Description

TECHNICAL FIELD

[0001] The present application relates to the field of mobile communication, in particular to a method and device for controlling radio frequency resources, a terminal and a computer readable storage medium. BACKGROUND

[0002] In order to increase the uplink and downlink throughput of a mobile terminal, carrier aggregation has been standardized in LTE-A by 3GPP as an important technology. Carrier aggregation technology is a development of traditional multicarrier technology, and its core idea is to divide a plurality of continuous or discrete frequency spectrums into a plurality of component carriers (CCs), allowing a terminal to simultaneously perform data transmission and reception on a plurality of sub-bands of the plurality of component carriers.

[0003] At present, in the carrier aggregation technology, when a terminal adds and activates a secondary cell according to a message issued by a network side, the terminal initiates multiple applications for radio frequency resources in the process of adding, measuring and activating, thereby causing multiple service interruptions to a primary cell and a secondary cell that are currently providing services, affecting the normal operation of terminal services and reducing the stability of data transmission. SUMMARY

[0004] Embodiments of the present application aim to provide a method and device for controlling radio frequency resources, a terminal and a computer readable storage medium, which can improve the stability of terminal services.

[0005] The technical solution of the present application is implemented as follows:

[0006] Embodiments of the present application provide a method for controlling radio frequency resources, comprising:

[0007] At a time of measuring a to-be-measured cell, a first radio frequency resource is applied for;

[0008] The to-be-measured cell is measured by using the first radio frequency resource;

[0009] In the case of receiving an activation instruction, an activation operation on the to-be-measured cell is performed.

[0010] Embodiments of the present application provide a device for controlling radio frequency resources, comprising:

[0011] A carrier aggregation module is configured to apply for a first radio frequency resource at a time of measuring a to-be-measured cell;

[0012] A measurement module is configured to measure the to-be-measured cell by using the first radio frequency resource;

[0013] The carrier aggregation module is further configured to perform an activation operation on the to-be-measured cell in the case of receiving an activation instruction.

[0014] The embodiment of the present application provides a terminal, comprising:

[0015] a memory, used for storing executable instructions;

[0016] a processor, used for executing the executable instructions stored in the memory, so as to realize the control method of the radio frequency resource provided by the embodiment of the present application.

[0017] The embodiment of the present application provides a computer readable storage medium, which stores executable instructions, and is used for causing the processor to execute the control method of the radio frequency resource provided by the embodiment of the present application.

[0018] The embodiment of the present application provides a chip, comprising a processor and a memory, wherein the memory is used for storing executable instructions; and the processor is used for running the executable instructions to execute the control method of the radio frequency resource provided by the embodiment of the present application.

[0019] The embodiment of the present application provides a computer program product, comprising a computer program or instructions, which are executed by the processor to realize the control method of the radio frequency resource provided by the embodiment of the present application.

[0020] The embodiment of the present application provides a control method, device, terminal and computer readable storage medium of radio frequency resource. When a first secondary cell to be added / deleted is parsed from a radio resource control reconfiguration message, the radio frequency resource of the terminal hardware is not applied to update the current secondary cell set of the terminal, so that the service being performed on the terminal is not interrupted. At the moment of measuring the to-be-measured cell, the first radio frequency resource is applied, so that the to-be-measured cell can be measured by using the allocated first radio frequency resource. In this way, by one-time radio frequency resource application and allocation, the current service cell of the service being performed only has one-time service interruption, that is, the cell measurement can be completed by using the applied first radio frequency resource, and the addition / deletion of the first secondary cell can be performed by using the first radio frequency resource. Compared with the multiple service interruptions caused by multiple radio frequency resource applications in the related art in the secondary cell addition / deletion and cell measurement stage, the number of service interruptions caused by radio frequency resource applications is reduced, so that the stability of the service on the terminal is improved.

[0030] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be described in further detail below with reference to the drawings, and the described embodiments should not be regarded as limiting the present application, and all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present application.

[0031] In the following description, "some embodiments" are described, which describe a subset of all possible embodiments, but it can be understood that "some embodiments" can be the same subset or different subset of all possible embodiments, and can be combined with each other without conflict.

[0032] In the following description, the terms "first\second\third" are only to distinguish similar objects, and do not represent a specific order of the objects, and it can be understood that "first\second\third" can be interchanged with a specific order or sequence as allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used herein are only for the purpose of describing the embodiments of the present application, and are not intended to limit the present application.

[0034] It should be understood that the technical solutions of the embodiments of the present application can be applied to the 4th generation mobile communication system (4G), a new radio (NR) system or a future communication system, and can also be used in other various wireless communication systems, for example: a narrowband Internet of Things (NB-IoT) system, a global system for mobile communication (GSM), an enhanced data rate for GSM evolution (EDGE) system, a wideband code division multiple access (WCDMA) system, a code division multiple access 2000 (CDMA2000) system, a time division-synchronous code division multiple access (TD-SCDMA) system, a general packet radio service (GPRS), a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD), a universal mobile telecommunications system (UMTS), etc.

[0035] Before the embodiments of the present application are further described in detail, the terms and phrases involved in the embodiments of the present application are explained, and the terms and phrases involved in the embodiments of the present application are applicable to the following explanations.

[0036] 1) Primary Cell (Pcell): In LTE-A system, after the User Equipment (UE) enters the connected state, it can use the carrier aggregation technology to communicate with the base station through multiple component carriers (such as CC1 and CC2), and the base station will specify a primary component carrier (PCC) for the UE through explicit configuration or according to the protocol agreement. Other component carriers are called secondary component carriers (SCC), and the serving cell on the PCC is called Pcell. The Pcell is the primary cell specified during connection establishment when the UE performs initial connection establishment, or performs RRC connection reestablishment, or in the handover process. The Pcell is determined. The PCell is responsible for RRC communication with the UE.

[0037] 2) Secondary Cell (SCell): Other cells participating in carrier aggregation. The serving cell on the SCC is called SCell. The SCell is added, modified and released by the RRC connection reconfiguration message RRCConnectionReconfiguration after the initial security activation procedure, and is used to provide additional radio resources. There is no RRC communication between the SCell and the UE.

[0038] 3) Serving Cell set: For the UE in the RRC connected state, the Serving Cell set can be composed of one PCell and at least one SCell when carrier aggregation is configured.

[0039] 4) Carrier Aggregation (CA): By aggregating multiple continuous or non-continuous component carriers, a larger transmission bandwidth is obtained, thereby obtaining higher peak rate and throughput.

[0040] Currently, 3GPP TS 38.133 and TS 38.321 have relatively detailed definitions and descriptions for the SCell addition and activation process. The basic process of SCell addition and activation includes: the network side issues an SCell addition message to the terminal through an RRC reconfiguration message, determines the newly added SCell as an inactive state after the terminal side completes the SCell addition, and performs cell measurement on the SCell in the inactive state through at least one measurement; until the network side issues an activation instruction for the newly added SCell through a medium access control-control element (MAC-CE), and notifies the terminal to start working on the newly activated SCell according to the activation instruction. That is, SCell addition and activation includes three stages of SCell addition, SCell measurement and SCell activation. In the above three stages, since the addition, measurement and activation of the secondary cell involve adjustment of the radio frequency resources in the terminal hardware resources, such as the need to reallocate the radio frequency hardware path. Since the radio frequency resources are public resources, the radio frequency resources are usually occupied by the current serving cell that is performing service processing in the normal running process of the terminal. Therefore, the adjustment of the radio frequency resources needs to interrupt the current serving cell that is using the radio frequency resources to reallocate the radio frequency resources on the current serving cell and the new secondary cell. It can be understood that interrupting the current running service will cause data packet loss and reduce the stability of the terminal service.

[0041] Currently, the protocol allows one interruption for each SCell addition and deletion stage, and one interruption for each SCell activation and deactivation process; for SCell measurement, the number of allowed interruptions is determined according to the measurement period and the bit error rate. Specifically, when the measurement period is greater than or equal to 640 milliseconds (ms), the bit error rate caused by service interruption due to measurement operation within the measurement period cannot exceed 0.5%. This means that under full throughput, when the measurement period is 640 ms, a maximum of 2 interruptions are allowed within each measurement period; when the measurement period is less than 640 ms, no interruption is allowed.

[0042] Taking the SCell addition and activation process with a measurement period of 640 ms as an example, when the SCell is added, according to the protocol description, due to the adjustment of the radio frequency resources, one interruption needs to be generated to other activated cells. Before the SCell is activated, each SCell measurement will cause one interruption due to the application of the radio frequency resources at the beginning of the measurement and the release of the radio frequency resources at the end of the measurement, that is, two interruptions. After receiving the activation instruction, the protocol still allows one more interruption, as shown in Figure 1 .

[0043] Therefore, based on the related art of the protocol, when adding and activating a secondary cell for a terminal, multiple service interruptions to the already activated cell are caused, affecting the data service of the terminal. If only the minimum interruption times are considered and the RF resource application is completed at the time of SCell addition (only one interruption is caused), and no further adjustment is made to the RF resource, in the stage before the activation of the SCell, the RF opening causes excessive power consumption, leading to the increase of the power consumption of the terminal.

[0044] The embodiment of the present application provides a kind of control method, device and computer readable storage medium of radio frequency resource, can improve the stability of service on terminal, the exemplary application of terminal provided by the embodiment of the present application is explained below, the terminal provided by the embodiment of the present application can be implemented as notebook computer, tablet computer, desktop computer, set top box, mobile device (for example, mobile phone, portable music player, personal digital assistant, dedicated message device, portable game device) and various types of user terminals.

[0045] Reference is made to Figure 2 , Figure 2 It is an optional flowchart of the control method of radio frequency resource provided by the embodiment of the present application, which will be described in combination with the steps shown in Figure 2 .

[0046] S101, at the moment of measuring the cell to be measured, apply the first radio frequency resource.

[0047] The embodiment of the present application is applicable to the scenario of adding, activating, deactivating or deleting secondary cell on the terminal configured with carrier aggregation of service cell set. The terminal in the embodiment of the present application supports CA capability, and has registered and accessed to the primary cell through RRC connection establishment process.

[0048] The terminal involved in the embodiment of the present application can include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other electronic devices connected to wireless modems, and various forms of user terminals (terminal devices) or mobile stations (Mobile Station, MS) and the like.

[0049] In some embodiments, the terminal can report its CA capability in the Attach message sent to the network device through the registration process, so that the network side configures Pcell and Scell cell for the terminal according to the CA capability reported by the terminal, and increases the frequency band resource of the terminal.

[0050] Exemplarily, a base station (evolved NodeB, eNodeB) can inquire the capability of a UE by sending an RRC message of UECapabilityEnquiry, and the UE can inform the eNodeB of its wireless access capability by replying a UECapabilityInformation message. The UECapabilityInformation contains ca-BandwidthClassUL-r10 and ca-BandwidthClassDL-r10 information, which indicates the maximum number of carriers supported by the UE and the number of aggregable Resource Blocks (RBs), etc. Taking ca-BandwidthClassDL-r10 as an example, if the ca-BandwidthClassDL-r10 is a preset A category, it indicates that the UE supports only one carrier in downlink; if the ca-BandwidthClassDL-r10 is a preset category, it indicates that the UE supports two carriers in downlink.

[0051] In the embodiments of the present application, the network device will further add or delete a secondary cell SCell for the terminal based on a measurement report MeasurementReport according to the coverage condition in the case that the terminal has CA capability. Here, the SCell addition and deletion are mainly initiated by the network device through issuing an RRC reconfiguration message (RRCConnectionReconfiguration) at the RRC layer.

[0052] In the embodiments of the present application, the terminal parses the RRC reconfiguration message when receiving the RRC reconfiguration message issued by the network device, and determines the first secondary cell to be updated carried in the RRC reconfiguration message. Here, the first secondary cell to be updated includes at least one of the first secondary cell to be added and the first secondary cell to be deleted.

[0053] In S101, the terminal needs to adjust the configuration of the radio frequency resource so that the radio frequency resource can cover the first secondary cell to be updated, so as to complete the addition or deletion of the first secondary cell according to the indication of the network side. However, since the radio frequency resource on the terminal is being occupied by the current serving cell of the terminal for business processing such as data transmission and reception, the terminal needs to apply for the radio frequency resource and interrupt the business of the current serving cell, so as to adjust the configuration of the radio frequency resource.

[0054] In the embodiments of the present application, since there is no data service demand in the stage of adding or deleting the secondary cell, the radio frequency resource does not need to be applied immediately, and the terminal can not initiate the application of the radio frequency resource in the case that the first secondary cell to be added / deleted is determined, so as to avoid interrupting the data service currently being processed by the terminal.

[0055] In some embodiments, the terminal can first record the first secondary cell to be added / deleted, and wait for a measurement event to be triggered, and then initiate the application of the radio frequency resource.

[0056] In some embodiments, before S101, the terminal can further perform S001, as follows:

[0057] S001, in the case where a measurement event is triggered, determining a time for measuring a cell to be measured based on a measurement period.

[0058] In S001, the terminal can perform measurement point planning according to the measurement period issued by the network side, and determine a time point for starting to perform the measurement operation, i.e., a time for measuring the cell to be measured.

[0059] For example, the terminal can perform measurement point planning according to the measurement period through a measurement module, and determine a time for measuring the cell to be measured.

[0060] In the embodiments of the present application, the terminal applies the first radio frequency resource for the cell to be measured corresponding to the measurement event at the time of starting the measurement operation.

[0061] In the embodiments of the present application, the measurement event can be a measurement instruction issued by the network device, such as a neighbor cell measurement trigger configured by the network device, or a cell search trigger initiated by the terminal at a regular time. In the case where a measurement event is triggered, the terminal applies a radio frequency resource at the time of starting the measurement operation, so as to use the radio frequency resource to perform cell measurement on the cell to be measured corresponding to the measurement event.

[0062] In some embodiments, in the case where a measurement event is triggered, the terminal determines a cell to be measured according to the measurement event. Here, in the case where the first secondary cell to be added is determined, the cell to be measured at least includes the first secondary cell to be added / deleted.

[0063] For example, in the case where the first secondary cell to be added is determined, the terminal can determine the first secondary cell to be measured, or can determine the first secondary cell, the current serving cell, and the same-frequency neighbor cell of the first secondary cell as the cell to be measured, which is selected according to actual conditions, and the embodiments of the present application are not limited in this regard.

[0064] In some embodiments, the terminal can further perform S201-S202, as shown in Figure 3 as follows:

[0065] S201, determining the first secondary cell to be added / deleted.

[0066] In the embodiments of the present application, the first secondary cell to be added / deleted is the secondary cell to be added / deleted determined by the terminal by receiving and analyzing the radio resource control reconfiguration message issued by the network side.

[0067] In some embodiments, the terminal can parse the network signaling or message issued by the network side through the configuration management module. When the first secondary cell to be added is parsed in the radio resource control layer reconfiguration message, the configuration management module notifies the carrier aggregation module of the first secondary cell. Here, the carrier aggregation module is used to manage the carrier aggregation services such as secondary cell addition, deletion and activation by interacting with the public function module on the terminal. The public function module can be a common module that provides service functions for common services in multiple service modules on the terminal. For example, the public function module can include a configuration management module, a radio frequency management module, a measurement module, and the like.

[0068] In some embodiments, the configuration management module described above can update the first secondary cell to be added parsed to the configuration database maintained by itself to record and manage the secondary cells and their states in the current secondary cell set on the terminal. In the case where the carrier aggregation module receives the first secondary cell to be added notified by the configuration management module, the first secondary cell is determined to be in the state of to be added.

[0069] S202, adding / deleting the first secondary cell by using the first radio frequency resource.

[0070] In S202, in the case of allocating the first radio frequency resource, the terminal adds or deletes the first secondary cell by using the radio frequency resource corresponding to the frequency point range of the first secondary cell in the first radio frequency resource, to update the current secondary cell set of the terminal.

[0071] In some embodiments, the carrier aggregation module adds the first secondary cell to be added by using the first radio frequency resource, and determines the first secondary cell to be in the state of added.

[0072] It should be noted that the present application does not limit the execution order of the terminal adding / deleting the first secondary cell by using the first radio frequency resource, and starting the measurement by using the first radio frequency resource. In some embodiments, different modules can be used to perform the processes in parallel, and the specific selection is based on the actual situation.

[0073] For example, after updating the first secondary cell by using the first radio frequency resource, the terminal can start the measurement of the to-be-measured cell corresponding to the first secondary cell by using the same function module on the terminal. Alternatively, different function modules can be used to synchronously process the processes of secondary cell update and cell measurement by using the first radio frequency resource, for example, the carrier aggregation module is used to add / delete the secondary cell, and the measurement module is used to measure the cell, and the like. The specific selection is based on the actual situation, and the present application does not limit the selection.

[0074] In some embodiments, the first secondary cell can include a plurality of secondary cells, and the terminal can determine a plurality of secondary cells to be added / deleted currently, and perform adding / deleting operation on the plurality of secondary cells to be added / deleted using the first radio frequency resource. For example, before the terminal applies for the first radio frequency resource, the terminal has recorded a plurality of secondary cells to be added / deleted; or after the terminal initiates the application for the first radio frequency resource for a certain secondary cell to be added / deleted issued by the network side, the network side issues a new secondary cell to be added / deleted before the allocation of the first radio frequency resource is completed, and the terminal can perform adding / deleting operation on the plurality of secondary cells to be added / deleted currently using the first radio frequency resource currently applied for.

[0075] It can be understood that the terminal can perform adding / deleting operation on the plurality of secondary cells to be added / deleted currently using the first radio frequency resource obtained through one radio frequency resource application, which reduces the service interruption caused by multiple radio frequency applications for adding / deleting each secondary cell in the plurality of secondary cells to be added / deleted, and improves the stability of services on the terminal.

[0076] In some embodiments, the terminal interrupts the data service on the current serving cell when the radio frequency resource is allocated.

[0077] Here, the current serving cell can include a primary cell to which the terminal is currently registered, or can include the primary cell and at least one activated secondary cell. The terminal initiates the radio frequency resource application for the to-be-measured cell, and interrupts the data service on the current serving cell when the radio frequency resource is allocated.

[0078] In some embodiments, the interruption time length of the data service on the current serving cell can be determined according to the frequency band relationship between the first secondary cell to be updated and the current serving cell. The terminal can determine whether the first secondary cell to be updated and the current serving cell are in adjacent relationship according to the frequency band numbers of the first secondary cell to be updated and the current serving cell, and then determine the first interruption time length corresponding to the adjacent relationship or the second interruption time length corresponding to the non-adjacent relationship.

[0079] In the embodiments of the present application, the terminal adjusts the configuration of the current radio frequency resource based on the to-be-measured cell within the interruption time length of the current serving cell, and determines the first radio frequency resource.

[0080] For example, the terminal can adjust the radio frequency resource based on the frequency band range of the to-be-measured cell to determine the first radio frequency resource. It can be understood that the first radio frequency resource includes the radio frequency resource allocated for the frequency band of the first secondary cell in the to-be-measured cell, and the radio frequency resource allocated for the frequency band of other cells in the to-be-measured cell.

[0081] S102, measuring the to-be-measured cell by using the first radio frequency resource.

[0082] In the embodiments of the present application, the terminal starts the measurement operation by using the allocated first radio frequency resource, and measures the to-be-measured cell.

[0083] In some embodiments, according to the measurement period, the terminal can also determine the measurement end time. Thus, for a measurement period, the terminal applies for the first radio frequency resource for the to-be-measured cell when measuring the to-be-measured cell, that is, when the measurement start time determined according to the measurement period is reached; measures the to-be-measured cell by using the first radio frequency resource, and adds / deletes the first secondary cell by using the first radio frequency resource; and stops the measurement operation on the to-be-measured cell when the measurement end time is reached.

[0084] S103, performing the activation operation on the to-be-measured cell in the case of receiving the activation instruction.

[0085] In the embodiments of the present application, the terminal determines that the first secondary cell is in the added state, that is, the deactivated state, when the addition of the first secondary cell is completed. The secondary cell in the deactivated state does not participate in the data transmission of the terminal, and the terminal only performs the necessary cell measurement on it and reports it to the network device. The terminal measures the to-be-measured cell by using the first radio frequency resource, and reports the measurement result to the network device. In this way, the network device can issue an activation instruction for the added first secondary cell in the to-be-measured cell according to the measurement result reported by the terminal, to activate the first secondary cell, use the radio frequency resource of the first secondary cell to run the terminal service, and improve the available bandwidth and data throughput on the terminal.

[0086] For example, when the wireless channel quality of a certain secondary cell is good and the traffic amount of the UE is large, the eNodeB will carry the activation instruction in the MAC-CE message and issue it to the terminal, so that the secondary cell is in the activated state, and the data transmission rate is improved. Here, MAC-CE is a way of exchanging control information between the UE and the network in addition to RRC messages and NAS messages, and is used to exchange MAC layer control information.

[0087] In some embodiments, the terminal stops the ongoing measurement and activates the first secondary cell in the case of receiving the activation instruction for the first secondary cell and measuring the to-be-measured cell. Here, the first secondary cell is included in the to-be-measured cell.

[0088] In some embodiments, the terminal activates the first secondary cell upon receiving the activation instruction for the first secondary cell without performing measurement. For example, the terminal receives the activation instruction for the first secondary cell after the end of a measurement period and before the start of the next measurement period, and the terminal does not perform measurement at this time, and directly activates the first secondary cell.

[0089] It can be understood that, in the embodiments of the present application, when the first secondary cell to be added / deleted is parsed from the radio resource control reconfiguration message, the terminal hardware radio frequency resource is not applied for updating the current secondary cell set of the terminal, so that the ongoing service of the terminal is not interrupted. At the time of measuring the to-be-measured cell, the first radio frequency resource is applied for, so that the to-be-measured cell can be measured by using the allocated first radio frequency resource. In this way, by one-time radio frequency resource application and allocation, the current service cell of the ongoing service is only interrupted once, that is, the cell measurement can be completed by using the applied first radio frequency resource, and the addition / deletion of the first secondary cell can be performed by using the first radio frequency resource. Compared with the multiple service interruptions caused by multiple radio frequency resource applications in the related art during the addition / deletion of the secondary cell and the cell measurement stage, the embodiments of the present application reduce the number of service interruptions caused by radio frequency resource applications, thereby improving the stability of the service of the terminal.

[0090] In some embodiments, based on Figure 2 , after the measurement of the to-be-measured cell by using the first radio frequency resource in S102, S301 or S302 can be performed as shown in Figure 4 .

[0091] S301, in the case that the measurement period is less than the preset threshold and the measurement is completed, the first radio frequency resource is not released.

[0092] In the embodiments of the present application, in the case that the measurement of the to-be-measured cell by using the first radio frequency resource is completed, whether to release the first radio frequency resource can be determined according to the measurement period.

[0093] Here, since the protocol specifies a preset bit error rate threshold caused by service interruption due to measurement within the measurement period, for example, the protocol specifies that the bit error rate caused by service interruption due to measurement within the measurement period cannot exceed 0.5% when the measurement period is greater than 640 ms. Therefore, the preset threshold corresponding to the measurement period can be determined according to the preset bit error rate threshold, so that the bit error rate of service interruption within the measurement period is lower than the preset bit error rate threshold by using the preset threshold. That is, the preset threshold corresponds to the bit error rate.

[0094] For S301, if the measurement period is less than the preset threshold and the measurement is completed, it indicates that the service interruption caused by releasing the radio frequency resource at this time can cause the bit error rate to be higher than the preset bit error rate threshold. After the terminal completes the measurement on the to-be-measured cell, the radio frequency resource is not released, so as to ensure the stability of the service running on the terminal.

[0095] Exemplarily, the preset bit error rate threshold can be 0.5%, and the preset threshold can be 640 ms. When the measurement period is less than 640 ms, if the first radio frequency resource is released after the measurement is completed, the service interruption will be caused to the current serving cell, so that the bit error rate is higher than the protocol requirement of 0.5%. Therefore, when the measurement period is less than 640 ms, the terminal does not release the first radio frequency resource after the measurement on the to-be-measured cell is completed.

[0096] It should be noted that in the embodiments of the present application, the preset threshold can be flexibly set based on the protocol provision and the actual service requirement, and the specific selection is made according to the actual situation, which is not limited in the embodiments of the present application.

[0097] S302, in the case that the measurement period is greater than or equal to the preset threshold and the measurement is completed, the first radio frequency resource is released.

[0098] In S302, in the case that the measurement period is greater than or equal to the preset threshold, the terminal releases the first radio frequency resource when the measurement on the to-be-measured cell is completed, so as to avoid unnecessary power consumption waste caused by long-time opening or occupation of the radio frequency resource, thereby reducing the power consumption on the terminal and improving the endurance of the terminal.

[0099] It can be understood that in the embodiments of the present application, whether to release the radio frequency resource for measurement application is determined based on the measurement period. In the case that the measurement period is less than the preset threshold, the radio frequency resource is not released to reduce the service interruption times and the bit error rate, and the radio frequency resource that is not released can be used for the next measurement or activation, so as to further reduce the service interruption times and improve the service stability. In the case that the measurement period is greater than or equal to the preset threshold, the radio frequency resource can be released in time to reduce the power consumption and improve the endurance of the terminal. Therefore, on the premise of meeting the basic requirements of the protocol, the balance between the minimum influence on the services of other activated cells and the radio frequency power consumption is achieved.

[0100] In some embodiments, upon receiving an activation command, the terminal can determine whether available radio frequency (RF) resources exist, i.e., RF resources corresponding to the measurement. Here, the RF resources corresponding to the measurement can be RF resources for ongoing measurements that have not yet been released, or RF resources for measurements that have been completed but whose measurement period is less than a preset threshold and have not yet been released. If RF resources corresponding to the measurement exist, the terminal uses these RF resources to activate the first secondary cell. In this way, secondary cell activation can be achieved without re-applying for RF resources in response to the activation command, reducing the number of service interruptions.

[0101] In some embodiments, based on Figure 2 or Figure 4 ,like Figure 5 As shown, S103 can be implemented by any of the processes S1031-S1034, as follows:

[0102] S1031. Upon receiving the activation command for the first secondary cell and while measuring the cell to be measured, the measurement is stopped, and the first secondary cell is activated using the radio frequency resources corresponding to the measurement.

[0103] In this embodiment, the radio frequency resources corresponding to the measurement may include: a first radio frequency resource. For S1031, when the terminal is performing a measurement using the first radio frequency resource, upon receiving an activation command, the first radio frequency resource can be used to activate the first secondary cell specified in the activation command, thereby reducing service interruptions caused by radio frequency resource requests.

[0104] In this embodiment, the radio frequency resources corresponding to the measurement may further include: radio frequency resources corresponding to the current measurement period. Since multiple measurements may be performed for various measurement periods before the terminal receives the activation command, for the current measurement period, the terminal requests the radio frequency resources corresponding to the current measurement period at the moment when measuring the cell to be measured within the current measurement period. For S1031, if the terminal uses the radio frequency resources corresponding to the current measurement period to measure the cell to be measured and receives the activation command for the first secondary cell, it can activate the first secondary cell using the radio frequency resources corresponding to the current measurement period.

[0105] S1032. Upon receiving the activation command for the first secondary cell and performing a measurement on the cell to be measured, the first secondary cell is activated using the radio frequency resources corresponding to the measurement after the measurement is completed.

[0106] In S1032, if the terminal receives an activation command for the first secondary cell while measuring the cell to be measured, it will activate the first secondary cell using the radio frequency resources corresponding to the measurement after the measurement is completed.

[0107] In some embodiments, when the measurement period is greater than or equal to the preset threshold, if the terminal receives the activation instruction while performing measurement on the to-be-measured cell, the terminal activates the first secondary cell using the radio frequency resource corresponding to the measurement after the measurement is completed, and releases the radio frequency resource corresponding to the measurement after the activation of the secondary cell is completed. For example, when the measurement period is greater than or equal to 640 ms, if the terminal receives the activation instruction of the first secondary cell while performing measurement on the to-be-measured cell, the terminal can first record the first secondary cell to be activated in the activation instruction; after the measurement is completed, it is determined whether there is a first secondary cell to be activated; in the case where there is a first secondary cell to be activated, the first secondary cell is activated using the radio frequency resource corresponding to the measurement, and then the first radio frequency resource is released. In the case where there is no first secondary cell to be activated, the first radio frequency resource is directly released to reduce power consumption.

[0108] It should be noted that when the measurement period is less than the preset threshold, the terminal can first complete the measurement and then activate the first secondary cell using the radio frequency resource corresponding to the measurement after receiving the activation instruction of the first secondary cell and performing measurement on the to-be-measured cell.

[0109] S1033, in the case where the activation instruction of the first secondary cell is received and no measurement is performed, a second radio frequency resource is applied, and the activation of the first secondary cell is realized using the second radio frequency resource.

[0110] In S1033, in the case where the activation instruction of the first secondary cell is received and no measurement is performed, it is indicated that the radio frequency resource corresponding to the measurement may have been released, and there is no available radio frequency resource. The terminal reinitiates the application of the radio frequency resource, allocates a second radio frequency resource for the first secondary cell to be activated, and realizes the activation of the first secondary cell using the second radio frequency resource.

[0111] In some embodiments, when the terminal receives the activation instruction of the added first secondary cell issued by the network device, if the measurement on the to-be-measured cell has ended and the radio frequency resource corresponding to the measurement has been released, it is indicated that there is currently no prepared radio frequency resource. The terminal applies for the radio frequency resource, and realizes the activation of the first secondary cell using the allocated second radio frequency resource.

[0112] S1034, in the case where the activation instruction of the first secondary cell is received and no measurement is performed, the activation of the first secondary cell is realized using the radio frequency resource corresponding to the measurement.

[0113] In S1034, when the terminal receives the activation instruction of the first secondary cell and no measurement is performed, the terminal can further determine whether there is a measurement corresponding radio resource. Here, the measurement corresponding radio resource can be a measurement radio resource which is not released and which corresponds to a measurement period less than a preset threshold. When there is a measurement corresponding radio resource, the terminal can not reapply for a radio resource, and use the measurement corresponding radio resource to realize the activation of the first secondary cell.

[0114] In some embodiments, when the measurement period is less than the preset threshold and the measurement using the first radio resource is completed, the terminal does not release the first radio resource; and when the terminal receives the activation instruction of the first secondary cell, the terminal uses the first radio resource to realize the activation of the first secondary cell.

[0115] For example, after the terminal completes the measurement of a measurement period less than 640 ms, the terminal does not release the first radio resource. In this way, when the terminal receives the activation instruction of the first secondary cell, even if there is no ongoing measurement, the terminal can determine that there is a first radio resource which is not released, and use the first radio resource to realize the activation of the first secondary cell.

[0116] It should be noted that, when the secondary cell is in the activated state, the terminal consumes more power. When the wireless channel quality of the secondary cell is poor or the UE traffic is small, the network device can trigger a certain secondary cell of the UE to be in the deactivated state based on the MAC CE message issued by the network device or the timeout event of the activation timer of the terminal, so as to reduce the consumption of wireless resources and the power consumption of the UE. For the deactivation event triggered on the activated first secondary cell, the terminal can use the measurement corresponding radio resource to realize the deactivation of the first secondary cell when there is a measurement corresponding radio resource; otherwise, the terminal re-applies for a radio resource to deactivate the first secondary cell. Here, the deactivation process is similar to the above-mentioned activation process, and will not be described herein again.

[0117] It can be understood that, by using the measurement corresponding radio resource to activate the first secondary cell, the application embodiment reduces the service interruption caused by the application for a radio resource in the activation stage, thereby fully utilizing the available radio resource, reducing unnecessary service interruption, and improving the service stability.

[0118] Based on the above-mentioned embodiments, for the addition and activation of the secondary cell in the carrier aggregation scenario, the execution strategy of the radio resource control method provided by the application embodiment in each stage can be as shown in Table 1, as follows:

[0119] Table 1

[0120]

[0121] It can be understood that in the embodiments of the present application, when the terminal receives the activation instruction of the added first secondary cell, based on the measurement situation of the to-be-measured cell, in the case that the measurement situation represents that there is unreleased radio frequency resource, for example, there is unreleased radio frequency resource after the measurement with a measurement period less than 640 ms is completed, or there is unreleased radio frequency resource in the ongoing measurement, the terminal can directly use the unreleased radio frequency resource for secondary cell activation. In this way, compared with the related art, the service interruption caused by the application of radio frequency resources in the overall addition, measurement and activation operation process of the secondary cell is reduced, thereby improving the stability of the service on the terminal.

[0122] In some embodiments, for the scenario of adding or activating multiple secondary cells by the terminal, if radio frequency resource is applied for each of the multiple secondary cells to add or activate it, the number of service interruptions to the current serving cell will be multiplied, which seriously affects the stability of the service on the terminal. The embodiments of the present application provide a control method of radio frequency resources, which can reduce the number of service interruptions by fusing the measurement time points or activation time points of different secondary cells in the scenario of simultaneously adding or activating multiple secondary cells. As follows:

[0123] In some embodiments, the radio resource control reconfiguration message issued by the network device carries the multiple secondary cells to be added and the measurement periods of the multiple secondary cells, and the terminal can perform S401-S404 as shown in Figure 6 As follows:

[0124] S401, determining the second measurement start time and the second measurement end time of each secondary cell according to the measurement period of each secondary cell to be added.

[0125] In S401, the terminal determines the second measurement start time and the second measurement end time corresponding to each secondary cell according to the measurement period of each secondary cell.

[0126] S402, determining the first measurement start time between target secondary cells in the multiple secondary cells, based on the multiple second measurement start times and the multiple second measurement end times, the time difference between which is less than a preset time difference threshold.

[0127] In S402, the terminal fuses and analyzes the multiple second measurement start times and the multiple second measurement end times corresponding to the multiple secondary cells, determines the target secondary cells with a time difference less than a preset time difference threshold between the multiple second measurement start times and the multiple second measurement end times, and determines the first measurement start time and the first measurement end time according to the second measurement start time and the second measurement end time of the target secondary cells.

[0128] Exemplarily, the time difference between the second measurement end time of the secondary cell 1 and the second measurement start time of the secondary cell 2 is less than the preset time difference threshold, which indicates that the measurement on the secondary cell 1 will be ended and the measurement on the secondary cell 2 will be started soon. The terminal takes the secondary cell 1 and the secondary cell 2 as target secondary cells; and the terminal determines a first measurement start time and a first measurement end time according to the second measurement start time and the second measurement end time of the secondary cell 1 and the secondary cell 2 respectively, and uses the first measurement start time and the first measurement end time to measure the secondary cell 1 and the secondary cell 2. Exemplarily, the earliest second measurement start time in the target secondary cells is taken as the first measurement start time, and the latest second measurement end time is taken as the first measurement end time.

[0129] S403, according to the first measurement start time, a first radio frequency resource is allocated to a to-be-measured cell determined based on the target secondary cell.

[0130] In S403, the target secondary cell includes multiple secondary cells with a measurement period less than the preset time difference threshold, and the terminal determines a to-be-measured cell based on the multiple secondary cells, and allocates a first radio frequency resource to the to-be-measured cell in a first time slot before the first measurement start time.

[0131] S404, in the case of reaching the first measurement start time, a measurement operation on the to-be-measured cell is started by using the first radio frequency resource.

[0132] In S404, in the case of reaching the first measurement start time, the terminal can start the measurement operation on the to-be-measured cell by using the first radio frequency resource. Exemplarily, the measurement on each cell in the to-be-measured cell is started in the order of the second measurement start time of each cell in the to-be-measured cell, and in the case of not reaching the first measurement start time, the first radio frequency resource is not released and the first radio frequency resource is continuously used to measure the cells in the to-be-measured cell which have not been measured.

[0133] Exemplarily, in the target secondary cells, the second measurement start time of the secondary cell 1 is earlier than the second measurement start time of the secondary cell 2, and the time difference between the second measurement end time of the secondary cell 1 and the second measurement start time of the secondary cell 2 is less than the preset time threshold, then the terminal can perform a radio frequency resource application according to the radio frequency application time determined by the first measurement start time, perform radio frequency resource allocation on the to-be-measured cell determined based on the secondary cell 1 and the secondary cell 2, and obtain a first radio frequency resource. In the case of reaching the first measurement start time, the terminal starts the measurement on the secondary cell 1 by using the first radio frequency resource, and after the measurement on the secondary cell 1 is ended, the measurement on the secondary cell 2 is started by using the first radio frequency resource. Of course, the measurement can also be performed in parallel according to the second measurement start time of the secondary cell, and the specific selection is made according to the actual situation, which is not limited in the embodiments of the present application.

[0134] S405, in the case of reaching the first measurement end time, stopping the measurement operation on the to-be-measured cell.

[0135] In S405, before reaching the first measurement end time, during the measurement process on the target to-be-measured cell, the terminal can use the first radio frequency resource to measure the current cell in the to-be-measured cell. When the measurement on the current cell reaches the end of the measurement period, and the next cell in the to-be-measured cell reaches the beginning of the measurement period, the first radio frequency resource is not released, and the measurement update of the next cell is completed; and the next cell is measured using the first radio frequency resource until the measurement on the to-be-measured cell is completed.

[0136] It can be seen that by merging the second measurement start time and the second measurement end time of multiple secondary cells to obtain the first measurement start time and the first measurement end time, and based on the to-be-measured cell determined by the target secondary cell, the radio frequency resource application can be completed through one radio frequency resource application. The radio frequency resource adjustment for operating at least two secondary cells in the target secondary cell.

[0137] In some embodiments, for the case of simultaneously adding or activating multiple secondary cells, taking the simultaneous activation of multiple secondary cells as an example, the terminal can activate the current secondary cell in the multiple secondary cells according to the activation instruction of the current secondary cell in the multiple secondary cells added. When the current activation time is adjacent to the next activation time of the next secondary cell, the radio frequency resource for activating the current secondary cell is used to activate the next secondary cell until the activation of the multiple secondary cells is completed. Here, the current activation time being adjacent to the next activation time can include that the time difference between the current activation time and the next activation time is less than a preset time difference threshold. In this way, through one radio frequency resource application, only one service interruption is caused, and the activation of the multiple secondary cells can be completed, thereby reducing the number of service interruptions and improving the stability of the service on the terminal.

[0138] In some embodiments, the terminal can also determine the activation time of the multiple secondary cells according to the activation instruction of the multiple secondary cells added; determine a target activation time based on the activation time of the multiple secondary cells; and achieve the synchronous activation of the multiple secondary cells at the target activation time.

[0139] For example, the terminal can determine the maximum value, the minimum value, or the average value of the activation time of the multiple secondary cells as the target activation time. In this way, based on one target activation time, the radio frequency resource application and the service interruption are implemented once, and the synchronous activation of the multiple secondary cells is achieved.

[0140] It can be understood that, in the embodiments of the present application, by fusing the adding and activating processes of the plurality of secondary cells, the time point of service interruption due to radio frequency adjustment is maximally reused, the number of service interruptions is further reduced, and the stability of services on the terminal is improved.

[0141] In the following, an exemplary application of the embodiments of the present application in an actual application scenario will be described. The control method of radio frequency resources provided by the embodiments of the present application can be implemented by combining the existing public function modules on the terminal. As shown in Figure 7 The function modules on the terminal include a configuration management module 100, a carrier aggregation module 200, a radio frequency management module 300, a measurement module 400, and an interruption management module 500. Among them, the configuration management module 100, the radio frequency management module 300, the measurement module 400, and the interruption management module 500 can be public function modules on the terminal, wherein the configuration management module 100 is configured to store, issue, and configure the underlying hardware according to the RRC configuration issued by the network device. The radio frequency management module 300 is configured to manage the radio frequency hardware resources on the terminal. The measurement module 400 is configured to manage the measurement operation on the terminal. The interruption management module 500 is configured to initiate service interruption on the current serving cell. In some embodiments, the above-mentioned configuration management module 100, carrier aggregation module 200, radio frequency management module 300, measurement module 400, and interruption management module 500 can be configured in the baseband chip of the terminal.

[0142] Based on the public function modules of the terminal, the embodiments of the present application introduce the carrier aggregation module 200 for managing the carrier aggregation secondary cell, and through the interaction between the modules, the radio frequency resources are controlled in the adding / deleting, measurement, and activating processes of the secondary cell, so as to improve the terminal service stability and reduce the power consumption.

[0143] As shown in Figure 7 As shown in

[0144] S801, when the configuration management module 100 parses that the radio resource control layer reconfiguration message contains a first secondary cell to be added, the configuration management module 100 notifies the carrier aggregation module 200 of the first secondary cell to be added.

[0145] In the embodiments of the present application, the configuration management module 100 receives and parses the radio resource control layer reconfiguration message, and when it is parsed that the first secondary cell to be added is contained, the configuration management module 100 notifies the carrier aggregation module 200 of the first secondary cell to be added, so as to notify the carrier aggregation module 200 to manage the first secondary cell to be added.

[0146] S802, the carrier aggregation module 200 determines the first secondary cell as a state to be added.

[0147] In the embodiment, the carrier aggregation module 200 determines the first secondary cell as the state to be added when receiving the first secondary cell to be added informed by the carrier aggregation module.

[0148] S803, the configuration management module 100 updates the first secondary cell to the configuration database of the terminal.

[0149] In the embodiment, the configuration database of the terminal can be used to maintain the configuration information of the corresponding primary cell and the secondary cell in each state of the terminal. When the configuration management module 100 parses that the radio resource control layer reconfiguration message contains the first secondary cell to be added, the configuration management module 100 updates the first secondary cell to be added to the configuration database of the terminal.

[0150] It should be noted that when the configuration management module 100 parses that the radio resource control layer reconfiguration message contains the first secondary cell to be added, the configuration management module 100 informs the carrier aggregation module 200 of the first secondary cell to be added, and the execution order of S802 and S803 is not limited in the embodiment.

[0151] S804, the measurement module 400 determines the measurement start time, that is, the time of measuring the to-be-measured cell, and the measurement end time according to the measurement period in the radio resource control reconfiguration message.

[0152] In the embodiment, the measurement module 400 can determine the measurement start time and the measurement end time of measuring the first secondary cell to be added according to the measurement period carried in the radio resource control reconfiguration message in S801 through receiving the measurement instruction of the network device or triggering the timeout event of the timing measurement by itself.

[0153] S805, if the measurement period is less than 640ms, the measurement module 400 initiates a radio frequency resource application for the to-be-measured cell determined based on the first secondary cell to the radio frequency chip at the measurement start time, and the radio frequency chip allocates the first radio frequency resource based on the radio frequency resource application. The measurement module 400 measures the to-be-measured cell by using the allocated first radio frequency resource.

[0154] In the embodiment, if the measurement period is less than 640ms, the measurement module 400 determines the to-be-measured cell based on the first secondary cell, initiates a radio frequency resource application at the time of measuring the to-be-measured cell, and the radio frequency chip allocates the first radio frequency resource. The measurement module 400 measures the to-be-measured cell by using the first radio frequency resource.

[0155] In the embodiment, since the measurement period is less than 640ms, the measurement module 400 does not release the first radio frequency resource after measuring the to-be-measured cell by using the first radio frequency resource.

[0156] S806, if the measurement period is greater than or equal to 640 ms, the measurement module 400 informs the carrier aggregation module 200 of the measurement start time and the measurement end time determined according to the measurement period.

[0157] S807, the carrier aggregation module 200 determines the radio resource application time according to the measurement start time and the measurement end time fed back by the measurement module 400, and informs the radio management module 300 of the radio resource application time.

[0158] Here, the radio resource application time planned and determined by the carrier aggregation module 200 is the measurement start time, that is, the time when the cell to be measured is measured.

[0159] S808, the radio management module 300 applies for radio resources from the radio chip according to the radio resource application time, determines the radio resources allocated by the radio chip for the cell to be measured as the first radio resources, and adjusts the current radio resource configuration of the terminal according to the first radio resources.

[0160] S809, the radio management module 300 informs the interrupt management module 500 to initiate an interrupt to the current serving cell to interrupt the data service on the current serving cell.

[0161] S810, the radio management module 300 feeds back to the carrier aggregation module 200 that the application of the first radio resources is successful.

[0162] Here, S810 is executed after S808. S808 can be performed synchronously with S809, or can be executed in any order, and the application embodiments are not limited.

[0163] S811, after the configuration management module 100 updates the first secondary cell to the configuration database of the terminal, the carrier aggregation module 200 is informed that the configuration database update of the first secondary cell is completed.

[0164] It should be noted that the process of S811 can be executed in the process after S803 and before S810. For example, S811 can be executed after S803 to feed back to the carrier aggregation module 200 that the addition of the first secondary cell is completed. The specific selection is made according to the actual situation, and the application embodiments are not limited.

[0165] S812, the carrier aggregation module 200 completes the addition of the first secondary cell by using the first radio resources in the case that the application of the first radio resources is successful and the configuration database update of the first secondary cell is completed, and determines the first secondary cell as an added state, that is, a non-active state.

[0166] S813, the configuration management module 100 notifies the carrier aggregation module 200 of the receipt of the activation instruction for the first secondary cell when it is parsed that the MAC-CE message issued by the network device carries the activation instruction for the first secondary cell.

[0167] S814, the carrier aggregation module 200 updates the state of the first secondary cell to the to-be-activated state.

[0168] S815, the carrier aggregation module 200 determines a second radio resource application time for initiating the application of the second radio resource in a case where it is determined that there is no radio resource corresponding to the measurement.

[0169] In the embodiment of the application, in a case where the terminal does not perform measurement and there is no unreleased radio resource, the carrier aggregation module 200 determines that there is no radio resource corresponding to the measurement, plans the second radio resource application time, and reinitiates the application of the radio resource.

[0170] S816, the carrier aggregation module 200 notifies the radio management module 300 of the second radio resource application time.

[0171] S817, the radio management module 300 initiates the application of the radio resource to the radio chip according to the second radio resource application time, determines the radio resource allocated by the radio chip as the second radio resource, and adjusts the current radio resource configuration of the terminal according to the second radio resource.

[0172] S818, the radio management module 300 notifies the interrupt management module 500 to initiate the interrupt to the current serving cell to interrupt the data service on the current serving cell.

[0173] S819, the radio management module 300 feeds back to the carrier aggregation module 200 that the application of the second radio resource is successful.

[0174] The processes of S817-S819 are consistent with the process described in S808-S809, and will not be described here.

[0175] S820, the carrier aggregation module 200 activates the added first secondary cell by using the second radio resource, and feeds back to the configuration management module 100 that the activation of the first secondary cell is completed, so that the configuration management module 100 updates the state of the first secondary cell in the configuration database. The configuration database contains the state of each secondary cell in the current secondary cell set of the terminal.

[0176] It should be noted that after S814, the carrier aggregation module determines to activate the first secondary cell by using the radio resource corresponding to the measurement in a case where it is determined that there is the radio resource corresponding to the measurement.

[0177] S821, the carrier aggregation module 200 determines the first secondary cell to be in the activated state.

[0178] Herein, the embodiments of the present application do not limit the execution order of S820 and S821.

[0179] In some embodiments, taking the case that the current serving cell includes 1 Pcell and 3 activated SCells, and 1 new SCell needs to be added and activated, the applicant compares the control method of the radio frequency application provided by the embodiments of the present application with related technologies, and the comparison data is shown in Table 2, as follows:

[0180] Table 2

[0181]

[0182] As can be seen from Table 2, the number of service interruptions of the method of the embodiments of the present application is 0 in the SCell addition stage, and the number of service interruptions is 0 in the SCell activation stage when the terminal is performing ongoing measurement. This data shows that the number of service interruptions of the embodiments of the present application is less, and the data stability is better. By comparing the total number of interruptions of the embodiments of the present application in each stage and each case with the total number of interruptions of related technologies in each stage and each case, taking one measurement as an example, the number of interruptions caused by related technologies in the addition, measurement and activation of one secondary cell is as high as 44 times, while the number of interruptions of the embodiments of the present application is only 20 times, which is reduced by 24 times, reaching a total yield ratio of 54.5%.

[0183] It should be noted that for multiple operation coexistence (adding one SCell while activating another SCell, etc.) scenarios, based on the above-mentioned embodiments of the present application Figure 8 The module interaction process shown in the figure can be integrated and uniformly planned by increasing a multi-CC coordination module for resource application and interruption operation.

[0184] It can be understood that the embodiments of the present application flexibly plan the radio frequency resource application time point according to different service scenarios and stages, thereby reducing the impact on the activated cell. Moreover, by connecting the measurement module, the carrier aggregation module and the radio frequency management module, the resource adjustment action is triggered by different modules in different stages, and the results are synchronized, thereby realizing the uniform planning of the radio frequency resource adjustment, reducing the number of service interruptions and improving the stability of the service on the terminal.
