Description

Cell switching method and device

Technical Field

The present application relates to the field of communications, and in particular, to a cell switching method and apparatus.

Background

In a mobile communication system, in order to improve the utilization rate of spectrum resources and the capacity of the whole system, the radio frequency power in the system needs to be limited within a certain range. In the moving process of User Equipment (UE), switching can be performed according to the signal strength of a cell to obtain a better service.

The existing cell switching method is as follows: the source base station indicates the UE to measure the signal quality value of the adjacent cell, and after the source base station obtains the signal quality value of the adjacent cell measured by the UE, if the signal quality value of the adjacent cell is larger than the configured switching threshold, the source base station selects the target cell to indicate the UE to be switched to the target cell.

Currently, if the UE moves in a cell with the same frame structure, the existing cell switching method may be adopted. If the UE moves in cells with different frame structures, the existing cell switching method cannot meet the requirements of a user moving scene. Such as: when a large downlink frame structure (such as a DDDSU frame structure) service cell user is switched to a large uplink frame structure (such as a DSUUU frame structure) target cell, the existing cell switching method can cause the UE to be switched to the target cell of the large uplink frame structure when the UE is in a higher downlink throughput, so that the downlink throughput of the UE is reduced rapidly, and the service quality of the user is greatly reduced. The rapid decrease in throughput may cause a decrease in user network speed, etc. In the DDDSU frame structure and DSUUU frame, D represents a full downlink timeslot, U represents a full uplink timeslot, and S represents a special timeslot, that is, represents an uplink and downlink mixed timeslot and a guard timeslot.

Therefore, how to avoid the rapid decrease of throughput when the UE switches between cells with different frame structures becomes a problem to be solved urgently when the UE switches between cells with different frame structures.

Disclosure of Invention

The embodiment of the application provides a cell switching method, which can avoid that the throughput of UE (user equipment) drops a pit sharply when cells with different frame structures are switched so as to improve the user experience.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

in a first aspect, a cell handover method is provided, where the cell handover method provided in this application includes: a source base station receives a measurement report sent by UE; the measurement report includes: frame structure information of a neighboring cell, signal quality value of the neighboring cell; the frame structure information is used for indicating the frame structure of the adjacent cell; the source base station judges the cell switching according to the measurement report and the frame structure information of the current cell accessed by the UE; if the adjacent cell with the maximum signal quality value meets the condition, the switching judgment is successful; the condition is used for indicating that the neighbor cell with the largest signal quality value meets the throughput rate of the UE; and if the switching judgment is successful, the source base station indicates the UE to be switched to the target cell, and the target cell is the adjacent cell with the maximum signal quality value.

That is to say, the measurement report obtained by the source base station from the UE includes the frame structure information of the neighboring cell and the signal quality value of the neighboring cell, and then after determining that the neighboring cell with the largest signal quality value satisfies the condition and the signal quality value is greater than or equal to the decision threshold corresponding to the condition, the UE is instructed to switch to the neighboring cell, where the condition is used to instruct the neighboring cell to satisfy the throughput rate of the UE. Therefore, the stability of the throughput in the cell switching process can be ensured, and the user experience is improved.

In one possible design, the conditions include: the frame structure of the neighboring cell with the largest signal quality value is the same as that of the current cell, the signal quality value is greater than or equal to a first decision threshold, and the first decision threshold is a preset threshold. That is, the frame structure of the neighboring cell with the largest signal quality value is the same as the frame structure of the current cell of the UE, and the signal quality value of the neighboring cell with the largest signal quality value is greater than or equal to the first decision threshold, then the handover decision is successful. Therefore, the adjacent cell which has the same frame structure with the current cell and has a large signal quality value is selected as the target cell, the stability of throughput in the cell switching process is ensured, and the user experience is improved.

In one possible design, the above conditions may include: the frame structure of the adjacent cell with the maximum signal quality value is different from that of the current cell, but the frame structure of the adjacent cell with the maximum signal quality value meets the service direction indicated by the current main service indication information of the UE, the signal quality value is greater than or equal to a third judgment threshold, and the third judgment threshold is smaller than the first judgment threshold; or the frame structure of the neighboring cell with the largest signal quality value is different from the frame structure of the current cell, and the frame structure of the neighboring cell with the largest signal quality value does not satisfy the service direction indicated by the current main service indication information of the UE, but the signal quality value is greater than or equal to a second decision threshold, and the second decision threshold is greater than the first decision threshold.

That is, the source base station acquires the current main service indication information of the UE, and then determines whether the frame structure of the neighboring cell with the largest signal quality value is the same as the frame structure of the current cell of the UE according to the measurement report, the current main service indication information, the frame structure information of the current cell, and the decision threshold, and if not, determines whether the frame structure of the neighboring cell with the largest signal quality value satisfies the service direction indicated by the current main service indication information of the UE, and if so, the signal quality value of the neighboring cell with the largest signal quality value is greater than or equal to the third decision threshold; or, if the signal quality value is not satisfied, and the signal quality value of the neighboring cell with the largest signal quality value is greater than or equal to the second decision threshold; the source base station instructs the UE to handover to the neighbor cell with the largest signal quality value.

Therefore, by configuring the corresponding judgment threshold when the frame structure of the selection frame and the frame structure of the current cell meet different relations, the adjacent cell with the signal quality value larger than the judgment threshold corresponding to the met conditions is selected for switching, the stability of throughput in the cell switching process is ensured, and the user experience is further improved.

In one possible design, the cell handover method provided in the present application may further include: a source base station acquires current main service indication information of UE; the current main service indication information of the UE is used for indicating the UE to mainly carry out uplink service or downlink service. Therefore, the source base station can acquire the service direction of the UE from the indication information of the UE, the complexity of acquiring the service direction of the UE by the source base station is reduced, and the system design is simplified.

In one possible design, the UE current primary traffic indication information may include: uplink traffic throughput and downlink traffic throughput. The cell switching method provided by the present application may further include: and determining the service direction indicated by the current main service indication information of the UE according to the uplink service throughput and the downlink service throughput of the UE. Wherein, if the uplink service throughput UThr and the downlink service throughput DThr satisfy the following relationship: UThr is more than or equal to x DThr, x is a preset numerical value more than 1, and the service direction is an uplink service; if not, the service direction is a downlink service.

That is, the service direction indicated by the current main service indication information of the UE is determined according to the uplink service throughput and the downlink service throughput of the UE, so that the target cell is selected according to the current main service indication information of the UE, the measurement report, the frame structure information of the current cell, and the decision threshold.

Therefore, the UE current service indication information can be accurately determined according to the uplink and downlink service throughput, and the situation that the UE is switched to the adjacent cell which does not meet the UE throughput rate due to the fact that the UE current service indication information is not accurate is reduced.

In one possible design, the frame structure of the neighbor cell includes a large uplink frame structure or a large downlink frame structure; the large uplink frame structure is a frame structure comprising an uplink time slot, a downlink time slot and a special time slot, wherein the uplink time slot occupation ratio is higher than the downlink time slot occupation ratio; the large downlink frame structure is a frame structure comprising an uplink time slot, a downlink time slot and a special time slot, wherein the proportion of the downlink time slot is higher than that of the uplink time slot.

The target cell is the adjacent cell with the maximum signal quality value, the target cell meets the condition, and the signal quality value of the target cell is greater than or equal to the judgment threshold corresponding to the condition; the condition is used to indicate that the neighbor cell having the largest signal quality value satisfies the throughput of the UE.

That is to say, the UE sends the frame structure information of the neighboring cell and the signal quality value of the neighboring cell, which are included in the measurement report, to the source base station, and the source base station instructs the UE to switch to the neighboring cell after determining that the neighboring cell with the largest signal quality value satisfies the condition and that the signal quality value of the neighboring cell is greater than or equal to the decision threshold corresponding to the condition, where the condition is used to instruct the neighboring cell to satisfy the throughput rate of the UE. Therefore, the stability of the throughput of the UE during cell switching can be ensured, and the user experience is improved.

Further, the access network device 110 and the access network device 120 referred to in this application may be: an evolved node B (eNB), a home base station, an Access Point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a Transmission Point (TP), or a Transmission and Reception Point (TRP).

For convenience of description, the UE is used for terminal equipment unification.

The embodiment of the application is mainly applicable to a communication scenario in which the terminal 130 performs cell switching. In the following description of the embodiments of the present application, the terminal 130 is handed over from the current cell to the target cell as an example. It should be understood that the current cell and the target cell may be cells under the same access network device, or may be cells under different access network devices.

The embodiment of the application provides a cell switching method, which is used for UE to perform cell switching. It should be noted that the cell handover process of each UE is the same, and the following embodiments of the present application only describe the cell handover process performed by interaction between one UE and a base station, and the others are not described in detail any more.

As shown in fig. 2, the cell handover method provided in the embodiment of the present application may include the following steps:

s201, the UE acquires the frame structure information and the signal quality value of the adjacent cell of the cell accessed by the UE currently.

Wherein the frame structure information is used for indicating the frame structure of the neighbor cell.

Optionally, the frame structure of the neighboring cell includes a large uplink frame structure or a large downlink frame structure. The large uplink frame structure is a frame structure comprising an uplink time slot, a downlink time slot and a special time slot, wherein the uplink time slot occupation ratio is higher than the downlink time slot occupation ratio, and the large downlink frame structure is a frame structure comprising the uplink time slot, the downlink time slot and the special time slot, wherein the downlink time slot occupation ratio is higher than the uplink time slot occupation ratio.

Further, the large uplink frame structure may be a frame structure in which the uplink timeslot proportion is higher than 50 percent; the large downlink frame structure may be a frame structure in which the downlink timeslot proportion is higher than 50 percent.

For example, if the frame structure is a DSUUU, where D represents a complete downlink timeslot, S represents a special timeslot including an uplink timeslot and a downlink timeslot, and U represents a complete uplink timeslot, the uplink timeslot of the DSUUU frame structure is more than 50 percent, and further, the DSUUU frame structure is a large uplink frame structure. Similarly, the DDDSU frame structure is a large downlink frame structure.

Alternatively, the signal quality value may be one or more of: reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and signal to interference plus noise ratio (SINR).

For example, the UE may perform measurement according to the measurement indication sent by the source base station, and obtain frame structure information of a neighboring cell of a cell to which the UE is currently accessed and a signal quality value of the neighboring cell according to the measurement result.

Wherein the measurement indication may be used to indicate which measurement attributes of the measurement object are measured by the UE. In this embodiment of the present application, the measurement object may be a neighboring cell of a cell to which the UE is currently accessed, and the identifier of the measurement object may be a Physical Cell Identifier (PCI) of the neighboring cell. The measurement attributes may include: the frame structure information of the measurement object, the signal quality value of the measurement object, and the like may include, for example, frame structure information of a neighboring cell, a signal quality value of a neighboring cell, and the like.

In a possible implementation manner, the measurement indication may include a measurement object identifier (i.e., a neighbor cell identifier), and a measurement attribute (including a frame structure and a signal quality value), and after receiving the measurement indication sent by the source base station, the UE measures the measurement object indicated by the measurement object identifier according to the measurement indication to obtain the measurement attribute.

Another possible implementation manner is that before the source base station sends the measurement instruction to the UE, the UE and the source base station determine the measurement object and the measurement attribute in advance by establishing a measurement protocol or by defining a communication protocol, that is, it is realized that both the measurement object and the measurement attribute are known, at this time, the measurement instruction sent by the source base station to the UE is only used for triggering the UE to perform measurement, for example, the measurement instruction includes information indicating the UE to perform measurement, and after receiving the measurement instruction, the UE measures the frame structure information and the signal quality value of the neighboring cell in response to the measurement instruction.

In another possible implementation manner, before the source base station sends the measurement instruction to the UE, the UE and the source base station determine the measurement attribute in advance by establishing a measurement protocol or defining a communication protocol, that is, it is realized that both sides of the measurement attribute are known, and the measurement instruction sent by the source base station to the UE may include: and after receiving the measurement instruction, the UE measures the neighboring cell indicated by the neighboring cell identifier included in the measurement instruction, and obtains frame structure information and a signal quality value of the measured neighboring cell to measure.

In this embodiment of the present application, the measurement indication may further include: reporting a measurement report condition, wherein the reporting of the measurement report condition can be a condition for reporting a measurement report after the UE completes measurement on the neighboring cell. And if the measurement report meets the condition of reporting the measurement report, the UE sends the measurement report to the source base station.

In this embodiment of the present application, the source base station may send the measurement instruction periodically, or when the signal quality of the cell to which the UE accesses is less than the threshold, the source base station sends the measurement instruction.

S202, the UE sends a measurement report to the source base station.

Wherein the measurement report includes: frame structure information of neighbor cells, signal quality values of neighbor cells.

In a possible design, in the case that the measurement indication in S201 includes a condition for reporting a measurement report, if the UE determines that the measurement report obtained by measuring the neighboring cell satisfies the condition for reporting the measurement report, the UE sends the measurement report to the source base station.

In another possible implementation manner, after the UE completes measurement, the UE automatically sends a measurement report to the source base station according to a measurement protocol or a communication protocol established between the UE and the source base station.

Optionally, the UE may further obtain current main service indication information of the UE and send the current main service indication information to the source base station, so that the source base station determines the service direction of the UE according to the current main service indication information of the UE.

The current main service indication information of the UE is used to indicate a service direction of the UE, where the service direction may include an uplink service or a downlink service. The service direction of the UE may be determined according to the uplink service throughput and the downlink service throughput of the UE. For example, if the uplink traffic throughput UThr and the downlink traffic throughput DThr satisfy the following relationship: if UThr is greater than or equal to x DThr, the service direction of the UE is an uplink service; and if not, the service direction of the UE is a downlink service. It should be noted that x is a preset value greater than 1, and can be set as needed, and the specific value of x is not limited in the embodiment of the present application.

In a possible implementation manner, the UE current primary service indication information may include: uplink traffic throughput and downlink traffic throughput of the UE. For example, after acquiring the uplink service throughput and the downlink service throughput of the UE, the UE directly sends the uplink service throughput and the downlink service throughput of the UE to the source base station as the current main service indication information of the UE, so that the source base station determines the service direction of the UE according to the uplink service throughput of the UE and the downlink service throughput of the UE.

In another possible implementation, the current main traffic indication information of the UE may include a traffic direction of the UE. For example, after acquiring the uplink service throughput and the downlink service throughput of the UE, the UE determines the service direction of the UE according to the uplink service throughput and the downlink service throughput of the UE, and then sends the service direction of the UE to the source base station as the current main service indication information of the UE, so that the source base station directly determines the service direction of the UE according to the content carried by the current main service indication information of the UE.

In a possible implementation manner, the current primary service indication information of the UE may be carried in a measurement report and sent to the source base station together, so as to save signaling overhead.

In a possible implementation manner, the UE current primary service indication information may be sent to the source base station separately.

S203, the source base station receives the measurement report sent by the UE.

It should be noted that the measurement report received by the source base station in S203 is the measurement report sent by the UE in S202, and details thereof are not described herein again.

And S204, the source base station judges the cell switching according to the measurement report and the frame structure information of the current cell accessed by the UE.

The source base station reads the configuration of the source base station, and obtains the frame structure information of the cell (current cell) to which the UE is currently accessed.

Specifically, if the cell handover decision in S204 is successful, then the source base station instructs the UE to handover to the target cell in S205, where the target cell is an adjacent cell with the largest signal quality value; if the switching judgment is unsuccessful, the cell switching process is ended.

In S204, the determining, by the source base station, cell handover according to the measurement report and the frame structure information of the current cell accessed by the UE may include: and the source base station selects the adjacent cell with the maximum signal quality from the adjacent cells, if the adjacent cell with the maximum signal quality meets the condition and the signal quality value of the adjacent cell is greater than or equal to the judgment threshold corresponding to the condition, the switching judgment is successful, the adjacent cell with the maximum signal quality is taken as the target cell, and otherwise, the cell switching judgment fails.

The above condition is used to indicate that the neighbor cell satisfies the throughput of the UE. The specific content of the condition can be configured according to actual requirements, and specifically, the following implementation manner can be referred to.

In a possible implementation manner, the condition may be configured that the frame structure is the same as that of the current cell, the signal quality value is greater than or equal to a first decision threshold, and the first decision threshold is a preset threshold, so as to strictly ensure throughput stability when the UE performs cell handover.

In another possible implementation manner, the condition may be configured that the frame structure is different from the frame structure of the current cell, the signal quality value is greater than or equal to the second decision threshold, and the neighboring cell with high signal quality is selected as the target (to be switched) cell as far as possible by tightening (expanding) the decision threshold as the second decision threshold (greater than the first decision threshold), so as to ensure the throughput after the UE is switched as far as possible.

The second decision threshold may be δ times the first decision threshold, and δ is a constant greater than 1.

In another possible implementation manner, the condition may be configured such that the frame structure of the neighboring cell with the largest signal quality is different from the frame structure of the current cell, but the frame structure of the neighboring cell with the largest signal quality satisfies the service direction of the UE, and the signal quality value is greater than or equal to the third decision threshold, and the decision threshold (the third decision threshold) in the condition may be smaller than the first decision threshold to relax the decision threshold, so as to ensure throughput stability of the UE during cell switching as much as possible in a scenario with different frame structures being compromised.

The third decision threshold can be the first decision threshold multiplied by gamma, and gamma is a constant between 0 and 1.

In another possible implementation manner, the condition may be configured that the frame structure of the neighboring cell with the largest signal quality is different from the frame structure of the current cell, the frame structure of the neighboring cell with the largest signal quality does not satisfy the service direction of the UE, the signal quality value is greater than or equal to the second decision threshold, and the neighboring cell with the high signal quality is selected as the target (to be switched) cell as far as possible by tightening (expanding) the decision threshold as the second decision threshold (greater than the first decision threshold), so as to ensure the throughput after the UE is switched as far as possible.

As can be seen from the above, the cell decision process in the embodiment of the present application may include: selecting an adjacent cell with the maximum signal quality value from the adjacent cells, if the frame structure of the adjacent cell with the maximum signal quality value is the same as that of the current cell, comparing the signal quality value of the adjacent cell with the maximum signal quality value with a first judgment threshold, if the signal quality value of the adjacent cell is greater than or equal to the first judgment threshold, the cell switching judgment is successful, otherwise, the cell switching judgment is failed;

if the frame structure of the neighboring cell with the largest signal quality value is different from the frame structure of the current cell, the frame structure is adjusted to be a first decision threshold (for example, adjusted to be a second decision threshold or a third decision threshold), the signal quality value of the neighboring cell with the largest signal quality value is compared with the adjusted decision threshold, if the signal quality value is greater than or equal to the adjusted decision threshold, the cell switching decision is successful, otherwise, the cell switching decision is failed.

Specifically, the decision process may be described with reference to S301 to S305 in fig. 3:

s301, the source base station judges whether the frame structure of the target cell is the same as that of the current cell.

If the frame structure of the target cell is the same as the frame structure of the current cell in S301, S302 is executed, otherwise, S303 is executed.

S302, the source base station judges whether the signal quality value of the target cell is larger than or equal to a first judgment threshold.

If the signal quality value of the target cell is judged to be greater than the first judgment threshold in the S302, the switching judgment is successful, otherwise, the switching judgment is unsuccessful.

S303, the source base station judges whether the frame structure of the target cell meets the service direction indicated by the current main service indication information of the UE.

The frame structure of the target cell is a large uplink frame structure, the current main service indication information of the UE indicates that the uplink service is mainly performed, and the frame structure of the target cell meets the service direction indicated by the current main service indication information of the UE. Or the frame structure of the target cell is a large downlink frame structure, the current main service indication information of the UE indicates that the downlink service is mainly performed, and the frame structure of the target cell satisfies the service direction indicated by the current main service indication information of the UE.

If it is determined in S303 that the frame structure of the target cell satisfies the service direction indicated by the current primary service indication information of the UE, S304 is executed, otherwise, S305 is executed.

S304, the source base station judges whether the signal quality value of the target cell is larger than or equal to a third judgment threshold.

If the signal quality value of the target cell is judged to be greater than or equal to the third judgment threshold in the S304, the switching judgment is successful; otherwise, the handover decision is unsuccessful.

S305, the source base station judges whether the signal quality value of the target cell is larger than or equal to a second judgment threshold.

If the signal quality value of the target cell is judged to be greater than or equal to the second judgment threshold in the step S305, the switching judgment is successful; otherwise, the handover decision is unsuccessful.

And the source base station performs S205 if the handover decision is successful, or ends the handover if the handover decision is unsuccessful.

S205, the source base station sends a switching instruction to the UE.

Wherein, the switching indication includes the mark of the target cell.

S206, the UE receives the switching indication sent by the source base station.

S207, the UE is switched to the target cell from the current cell.

Wherein the switching of the UE from the current cell to the target cell comprises: specifically, the method for switching the UE from the current cell to the target cell (cell to be switched) is not repeated herein.

According to the scheme provided by the application, a measurement report acquired by a source base station from UE comprises frame structure information of an adjacent cell and a signal quality value of the adjacent cell, and then the UE is instructed to be switched to the adjacent cell after the adjacent cell with the maximum signal quality value is determined to meet a condition and the signal quality value of the adjacent cell is greater than or equal to a judgment threshold corresponding to the condition, wherein the condition is used for instructing the adjacent cell to meet the throughput rate of the UE. Therefore, the stability of the throughput in the cell switching process can be ensured, and the user experience is improved.
