Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In LTE, the terminal device reports history information to the base station. Specifically, the terminal device reports the latest 16 cells and the length of the residence time. Because the terminal equipment has mobility, the historical information of the terminal equipment is possibly more, and the terminal equipment reports the historical information to different base stations, so that the base stations cannot acquire comprehensive historical information; secondly, when in the dual-connection DC mode, the terminal equipment only reports the information of the main cell, and the history information reported by the terminal equipment is not comprehensive enough; in addition, if the state of the terminal device changes and the base station cannot acquire the identification information of the terminal device, the base station cannot perform statistical analysis on multiple times of history information reported by the same terminal device.

Due to the above factors, the base station cannot accurately acquire information of a cell where the terminal device resides with a high probability in the future, and further, resource scheduling of the base station is unreasonable, for example, configuration of RNA, measurement configuration, DC, and the like are rough. If the terminal device reports the history information to all the base stations, the signaling overhead for reporting the history information is large, and the efficiency of the communication system is reduced. Here, RNA (RAN-based Notification Area) indicates a Notification region by RAN.

Based on this, the present application provides a communication method, the core idea of which is: by utilizing the capability of acquiring more comprehensive historical information of the terminal equipment, the terminal equipment performs statistical analysis according to the historical information of the terminal equipment to acquire the prediction information of the resident area and sends the prediction information of the resident area to the base station so as to realize that the base station acquires the prediction information of the resident area with higher accuracy, and then the base station can perform operations such as reasonable resource scheduling based on the acquired prediction information of the resident area.

In the application, the terminal equipment can obtain comprehensive historical information, and the accuracy of the prediction information of the resident area obtained by the terminal equipment according to the historical information of the terminal equipment is higher; in addition, the terminal equipment sends the resident area prediction information with higher accuracy to the base station, and compared with the mode that the terminal equipment reports the historical information in the prior art, the scheme of the application not only realizes that the base station obtains the resident prediction information with higher accuracy, but also greatly reduces the signaling overhead caused by reporting the historical information by the terminal equipment.

The communication method provided by the present application is described in detail below with reference to several specific embodiments.

Fig. 2 is a flowchart of a first embodiment of a communication method provided in the present application. As shown in fig. 2, the method of the present embodiment includes:

s201, the terminal device sends the prediction information of the resident area of the terminal device to the base station, wherein the prediction information of the resident area comprises: prediction information of the cell and/or TA in which the terminal device resides.

The resident area prediction information includes prediction information of a resident cell/tracking area corresponding to the terminal device. Specifically, the resident area prediction information includes the identity of the predicted resident cell and/or TA and the prediction information of each resident cell and/or TA. The identifier of the resident cell and/or TA is, for example, an identifier such as a name, an ID, and the like of the resident cell and/or TA; exemplarily, in the NR system, the identity of the Cell may be a Cell Global Identity (CGI), where the NR CGI is composed of a NR Cell ID and a Public Land Mobile Network (PLMN) ID; in an E-UTRA system, the identity of a cell may be a combination of an E-UTRA cell ID and a PLMN ID. The identification of the TA may be represented by a Tracking Area Identity (TAI) or a Tracking Area Code (TAC), where the TAI is composed of a PLMN ID and a TAC.

Where "resident" indicates that the terminal device is likely to camp on in the future, the resident cell and/or TA may be determined by one or more of a predicted probability determination of camping, a predicted length of camping, and a predicted connection state. Of course, the resident cell and/or TA may also be determined from other prediction data.

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

Illustratively, the time period for which the terminal device is camped in the resident cell and/or TA is, for example: n hours from the current time, wherein N is greater than 0; the length of time that the terminal device resides in the resident cell and/or TA is, for example, the time period of 9:00-18:00 on monday to friday; the probability that the terminal device resides in the resident cell and/or TA is, for example: 50 percent. Here, the prediction information of the resident cell and/or TA is only an example and not a limitation.

It should be noted that the prediction information of the resident cell and/or TA includes the time period in which the terminal device resides in the resident cell and/or TA, the length of time the terminal device resides in the resident cell and/or TA, and the probability of the terminal device residing in the resident cell and/or TA, which are prediction data obtained by the terminal device according to the history information of the terminal device.

It should be understood that if the resident cell and/or TA includes a plurality of cells and/or TAs, there may be a difference between the prediction information corresponding to each of the plurality of cells and/or TAs.

In the present application, the data format of the prediction information of the permanent area is not limited, and may be in the form of a data list, a text, or another format.

According to a possible implementation manner, the terminal device may obtain the information of the area where the terminal device resides through a preset correlation algorithm according to the information of the cell where the terminal device resides, the historical location information of the terminal device, the length of time of residence in the cell where the terminal device resides, the historical information of the time period of residence in the cell where the terminal device resides, and the like, the current signal quality, the current connection state, and the like. Alternatively, the history information may be history information of the terminal device within a preset time period, which may be, but is not limited to, 1 year, 1 quarter, 1 month, 1 week, and the like.

Specifically, the terminal device obtains, according to the history information of the terminal device, the current signal quality, the current connection state, and other information, prediction data corresponding to each resident cell and/or TA in the cells and/or TAs where the terminal device resides, where the prediction data may include: one or a combination of a probability of residence, a length of residence time, and a period of residence time; determining resident cells and/or TAs according to the corresponding prediction data of each resident cell and/or TA; and acquiring the resident area prediction information according to the resident cell and/or TA and the prediction data corresponding to the resident cell and/or TA.

The resident cell and/or TA is determined according to the resident probability and/or the resident time length corresponding to each resident cell and/or TA, and the method can be realized by the following steps:

in a possible implementation manner, the terminal device determines a resident cell and/or TA according to a resident probability corresponding to each resident cell and/or TA and a first preset threshold. For example, the resident cell and/or TA is a cell and/or TA in which the terminal device resides, and the probability of residing is greater than the first preset threshold.

In another possible implementation manner, the terminal device determines the resident cell and/or TA according to the resident time length 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 resides, and the length of the resident time is greater than a second preset threshold.

In another possible implementation manner, the terminal device determines the resident cell and/or TA together according to the residence probability and residence time length corresponding to each resident cell and/or TA. Illustratively, the resident cell and/or TA is a cell and/or TA where the terminal device resides, the probability of residence is greater than a first preset threshold, and the length of residence time is greater than a second preset threshold, the cell and/or TA.

In the foregoing manner, the first preset threshold may be configured by the network side, or may also be agreed by a protocol, or may also be determined by the terminal device itself, which is not limited in this embodiment of the present application. The second preset threshold may be configured by the network side, or may also be agreed by a protocol, or may also be determined by the terminal device itself, which is not limited in this embodiment of the present application.

Optionally, the terminal device obtains, according to the history information of the terminal device, the current signal quality, the current connection state, and other information, prediction data corresponding to each camped cell and/or TA of the terminal device in the camped cell and/or TA, where the prediction data may further include: the connection state, here, the connection state may be a connection state, an idle state, and a deactivation state.

The resident cell and/or TA may also be determined according to the connectivity status of each camped cell and/or TA. Specifically, the resident cell and/or TA may be a cell and/or TA in which the terminal device resides, and the connection state is a connected cell and/or TA.

Optionally, the resident cell and/or TA may also be related according to the scenario in which the terminal device is located. For example, when the resident cell and/or TA is a cell handover performed by the terminal device, the handover probability of the cell and/or TA meeting the preset condition may be obtained according to the prediction data, such as the probability of camping, of the resident cell and/or TA acquired by the terminal device. For example, the resident cell and/or TA is the SCG when the terminal device enters DC mode. That is, the residential area prediction information may include information of a target cell to which the terminal device is most likely to be handed over at the current cell or information of a serving cell list controlled by the secondary base station entering a dual link state.

In some cases, the SCG may also be referred to as a second cell group, a serving cell group controlled by the secondary base station, or other names. The secondary base station may also be referred to by other names such as secondary base station, etc.

Alternatively, the terminal device may report the prediction information of the residential area to the base station through SRB1, SRB2, SRB3, and the like. Illustratively, the terminal device may transmit the persistent area prediction Information to the base station through one or more of an RRC Setup Complete message (RRC Setup Complete), an RRC Reestablishment Complete message (RRC Resume Complete), an RRC Reconfiguration Complete message (RRC Reconfiguration Complete), an RRC connection Setup request message (RRC Reestablishment Complete), UE Assistance Information (UE Assistance Information), uplink Information transmission (UL Information Transfer), uplink Information transmission for dual link (UL Information Transfer MRDC), and a terminal Information Response (UE Information Response).

In one possible implementation, if the prediction information of the residential area includes multiple sets of prediction information of the residential area, the terminal device may report the multiple sets of prediction information of the residential area to the base station. The plurality of sets of the residential area prediction information may be the residential area prediction information corresponding to different time periods determined by the terminal device according to the history information.

In this embodiment, a terminal device sends, to a base station, information about a permanent area prediction of the terminal device, where the information about the permanent area prediction includes: prediction information of the resident cell and/or TA; accordingly, the base station receives the residential area prediction information transmitted by the terminal device. In the embodiment, the terminal equipment can obtain comprehensive historical information, and the accuracy of the resident area prediction information obtained by the terminal equipment according to the historical information of the terminal equipment is higher; in addition, the terminal equipment sends the resident area prediction information with higher accuracy to the base station, and compared with the mode that the terminal equipment reports the historical information in the prior art, the scheme of the application not only realizes that the base station obtains the resident area prediction information with higher accuracy, but also greatly reduces the signaling overhead caused by reporting the historical information by the terminal equipment.

Fig. 3 is a flowchart of a second communication method according to the present application. As shown in fig. 3, the method of the present embodiment includes:

s301, the terminal equipment determines whether the information reporting condition is met.

And if the terminal equipment determines that the information reporting condition is met, executing S302.

In a possible implementation manner, the information reporting condition is as follows: the terminal equipment is located in a resident cell and/or TA.

In another possible implementation manner, the information reporting condition is as follows: the terminal equipment is located in a resident cell and/or TA, and the terminal equipment is in a connected state.

In another possible implementation manner, the information reporting condition is as follows: the terminal equipment is located in a resident cell and/or a neighbor cell of the TA.

In another possible implementation manner, the information reporting condition is as follows: the terminal device is located in a resident cell and/or a neighboring cell of the TA, and the terminal device is in a connected state.

In the above possible implementation manners, the terminal device may 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 may determine whether the terminal device is located in the resident cell and/or the TA neighbor cell according to the location information of the resident cell and/or the TA neighbor cell and the location of the terminal device itself.

It should be noted that the information reporting conditions in the embodiment of the present application are not limited to the above, and the terminal device may set different information reporting conditions in different scenarios, so as to implement dynamic adjustment of the information reporting conditions, and improve flexibility of information reporting.

For example, in a working day of 7:00 to 9:00, the user may be on the way to work, and the mobility of the terminal device is strong, so the information reporting condition may be that the terminal device is located in a resident cell and/or a neighboring cell of the TA; in working days 9:00-18:00, the user is usually located at the working place, and the mobility of the terminal equipment is low, so the information reporting condition can be that the terminal equipment is located in a resident cell and/or TA.

S302, the terminal equipment sends the resident area prediction information of the terminal equipment to the base station.

In this embodiment, S302 is similar to S201 in the embodiment shown in fig. 2, and reference may be made to the detailed description in the embodiment shown in fig. 2, which is not repeated herein.

In the scheme, when the terminal equipment determines that the information reporting condition is met, the prediction information of the resident area of the terminal equipment is sent to the base station, so that the base station can obtain the prediction information of the resident area with higher accuracy, and the requirement of the base station is met; in addition, the scheme in the embodiment can also greatly reduce the signaling overhead of the terminal equipment reporting the prediction information of the resident area.

Fig. 4 is a flowchart of a third embodiment of a communication method provided in the present application. On the basis of the embodiment shown in fig. 2, after S201, the method shown in this embodiment may further include:

s401, the terminal device sends first indication information to the base station, wherein the first indication information is used for indicating that the resident area prediction information exists in the terminal device.

Correspondingly, the base station receives the first indication information sent by the terminal equipment.

Specifically, in this embodiment, after obtaining the prediction information of the residential area, the terminal device may indicate that the base station has the prediction information of the residential area to be reported.

For example, the terminal device may carry the first indication information in an RRC message to indicate that the base station terminal device has the reportable residential area prediction information.

Optionally, the first indication information may include, in addition to the information indicating that the prediction information of the resident area exists in the terminal device, time information and probability information, where the time information may be determined according to a length of time that the terminal device resides in the resident cell and/or TA and/or a time period that the terminal device resides in the resident cell and/or TA; the probability information referred to herein may be determined based on the probability that the terminal device is camped on the resident cell and/or TA. In the step, the base station can reasonably determine whether the terminal equipment needs to report the prediction information of the resident area according to the first indication information by uploading the prediction information of the resident area with the coarse granularity, so that the system efficiency is improved.

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

S403, the terminal device transmits the permanent area prediction information to the base station.

Step S403 in this embodiment is similar to step S201 in the embodiment shown in fig. 2, and reference may be made to the detailed description of the terminal device sending the prediction information of the permanent area to the base station in step S201, which is not described herein again.

In this embodiment, the terminal device may send the first indication information to the base station when the information reporting condition is satisfied, and reasonably report the prediction information of the residential area based on the second indication information sent by the base station.

Fig. 6 is a flowchart of a fifth embodiment of a communication method provided in the present application. In some scenarios, the terminal device reports the prediction information of the residential area, and because the terminal device has mobility, the terminal device may need to perform cell handover, or service base station handover, and the like.

As shown in fig. 6, the method of the present embodiment includes:

s501, the terminal device sends the prediction information of the resident area of the terminal device to the base station.

In this embodiment, the terminal device sends the prediction information of the permanent area of the terminal device to the base station, and the terminal device may directly send the prediction information of the permanent area of the base station in the manner of the embodiment shown in fig. 2 and 3, or send the prediction information of the permanent area to the base station when the terminal device determines that the information reporting condition is satisfied; alternatively, in the manner of the embodiment shown in fig. 5, when determining that the information reporting condition is satisfied, the terminal device first sends the first indication information to the base station, and after receiving the second indication information sent by the base station, sends the residential area prediction information to the base station.

For details, reference may be made to the detailed description in the embodiments shown in fig. 2, fig. 3 and fig. 5, which is not repeated herein.

S502, the base station sends the prediction information of the resident area to a target base station.

In a scenario that the terminal device performs cell handover, the target base station is a target base station when the terminal device performs cell handover. That is, the source base station transmits the residential area prediction information to the target base station. And then, the target base station can realize a corresponding switching strategy according to the prediction information of the resident area.

When the terminal device is in the DC mode, if the base station that receives the residential area prediction information sent by the terminal device in S501 is the primary base station in the DC mode, the target base station is the secondary base station in the DC mode; if the base station receiving the permanent area prediction information transmitted by the terminal device in S501 is the secondary base station in the DC mode, the target base station is the primary base station in the DC mode.

In one possible implementation, if the base station determines that the residential cell and/or the TA included in the residential area prediction information includes the target base station, the base station sends the residential area prediction information to the target base station.

In the embodiment, after receiving the prediction information of the residential area sent by the terminal equipment, the base station can send the prediction information of the residential area to the target base station based on the current state of the terminal equipment, so that the prediction information of the residential area with higher accuracy can be obtained between the associated base stations; and the target base station can realize a corresponding RRM strategy according to the prediction information of the resident area, thereby improving the system efficiency. In addition, the embodiment greatly reduces signaling overhead on the basis that the base station and the target base station acquire accurate prediction information of the resident area.
