wherein the fourth message includes power-saving configuration information and / or status and function transition indication of the third network device. That is, the serving cell 11 sends one or more fourth messages to the UE 10 based on the low-power signal, wherein one fourth message may include information of a candidate cell 13.

[0133] At this time, UE10 can directly perform execution or measurement based on the energy-saving configuration information; or, in order to save more energy, it can first switch to the energy-saving state based on the state and function conversion indication carried in the fourth message, and then perform execution or measurement based on the energy-saving configuration information.

[0134] Furthermore, in this scenario, when the fourth message only includes the energy-saving configuration information of the third network device corresponding to the first signal, that is, when it does not include the state and function transition indication, the serving network 11 can also send the first message to the UE10 separately, wherein the first message is used to instruct the UE10 to perform a state or function transition (i.e., steps S7-7 to S7-8).

[0135] c) When the terminal device is in a connected state, and the first network device sends at least one fourth message to the terminal device based on the first signal and the second signal, wherein the fourth message includes power-saving configuration information and / or status or function transition indication of the third network device. That is, the serving cell 11 sends a fourth message to UE10 based on high-power signals and low-power information. Similar to step S7-1, the fourth message may also include conditions for measuring the corresponding signals, such as enabling the measurement of low-power signals only when the high-power signals RSRP and / or RSRQ meet a certain threshold value.

[0136] It should be noted that (1) is more applicable to scenarios within the same control unit / base station (intra-CU / gNB), where the UE does not need to perform security key updating and may not need to change the Layer 2 protocol stack. Therefore, it can be configured through low-power signal indication without connection state. (2) can be applied to scenarios between different control units / base stations (intra-CU / gNB) and / or inter-CU / gNB, providing more complete configuration.

[0137] S7-6. The terminal device sends a configuration confirmation message to the first network device.

[0138] S7-7. When the terminal device is in a connected state and the fourth message only includes the energy-saving configuration information of the third network device corresponding to the first signal, the first network device sends a first message to the terminal device, wherein the first message is used to instruct the terminal device to perform a state or function transition.

[0139] It should be noted that this step is optional.

[0140] S7-8. The terminal device sends a state transition confirmation message to the first network device.

[0141] The aforementioned energy-saving configuration information may include at least one or more of the following: configuration information of the second network device; conditional handover configuration information in energy-saving mode; mobility handover configuration information triggered by Layer 1 / Layer 2 in energy-saving mode; and network-triggered mobility handover configuration information. These will be described in detail below:

[0142] Scenario 1: When the energy-saving configuration information is the configuration information of the second network device:

[0143] S7-9. The terminal device performs mobility handover. As described above (1), the fourth message can be a cell change instruction. In this step, UE10 performs mobility handover directly based on this cell change instruction and accesses candidate cell 13.

[0144] Scenario 2: When the energy-saving configuration information is the conditional switching configuration information for energy-saving mode:

[0145] S7-10. The terminal device performs mobility handover based on the third measurement result of the first signal and preset conditions. That is, when the configuration information is in energy-saving CHO mode, UE10 will perform measurements based on low-power signals, generate a third measurement result, and when it meets the preset conditions in CHO, perform mobility handover and access candidate cell 13.

[0146] Scenario 3: When the energy-saving configuration information is energy-saving Layer 1 / Layer 2 triggered mobility handover configuration information and / or network triggered mobility handover configuration information:

[0147] S7-11. The terminal device sends a fourth measurement result based on the first signal to the first network device. That is, if the network configures UE10 with energy-saving LTM or network-triggered mobility (cell change), UE10 will perform measurements based on the low-power signal and report them to the network (i.e., the fourth measurement result). The fourth measurement result may be a cell index or configuration index that meets the mobility conditions, and / or the corresponding measurement report.

[0148] S7-12~S7-13, the first network device sends a mobility handover indication and / or a state or function transition indication to the terminal device based on the first signal. That is, the network will issue a cell change command (i.e., mobility handover indication) to UE10 based on a low-power signal. This command can be implemented through a low-power sequence, which at least contains the configuration index corresponding to the target cell 12. UE10 will synchronize based on the low-power signal synchronization sequence of the corresponding cell, perform mobility handover, and access the target cell 12.

[0149] It should be noted that the state of UE10 in target cell 12 is related to the configuration provided by target cell 12. If target cell 12 provides an energy-saving state configuration, then terminal 10 will remain in the energy-saving state after performing mobility and will not need to enter the connected state. Otherwise, UE10 needs to enter the connected state.

[0150] This concludes the description of the entire process of providing pre-configuration for the UE, enabling the UE to remain in and / or switch to an energy-saving state, and achieving mobility handover through low-power signal interaction. This approach can avoid increased power consumption, ensure that the UE has the most suitable serving cell, and simultaneously guarantee UE performance, achieving mobility handover for the UE and / or the network under deep energy-saving conditions.
