Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

It should be noted that, all actions of acquiring signals, information or data in the present application are performed under the condition of conforming to the corresponding data protection rule policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.

Fig. 1 is a flow chart illustrating a method of cell handover according to an example embodiment. As shown in fig. 1, the cell switching method is used in a terminal and includes the following steps.

In step 110, when the service scenario where the terminal is located is a target service scenario, the first RSRP value of the serving cell is adjusted according to the first RSRQ value of the serving cell, so as to obtain a second RSRP value.

Here, the target service scenario may refer to a preset scenario, and/or the moving speed of the terminal is less than or equal to a preset speed threshold, and/or the uplink and downlink data amount of the terminal is greater than a preset data amount threshold. The preset scene may include a subway scene, a tunnel scene, and the like. Taking a subway scene as an example, in the subway scene, if the terminal is in a moving state, more interference is caused to the terminal by a complex network environment. At this time, the RSRQ becomes an important factor affecting the user data experience, and especially when the RSRQ of the terminal is smaller than-15 dB in the cell border area, the data is cut off, and even the data service cannot be used.

The first RSRQ value refers to a measurement result obtained by the terminal measuring the RSRQ of the serving cell. The first RSRQ value may determine an interfered strength to the terminal, the greater the interfered strength indicating that the current data traffic of the terminal is more affected. The first RSRP (REFERENCE SIGNAL RECEIVING Power, reference signal received Power) value refers to a measurement result obtained by the terminal measuring the RSRP of the serving cell. In the embodiment of the present disclosure, the serving cell refers to a cell to which the terminal accesses.

It should be understood that in the real network handover measurement event configuration, the measurement judgment is determined by a parameter of trigger quality (event trigger Quantity), and is generally configured as RSRP. Although report quality signaling may be configured to send both RSRP and RSRQ measurements to the base station, the base station determines whether to switch serving cells based on the RSRQ measurements. Wherein, report quality signaling is used to configure the physical Quantity to be reported. Thus, the first RSRP value of the serving cell may be adjusted according to the first RSRQ value of the serving cell to obtain the second RSRP value.

It is worth noting that the adjustment amplitude of the first RSRP value may be different for different first RSRQ values. The purpose of adjusting the first RSRP value is to enable the terminal to smoothly switch to other cells when the signal of the serving cell to which the terminal is currently connected is poor.

In step 120, the second RSRP value is sent to the base station, so that the base station allocates a new serving cell to the terminal according to the second RSRP value.

Here, the terminal sends a second RSRP value to the base station, so that the base station determines whether a cell handover condition is reached according to the second RSRP value, and if the cell handover condition is reached, the base station switches a new serving cell for the terminal.

It should be understood that cell handover refers to the transfer of a communication link between a terminal and a serving cell to a target cell by a communication system in order to ensure continuity of communication and quality of service of the terminal, when the terminal using network services moves from one cell to another, or due to load adjustment of radio transmission traffic, or active operation maintenance, or equipment failure, etc.

Therefore, when the service scene where the terminal is located is the target service scene, the first RSRP value of the service cell is adjusted according to the first RSRQ value of the service cell to obtain a second RSRP value, and the second RSRP value is sent to the base station, so that the base station distributes a new service cell for the terminal according to the second RSRP value. Based on the method, the first RSRP value can be adjusted according to the interference intensity of the terminal in the target service scene, so that the terminal can be switched to a cell with better signal in advance, and the data service experience of the user in the target service scene is improved.

In some implementations, in step 110, adjusting the first RSRP value of the serving cell according to the first RSRQ value of the serving cell to obtain the second RSRP value includes:

Here, a neighboring cell may be referred to as a neighboring cell, and a serving cell may have a handover relationship with one or more neighboring cells. The second RSRQ value refers to a measurement result obtained by the terminal measuring the RSRQ of the neighboring cell.

The difference value between the second RSRQ value of the adjacent cell and the first RSRQ value of the serving cell is greater than or equal to a preset threshold value, which indicates that the signal of the adjacent cell is better than the signal of the serving cell. At this time, the terminal may switch to the neighboring cell with better signal, so the terminal may adjust the first RSRP value of the serving cell according to the first RSRQ value of the serving cell, and obtain the second RSRP value, so that the terminal may switch to the neighboring cell with better signal.

The preset threshold may be 3dB, for example. For example, when the difference between the second RSRQ value and the first RSRQ value is 3dB or more, the first RSRP value of the serving cell is adjusted according to the first RSRQ value, and the second RSRP value is obtained.

It should be noted that, the preset threshold value being 3dB is one embodiment provided in the present disclosure, and in the practical application process, the preset threshold value may also be another value. But no matter how the preset threshold value is taken, the first RSRP value is triggered and adjusted under the condition that the signal of the adjacent cell is better than the signal of the service cell.

Therefore, under the condition that the difference value between the second RSRQ value of the adjacent cell and the first RSRQ value of the serving cell is larger than or equal to a preset threshold value, the first RSRP value is triggered and adjusted, so that the terminal can be switched to the adjacent cell with better signal, the data service experience of the user is improved, and the first RSRP value is not frequently triggered and adjusted.

Fig. 2 is a detailed flow chart of step 110 shown in fig. 1. As shown in fig. 2, in some implementations, in step 110, adjusting the first RSRP value of the serving cell according to the first RSRQ value of the serving cell to obtain the second RSRP value may include the following steps.

In step 111, a penalty factor is determined from the first RSRQ value of the serving cell, wherein the magnitude of the penalty factor is positively correlated with the magnitude of the first RSRQ value of the serving cell.

Here, the penalty factor is determined based on the magnitude of the first RSRQ value. The penalty factor is used to penalty the first RSRP value to obtain a second RSRP value.

Illustratively, the magnitude of the penalty factor is positively correlated with the magnitude of the first RSRQ value of the serving cell.

For example, when the first RSRQ value is less than-15 dB, the corresponding first RSRP value may be-110 dBm and the penalty factor may be (first RSRQ value +15) dBm. When the first RSRQ value is greater than or equal to-15 dB and less than-13 dB, the corresponding first RSRP value may be-106 dBm, and the penalty factor may be (first RSRQ value+13) ×2dbm. When the first RSRQ value is greater than or equal to-13 dB and less than-11 dB, the corresponding first RSRP value may be-98 dBm, and the penalty factor may be (first RSRQ value +11) ×4dbm.

It should be appreciated that different sizes of the first RSRQ values actually reflect different distances of the terminal from the serving cell. The magnitude of the penalty factor varies for different distances. Illustratively, the closer to the edge coverage area of the serving cell, the smaller the penalty factor, and the closer to the center location of the serving cell, the greater the penalty factor. For example, when the first RSRQ value is less than-15 dB, the first RSRP value may be-110 dBm, which indicates that the terminal is located in the edge coverage area of the serving cell. When the first RSRQ value is greater than or equal to-13 dB and less than-11 dB, the corresponding first RSRP value may be-98 dBm, which indicates that the terminal is located in the center of the serving cell.

In step 112, the second RSRP value is obtained from the penalty factor and the first RSRP value of the serving cell.

Here, after determining the penalty factor, the first RSRP value may be adjusted according to the penalty factor to obtain the second RSRP value.

For example, when the first RSRQ value is less than-15 dB, the corresponding first RSRP value may be-110 dBm, the penalty factor may be (first RSRQ value +15) dBm, and the second RSRP value= -110+ (first RSRQ value +15) dBm.

When the first RSRQ value is greater than or equal to-15 dB and less than-13 dB, the corresponding first RSRP value may be-106 dBm, the penalty factor may be (first RSRQ value+13) ×2dbm, and the second RSRP value= -106+ (first RSRQ value+13) ×2dbm.

When the first RSRQ value is greater than or equal to-13 dB and less than-11 dB, the corresponding first RSRP value may be-98 dBm, the penalty factor may be (first RSRQ value +11) ×4dbm, and the second RSRP value= -98+ (first RSRQ value +11) ×4dbm.

It should be noted that the first RSRP value is-98 dBm, which indicates that the terminal is located at the center of the serving cell, where the first RSRQ value is greater than or equal to-13 dB and less than-11 dB, and corresponds to a scenario where the first RSRQ value is better but the first RSRQ value is worse. Therefore, a larger penalty is required for the first RSRP value to bring the second RSRP value to the threshold value for cell handover.

Therefore, the first RSRP value is adjusted by the penalty factor positively correlated with the magnitude of the first RSRQ value of the serving cell, so that the terminal can adjust the RSRP measurement result of the serving cell according to different interference intensities, and the serving cell can more easily reach the cell switching threshold.

In some implementations that may be implemented, in step 120, sending the second RSRP value to the base station includes:

Here, after the second RSRP value is obtained, if the first RSRP value is greater than the second RSRP value, the second RSRP value is used as an RSRP measurement result of the terminal for the serving cell, and the second RSRP value is transmitted to the base station. If the first RSRP value is less than or equal to the second RSRP value, the first RSRP value may be directly sent to the base station, or the RSRP measurement result may not be uploaded.

It should be noted that the first RSRP value is greater than the second RSRP value, which indicates that the second RSRP value more easily reaches the threshold value of cell handover.

Therefore, under the condition that the first RSRP value is larger than the second RSRP value, the second RSRP value is sent to the base station, so that the terminal can be smoothly switched to a service cell with better signal, and the data service experience of the user in the target service scene is improved.

In some possible implementations, when the terminal is located in a preset scene, the moving speed of the terminal is less than or equal to a preset speed threshold, and the uplink and downlink data amount of the terminal is greater than a preset data amount threshold, determining that the service scene in which the terminal is located is the target service scene.

The terminal may determine whether the terminal is located in the preset scene, further determine whether the moving speed of the terminal is greater than a preset speed threshold when the terminal is determined to be located in the preset scene, and determine whether the uplink and downlink data amounts of the terminal are greater than the preset data amount threshold when the moving speed of the terminal is greater than the preset speed threshold, and determine that the terminal is located in the target service scene when the moving speed of the terminal is greater than the preset data amount threshold.

The preset speed threshold value can be 80km/h, and the value of the preset speed threshold value can be set according to actual conditions. When the moving speed of the terminal is greater than the preset speed threshold, it means that the terminal moves at a higher speed, and if the terminal is located in the edge coverage area of the cell at the higher moving speed, the terminal is easy to lose synchronization, so that the first RSRP value can be adjusted at this time. And if the uplink and downlink data quantity of the terminal is larger than the preset data quantity threshold value, which indicates that the current data service requirement of the user is higher, the first RSRP value can be adjusted. If the uplink and downlink data amount of the terminal is smaller than or equal to the preset data amount threshold, the first RSRP value may not be adjusted.

It should be noted that, in the preset scenario, if the moving speed of the terminal is less than or equal to the preset speed threshold and the uplink and downlink data amount of the terminal is greater than the preset data amount threshold, it indicates that the current network environment where the terminal is located is extremely complex. At this time, the interference degree of the terminal can be determined according to the first RSRQ value, and the larger the interference degree is, the larger the influence on the current data service scene of the terminal is.

Therefore, when the terminal is located in a preset scene, the moving speed of the terminal is smaller than or equal to a preset speed threshold value, and the uplink and downlink data quantity of the terminal is larger than a preset data quantity threshold value, the service scene in which the terminal is located is determined to be the target service scene, so that the terminal can be separated from a service cell with poor RSRQ by adjusting a first RSRP value in a complex network environment, and the terminal is switched to an adjacent cell matched with the target service scene.

In some implementations, the preset scene includes a subway scene, and if the location information of the terminal characterizes that the terminal is located on a subway line or an application related to the subway of the terminal triggers a target operation, the terminal is determined to be located in the subway scene.

Here, in the case that the preset scene includes a subway scene, the terminal may determine whether the service scene in which the terminal is located is the subway scene according to the position information of the terminal, and determine that the terminal is located on the subway scene when the position information of the terminal indicates that the terminal is located on the subway line. For example, when the terminal is located at a subway station or on a subway line, it is determined that the terminal is located in a subway scene.

And under the condition that the preset scene comprises a subway scene, if the terminal detects that an application program related to the subway triggers a target operation, determining that the terminal is positioned in the subway scene. For example, if the terminal detects that the "subway-on-a-card" application triggers NFC (NEAR FIELD Communication) broadcast, it is determined that the terminal is located in a subway scene. Or when the terminal detects that the two-dimensional code of the incoming station of the subway one-card application program is triggered, determining that the terminal is located in a subway scene.

It should be appreciated that application triggering target operations associated with a subway actually the end user experiences subway riding behavior, which may be triggered by any application, and are not illustrated in the embodiments of the present disclosure.

Therefore, whether the terminal is in a subway scene can be accurately determined through the position information and the triggering target operation of the application program.

In some possible embodiments, in a case where the location information of the terminal characterizes that the terminal is located on a subway line or an application related to a subway of the terminal triggers a target operation, determining altitude change information of the terminal within a preset time range, and determining that the terminal is located in the subway scene when the altitude change information is greater than a preset altitude threshold.

Here, under the condition that the position information of the terminal characterizes that the terminal is located on a subway line or an application program related to a subway of the terminal triggers a target operation, the terminal can detect height change information of the terminal in a preset time range through a height sensor, and if the height change information is larger than a preset height threshold value, the terminal is determined to be located in a subway scene.

It should be noted that the preset time range may be set according to actual situations. The preset time range actually represents a period of time after a user of the terminal enters the subway, and whether the user takes the subway or not can be accurately judged through the height change information in the preset time range.
