Technical Field

Along with increasingly obvious differentiation of application requirements of consumers, the two polarization trends of realizing cost difference (the cost of the terminal is in certain relation with the baseband demodulation capacity) of the mobile terminal are accelerated, and the application scene of the mobile terminal is more and more complex.
The current reality is that: these cost-differentiated terminals coexist in any possible location of the same network as conventional terminals, and because of the huge cost of network management optimization, a set of mobility value management parameters is usually configured for a cell network for an operator.
However, configuring a set of mobility management parameters in the same cell may cause the matching of the set of network parameters to terminals with different costs to be different, and a set of network parameters may cause the parameters to be mismatched even if the high-performance terminal is located in a part of the geographical location. The mobile value of some low-cost terminals in the existing network is seriously influenced, or the mobile value of high-performance terminals in some special geographical environment positions in the network is seriously influenced, and finally, the user experience is directly greatly reduced compared with that of the conventional terminals or the reasonable coverage scene of the network. A common set of parameters of the network may also make it difficult for a cell to completely match different application requirements of different terminals. The base band bottom layer is embodied as follows: (1) the conditions of network measurement and switching triggering parameters exceed the terminal analysis capability, and when a terminal measurement event meets the requirement of reporting a network configuration (cell offset or evaluation timer) switching condition, part of terminal measurement reports can not be normally sent or a switching reconfiguration command issued by a 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 the network which is most matched with the service requirement for residing, so that the terminal works in a non-optimal state and brings certain experience difference to users in a relatively ideal state.

Detailed Description
As described in the background, configuring a set of mobility management parameters in the same cell may cause the matching of the set of network parameters to different cost terminals to be different, and a set of network parameters may cause the parameters to be mismatched even if the high performance terminal is in a part of the geographical location. The mobile value of some low-cost terminals in the existing network is seriously influenced, or the mobile value of high-performance terminals in some special geographical environment positions in the network is seriously influenced, and finally, the user experience is directly greatly reduced compared with that of the conventional terminals or the reasonable coverage scene of the network. A common set of parameters of the network may also make it difficult for a cell to completely match different application requirements of different terminals.
According to the technical scheme, whether the surrounding environment of the serving cell and/or the neighboring cell is substantially changed or not can be judged through the mobile value of the serving cell and the mobile value of the neighboring cell, and under the condition that the surrounding environment of the serving cell and/or the neighboring cell is substantially changed and the signal quality of the serving cell possibly influences the disconnection of the terminal, namely at least one of the mobile value of the serving cell and the mobile 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 serving cell, the cell switching speed is increased, 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 technical scheme of the invention is that the difference value between the signal measurement value of the adjacent cell and the signal measurement value of the serving cell is used for correcting the signal measurement value of the adjacent 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 serving cell, so that the serving cell is prevented from being switched to the adjacent cell with poor signal quality under the condition that the signal quality of the serving cell is better.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
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 a terminal side, such as a mobile phone, a computer, a tablet computer and other terminal equipment, that is, 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 signal measurement value of a serving cell and a signal measurement value of an adjacent cell;
step S103: acquiring a mobile value of a serving cell and a mobile value of an adjacent cell, wherein the mobile value of the serving cell represents a variation of signal quality of the serving cell in a preset time period, and the mobile value of the adjacent cell represents a variation of the signal quality of the adjacent cell in the preset time period;
step S104: when at least one of the mobility value of the serving cell and the mobility value of the neighboring cell reaches a preset threshold, correcting the signal measurement value of the neighboring cell by using the difference value between the signal measurement value of the neighboring cell and the signal measurement value of the serving cell according to the signal quality of the serving cell;
step S105: and judging whether the corrected signal measurement value of the adjacent cell meets the switching event or not, and reporting a measurement report when the corrected signal measurement value of the adjacent cell meets the switching event.
It should be noted that the sequence numbers of the steps in this embodiment do not represent a limitation on the execution sequence of the steps.
The serving cell Signal measurement value and the neighbor cell Signal measurement value referred to in the embodiments of the present invention may refer to Reference Signal Receiving Power (RSRP), or any other implementable technical index capable of characterizing Signal Quality, such as Reference Signal Receiving Quality (RSRQ), which is not limited in this embodiment of the present invention.
The network sends 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 further include a cell list, a reporting mode, a measurement identifier, an event parameter, and the like.
Specifically, the base station (eNB) may notify the measurement configuration message to a User Equipment (UE) through a measurement configuration (measConfig) cell carried by a Radio Resource Control (RRC) signaling connection reconfiguration (connectionreconfiguration) message, that is, issue the measurement Control. The UE will Measure the current serving cell and determine whether it needs to perform measurement on the neighboring cell according to the s-Measure cell in the rrcconnectionreconfiguration message. The UE may make the following types of measurements: and (3) measurement of same frequency: the measurement is carried out on the downlink carrier frequency of the service cell, and the measurement comprises the following steps: RSRP, RSRQ, path loss (pthlos), etc.; and (3) pilot frequency measurement: measurements are performed on downlink carrier frequencies different from the serving cell, including RSRP, RSRQ, pthlos, etc.
Specifically, the switching event may be an A3/A4/A5 event. Wherein, the A3 event means 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 switching between the intra-frequency and the inter-frequency based on the coverage; the A4 event means that the signal quality of the adjacent cell is higher than an absolute threshold, the event is used for switching based on load, and can be used for load balancing; the a5 event, which is used for intra/inter-frequency coverage based handover, refers to Serving cell signal quality below an absolute threshold of 1(Serving < threshold1) and neighbor cell signal quality above an absolute threshold of 2(Serving > threshold 2).
In the specific implementation of step S101, the terminal may receive measurement configuration information issued by the network side, and acquire a handover event and cell information to be measured.
The terminal can determine the signal measurement value of each cell after the terminal performs measurement according to the configuration of the network side. In the specific implementation of step S102, the terminal may obtain the serving cell signal measurement value and the neighbor cell signal measurement value, where the number of the neighbor cells may be one or multiple.
It should be noted that, if the number of the neighboring cells is multiple, steps S103 to S104 need to be performed on each neighboring cell to correct the neighboring cell measurement value of each neighboring cell respectively.
In the implementation of step S103, the terminal may obtain the mobility value of the serving cell and the mobility value of the neighboring cell. The moving value of the cell indicates the amount of change of the signal quality of the cell within a preset time period, and may indicate the mobility of the terminal in the cell. The higher mobility value of the cell indicates that the terminal has higher mobility in the cell and the surrounding environment of the cell is substantially changed; otherwise, it means that the surrounding environment of the cell has not substantially changed.
Specifically, the terminal may retrieve the mobility value of the serving cell and the mobility value of the neighboring cell from the preset storage space according to the identifiers of the serving cell and the neighboring cell, where the mobility value of each cell may be calculated in advance by the terminal and stored in the preset storage space.
In the specific implementation of step S104, when at least one of the mobility value of the serving cell and the mobility value of the neighboring cell reaches the preset threshold, it indicates that the surrounding environment of at least one of the serving cell and the neighboring cell has substantially changed, and it is necessary to adjust the speed of cell handover, for example, accelerate cell handover or decelerate cell handover. The specific implementation manner of adjusting the cell switching speed is to correct the signal measurement value of the neighboring cell by using the difference between the signal measurement value of the neighboring cell and the signal measurement value of the serving cell according to the signal quality of the serving cell.
Specifically, when the signal quality of the neighboring cell is better than that of the serving cell, the difference between the signal measurement value of the neighboring cell and the signal measurement value of the serving cell is positive, and the signal measurement value of the neighboring cell is corrected by using the difference, so that the signal measurement value of the neighboring cell can be increased, that is, the signal measurement value of the neighboring cell after correction is larger than the signal measurement value of the neighboring cell before correction, so as to accelerate cell handover. On the contrary, when the signal quality of the neighboring cell is poor relative to the signal quality of the serving cell, the difference is negative, and the signal measurement value of the neighboring cell is corrected by using the difference, so that the signal measurement value of the neighboring cell can be reduced, that is, the signal measurement value of the neighboring cell after correction is smaller than the signal measurement value of the neighboring cell before correction, so as to realize the speed reduction cell switching.
In a specific 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 specific 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 trigger condition is that the UE evaluates the report condition according to the measurement report configuration after completing measurement, 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. Measurement report triggering modes are divided into periodic and event triggering. The report content may include: measurement ID, measurement results of the serving cell (RSRP and RSRQ measurement values), measurement results of the neighbor cells (optional).
According to the embodiment of the invention, whether the surrounding environment of the serving cell and/or the neighboring cell is substantially changed or not can be judged through the mobile value of the serving cell and the mobile value of the neighboring cell, and under the condition that the surrounding environment of the serving cell and/or the neighboring cell is substantially changed and the signal quality of the serving cell possibly influences the disconnection of the terminal, namely at least one of the mobile value of the serving cell and the mobile value of the neighboring cell reaches the preset threshold, the signal measurement value of the neighboring cell is corrected according to the signal quality of the serving cell, so that the cell switching speed is increased, the terminal can be switched to the cell with better signal quality more quickly, and the conversation 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 serving 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 serving cell, so that the serving cell is prevented from being switched to the adjacent cell with poor signal quality under the condition that the signal quality of the serving cell is better.
From the view of terminal application requirements, a mobile terminal can be generally divided into two application appeal modes, one mode is that the transmission speed is pursued extremely, the faster the transmission speed is, the better the transmission speed is in unit time, and the transmission quality at each moment is not required too much, such as a real-time monitoring system cloud end transmission module, which is hereinafter referred to as a speed priority terminal application scene; one is an extremely demanding requirement for transmission quality, and the terminal of this type has a high requirement for transmission quality on the basis of a certain guarantee for 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 following steps: if the signal quality of the serving cell is greater than a first threshold, calculating a first product of the difference and a first weight, and calculating the sum of the neighbor cell signal measurement value and the first product as the corrected neighbor cell signal measurement value.
In this embodiment, the fact that the signal quality of the serving cell is greater than the first threshold indicates that the decoding performance of the terminal in the communication range of the serving cell is good, and the probability of dropped calls is low, at this time, when the measured value of the signal of the neighboring cell is corrected, the measured value may not be corrected or the corrected amplitude is small, that is, the value of the first weight may be set to be small, for example, 0.
In one non-limiting embodiment, step S104 shown in fig. 1 may include the following steps: and 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 the sum of the adjacent cell signal measurement value and the second product to serve as the corrected adjacent cell signal measurement value, wherein the second threshold is less than the first threshold, and the second weight is 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 a terminal to drop, and cell handover needs to be accelerated. At this time, when the measured value of the signal of the neighboring cell is corrected, the magnitude of the correction may be increased, that is, the value of the second weight may be set to be larger, for example, the second weight is larger than the first weight.
In one non-limiting embodiment, step S104 shown in fig. 1 may include the following steps: and if the signal quality of the serving cell is less than the second threshold, calculating a third product of the difference and a third weight, and calculating the sum of the neighbor cell signal measurement value and the third product to serve as the corrected neighbor cell signal measurement value, wherein the third weight is greater than the second weight.
Different from the foregoing embodiment, the signal quality of the serving cell in the embodiment of the present invention is smaller than the second threshold, which indicates that the signal quality of the serving cell is poor and cell handover needs to be performed more quickly, and at this time, when the measured value of the signal of the neighboring cell is corrected, the correction amplitude 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 prioritized, and the signal transmission quality depends on the cell signal quality SINR, so the first threshold and the second threshold are set in the above embodiment, and the requirements of different terminals on the signal transmission quality are met.
In one non-limiting embodiment, step S104 shown in fig. 1 may include the following steps: if the signal quality of the serving cell is greater than a second threshold, calculating a fourth product of the difference value and a fourth weight, and calculating a sum of the neighbor cell signal measurement value, the fourth product and a rate parameter as the corrected neighbor cell signal measurement value, wherein the rate parameter is calculated according to the measurement bandwidth of the neighbor cell and the number of downlink samples for the neighbor cell to use in unit time.
The application requirement of the embodiment is different from the foregoing embodiment that the signal transmission quality is prioritized, and in this embodiment, the application requirement of the terminal is that the signal transmission rate is prioritized, and the signal transmission rate is related to the cell signal quality SINR and the number of downlink resources available to the cell.
In specific implementation, the measurement bandwidth of the cell may be obtained from reconfiguration information configured for the terminal by the network side; the number of downlink samples that the cell provides for use in a unit Time may be configured to be 2 if the cell is in a Time Division Duplex (TDD) mode, and may be configured to be 10 if the cell is in a Frequency Division Duplex (FDD) mode.
The rate 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 application scenes based on different terminal application scenes to weight the measured value of the signal of the adjacent cell for evaluating the switching event so as 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 scenes.
Further, the rate parameter is calculated by using the following formula:
integrated inform1 ═ sinoffset × Factor4+10 × lg (MeasPRB/100 × DlSubFrame) × Factor5, where integrated inform1 represents the rate parameter, sinoffset represents the difference, Factor4 represents the fourth weight, Factor5 represents the fifth weight, MeasPRB represents the measurement bandwidth of the neighbor cell, and DlSubFrame represents the number of downlink samples for the neighbor cell to use in a unit time.
In one non-limiting embodiment, step S102 shown in fig. 1 may be preceded by the following steps: acquiring a plurality of signal measurement value pairs of each cell in a first preset time period before the current time, wherein each signal measurement value pair comprises a maximum signal measurement value and a minimum signal measurement value; and selecting the maximum signal measurement value and the minimum signal measurement value in all signal measurement value pairs of each cell in the first preset time period, and calculating a difference value to be used as a moving value of each cell.
It should be noted that the duration of the first preset time period may be set based on a terminal application scenario selection, and a value matched with the network, such as 30s, may be trained in actual use, which is not limited in this embodiment of the present invention.
In this embodiment, the terminal may count RSRP of each cell in a time period (i.e., a first time period) of which the length of each cell from the judgment time is the ObserveTimer1, and then obtain a maximum RSRP and a minimum RSRP (i.e., a maximum signal measurement value and a minimum signal measurement value) of each cell in the time period, which are respectively denoted as maxrrp and MinRSRP.
In calculating the mobility value of the cell, the maximum value and the minimum value of all the maximum signal measurement values and the minimum signal measurement values in the ObserveTimer1 time period are counted as the maximum signal measurement value and the minimum signal measurement value in the ObserveTimer1 time period of the statistical analysis. The movement value of the cell is the difference between the maximum value and the minimum value.
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 a duration of the second preset time period is less than a duration of the first preset time period.
Since the number of cells measured by the terminal is large, and meanwhile, within the observation time period ObserveTimer1, the number of measurement value samples corresponding to each cell is large, if each measurement value corresponding to each cell is stored, and the estimation is performed after the observation time period arrives, a large RSRP storage space is needed, so that to save the storage space, a sliding window processing mode can be adopted, that is, each cell only has an RSRP value within a small time period ObserveTimer2 (i.e., a second preset time period), and then after the time period reaches, the corresponding maximum minimum RSRP is taken as the maximum RSRP value and the minimum RSRP value within the window time period and stored. Then, the terminal counts the maximum value and the minimum value of the maximum and minimum measurement values corresponding to all the observer timer 1/observer timer2 observer timer2 time periods within the observer timer1 time period to serve as the maximum signal measurement value and the minimum signal measurement value within the statistical analysis time period observer 1.
