[0063] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0064] In LTE, the terminal device will report historical information to the base station. Specifically, the terminal device will report the 16 most recent cells and the length of time it has stayed. Since the terminal device is mobile, the terminal device may have a large amount of historical information, and the terminal device will report historical information to different base stations, resulting in the base station being unable to obtain comprehensive historical information; secondly, in 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; in addition, if the terminal device changes state and the base station cannot obtain the identification information of the terminal device, the base station will be unable to perform statistical analysis on multiple historical information reported by the same terminal device.

[0065] Due to the above factors, the base station cannot accurately obtain the information of the cell where the terminal device is likely to reside in the future, which will lead to unreasonable scheduling of base station resources. 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 efficiency of the communication system. Among them, RNA (RAN-based Notification Area) means RAN-based notification area.

[0066] Based on this, the present application provides a communication method, the core idea of ​​which is: by utilizing the ability of the terminal device to obtain more comprehensive historical information, the terminal device performs statistical analysis based on its own historical information, obtains permanent area prediction information, and sends the permanent area prediction information to the base station, so that the base station can obtain permanent area prediction information with higher accuracy. Afterwards, the base station can perform operations such as reasonable resource scheduling based on the obtained permanent area prediction information.

[0067] In the present application, the terminal device can obtain comprehensive historical information, and the resident area prediction information obtained by the terminal device based on its own historical information is more accurate; in addition, the terminal device sends the more accurate resident area prediction information to the base station. Compared with the method of reporting historical information by the terminal device in the prior art, the scheme of the present application not only enables the base station to obtain more accurate resident prediction information, but also greatly reduces the signaling overhead caused by the terminal device reporting historical information.

[0068] The following is a brief introduction to the implementation environment involved in the embodiments of the present application.

[0069] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: GSM (Global System of Mobile communication) system, CDMA (Code Division Multiple Access) system, WCDMA (Wideband Code Division Multiple Access) system, GPRS (General Packet Radio Service), LTE (Long Term Evolution) system, LTE FDD (Frequency Division Duplex) system, LTE TDD (Time Division Duplex) system, LTE-A (Advanced long term evolution) system, NR (New Radio) system, NR system evolution system, LTE-U (LTE-Based Access To Unlicensed Spectrum) system, NR-U (NR-Based Access To Unlicensed Spectrum) system, UMTS (Universal Mobile Telecommunication System), WiMAX (Worldwide Interoperability for Microwave Access (Global Interconnected Microwave Access) communication system, WLAN (Wireless Local Area Networks), WiFi (Wireless Fidelity), next generation communication system or other communication systems, etc.

[0070] However, with the development of communication technology, 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.

[0071] The system architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person of ordinary skill in the art can appreciate that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0072] For example, the communication system 100 used in the embodiment of the present application is as follows: Figure 1 The communication system 100 may include a network device 110, and the network device 110 may be a device for communicating with a terminal device 120 (or referred to as a communication terminal or terminal).

[0073] The network device 110 can provide communication coverage for a specific geographical area and can communicate with terminals located in the coverage area. Optionally, the network device 110 can be a base station. The base station (BS) in the embodiment of the present application can also be called a base station device, which is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, the equipment that provides base station functions in 2G networks includes base transceiver stations (BTS for short), the equipment that provides base station functions in 3G networks includes NodeB, the equipment that provides base station functions in 4G networks includes evolved NodeB (eNB), and the equipment that provides base station functions in wireless local area networks (WLAN for short) is access point (AP for short), the equipment that provides base station functions in 5G New Radio (NR for short) is gNB, and the evolving NodeB (ng-eNB), wherein the gNB and the terminal use NR technology for communication, and the ng-eNB and the terminal use E-UTRA (Evolved Universal Terrestrial Radio Access) technology for communication, and both gNB and ng-eNB can be connected to the 5G core network. The base station in the embodiment of the present application also includes equipment that provides base station functions in future new communication systems, etc.

[0074] In addition, the communication system shown in the embodiment of the present application may also include a base station controller (not shown in the figure). The base station controller in the embodiment of the present application is a device for managing base stations, such as a base station controller (BSC) in a 2G network, a radio network controller (RNC) in a 3G network, and may also refer to a device for controlling and managing base stations in future new communication systems.

[0075] The network side network in the embodiment of the present invention refers to a communication network that provides communication services for a terminal, including a base station of a wireless access network, and may also include a base station controller of the wireless access network, and may also include equipment on the core network side.

[0076] The core network described in the embodiments of the present application may be an evolved packet core network (EPC for short), a 5G Core Network (5G Core Network), or a new core network in a future communication system. The 5G Core Network is composed of a group of devices, and implements access and mobility management functions (AMF) that implement mobility management and other functions, user plane functions (UPF) that provide packet routing and forwarding and QoS (Quality of Service) management and other functions, and session management functions (SMF) that provide session management, IP address allocation and management and other functions. The EPC may be composed of an MME that provides mobility management, gateway selection and other functions, a Serving Gateway (S-GW) that provides packet forwarding and other functions, and a PDN Gateway (P-GW) that provides terminal address allocation, rate control and other functions.

[0077] For MBS services, the core network may include several new network elements to implement functions such as data packet forwarding, MBS session management, QoS management, transmission mode switching (switching between unicast and multicast / broadcast transmission modes), etc. Another way is that the functions can be implemented by network elements in the existing core network.

[0078] The communication system 100 also includes at least one terminal device 120 located within the coverage of the network device 110. The terminal in the embodiment of the present application may refer to various forms of user equipment (UE), access terminal, user unit, user station, mobile station, mobile station (MS), remote station, remote terminal, mobile device, user terminal, terminal equipment, wireless communication equipment, user agent or user device.

[0079] Figure 1 The example shows a situation of a network device and a terminal device. It should be understood that the device with communication function in the network / system in the embodiment of the present application can be called a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above and will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0080] The communication method provided by the present application is described in detail below through several specific embodiments.

[0081] Figure 2 This is a flow chart of the first embodiment of the communication method provided by this application. Figure 2 As shown, the method of this embodiment includes:

[0082] S201. The terminal device sends the resident area prediction information of the terminal device to the base station, wherein the resident area prediction information includes: prediction information of the cell and / or TA where the terminal device resides.

[0083] Among them, the resident area prediction information includes the prediction information of the resident cell / tracking area corresponding to the terminal device. Specifically, the resident area prediction information includes the identifier of the predicted resident cell and / or TA and the prediction information of each resident cell and / or TA. Among them, the identifier of the resident cell and / or TA is, for example, the name, ID and other identifiers of the resident cell and / or TA; exemplarily, in the NR system, the identifier of the cell can be the NR cell global identifier (Cell Global Identifier, CGI), wherein the NR CGI is composed of the NR cell ID and the public land mobile network (public land mobile network, PLMN) ID; in the E-UTRA system, the identifier of the cell can be composed of the E-UTRA cell ID and the PLMN ID. The identifier of the TA can be represented by a tracking area identity (tracking area identity, TAI) or a tracking area code (tracking area code, TAC), wherein the TAI is composed of the PLMN ID and the TAC.

[0084] Here, "resident" means that the terminal device is more likely to reside in the future, and the resident cell and / or TA can be determined by one or more of the predicted probability of residence, the predicted length of residence time, and the predicted connection state. Of course, the resident cell and / or TA can also be determined based on other prediction data.

[0085] Optionally, the prediction information of the permanent cell and / or TA may include: one or a combination of: the time period during which the terminal device resides in the permanent cell and / or TA, the length of time the terminal device resides in the permanent cell and / or TA, and the probability of the terminal device residing in the permanent cell and / or TA.

[0086] Exemplarily, the time period during which the terminal device resides in the resident cell and / or TA is, for example, N hours starting from the current time, where N is greater than 0; the length of time during which the terminal device resides in the resident cell and / or TA is, for example, the time period from 9:00 to 18:00 from Monday to Friday; and the probability of the terminal device residing in the resident cell and / or TA is, for example, 50%. This is only an example and does not limit the prediction information of the resident cell and / or TA.

[0087] It should be noted that the prediction information of the permanent cell and / or TA includes the time period during which the terminal device resides in the permanent cell and / or TA, the length of time the terminal device resides in the permanent cell and / or TA, and the probability of the terminal device residing in the permanent cell and / or TA, which are all prediction data obtained by the terminal device based on the historical information of the terminal device.

[0088] It should be understood that if there are multiple permanent cells and / or TAs, the prediction information corresponding to the multiple cells and / or TAs may be different.

[0089] In addition, the present application does not limit the data format of the resident area prediction information, which may be in the form of a data list, or in the form of a text, or in other forms.

[0090] In a possible implementation, the terminal device may obtain the prediction information of the resident area of ​​the terminal device based on historical information such as the cell where the terminal device resides, historical location information of the terminal device, length of time resided in the cell where the terminal device resides, time period resided in the cell where the terminal device resides, current signal quality, current connection status, etc., and through a pre-set related algorithm. Optionally, the above historical information may be historical information of the terminal device within a preset time period, and the preset time period may be, for example but not limited to, 1 year, 1 quarter, 1 month, 1 week, etc.

[0091] Specifically, the terminal device obtains prediction data corresponding to each cell and / or TA in which the terminal device has resided based on the historical information of the terminal device and information such as the current signal quality and the current connection status. The prediction data may include: one or a combination of the probability of residence, the length of residence time, and the time period of residence; based on the prediction data corresponding to each cell and / or TA in which the terminal device has resided, the permanent cell and / or TA is determined; and based on the permanent cell and / or TA and the prediction data corresponding to the permanent cell and / or TA, the permanent area prediction information is obtained.

[0092] Among them, according to the residence probability and / or residence time length corresponding to each cell and / or TA that has been resided, determining the resident cell and / or TA can be achieved in the following manner:

[0093] In a possible implementation, the terminal device determines the resident cell and / or TA according to the resident probability corresponding to each resident cell and / or TA and the first preset threshold. For example, the resident cell and / or TA is a cell and / or TA in which the terminal device has resided and the resident probability is greater than the first preset threshold.

[0094] In another possible implementation, the terminal device determines the resident cell and / or TA according to the length of time of residence corresponding to each resident cell and / or TA and the second preset threshold. For example, the resident cell and / or TA is a cell and / or TA in which the terminal device has resided and the length of time of residence is greater than the second preset threshold.

[0095] In another possible implementation, the terminal device jointly determines the resident cell and / or TA according to the resident probability and resident time length corresponding to each resident cell and / or TA. Exemplarily, the resident cell and / or TA is a cell and / or TA in which the terminal device has resided, where the probability of resident is greater than a first preset threshold, and the length of resident time is greater than a second preset threshold.

[0096] In the above manner, the first preset threshold value may be configured on the network side, or may be agreed upon in the protocol, or may be determined by the terminal device itself, and the embodiments of the present application do not limit this. The second preset threshold value may be configured on the network side, or may be agreed upon in the protocol, or may be determined by the terminal device itself, and the embodiments of the present application do not limit this.

[0097] Optionally, the terminal device obtains prediction data corresponding to each cell and / or TA in which the terminal device has resided based on historical information of the terminal device and information such as current signal quality and current connection status, wherein the prediction data may also include: connection status, where the connection status may be connected state, idle state, and deactivated state.

[0098] The resident cell and / or TA can also be determined according to the connection state of each resident cell and / or TA. Specifically, the resident cell and / or TA can be a cell and / or TA in which the terminal device has resided and whose connection state is connected.

[0099] Optionally, the resident cell and / or TA may also be related to the scenario in which the terminal device is located. For example, the resident cell and / or TA is a cell and / or TA whose switching probability meets preset conditions when the terminal device performs cell switching, wherein the switching probability can be obtained based on the prediction data of the cell and / or TA obtained by the terminal device in which it has resided, such as the probability of residence. For example, the resident cell and / or TA is the SCG when the terminal device enters the DC mode. That is to say, the resident area prediction information may include information about the target cell that the terminal device is most likely to switch to in the current cell or information about a list of service cells controlled by the secondary base station that enters the dual-link state.

[0100] It should be noted that, in some cases, SCG can also be called a second cell group, a serving cell group controlled by a secondary base station, etc. A secondary base station can also be called a secondary base station, a second base station, etc.

[0101] Optionally, the terminal device may report the resident area prediction information to the base station through SRB1, SRB2, and SRB3. Exemplarily, the terminal device may send the resident area prediction information to the base station through one or more of the RRC Setup Complete message, RRC Resume Complete message, RRC Reconfiguration Complete message, RRC Connection Establishment Request message, UE Assistance Information, UL Information Transfer, UL Information Transfer MRDC for dual link, and UE Information Response.

[0102] In a possible implementation, if the resident area prediction information includes multiple sets of resident area prediction information, the terminal device may report the multiple sets of resident area prediction information to the base station. The multiple sets of resident area prediction information may be resident area prediction information corresponding to different time periods determined by the terminal device according to historical information.

[0103] In this embodiment, the terminal device sends the resident area prediction information of the terminal device to the base station, and the resident area prediction information includes: prediction information of the resident cell and / or TA; accordingly, the base station receives the resident area prediction information sent by the terminal device. In this embodiment, the terminal device can obtain comprehensive historical information, and the resident area prediction information obtained by the terminal device based on its own historical information is more accurate; in addition, the terminal device sends the resident area prediction information with higher accuracy to the base station. Compared with the method of reporting historical information by the terminal device in the prior art, the solution of this application not only enables the base station to obtain resident area prediction information with higher accuracy, but also greatly reduces the signaling overhead caused by the terminal device reporting historical information.

[0104] Figure 3 This is a flow chart of Embodiment 2 of the communication method provided by this application. Figure 3 As shown, the method of this embodiment includes:

[0105] S301. The terminal device determines whether information reporting conditions are met.

[0106] If the terminal device determines that the information reporting conditions are met, S302 is executed.

[0107] In a possible implementation, the information reporting condition is: the terminal device is located in a permanent cell and / or TA.

[0108] In another possible implementation, the information reporting condition is: the terminal device is located in a permanent cell and / or TA, and the terminal device is in a connected state.

[0109] Another possible implementation method is that the information reporting condition is: the terminal device is located in the permanent cell and / or the neighboring cell of the TA.

[0110] Another possible implementation method is that the information reporting condition is: the terminal device is located in the permanent cell and / or the neighboring cell of the TA, and the terminal device is in a connected state.

[0111] In the above-mentioned possible implementation methods, the terminal device can determine whether the terminal device is located in the permanent cell and / or TA based on the location information of the permanent 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 permanent cell and / or the neighboring area of ​​the resident cell and / or TA based on the location information of the neighboring area of ​​the permanent cell and / or TA and the location of the terminal device itself.

[0112] It should be noted that the information reporting conditions in the embodiments of the present application are not limited to the above-mentioned ones, and the terminal device can set different information reporting conditions in different scenarios to achieve dynamic adjustment of the information reporting conditions, thereby improving the flexibility of information reporting.

[0113] For example, from 7:00 to 9:00 on weekdays, users may be on their way to work and the mobility of their terminal devices is relatively strong. Therefore, the information reporting condition may be that the terminal device is located in the permanent cell and / or the TA's neighboring cell; from 9:00 to 18:00 on weekdays, users are usually at their workplaces and the mobility of their terminal devices is relatively low. Therefore, the information reporting condition may be that the terminal device is located in the permanent cell and / or the TA.

[0114] S302. The terminal device sends the resident area prediction information of the terminal device to the base station.

[0115] In this embodiment, S302 and Figure 2 S201 in the embodiment shown is similar, and can be referred to Figure 2 The detailed description in the illustrated embodiment will not be repeated here.

[0116] In this solution, when the terminal device determines that the information reporting conditions are met, it sends the permanent area prediction information of the terminal device to the base station, so that the base station obtains the permanent area prediction information with higher accuracy, which meets the needs of the base station; in addition, the solution in this embodiment can also greatly reduce the signaling overhead of the terminal device reporting the permanent area prediction information.

[0117] Figure 4 This is a flow chart of Embodiment 3 of the communication method provided by this application. The method shown in this embodiment is Figure 2 Based on the embodiment shown, after S201, the following steps may also be included:

[0118] S202. The base station performs one or a combination of measurement configuration, switching strategy, dual connection configuration, and RNA configuration according to the resident area prediction information.

[0119] Specifically, the base station can perform one or a combination of measurement configuration, switching strategy, dual connection configuration and RNA configuration according to the resident area prediction information, thereby improving system efficiency and reducing overhead such as terminal equipment measurement and cell switching behavior.

[0120] Exemplarily, the base station may configure the terminal device to measure one or more neighboring cells included in the resident area prediction information of the current serving cell, thereby reducing the measurement and reporting overhead of the terminal device and saving power of the terminal device and the base station.

[0121] In addition, if the resident area prediction information reported by the terminal device includes multiple sets of resident area prediction information, and the multiple sets of resident area prediction information can be for different time periods or different time periods, the base station can implement different radio resource management (radio resource management, RRM) strategies in different time periods according to the multiple sets of permanent area prediction information, thereby improving system efficiency.

[0122] It should be understood that for each set of permanent area prediction information, the operations performed by the base station in different time periods may be the same or different. For example, the first set of permanent area prediction information is for 7:00-9:00 on weekdays, and the second set of permanent area prediction information is for 9:00-18:00 on weekdays. The base station may perform different operations at 7:00-9:00 and 9:00-18:00 on weekdays.

[0123] In this embodiment, the terminal device predicts the permanent area where it may reside in the future and reports it to the network side. The network side can implement reasonable RRM strategies based on the information of the permanent area where the terminal device may reside in the future, reduce signaling overhead, thereby improving system efficiency and improving the measurement, mobility, energy saving and other performance of the terminal device.

[0124] Figure 5 This is a flow chart of the fourth embodiment of the communication method provided by this application. After the terminal device obtains the resident area prediction information, it can Figures 2 to 4 The resident area prediction information is actively reported to the base station in the manner shown, or the resident area prediction information is reported to the base station after receiving the instruction to report the resident area prediction information sent by the base station as shown in this embodiment. Figure 5 As shown, the method of this embodiment includes:

[0125] S401. The terminal device sends first indication information to the base station, wherein the first indication information is used to indicate that resident area prediction information exists in the terminal device.

[0126] Correspondingly, the base station receives the first indication information sent by the terminal device.

[0127] Specifically, in this embodiment, after the terminal device obtains the resident area prediction information, it can instruct the base station that there is resident area prediction information to report.

[0128] Exemplarily, the terminal device may carry the above-mentioned first indication information in an RRC message to indicate to the base station that the terminal device has reportable resident area prediction information.

[0129] Optionally, in addition to the information used to indicate the existence of resident area prediction information in the terminal device, the first indication information may also include time information and probability information. The time information referred to here may be determined based on the length of time the terminal device resides in the resident cell and / or TA and / or the time period the terminal device resides in the resident cell and / or TA; the probability information referred to here may be determined based on the probability of the terminal device residing in the resident cell and / or TA. This step can be performed by uploading coarse-grained resident area prediction information, and the base station can reasonably determine whether the terminal device needs to report the resident area prediction information based on the first indication information, thereby improving system efficiency.

[0130] In a possible implementation, the terminal device may send the first indication information to the base station when determining that the information reporting condition is met. Optionally, the information reporting condition may be that the terminal device is located in a resident cell and / or TA, or that the terminal device is located in a resident cell and / or TA and the terminal device is in a connected state, or that the terminal device is located in a neighboring cell of the resident cell and / or TA, or that the terminal device is located in a neighboring cell of the resident cell and / or TA and the terminal device is in a connected state.

[0131] In the above-mentioned possible implementation methods, the terminal device can determine whether the terminal device is located in the permanent cell and / or TA based on the location information of the permanent 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 permanent cell and / or the neighboring area of ​​the resident cell and / or TA based on the location information of the neighboring area of ​​the permanent cell and / or TA and the location of the terminal device itself.

[0132] It should be noted that the information reporting conditions in the embodiments of the present application are not limited to the above-mentioned ones, and the terminal device can set different information reporting conditions in different scenarios to achieve dynamic adjustment of the information reporting conditions, thereby improving the flexibility of information reporting.

[0133] For example, from 7:00 to 9:00 on weekdays, users may be on their way to work and the mobility of their terminal devices is relatively strong. Therefore, the information reporting condition may be that the terminal device is located in the permanent cell and / or the TA's neighboring cell; from 9:00 to 18:00 on weekdays, users are usually at their workplaces and the mobility of their terminal devices is relatively low. Therefore, the information reporting condition may be that the terminal device is located in the permanent cell and / or the TA.

[0134] S402. The base station sends second indication information to the terminal device, wherein the second indication information is used to instruct the terminal device to report the resident area prediction information.

[0135] Correspondingly, the terminal device receives the second indication information sent by the base station.

[0136] The base station instructs the terminal device to report the resident area prediction information through the second indication information, for example, instructs the terminal device to report the resident area prediction information in the UEinformation request.

[0137] S403: The terminal device sends resident area prediction information to the base station.

[0138] Step S403 in this embodiment is Figure 2 S201 in the illustrated embodiment is similar, and reference may be made to the detailed description of the terminal device sending the resident area prediction information to the base station in S201, which will not be repeated here.

[0139] In this embodiment, the terminal device can send a first indication information to the base station when the information reporting conditions are met, and reasonably report the permanent area prediction information based on the second indication information sent by the base station. The method of this embodiment can effectively reduce the signaling overhead of the air interface reporting of the permanent area prediction information.

[0140] Figure 6 Flowchart of Embodiment 5 of the communication method provided in this application. In some scenarios, the terminal device reports the resident area prediction information. Since the terminal device has mobility, the terminal device may need to perform cell switching or serving base station switching. In such a case, the embodiment of this application details how the target base station obtains accurate resident area prediction information.

[0142] S501. A terminal device sends prediction information of a resident area of ​​the terminal device to a base station.

That is, the source base station sends the resident area prediction information to the target base station. Afterwards, the target base station can implement a corresponding handover strategy according to the resident area prediction information.

[0147] When the terminal device is in DC mode, if the base station that receives the resident area prediction information sent by the terminal device in S501 is the main 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 main base station in the DC mode.

[0148] In a possible implementation manner, if the base station determines that the resident cell and / or TA included in the resident area prediction information includes the target base station, the base station sends the resident area prediction information to the target base station.

[0149] In this embodiment, after receiving the resident area prediction information sent by the terminal device, the base station can send the resident area prediction information to the target base station based on the current state of the terminal device, so that the associated base stations can obtain the resident area prediction information with high accuracy; 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, this embodiment realizes that the base station and the target base station obtain accurate resident area prediction information, while greatly reducing the signaling overhead.
