Measure and report the measurement results according to the requirements of the network side.

When the terminal is in packet transfer mode (PacketTransferMode), in each time division multiple access (TimeDivisionMultipleAccess, referred to as TDMA) frame, the terminal must measure at least one BCCH carrier once; when the terminal is in packet idle mode (PacketIdleModel), the terminal needs to All BCCH carriers in the BA list are measured once within the specified time.

In addition, the character "/" in this article generally indicates that the contextual objects are an "or" relationship.

FIG. 1 is a flowchart of a cell measurement method provided by Embodiment 1 of the present invention. As shown in Figure 1, the cell measurement method of this embodiment may include the following steps:

101: The terminal receives the broadcast control channel allocation BA list delivered by the network side device, and the BA list includes the neighbor cell information of the serving cell where the terminal is located.

Specifically, the terminal stays in the serving cell, and measures the serving cell and the neighboring cells of the serving cell, for example: measuring the BCCH carrier of the serving cell. In the case of cell reselection.

102: The terminal measures the serving cell, and obtains a measurement result of the serving cell.

In this step, after receiving the BA list issued by the network side equipment, the terminal first measures the signal of the serving cell of the terminal, specifically, the measurement of the received signal quality and signal strength of the serving cell, which belongs to the prior art , which will not be repeated here.

103: If the measurement result of the serving cell meets the first trigger condition, the terminal measures at least one neighboring cell included in the BA list.

Specifically, when the terminal detects that the measurement result of the serving cell satisfies the first trigger condition, the terminal starts measuring at least one of the neighboring cells of the serving cell included in the BA list.

Wherein, at least one neighboring cell of the above-mentioned serving cell may be all neighboring cells in the BA list, and may also be some neighboring cells in the BA list, such as the top-ranked part of the neighboring cells in the BA list, or the BA list in the terminal The part of the neighboring cells with the strongest signal obtained by measuring all the neighboring cells in the terminal, the number of the part of the neighboring cells can be preset inside the terminal, or can be configured by sending a message from the network side.

Wherein, the first trigger condition may include one or more of the following conditions, or the time when one or more of the following conditions is met reaches the first time threshold: the received signal strength RXLEV of the serving cell is less than the first strength threshold; The received signal quality RXQUAL is greater than or equal to the first quality threshold; the number of paging channel decoding failures of the serving cell exceeds the first threshold. Specifically, the first strength threshold is a specific value of the received signal strength of the serving cell, and the first quality threshold is a specific value of the received signal quality of the serving cell, which can be preset inside the terminal, or can be set through The network side sends a message to pre-configure. For different terminals, the above threshold can be set to different values. For example, for some specific terminals, such as M2M terminals with fixed positions such as meter reading, the first threshold can be set to infinity. At this time, if the serving cell If the signal is extremely poor, the paging channel decoding will fail, but since the number of paging channel decoding failures will never be greater than positive infinity, the terminal will not start the measurement of neighboring cells, and the terminal can disconnect the current connection and perform cell Select, select a new cell to reside on instead of reselecting a cell.

For example, assuming that the first trigger condition is that the number of paging channel decoding failures of the serving cell exceeds the first number threshold, when the number of paging channel decoding failures of the serving cell exceeds the first number threshold, it indicates that the channel of the downlink channel where the terminal is located If the condition is poor, the terminal starts the measurement of the neighboring cell, and performs cell reselection according to the measurement result. Specifically, the first count threshold can be set to 3, and the counter is decremented by 1 every time the paging channel fails to be decoded, and when the counter is equal to 0, the measurement of the neighboring cell is started.

For another example, assume that the first trigger condition is that the time when the following conditions are met reaches the first time threshold: the received signal strength RXLEV of the serving cell is less than the first strength threshold; the received signal quality RXQUAL of the serving cell is greater than or equal to the first quality threshold, then , when the measurement result of the serving cell satisfies that the received signal strength RXLEV of the serving cell is less than the first strength threshold, and the received signal quality RXQUAL of the serving cell is greater than or equal to the first quality threshold, the terminal does not start the measurement of the neighboring cell at this time, and After the measurement result of the serving cell simultaneously satisfies the above signal strength and signal quality conditions and the duration reaches the first time threshold, the terminal starts the measurement of the neighboring cell, that is, measures at least one neighboring cell of the serving cell according to the BA list. Wherein, within the time period corresponding to the first time threshold, the terminal can maintain a normal communication connection in the serving cell; and if the first time threshold is exceeded, the probability of cell reselection increases, and the terminal needs to check the service cell. Measure at least one neighboring cell of the cell, so as to perform cell reselection when the quality and strength of the received signal of the serving cell are not satisfied.

It should be noted that the first trigger condition is not limited to the above conditions, and may also include other trigger conditions, such as trigger conditions set according to different types of services used by the terminal, which will not be repeated here.

The cell measurement method provided by the embodiment of the present invention measures the serving cell of the terminal, and if the measurement result of the serving cell satisfies the first trigger condition, the terminal measures at least one neighboring cell included in the BA list, which avoids the terminal measuring the neighboring cell. The frequent measurement of the area greatly reduces the consumption of terminal power.

Optionally, in step 103, the terminal measures at least one neighboring cell included in the BA list, which may specifically include:

If the measurement result of the serving cell meets the fifth trigger condition, the terminal measures the first part of neighboring cells in the BA list; or,

If the measurement result of the serving cell meets the sixth trigger condition, the terminal measures the second part of neighboring cells in the BA list, the number of neighboring cells included in the second part of neighboring cells is greater than the number of neighboring cells included in the first part of neighboring cells, and the number of neighboring cells included in the second part of neighboring cells, and the number of neighboring cells included in the second part of neighboring cells The second part of the neighborhood includes the first part of the neighborhood.

Specifically, when the terminal measures the serving cell, if the measurement result of the serving cell satisfies the fifth trigger condition or the sixth trigger condition, then the terminal performs a measurement on the first part of the neighboring cells or the second part, that is, on different ranges Neighborhoods are measured. It can be understood that the above-mentioned first part of the adjacent area and the second part of the adjacent area are not to divide the adjacent area in the BA list into two parts, but only to define the name of two different adjacent areas. , both the above-mentioned first part of neighboring cells and the second part of neighboring cells may include any neighboring cell in the BA list. For example, the first part of neighboring cells can be part of the neighboring cells in the BA list, for example, it can be some of the top neighboring cells in the BA list, or the signal marked when the terminal measures all the neighboring cells in the BA list Some of the strongest neighbors; the number of neighbors included in the second part of neighbors is greater than the number of neighbors included in the first part, for example, all neighbors in the BA list can be included.

Wherein, the fifth trigger condition may include one or more of the following conditions: the RXLEV of the serving cell is less than the fourth strength threshold and greater than or equal to the fifth strength threshold, and the RXQUAL of the serving cell is less than the fourth quality threshold and greater than or equal to the fifth strength threshold. Quality Threshold. The sixth trigger condition may include one or more of the following conditions: the RXLEV of the serving cell is less than the fifth strength threshold, and the RXQUAL of the serving cell is less than the fifth quality threshold.

Wherein, the fourth intensity threshold, the fifth intensity threshold, the fourth quality threshold and the fifth quality threshold are respectively preset threshold values, and the value of the fifth intensity threshold may be smaller than the value of the first intensity threshold; the fourth The value of the quality threshold may be greater than the value of the first quality threshold. Specifically, when the RXLEV of the serving cell is less than the fourth strength threshold and greater than or equal to the fifth strength threshold, or the RXQUAL of the serving cell is less than the fourth quality threshold and greater than or equal to the fifth quality threshold, it indicates the quality of the signal received by the serving cell Both the intensity and intensity are very good, and it is enough to measure only a few neighbors in the BA table. The RXLEV of the serving cell is less than the fifth strength threshold, or the RXQUAL of the serving cell is greater than or equal to the fourth quality threshold, which means that the service quality of the current cell is not good enough, and there may be a need for cell reselection, so you can measure more in the BA table Some neighboring cells of the terminal to avoid problems with the communication connection of the terminal.

It should be noted that the above fifth and sixth trigger conditions are not limited to the above conditions, and may also include other trigger conditions, such as setting the trigger conditions according to different service types or moving speeds used by the terminal.

In the above embodiment, when the terminal measures the neighboring cells, certain trigger conditions can be set to measure different neighboring cell ranges in the BA list under different circumstances, thereby avoiding unnecessary measurement of the neighboring cells by the terminal. The consumption of terminal power is greatly reduced.

FIG. 2 is a flowchart of a cell measurement method provided by Embodiment 2 of the present invention. As shown in FIG. 2, on the basis of the above-mentioned embodiments, the cell measurement method of this embodiment may further include after step 103:

201: If the measurement result of the serving cell satisfies the second trigger condition, the terminal stops measuring at least one neighboring cell.

Specifically, after the terminal starts measuring neighboring cells, if it detects that the detection result of the serving cell satisfies the second trigger condition, the terminal may stop measuring at least one neighboring cell of the serving cell in step 103 .

Wherein, the second trigger bar may include one or more of the following conditions, or the duration of one or more of the following conditions meets the second time threshold: the RXLEV of the serving cell is greater than or equal to the first strength threshold; the serving cell The RXQUAL of RXQUAL is less than the first quality threshold; the number of successful decoding of the paging channel of the serving cell is less than the first number threshold. The values of the first strength threshold, the first quality threshold, the first number threshold, and the first time threshold may be preset inside the terminal, or may be preconfigured by sending a message from the network side.

Specifically, when the signal strength of the serving cell is greater than or equal to the first strength threshold, or the signal quality of the serving cell is less than the first quality threshold, or the number of successful paging channel decoding is less than the first threshold, it may indicate that the serving cell The quality and strength of the received signal are good, therefore, it is not necessary to detect the signal of the neighboring cell.

For example, when the measurement of neighboring cells is enabled, when the second trigger condition is that the number of successful decodings of the paging channel of the serving cell is less than the first number threshold, and the first number threshold is set to 5, the paging channel When the decoding is successful once, the counter is incremented by 1. When the counter is equal to 5, the measurement of the neighboring cells can be turned off.

For another example, assume that the second trigger bar meets the following condition and reaches the second time threshold: when the RXQUAL of the serving cell is less than the first quality threshold, the terminal simultaneously measures the serving cell and the neighboring cell, and when the measurement of the serving cell As a result, when the RXQUAL of the serving cell is less than the first quality threshold, the terminal still measures the neighboring cell, and when the duration for which the RXQUAL of the serving cell is less than the first quality threshold reaches the second time threshold, the terminal stops measuring the neighboring cell. That is, the measurement of at least one neighboring cell of the serving cell is stopped. Wherein, in the time period corresponding to the second time threshold, if the RXQUAL of the serving cell is always smaller than the first quality threshold, it indicates that the signal quality of the serving cell can continue to be good. In this state, the probability of cell reselection is required is very small, so that the terminal can stop measuring at least one neighboring cell of the serving cell.

It should be noted that the second trigger condition is not limited to the above conditions, and may also include other trigger conditions, such as trigger conditions set according to different service types used by the terminal.

The cell measurement method provided by the embodiment of the present invention measures the serving cell of the terminal and starts to measure the adjacent cell when the measurement result meets the trigger condition, thereby avoiding frequent measurement of the adjacent cell and reducing the power consumption of the terminal .

As a feasible implementation mode, on the basis of the above-mentioned embodiments 1 and 2, after step 102, the terminal may also adjust the measurement period according to the measurement result of the serving cell, which may specifically be:

If the measurement result of the serving cell satisfies the third trigger condition, the terminal extends the measurement cycle of the serving cell and/or at least one neighboring cell; or,

If the measurement result of the serving cell satisfies the fourth trigger condition, the terminal shortens the measurement period of the serving cell and/or at least one neighboring cell.

Specifically, when the terminal measures the serving cell, or both the serving cell and the neighboring cell, if the measurement result of the serving cell meets the third trigger condition or the fourth trigger condition, the terminal extends or shortens the A measurement period for the serving cell and/or at least one neighboring cell.

Optionally, the third trigger condition may include one or more of the following conditions: the RXLEV of the serving cell is less than the second strength threshold and greater than or equal to the third strength threshold, and the RXQUAL of the serving cell is less than the second quality threshold and greater than Or equal to the third quality threshold. The fourth trigger condition may include one or more of the following conditions: the RXLEV of the serving cell is smaller than the third strength threshold, and the RXQUAL of the serving cell is greater than or equal to the second quality threshold.

Wherein, the second strength threshold and the third strength threshold are respectively a specific value of the received signal strength of the serving cell, and the second quality threshold and the third quality threshold are respectively a specific value of the received signal quality of the serving cell, Specifically, it can be pre-set inside the terminal, or it can be pre-configured by sending a message from the network side. When the RXLEV of the serving cell is less than the second strength threshold and greater than or equal to the third strength threshold, or the RXQUAL of the serving cell is less than the second quality threshold and greater than or equal to the third quality threshold, it means that the quality and strength of the signal received by the serving cell are both Very well, the measurement of neighboring cells may not be too frequent. If the RXLEV of the serving cell is less than the third strength threshold, or the RXQUAL of the serving cell is greater than or equal to the second quality threshold, it means that the service quality of the current cell is not good enough, and there may be a need for cell reselection, so it can be shortened. /or the measurement period of the neighboring cell, so as to ensure the normal communication connection of the terminal.

Specifically, the time of the extended or shortened post-measurement cycle can be set according to specific conditions. For example, when extending the measurement period, you can choose to set the terminal to measure the serving cell and neighboring cells only in the frame where its own paging block is located, and keep silent at other times without measurement. When the measurement cycle is shortened, it can be set that the terminal needs to measure at least one cell once in each TDMA frame.

It should be noted that the above third and fourth trigger conditions are not limited to the above conditions, and may also include other trigger conditions, such as trigger conditions set according to different service types used by the terminal.

In the above-mentioned embodiments, when the terminal measures the serving cell and neighboring cells, certain trigger conditions can be set, and the measurement period can be extended or shortened according to different conditions, thereby avoiding frequent measurement of the serving cell and neighboring cells, greatly reducing reduce the consumption of terminal power.

Optionally, on the basis of Embodiment 1 and Embodiment 2, after step 102, the terminal may also adjust the measurement cycle according to the moving speed, specifically:

If the moving speed of the terminal is greater than or equal to the set speed, the terminal extends the measurement cycle of the serving cell and/or at least one neighboring cell; or,

If the moving speed of the terminal is lower than the set speed, the terminal shortens the measurement cycle of the serving cell and/or at least one neighboring cell.

Specifically, the terminal may determine the current moving speed according to its internal speed sensing device, or by obtaining the moving speed of the terminal measured by the network side equipment, which is not limited here. The mobile speed of the terminal may affect the measurement results of the cell. For example, if the mobile speed of the terminal is too fast and the measurement period is too long, there will be a certain lag or delay in the measurement results of the cell, thereby affecting the communication of the terminal. Therefore, different measurement periods may be set according to different moving speeds of the terminals. Wherein, according to different values of the set speed, different measurement periods may be corresponded to.

Specifically, the time of the extended or shortened post-measurement cycle can be set according to specific conditions. For example, when extending the measurement period, you can choose to set the terminal to measure the serving cell and neighboring cells only in the frame where its own paging block is located, and keep silent at other times without measurement. When the measurement cycle is shortened, it can be set that the terminal needs to measure at least one cell once in each TDMA frame.

Optionally, the relationship between the terminal moving speed and the measurement period may also be obtained in the following manner. The network side sends out the correspondence between the measurement period and the speed through broadcast or point-to-point transmission, and the terminal receives and stores the correspondence, and adjusts the measurement period according to the real-time speed status; The speed information of the terminal, and then send the measurement period to the terminal; or, the terminal selects an appropriate measurement period based on its own service type, terminal number or subscription information, for example: for some specific terminals, such as M2M terminals with fixed locations, or even Cell measurement can be omitted at all. If the serving cell receives extremely poor signals and cannot correctly decode downlink data, the terminal can disconnect the current connection and perform "cell selection" instead of cell reselection to select a new cell to reside on. In this case, since the adjacent cell measurement is not performed, it is equivalent to the measurement period being positive infinite.

In the above embodiment, when the terminal measures the serving cell and neighboring cells, the measurement period can be adjusted according to the moving speed of the terminal, thereby avoiding frequent measurement of the serving cell and neighboring cells and greatly reducing the power consumption of the terminal.

As yet another feasible implementation manner, on the basis of the above embodiments, the terminal may also adjust the routing area update period and/or location area update period according to the measurement results of the serving cell, specifically including:

If the measurement result of the serving cell meets the seventh trigger condition, the terminal extends the routing area update period and/or location area update period of the terminal; or,

If the measurement result of the serving cell satisfies the eighth trigger condition, the terminal shortens the routing area update period and/or location area update period of the terminal.

Optionally, the seventh trigger condition includes any one or more of the following combinations: the RXLEV of the serving cell is greater than or equal to the sixth strength threshold, the RXQUAL of the serving cell is less than the sixth quality threshold, and the moving speed of the terminal is lower than a set speed. The eighth trigger condition includes any one or more combinations of the following: the RXLEV of the serving cell is less than the seventh strength threshold, the RXQUAL of the serving cell is greater than or equal to the seventh quality threshold, and the moving speed of the terminal is greater than or equal to the set speed.

Wherein, the sixth strength threshold and the seventh strength threshold are respectively a specific value of the received signal strength of the serving cell, and the sixth quality threshold and the seventh quality threshold are respectively a specific value of the received signal quality of the serving cell. The values of the sixth intensity threshold and the seventh intensity threshold may be equal or unequal; the values of the sixth quality threshold and the seventh quality threshold may be equal or unequal, which is not limited in this embodiment of the present invention.

When the RXLEV of the serving cell is greater than or equal to the sixth strength threshold, or the RXQUAL of the serving cell is less than the sixth quality threshold, or the moving speed of the terminal is lower than the set speed, it means that the quality and strength of the signal received by the serving cell are good, and the terminal The movement is small, and the serving cell basically remains unchanged. Therefore, the routing area update period and/or location area update period of the terminal may not be too frequent. If the RXLEV of the serving cell is less than the seventh strength threshold, or the RXQUAL of the serving cell is greater than or equal to the seventh quality threshold, or the moving speed of the terminal is greater than or equal to the set speed, it means that the service quality of the current cell is not good enough, and the terminal may move It is relatively frequent, and the serving cell changes greatly, so the routing area update period and/or location area update period of the terminal can be shortened.

It should be noted that the above-mentioned seventh and eighth trigger conditions are not limited to the above-mentioned conditions, and may also include other trigger conditions, such as setting trigger conditions according to different types of services used by the terminal.

The cell measurement method provided by the above embodiment measures the serving cell of the terminal, and sets a certain trigger condition according to the measurement result, and starts to measure the adjacent cell after the trigger condition is met for a period of time, and sets the trigger condition at the same time. According to different conditions, the measurement cycle of the cell is extended or shortened, which avoids the frequent measurement of the serving cell and adjacent cells and the frequent switching of the terminal between enabling and disabling the adjacent cell measurement, and greatly reduces the consumption of terminal power.

On the basis of the above embodiments, the terminal may receive a measurement strategy issued by the network side device, and the measurement strategy is used to indicate the identity of the neighboring cell to be measured by the terminal; the terminal may measure the neighboring cell of the serving cell according to the measurement strategy.

Further, the measuring by the terminal on at least one neighboring cell included in the BA list includes: according to the identity of the neighboring cell, the terminal measures the neighboring cell corresponding to the identity of the neighboring cell.

Further, the terminal measuring at least one neighboring cell included in the BA list includes: the terminal measuring at least one neighboring cell according to a measurement cycle.

Wherein, the above-mentioned measurement strategy may be a strategy set by the network side equipment for measuring the serving cell and neighboring cells where the terminal is currently located, and may include measurement cycle, measurement range, etc.; it may also be a certain rule set, that is, set Certain trigger conditions, when certain trigger conditions are met, the serving cell and neighboring cells are measured according to predetermined rules. The measurement strategy may be determined by the network-side device according to information that affects terminal measurement, such as the service type, load, or network standard of the terminal, which is not limited here.
