Technical Field

Along with increasingly obvious differentiation of application demands of consumers, mobile terminals are accelerated in realizing two polarization trends of cost difference (the cost of the terminals is in a certain connection with the demodulation capability of the baseband to a certain extent), and the application scenes of the mobile terminals are also more and more complex.
The current reality is: these cost differentiated terminals coexist with conventional terminals at any possible location in the same network, and a cell network is typically configured with a set of mobility value management parameters due to the enormous cost of network management optimization to the operator.
However, configuring a set of mobility value management parameters for the same cell may cause the set of network parameters to be different for different cost terminals, while the set of network parameters may cause the high performance terminals to be mismatched even at partial geographic locations. The method is characterized in that the mobile value of some low-cost terminals in the existing network is seriously influenced, or the mobile value of some special geographic environment positions of high-performance terminals in the network is seriously influenced, and finally, the user experience is directly reflected to have extremely large sliding down compared with the conventional terminals or the network reasonable coverage scene. A common set of parameters of the network may also cause that it is difficult for a cell to completely match different application requirements of different terminals. The method is characterized in that the bottom layer of the base band is as follows: (1) When the network measurement and switching trigger parameter conditions exceed the terminal resolution capability, and when the terminal measurement event meets the network configuration (cell bias or evaluation timer) switching condition reporting, part of terminal measurement reports can not be normally sent or the switching reconfiguration command issued by the network side can not be normally received; (2) If a plurality of cells are covered simultaneously in one environment, the terminal is difficult to autonomously select a network which is the best match with the service requirement to reside, so that the terminal works in a non-optimal state, and a certain experience fall is brought to a user relative to an ideal state.

Detailed Description
As described in the background, configuring a set of mobility value management parameters for the same cell may cause the set of network parameters to be different for different cost terminals, while a set of network parameters may cause even high performance terminals to be mismatched under part of the geographical location of the parameters. The method is characterized in that the mobile value of some low-cost terminals in the existing network is seriously influenced, or the mobile value of some special geographic environment positions of high-performance terminals in the network is seriously influenced, and finally, the user experience is directly reflected to have extremely large sliding down compared with the conventional terminals or the network reasonable coverage scene. A common set of parameters of the network may also cause that it is difficult for a cell to completely match different application requirements of different terminals.

In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Fig. 1 is a flowchart of a measurement reporting method according to an embodiment of the present invention.
The measurement reporting method of the embodiment of the invention can be used for terminal equipment such as mobile phones, computers, tablet computers and the like at the terminal side, namely, the terminal executes each step of the measurement reporting method.
Specifically, the measurement reporting method may include the following steps:
step S101: receiving measurement configuration information issued by a network side, wherein the measurement configuration information comprises a switching event and cell information to be measured;
step S102: acquiring a serving cell signal measurement value and a neighbor cell signal measurement value;
step S103: acquiring a movement value of a serving cell and a movement value of a neighbor cell, wherein the movement value of the serving cell represents the variation of the signal quality of the serving cell in a preset time period, and the movement value of the neighbor cell represents the variation of the signal quality of the neighbor cell in the preset time period;
step S104: when at least one of the movement value of the serving cell and the movement value of the neighbor cell reaches a preset threshold, correcting the neighbor cell signal measurement value by utilizing the difference value between the neighbor cell signal measurement value and the serving cell signal measurement value according to the signal quality of the serving cell;
step S105: judging whether the corrected measured value of the neighbor cell signal meets the switching event or not, and reporting a measurement report when the corrected measured value of the neighbor cell signal meets the switching event.
It should be noted that the serial numbers of the steps in the present embodiment do not represent a limitation on the execution sequence of the steps.
The serving cell signal measurement and neighbor cell signal measurement referred to in the embodiments of the present invention may refer to reference signal received power (Reference Signal Receiving Power, RSRP), or any other applicable technical index capable of characterizing signal quality, such as reference signal received quality (Reference Signal Receiving Quality, RSRQ), which is not limited in this embodiment of the present invention.
The network issues corresponding measurement parameters, such as a handover event and cell information to be measured, such as a cell identifier, to the terminal through the measurement configuration information. The measurement configuration information may also include cell list, reporting mode, measurement identity, event parameters, etc.
Specifically, a measurement configuration (measconfiguration) cell carried by a radio resource control (Radio Resource Control, RRC) signaling connection reconfiguration (connection reconfiguration) message by the base station (eNB) may notify a User Equipment (UE) of the measurement configuration message, i.e. issue measurement control. The UE will Measure the current serving cell and determine whether measurement of the neighbor cell needs to be performed according to the s-Measure cell in the rrcconnectionreconfiguration message. The UE may make the following types of measurements: co-frequency measurement: measuring on a downlink carrier frequency of a serving cell, including: RSRP, RSRQ, path loss (Pthloss), etc.; and (3) different frequency measurement: measurements are made on a different downlink carrier frequency than the serving cell, including RSRP, RSRQ, pthloss, etc.
Specifically, the switching event may be an A3/A4/A5 event. Wherein, the A3 event refers to that the signal quality of the adjacent cell is higher than the signal quality of the service cell by a threshold, and the event is used for the coverage-based switching between the intra-frequency and inter-frequency; a4 event means that the signal quality of the adjacent cell is higher than an absolute threshold, and the event is used for switching based on load and can be used for load balancing; the A5 event refers to that the Serving cell signal quality is below an absolute threshold1 (Serving < threshold 1) and the neighbor cell signal quality is above an absolute threshold2 (Serving > threshold 2), which is used for intra/inter-frequency coverage-based handover.
In the implementation of step S101, the terminal may receive measurement configuration information sent by the network side, and learn the handover event and the cell information to be measured.
After the terminal performs measurement according to the configuration of the network side, the terminal can determine the signal measurement value of each cell. In the implementation of step S102, the terminal may acquire the serving cell signal measurement value and the neighbor cell signal measurement value, and the number of neighbor cells may be one or more.
If the number of neighboring cells is plural, steps S103 to S104 are performed for each neighboring cell, so that the neighboring cell measurement value of each neighboring cell is corrected separately.
In the implementation of step S103, the terminal may acquire the movement value of the serving cell and the movement value of the neighboring cell. The movement value of a cell indicates the amount of change in signal quality of the cell within a preset time period, and may indicate the mobility of a terminal in the cell. The higher movement value of the cell indicates that the mobility of the terminal in the cell is higher, and the surrounding environment of the cell is changed substantially; otherwise, it means that the surrounding environment of the cell is not substantially changed.
Specifically, the terminal may retrieve the movement value of the serving cell and the movement value of the neighboring cell from a preset storage space according to the identifiers of the serving cell and the neighboring cell, where the movement value of each cell may be calculated in advance by the terminal and stored in the preset storage space.
In the implementation of step S104, when at least one of the movement value of the serving cell and the movement value of the neighboring cell reaches a preset threshold, it indicates that the surrounding environment of at least one of the serving cell and the neighboring cell is substantially changed, and an adjustment of the speed of cell handover, such as acceleration of cell handover or deceleration of cell handover, is required. The specific implementation mode for adjusting the cell switching speed is to correct the signal measurement value of the adjacent cell by utilizing the difference value between the signal measurement value of the adjacent cell and the signal measurement value of the service cell according to the signal quality of the service cell.
Specifically, when the signal quality of the neighbor cell is better than that of the serving cell, the difference between the signal measurement value of the neighbor cell and the signal measurement value of the serving cell is positive, and the signal measurement value of the neighbor cell is corrected by using the difference, so that the signal measurement value of the neighbor cell can be increased, that is, the corrected signal measurement value of the neighbor cell is larger than the signal measurement value of the neighbor cell before correction, so that the cell switching is accelerated. Otherwise, when the signal quality of the adjacent cell is worse than that of the serving cell, the difference is negative, and the signal measurement value of the adjacent cell can be reduced by correcting the signal measurement value of the adjacent cell by using the difference, namely, the corrected signal measurement value of the adjacent cell is smaller than the signal measurement value of the adjacent cell before correction, so that the speed-down cell switching is realized.
In a particular embodiment, the signal quality of the serving cell may be expressed in terms of a signal to interference plus noise ratio (Signal to Interference plus Noise Ratio).
In the implementation of step S105, the terminal determines whether to report the measurement report according to the corrected neighbor cell signal measurement value and the handover event issued by the network side.
Specifically, the reporting of the measurement report triggering condition is that after the UE completes measurement, the UE evaluates the reporting condition according to the measurement report configuration, and when the set condition is satisfied, the UE fills the measurement result into a MeasurementReport message and sends the measurement result to the eNB. The measurement report triggering mode is divided into periodicity and event triggering. The report content may include: the measurement ID, the measurement results of the serving cell (measurement values of RSRP and RSRQ), the measurement results of the neighbor cell (optional).
According to the embodiment of the invention, whether the surrounding environment of the service cell and/or the neighboring cell is changed substantially can be judged through the movement value of the service cell and the movement value of the neighboring cell, and when the surrounding environment of the service cell and/or the neighboring cell is changed substantially and the signal quality of the service cell possibly affects the disconnection of a terminal, namely, at least one of the movement value of the service cell and the movement value of the neighboring cell reaches a preset threshold, the signal measurement value of the neighboring cell is corrected according to the signal quality of the service cell, so that the cell switching speed is accelerated, the terminal can be switched to the cell with better signal quality more quickly, and the call experience of a user is improved. In addition, the embodiment of the invention corrects the signal measurement value of the adjacent cell by using the difference value between the signal measurement value of the adjacent cell and the signal measurement value of the service cell, and the difference value is negative under the condition that the signal quality of the adjacent cell is poor relative to the signal quality of the service cell, so that the service cell is prevented from being switched to the adjacent cell with poor signal quality under the condition that the signal quality is better.
From the aspect of terminal application requirements, the mobile terminal can be generally divided into two application requirement modes, one is that the transmission rate is extremely pursued, the transmission rate in unit time is expected to be as high as possible, and excessive requirements are not made on the transmission quality at all times, such as a real-time monitoring system cloud transmission module, which is hereinafter referred to as rate priority terminal application scene; one is the extremely high requirement for transmission quality, and this type of terminal has a high requirement for transmission quality on the basis of a certain guarantee of transmission rate, such as a voice communication module, which will be referred to as a signal transmission quality priority application scenario hereinafter.
In one non-limiting embodiment, step S104 shown in FIG. 1 may include the steps of: if the signal quality of the serving cell is greater than a first threshold, a first product of the difference and a first weight is calculated, and a sum of the neighbor cell signal measurement and the first product is calculated to serve as the corrected neighbor cell signal measurement.
In this embodiment, a signal quality of the serving cell being greater than the first threshold indicates that the decoding performance of the terminal in the communication range of the serving cell is better, the probability of dropped call for performing call is lower, and when the measured value of the signal of the neighboring cell is corrected at this time, the amplitude of correction or not can be smaller, that is, the value of the first weight can be set to be smaller, for example, 0.
In one non-limiting embodiment, step S104 shown in FIG. 1 may include the steps of: if the signal quality of the serving cell is greater than a second threshold, calculating a second product of the difference and a second weight, and calculating a sum of the neighbor cell signal measurement and the second product as the modified neighbor cell signal measurement, the second threshold being less than the first threshold, the second weight being greater than the first weight.
Different from the foregoing embodiments, the signal quality of the serving cell in the embodiments of the present invention is greater than the second threshold, and the second threshold is smaller than the first threshold, which indicates that the signal quality of the serving cell may cause the terminal to drop, and it is necessary to accelerate cell handover. When the measured value of the neighbor cell signal is corrected, the correction amplitude can be increased, that is, the value of the second weight can be set to be larger, if the second weight is larger than the first weight.
In one non-limiting embodiment, step S104 shown in FIG. 1 may include the steps of: if the signal quality of the serving cell is less than the second threshold, a third product of the difference and a third weight is calculated, and a sum of the neighbor cell signal measurement and the third product is calculated as the modified neighbor cell signal measurement, wherein the third weight is greater than the second weight.
Unlike the foregoing embodiments, the signal quality of the serving cell in the embodiments of the present invention is smaller than the second threshold, which indicates that the signal quality of the serving cell is already poor and that cell handover needs to be performed more quickly, where when the signal measurement value of the neighboring cell is corrected, the magnitude of the correction may be further increased, that is, the third weight may be set to be greater than the second weight.
The application requirement of the terminal in the above embodiment is that the signal transmission quality is preferential, and the signal transmission quality depends on the signal quality SINR of the cell, so the above embodiment sets the first threshold and the second threshold, and meets the requirements of different terminals on the signal transmission quality.
In one non-limiting embodiment, step S104 shown in FIG. 1 may include the steps of: and if the signal quality of the serving cell is greater than a second threshold, calculating a fourth product of the difference and a fourth weight, and calculating the sum of the measured value of the neighbor cell signal and the fourth product and a rate parameter to serve as the corrected measured value of the neighbor cell signal, wherein the rate parameter is calculated according to the measured bandwidth of the neighbor cell and the number of downlink samples for use in unit time of the neighbor cell.
Unlike the foregoing embodiment, where the application requirement of the terminal is signal transmission rate priority, in this embodiment, the signal transmission rate is related to the signal quality SINR of the cell and the number of downlink resources available for use by the cell, so when correcting the measured value of the signal in the neighboring cell, the embodiment of the present invention adds a rate parameter, where the rate parameter is calculated according to the measured bandwidth of the neighboring cell and the number of downlink samples available for use in unit time by the neighboring cell.
In specific implementation, the measurement bandwidth of the cell can be obtained from reconfiguration information configured by the network side for the terminal; the number of downlink samples for use by a cell per unit time may be configured to be 2 if the cell is in a time division duplex (Time Division Duplex, TDD) mode, and 10 if the cell is in a frequency division duplex (Frequency Division Duplex, FDD) mode.
The speed parameter in the embodiment of the invention can represent the requirement of the terminal on the transmission rate, and different parameter indexes are constructed by using various factors related to the application scene based on different terminal application scenes so as to weight the measured value of the neighbor cell signal for evaluating the switching event to influence the response of the target switching event, so that the switching target cell is matched with the requirement degree of the terminal application scene.
Further, the rate parameter is calculated by the following formula:
integrofford 1 = SinrOffset x Factor4+10 x lg (MeasPRB/100 x DlSubFrame) x Factor5 wherein integrofford 1 represents the rate parameter, sinrOffset represents the difference, factor4 represents the fourth weight, factor5 represents a fifth weight, measPRB represents a measurement bandwidth of the neighbor cell, dlSubFrame represents a number of downlink samples for use by the neighbor cell per unit time.
In one non-limiting embodiment, step S102 shown in FIG. 1 may be preceded by the steps of: acquiring a plurality of signal measurement value pairs of each cell in a first preset time period before the current moment, wherein each signal measurement value pair comprises a maximum signal measurement value and a minimum signal measurement value; and selecting the maximum signal measured value and the minimum signal measured value of all signal measured value pairs of each cell in the first preset time period, and calculating a difference value to be used as a movement value of each cell.
It should be noted that, the duration of the first preset time period may be set based on the terminal application scenario, and a value matched with the network may be trained in actual use, for example, 30s, which is not limited in the embodiment of the present invention.
In this embodiment, the terminal may count the signal strength index RSRP of each cell in a time period (i.e., the first time period) with the length of ObserveTimer1 in the past of the time period of each cell from the judgment time, and then obtain the maximum RSRP and the minimum RSRP (i.e., the maximum signal measurement value and the minimum signal measurement value) of each cell in the time period, which are respectively recorded as MaxRSRP, minRSRP.
And when calculating the movement value of the cell, counting the maximum signal measurement value and the minimum signal measurement value in all the maximum signal measurement values and the minimum signal measurement values in the time period of the ObserveTimer1 as the maximum signal measurement value and the minimum signal measurement value in the statistical analysis time period of the ObserveTimer 1. The movement value of the cell is the difference between the maximum and minimum values.
Further, the signal measurement value pair includes a maximum signal measurement value and a minimum signal measurement value within a second preset time period, and the duration of the second preset time period is smaller than the duration of the first preset time period.
Because the number of the measured cells of the terminal is large, and meanwhile, the measured value samples corresponding to each cell are also large in the observation time period ObserveTimer1, if each measured value corresponding to each cell is stored and is evaluated after the observation time period arrives, a large RSRP storage space is required, so that a sliding window processing mode can be adopted for saving the storage space, namely, each cell only has a RSRP value in a smaller time period ObserveTimer2 (namely, a second preset time period), and then the corresponding maximum and minimum RSRP value is taken as the maximum and minimum RSRP values in the window time period after the time of the time period reaches, and is stored. And then the terminal counts the maximum value and the minimum value in the maximum and minimum measured values corresponding to all the time periods of the ObserveTimer1/ObserveTimer2 in the time period of the ObserveTimer1, and the maximum and minimum measured values are used as the maximum signal measured value and the minimum signal measured value in the statistical analysis time period of the ObserveTimer 1.
