Description

Technical Field

[0002] In communication systems, when a terminal is in an idle or inactive state, it needs to continuously perform cell reselection to camp on a cell with higher priority or better signal quality. In existing technologies, terminal equipment typically determines whether to perform cell measurements based on frequency priority and measurement thresholds. However, this measurement mechanism not only incurs significant resource consumption for the terminal equipment but may also lead to inaccurate measurement results. Summary of the Invention

[0100] To better understand the cell reselection measurement method disclosed in this disclosure, the communication system to which this disclosure applies will be described first.

[0101] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure. The communication system may include, but is not limited to, a network device and a terminal device. Figure 1 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure. In actual applications, two or more network devices and two or more terminal devices may be included. Figure 1 The communication system shown is an example including a network device 11 and a terminal device 12.

[0102] It should be noted that the technical solutions of this disclosure can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, 5th Generation (5G) mobile communication systems, 5G New Radio (NR) systems, or other future new mobile communication systems.

[0103] The network device 11 in this disclosure is a network-side entity used for transmitting or receiving signals. For example, the network device 11 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This disclosure does not limit the specific technology or device form used in the network device. The network device provided in this disclosure can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure allows the protocol layer of a network device, such as a base station, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining part or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0104] The terminal device 12 in this disclosure is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of this disclosure do not limit the specific technology or device form used in the terminal device.

[0105] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0106] The method and apparatus for cell reselection measurement provided in this disclosure will be described in detail below with reference to the accompanying drawings.

[0107] Please see Figure 2 , Figure 2 This is a flowchart illustrating a cell reselection measurement method according to an embodiment of this disclosure, which is executed by a terminal device. Figure 2 As shown, the method may include, but is not limited to, the following steps:

[0108] Step 21: During the cell reselection process, determine whether to apply measurement restrictions to cells or frequencies not included in the reselection candidate list.

[0109] It should be noted that during cell reselection, the terminal device determines the target cell based on reselection conditions and criteria during communication. The terminal device then reads the system information of the target cell and determines whether the cell is a suitable cell based on the parameters in the system information. If it is, the terminal device reselects to that cell; otherwise, it determines whether to exclude the cell from the reselection candidate cells according to the protocol. For example, if the cell status indicates or is considered a barred cell due to the inability to obtain system information, that cell and / or other cells on the same frequency may be excluded from the reselection candidate cells for 300 seconds, etc.

[0110] If a cell or frequency is excluded from the reselection candidate cell list, meaning it is currently under reselection restriction and cannot be reselected as the target cell by the terminal device, then if the terminal device still measures cells or frequencies outside the reselection candidate list, it will not only cause power consumption but also occupy measurement opportunities for other reselection candidate frequencies or cells, leading to inaccurate measurement results for those other candidate frequencies or cells. Therefore, in this disclosure, during the terminal device's reselection process, it can determine whether to apply measurement restrictions to cells or frequencies outside the reselection candidate list as needed.

[0111] Optionally, the cell reselection process may include at least one of the following: intra-frequency cell reselection, inter-frequency cell reselection, and inter-system cell reselection.

[0112] Among them, intra-frequency cell reselection can be performed by the terminal device selecting a new serving cell from the list of reselection candidate cells with the same frequency point based on the frequency point of the currently serving cell.

[0113] Among them, inter-frequency cell reselection can be performed by the terminal device selecting a new serving cell from a list of reselection candidate cells with different frequency points based on the frequency point of the currently serving cell.

[0114] Inter-system cell reselection can involve the terminal device selecting a new serving cell from a list of reselection candidate cells within a different system, based on the system of its current serving cell. For example, if the terminal device's current serving cell is a 4G system, it can select a new serving cell from the reselection candidate cells included in a 5G system. This disclosure does not limit this to a specific method.

[0115] Optionally, measurement restrictions may include any of the following: not performing a measurement, performing measurement relaxation, or adding cells or frequencies not in the reselection candidate list to the reselection blacklist.

[0116] For example, if the measurement is restricted to not being performed, during the cell reselection process, if the terminal device detects a cell on a certain frequency point, but that cell is excluded from the reselection candidate list, the terminal device may not perform a measurement on that cell.

[0117] Alternatively, during cell reselection, if the terminal device determines that all cells on a certain frequency point have been excluded from the reselection candidate list, the terminal device may choose not to perform measurements on that frequency point. The frequency point for which measurements are not performed can be a high-priority frequency point, a frequency point of the same priority, or a low-priority frequency point. This disclosure does not limit this.

[0118] Alternatively, during the cell reselection process, if the terminal device determines that all co-frequency neighboring cells have been excluded from the reselection candidate list, the terminal device may not perform co-frequency cell measurement.

[0119] Optionally, the blacklist of cells to be reselected may include at least one of the following as indicated in the broadcast system message: Intra Freq Black Cell List, Intra Freq Black Cell List, and EUTRA-Freq Black Cell List.

[0120] Among them, broadcast system messages can be messages broadcast by the serving cell where the terminal device is currently located.

[0121] For example, during cell reselection, if a cell is excluded from the reselection candidate list, the terminal device will add that cell to the reselection blacklist. If measurement restrictions are determined to be enforced, the terminal device will not perform measurements on cells added to the reselection blacklist due to reselection restrictions when performing cell reselection measurements. Once the reselection restriction on a cell or frequency point is lifted, that cell or all cells under that frequency point can be removed from the reselection blacklist, and the reselection measurement evaluation can be re-executed.

[0122] By implementing the embodiments of this disclosure, the terminal device determines whether to apply measurement restrictions to cells or frequencies outside the reselection candidate list during the cell reselection process. Therefore, by restricting measurements to cells or frequencies outside the reselection candidate list, the terminal device avoids these cells or frequencies occupying measurement opportunities, ensuring the accuracy of the measurement results and reducing the power consumption of the terminal device.

[0123] Please see Figure 3 , Figure 3 This is a flowchart illustrating a cell reselection measurement method according to another embodiment of this disclosure, which is executed by a terminal device. Figure 3 As shown, the method may include, but is not limited to, the following steps:

[0124] Step 31: During the cell reselection process, determine whether to apply measurement restrictions to cells or frequencies not included in the reselection candidate list.

[0125] Optionally, the terminal device may determine whether to apply measurement restrictions to cells or frequencies outside the reselection candidate list based on the first indication information from the network device.

[0126] The first indication information is a message sent by the network device to the terminal device, which is used to instruct the terminal device whether to perform measurement restrictions on cells or frequencies outside the reselection candidate list.

[0127] Optionally, the terminal device may receive the first instruction information via a service cell broadcast system message.

[0128] Alternatively, the terminal device can also receive the first instruction information through proprietary signaling.

[0129] Optionally, the terminal device may also determine, according to the agreement, whether to impose measurement restrictions on cells or frequencies not included in the reselection candidate list.

[0130] Step 32: If it is determined that measurement restrictions are to be applied to cells or frequencies outside the reselection candidate list, determine the duration of the measurement restrictions.

[0131] Optionally, the terminal device can determine the duration of the measurement restriction based on the second indication information from the network device.

[0132] Alternatively, the terminal device can determine the duration of the measurement limit according to the agreement.

[0133] Optionally, the duration of the measurement constraint T1 and the duration of the reselection constraint T2 may be the same or different, and this disclosure does not limit this.

[0134] For example, if the duration of the measurement constraint T1 is the same as the duration of the reselection constraint T2, and the duration of the reselection constraint T2 is 300s, then the duration of the measurement constraint T1 is also 300s. Alternatively, the duration of the reselection constraint T2 can be at most 300s; for example, if T2 is 280s, then the duration of the measurement constraint T1 is also determined to be 280s. This disclosure does not impose any limitation on this.

[0135] When the duration of the measurement constraint T1 differs from the duration of the reselection constraint T2, and the duration of the reselection constraint T2 is 300s, then the duration of the measurement constraint T1 can be 200s, 250s, etc. Alternatively, the duration of the reselection constraint T2 can be at most 300s; for example, if T2 is 280s, then the duration of the measurement constraint T1 can be 200s, 260s, etc. This disclosure does not impose any limitations on this.

[0136] Optionally, the time at which the measurement restriction is lifted can be the same as or different from the time at which the reselection restriction is lifted; this disclosure does not impose any limitation on this.

[0137] Understandably, during cell reselection, if the duration of the measurement restriction is the same as the duration of the reselection restriction, then the measurement restriction will be lifted simultaneously when the cell or frequency reselection restriction is lifted. This avoids the situation where the terminal device continues to apply the measurement restriction to a cell or frequency whose reselection restriction has been lifted, even after the cell or frequency reselection restriction has been lifted, further ensuring the accuracy of the measurement results.

[0138] Correspondingly, during the cell reselection process, if the duration of the measurement restriction is unrelated to the duration of the reselection restriction, then within the determined duration of the measurement restriction, the measurement restriction is applied to cells or frequencies outside the reselection candidate list. After the measurement restriction is lifted, the measurement restriction is lifted to cells or frequencies outside the reselection candidate list. This reduces the power consumption of the terminal device within the duration of the measurement restriction and prevents cells or frequencies outside the reselection candidate list from occupying measurement opportunities.

[0139] By implementing the embodiments of this disclosure, during the cell reselection process, the terminal device determines the duration of the measurement restriction when it is determined that measurement restrictions will be applied to cells or frequencies outside the reselection candidate list. Thus, by applying measurement restrictions to cells or frequencies outside the reselection candidate list for the duration of the measurement restriction, and resuming normal measurement of the cells or frequencies after the measurement restriction is lifted, the terminal device avoids cells or frequencies outside the reselection candidate list occupying measurement opportunities. This not only ensures the accuracy of the measurement results but also reduces the power consumption of the terminal device.

[0140] Please see Figure 4 , Figure 4 This is a flowchart illustrating a cell reselection measurement method according to another embodiment of this disclosure, which is executed by a terminal device. Figure 4 As shown, the method may include, but is not limited to, the following steps:

[0141] Step 41: During the cell reselection process, determine whether to perform measurement relaxation on cells or frequencies not included in the reselection candidate list.

[0142] The implementation process of step 41 can be described in detail with reference to any embodiment of this disclosure, and will not be repeated here.

[0143] Step 42: Determine the measurement cycle during the measurement relaxation process.

[0144] Optionally, performing measurement relaxation may include determining at least one of the following measurement parameters: the number of measurements and the measurement cycle.

[0145] Optionally, the terminal device can determine the measurement parameters based on the third indication information from the network device.

[0146] Alternatively, the terminal device can determine the measurement parameters according to the agreement.

[0147] The number of measurements refers to the number of times the terminal device performs measurements on cells not included in the reselection candidate list.

[0148] It can be 1 time, 2 times, N times, etc., and this disclosure does not limit it.

[0149] Optionally, the measurement period can be the product of the terminal device's regular measurement period and a measurement relaxation factor. The measurement relaxation factor can be determined by third indication information from the network device, or it can be determined according to the protocol agreement; this disclosure does not limit this.

[0150] Alternatively, the measurement period can be determined based on the number of measurements. That is, the measurement period is the ratio of the duration of the measurement constraint to the number of measurements.

[0151] Alternatively, the measurement period can be a specific period configured for the network device or agreed upon by the protocol. For example, a measurement may be performed every 50 seconds, or every 100 seconds, etc. This disclosure does not limit this.

[0152] Optionally, the measurement parameters corresponding to different frequency points can be different or the same;

[0153] or,

[0154] The measurement parameters for different communities may be different or the same;

[0155] or,

[0156] The measurement parameters for terminal devices in different states may be different or the same;

[0157] or,

[0158] The measurement parameters for terminal devices in different services may be different or the same.

[0159] Step 43: In each measurement cycle, perform at least one measurement on cells or frequencies not included in the reselection candidate list.

[0160] Optionally, if any measurement period is aligned with a discontinuous reception (DRX) period, at least one measurement shall be performed on a cell or frequency not included in the reselection candidate list within any measurement period.

[0161] Alternatively, if any measurement period is not aligned with the DRX period, at least one measurement shall be performed on a cell or frequency not on the reselection candidate list within the DRX period following any measurement period.

[0162] Optionally, at least one measurement may be performed on cells or frequencies not included in the reselection candidate list within the first DRX cycle after any measurement cycle;

[0163] Alternatively, at least one measurement may be performed on a cell or frequency not on the reselection candidate list within the Xth DRX period following any measurement period, where X is a positive integer greater than 1.

[0164] By implementing the embodiments of this disclosure, when the terminal device determines to perform measurement relaxation on a cell or frequency point outside the reselection candidate list during the cell reselection process, it can first determine the measurement period, and then perform at least one measurement on the cell or frequency point outside the reselection candidate list in each measurement period. This avoids the cell or frequency point outside the reselection candidate list occupying too many measurement opportunities, which not only ensures the accuracy of the measurement results, but also reduces the power consumption of the terminal device.

[0165] Please see Figure 5, Figure 5 This is a flowchart illustrating a cell reselection measurement method according to another embodiment of this disclosure, which is executed by a terminal device. Figure 5 As shown, the method may include, but is not limited to, the following steps:

[0166] Step 51: During the cell reselection process, determine whether to perform measurement relaxation on cells or frequencies not included in the reselection candidate list.

[0167] The specific implementation of step 51 can be found in the detailed steps of other embodiments in this disclosure, and will not be described in detail here.

[0168] Step 52: Determine the number of measurements to be performed during the relaxation phase.

[0169] Optionally, the number of measurements may be indicated by the network device or determined according to the protocol; this disclosure does not limit this.

[0170] Step 53: Perform measurements on cells or frequencies not included in the reselection candidate list, based on the number of measurements performed.

[0171] It should be noted that after determining the number of measurements, when performing measurements on cells or frequencies outside the reselection candidate list, the terminal device must ensure that the measurement is performed within the DRX cycle.

[0172] Optionally, in response to the terminal device determining that the measurement time is not within a DRX cycle, it determines to perform a measurement on a cell or frequency point outside the reselection candidate list in the first DRX cycle or the Yth DRX cycle after the measurement time, where Y is a positive integer greater than 1.

[0173] Optionally, in response to the measurement time determined by the terminal device being within the DRX cycle, measurements are performed on cells or frequencies outside the reselection candidate list at the measurement time.

[0174] By implementing the embodiments of this disclosure, during the cell reselection process, the terminal device can determine the number of measurements to be performed on cells or frequencies outside the reselection candidate list. This allows the terminal device to first determine the number of measurements, and then perform measurements on cells or frequencies outside the reselection candidate list based on the number of measurements. This avoids cells or frequencies outside the reselection candidate list occupying too many measurement opportunities, which not only ensures the accuracy of the measurement results but also reduces the power consumption of the terminal device.

[0175] Please see Figure 6 , Figure 6 This is a flowchart illustrating a cell reselection measurement method according to another embodiment of this disclosure, which is executed by a terminal device. Figure 6 As shown, the method may include, but is not limited to, the following steps:

[0176] Step 61: During the cell reselection process, determine whether to perform measurement relaxation on cells or frequencies not included in the reselection candidate list.

[0177] Step 62: Perform measurements on cells or frequencies not included in the reselection candidate list based on the measurement parameters.

[0178] The specific implementation of steps 61 and 62 can be found in the detailed steps of other embodiments in this disclosure, and will not be described in detail here.

[0179] Step 63: After the measurement restrictions are lifted, the measurement result can be determined based on K measurement values, where K is a positive integer.

[0180] Optionally, the value of K can be set as needed, such as 2, 3, etc. The K measurement values ​​can be the latest measurement value obtained within the effective duration of the measurement limit, or the measurement values ​​corresponding to a specified number of measurements within the effective duration of the measurement limit, etc., and this disclosure does not limit them.

[0181] Optionally, after the measurement restrictions are lifted, the measurement results of a cell are determined based on the K measurement values ​​corresponding to cells outside the reselection candidate list.

[0182] Optionally, after the measurement restrictions are lifted, the measurement result of the frequency point is determined based on the K measurement values ​​corresponding to the frequency points outside the reselection candidate list.

[0183] Alternatively, if more accurate measurement results are required after the measurement restrictions are lifted, measurements can be performed on cells or frequencies not included in the reselection candidate list, and this disclosure does not limit this.

[0184] It should be noted that the terminal equipment needs to filter at least two measurements to determine the measurement result of the cell or frequency point, and the measurement time interval between the two measurements should not be less than half of the measurement period.

[0185] By implementing the embodiments of this disclosure, the terminal device can determine the measurement result based on K measurement values ​​after the measurement restriction is lifted. Therefore, when the terminal device performs measurement relaxation on cells or frequencies outside the reselection candidate list, it performs measurements on those cells or frequencies. Thus, after the reselection restriction is lifted, the terminal device can directly use the measurement values ​​from when the measurement relaxation was performed on cells or frequencies outside the reselection candidate list to determine the measurement result, reducing latency.

[0186] Please see Figure 7 , Figure 7 This is a flowchart illustrating a cell reselection measurement method according to another embodiment of this disclosure, which is executed by a terminal device. Figure 7As shown, the method may include, but is not limited to, the following steps:

[0187] Step 71: If it is determined that a measurement restriction is applied to a cell or frequency outside the reselection candidate list, in response to determining that a paging time window (PTW) exists within the duration of the measurement restriction, at least one measurement is performed on the cell or frequency outside the reselection candidate list within the DRX period of the PTW.

[0188] Understandably, when the terminal device is configured with extended DRX, if a paging window exists within the duration of the measurement limit, at least one measurement can be performed on cells or frequencies outside the reselection candidate list within the PTW's DRX cycle, further reducing the power consumption of the terminal device.

[0189] Optionally, if it is determined that there is a PTW within the duration of the measurement limit, at least one measurement shall be performed on a cell or frequency not in the reselection candidate list within the DRX cycle of a PTW.

[0190] Alternatively, if it is determined that at least two PTWs exist within the duration of the measurement limitation, at least one measurement is performed on a cell or frequency outside the reselection candidate list within the DRX cycle of at least one of the at least two PTWs.

[0191] For example, the terminal device can perform at least one measurement on a cell or frequency not on the reselection candidate list within each of the two PTW DRX cycles. Alternatively, the terminal device can, according to regulations, determine to perform at least one measurement on a cell or frequency not on the reselection candidate list within each of the first two PTW DRX cycles. Or, the terminal device can, according to regulations, determine to perform at least one measurement on a cell or frequency not on the reselection candidate list within each of the Nth and N+Mth PTW DRX cycles.

[0192] The terminal device may also perform at least one measurement for cells or frequencies not included in the reselection candidate list within at least two PTW DRX cycles. For example, the terminal device may perform at least one measurement within each PTW DRX cycle. Alternatively, the terminal device may, according to regulations, perform at least one measurement within each P PTM DRX cycle.

[0193] Optionally, the terminal device is configured with an extended DRX, which, in response to determining that no paging time window (PTW) exists during the duration of the measurement restriction, does not perform measurements on cells or frequencies outside the reselection candidate list if it is determined that measurement restrictions are applied to cells or frequencies outside the reselection candidate list.

[0194] By implementing embodiments of this disclosure, when a terminal device determines that a measurement restriction is to be applied to a cell or frequency point outside the reselection candidate list, in response to determining that a paging time window (PTW) exists within the duration of the measurement restriction, the terminal device performs at least one measurement on the cell or frequency point outside the reselection candidate list within the DRX cycle of the PTW. Therefore, by performing at least one measurement on the cell or frequency point outside the reselection candidate list within the DRX cycle of the PTW, the terminal device not only further reduces power consumption but also ensures the accuracy of the measurement results.

[0195] Please see Figure 8 , Figure 8 This is a flowchart illustrating a cell reselection measurement method according to another embodiment of this disclosure, which is executed by a network device. Figure 8 As shown, the method may include, but is not limited to, the following steps:

[0196] Step 81: Send a first indication message to the terminal device, wherein the first indication message is used to indicate whether to perform measurement restrictions on cells or frequencies outside the reselection candidate list during the cell reselection process.

[0197] Optionally, the network device may send the first instruction information to the terminal device via a serving cell broadcast system message.

[0198] Alternatively, network devices can send the first instruction information to the terminal device via proprietary signaling.

[0199] Optionally, the cell reselection process may include at least one of the following: intra-frequency cell reselection, inter-frequency cell reselection, and inter-system cell reselection.

[0200] Among them, intra-frequency cell reselection can be performed by the terminal device selecting a new serving cell from the list of reselection candidate cells with the same frequency point based on the frequency point of the currently serving cell.

[0201] Among them, inter-frequency cell reselection can be performed by the terminal device selecting a new serving cell from a list of reselection candidate cells with different frequency points based on the frequency point of the currently serving cell.

[0202] Inter-system cell reselection can involve the terminal device selecting a new serving cell from a list of reselection candidate cells within a different system, based on the system of its current serving cell. For example, if the terminal device's current serving cell is a 4G system, it can select a new serving cell from the reselection candidate cells included in a 5G system. This disclosure does not limit this to a specific method.

[0203] Optionally, the blacklist of cells to be reselected may include at least one of the following as indicated in the broadcast system message: a blacklist of cells on the same frequency, a blacklist of cells on different frequencies, and a blacklist of cells on different systems.

[0204] Among them, broadcast system messages can be messages broadcast by the serving cell where the terminal device is currently located.

[0205] For example, during cell reselection, if a cell is excluded from the reselection candidate list, the terminal device will add that cell to the reselection blacklist. If measurement restrictions are determined to be enforced, the terminal device will not perform measurements on cells added to the reselection blacklist due to reselection restrictions when performing cell reselection measurements. Once the reselection restriction on a cell or frequency point is lifted, that cell or all cells under that frequency point can be removed from the reselection blacklist, and the reselection measurement evaluation can be re-executed.

[0206] Optionally, measurement restrictions may include any of the following: not performing a measurement, performing measurement relaxation, or adding cells or frequencies not in the reselection candidate list to the reselection blacklist.

[0207] For example, if the measurement is restricted to not being performed, during the cell reselection process, if the terminal device detects a cell on a certain frequency point, but that cell is excluded from the reselection candidate list, the terminal device may not perform a measurement on that cell.

[0208] Alternatively, during cell reselection, if the terminal device determines that all cells on a certain frequency point have been excluded from the reselection candidate list, the terminal device may choose not to perform measurements on that frequency point. The frequency point for which measurements are not performed can be a high-priority frequency point, a frequency point of the same priority, or a low-priority frequency point. This disclosure does not limit this.

[0209] Alternatively, during the cell reselection process, if the terminal device determines that all co-frequency neighboring cells have been excluded from the reselection candidate list, the terminal device may not perform co-frequency cell measurement.

[0210] By implementing the embodiments of this disclosure, the network device sends a first indication message to the terminal device, wherein the first indication message is used to indicate whether to perform measurement restrictions on cells or frequencies outside the reselection candidate list during the cell reselection process. Thus, by instructing the terminal device to restrict measurements on cells or frequencies outside the reselection candidate list, the network device avoids these cells or frequencies occupying measurement opportunities, ensuring the accuracy of the measurement results and reducing the power consumption of the terminal device.

[0211] Please see Figure 9 , Figure 9This is a flowchart illustrating a cell reselection measurement method according to another embodiment of this disclosure, which is executed by a network device. Figure 9 As shown, the method may include, but is not limited to, the following steps:

[0212] Step 91: Send a second indication message to the terminal device, wherein the second indication message is used to indicate the duration of the measurement limit.

[0213] Optionally, the duration of the measurement constraint T1 and the duration of the reselection constraint T2 may be the same or different, and this disclosure does not limit this.

[0214] For example, if the duration of the measurement constraint T1 is the same as the duration of the reselection constraint T2, and the duration of the reselection constraint T2 is 300s, then the duration of the measurement constraint T1 is also 300s. Alternatively, the duration of the reselection constraint T2 can be at most 300s; for example, if T2 is 280s, then the duration of the measurement constraint T1 is also determined to be 280s. This disclosure does not impose any limitation on this.

[0215] When the duration of the measurement constraint T1 differs from the duration of the reselection constraint T2, and the duration of the reselection constraint T2 is 300s, then the duration of the measurement constraint T1 can be 200s, 250s, etc. Alternatively, the duration of the reselection constraint T2 can be at most 300s; for example, if T2 is 280s, then the duration of the measurement constraint T1 can be 200s, 260s, etc. This disclosure does not impose any limitations on this.

[0216] Optionally, the time at which the measurement restriction is lifted can be the same as or different from the time at which the reselection restriction is lifted; this disclosure does not impose any limitation on this.

[0217] By implementing the embodiments of this disclosure, the network device sends second indication information to the terminal device to indicate the duration of the measurement restriction. This enables the terminal device to apply the measurement restriction to cells or frequencies outside the reselection candidate list if it determines that a measurement restriction should be applied. Within the duration of the measurement restriction, the terminal device applies the measurement restriction to those cells or frequencies outside the reselection candidate list. This avoids cells or frequencies outside the reselection candidate list occupying measurement opportunities, ensuring the accuracy of the measurement results and reducing the power consumption of the terminal device.

[0218] Please see Figure 10 , Figure 10 This is a flowchart illustrating a cell reselection measurement method according to another embodiment of this disclosure, which is executed by a network device. Figure 10 As shown, the method may include, but is not limited to, the following steps:

[0219] Step 101: Send third indication information to the terminal device, wherein the third indication information is used to indicate the measurement parameters.

[0220] The measurement parameters include at least one of the following: the number of measurements and the measurement cycle.

[0221] The number of measurements can be the number of times the terminal device, as instructed by the network device, performs measurements on cells outside the reselection candidate list. It can be 1 time, 2 times, N times, etc., and this disclosure does not limit this.

[0222] Optionally, the measurement period can also be determined based on the number of measurements. That is, the measurement period is the ratio of the duration of the measurement constraint to the number of measurements.

[0223] Alternatively, the measurement period can be a specific period agreed upon by the network device according to the protocol. For example, a measurement may be performed every 50 seconds, or every 100 seconds, etc. This disclosure does not limit this.

[0224] Alternatively, the third indication information sent by the network device can indicate a measurement relaxation factor. The terminal device can then determine the measurement period based on the product of the measurement relaxation factor indicated by the network device and the regular measurement period.

[0225] Optionally, the measurement parameters may be different or the same for different frequency points;

[0226] or,

[0227] The measurement parameters may be different or the same for different communities;

[0228] or,

[0229] The measurement parameters for terminal devices in different states may be different or the same.

[0230] or,

[0231] The measurement parameters for terminal devices in different services may be different or the same.

[0232] By implementing the embodiments of this disclosure, the network device sends third indication information to the terminal device, wherein the third indication information is used to indicate measurement parameters, so that the terminal device, upon determining that measurement relaxation should be performed on cells or frequencies outside the reselection candidate list, performs measurements on cells or frequencies outside the reselection candidate list according to the measurement parameters. This avoids cells or frequencies outside the reselection candidate list occupying too many measurement opportunities, ensuring not only the accuracy of the measurement results but also reducing the power consumption of the terminal device.
