Background
With the development of Communication technology and the continuous Evolution of 3GPP (3rd Generation Partnership Project) protocol, the ue needs to be compatible with Multiple network systems, such as GSM (Global system for Mobile Communication), EDGE (Enhanced Data Rate for GSM Evolution), TD-SCDMA (Time Division-Synchronous code Division Multiple access), LTE (Long Term Evolution). In order to ensure the communication quality, in the operating process of a UE (User Equipment), the UE needs to measure the signal strength and the signal quality of a neighboring cell uninterruptedly to obtain the communication quality of the neighboring cell, so that when the communication quality of a cell in which the UE is located is poor, the UE can be switched to the neighboring cell with better communication quality.
In the prior art, in the LTE connection mode, the UE needs to measure the neighboring cell within a measurement interval and report the measurement result to the base station within a measurement reporting period. The measurement interval recurs in the time domain with a constant length of time and a fixed repetition period. The process of measuring the neighboring cell by the UE is as follows: the UE acquires a list of cells to be tested issued by a base station; and acquiring the access technology type of the cell to be detected, the frequency point of the cell and the cell identifier in the cell list to be detected. And then, receiving a signal of a cell contained in a frequency point to be measured in each measurement interval contained in the measurement reporting period, measuring the signal quality and the signal strength of the signal, and measuring a measurement signal of the cell contained in the next measurement frequency point in the next measurement interval until the measurement of the cells contained in all the frequency points to be measured is completed.
The following problems may exist in implementing this prior art:
only the cells contained in one frequency point are measured in one measurement interval, so that the measurement times of each cell in a measurement reporting period are less, the condition that the statistical result is inaccurate is easy to occur when the communication quality of each cell is counted based on the measurement result, in addition, the measurement of all the cells to be measured can be completed by a plurality of measurement intervals, and the power consumption is large due to the long time spent for measurement.

Fig. 2A is a flowchart of a signal measurement method according to an embodiment of the present invention. Referring to fig. 2, a method flow provided by the embodiment of the present invention includes:
201. and acquiring a list of cells to be tested.
The list of cells to be tested includes access technology type, frequency point of the cell and cell identification of at least one cell to be tested, and the at least one cell to be tested is a different-frequency cell or a different-system cell of the cell in which the UE is located.
Wherein, the access technology type comprises one or more of LTE, TD-SCDMA, WCDMA, CDMA2000, GSM and EDGE. The cell identity is used to uniquely identify a cell.
The pilot frequency cell is the cell which has the same access technology type as the cell in which the UE is located but different frequency points; the inter-system cell refers to a cell having an access technology type different from that of a cell in which the UE is located.
When the UE is in the connected mode, the base station may periodically or according to a certain rule, obtain a neighboring cell of the cell where the UE is located according to the cell where the UE is located. And then, generating a list of the cells to be tested according to the adjacent cells of the cell in which the UE is positioned, sending the list of the cells to be tested to the UE, and receiving and storing the list of the cells to be tested by the UE.
It should be noted that, in the embodiment of the present invention, the at least one cell to be measured is an effective cell to be measured in the cell to be measured list. Specifically, after acquiring the list of cells to be measured, the UE synchronizes each cell in the list of cells to be measured, where a cell that is successfully synchronized is referred to as an effective cell to be measured.
202. Judging whether the UE is in a static state or not in a timing period; if the UE is in a stationary state, performing the following step 203; if the UE is in a non-stationary state, the following step 205 is performed.
The UE is in two states, a stationary state and a non-stationary state (i.e., a moving state). The stationary state is a relatively stationary state, that is, besides the UE being in an absolute stationary state, when the moving speed of the UE is low or the UE moves only within a small range, the UE may be considered to be in a stationary state within the timing period. The process of determining whether the UE is in the stationary state may be: in a timing period, carrying out frequency offset estimation on the UE to obtain a plurality of frequency offset estimation values; calculating a frequency offset statistic value of the UE according to the plurality of frequency offset estimation values; if the frequency offset statistic value is smaller than a second preset threshold value, determining that the UE is in a static state (namely a relative static state); and if the frequency offset statistic value is not less than a second preset threshold value, determining that the UE is in a non-static state.
The timing period is less than the measurement reporting period specified by the 3GPP protocol to meet the measurement rule specified by the 3GPP protocol, so that the signal measurement of all cells to be measured can be completed in the timing period. The second threshold may be preset by the base station, which is not specifically limited in this embodiment of the present invention.
The algorithm for performing Frequency offset estimation on the UE may be an AFC (Automatic Frequency Control) algorithm. The frequency offset statistic of the UE may be a mean or a variance of multiple frequency offset estimation values, or a combination of the mean and the variance, which is not specifically limited in this embodiment of the present invention.
203. And if the UE is in a static state, calculating the priority of each cell to be tested.
When the UE is in the stationary state, the neighboring cells included in the list of the cells to be measured acquired by the UE from the base station do not change basically, that is, when the UE is in the stationary state, the cells to be measured that the UE needs to measure do not change basically. Therefore, when the UE is in a static state, the priority of each cell to be measured can be calculated, so that signal measurement can be performed according to the priority of the cell to be measured.
The process of calculating the priority of each cell to be measured may be: in at least one cell to be measured, firstly, the priority of a second cell to be measured is determined as the highest priority, the second cell to be measured is a cell with zero measurement times, and each cell in a cell list to be measured is guaranteed to be measured at least once so as to meet the requirement of a protocol. And secondly, acquiring the measurement statistic value, the priority of the access technology type and the measurement times of the third cell to be measured, and calculating the priority of the third cell to be measured according to the measurement statistic value, the priority of the access technology type and the measurement times of the third cell to be measured. And the third cell to be measured is a cell with the measurement frequency not equal to zero. The measurement statistic of the third to-be-measured cell is used to characterize the signal quality and signal strength of the third to-be-measured cell, and the measurement statistic may be measurement data obtained by the UE after measuring the signal of the to-be-measured cell.
The priority of the access technology type may be preset according to the data throughput rate, or preset according to other preset rules, which is not specifically limited in the embodiment of the present invention. The priority of the access technology type can be preset by the base station, and the preset priority of the access technology type is sent to the UE and received and stored by the UE; the UE may also perform the preset operation, which is not specifically limited in this embodiment of the present invention. When the access technology type is preset according to the data throughput rate, the priority of the access technology type with the higher data throughput rate can be set to be higher. For example, the priority of LTE is set to 3, the priority of TDSCDMA is set to 2, the priority of GSM is set to 1, and so on.
The number of the second cells to be measured may be one or more, which is not specifically limited in this embodiment of the present invention. If the number of the second cells to be tested is one, determining the priority of the second cells to be tested as the highest priority; and if the number of the second cells to be tested is more than one, performing priority ranking on each cell in the second cells to be tested according to the measurement statistic value of each cell in the second cells to be tested and the priority of the access technology type. That is, when the number of the second cells to be tested is multiple, priority ranking is performed inside the second cells to be tested. The third cell to be measured needs to be prioritized behind the second cell to be measured, that is, the second cell to be measured is measured in preference to the third cell to be measured. Specifically, a special identifier may be added to the second cell to be measured, where the special identifier is used to indicate that the cell to be measured carrying the special identifier is preferentially measured in the measurement interval.
It should be noted that, in the timing period, after the UE performs signal measurement on any cell to be measured, the measurement times and the measurement statistics of the cell to be measured are recorded, and the detailed process is shown in the following step 204. If the second cell to be measured does not exist in the at least one cell to be measured, that is, the cell with the measurement frequency of zero does not exist, it indicates that each cell to be measured in the at least one cell to be measured has been measured, and the UE directly performs priority ranking on a third cell to be measured with the measurement frequency of non-zero. If no measurement statistic record exists in any cell to be measured, the measurement statistic of the cell to be measured is determined to be zero.
The priority of the third cell to be measured can be calculated according to the following formula:
the priority + y of the access technology type measures the statistics-z of the times; wherein, x, y, z are positive numbers, which can be preset by the UE or the base station, and the embodiment of the present invention does not limit the specific values of x, y, z. Preferably, x may be 10, y may be 5, and z may be 2.
The following illustrates the above procedure for calculating the priority of each cell to be measured:
assuming that there are 5 cells to be measured, before measurement is performed at a certain measurement interval, the measurement times, measurement statistics, and access technology type priorities of the 5 cells to be measured are shown in table 1.

According to the priority calculation method, the cells to be measured with the measurement frequency of zero and the cells to be measured with the measurement frequency of non-zero need to be respectively sequenced, and the priority of the cell to be measured with the measurement frequency of zero is higher than that of the cell to be measured with the measurement frequency of non-zero.
The number of measurements for ID1 cell and ID3 cell is zero, then ID1 cell and ID3 cell are set to the highest priority. Since the access technology type priority of the ID3 cell is higher than that of the ID3 cell, the priority of the ID3 cell with high priority can be set to the highest priority 2 and the priority of the ID1 cell to the highest priority 1.
The measurement times of the ID2 cell, the ID4 cell and the ID5 cell are all not zero, and for example, x may be 10, y may be 5 and z may be 2 in the above formula, the priorities of the ID2 cell, the ID4 cell and the ID5 cell are calculated according to the above formula, and thus:
if the priority of the ID2 cell is 48, the priority of the ID4 cell is 53, and the priority of the ID5 cell is 58, then the results of prioritizing the ID1 cell, the ID2 cell, the ID3 cell, the ID4 cell, and the ID5 cell are shown in table 2, and the cell to be measured with the highest priority is measured in the measurement interval.

It should be noted that, if the priorities of the multiple cells to be measured in the third cell to be measured are obtained through calculation to be the same, the priorities may be sorted according to the access technology type priorities.
204. And according to the priority of each cell to be measured, measuring the signal of a first cell to be measured in each measurement interval contained in the timing period, wherein the first cell to be measured is a first number of cells with the highest priority.
In an embodiment of the invention, the timing period comprises a plurality of measurement intervals. The base station informs the UE of the relevant information of the measurement interval before the UE performs the measurement, including the duration indicated by the measurement interval and the frame position in the protocol. The UE receives and stores information related to the measurement interval. The UE is used for receiving the signal of the cell to be measured in each measurement interval and measuring the signal of the cell to be measured. For each measurement interval, before measuring the signal of the cell to be measured, the UE performs the steps of calculating the priority of each cell to be measured, and sorting the cells to be measured according to the priority. Specifically, after sequencing at least one cell to be measured according to the order of priority from high to low, and after sequencing the priority of each cell to be measured, the process of measuring the cell to be measured by the UE may be: in each measurement interval, determining a first number of cells with the highest priority in the sequencing result as a first cell to be measured; recording the measurement times and measurement parameter values of a first cell to be measured, wherein the measurement parameter values at least comprise the signal quality and the signal strength of the cell to be measured; and calculating the measurement statistic value of the cell to be measured according to the measurement parameter value of the first cell to be measured.
The number of the first cells to be measured, that is, the first number, may be preset by the UE according to the duration of the measurement interval and the time required for measuring each cell to be measured, which is not specifically limited in the embodiment of the present invention. For example, the duration of the measurement interval is 6 milliseconds, and the time required for measuring each cell to be measured is 1 millisecond, so that the number of the first cells to be measured may be 2, 3, 4, 5, and the like.
The first number of cells with the highest priority refers to the first number of cells with the highest priority in the priority ranking. For example, there are 10 cells to be measured in total, and the priority is 10-1 from top to bottom after the sorting. If the number of the first cells to be tested is 4, it is necessary to acquire 4 cells with the highest priority ranking among the 10 cells to be tested, that is, to acquire the cells to be tested with the priorities of 10, 9, 8, and 7.
The measurement statistic value of the cell to be measured is used for representing the communication quality of the cell to be measured. In addition, the signal power of the cell to be measured may also be used to calculate a measurement statistic of the cell to be measured, which is not specifically limited in the embodiment of the present invention.
In the embodiment of the present invention, after the measurement of each measurement interval included in the timing cycle is completed, the measurement is ended. And then reporting the measurement result to the base station according to the reporting time indicated by the timing period.
In another embodiment, the measurement may be ended only after the measurement of a part of the measurement interval included in the timing period is completed, so as to reduce power consumption of the UE due to unnecessary measurement. Specifically, after recording the measurement times and the measurement parameter values of the first cell to be measured, the UE may determine whether the measurement times of the cell to be measured meets the measurement requirement, and if the measurement requirement is met, the measurement is ended, and the process may be: judging whether a second number of designated cells to be tested exist in at least one cell to be tested, wherein the designated cells to be tested are the cells to be tested with the measurement times reaching a first preset threshold value; and if the specified cell to be measured with the second number exists, ending the measurement. The second number may be preset by the base station or preset by the UE, which is not specifically limited in this embodiment of the present invention. For example, if the second number is 2 and the first preset threshold is 3, the measurement may be stopped if there are two cells to be measured with the measurement frequency of 3 in at least one cell to be measured during the measurement.
The above steps 203 to 204 are processes of measuring the cell to be measured when the UE is in a stationary state, and the cell to be measured with the measurement frequency of zero is set as the highest priority, so that the 3GPP protocol specification is satisfied. Furthermore, the cell with better communication quality in at least one cell to be measured is measured for more times, so that the effectiveness of signal measurement is improved. When the UE is in the non-stationary state, the process of performing signal measurement on the cell to be measured is described in detail in steps 205 to 206 below.
205. And if the UE is in a non-static state, acquiring a measurement time period used for measurement of each frequency point in at least one frequency point, and calculating the overlapping times of each measurement time period and other measurement time periods in time for each measurement time period.
The at least one frequency point is a frequency point where at least one cell to be measured is located, the measurement time period is used for indicating a designated time period in the measurement interval, and the designated time period is used for measuring a signal of the cell to be measured corresponding to the measurement time period.
The duration of the specified time period corresponding to each measurement period may be equal or unequal, and the duration indicated by the measurement period may be preset by the UE, for example, 1 millisecond, 2 milliseconds, 3 milliseconds, and the like. The duration indicated by the measurement time interval needs to be longer than the duration occupied by the test sample point of the cell to be tested. The duration of the test sample point of the cell to be tested is different according to different access technology types, for example, the duration of each downlink subframe for LTE, the duration of the training sequence in the TS0 frame for TD-SCDMA, the duration of any more than 64 GSM bits on the BCCH carrier for GSM, and the like.
Since the duration of the specified time period indicated by each measurement period, as well as the position in the measurement interval, may be different, different measurement periods may overlap in time. The embodiment of the invention can calculate the overlapping times of each measuring time period and other measuring time periods in time according to the overlapping conditions of different measuring time periods.
The following illustrates how the number of overlaps of the measurement periods is calculated. Fig. 2B is a schematic diagram showing the measurement periods overlapping in the measurement interval. It is assumed that 5 frequency points correspond to 5 measurement time periods, where measurement time period 1 is the measurement time period of frequency point 1, measurement time period 2 is the measurement time period of frequency point 2, measurement time period 3 is the measurement time period of frequency point 3, measurement time period 4 is the measurement time period of frequency point 4, and measurement time period 5 is the measurement time period of frequency point 5. As shown in fig. 2B, the measurement period 1 overlaps with the measurement periods 2, 3, and 4, the measurement period 2 overlaps with the measurement period 1, the measurement period 3 overlaps with the measurement periods 1 and 4, the measurement period 4 overlaps with the measurement periods 1 and 3, and the measurement period 5 does not overlap with the other measurement periods. According to the overlapping condition of each measurement time interval, the number of overlapping times of the measurement time interval 1 is 3, the number of overlapping times of the measurement time interval 2 is 1, the number of overlapping times of the measurement time interval 3 is 2, the number of overlapping times of the measurement time interval 4 is 2, and the number of overlapping times of the measurement time interval 5 is 0.
206. And measuring the signal of at least one cell to be measured according to the overlapping times of each measuring time interval and other measuring time intervals.
According to the number of times of overlapping each measurement time period with other measurement time periods, the process of measuring the signal of at least one cell to be measured may be: and for the current measurement interval, acquiring a fourth cell to be measured, and adding first mark information for the fourth cell to be measured.
The fourth cell to be measured is a cell to be measured included in the first frequency point, the first frequency point is a frequency point corresponding to a measurement time interval with the least number of times of overlapping with other measurement time intervals, and the first mark information is used for indicating that the fourth cell to be measured is measured in the current measurement interval.
In addition, second marking information is added to the cell to be tested contained in the second frequency point.
And the second frequency point is a frequency point overlapped with the measurement time interval of the first frequency point, and the second marking information is used for indicating that the cell to be measured contained in the second frequency point is not measured in the current measurement interval content.
And then, for the cell to be measured without adding the first mark information or the second mark information, repeating the steps of obtaining the fourth cell to be measured and the subsequent steps until the cell to be measured in the current measurement interval is saturated. Thus, the cell to be measured in the current measurement interval can be measured. And in the subsequent measurement interval, the steps are repeatedly executed until all the cells to be measured carry the first mark information, and the measurement is stopped. That is, when all cells to be measured are measured, the measurement is stopped.
The first flag information and the second flag information may be preset by the UE, which is not specifically limited in this embodiment of the present invention. The saturation of the cell to be measured in the current measurement interval means that no time period remains in the current measurement interval for signal measurement.
The following explains step 206, still taking fig. 2B as an example:
as can be seen from the number of overlapping times of each measurement period calculated in step 205, the measurement period with the least number of overlapping times is 5, and the number of overlapping times is 0, that is, the measurement period 5 does not overlap with other measurement periods. Therefore, the frequency point 5 corresponding to the measurement time interval 5 is determined as the first frequency point, and the cell to be measured included in the frequency point 5 is the fourth cell to be measured. And then, adding first marking information to the cell to be tested contained in the frequency point 5. Since there is no measurement period overlapping with the measurement period 5, the step of adding the second label information to the cell to be measured included in the second frequency point is not performed.
Among the measurement periods to which the first flag information is not added are measurement period 1, measurement period 2, measurement period 3, and measurement period 4. Thereafter, the measurement period with the smallest number of overlaps is selected among the measurement periods 1 to 4. As can be seen from the number of overlapping times of the measurement periods calculated in step 205, the measurement period with the least number of overlapping times is 2, which overlaps with the measurement period 1, and the number of overlapping times is 1. Therefore, the cell to be measured included in the frequency point 2 corresponding to the measurement time interval 2 is determined as the fourth cell to be measured, and the first mark information is added to the fourth cell to be measured. Since the measurement period 1 overlaps with the measurement period 2, the second flag information is added to the cell to be measured included in the measurement period 2. And then, repeating the process for the cell to be measured without adding the first mark information or the second mark information until the cell to be measured in the current measurement interval is saturated. So that the signal measurement can be performed on the cell to be measured which needs to be measured in the current measurement interval.
And in the subsequent measurement interval, the steps are repeatedly executed until all the cells to be measured carry the first mark information, and the measurement is stopped. And then, the UE immediately sends the measurement result to the base station, or sends the measurement result to the base station when the measurement reporting period is reached, which is not specifically limited in the embodiment of the present invention.
It should be noted that, if the number of overlapping times of a plurality of measurement periods is the same, for example, the number of overlapping times of the measurement period 3 and the measurement period 4 shown in fig. 2B is 2, the measurement with the highest priority may be selected to perform measurement according to the priority of the access technology type of the frequency point corresponding to the measurement period, or measurement may be performed in other selection manners, which is not specifically limited in the embodiment of the present invention.
Step 205 and step 206 perform signal measurement on multiple cells to be measured in one measurement interval, so that the UE can complete measurement on all cells to be measured in fewer measurement intervals, thereby improving measurement efficiency and reducing power consumption.
It should be noted that the signal measurement method may be applied in a connected mode of the UE, or may be applied in an idle state of the UE; the system to which the signal measurement method is applied includes, but is not limited to, LTE, TD-SCDMA, WCDMA, CDMA2000, and GSM, and the UE mode and the applicable system to which the method is applied are not specifically limited in the embodiments of the present invention.
According to the method provided by the embodiment of the invention, after the list of the cells to be measured is obtained, the signal of the first cell to be measured including a plurality of cells is measured in each measurement interval included in the timing period, so that the measurement times of the cells to be measured are increased in the timing period, and the measurement accuracy is improved. Moreover, the measurement of all the cells to be measured is completed in fewer measurement intervals, the time required for measurement is short, and the power consumption is reduced. Further, when the UE is determined to be in a static state, the priority of each cell to be measured is calculated, and the cells to be measured with high priority are preferentially measured, so that the cell with good signal quality and high priority can be measured more times, and the measurement accuracy is improved while the measurement effectiveness of the adjacent cell of the different-frequency different-system is ensured.
