Description

Carrier aggregation capability reporting method and electronic device

[0001] The present application claims priority from the Chinese patent application No. 202410869063.4 filed on June 28, 2024, and entitled "Carrier aggregation capability reporting method and electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the technical field of electronic devices, and in particular to a carrier aggregation capability reporting method and an electronic device. BACKGROUND

[0003] Currently, in the process of network interaction between a user equipment (UE) and a network device, the UE needs to provide the network device with a carrier aggregation (CA) combination supported by the UE, so that the network device can configure a CA combination for the UE according to the CA combination reported by the UE, and the UE performs data transmission based on the configured CA combination.

[0004] For example, taking a base station A corresponding to the UE and an operator A as an example, the UE can report a CA combination supported by both the operator A and the UE to the base station A. Alternatively, the UE can report a CA combination supported by the UE to the base station A based on a preset number.

[0005] In some implementations, the base station A does not support the CA combination reported by the UE. Then, the base station A will not configure a CA combination for the UE, resulting in a communication lag problem in the UE. SUMMARY

[0006] Embodiments of the present application provide a carrier aggregation capability reporting method and an electronic device, so that the electronic device can report a CA combination supported by the electronic device to a base station side based on a current network situation. Then, the possibility of configuring a CA combination for the electronic device by the base station side is improved, and the problem of communication lag in the electronic device is avoided.

[0007] To achieve the above object, embodiments of the present application adopt the following technical solutions:

[0008] In a first aspect, a method for reporting carrier aggregation (CA) capability is provided. The method is applied to an electronic device. The method comprises: obtaining target frequency bands supported by a first operator. The target frequency bands are obtained based on a camping status of the electronic device. The first operator is an operator corresponding to a network accessed by the electronic device. Obtaining CA combinations supported by the electronic device. Generating first CA capability information. The first CA capability information comprises at least one first CA combination. The corresponding frequency bands in the first CA combination are included in the target frequency bands supported by the first operator, and the first CA combination is included in the CA combinations supported by the electronic device. Transmitting the first CA capability information to a network device of the first operator.

[0009] Based on the above scheme, the electronic device can obtain at least one first CA combination according to the target frequency bands supported by the first operator and the CA combinations supported by the electronic device, and transmit the at least one first CA combination to the network device of the first operator. The target frequency bands supported by the first operator are obtained based on the camping status of the device, which matches the real-time situation of the existing network. That is, the target frequency bands supported by the first operator can be the frequency bands in which the device camps in the existing network. Therefore, the target frequency bands supported by the first operator are also supported by the network device of the first operator. Thus, the network device of the first operator also supports the first CA combination with a high probability. Further, after the electronic device transmits the first CA combination, the possibility of the network device of the first operator configuring the CA combination for the electronic device can be improved, thereby avoiding the problem of communication lag in the UE.

[0010] Optionally, before generating the first CA capability information, the method further comprises: obtaining the CA combinations supported by the first operator from second CA capability information. The second CA capability information is pre-configured in the electronic device, and the second CA capability information is used to indicate CA combinations supported by multiple operators. The first CA capability information further comprises at least one second CA combination. The second CA combination is a common CA combination of the CA combinations supported by the first operator and the CA combinations supported by the electronic device. The second CA combination is different from the first CA combination.

[0011] Based on the above scheme, the electronic device can further report at least one second CA combination to the network device of the first operator. The second CA combination is a common CA combination supported by the electronic device and the first operator. Thus, the electronic device can sufficiently report the CA combinations supported by the electronic device, further increasing the possibility of the network device of the first operator configuring the CA combination for the electronic device.

[0012] Optionally, the target frequency band is a frequency band in the frequency bands supported by the first operator, in which the number of users that have camped on the device is relatively large. For example, the target frequency band can be a frequency band in the frequency bands supported by the first operator, in which the number of users that have camped on the device exceeds a first preset threshold.

[0013] Optionally, the frequency bands supported by the first operator are obtained from operator frequency band information. The operator frequency band information is preconfigured in the electronic device, and is used to indicate the frequency bands supported by multiple operators. The first operator is an operator corresponding to a network accessed by the electronic device. The carrier aggregation (CA) combinations supported by the electronic device are obtained. First CA capability information is determined. The first CA capability information further includes at least one third CA combination. The corresponding frequency bands in the third CA combination are included in the frequency bands supported by the first operator, and the third CA combination is included in the CA combinations supported by the electronic device. The first CA capability information is sent to a network device of the network of the first operator.

[0014] Based on the above scheme, the electronic device can further report at least one third CA combination to the network device of the network of the first operator. The corresponding frequency bands in the third CA combination are included in the frequency bands supported by the first operator, and the third CA combination is a CA combination supported by the electronic device. Therefore, the electronic device can more fully report the CA combinations supported by the electronic device, and further increase the possibility that the network device of the first operator configures the CA combinations for the electronic device.

[0015] Optionally, the target frequency band is obtained based on the camping of the device, including: the target frequency band is obtained based on a frequency band in the frequency bands supported by the first operator, in which the number of users that have camped on the device exceeds a first preset threshold. Therefore, the target frequency band supported by the first operator is further matched with the real-time situation of the network.

[0016] Optionally, before the first CA capability information is generated, the method further includes: obtaining, from the CA combinations supported by the electronic device, at least one first CA combination in which the corresponding frequency bands are included in the target frequency bands supported by the first operator, in a descending order of the number of users that have camped on the device corresponding to the target frequency bands supported by the first operator. Therefore, the electronic device can obtain the first CA combination based on the camping of the device.

[0017] Optionally, the number of the first CA combinations in the first CA capability information is N, and the number of the second CA combinations in the first CA capability information is M. N is a positive integer, and M is an integer greater than or equal to 0. The sum of N and M is equal to a second preset threshold.

[0018] Optionally, after the first CA capability information is determined, the method further includes: storing the first CA capability information. In this way, the first CA capability information can be obtained by the electronic device when the electronic device uses the first CA capability information in the future.

[0019] Optionally, the sending of the first CA capability information to the network device of the first operator includes: sending the first CA capability information to the network device of the first operator when a UE capability query message is received.

[0020] Optionally, before the target frequency band supported by the first operator is obtained, the method further includes: receiving camping information sent by a cloud server. The camping information is used to represent a camping situation of a device obtained by the cloud server in a first time period. The camping information includes a camping frequency band, and an operator identifier and a user identifier corresponding to the camping frequency band. A camping frequency band, for which a number of users whose devices camp on the camping frequency band exceeds a first preset threshold, is determined as the target frequency band according to the first operator identifier corresponding to the camping frequency band.

[0021] Based on the above scheme, the electronic device can obtain the target frequency band supported by the first operator according to the camping information. The camping information includes a frequency band in which the device is currently camping. In this way, the target frequency band supported by the first operator obtained by the electronic device matches the real-time situation of the existing network. Therefore, the possibility that the network device of the first operator supports the first CA combination can be improved.

[0022] Optionally, the electronic device is configured with a plurality of target frequency bands supported by operators; and the target frequency band supported by the first operator corresponds to an identifier of the first operator. The obtaining of the target frequency band supported by the first operator includes: obtaining the identifier of the first operator; and obtaining, from the operator frequency band table, the target frequency band supported by the first operator according to the identifier of the first operator.

[0023] In the present application, the operator frequency band information includes a plurality of target frequency bands supported by operators. Therefore, based on the above scheme, the electronic device can obtain the target frequency band supported by the first operator from the electronic device according to the identifier of the first operator.

[0024] Optionally, the obtaining of the carrier aggregation (CA) combination supported by the electronic device includes: obtaining the CA combination supported by the electronic device from fourth CA capability information. The fourth CA capability information is pre-configured in the electronic device, and the fourth CA capability information is used to indicate the CA combination supported by the electronic device.

[0025] Optionally, the obtained identifier of the first operator includes: obtaining the identifier of the first operator when registering with the network of the first operator. Alternatively, the identifier of the first operator is obtained when accessing the network device of the first operator.

[0026] Optionally, the obtaining the CA combination supported by the first operator from the second CA capability information comprises: obtaining the CA combination supported by the first operator from the second CA capability information according to the identifier of the first operator.

[0027] In a second aspect, an electronic device is provided, which comprises a memory and one or more processors. The memory is coupled to the processor. The memory is configured to store computer program code comprising computer instructions, which, when executed by the processor, cause the electronic device to perform the carrier aggregation capability reporting method according to any one of the first aspect and the optional designs thereof.

[0029] In a fourth aspect, a chip system is provided, which comprises a processor and a communication interface.

[0048] Hereinafter, the terms "first" and "second" are used only for the purpose of description and should not be construed as indicating or implying relative importance or implying the number of the technical features indicated. Thus, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0049] The technical solutions provided in the present application can be applied to various communication systems, for example, a long term evolution (LTE) system, a long term evolution advanced (LTE-A) system, a worldwide interoperability for microwave access (WiMAX) system, a new radio (NR) system of 5th generation mobile communication technology (5G), a system of mixed networking of LTE and NR, a 6th generation mobile network (6G) system, and other next-generation communication systems, etc. Alternatively, the communication system can also be a non-3GPP communication system, which is not limited. The terms "network" and "system" can be replaced with each other.

[0050] Among them, the above-mentioned communication system applicable to the present application is only an example, and the communication system applicable to the present application is not limited thereto. Herein, it is uniformly described that the following will not be described in detail.

[0051] Referring to FIG. 1, an exemplary communication system provided by an embodiment of the present application is shown. As shown in FIG. 1, the communication system includes a UE and a network device. A communication connection can be established between the UE and the network device.

[0052] In an embodiment of the present application, the network device can be a base station (BS), or the network device can be a device that communicates with the UE or other communication stations such as a relay station, and the network device can provide communication coverage for a specific physical area. For example, the network device can be an evolved node B (eNB or eNodeB) in LTE-A; it can also be a next generation node B (gNB) in 5G NR; or it can also be other network devices that provide access services in future wireless communication networks, which are not limited by the present application.

[0053] The communication system related to the embodiments of the present application can perform data transmission of down link (DL) and / or up link (UL) through carrier aggregation (CA). Among them, CA refers to aggregating several component carriers (CCs) together to achieve a larger transmission bandwidth, thereby effectively improving the uplink and downlink transmission rate.

[0054] For example, a scenario after aggregation of a plurality of carriers is shown in FIG. 2. The plurality of carriers can include CC1, CC2, and CCn, etc. The plurality of carriers can be contiguous carriers, or can be discrete carriers (including intra-band discrete carriers and inter-band discrete carriers).

[0055] The following describes the embodiments of the present application by taking a UE as a mobile phone 100 and a network device as a base station A as an example.

[0056] Referring to FIG. 3, FIG. 3 shows a flow diagram of a CA capability reporting method. In FIG. 3, the CA combinations supported by an operator can be preset in the UE as common capabilities. The UE can determine a common CA combination supported by both the UE and the operator according to the CA combinations supported by the UE. The UE can report the common CA combination to the network device, so as to facilitate the network device to subsequently configure a CA combination for the UE according to the common CA combination.

[0057] The operator in the embodiments of the present application can be an operator in any region of the world. For example, the operator can include any one of China Mobile (CMCC), China Union (CUCC), China Telecom (CT), or Telkom Indonesia, etc.

[0058] As shown in FIG. 3, the scheme includes:

[0059] S301, the UE obtains an identifier 1 corresponding to an operator A when starting up.

[0060] For example, the UE can obtain the identifier 1 corresponding to the operator A when registering to the network of the operator A, or when accessing the base station A of the operator A.

[0061] In some implementations, the operator identity can be a PLMN of the operator. Wherein, the PLMN is composed of an MCC and a Mobile Network Code (MNC) of the region where the operator is located. Wherein, the MCC is uniformly allocated and managed by the International Telecom Union (ITU) worldwide, and is used to uniquely identify different regions in the global system for mobile communications, with a total of 3 digits. For example, the MCC of China is 460. The MNC is usually composed of 2-3 digits. The MNCs of different operators are different, and the MNCs of different modes of mobile networks of the same operator are also different. For example, the GSM system of China Unicom uses 01, and the GSM system of China Mobile uses 00.

[0062] For example, the identity 1 can be a PLMN corresponding to the operator A.

[0063] S302, the UE is pre-configured with the CA capability table 1 and the CA capability table 2.

[0064] In the present application, the UE can be pre-configured with CA capability information 1, which is used to indicate the supported CA combinations of multiple operators and the CA combinations supported by the UE itself. In some embodiments of the present application, the CA capability table 1 can also be referred to as the second CA capability information. The CA capability table 2 can also be referred to as the fourth CA capability information.

[0065] For example, the CA capability information 1 can include the CA capability table 1 and the CA capability table 2. Wherein, the CA capability table 1 includes the supported CA combinations of multiple operators, and the CA capability table 2 includes the CA combinations supported by the UE itself.

[0066] As a specific implementation, referring to Table 1, an example of multiple operator-supported CA combinations pre-configured for the UE. As shown in Table 1, the UE is configured with the identity 1 corresponding to the operator A and the CA combinations supported by the operator A: CA1, CA2, CA4 and CA6, the identity 2 corresponding to the operator B and the CA combinations supported by the operator B: CA1, CA3, CA4 and CA7, and the identity 2 corresponding to the operator C and the CA combinations supported by the operator C: CA1, CA4 and CA8.

[0067] Table 1

[0068] In some implementations, similar to the identity 1, the identity 2 can be a PLMN corresponding to the operator B, and the identity 3 can be a PLMN corresponding to the operator C.

[0069] In addition, in this application, the operator identifier can also be used to identify the CA combination supported by the operator. For example, identifier 1 can be used to identify the CA combination supported by operator A, identifier 2 can be used to identify the CA combination supported by operator B, and identifier 3 can be used to identify the CA combination supported by operator C.

[0070] Referring to Table 2, an example of the CA combination supported by the UE itself is pre-configured. As shown in Table 2, the CA combination supported by the UE itself can include CA1, CA2, CA3, CA4, and CA8.

[0071] Table 2

[0072] It should be noted that in the description of Table 1 and Table 2, the CA combination supported by multiple operators and the CA combination supported by the UE itself are only an example. Embodiments of the present application do not make any limitation on the CA combination supported by multiple operators and the CA combination supported by the UE itself.

[0073] S303, the UE finds the CA combination set 1 supported by operator A according to identifier 1 and CA capability table 1.

[0074] For example, after obtaining the identifier 1 corresponding to operator A, the UE can find the CA combination supported by operator A from the pre-configured CA capability table 1 according to the identifier 1.

[0075] For example, the CA combination supported by operator A is included in the CA combination set 1. As shown in Table 1, the CA combination set 1 can include CA1, CA2, CA4, and CA6.

[0076] S304, the UE obtains the CA combination set 2 supported by the UE according to CA capability table 2.

[0077] In this application, the UE can also obtain the CA combination supported by the UE according to the pre-configured CA capability table 2 when starting up.

[0078] For example, the CA combination supported by the UE is included in the CA combination set 2. As shown in Table 2, the CA combination set 2 can include CA1, CA2, CA3, CA4, and CA8.

[0079] S305, the UE determines the common CA combination set 3 according to the CA combination set 1 supported by operator A and the CA combination set 2 supported by the UE.

[0080] For example, the common CA combination set 3 is used to indicate the common CA combination supported by operator A and the UE itself. The UE can determine the common CA combination set 3 according to the CA combination set 1 in S303 and the CA combination set 2 in S304.

[0081] For example, referring to FIG. 4, the CA combinations supported by the operator A are all included in the CA combination set 1, which includes CA1, CA2, CA4 and CA6. The CA combinations supported by the UE are all included in the CA combination set 2, which includes CA1, CA2, CA3, CA4 and CA8. Then the UE can determine the common CA combination set 3 including the CA combinations supported by the UE and supported by the operator A, i.e. the intersection of {CA1, CA2, CA4, CA6} and {CA1, CA2, CA3, CA4, CA8} in the common CA combination set 3. As shown in FIG. 4, the common CA combination set 3 includes CA1, CA2 and CA4.

[0082] S306, the UE stores the common CA combination set 3.

[0083] For example, after obtaining the common CA combination set 3, the UE can store the common CA combination set 3. In this way, when the UE uses the common CA combination set 3 later, the UE can obtain the common CA combination set 3 from the storage.

[0084] S307, the UE sends the common CA combination set 3 to the base station A when receiving the UE capability query message.

[0085] In the embodiments of the present application, the UE can send the common CA combination set 3 to the base station A.

[0086] For example, the UE can send the common CA combination set 3 to the base station A when receiving the UE capability query message. The UE capability query message can be sent by the base station A.

[0087] Correspondingly, the base station A can receive the common CA combination set 3, and then configure the CA combination according to the CA combinations indicated in the common CA combination set 3.

[0088] In some implementations, the base station A supports at least one CA combination in the common CA combination set 3. In this implementation, the base station A can configure the CA combination in the common CA combination set 3 which is also supported by the base station A for the UE. In this way, the UE can use the newly configured CA combination for data transmission and reception later.

[0089] For example, assuming that the base station A supports CA1 and CA2 in the common CA combination set 3, the base station A can configure CA1 or CA2 for the UE after receiving the common CA combination set 3 reported by the UE. In this way, the UE can use CA1 or CA2 for data transmission and reception later.

[0090] In other implementations, the base station A does not support the CA combinations included in the common CA combination set 3.

[0091] For example, the base station A does not support the corresponding frequency band in the public CA combination set 3. Alternatively, the base station A does not support the CA combinations (such as CA1, CA2 and CA4) in the public CA combination set 3.

[0092] In this implementation, after receiving the public CA combination set 3 reported by the UE, the base station A will not configure the CA combination for the UE.

[0093] At this time, the UE can only perform data transmission and reception on one carrier unit, resulting in communication lag in the UE.

[0094] In some other embodiments, the UE is not configured with the CA combination supported by the operator A. In this embodiment, the UE can directly report the CA combination supported by the UE to the base station A. That is, the UE can directly report the CA combination set 2 to the base station A.

[0095] It should be noted that in some embodiments, the number of CA combinations reported by the UE cannot exceed a preset threshold 1. For example, assuming that the preset threshold 1 is 128, the UE can report at most 128 CA combinations. In some other embodiments of the present application, the preset threshold 1 can also be referred to as a second preset threshold.

[0096] In yet some other implementations, the base station A does not support the CA combinations included in the CA combination set 2.

[0097] In this implementation, after receiving the CA combination set 2 reported by the UE, the base station A will not configure the CA combination for the UE. In this case, the UE will also have the problem of communication lag.

[0098] To solve the above problems, the present application provides a carrier aggregation capability reporting method and an electronic device. Based on the method, when the electronic device registers with the network corresponding to the operator A or accesses the base station A of the operator A, the electronic device can obtain the target frequency band supported by the operator A from the operator frequency band information. The target frequency band is obtained based on the camping status of the device. The electronic device can also obtain the CA combinations supported by the device. The electronic device can generate at least one target CA combination according to the target frequency band supported by the operator A and the CA combinations supported by the electronic device. The target CA combination corresponds to a frequency band included in the target frequency band supported by the operator A, and the target CA combination is included in the CA combinations supported by the electronic device. When the electronic device receives a UE capability query message, the electronic device can send the at least one target CA combination to the base station A.

[0099] Correspondingly, the base station A can configure the CA combination for the electronic device based on the at least one target CA combination reported by the electronic device.

[0100] Since the target frequency band supported by the operator A is obtained based on the device camping situation, it matches the real-time situation of the live network. That is, the target frequency band supported by the operator A is a frequency band in which a device camps in the live network. Therefore, the target frequency band supported by the operator A is also supported by the base station A. Thus, the base station A also supports the target CA combination with a large probability. Further, the UE reports the at least one target CA combination, thereby improving the possibility that the base station A configures the CA combination for the UE, and thereby avoiding the problem of communication lag in the UE.

[0101] In some other embodiments of the present application, the target CA combination can also be referred to as a first CA combination. The operator A can also be referred to as a first operator.

[0102] The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0103] It should be noted that the scheme provided by the embodiments of the present application can be applied to a UE having a communication function.

[0104] In some other embodiments of the present application, the UE can also be replaced by any other electronic device having a communication function. The electronic device can also be referred to as a terminal device or a terminal.

[0110] The processor 510 can also be provided with a memory for saving instructions and data. In some embodiments, the memory in the processor 510 can be a cache memory. The memory can save instructions or data that the processor 510 has used or used frequently. If the processor 510 needs to use the instructions or data, it can be directly called from the memory. Avoid repeated access and reduce the waiting time of the processor 510, thus improving the efficiency of the system.

The program area can save an operating system, at least one application required by a function (such as a sound playing function, an image playing function, etc.), etc. The data area can save data created during the use of the electronic device 500 (such as audio data, a phonebook, etc.), etc. In addition, the internal memory 521 can include a high-speed random access memory, and can also include a non-volatile memory, for example, at least one magnetic disk storage device, a flash memory device, a universal flash memory (UFS), etc. The processor 510 executes various function methods or data processing of the electronic device 500 by running the instructions saved in the internal memory 521 and / or the instructions saved in the memory provided in the processor.

[0112] The modem processor can include a modulator and a demodulator. The modulator is configured to modulate a low frequency baseband signal to be transmitted into a medium-high frequency signal. The demodulator is configured to demodulate a received electromagnetic wave signal into a low frequency baseband signal. The demodulator then transmits the demodulated low frequency baseband signal to the baseband processor for processing. The low frequency baseband signal is transmitted to the application processor after being processed by the baseband processor. In some embodiments, the modem processor can be a separate device. In other embodiments, the modem processor can be independent of the processor 510, and can be disposed in the same device as the mobile communication module 550 or other functional modules.

[0113] In embodiments of the present application, the UE can obtain at least one target CA combination through the modem processor when it is powered on. The target CA combination corresponds to a frequency band included in the target frequency band supported by the operator A, and the target CA combination is a CA combination supported by the UE itself. The target frequency band supported by the operator A is obtained based on the camping status of the device. When the UE receives the UE capability query message of the base station A, it can report the at least one target CA combination to the base station A. So that the base station A can configure the CA combination for the UE according to the at least one target CA combination reported by the UE.

[0114] In addition, the operator A can be the operator registered by the UE when it is powered on, or the operator corresponding to the accessed base station A.

[0115] In the present application, the UE can be pre-configured with a plurality of target frequency bands supported by operators. The target frequency band supported by the operator is dynamically changed. For example, it can be periodically configured or updated. The target frequency band supported by the operator matches the current network situation within a preset time period. For example, the target frequency band supported by the operator can be related to the device camping status in the current network within a preset time period.

[0116] The implementation of the UE pre-configuring a plurality of target frequency bands supported by operators will be described below in combination with specific embodiments.

[0117] For example, referring to Table 3, an example of a plurality of target frequency bands supported by operators pre-configured for the UE. The UE can configure a plurality of target frequency bands supported by operators in the form of operator frequency band table 3. The operator frequency band table 3 includes the operator identifier corresponding to the operator and the target frequency band supported by the operator. The target frequency band supported by the operator is obtained based on the device camping status in the current network within a preset time period.

[0118] In other embodiments of the present application, the preset threshold 2 can also be referred to as a first preset threshold.

[0119] As shown in Table 3, the operator frequency band table 3 includes an identifier 1 corresponding to operator A and target frequency bands supported by operator A: F1, F2, F3 and F4, an identifier 2 corresponding to operator B and target frequency bands supported by operator B: F1, F3, F4 and F5, and an identifier 2 corresponding to operator C and target frequency bands supported by operator C: F1, F4 and F6.

[0120] In some embodiments of the present application, the identifier 1 can also be referred to as a first identifier.

[0121] Table 3

[0122] In addition, in some embodiments of the present application, in the target frequency bands supported by operator A, the number of users corresponding to the residence in the time period T1 decreases in turn for F1, F2, F3 and F4. Similarly, in the target frequency bands supported by operator B, the number of users corresponding to the residence in the time period T1 also decreases in turn for F1, F3, F4 and F5. In the target frequency bands supported by operator C, the number of users corresponding to the residence in the time period T1 decreases in turn for F1, F4 and F6.

[0123] In some embodiments of the present application, the time period T1 can also be referred to as a first time period.

[0124] It should be noted that in the description of Table 3, the target frequency bands supported by multiple operators are only an example. The embodiments of the present application do not make any limitation on the target frequency bands supported by multiple operators.

[0125] In the embodiments of the present application, the UE can configure the operator frequency band table 3 according to the residence information collected by the cloud service. The residence information is used to indicate the frequency band usage of multiple operators.

[0126] For example, referring to FIG. 6, after obtaining the residence information, the cloud server can send the residence information to the UE. The UE can configure the operator frequency band table 3 according to the residence information.

[0127] As shown in FIG. 6, the scheme includes:

[0128] S601, the cloud server receives the residence information sent by multiple terminals.

[0129] In the embodiments of the present application, the cloud server can receive the residence information sent by multiple terminals in the time period T1. The residence information includes a residence frequency band, and an operator identifier and a user identifier corresponding to the residence frequency band. The residence frequency band corresponds to the frequency band in which the multiple terminals have resided in the time period T1. The user identifier is used to identify different mobile communication users.

[0130] For example, the user identifier can include an International Mobile Subscriber Identity (IMSI) or an International Mobile Equipment Identity (IMEI).

[0131] S602, the cloud server sends the camping information to the UE.

[0132] For example, after obtaining the camping information, the cloud server can send the camping information to the UE.

[0133] It can be understood that the camping information collected by the cloud server can change. In some embodiments of the present application, the cloud server can update the camping information and send the updated camping information to the UE according to a preset period T2.

[0134] S603, the UE configures the operator frequency band table 3 according to the camping information.

[0135] It can be understood that the camping frequency band is included in the operator supported frequency band. Therefore, in the embodiments of the present application, the UE can configure the plurality of operator supported target frequency bands according to the camping information.

[0136] For example, the UE can include the camping frequency band in the corresponding operator supported target frequency band according to the operator identifier corresponding to the camping frequency band. The operator supported target frequency band corresponds to the camping frequency band whose number of camping users exceeds the preset threshold 2.

[0137] For example, taking the camping frequency band F1 and the operator identifier corresponding to F1 as identifier 1, the UE can include the frequency band F1 in the target frequency band supported by operator A. The number of users camping on F1 exceeds the preset threshold 2.

[0138] In some embodiments of the present application, the UE can also sort each operator supported target frequency band in descending order of the number of camping users according to the user identifier corresponding to each camping frequency band.

[0139] For example, the UE can obtain that the target frequency band supported by operator A includes F2, F1, F4 and F3 according to the operator identifier corresponding to the camping frequency band. The frequency band F2 corresponds to P2 user identifiers, the frequency band F1 corresponds to P1 user identifiers, the frequency band F4 corresponds to P4 user identifiers, and the frequency band F3 corresponds to P3 user identifiers. Assuming that P1, P2, P3 and P4 decrease in turn, the target frequency band supported by operator A is F1, F2, F3 and F4 in turn.

[0140] In some implementations, the UE can configure a plurality of target bands supported by an operator in the form of the operator band table 3, and store the operator band table 3 in the memory. Detailed description about the operator band table 3 can refer to the description in the table 3, which will not be repeated here.

[0141] It should be noted that in the description of FIG. 6, the UE is taken as an example to configure the operator band table 3 according to the camping information. In some other embodiments of the present application, the cloud server can configure the operator band table 3 according to the collected camping information. The UE can periodically obtain the operator band table 3 from the cloud server.

[0142] For example, the cloud server can send the operator band table 3 to the UE according to the preset period T3 after configuring the operator band table 3.

[0143] The implementation of the cloud server configuring the operator band table 3 according to the camping information is similar to the implementation of the UE configuring the operator band table 3 according to the camping information, and the specific content can refer to the related description in S603, which will not be repeated here.

[0144] Correspondingly, after receiving the operator band table 3, the UE can store the operator band table 3.

[0145] It should be noted that when storing the newly received operator band table 3, the UE can overwrite the previously stored operator band table 3.

[0146] It can be understood that since the camping information collected by the cloud server will change, the operator service table 3 configured by the cloud server according to the collected camping information can also change accordingly.

[0147] In some other embodiments of the present application, in addition to including the operator identifier corresponding to the operator and the target bands supported by the operator, the operator band table 3 can also include the version information of the operator supported band. The version information is used to indicate the version of the pre-configured target band supported by the operator.

[0148] For example, referring to table 4, table 4 shows another example of the operator band table 3. In table 4, the operator band table 3 includes the operator identifier, the target bands supported by the operator, and the version information of the target bands supported by the operator. In table 4, all the target bands supported by the operator can correspond to one version information.

[0149] Table 4

[0150] For another example, referring to Table 5, Table 5 shows another example of the operator frequency band table 3. In Table 5, each target frequency band supported by each operator is configured with a version information. The version information of each target frequency band supported by each operator can be the same or different.

[0151] Table 5

[0152] Thus, according to the version information shown in Table 4 or Table 5, the UE can acquire the target frequency band supported by the operator corresponding to the latest version from the cloud server, and update the target frequency band supported by the operator pre-configured in the UE.

[0153] As an example, the UE can query the latest version information of the operator frequency band table 3 from the cloud server according to a preset period T4. The UE can determine whether to acquire the latest version of the operator frequency band table 3 from the cloud server according to whether the queried latest version information is consistent with the version information of the operator frequency band table 3 stored in the UE.

[0154] For example, when the latest version information is inconsistent with the version information of the operator frequency band table 3 stored in the UE, it indicates that the operator frequency band table 3 stored in the UE is not the latest version. At this time, the UE can acquire the operator frequency band table 3 corresponding to the latest version from the cloud server.

[0155] For another example, when the latest version information is consistent with the version information of the operator frequency band table 3 stored in the UE, it indicates that the operator frequency band table 3 stored in the UE is the latest version. At this time, the UE will not acquire the operator frequency band table 3 corresponding to the latest version from the cloud server.

[0156] Since querying the latest version information of the operator frequency band table 3 and / or acquiring the operator frequency band table 3 corresponding to the latest version requires a large amount of data interaction. Therefore, in a possible implementation, the UE can query the latest version information and / or acquire the operator frequency band table 3 corresponding to the latest version by default when connecting to the WLAN.

[0157] Alternatively, the UE can query the latest version information of the operator frequency band table 3 and / or acquire the operator frequency band table 3 corresponding to the latest version when the wireless network coverage is good.

[0158] Further, it can avoid generating excessive traffic fees in the UE.

[0159] In some embodiments of the present application, the UE can be preconfigured with the CA capability table 2 and the operator frequency band table 3. The UE can obtain the CA combinations supported by the UE itself from the CA capability table 2, and obtain the target frequency bands supported by the operator A from the operator frequency band table 3. The UE can determine the target CA combinations according to the CA combinations supported by the UE itself and the target frequency bands supported by the operator A. The target CA combinations correspond to frequency bands included in the target frequency bands supported by the operator A, and the target CA combinations are the CA combinations supported by the UE.

[0160] In combination with the description in FIG. 6, the target frequency bands supported by the operator A in the operator frequency band table 3 are the frequency bands in which the user has resided in real time. That is, in the case of the existing network, the target frequency bands supported by the operator A are also supported by the base station A. Therefore, for the target CA combinations determined according to the CA combinations supported by the UE itself and the target frequency bands supported by the operator A, the base station A also supports them with a relatively high probability.

[0161] In this embodiment, the UE can include the target CA combinations in the CA combination set 5. The UE can determine the CA capability information 2 that can be reported to the base station A according to the CA combination set 5. The CA capability information 2 includes at least one target CA combination in the CA combination set 5.

[0162] For example, referring to FIG. 7, the UE can determine the CA combination set 2 supported by the UE itself and the frequency band set 4 supported by the operator A when the UE is powered on. The UE can obtain the target CA combination set 5 according to the frequency band set 4 and the CA combination set 2. The UE can determine the CA combination set 6 according to the target CA combination set 5. The CA combination set 6 includes at least one target CA combination in the target CA combination set 5. When the UE receives the UE capability query message sent by the base station A, the UE can report the CA combination set 6 to the base station A in the UE capability information 92. So that the base station A can subsequently configure the CA combinations for the UE according to the CA combination set 6.

[0163] In some other embodiments of the present application, the CA combination set 6 can also be referred to as the first CA capability information. The CA combination set 5 can also be referred to as the third CA capability information.

[0164] As shown in FIG. 7, the scheme includes:

[0165] S701, the UE is powered on.

[0166] S702, the UE is preconfigured with the CA capability table 2.

[0167] S703, the UE obtains the CA combination set 2 supported by the UE according to the CA capability table 2.

[0168] S704, the UE obtains the identifier 1 corresponding to the operator A.

[0169] In the embodiments of the present application, the detailed description of S702 can refer to the description of S302 in FIG. 3. The implementation of S703 corresponds to S304 in FIG. 3, and the implementation of S704 corresponds to S301 in FIG. 3. The specific content can refer to the description of S304 and S301, which will not be repeated here.

[0170] S705, the UE is pre-configured with the operator frequency band table 3.

[0171] For example, in combination with the foregoing description, the operator frequency band table 3 includes a plurality of target frequency bands supported by the operator. The operator frequency band table 3 can be any one of the operator frequency band tables 3 shown in the examples of Table 3, Table 4 or Table 5.

[0172] The detailed description of the UE configuring the operator frequency band table 3 can refer to the description in FIG. 6, which will not be repeated here.

[0173] S706, the UE determines the frequency band set 4 supported by the operator A according to the identifier 1 and the operator frequency band table 3.

[0174] In the embodiments of the present application, the UE can also determine the frequency band set 4 supported by the operator A according to the identifier 1 and the operator frequency band table 3 when it is powered on.

[0175] For example, taking Table 3 as an example, the frequency band set 4 supported by the operator A can include F1, F2, F3 and F4.

[0176] S707, the UE determines the CA combination set 5 including the frequency band 1 according to the CA combination set 2, and the frequency band 1 is included in the frequency band set 4.

[0177] For example, after obtaining the frequency band set 4 supported by the operator A, the UE can find the target CA combination including the frequency band 1 from the CA combination set 2, and include the target CA combination in the CA combination set 5. The frequency band 1 is a target frequency band supported by the operator A, that is, the frequency band 1 is included in the frequency band set 4.

[0178] That is, each carrier unit in the target CA combination corresponds to a frequency band included in the frequency band set 4.

[0179] For example, as shown in FIG. 8, in the CA combination set 2, CA1 is CA_F1_F2, CA2 is CA_F1_F3, CA3 is CA_F4_F3, CA4 is CA_F1_F4, and CA8 is CA_F2_F4, that is, CA1 includes carrier aggregation of frequency band F1 and frequency band F2, CA2 includes carrier aggregation of frequency band F1 and frequency band F3, CA3 includes carrier aggregation of frequency band F4 and frequency band F3, CA4 includes carrier aggregation of frequency band F1 and frequency band F4, and CA8 includes carrier aggregation of frequency band F2 and frequency band F4. The frequency band 1 can include one of F1, F2, F3 or F4. Then, the UE determines the target CA combination in the CA combination set 5 according to the CA combination set 2, which can be one of CA1, CA2, CA3, CA4 or CA8.

[0180] In some embodiments of the present application, the UE can determine the CA combination including F1, the CA combination including F2, the CA combination including F3 and the CA combination including F4 in the CA combination set 2 in turn according to the order of the frequency bands in the frequency band set 4.

[0181] Therefore, the target CA combinations included in the CA combination set 5 can be CA1, CA2, CA4, CA8 and CA3 in turn.

[0182] S708, the UE determines the CA combination set 6 according to the CA combination set 5.

[0183] It should be noted that in the embodiments of the present application, the UE can only report the preset threshold 1 CA combination when feeding back the UE capability information to the base station A.

[0184] For example, the preset threshold 1 is equal to N1, and the CA combination set 6 includes N1 target CA combinations in the CA combination set 5.

[0185] For example, the CA combination set 6 can include the first N1 target CA combinations in the CA combination set 5.

[0186] As a specific example, referring to FIG. 8, assuming that N1 is equal to 5, the first 5 target CA combinations in the CA combination set 5 are included in the CA combination set 6. That is, the CA combination set 6 includes CA1, CA2, CA4, CA8 and CA3.

[0187] S709, the UE stores the CA combination set 6.

[0188] For example, after obtaining the CA combination set 6, the UE can first store the CA combination set 6. In order to facilitate the UE to obtain the CA combination set 6 from the memory in subsequent use of the CA combination set 6.

[0189] S710, the UE sends the CA combination set 6 to the base station A upon receiving the UE capability enquiry message.

[0190] For example, the UE can send the CA combination set 6 to the base station A upon receiving the UE capability enquiry message. The UE capability enquiry message can be sent by the base station A.

[0191] For example, referring to FIG. 9, the UE can send the CA combination set 6 to the base station A according to the interaction with the base station A in FIG. 9.

[0192] As shown in FIG. 9, the scheme includes:

[0193] S901, the base station A sends a UE capability enquiry message 91 to the UE.

[0194] For example, the base station A needs to obtain the CA capability information 2 in the UE before configuring the CA combination for the UE. In this example, the base station A can query the CA capability information 2 of the UE through the UE capability enquiry message 91.

[0195] For example, the UE capability enquiry message 91 includes UECapabilityEnquiry.

[0196] Correspondingly, the UE can receive the UE capability enquiry message 91.

[0197] In some embodiments of the present application, the UE capability enquiry message 91 can also be referred to as a UE capability enquiry message.

[0198] S902, the UE sends UE capability information 92 to the base station A, and the UE capability information 92 includes the CA combination set 6.

[0199] For example, the UE can obtain the CA combination set 6 from the memory and feed back the UE capability information 92 to the base station A after receiving the UE capability enquiry message 91. The UE capability information 92 includes the CA combination set 6.

[0200] For example, the UE capability information 92 includes UECapabilityInformation.

[0201] Correspondingly, the base station A can receive the CA combination set 6, and then configure the CA combination according to the CA combination indicated in the CA combination set 6.

[0202] In the example of FIG. 7, when the UE reports the UE capability information (such as the UE capability information 92) to the base station A, the UE can report N1 target CA combinations according to the CA combinations supported by the UE itself and the target frequency bands supported by the operator A by performing the scheme in FIG. 7. The target CA combinations are the CA combinations supported by the UE itself, and the frequency bands corresponding to the target CA combinations are all included in the target frequency bands supported by the operator.

[0203] Since the target frequency bands supported by the operator A are obtained based on the device camping situation. That is, the target frequency bands supported by the operator A are the frequency bands that the device has camped on in real time. Therefore, the target frequency bands supported by the operator A are also supported by the base station A. Thus, the base station A also supports the target CA combinations with a large probability. Further, the UE can improve the possibility that the base station A configures the CA combinations for the UE by reporting the N1 target CA combinations. Further, the problem of communication lag in the UE can be avoided.

[0204] In some other embodiments of the present application, the UE can be preconfigured with the CA capability table 1, the CA capability table 2, and the operator frequency band table 3. Wherein, the UE can obtain the CA combinations supported by the operator A from the CA capability table 1, obtain the CA combinations supported by the UE itself from the CA capability table 2, and obtain the target frequency bands supported by the operator A from the operator frequency band table 3.

[0205] In this embodiment, the UE can report at least one supplementary CA combination in addition to the common CA combination set 3 in FIG. 3. Wherein, the supplementary CA combination can be a target CA combination in the CA combination set in FIG. 7.

[0206] For example, referring to FIG. 10, the UE can determine the common CA combination set 3 supported by the UE itself and the operator A when the UE is powered on. Meanwhile, the UE can also obtain the CA combination set 5 according to the target frequency bands supported by the operator A and the CA combination set 2 supported by the UE itself. The UE can determine the CA combination set 7 according to the CA combination set 5 and the common CA combination set 3. Wherein, the CA combination set 7 includes at least one target CA combination in the CA combination set 5 and at least one CA combination in the common CA combination set 3. When the UE receives the UE capability query message sent by the base station A, the UE can report the CA combination set 7 to the base station A. So that the base station A can subsequently configure the CA combinations for the UE according to the CA combination set 7.

[0207] As shown in FIG. 10, the scheme includes:

[0208] S1001, the UE obtains the identifier 1 corresponding to the operator A when the UE is powered on.

[0209] S1002, the UE preconfigures the CA capability table 1 and the CA capability table 2.

[0210] S1003, the UE finds the CA combination set 1 supported by the operator A according to the identity 1 and the CA capability table 1.

[0211] For example, referring to FIG. 11, according to the CA capability table 1 as shown in table 1, the CA combination set 1 supported by the operator A can include CA1, CA2, CA4 and CA6.

[0212] S1004, the UE acquires the CA combination set 2 supported by the UE according to the CA capability table 2.

[0213] For example, referring to FIG. 11, according to the CA capability table 2 as shown in table 2, the CA combination set 2 supported by the UE can include CA1, CA2, CA3, CA4 and CA8.

[0214] S1005, the UE determines the common CA combination set 3 according to the CA combination set 1 supported by the operator A and the CA combination set 2 supported by the UE.

[0215] For example, the common CA combination set 3 includes at least one common CA combination in the CA combination set 1 and the CA combination set 2, that is, the common CA combination set 3 includes the intersection of {CA1, CA2, CA4, CA6} and {CA1, CA2, CA3, CA4, CA8}. As shown in FIG. 8, the common CA combination set 3 includes CA1, CA2 and CA4.

[0216] In the embodiments of the present application, the implementation of S1001 to S1005 can correspond to S301 to S305 in FIG. 3, and the specific content is referred to the description in S301 to S305, which will not be repeated here.

[0217] S1006, the UE pre-configures the operator frequency band table 3.

[0218] S1007, the UE determines the frequency band set 4 supported by the operator A according to the identity 1 and the operator frequency band table 3.

[0219] For example, referring to FIG. 11, taking table 3 as an example, the frequency band set 4 supported by the operator A can include F1, F2, F3 and F4.

[0220] S1008, the UE determines the CA combination set 5 including the frequency band 1 according to the CA combination set 2, the frequency band 1 being included in the frequency band set 4.

[0221] For example, as shown in FIG. 11, the UE determines that the CA combination set 5 can include CA1, CA2, CA4, CA8 and CA3 according to the CA combination set 2.

[0222] In embodiments of the present application, the implementation of S1006 to S1008 can correspond to S705 to S707 in FIG. 7, and the specific content refers to the description in S705 to S707, which will not be repeated here.

[0223] S1009, the UE determines the CA combination set 7 according to the public CA combination set 3 and the CA combination set 5.

[0224] In embodiments of the present application, after obtaining the public CA combination set 3 and the CA combination set 5, the UE can determine the CA combination set 7 according to the public CA combination set 3 and the CA combination set 5. Wherein, the CA combination set 7 includes the public CA combination set 3 and the CA combination set 5.

[0225] For example, assuming that the number of CA combinations included in the public CA combination set 3 is N2, the CA combination set 7 can include N2 CA combinations 1 and N3 target CA combinations. Wherein, the N2 CA combinations 1 are included in the public CA combination set 3, and the N3 target CA combinations are included in the CA combination set 5. The N2 CA combinations 1 are different from the N3 target CA combinations. N2 is an integer greater than or equal to 0, N3 is a positive integer, and the sum of N2 and N3 is equal to the preset threshold 1.

[0226] In some embodiments of the present application, N2 can also be referred to as M, and N3 can also be referred to as N.

[0227] In some implementations, the target CA combination is the first N3 CA combination different from the CA combination 1 in the CA combination set 5.

[0228] For example, continuing to refer to FIG. 11, the UE can determine the CA combination set 7 according to the union set of {CA1, CA2, CA4} and {CA1, CA2, CA4, CA8, CA3}.

[0229] For example, assuming that the number of CA combinations included in the public CA combination set 3 is N2, the CA combination set 7 can include N2 CA combinations 1 and N3 target CA combinations. Wherein, the N2 CA combinations 1 are included in the public CA combination set 3, and the N3 target CA combinations are included in the CA combination set 5. The N2 CA combinations 1 are different from the N3 target CA combinations. N2 is an integer greater than or equal to 0, N3 is a positive integer, and the sum of N2 and N3 is equal to the preset threshold 1.

[0230] S1010, the UE stores the CA combination set 7.

[0231] For example, after obtaining the CA combination set 7, the UE can first store the CA combination set 7. In order to facilitate the UE to obtain the CA combination set 7 from the memory when the UE uses the CA combination set 7 subsequently.

[0232] S1011, the UE sends the CA combination set 7 to the base station A when receiving the UE capability query message.

[0233] For example, the UE can send the CA combination set 7 to the base station A upon receiving the UE capability enquiry message. The UE sends the CA combination set 7 to the base station A in a similar manner as sending the CA combination set 6 to the base station A, and details are referred to the description of FIG. 9, which will not be repeated here. In some embodiments of the present application, the CA combination set 7 can also be referred to as the first CA capability information.

[0234] In the example of FIG. 10, both are described by taking at least one CA combination in the common CA combination set 3 as an example. In some embodiments of the present application, the common CA combination set 3 does not include the CA combination.

[0235] For example, the CA combination supported by the operator A is not included in the CA capability table 1. At this time, the UE determines that the CA combination is not included in the CA combination set 1 according to the CA capability table 1. In this example, the UE can determine that the common CA combination set 3 also does not include the CA combination by performing the process as in S1005.

[0236] For another example, the CA combination supported by the operator A is included in the CA capability table 1. That is, the CA combination set 1 includes at least one CA combination. In some implementations, there is no common CA combination between the CA combination set 1 supported by the operator A and the CA combination set 2 supported by the UE. In this implementation, the common CA combination set 3 also does not include the CA combination.

[0237] In this embodiment, according to the scheme shown in FIG. 10, the CA combination set 7 only includes the target CA combination in the CA combination set 5.

[0238] For example, still taking the preset threshold 1 equal to N1 as an example, the CA combination set 7 includes the first N1 target CA combinations in the CA combination set 5.

[0239] Compared with the scheme in FIG. 7, referring to FIG. 12, when the UE reports the UE capability information (such as the UE capability information 92) to the base station A, the UE can report N2 CA combinations supported by both the UE and the operator in addition to N3 target CA combinations supported by the UE and including the target frequency band supported by the operator A by performing the scheme in FIG. 10.

[0240] Therefore, the UE can report the CA combinations supported by the UE to the base station A more fully. Accordingly, the possibility of the base station A configuring the CA combination for the UE is further improved. Thus, the problem of communication lag in the UE can be avoided.
