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

[0030] The cell activation method, device, electronic device, and medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0031] The cell activation method, apparatus, electronic device, and medium provided in the embodiments of the present application can be applied to a scenario in which an electronic device adds / activates a secondary cell to implement cell aggregation.

[0032] In related art, when an electronic device implements CA by activating a secondary cell, it may activate an Scell ​​that meets a corresponding signal quality threshold, such as activating the Scell ​​with the best signal quality, to implement CA. In this way, because Scell ​​activation is performed based on the signal quality of Scell ​​1, the network resources of the secondary cell activated by the electronic device may be far greater than the network resources actually required by the electronic device, resulting in a waste of network resources.

[0033] Furthermore, the Scell ​​with the best signal quality does not necessarily have the best transmission performance. In a real network environment, a good signal may be accompanied by a data interruption (i.e., internet access failure). Furthermore, if every electronic device selects the secondary cell with the best signal quality for activation, the signal quality and transmission performance of this secondary cell may deteriorate, resulting in poor CA effectiveness across the entire network.

[0034] In the cell activation method provided in an embodiment of the present application, an electronic device may send a first message to a network device, the first message being used to request a secondary cell for performing a communication service. The first message includes first CA parameters required by the electronic device, which include network resource parameters required by the electronic device and CA capability parameters of the electronic device. The network device may then receive the first message, determine a first secondary cell based on the first message, and send a secondary cell list to the electronic device, the secondary cell list including information about the first secondary cell. Upon receiving the secondary cell list, the electronic device may implement CA by activating at least one of the first secondary cells. In this manner, because the electronic device may carry the network resource parameters required by the electronic device and the capability information of the electronic device in the first message requesting the secondary cell for the communication service from the network device, the network device may configure a secondary cell suitable for the electronic device based on the network resource parameters required by the electronic device and the capability information of the electronic device, thereby ensuring good CA performance for the electronic device while avoiding waste of network resources.

[0035] Furthermore, since the network device can configure a secondary cell for the electronic device based on the first CA parameter reported by the electronic device, different secondary cells can be configured for electronic devices that report different CA parameters, thereby avoiding the probability of electronic devices with different CA requirements activating the same secondary cell, thereby improving the network resource scheduling level and CA performance of the entire network.

[0036] An embodiment of the present application provides a cell activation method. FIG2 shows a flow chart of the cell activation method provided by the embodiment of the present application. As shown in FIG2 , the cell activation method provided by the embodiment of the present application may include steps 201 to 206.

[0037] Step 201: An electronic device sends a first message to a network device.

[0038] Step 202: The network device receives a first message.

[0039] The first message may be used to request a secondary cell to perform a communication service. The first message may include a first CA parameter. The first CA parameter includes network resource parameters required by the electronic device and capability information of the electronic device.

[0040] Optionally, the first message may be an A4 measurement report.

[0041] It should be noted that the electronic device in the embodiment of the present application refers to an electronic device with CA terminal capability or supporting CA.

[0042] Optionally, the network resource parameters required by the electronic device may include at least one of the following: the number of data packets currently to be sent by the electronic device, the network speed required by the electronic device, the throughput required by the electronic device, the bandwidth required by the electronic device, etc.

[0043] Optionally, the capability information of the electronic device may indicate at least one of the following: the number of secondary cells supported by the electronic device, the frequency domain supported by the electronic device, the bandwidth supported by the electronic device, the network type supported by the electronic device, etc.

[0044] The number of secondary cells supported by the electronic device may be: the number of secondary cells that can be activated by the electronic device and used for CA.

[0045] The network types supported by the electronic device may include: LTE, 5G or 6G, etc.

[0046] Optionally, the first CA parameter may further include: a signal state parameter of a primary cell of the electronic device, where the signal state parameter is used to determine whether the electronic device needs to add a secondary cell to assist in communication services.

[0047] For example, if the signal state parameter of the primary cell of the electronic device is less than or equal to the signal state parameter threshold, it means that the electronic device needs to add a secondary cell to assist in communication services.

[0048] Optionally, the signal status parameter may include at least one of the following: required signal status, signal-to-noise ratio of the primary cell, signal value of the primary cell, signal measurement strength of the primary cell, network speed of the primary cell, etc.

[0049] Optionally, the electronic device requests a secondary cell with CA capability. The purpose of the electronic device requesting the secondary cell is to realize carrier aggregation by activating the secondary cell requested by the electronic device, so as to perform communication services through the aggregated carrier.

[0050] Step 203: The network device determines a first secondary cell according to the first CA parameter.

[0051] In the embodiment of the present application, the first secondary cell is determined based on the first CA parameter. Since the first secondary cell is determined by the network device based on the first CA parameter reported by the electronic device, and the first CA parameter can represent the CA requirement of the electronic device, it can be ensured that the first secondary cell meets the CA requirement of the electronic device.

[0052] Optionally, after receiving the first message, the network device may parse the first message to obtain and save the first CA parameter; and then the electronic device may determine the first secondary cell according to the first CA parameter.

[0053] Optionally, the first secondary cell may be a CA cell set, wherein a CA cell set refers to a network device configuring several cells into a logical set, where only cells in the set are allowed to perform carrier aggregation, and the network device may configure relevant parameters of the CA cell set.

[0054] Step 204: The network device sends the secondary cell list to the electronic device.

[0055] Step 205: The electronic device receives a secondary cell list.

[0056] The secondary cell list includes information of the first secondary cell.

[0057] Optionally, after determining the first secondary cell, the network device may send the secondary cell list to the electronic device through any possible message.

[0058] Optionally, the network device sending the secondary cell list to the electronic device may include: the network device sending the secondary cell list to the electronic device through a radio resource control (RRC) reconfiguration message.

[0059] Optionally, the above-mentioned RRC reconfiguration message may be RRC reconfiguration signaling.

[0060] Optionally, the information of the first secondary cell may include a cell identifier or a cell number of the first secondary cell.

[0061] Step 206: The electronic device activates at least one secondary cell in the first secondary cell.

[0062] Optionally, the electronic device may activate all or part of the secondary cells in the first secondary cell, which may be specifically determined according to the number of secondary cells supported by the electronic device and the secondary cells in the first secondary cell, and is not limited in the embodiment of the present application.

[0063] Optionally, the electronic device activating the at least one secondary cell means that the electronic device adds the at least one secondary cell to the wireless network by configuring parameters, so that the at least one secondary cell can provide wireless signal coverage and communication services for the electronic device.

[0064] In the cell activation method provided in the embodiment of the present application, since the electronic device can carry the network resource parameters required by the electronic device and the capability information of the electronic device in the first message requesting the network device for the secondary cell for communication services, the network device can comprehensively configure the secondary cell suitable for the electronic device according to the network resource parameters required by the electronic device and the capability information of the electronic device, thereby avoiding waste of network resources on the basis of ensuring that the electronic device has good CA performance.

[0065] Optionally, the above step 201 may include the following step 201a.

[0066] Step 201a: When an abnormality occurs in the communication service of the electronic device, the electronic device sends a first message to the network device.

[0067] It can be understood that when an abnormality occurs in the communication service, such as when the current network resources of the electronic device are insufficient, the electronic device can request a secondary cell for the communication service from the network device, thereby continuing the communication service of the electronic device by CA the network resources of the requested secondary cell and the cell to which the electronic device is currently connected.

[0068] Optionally, the abnormality in the communication service of the electronic device may include at least one of the following:

[0069] The data packets to be transmitted are blocked;

[0070] The packet loss rate of the data packet is greater than or equal to the packet loss rate threshold;

[0071] The number of data packets to be transmitted is greater than or equal to the maximum transmission number of the cell to which the electronic device is currently connected.

[0072] It should be noted that, in actual implementation, abnormalities in the communication services of electronic devices may also include any other possible situations, such as the electronic device detecting that the network quality is less than or equal to the network quality threshold, the electronic device detecting that the transmission rate of the electronic device is less than or equal to the rate threshold, etc.

[0073] Optionally, when an electronic device is interacting with a network device, if a data packet to be transmitted or received by the electronic device is blocked, the data packet sent or received by the electronic device is incomplete (that is, the packet loss rate of the data packet of the electronic device is greater than or equal to the packet loss rate threshold), and the amount of data packets transmitted or received by the electronic device is greater than or equal to the maximum transmission number of the cell to which the electronic device is currently connected, the electronic device can send the network resource parameters currently required by the electronic device, the capability information of the electronic device, and the signal state parameters currently required by the electronic device to the network device, in the hope that the network device will allocate an Scell ​​to the electronic device for communication services.

[0074] In this way, since the electronic device sends the first message to the network device when an abnormality occurs in the communication service of the electronic device, waste of network resources can be avoided and signaling overhead of the electronic device can be saved.

[0075] Optionally, the above step 203 may include the following steps A and B.

[0076] Step A: The network device performs cell measurement on K sixth secondary cells to obtain K CA parameters.

[0077] The K sixth secondary cells may be all secondary cells within the current coverage of the network device, and K is an integer greater than 1.

[0078] Optionally, the K CA parameters correspond one-to-one to the K secondary cells.

[0079] Optionally, the CA parameter of the secondary cell may represent the CA capability of the secondary cell.

[0080] Optionally, the CA parameters of the secondary cell may include: network resource parameters of the secondary cell, capability information of the secondary cell, signal state parameters of the secondary cell, etc.

[0081] For other descriptions of the CA parameters of the secondary cell, refer to the above description of the first CA parameters.

[0082] Step B: The network device determines a first secondary cell according to the K CA parameters and the first CA parameter.

[0083] Optionally, the network device may determine the first secondary cell according to the matching degree between the K CA parameters and the first CA parameter, so as to ensure that the CA capability of the first secondary cell is adapted to the CA requirement of the electronic device.

[0084] In this way, after receiving the first information sent by the electronic device, the network device can perform cell measurement on the secondary cell within the current coverage area and determine the first secondary cell allocated to the electronic device based on the K CA parameters and the first CA parameter obtained by the measurement. Therefore, the electronic device can avoid measuring the secondary cell, thereby reducing the calculation amount and power consumption of the electronic device and improving the response speed of the electronic device.

[0085] It should be noted that the capability information of the electronic device may indicate the number of secondary cells supported by the electronic device. The network device may determine the first secondary cell in different ways depending on the number of secondary cells supported by the electronic device.

[0086] The following describes a manner in which the network device determines the first secondary cell according to the K CA parameters and the first CA parameter.

[0087] The first method: the above step B may include the following step B1.

[0088] Step B1: When the capability information of the electronic device indicates that the electronic device supports one secondary cell, the network device may determine a secondary cell among the K sixth secondary cells whose CA parameters meet the first CA parameters as the first secondary cell.

[0089] It can be understood that the CA parameters of each secondary cell in the first secondary cell meet the first CA parameters. In other words, the electronic device can improve the transmission performance of the electronic device by randomly activating any secondary cell in the first secondary cell.

[0090] Optionally, the electronic device may activate a secondary cell in the first cell to aggregate a carrier of the secondary cell with a carrier of a primary cell of the electronic device, so as to collaboratively perform communication services through the aggregated carriers.

[0091] In the embodiment of the present application, the primary cell of the electronic device is a cell with CA capability.

[0092] It should be noted that the CA parameters of the secondary cell satisfying the first CA parameters can be understood as: the network resource parameters of the secondary cell match the network resource parameters required by the electronic device, and the capability information of the secondary cell matches the capability information of the electronic device.

[0093] For example, if the electronic device supports the LTE network and the secondary cell also supports the LTE network, it is determined that the capability information of the secondary cell matches the capability information of the electronic device.

[0094] For example, the network resource parameters required by the electronic device include network speed. If the network speed supported by the bandwidth of a secondary cell is greater than or equal to the network speed required by the electronic device, it is determined that the network resource parameters of the secondary cell match the network resource parameters required by the electronic device.

[0095] In this way, since the network device can determine all secondary cells whose CA parameters meet the first CA parameters as first secondary cells, the electronic device can activate any secondary cell in the first secondary cells according to its usage needs to achieve CA. This can improve the flexibility of the electronic device in activating secondary cells.

[0096] The second method: the above step B can be implemented through the following step B1.

[0097] Step B1: When the capability information of the electronic device indicates that the electronic device supports L secondary cells, the network device may determine a secondary cell in at least one group of secondary cells as a first secondary cell.

[0098] Each group of secondary cells may include L fourth secondary cells whose sum of CA parameters in the K sixth secondary cells meets the first CA parameter, where L is an integer greater than 1.

[0099] In the embodiment of the present application, at least one secondary cell in different groups of secondary cells is different. For example, the first group of secondary cells includes secondary cell 1 and secondary cell 2, and the second group of secondary cells includes secondary cell 2 and secondary cell 3.

[0100] It can be understood that the network device may first sum the CA parameters of the L fourth secondary cells in each group of secondary cells to obtain a total CA parameter; and then determine whether the total CA parameter is the first CA parameter.

[0101] For other descriptions on the sum of the CA parameters of the secondary cell satisfying the first parameter, refer to the related description on the CA parameters of the secondary cell satisfying the first CA parameter in the above first manner.

[0102] It can be understood that any group of secondary cells in the at least one group of secondary cells can improve the transmission performance of the electronic device.

[0103] In this way, when the capability information of the electronic device represents or indicates that the electronic device supports L secondary cells, because the network device can determine the secondary cells in all secondary cell groups whose sum of CA parameters satisfies the first CA parameter as the first secondary cell, the electronic device can activate any one group of secondary cells in the first secondary cell group according to its usage requirements to implement CA. This can improve the flexibility of the electronic device in activating secondary cells.

[0104] Optionally, after the above steps B1 and B2, the cell activation method provided in the embodiment of the present application may further include the following step 207.

[0105] Step 207: The network device adds the cell mark information to the secondary cell list.

[0106] The cell mark information may be used to indicate that the CA parameter of the second secondary cell in the first secondary cell satisfies the first condition.

[0107] It can be understood that the cell mark information is used to mark the second secondary cell in the first secondary cell.

[0108] It should be noted that the CA parameters of the second secondary cell meeting the first condition can be understood as: the CA parameters of the second secondary cell are highly compatible with the CA requirements of the electronic device. In other words, the second secondary cell is the secondary cell that is most compatible with the communication service of the electronic device.

[0109] For example, an electronic device requires a network resource of 5 packets / second, and the network speeds of the secondary cells within the coverage area of ​​the network device are 4 packets / second, 3 packets / second, 6 packets / second, and 8 packets / second, respectively. The network device can determine that the secondary cells that meet the network resource parameters required by the electronic device (i.e., meet the first CA parameters) include: secondary cells with network speeds of 6 packets / second and 8 packets / second, and determine that the CA parameters that meet the first condition are: secondary cells with a network speed of 6 packets / second.

[0110] Optionally, in the first manner, the second secondary cell is a secondary cell whose CA parameters meet the first condition.

[0111] Optionally, in the second manner, the second secondary cell is a group of secondary cells whose sum of CA parameters satisfies the first condition. The cell marker information is specifically used to mark each secondary cell in the group of secondary cells. For example, assuming that secondary cell 1, secondary cell 2, and secondary cell 3 in the first secondary cell form a group of secondary cells, the secondary cell list includes three pieces of cell marker information, corresponding to the cell identifiers of secondary cell 1, secondary cell 2, and secondary cell 3, respectively.

[0112] In this way, since the network device can instruct the electronic device to activate a specific secondary cell in the first secondary cell by adding cell mark information to the secondary cell list, the electronic device does not need to measure and screen the secondary cells again, thereby saving power consumption of the electronic device and improving the response speed of the electronic device.

[0113] Optionally, the first condition may include any of the following:

[0114] The matching degree between the CA parameter and the first CA parameter is greater than or equal to a first threshold;

[0115] The matching degree between the CA parameter and the first CA parameter is the maximum matching degree in the target matching degree set, and the target matching degree set may include any one of the first matching degree set and the second matching degree set.

[0116] The first matching degree set may include: a matching degree between at least one second CA parameter and a first CA parameter, where the second CA parameter is the sum of CA parameters of a group of secondary cells in at least one group of secondary cells, or each second CA parameter is the sum of CA parameters of L third secondary cells in the first secondary cell.

[0117] The second matching degree set may include matching degrees between each CA parameter in the first secondary cell and the first CA parameter.

[0118] The different second CA parameters may be the sum of CA parameters of L different fourth secondary cells.

[0119] Optionally, the CA parameters of the second secondary cell satisfying the first condition may include:

[0120] In a case where the second secondary cell includes L secondary cells, a sum of CA parameters of the L secondary cells satisfies the first condition;

[0121] In the case that the second secondary cell includes one secondary cell, the CA parameter of the one secondary cell satisfies the first condition.

[0122] Optionally, the sum of the CA parameters of the L secondary cells satisfies the first condition, which may include any one of the following:

[0123] A matching degree between the sum of the CA parameters of the L secondary cells and the first CA parameter is greater than or equal to a first threshold;

[0124] The matching degree between the sum of the CA parameters of the L secondary cells and the first CA parameter is the maximum matching degree in the first matching degree set.

[0125] The first matching degree set includes a matching degree between at least one second CA parameter and the first CA parameter, where each second CA parameter is the sum of the CA parameters of L third secondary cells in the first secondary cell. It will be appreciated that the L secondary cells in each group of the at least one group of secondary cells are referred to as L fourth secondary cells. In other words, the at least one second CA parameter is the sum of the CA parameters of L specific secondary cells among the K sixth secondary cells.

[0126] In this way, since L secondary cells whose matching degree between the sum of the first secondary cell CA parameters and the first CA parameters is greater than or equal to the first threshold can be marked, or L secondary cells whose matching degree between the sum of the CA parameters in the first secondary cell and the first CA parameters is the greatest can be marked, the flexibility of configuring the most suitable secondary cell for an electronic device supporting L secondary cells can be improved.

[0127] Optionally, the CA parameters of the secondary cell satisfying the first condition may include any one of the following:

[0128] A matching degree between the CA parameter of the secondary cell and the first CA parameter is greater than or equal to a first threshold;

[0129] The matching degree between the CA parameters of the one secondary cell and the first CA parameters is the maximum matching degree in the second matching degree set, and the second matching degree set includes the matching degrees between each secondary cell in the first secondary cell and the first CA parameters.

[0130] In this way, since one secondary cell in which the degree of match between the sum of the first secondary cell CA parameters and the first CA parameters is greater than or equal to the first threshold can be marked, or one secondary cell in the first secondary cell in which the degree of match between the sum of the CA parameters and the first CA parameters is the greatest can be marked, the flexibility of configuring the most suitable secondary cell for an electronic device supporting one secondary cell can be improved.

[0131] In a third embodiment, the above step B may include the following step B3.

[0132] Step B3: When the capability information of the electronic device indicates that the electronic device supports one secondary cell, the network device determines a secondary cell among the K sixth secondary cells whose CA parameters meet the first CA parameters and the first condition as the first secondary cell.

[0133] For the description of the first condition, refer to the relevant description of the first condition in the above second method.

[0134] In this way, when the capability information of the electronic device indicates that the electronic device supports one secondary cell, since the network device determines the secondary cell whose CA parameter satisfies the first CA parameter and the first condition among the K sixth secondary cells as the first secondary cell, and the first condition can indicate the secondary cell with the best adaptability between the first secondary cell and the first CA parameter, that is, the network device allocates the first secondary cell that best meets the CA requirements of the electronic device to the electronic device, so that the electronic device can directly implement CA by activating the first secondary cell.

[0135] In a fourth embodiment, the above step B may include the following step B4.

[0136] Step B4: When the capability information of the electronic device indicates that the electronic device supports L secondary cells, the network device determines a secondary cell in the first group of secondary cells as a first secondary cell, where L is an integer greater than 1.

[0137] The first group of secondary cells includes L secondary cells whose sum of CA parameters in the K sixth secondary cells meets the first CA parameter and the first condition.

[0138] In this way, when the capability information of the electronic device indicates that the electronic device supports L secondary cells, since the network device determines the first group of secondary cells in which the sum of the CA parameters of the K sixth secondary cells satisfies the first CA parameter and the first condition as the first secondary cell, and the first condition can indicate the secondary cell with the best adaptability between the first secondary cell and the first CA parameter, that is, the network device allocates the first secondary cell that best meets the CA requirements of the electronic device to the electronic device, so that the electronic device can directly implement CA by activating the first secondary cell.

[0139] Optionally, the above step 206 may include the following step 206a or step 206b: In the above third and fourth manners, the electronic device performs step 206a, and in the above first and second manners, the electronic device performs step 206b.

[0140] Step 206a: When the secondary cell list does not include cell mark information, the electronic device activates all secondary cells in the first secondary cell.

[0141] Optionally, in the third and fourth methods above, the electronic device executes step 206a.

[0142] Optionally, after step 206a, if the communication service of the electronic device is abnormal, the electronic device may request the network device again for a secondary cell for communication service, such as repeating steps 201 to 205.

[0143] Step 206a: When the secondary cell list includes the cell mark information, the electronic device activates the second secondary cell corresponding to the cell mark information in the first secondary cell.

[0144] The second secondary cell may be part of the first secondary cell. The cell identification information may be used to indicate that the CA parameters of the second secondary cell meet the first condition.

[0145] In this way, since the electronic device can adaptively activate all or part of the first secondary cell indicated in the secondary cell list according to whether the cell mark information is included in the secondary cell list, without the need to perform cell measurement on the first secondary cell, the calculation amount of the electronic device can be saved and the efficiency of the electronic device in activating the cell can be improved.

[0146] Optionally, after the above step 206b, the cell activation method provided in the embodiment of the present application may further include the following steps 208 and 209.

[0147] Step 208: When an abnormality occurs in the communication service of the electronic device, the electronic device performs cell measurement on the first secondary cell to obtain CA parameters of the first secondary cell.

[0148] It can be understood that the electronic device obtains the CA parameters of the first secondary cell, which means that the electronic device performs cell measurement on all the secondary cells in the first secondary cell to obtain the CA parameters of all the secondary cells in the first secondary cell.

[0149] Step 209: The electronic device deactivates the fourth secondary cell and activates the fifth secondary cell according to the CA parameters of the first secondary cell.

[0150] The fourth secondary cell is a secondary cell of the second secondary cell whose CA parameter is less than or equal to the second threshold;

[0151] The fifth secondary cell is a secondary cell among the first secondary cells except the second secondary cell and whose CA parameter is greater than the second threshold.

[0152] It is understood that deactivating the fourth secondary cell may include terminating activation or canceling activation of the fourth secondary cell. Deactivation is the reverse operation of activation. After the electronic device deactivates the fourth secondary cell, the fourth secondary cell no longer provides wireless signal coverage and communication services to the electronic device.

[0153] In the embodiment of the present application, the fourth secondary cell is at least part of the secondary cells in the second secondary cell. When the fourth secondary cell is part of the secondary cell in the second secondary cell, after the electronic device deactivates the fourth secondary cell, the secondary cells in the second secondary cell other than the fourth secondary cell remain activated or remain in an activated state.

[0154] It can be understood that after the electronic device deactivates the above-mentioned fourth secondary cell and activates the above-mentioned fifth secondary cell, the electronic device can perform carrier aggregation on the main cell of the electronic device, the secondary cells in the above-mentioned second secondary cell except the fourth secondary cell, and the carriers of the fifth secondary cell, and perform communication services based on the CA carrier.

[0155] It can be understood that the number of secondary cells activated and deactivated by the electronic device is determined by the number of secondary cells supported by the electronic device.

[0156] In this way, when the network device configures a secondary cell list including cell mark information and information of the first secondary cell for the electronic device, after the electronic device activates the second secondary cell corresponding to the cell mark information in the first secondary cell, if the communication service of the electronic device becomes abnormal again, the electronic device can perform cell measurement on the first secondary cell configured in the secondary cell list, and re-select a suitable secondary cell in the first secondary cell for activation based on the CA parameters obtained by the measurement, and deactivate the secondary cell with degraded CA parameters in the activated secondary cell. In this way, since the electronic device can autonomously reactivate the suitable secondary cell through cell measurement without re-requesting the secondary cell from the network device, the operation process of the electronic device activating the secondary cell can be improved and signaling overhead can be saved.

[0157] Optionally, after step 208, if the electronic device's communication service is still in an abnormal state, the electronic device may report the electronic device's current required network resource parameters and signal status parameters, as well as the electronic device's capability information, to the network device, requesting the network device to reconfigure a more suitable secondary cell for the electronic device. For example, the electronic device may repeatedly perform steps 201 to 205. To avoid repetition, these steps are not described here.

[0158] Optionally, before step 201, the electronic device may first select a CA cell within the coverage area of ​​the network device for access, complete the network attachment process, and establish an initial connection. It will be appreciated that after the electronic device establishes a connection with the CA cell, the CA cell becomes the primary serving cell (Pcell) of the electronic device, also referred to as the primary cell. In other words, the primary cell of the electronic device is a cell with CA capabilities.

[0159] Exemplarily, the electronic device selects a CA cell to access, completes a network attachment process on the Pcell, and establishes an initial connection.

[0160] The Pcell refers to the cell where the UE electronic device resides, that is, the primary serving cell or primary cell.

[0161] The primary cell of the electronic device may be used to be responsible for RRC communication between the network device and the electronic device.

[0162] Optionally, the electronic device sending the first message to the network device may include: the electronic device sending the first message to the network device via the primary cell. The network device sends the secondary cell list to the electronic device.

[0163] Optionally, the Scell ​​of the electronic device may be added during RRC reconfiguration, and is used to provide additional radio resources for the electronic device.

[0165] Step 301: An electronic device sends a first message to a network device. The first message is used to request a secondary cell for performing a communication service.

[0171] Optionally, the abnormality in the communication service of the electronic device includes at least one of the following:

[0172] The data packets to be transmitted are blocked;

[0173] The packet loss rate of the data packet is greater than or equal to the packet loss rate threshold;

[0174] The number of data packets to be transmitted is greater than or equal to the maximum transmission number of the cell to which the electronic device is currently connected.

[0175] Optionally, the above step 303 may include the following step 303a or step 303b.

[0176] Step 303a: When the secondary cell list does not include cell mark information, the electronic device activates all secondary cells in the first secondary cell.

[0177] Step 303b: When the secondary cell list includes cell mark information, the electronic device activates a second secondary cell in the first secondary cell that corresponds to the cell mark information.

[0178] The second secondary cell is part of the first secondary cell. The cell marker information is used to indicate that the CA parameters of the second secondary cell meet the first condition.

[0179] Optionally, the CA parameters of the second secondary cell satisfy the first condition, including:

[0180] In a case where the second secondary cell includes L secondary cells, a sum of CA parameters of the L secondary cells satisfies the first condition, where L is an integer greater than 1;

[0181] In a case where the second secondary cell includes one secondary cell, the CA parameter of the one secondary cell satisfies the first condition.

[0182] Optionally, the sum of the CA parameters of the L secondary cells satisfies the first condition, which may include:

[0183] The degree of matching between the sum of the CA parameters of the L secondary cells and the first CA parameter is greater than or equal to a first threshold; or the degree of matching between the sum of the CA parameters of the L secondary cells and the first CA parameter is a maximum degree of matching in a first matching set, where the first matching set includes a degree of matching between at least one second CA parameter and the first CA parameter, each second CA parameter being a sum of CA parameters of L third secondary cells in the first secondary cell;

[0184] Optionally, the CA parameters of the secondary cell satisfying the first condition may include:

[0185] A matching degree between the CA parameters of the one secondary cell and the first CA parameters is greater than or equal to a first threshold; or, a matching degree between the CA parameters of the one secondary cell and the first CA parameters is a maximum matching degree in a second matching degree set, where the second matching degree set includes matching degrees between the CA parameters of each secondary cell in the first secondary cell and the first CA parameters.

[0187] Step 304: When an abnormality occurs in the communication service of the electronic device, the electronic device performs cell measurement on the first secondary cell to obtain a CA parameter of the first secondary cell.

[0188] Step 305: The electronic device deactivates the fourth secondary cell and activates the fifth secondary cell according to the CA parameters of the first secondary cell.

[0189] The fourth secondary cell is a secondary cell in the second secondary cell whose CA parameter is less than or equal to the second threshold; and the fifth secondary cell is a secondary cell in the first secondary cell other than the second secondary cell and whose CA parameter is greater than the second threshold.
