Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method, device, storage medium, and computer program product. Background Technology

[0002] With the rapid development of communication technology, while people enjoy the convenience brought by wireless communication devices, the impact of electromagnetic radiation generated by these devices on human health is increasingly attracting attention. Government departments and telecommunications regulatory agencies in various countries require that electromagnetic radiation to the human body be reduced to a safe level. For example, the U.S. Federal Communications Commission (FCC) stipulates the maximum permissible exposure (MPE) for electromagnetic radiation. The MPE safety value is set so that, under any exposure conditions, the corresponding specific absorption rate (SAR) value must not exceed the limit.

[0003] Terminal devices will report measurement reports of their serving cell and neighboring cells under specific triggering conditions. Network devices will use these measurement reports to determine the terminal device's mobility-related behaviors, such as handover. However, if the terminal device meets the MPE (Multi-Level Protection) constraints, its capabilities will be limited, such as reducing transmit power or even shutting down the transmit beam. This may cause the terminal device to send a preamble and / or MSG3, which could lead to the target base station failing to demodulate the random access messages, thus resulting in handover failure. Summary of the Invention

[0004] This application discloses a communication method, apparatus, storage medium, and computer program product that can reduce the impact of MPE on mobility and improve the success rate of handover.

[0005] In a first aspect, embodiments of this application disclose a first communication method applied to a terminal device. This communication method includes: in response to the terminal device being affected by the Maximum Allowable Radiation Level (MPE), recording radiation impact information caused by the MPE; receiving a first RRC reconfiguration message from a source base station; recording a measurement report from the terminal device; and sending the measurement report and radiation impact information to the source base station. Thus, the source base station can perform handover processing based on the radiation impact information, which can reduce the impact of MPE on mobility and improve the handover success rate.

[0006] In one possible example, before recording the radiation impact information of the terminal device, the communication method further includes: receiving, or obtaining from a preset protocol, indication information, which indicates that under the influence of MPE, if a first RRC reconfiguration message is received from the source base station, it is permissible to report the terminal device's measurement report and radiation impact information caused by MPE; and sending the measurement report and radiation impact information to the source base station, including: sending the measurement report and radiation impact information to the source base station based on the indication information. In this way, the terminal device can upload radiation impact information caused by MPE when a measurement report needs to be reported, based on the indication information, which helps reduce the impact of MPE on mobility and improves the handover success rate.

[0007] In one possible example, the indication information is specifically used to instruct the addition of radiation impact information to the measurement report of the terminal device; sending the measurement report and radiation impact information to the source base station includes: sending the measurement report with the added radiation impact information to the source base station based on the indication information. In this way, the terminal device can add radiation impact information caused by MPE to the measurement report based on the indication information and upload the measurement report with the added radiation impact information. This avoids receiving radiation impact information after the measurement report, which could lead to a handover failure event caused by the second RRC reconfiguration message sent to the terminal device not being optimized based on the radiation impact information.

[0008] In one possible example, the indication message could be used to indicate that measurement reports should not be reported when the terminal device is affected by MPE. Thus, after receiving the first RRC reconfiguration message from the source base station, no measurement report will be sent to the source base station, the handover process will not be triggered, and handover failure can be avoided.

[0009] In one possible example, the instruction message may indicate that measurement reports are permitted when the terminal device is not affected by the MPE. Thus, since the terminal device is not affected by the MPE, the handover process for the terminal device will not be impacted.

[0010] In one possible example, after sending the measurement report and radiation impact information to the source base station, the communication method further includes receiving a second RRC reconfiguration message corresponding to the radiation impact information from the target base station. This second RRC reconfiguration message can be understood as an optimized RRC reconfiguration message based on the radiation impact information. Thus, random access can be initiated to the target base station based on the second RRC reconfiguration message to reduce the impact of MPE (Mean Differential Equivalence).

[0011] In one possible example, the communication method further includes initiating random access to the target base station based on a second RRC reconfiguration message or radiation impact information. In this way, the uplink beam transmitting random parameters during the random access process can be unaffected by MPE, reducing the impact of MPE on random access and improving the handover success rate.

[0012] Secondly, embodiments of this application disclose a second communication method applied to a terminal device. This communication method includes: receiving indication information from the network side, or obtaining indication information from a preset protocol. The indication information is used to indicate unrestricted objects and / or objects to be restricted in the MPE (Multi-Level Processing) mechanism. Unrestricted objects include at least one of the following: unrestricted channels, unrestricted signaling bearers, unrestricted scenarios, unrestricted channels corresponding to unrestricted purposes, unrestricted time periods after the identification of an unrestricted scenario, and unrestricted processes within an unrestricted scenario. In response to the terminal device meeting the MPE's restrictive conditions, the object to be restricted is processed based on the indication information, so that the terminal device is affected by the MPE. Thus, the object to be restricted can be processed based on the indication information, reducing the impact of MPE on mobility and improving the success rate of handover.

[0013] Thirdly, this application discloses a third communication method applied to a source base station. This communication method includes: sending a first RRC reconfiguration message to a terminal device; and receiving a measurement report and radiation impact information from the terminal device, wherein the radiation impact information is information generated by the MPE affecting the terminal device. Thus, the source base station can perform handover processing based on this radiation impact information, reducing the impact of MPE on mobility and improving the handover success rate.

[0014] In one possible example, receiving a measurement report and radiation impact information from the terminal device includes receiving a measurement report with added radiation impact information from the terminal device. In this way, the terminal device can add and upload radiation impact information caused by MPE (Mean Effects Per Element) to the measurement report based on indication information. This avoids receiving radiation impact information after the measurement report, which could lead to a handover failure event caused by the second RRC reconfiguration message sent to the terminal device not being optimized based on the radiation impact information.

[0015] In one possible example, after receiving the measurement report and radiation impact information from the terminal device, the communication method further includes sending the radiation impact information to the target base station. Thus, the target base station can perform handover processing based on this radiation impact information, reducing the impact of MPE on mobility and improving the handover success rate.

[0016] In one possible example, before sending radiation impact information to the target base station, the communication method further includes determining the target base station based on the radiation impact information. This reduces the impact of MPE on mobility and improves the success rate of handover.

[0017] In one possible example, after sending radiation impact information to the target base station, the communication method further includes receiving a handover request rejection message from the target base station. Thus, a handover procedure is not performed, thereby avoiding handover failure.

[0018] In one possible example, after sending radiation impact information to the target base station, the communication method further includes: receiving a second RRC reconfiguration message corresponding to the radiation impact information from the target base station; and sending the second RRC reconfiguration message to the terminal device. Thus, the terminal device can initiate random access to the target base station based on the second RRC reconfiguration message to reduce the impact of MPE.

[0019] Fourthly, this application discloses a fourth communication method applied to a source base station. This communication method includes: sending indication information to a terminal device. The indication information is used to indicate unrestricted objects and / or objects to be restricted in the MPE (Mobile Policy Environment). The unrestricted objects include at least one of the following: unrestricted channels, unrestricted signaling bearers, unrestricted scenarios, unrestricted channels corresponding to unrestricted purposes, unrestricted time periods after the unrestricted scenario is identified, and / or unrestricted procedures within the unrestricted scenario. Thus, the terminal device can process the objects to be restricted based on the indication information, which can reduce the impact of MPE on mobility and improve the success rate of handover.

[0020] In one possible example, the communication method further includes identifying that the terminal device is in an unrestricted environment before sending the instruction information to the terminal device. This improves the effectiveness of the instruction.

[0021] Fifthly, this application discloses a fifth communication method applied to a target base station. This communication method includes: receiving a measurement report and radiation impact information from a source base station, wherein the radiation impact information is information generated by the MPE (Mean Effect of Power) affecting the terminal device. Thus, the target base station can perform handover processing based on this radiation impact information, reducing the impact of MPE on mobility and improving the handover success rate.

[0022] In one possible example, after receiving the measurement report and radiation impact information from the source base station, the communication method further includes sending a handover request rejection message to the source base station. Thus, handover failure can be avoided by not performing a handover procedure.

[0023] In one possible example, after receiving the measurement report and radiation impact information from the source base station, the communication method further includes sending a second RRC reconfiguration message corresponding to the radiation impact information to the source base station. Thus, the terminal device can initiate random access to the target base station based on the second RRC reconfiguration message to reduce the impact of MPE.

[0024] In one possible example, the communication method further includes receiving a random access request initiated by the terminal device based on a second RRC reconfiguration message or radiation impact information. This reduces the impact of MPE during random access and helps improve the handover success rate.

It is understood that access network equipment can be a CU node, a DU node, or a device including both CU and DU nodes. Furthermore, the CU can be classified as an access network device within the access network RAN, or as an access network device within the core network CN; no restrictions are placed here.

[0084] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0085] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application are described below with reference to the accompanying drawings. Please refer to... Figure 1 , Figure 1This is a schematic diagram of the structure of a communication system provided in an embodiment of this application. For example... Figure 1 As shown, the communication system may include terminal device 100, source base station 200, and target base station 300. This application embodiment does not limit the names of terminal device 100, source base station 200, and target base station 300. For example, a base station may also be called a network device. A source base station may also be called a source network device, and a target base station may also be called a target network device.

[0086] This application embodiment does not limit the number of terminal device 100, source base station 200, and target base station 300. Source base station 200 and target base station 300 each have a certain coverage area. The coverage areas of source base station 200 and target base station 300 may overlap. The wireless coverage area of ​​source base station 200 and target base station 300 may include one or more cells. Terminal device 100 within the cell coverage area communicates with source base station 200 and target base station 300 through the cell's transmission resources (e.g., frequency domain resources, spectrum resources, or time-frequency resources). The cell can be a macro cell or a small cell. Optionally, a small cell may include: metro cell, micro cell, pico cell, or femto cell, etc. This application embodiment does not limit the specific technology and equipment form used by source base station 200 and target base station 300.

[0087] Terminal devices located within the coverage area of ​​source base station 200 can communicate with source base station 200 wirelessly. Terminal devices located within the coverage area of ​​target base station 300 can communicate with target base station 300 wirelessly. Terminal devices located in overlapping areas can communicate wirelessly with both source base station 200 and target base station 300. Taking the communication between source base station 200 and terminal device 100 as an example, when source base station 200 acts as the sender, it can send downlink information to terminal device 100. Correspondingly, when terminal device 100 acts as the receiver, it can receive downlink information from source base station 200. When terminal device 100 acts as the sender, it can send uplink information to source base station 200. Correspondingly, when source base station 200 acts as the receiver, it can receive uplink information from terminal device 100. Terminal device 100 can be fixed or movable.

[0088] It should be noted that, Figure 1 The communication system shown is one implementation of an embodiment of this application. In practical applications, the communication system and the devices within it may include more or fewer components, which is not limited here. Optionally, the communication system may also include other devices. For example, the communication system may also include core network equipment (…). Figure 1 (Not shown). The source base station 200 and the target base station 300 can be connected to the core network equipment wirelessly or via wired means. The core network equipment and the source base station 200 and target base station 300 can be independent and different physical devices, or the functions of the core network equipment can be integrated with the functions of the source base station 200 and target base station 300 on the same physical device, or a single physical device can integrate some functions of the core network equipment and some functions of the source base station 200 and target base station 300. For example, the communication system may also include wireless relay equipment or wireless backhaul equipment (…). Figure 1 (Not shown).

[0089] To facilitate understanding of the embodiments of this application, some terms involved in the embodiments of this application will be explained below.

[0090] (1) Maximum permissible exposure (MPE) refers to the maximum level of radio frequency radiation that a human body is allowed to be exposed to without harm. This permissible value can be expressed as the electromagnetic field quantity or power density (PD). The MPE safety value is set so that, under any exposure conditions, the corresponding specific absorption rate (SAR) value must not exceed the limit.

[0091] Regulatory bodies such as the Federal Communications Commission (FCC), the International Commission on Non-Ionizing Radiation Protection (ICNIRP), the European Union (CE) certification body, and Nippon Telegraph & Telephone (NTT) regulate or limit MPE (Mean Power Exposure). MPE limits are typically imposed on wireless devices communicating above 6 GHz. Because higher frequencies above 6 GHz interact with the surface of human skin, MPE limits are regulatory measures of area-based exposure. For example, for millimeter-wave systems, the MPE limit is 1 mW / cm², meaning the power density experienced by the human body cannot exceed 1 mW / cm². As another example, for millimeter-wave systems, the MPE limit is 20 mW / cm², meaning the power density experienced by the human body cannot exceed 20 mW / cm².

[0092] (2) The theoretical hazard zone (NHZ) is an area determined based on beam transmit angle, transmit power, and beam diameter. Within this zone, the transmit power of the terminal equipment exceeds the requirements of the MPE (Mean Power Registry). For an example using a multi-antenna UE, please refer to [link to relevant documentation]. Figure 2 , Figure 2 This is a diagram illustrating the relationship between MPE and NHZ, provided as an embodiment of this application. Figure 2 As shown, the UE can transmit multiple beams. Based on the beam transmission angle, transmission power and beam diameter, regions 1 and 2 can be NH Hz, and the radiation E in regions 1 and 2 is greater than MPE.

[0093] (3) The MPE constraint is used to determine whether the terminal device is affected by the MPE, i.e., whether to perform an operation that restricts the capabilities of the terminal device. For example, if the terminal device meets the MPE constraint, it is determined that the terminal device is affected by the MPE. Otherwise, it is not affected by the MPE. The MPE constraint that the terminal device meets may include the terminal device detecting a person in the NHZ; or the terminal device detecting a person in the NHZ and the person's duration in the NHZ exceeds a certain threshold; or the terminal device detecting a SAR value in the NHZ and the SAR value exceeds a certain threshold, etc., which are not limited here.

[0094] In one possible example, the capability limitation operation of the terminal device due to MPE is triggered when a person is detected in the NHZ. Alternatively, the capability limitation operation can be triggered only when the time a person stays in the NHZ exceeds a certain threshold. This limitation operation may include reducing the transmit power (or uplink power) of all beams, reducing the uplink power of the beam in the direction of the person, shutting down the transmit beam, or shutting down the transmit beam in the direction of the person, etc.

[0095] If no one is in the NHZ of the terminal equipment, the uplink power of the previously reduced beam can be restored.

[0096] (4) The preamble is the actual content sent by the terminal device in the physical random access channel. It consists of a cyclic prefix (CP) of length Tcp and a sequence of length Tseq.

[0097] (5) Message 3 (MSG3), which is the third message in the random access procedure, is used to distinguish different terminal device states and application scenarios.

[0098] The following describes the process of the existing switching method. Please refer to [link / reference]. Figure 3This is a flowchart illustrating a switching method provided by existing technology. For example... Figure 3 As shown, the entities involved in the handover include the terminal device, the source base station, and the target base station. The handover methods may include:

[0099] S301. The source base station sends the first RRC reconfiguration message to the terminal device.

[0100] Accordingly, the terminal device receives the first RRC reconfiguration message from the source base station.

[0101] The terminal device is currently within the coverage area of ​​the source cell of the source base station and is in a connected state. The terminal device can perform signal measurement based on the first RRC reconfiguration message. Optionally, the first RRC reconfiguration message may include, but is not limited to, parameters such as the measurement object, report configuration, and measurement identifier.

[0102] S302. The terminal device sends a measurement report to the source base station.

[0103] Correspondingly, the source base station receives measurement reports from the terminal equipment.

[0104] The terminal device, after measuring the cell according to the first RRC reconfiguration message, can generate a measurement report. This cell can be the cell indicated in the first RRC reconfiguration message or a cell determined according to the first RRC reconfiguration message. For example, it could be a co-frequency neighboring cell or an inter-frequency neighboring cell of the source cell currently accessed by the terminal device. The terminal device can report various events to the source base station through the measurement report. This application does not limit the timing of the terminal device reporting the measurement report. For example, when the signal strength of the source cell currently accessed by the terminal device is lower than a first threshold and the signal strength of the target cell is higher than a second threshold, the terminal device sends a measurement report to the source base station. The specific determination of the first and second thresholds is not limited.

[0105] S303. The source base station makes a handover decision to determine whether the terminal equipment needs to be handed over.

[0106] Specifically, after receiving the measurement report reported by the terminal device, the source base station determines whether the terminal device needs to be handed over based on the measurement report. If it is determined that the terminal device needs to be handed over, then proceed to step S304.

[0107] S304. The source base station sends a handover request message to the target base station.

[0108] Accordingly, the target base station receives a handover request message from the source base station.

[0109] S305. The target base station performs admission control.

[0110] Specifically, the target base station determines whether to allow the terminal device to access the network based on its own connection count and other factors. If the terminal device is allowed to access the network, then S306 is executed.

[0111] S306. The target base station sends a handover request ACK message to the source base station.

[0112] Correspondingly, the source base station receives the handover request confirmation message from the target base station.

[0113] Optionally, the handover request confirmation message may include, but is not limited to, parameters such as the new cell radio network temporary identity (C-RNTI) and the target base station security algorithm.

[0114] S307. The source base station sends a second RRC reconfiguration message to the terminal device.

[0115] Accordingly, the terminal device receives the second RRC reconfiguration message from the source base station.

[0116] In this step, the second RRC reconfiguration message can also be called a handover command message. This second RRC reconfiguration message may include all or part of the content from the handover request confirmation message in S306. Optionally, the second RRC reconfiguration message may include, but is not limited to, new C-RNTI, target base station security algorithm, and other parameters.

[0117] The source base station does not read the second RRC reconfiguration message and forwards it directly to the terminal device. Specifically, the handover command in the NR system contains relevant information about the target cell and the relevant configuration parameters required for the UE to access the target cell. For example, the handover command contains information about the target cell (such as the physical cell identifier (PCI) of the target cell and the frequency information corresponding to the target cell (such as the frequency point corresponding to the target cell), the C-RNTI allocated by the target cell to the terminal device, and the random access channel (RACH) resource information required for the terminal device to randomly access the target base station.

[0118] S308. The terminal device initiates random access to the target base station.

[0119] In the existing handover process, the terminal device will disconnect from the source base station, and there will be a brief interruption in the transmission and reception of data by the terminal device before it successfully connects to the target base station.

[0120] S309. The terminal device sends an RRC reconfiguration complete message to the target base station.

[0121] Specifically, after the terminal device accesses the target cell of the target base station, the terminal device sends an RRC reconfiguration complete message to the target base station, thereby completing the handover from the source base station to the target base station.

[0122] The handover preparation period is the time before the source base station sends a reconfiguration message to the terminal device, i.e., before step S306. The handover execution period is the time between the terminal device receiving the second RRC reconfiguration message and completing random access with the target base station, i.e., the handover completion period from steps S307 to S308 is after step S309.

[0123] like Figure 3 As shown, mobility management of connected terminal devices is controlled by network devices. Specifically, the network device instructs the terminal device which cell to hand over to and how to perform the handover by sending a handover message. Upon receiving the handover message, the terminal device accesses the target cell based on the information contained within it. Therefore, successful transmission of the handover message is a necessary condition for successful handover under traditional handover mechanisms.

[0124] However, if the terminal device meets the MPE constraints, it will limit the terminal device's capabilities, such as reducing the transmit power or even shutting down the transmit beam. This will cause the terminal device to send the preamble and / or MSG3, which may lead to the target base station failing to demodulate the random access message, thus resulting in handover failure.

[0125] Based on this, embodiments of this application propose a communication method, apparatus, storage medium, and computer program product that can reduce the impact of MPE on mobility and improve the success rate of handover.

[0126] Please see Figure 4 , Figure 4 This is a flowchart illustrating the first communication method provided in this application embodiment. The method includes, but is not limited to, the following steps:

[0127] S401. In response to the influence of MPE on the terminal device, the terminal device records the radiation impact information caused by the influence of MPE.

[0128] As mentioned earlier, the impact of MPE on terminal equipment refers to the terminal equipment meeting the MPE's limiting conditions and performing operations that restrict the terminal equipment's capabilities. For example, reducing the transmit power (or uplink power) of all beams, or reducing the uplink power of the beam in the direction of the person, or turning off the transmit beam, or turning off the transmit beam in the direction of the person, etc.

[0129] In this embodiment, the radiation impact information is information recorded when a terminal device is affected by MPE (Multi-Level Effect). This radiation impact information may include, but is not limited to, one or more of the following: uplink beam information, maximum uplink power, and uplink power margin. Uplink beam information may include whether each uplink beam is affected by MPE, the transmit power under MPE influence, or a reduction in transmit power. Maximum uplink power refers to the maximum transmit power when transmitting data or signaling under MPE influence. Uplink power margin refers to the remaining usable transmit power under MPE influence.

[0130] Radiation impact information can be recorded when it is determined that the terminal device is affected by MPE. For example, if the time when it is determined that the terminal device is affected by MPE is 18:00:00, then the radiation impact information is recorded at 18:00:00. The radiation impact information may also be recorded when a preset time has elapsed after the terminal device is affected by MPE, or when the uplink power adjusted after the terminal device is affected by MPE is less than a preset threshold, etc., and is not limited here.

[0131] The preset duration and preset threshold are not limited. For example, assuming a preset duration of 2 seconds, if the terminal device is determined to be affected by MPE at 18:00:00, then the radiation impact information is recorded at 18:00:02. Assuming a preset threshold of 20 watts, if the terminal device is determined to be affected by MPE at 18:00:00, and the uplink power of the uplink beam is 18 watts at 18:00:30, then the radiation impact information is recorded at 18:00:30.

[0132] In one possible example, step S400 may also be included before step S401. Figure 4 (Not shown in the image): Receives indication information from the network side or obtains it from a preset protocol.

[0133] Here, "network side" refers to network equipment, which may include the source base station currently accessed by the terminal device, or other network equipment, without limitation. If the network side is the source base station currently accessed by the terminal device, the indication information may be sent by the source base station to the terminal device in the first RRC reconfiguration message, or it may be sent to the terminal device separately, or it may be sent to the terminal device in other messages, etc., without limitation. The preset protocol can be a protocol pre-set by the operator or hardware developer, etc. It should be noted that if the indication information is sent by the source base station to the terminal device in the first RRC reconfiguration message, then step S403 can be executed after executing step S400. In the case of MPE, step S401 can be executed.

[0134] In this embodiment, the indication information may include first indication information. This first indication information is used to instruct the terminal device whether to report a measurement report when affected by MPE. For example, the first indication information indicates that the terminal device should not report a measurement report when affected by MPE. Thus, after receiving the first RRC reconfiguration message from the source base station, no measurement report will be sent to the source base station, and the handover process will not be triggered, thereby avoiding handover failure. On the other hand, when the terminal device is not affected by MPE, reporting a measurement report is allowed. Thus, after receiving the first RRC reconfiguration message from the source base station, it can communicate with... Figure 3 The process is the same as described above, sending a measurement report to the source base station. Since the terminal equipment is not affected by MPE, it will not affect the handover process of the terminal equipment.

[0135] The indication information may include second indication information. This second indication information instructs the terminal device whether to report a measurement report and MPE information when affected by MPE. For example, the second indication information instructs the terminal device to report its measurement report and radiation impact information caused by MPE when affected by MPE. Thus, after receiving the first RRC reconfiguration message from the source base station, the terminal device can send the measurement report and radiation impact information to the source base station. The source base station can determine not to perform a handover based on this radiation impact information to avoid handover failure. Alternatively, it can determine the target cell for handover based on the radiation impact information; for example, the target cell is a cell where the terminal device's beam is not affected by MPE. Alternatively, it can send this information to the target base station so that the target base station can optimize the second RRC configuration message based on the radiation impact information, thereby reducing the impact of MPE on mobility and improving the handover success rate.

[0136] This application does not limit the method for reporting radiation impact information. It can be reported separately to the source base station, or it can be reported together with the measurement report, or radiation impact information can be added to the measurement report before reporting to the source base station. Based on this, the indication information is used to indicate that if a first RRC reconfiguration message is received from the source base station when the terminal device is affected by MPE, then reporting the terminal device's measurement report and radiation impact information caused by MPE is permitted. Step S404 includes: sending the measurement report and radiation impact information to the source base station based on the indication information (or the second indication information).

[0137] Optionally, the indication information is specifically used to instruct the addition of radiation impact information to the measurement report; step S404 includes: sending the measurement report with added radiation impact information to the source base station based on the indication information (or the second indication information). In this way, radiation impact information can be added to the measurement report first, and then the measurement report with added radiation impact information can be sent to the source base station. This simultaneously sends both the measurement report without radiation impact information and the radiation impact information to the source base station, avoiding the occurrence of a handover failure event caused by receiving radiation impact information after the measurement report, which would result in the second RRC reconfiguration message sent to the terminal device not being optimized based on the radiation impact information.

[0138] For example, the second indication information allows the reporting of measurement reports when the terminal device is not affected by the MPE. Thus, after receiving the first RRC reconfiguration message from the source base station, a measurement report can be sent to the source base station. Since the terminal device is not affected by the MPE, the handover process of the terminal device will not be affected. In other words, when the terminal device is not affected by the MPE, the handover procedure is the same as in the prior art, and the aforementioned first and / or second indication information can be understood as invalid.

[0139] This application does not limit the method of sending the first and second instruction information mentioned above. They can be sent to the terminal device in advance, or they can be sent after the terminal device meets the MPE restriction conditions but before it is affected by the MPE. For example, if the first instruction information is used to instruct that a measurement report not be reported when the terminal device is affected by the MPE, the first instruction information can be sent after the terminal device meets the MPE restriction conditions but before it is affected by the MPE, without sending the second instruction information. As another example, if the first instruction information is used to instruct that a measurement report be reported when the terminal device is affected by the MPE, and the second instruction information is used to instruct that a measurement report with increased radiation impact information is allowed when the terminal device is affected by the MPE, then the first and second instruction information can be sent to the terminal device in advance.

[0140] S402, The source base station sends the first RRC reconfiguration message to the terminal device.

[0141] Accordingly, the terminal device receives the first RRC reconfiguration message from the source base station. Steps S402 and S403 can be referred to Figure 3 The description of step S302 will not be repeated here. It should be noted that when the terminal equipment is not affected by MPE, a measurement report for the terminal equipment can be recorded or reported. Alternatively, when the terminal equipment is affected by MPE, a measurement report for the terminal equipment may not be recorded or reported, or it may be reported together with the radiation impact information to the measurement report, or the measurement report and radiation impact information may be reported separately to the measurement report.

[0142] S403, Terminal equipment records measurement reports.

[0143] S404. The terminal equipment sends a measurement report and radiation impact information to the source base station.

[0144] exist Figure 4 In the described method, when a terminal device is affected by MPE (Mean Differential Effort), the radiation impact information caused by the MPE is recorded. If a first RRC (Reconfigurable Reconfiguration Code) message is received from the source base station, the terminal device first records a measurement report, and then sends the measurement report and radiation impact information to the source base station. In this way, the source base station can perform handover processing based on the radiation impact information, which can reduce the impact of MPE on mobility and improve the handover success rate.

[0145] Please see Figure 5 , Figure 5 This is a flowchart illustrating the second communication method provided in this application. The method includes, but is not limited to, the following steps:

[0146] S501. In response to the influence of MPE on the terminal device, the terminal device records the radiation impact information caused by the influence of MPE.

[0147] S502, The source base station sends the first RRC reconfiguration message to the terminal device.

[0148] S503, Terminal equipment records measurement reports.

[0149] S504. The terminal equipment sends a measurement report and radiation impact information to the source base station.

[0150] The steps S501 to S504 can be referred to the description of steps S401 to S404, and will not be repeated here.

[0151] It is understandable that after the source base station receives the measurement report and radiation impact information, it can refer to the description in step S303 to make a handover decision to determine whether the terminal device needs to handover. If so, a handover request message can be sent to the target base station. Otherwise, the handover process can be avoided by not triggering the handover procedure.

[0152] S505: The source base station sends radiation impact information to the target base station.

[0153] In this embodiment, the target base station can be a base station whose signal strength, as determined by the terminal device in the measurement report, is greater than that of the source base station. Alternatively, in one possible example, before step S505, the following step may be included: the source base station determines the target base station based on radiation impact information.

[0154] This application does not limit the method for determining the target base station. It can be based on whether the cell covered by the target base station is affected by MPE (Mean Transmission Effect). For example, a cell whose beam is not affected by MPE can be selected as the target cell, and then the target base station can be selected based on the base station corresponding to the target cell. This reduces the impact of MPE on mobility and improves the success rate of handover.

[0155] It should be noted that the radiation impact information sent in step S505 can be sent separately, or it can be carried in a handover request message or other messages and sent to the target base station, etc., without limitation here.

[0156] S506. The target base station sends a second RRC reconfiguration message corresponding to the radiation impact information to the terminal equipment through the source base station.

[0157] The second RRC reconfiguration message in step S506 can be understood as a message that optimizes the RRC reconfiguration message based on radiation impact information. In other words, the message in the second RRC reconfiguration message can be used to instruct the reduction of MPE effects. For example, it can instruct the terminal device not to use beams affected by MPE when transmitting random parameters. The random parameters may include preambles or MSG3, etc.

[0158] Before executing step S506, the target base station may perform the following: Figure 3 Step S305, as shown, performs access control to determine whether to allow the terminal device to access the system. The second RRC reconfiguration message in step S506 can be carried in the target base station's handover request confirmation message or other messages, or can be sent separately by the target base station to the source base station, etc., and is not limited here.

[0159] In one possible example, after step S506, the following step is also included: the target base station sends a handover request rejection message to the source base station. This avoids triggering the handover process and thus prevents handover failure.

[0160] S507. The terminal device initiates random access to the target base station based on the second RRC reconfiguration message or radiation impact information.

[0161] Step S507 can be referred to Figure 3 Regarding the description of step S308, it should be noted that in step S507, the uplink beam used for transmitting random parameters during the random access process may be unaffected by MPE. These random parameters may include preambles or MSG3, etc. It can be understood that using an uplink beam unaffected by MPE to transmit random parameters can reduce the impact of MPE on mobility and improve the handover success rate.

[0162] exist Figure 5 In the described method, when the terminal device is affected by MPE (Mean Differential Effort), radiation impact information caused by MPE is recorded. If a first RRC reconfiguration message is received from the source base station, the terminal device first records a measurement report, and then sends the measurement report and radiation impact information to the source base station. Then, the source base station sends the radiation impact information to the target base station, and the target base station can send a second RRC reconfiguration message corresponding to the radiation impact information to the source base station. The terminal device can then initiate random access to the target base station using either the second RRC reconfiguration message or the radiation impact information. In this way, the uplink beam transmitting random parameters during random access is unaffected by MPE, reducing the impact of MPE during random access and further improving the handover success rate.

[0163] Referring to step S309, in one possible example, after step S507, the following step may also be included: the terminal device sends an RRC reconfiguration complete message to the target base station.

[0164] Please see Figure 6 , Figure 6 This is a flowchart illustrating the third communication method provided in this application. The method includes, but is not limited to, the following steps:

[0165] S601. The terminal device receives instruction information from the network side or obtains it from a preset protocol.

[0166] The indication information in step S601 differs from the indication information in step S400. In this embodiment, the indication information is used to indicate unrestricted objects and / or objects to be restricted under the MPE (Mean Differential Process). Unrestricted objects can be objects unaffected by the MPE, while objects to be restricted can be objects affected by the MPE. That is, when the terminal device is affected by the MPE, unrestricted objects do not need to be adjusted based on the MPE requirements, while objects to be restricted do need to be adjusted based on the MPE requirements. Objects to be restricted can be objects other than unrestricted objects.

[0167] It should be noted that unrestricted objects can also be objects whose MPE impact is reduced. That is, when an object is identified as unrestricted, the MPE limitation on uplink power can be reduced, thereby reducing the impact of MPE. In the embodiments of this application, the unrestricted object can be determined as either an object unaffected by MPE or an object whose MPE impact is reduced, based on the scenario of the terminal device. For example, in an unrestricted scenario, the unrestricted object is determined to be an object unaffected by MPE, while in other scenarios, it is determined to be an object whose MPE impact is reduced. Alternatively, it can be determined based on the number of people in the NHZ area; for example, when the number of people is large, the unrestricted object is determined to be an object unaffected by MPE, while when the number of people is small, it is determined to be an object whose MPE impact is reduced, etc.

[0168] Unrestricted objects include, but are not limited to, at least one of the following: unrestricted channels, unrestricted signaling bearers, unrestricted scenarios, unrestricted channels corresponding to unrestricted purposes, unrestricted time periods after an unrestricted scenario is identified, and unrestricted processes within an unrestricted scenario.

[0169] Unrestricted channels refer to channels unaffected by MPE (Moving Power Expansion). These can include physical uplink control channels (PUCCH) or physical random access channels (PRACH). Signaling transmitted in unrestricted channels is mostly control signaling, while most of the radiation comes from data packet signaling. Therefore, it is possible to pre-determine that unrestricted channels are unaffected by MPE to reduce the impact of MPE on mobility and improve handover success rates.

[0170] Unrestricted signaling bearers refer to signaling bearers unaffected by MPE (Mean Differential Efforts), and can include SRB1, SRB2, and SRB3 in the signaling radio bearer (SRB). SRB1, SRB2, and SRB3 are mainly used to transmit control signaling, thereby reducing the impact of MPE on mobility. Restricted signaling bearers refer to signaling bearers affected by MPE, and can include SRB4 to SRB9. That is, signaling transmitted using SRB4 to SRB9 is affected by MPE, while signaling transmitted using SRB1, SRB2, and SRB3 is unaffected.

[0171] An unrestricted purpose refers to the transmission of uplink data without being affected by MPE (Mean While Employment). The unrestricted channel corresponding to an unrestricted purpose can include PRACH used for random access during handover. It is understood that the signaling transmitted via PRACH used for random access during handover is related to the handover procedure. Pre-setting the unrestricted channel corresponding to this purpose to be unaffected by MPE can reduce the impact of MPE on mobility and improve the handover success rate. Furthermore, it avoids unrestricting the signaling of all unrestricted channels, thus reducing radiation exposure to humans. The signaling transmitted via PRACH used for system information (SI) is independent of the handover procedure and can be affected by MPE, further reducing radiation exposure to humans.

[0172] Signalling transmitted on the PUCCH, such as channel quality information (CQI) reports, acknowledgment (ACK) messages, scheduling requests (SRs), and channel state information (CSI) reports, can be subject to MPE restrictions based on the purpose of the transmitted signaling. It can be understood that if the purpose of transmitting signaling via the PUCCH channel is related to the mobility of the terminal device, then that purpose can be determined as unrestricted.

[0173] Unrestricted scenarios refer to scenarios unaffected by MPE (Mobility Performance Issues), including handover scenarios, RRC (Real-Time Control) establishment scenarios, and RRC re-establishment scenarios. These scenarios are all related to the mobility of the terminal device. Presetting these scenarios to be unaffected by MPE can reduce the impact of MPE on mobility and improve the success rate of handover.

[0174] This application does not limit the method for identifying unrestricted scenarios. It can identify a terminal device as being in a handover scenario after the source base station sends a handover request to the terminal device. Alternatively, it can identify a terminal device as being in a handover scenario when the terminal device receives an RRC reconfiguration message (the second RRC reconfiguration message) that triggers handover. Or, it can identify a terminal device as being in an RRC re-establishment scenario when the terminal device enters an unrestricted active state from an idle state and sends an RRC establishment request message to the serving cell to establish a control signaling transmission channel.

[0175] This application does not limit the unlimited time period after the unlimited scene is identified, nor the unlimited process within the unlimited scene. The unlimited time period can be 1 minute, 30 seconds, etc., after the unlimited scene is identified. The unlimited process can be related to data configuration processes, etc.

[0176] In one possible example, before step S601, the method further includes: the source base station identifying that the terminal device is in an unrestricted scenario. That is, after the source base station identifies that the terminal device is in an unrestricted scenario, it sends indication information to the terminal device, thereby improving the effectiveness of the indication.

[0177] For example, when the source base station sends a handover request to the terminal device, if the source base station identifies that the subsequent process is a handover scenario, it sends an indication message to the terminal device to indicate that the terminal device is not affected by the MPE when it identifies an unrestricted scenario, or that the terminal device is not affected by the MPE during the unrestricted period after identifying an unrestricted scenario, or that the terminal device is not affected by the MPE when it identifies an unrestricted process in an unrestricted scenario.

[0178] It should be noted that after the terminal device recognizes that it is in an unrestricted scenario, it can decide on its own whether a certain period of time or certain processes will not be affected by MPE.

[0179] For example, when a terminal device receives an RRC reconfiguration message that triggers a handover, the terminal device recognizes this scenario as a handover scenario and can be exempt from MPE restrictions for 30 seconds after the handover scenario is recognized. The MPE restrictions are then reinstated when the handover scenario ends. Alternatively, the random access procedure within the handover scenario can be exempt from MPE restrictions, and the MPE restrictions are reinstated after the random access procedure ends or an RRC reconfiguration completion message is received.

[0180] S602. In response to the terminal device meeting the MPE constraint conditions, the terminal device processes the object to be restricted based on the instruction information.

On the other hand, when the terminal device meets the MPE restriction conditions, processing can be performed on the terminal device based on indication information of unrestricted objects and / or objects to be restricted in relation to MPE, which can also reduce the impact of MPE on mobility and improve the handover success rate.
