[0085] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the protection scope of this application.

[0086] In LTE, a terminal device reports historical information to a base station. Specifically, the terminal device reports the most recent 16 cells and the duration of residence. Since the terminal device has mobility, the historical information of the terminal device may be large in quantity, and the terminal device reports historical information to different base stations, resulting in the base station being unable to obtain comprehensive historical information. Secondly, in the dual-connection DC mode, the terminal device only reports the information of the primary cell, and the historical information reported by the terminal device is not comprehensive enough. Additionally, if the status of the terminal device changes and the base station cannot obtain the identification information of the terminal device, the base station will be unable to perform statistical analysis on the multiple historical information reported by the same terminal device.

[0087] Due to the above-mentioned factors in multiple aspects, the base station is unable to accurately obtain the information of the cell where the terminal device is likely to reside in the future, which will further lead to unreasonable resource scheduling of the base station. For example, the configuration of RNA, measurement configuration, DC configuration, etc. is relatively rough. If the terminal device reports historical information to all base stations, the signaling overhead of reporting historical information will be large, reducing the communication system efficiency. Among them, RNA (RAN-based Notification Area) represents the RAN-based notification area.

[0088] Based on this, this application provides a communication method. The core idea of this communication method is that by utilizing the ability of the terminal device to obtain relatively comprehensive historical information, the terminal device performs statistical analysis based on its own historical information to obtain the predicted information of the resident area, and sends the predicted information of the resident area to the base station to enable the base station to obtain the predicted information of the resident area with relatively high accuracy. After that, the base station can perform operations such as reasonable resource scheduling based on the obtained predicted information of the resident area.

[0089] In this application, the terminal device can obtain comprehensive historical information, and the accuracy of the predicted residence area information obtained by the terminal device based on its own historical information is higher. In addition, the terminal device sends the predicted residence area information with higher accuracy to the base station. Compared with the way in the prior art where the terminal device reports historical information, the solution of this application not only enables the base station to obtain the predicted residence information with higher accuracy, but also greatly reduces the signaling overhead caused by the terminal device reporting historical information.

[0090] The implementation environment involved in the embodiments of this application will be briefly introduced below.

[0091] The technical solutions of the embodiments of this application can be applied to various communication systems, such as: GSM (Global System of Mobile communication), CDMA (Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), GPRS (General Packet Radio Service), LTE (Long Term Evolution), LTE FDD (Frequency Division Duplex), LTE TDD (Time Division Duplex), LTE-A (Advanced long term evolution), NR (New Radio), the evolved system of the NR system, LTE-U (LTE-Based Access To Unlicensed Spectrum), NR-U (NR-Based Access To Unlicensed Spectrum), UMTS (Universal Mobile Telecommunication System), WiMAX (Worldwide Interoperability for Microwave Access), WLAN (Wireless Local Area Networks), WiFi (Wireless Fidelity), the next-generation communication system or other communication systems, etc.

[0092] However, with the development of communication technologies, mobile communication systems will not only support traditional communications, but also support, for example, D2D (Device to Device) communication, M2M (Machine to Machine) communication, MTC (Machine Type Communication), V2V (Vehicle to Vehicle) communication, and V2X (Vehicle to Everything) systems, etc. The embodiments of the present application can also be applied to these communication systems. In addition, the embodiments of the present application can also be applied to system architectures such as relay network architectures and dual-connection structures.

[0093] The system architectures and service scenarios described in the embodiments of the present application are for more clearly explaining the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art can understand that with the evolution of network architectures and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

[0094] Exemplarily, the communication system 100 to which the embodiments of the present application are applied is as Figure 1 shown. The communication system 100 may include a network device 110, and the network device 110 may be a device that communicates with a terminal device 120 (or referred to as a communication terminal, terminal).

[0095] The network device 110 can provide communication coverage for a specific geographical area and can communicate with terminals located within the coverage area. Optionally, the network device 110 can be a base station. The base station (abbreviated as BS) in the embodiments of this application can also be referred to as base station equipment, which is a device deployed in the radio access network (RAN) to provide wireless communication functions. For example, the device providing base station functions in the 2G network includes the base transceiver station (abbreviated as BTS in English), the device providing base station functions in the 3G network includes Node B, the device providing base station functions in the 4G network includes the evolved Node B (eNB), in the wireless local area networks (abbreviated as WLAN), the device providing base station functions is the access point (abbreviated as AP), the device providing base station functions in 5G New Radio (abbreviated as NR) is the gNB, and the next-generation evolved Node B (ng-eNB). Among them, the gNB and the terminal communicate using NR technology, and the ng-eNB and the terminal communicate using E-UTRA (Evolved Universal Terrestrial Radio Access) technology. Both the gNB and the ng-eNB can be connected to the 5G core network. The base station in the embodiments of this application also includes devices providing base station functions in future new communication systems, etc.

[0096] In addition, a base station controller (not shown in the figure) can also be included in the communication system shown in the embodiments of this application. The base station controller in the embodiments of this application is a device for managing base stations. For example, the base station controller (abbreviated as BSC) in the 2G network, the radio network controller (abbreviated as RNC) in the 3G network, and can also refer to the device for controlling and managing base stations in future new communication systems.

[0097] The network side network in the embodiments of the present invention refers to the communication network that provides communication services for terminals, including the base stations in the radio access network, and can also include the base station controllers in the radio access network, and can also include the devices on the core network side.

[0098] In the embodiments of the present application, the core network may be an evolved packet core (EPC), a 5G Core Network, or a new core network in future communication systems. The 5G Core Network consists of a set of devices and implements functions such as access and mobility management function (AMF) for mobility management, user plane function (UPF) for providing packet routing and forwarding and QoS (Quality of Service) management, session management function (SMF) for providing session management, IP address allocation and management, etc. The EPC may be composed of an MME that provides functions such as mobility management and gateway selection, a Serving Gateway (S-GW) that provides functions such as packet forwarding, and a PDN Gateway (P-GW) that provides functions such as terminal address allocation and rate control.

[0099] For MBS services, several new network elements may be included in the core network to implement functions such as packet forwarding, MBS session management, QoS management, and transmission mode switching (switching between unicast and multicast / broadcast transmission modes). Another way is that the functions can be implemented by network elements in the existing core network.

[0100] The communication system 100 further includes at least one terminal device 120 within the coverage area of the network device 110.

[0101] Figure 1 Exemplarily, the situation of one network device and one terminal device is shown. It should be understood that the devices with communication functions in the network / system in the embodiments of the present application may be referred to as communication devices. Taking Figure 1 the shown communication system 100 as an example, the communication devices may include the network device 110 and the terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above, which will not be elaborated here; the communication devices may also include other devices in the communication system 100, such as network controllers, mobile management entities and other network entities. The embodiments of the present application are not limited thereto.

[0102] Next, through several specific embodiments, the communication method provided by the present application will be introduced in detail.

[0103] Figure 2 This is the flowchart of the first embodiment of the communication method provided by the present application. As Figure 2 shown, the method of this embodiment includes:

[0104] S201. The terminal device sends the prediction information of the terminal device's resident area to the base station, where the prediction information of the resident area includes: the prediction information of the cell and / or TA where the terminal device resides.

[0105] Among them, the prediction information of the resident area includes the prediction information of the resident cell / tracking area corresponding to the terminal device. Specifically, the prediction information of the resident area includes the identifiers of the predicted resident cells and / or TAs, and the prediction information of each resident cell and / or TA. Among them, the identifiers of the resident cells and / or TAs are, for example, the names, IDs, etc. of the resident cells and / or TAs; exemplarily, in the NR system, the identifier of a cell can be the NR Cell Global Identifier (CGI), where the NR CGI is composed of the NR cell ID and the Public Land Mobile Network (PLMN) ID; in the E-UTRA system, the identifier of a cell can be composed of the E-UTRA cell ID and the PLMN ID. The identifier of a TA can be represented by the Tracking Area Identity (TAI) or the Tracking Area Code (TAC), where the TAI is composed of the PLMN ID and the TAC.

[0106] Here, "resident" means that the terminal device has a relatively high probability of staying in the future. The resident cells and / or TAs can be determined by one or more of the predicted residence probability, the predicted residence time length, and the predicted connection status. Of course, the resident cells and / or TAs can also be determined according to other prediction data.

[0107] Optionally, the prediction information of the resident cells and / or TAs may include: one or a combination of the time period during which the terminal device stays in the resident cells and / or TAs, the time length during which the terminal device stays in the resident cells and / or TAs, and the probability that the terminal device stays in the resident cells and / or TAs.

[0108] Exemplarily, the time period during which the terminal device stays in the resident cells and / or TAs is, for example: N hours starting from the current moment, where N > 0; the time length during which the terminal device stays in the resident cells and / or TAs is, for example, the time period from 9:00 to 18:00 from Monday to Friday; the probability that the terminal device stays in the resident cells and / or TAs is, for example: 50%. This is only an example and does not limit the prediction information of the resident cells and / or TAs.

[0109] It should be noted that the time period during which the terminal device stays in the resident cells and / or TAs, the time length during which the terminal device stays in the resident cells and / or TAs, and the probability that the terminal device stays in the resident cells and / or TAs included in the prediction information of the resident cells and / or TAs are all prediction data obtained by the terminal device based on the historical information of the terminal device.

[0110] It should be understood that if there are multiple resident cells and / or TAs, there may be differences between the prediction information corresponding to the multiple cells and / or TAs respectively.

[0111] In addition, the data format of the prediction information for the resident area in this application is not limited. It can be in the form of a data list, or it can be in the form of text, or it can also be in other forms.

[0112] In a possible implementation manner, the terminal device can obtain the prediction information of the resident area of the terminal device according to historical information such as the cells where the terminal device has camped, the historical location information of the terminal device, the length of time of camping in the cells where it has camped, the time period of camping in the cells where it has camped, etc., the current signal quality, the current connection status, etc., and through a preset related algorithm. Optionally, the above historical information can be the historical information of the terminal device within a preset time period, and the preset time period can be, for example, but not limited to, 1 year, 1 quarter, 1 month, 1 week, etc.

[0113] Specifically, the terminal device obtains, according to the historical information of the terminal device and information such as the current signal quality and the current connection status, the prediction data corresponding to each of the cells and / or TAs where the terminal device has camped. The prediction data may include: one or a combination of the probability of camping, the length of time of camping, and the time period of camping; determines the resident cells and / or TAs according to the prediction data corresponding to each of the cells and / or TAs where it has camped; and obtains the prediction information of the resident area according to the resident cells and / or TAs and the prediction data corresponding to the resident cells and / or TAs.

[0114] Among them, determining the resident cells and / or TAs according to the camping probability and / or the length of time of camping corresponding to each of the cells and / or TAs where it has camped can be implemented in the following manner:

[0115] In a possible implementation manner, the terminal device determines the resident cells and / or TAs according to the camping probability corresponding to each of the cells and / or TAs where it has camped and a first preset threshold. For example, the resident cells and / or TAs are the cells and / or TAs where the camping probability is greater than the first preset threshold among the cells and / or TAs where the terminal device has camped.

[0116] In another possible implementation manner, the terminal device determines the resident cells and / or TAs according to the length of time of camping corresponding to each of the cells and / or TAs where it has camped and a second preset threshold. For example, the resident cells and / or TAs are the cells and / or TAs where the length of time of camping is greater than the second preset threshold among the cells and / or TAs where the terminal device has camped.

[0117] In another possible implementation, the terminal device jointly determines the resident cell and / or TA according to the residence probability and residence duration corresponding to each cell and / or TA where it has camped. Exemplarily, the resident cell and / or TA are the cells and / or TAs where the terminal device has camped, and the residence probability is greater than a first preset threshold, and the residence duration is greater than a second preset threshold.

[0118] In the above method, the first preset threshold may be configured by the network side, or may be agreed upon by the protocol, or may also be determined by the terminal device itself. The embodiments of the present application do not limit this. The second preset threshold may be configured by the network side, or may be agreed upon by the protocol, or may also be determined by the terminal device itself. The embodiments of the present application do not limit this.

[0119] Optionally, the terminal device obtains the prediction data corresponding to each cell and / or TA where it has camped according to the historical information of the terminal device, the current signal quality, the current connection status, etc. The prediction data may further include: the connection status, where the connection status may be the connected state, the idle state, and the deactivated state.

[0120] Then, the resident cell and / or TA may also be determined according to the connected state of each cell and / or TA where it has camped. Specifically, the resident cell and / or TA may be the cells and / or TAs where the terminal device has camped, and the connection status is the connected state.

[0121] Optionally, the resident cell and / or TA may also be related to the scenario where the terminal device is located. For example, the resident cell and / or TA are the cells and / or TAs where the switching probability meets the preset conditions when the terminal device performs cell switching, where the switching probability may be obtained according to the prediction data of the cells and / or TAs where the terminal device has camped, such as the residence probability. For example, the resident cell and / or TA are the SCG when the terminal device enters the DC mode. That is to say, the resident area prediction information may include the information of the target cell that the terminal device is most likely to switch to in the current cell or the information of the list of serving cells controlled by the secondary base station when entering the dual-link state.

[0122] It should be noted that in some cases, the SCG may also be referred to as other names such as the second cell group and the service cell group controlled by the secondary base station. The secondary base station may also be referred to as other names such as the secondary base station and the second base station.

[0123] Optionally, the terminal device may report the predicted information of the resident area to the base station through SRB1, SRB2, SRB3, etc. Exemplarily, the terminal device may send the predicted information of the resident area to the base station through one or more of the RRC setup complete message, RRC resume complete message, RRC reconfiguration complete message, RRC connection setup request message, UE assistance information, UL information transfer, UL information transfer for dual connectivity, and UE information response.

[0124] In a possible implementation, if the predicted information of the resident area includes multiple sets of predicted information of the resident area, the terminal device may report multiple sets of predicted information of the resident area to the base station. Among them, the multiple sets of predicted information of the resident area may be the predicted information of the resident area corresponding to different time periods determined by the terminal device according to historical information.

[0125] In this embodiment, the terminal device sends the predicted information of the resident area of the terminal device to the base station, and the predicted information of the resident area includes: the predicted information of the resident cell and / or TA; correspondingly, the base station receives the predicted information of the resident area sent by the terminal device. In this embodiment, the terminal device can obtain comprehensive historical information, and the predicted information of the resident area obtained by the terminal device according to its own historical information is more accurate; in addition, the terminal device sends the predicted information of the resident area with higher accuracy to the base station. Compared with the method in the prior art where the terminal device reports historical information, the solution of this application not only enables the base station to obtain the predicted information of the resident area with higher accuracy, but also greatly reduces the signaling overhead caused by the terminal device reporting historical information.

[0126] Figure 3 This is the flowchart of the second embodiment of the communication method provided by this application. As Figure 3 shown, the method of this embodiment includes:

[0127] S301. The terminal device determines whether the information reporting condition is satisfied.

[0128] If the terminal device determines that the information reporting condition is satisfied, then S302 is executed.

[0129] In a possible implementation, the information reporting condition is that the terminal device is located in the resident cell and / or TA.

[0130] Another possible implementation manner, the information reporting condition is: the terminal device is located in the resident cell and / or TA, and the terminal device is in the connected state.

[0131] Another possible implementation manner, the information reporting condition is: the terminal device is located in the neighboring cell of the resident cell and / or TA.

[0132] Another possible implementation manner, the information reporting condition is: the terminal device is located in the neighboring cell of the resident cell and / or TA, and the terminal device is in the connected state.

[0133] In the above several possible implementation manners, the terminal device can determine whether the terminal device is located in the resident cell and / or TA according to the location information of the resident cell and / or TA and the location of the terminal device itself; the terminal device can determine whether the terminal device is located in the neighboring cell of the resident cell and / or TA according to the location information of the neighboring cell of the resident cell and / or TA and the location of the terminal device itself.

[0134] It should be noted that the information reporting conditions in the embodiments of the present application are not limited to the above several, and the terminal device can set different information reporting conditions in different scenarios to realize the dynamic adjustment of the information reporting conditions and improve the flexibility of information reporting.

[0135] For example, from 7:00 to 9:00 on weekdays, the user may be on the way to work, and the mobility of the terminal device is relatively strong. Therefore, the information reporting condition can be that the terminal device is located in the neighboring cell of the resident cell and / or TA; from 9:00 to 18:00 on weekdays, the user is usually at the work place, and the mobility of the terminal device is relatively low. Therefore, the information reporting condition can be that the terminal device is located in the resident cell and / or TA.

[0136] S302. The terminal device sends the predicted information of the resident area of the terminal device to the base station.

[0137] In this embodiment, S302 is similar to Figure 2 S201 in the Figure 2 shown embodiment, and reference can be made to the detailed description in the

[0138] shown embodiment, and details are not described herein again.

[0139] Figure 4 This is the flowchart of the third embodiment of the communication method provided by the present application. The method shown in this embodiment is inFigure 2 Based on the illustrated embodiments, after S201, the following may further be included:

[0140] S202. The base station performs one or a combination of measurement configuration, handover strategy, dual-connection configuration, and RNA configuration according to the predicted information on the resident area.

[0141] Specifically, the base station may perform one or a combination of measurement configuration, handover strategy, dual-connection configuration, and RNA configuration according to the predicted information on the resident area, so as to improve system efficiency and reduce the overheads such as the measurement of the terminal device and the cell handover behavior.

[0142] Exemplarily, the base station may configure the terminal device to measure one or more neighboring cells included in the predicted information on the resident area of the current serving cell, thereby reducing the measurement and reporting overheads of the terminal device and saving the electric energy of the terminal device and the base station.

[0143] In addition, if the predicted information on the resident area reported by the terminal device includes multiple sets of predicted information on the resident area, and the multiple sets of predicted information on the resident area may be for different time periods or different time cycles, the base station may implement different radio resource management (RRM) strategies in different time periods according to the multiple sets of predicted information on the resident area, thereby improving system efficiency.

[0144] It should be understood that for each set of predicted information on the resident area, the operations performed by the base station in different time periods may be the same or different. For example, if the first set of predicted information on the resident area is for 7:00 - 9:00 on a working day and the second set of predicted information on the resident area is for 9:00 - 18:00 on a working day, the base station may perform different operations at 7:00 - 9:00 and 9:00 - 18:00 on the working day.

[0145] In this embodiment, the terminal device predicts the possible future resident areas and reports them to the network side. The network side may perform reasonable RRM strategies according to the information on the possible future resident areas predicted by the terminal device, reduce signaling overheads, thereby improving system efficiency and enhancing the performance of the terminal device such as measurement, mobility, and energy saving.

[0146] Figure 5 This is a flowchart of the fourth embodiment of the communication method provided by this application. After the terminal device obtains the predicted information on the resident area, it may actively report the predicted information on the resident area to the base station in the manner as Figures 2 to 4 shown, or may also report the predicted information on the resident area to the base station after receiving the indication to report the predicted information on the resident area sent by the base station as shown in this embodiment. Specifically, as Figure 5 shown, the method of this embodiment includes:

[0147] S401. The terminal device sends first indication information to the base station, where the first indication information is used to indicate that there is resident area prediction information in the terminal device.

[0148] Correspondingly, the base station receives the first indication information sent by the terminal device.

[0149] Specifically, in this embodiment, after the terminal device obtains the resident area prediction information, it can indicate to the base station that there is resident area prediction information to be reported.

[0150] Exemplarily, the terminal device may carry the above first indication information in the RRC message to indicate to the base station that there is reportable resident area prediction information in the terminal device.

[0151] Optionally, in addition to the information used to indicate that there is resident area prediction information in the terminal device, the first indication information may further include time information and probability information. The time information herein may be determined according to the length of time the terminal device stays in the resident cell and / or TA and / or the time period during which the terminal device stays in the resident cell and / or TA; the probability information herein may be determined according to the probability that the terminal device stays in the resident cell and / or TA. In this step, by uploading coarse-grained resident area prediction information, the base station can reasonably determine whether the terminal device needs to report the resident area prediction information according to the first indication information, thereby improving system efficiency.

[0152] A possible implementation manner is that the terminal device may send the first indication information to the base station when it determines that the information reporting condition is met. Optionally, the information reporting condition may be that the terminal device is located in the resident cell and / or TA, or the terminal device is located in the resident cell and / or TA and the terminal device is in the connected state, or the terminal device is located in the neighboring cell of the resident cell and / or TA, or the terminal device is located in the neighboring cell of the resident cell and / or TA and the terminal device is in the connected state.

[0153] In the above several possible implementation manners, the terminal device can determine whether it is located in the resident cell and / or TA according to the location information of the resident cell and / or TA and the location of the terminal device itself; the terminal device can determine whether it is located in the neighboring cell of the resident cell and / or TA according to the location information of the neighboring cell of the resident cell and / or TA and the location of the terminal device itself.

[0154] It should be noted that the information reporting conditions in the embodiments of the present application are not limited to the above several, and the terminal device can set different information reporting conditions in different scenarios to realize the dynamic adjustment of the information reporting conditions, improving the flexibility of information reporting.

[0155] For example, from 7:00 to 9:00 on a working day, the user may be on the way to work and the mobility of the terminal device is relatively high. Therefore, the information reporting condition can be that the terminal device is located in the serving cell and / or the neighboring cell of the TA; from 9:00 to 18:00 on a working day, the user is usually at the work place and the mobility of the terminal device is relatively low. Therefore, the information reporting condition can be that the terminal device is located in the serving cell and / or the TA.

[0156] S402. The base station sends second indication information to the terminal device, where the second indication information is used to instruct the terminal device to report the predicted information of the resident area.

[0157] Correspondingly, the terminal device receives the second indication information sent by the base station.

[0158] Among them, the base station instructs the terminal device to report the predicted information of the resident area through the second indication information. For example, the terminal device is instructed to report the predicted information of the resident area in the UE information request.

[0159] S403. The terminal device sends the predicted information of the resident area to the base station.

[0160] Step S403 in this embodiment is Figure 2 similar to S201 in the

[0161] shown embodiment. The detailed description of the terminal device sending the predicted information of the resident area to the base station in S201 can be referred to, and details are not described here again.

[0162] Figure 6 This is the flowchart of the fifth embodiment of the communication method provided by this application. In some scenarios, when the terminal device reports the predicted information of the resident area, due to the mobility of the terminal device, the terminal device may need to perform cell handover, or serving base station handover, etc. In such a case, this application embodiment details how the target base station obtains accurate predicted information of the resident area.

[0163] As Figure 6 shown, the method of this embodiment includes:

[0164] S501. The terminal device sends the predicted information of the resident area of the terminal device to the base station.

[0165] In this embodiment, when the terminal device sends the predicted information of the resident area of the terminal device to the base station, it can adopt the above Figure 2 and Figure 3In the manner of the embodiment shown, the terminal device directly sends the resident area prediction information to the base station, or when the terminal device determines that the information reporting condition is met, it sends the resident area prediction information to the base station; alternatively, it can also be adopted Figure 5 In the manner of the embodiment shown, when the terminal device determines that the information reporting condition is met, it first sends the first indication information to the base station, and after receiving the second indication information sent by the base station, it sends the resident area prediction information to the base station.

[0166] For details, reference can be made to the detailed descriptions in the above Figure 2 、 Figure 3 and Figure 5 shown embodiments, which will not be elaborated here.

[0167] S502. The base station sends the resident area prediction information to the target base station.

[0168] In the scenario where the terminal device performs a cell handover, the target base station is the target base station when the terminal device performs a cell handover. That is to say, the source base station sends the resident area prediction information to the target base station. After that, the target base station can implement the corresponding handover strategy according to the resident area prediction information.

[0169] When the terminal device is in the DC mode, if the base station that receives the resident area prediction information sent by the terminal device in S501 is the master base station in the DC mode, the target base station is the secondary base station in the DC mode; if the base station that receives the resident area prediction information sent by the terminal device in S501 is the secondary base station in the DC mode, the target base station is the master base station in the DC mode.

[0170] In a possible implementation manner, if the base station determines that the resident cells and / or TAs included in the resident area prediction information include the target base station, the base station sends the resident area prediction information to the target base station.

[0171] In this embodiment, after the base station receives the resident area prediction information sent by the terminal device, it can send the resident area prediction information to the target base station based on the current state of the terminal device, so that relatively accurate resident area prediction information can be obtained among associated base stations; and the target base station can implement the corresponding RRM strategy according to the resident area prediction information, thereby improving the system efficiency. In addition, in this embodiment, on the basis of the base station and the target base station obtaining accurate resident area prediction information, the signaling overhead is greatly reduced.

[0172] Figure 7This is the flowchart of the sixth embodiment of the communication method provided by this application. In some scenarios, the terminal device reports the predicted information of the resident area. Since the terminal device has mobility, the terminal device may need to perform cell handover, or service base station handover, etc. In such cases, after receiving the predicted information of the resident area sent by the terminal device, the source base station can send the predicted information of the resident area to the target base station based on the current state of the terminal device. This application embodiment details how the source base station and the target base station obtain accurate predicted information of the resident area.

[0173] As Figure 7 shown, the method of this embodiment includes:

[0174] S701. The source base station sends the predicted information of the resident area of the terminal device to the target base station.

[0175] Among them, the predicted information of the resident area includes: the predicted information of the resident cell and / or tracking area TA.

[0176] Specifically, the predicted information of the resident cell and / or TA includes: one or a combination of the resident cell and / or TA identifier, the time period for which the terminal device stays in the resident cell and / or TA, the length of time for which the terminal device stays in the resident cell and / or TA, and the probability for which the terminal device stays in the resident cell and / or TA.

[0177] A possible implementation manner is that the source base station receives the first indication information from the terminal device, and the first indication information is used to indicate that there is predicted information of the resident area in the terminal device; the source base station sends the second indication information to the terminal device, and the second indication information is used to indicate that the terminal device reports the predicted information of the resident area.

[0178] A possible implementation manner is that the target base station is the target base station corresponding to the cell handover of the terminal device.

[0179] A possible implementation manner is that the source base station sends the predicted information of the resident area to the secondary base station. The source base station is the primary base station when the terminal device is in the dual-connection DC mode, and the secondary base station is the secondary base station when the terminal device is in the dual-connection DC mode.

[0180] A possible implementation manner is that the source base station sends the predicted information of the resident area to the primary base station. The source base station is the secondary base station when the terminal device is in the DC mode, and the primary base station is the primary base station when the terminal device is in the dual-connection DC mode.

[0181] A possible implementation manner is that the source base station performs one or a combination of measurement configuration, handover strategy, dual-connection configuration, and RNA configuration according to the predicted information of the resident area.

[0182] In a possible implementation, the target base station can implement corresponding RRM policies based on the predicted information of the resident area.

[0183] For the specific execution process, reference can be made to the above embodiments, which will not be elaborated here.

[0184] In this application, the predicted information of the resident area sent by the source base station is the predicted information of the resident area obtained by the terminal device based on its own historical information, and the accuracy of the predicted information of the resident area is higher. In addition, the source base station sends the predicted information of the resident area with higher accuracy to the target base station. The solution of this application not only enables the acquisition of the predicted information of the resident area with higher accuracy between the associated source base station and the target base station, but also greatly reduces the signaling overhead caused by the reporting of historical information between the base stations.
