6. Coverage level and coverage type

The coverage type in this embodiment of the present application is used to characterize the ability of the terminal device to receive paging messages. Specifically, terminal devices with different coverage capabilities may have different coverage types. Wherein, the coverage type may include enhanced coverage and normal coverage. In a normal coverage scenario, an access network device sends a paging message once in a DRX cycle, that is, a terminal device with normal coverage capability can receive a paging message once in a DRX cycle. In the enhanced coverage scenario, the access network device can repeatedly send multiple paging messages within one DRX cycle, that is, a terminal device with enhanced coverage capability can receive multiple repeated paging messages within one DRX cycle information. Therefore, for the DRX cycle of normal coverage, a smaller value can be set, so that the terminal device can quickly receive paging messages; and for the DRX cycle of enhanced coverage, a larger value can be set, so that the terminal device can quickly receive paging messages. The device completes receiving all repeated paging messages in one DRX cycle, avoiding receiving repeated paging messages in multiple DRX cycles.

The coverage level in the embodiment of the present application is used to characterize the quality of the wireless environment where the terminal device with enhanced coverage capability is located, and the coverage level may also reflect the quality of wireless signals received by the terminal device with enhanced coverage capability. Among them, the terminal equipment with enhanced coverage capability can determine the corresponding coverage level by comparing the measured Reference Signal Receiving Power (RSRP) with the preset RSRP threshold. According to the quality of the wireless environment where the terminal device with enhanced coverage capability is located, the terminal device with enhanced coverage capability may have different coverage levels. For example, if the quality of the wireless environment where the terminal device is located is poor, the terminal device may have a higher coverage level. If the quality of the wireless environment where the terminal device is located is good, the terminal device may have a lower coverage level. In order to improve the success rate of receiving paging by terminal equipment, terminal equipment with a high coverage level can receive paging with a relatively large number of repetitions. End devices with low coverage levels can receive paging with a lower number of repetitions.

The coverage level in this embodiment of the present application may also be a grading jointly performed for normal coverage and enhanced coverage. At this time, the lowest level in the coverage levels may be normal coverage, and the other levels may be classifications for enhanced coverage.

The above is a brief introduction to some of the concepts involved in this application.

Currently, for a terminal device with enhanced coverage, the access network device can configure a maximum number of paging repetitions, so that the access network device can initiate repeated paging to the terminal device according to the set maximum number of paging repetitions, which in turn can make The terminal device with enhanced coverage receives multiple repeated paging initiated by the access network device within one DRX cycle.

However, as the protocol divides the coverage levels of terminal devices with enhanced coverage, terminal devices of different coverage levels have different capabilities of receiving paging, that is, they have different requirements for the maximum number of repetitions of receiving paging messages. For example, a terminal device with a higher coverage level may receive paging with a larger number of repetitions, and a terminal device with a lower coverage level may receive paging with a lower number of repetitions. Therefore, if the DRX that satisfies the maximum number of repetitions is still used, the DRX value of the maximum number of repetitions is usually larger. Since the terminal equipment with a low coverage level does not need such a large DRX value, a larger DRX value will give the terminal with a low coverage level The device brings unnecessary paging delay, which reduces the efficiency of paging.

Based on the above problems, the embodiment of the present application proposes a paging method. The paging method provided by the embodiment of the present application will now be described with reference to FIG. 2 .

As shown in Figure 2, it is a schematic flow chart of an embodiment of the paging method provided by the embodiment of the present application, which specifically includes the following steps:

Step 201, the first network device sends DRX configuration information, where the DRX configuration information is used to indicate the mapping relationship between DRX values and coverage levels or coverage types. Correspondingly, the terminal device receives DRX configuration information.

Specifically, the first network device may be an access network device, for example, a base station. The first network device may broadcast DRX configuration information, thereby enabling all terminal devices in the cell to receive the DRX configuration information. Optionally, the first network device may also send DRX configuration information to a terminal device, thereby enabling the terminal device to receive the DRX configuration information. This embodiment of the present application does not specifically limit it.

Wherein, the DRX configuration information is used to indicate the mapping relationship between the DRX value and the coverage level or coverage type, and the coverage type may include enhanced coverage and normal coverage. Wherein, the DRX value refers to the value of one DRX cycle. It can be understood that the DRX value in the DRX configuration information is used to represent the DRX corresponding to the coverage level or coverage type.

Wherein, for the convenience of description, the mapping relationship between the DRX value and the coverage level may be called the first mapping relationship, and the mapping relationship between the DRX value and the coverage type may be called the second mapping relationship. Refer to Table 1 for an exemplary first mapping relationship, and refer to Table 2 for an exemplary second mapping relationship. It can be understood that Table 1 only exemplarily shows scenarios with three coverage levels, but does not constitute a limitation to the embodiment of the present application. In some embodiments, there may be more or less coverage levels.

Table 1

覆盖等级coverage level	DRX值DRX value
覆盖等级1coverage level 1	DRX值1DRX value 1
覆盖等级2coverage level 2	DRX值2DRX value 2
覆盖等级3coverage level 3	DRX值3DRX value 3

Table 2

覆盖类型coverage type	DRX值DRX value
增强覆盖enhanced coverage	DRX值1DRX value 1
普通覆盖normal coverage	DRX值2DRX value 2

Optionally, the DRX value corresponding to a coverage type may be the minimum DRX value allowed by the coverage type, and the DRX value corresponding to a coverage level may be the minimum DRX value allowed by the coverage level.

Optionally, if the DRX configuration information is used to indicate the mapping relationship between the DRX value and the coverage type, the DRX value corresponding to the enhanced coverage in the DRX configuration information is greater than the DRX value corresponding to the normal coverage. For example, referring to Table 2, DRX value 1>DRX value 2.

For example, if the terminal device has normal coverage capability, the terminal device with normal coverage capability can receive a paging from the first network device. Therefore, the DRX value corresponding to normal coverage can be set to be relatively small. That is to say, a terminal device with normal coverage may have a smaller DRX value. If the terminal device has enhanced coverage capability, the terminal device with enhanced coverage capability can receive repeated paging from the first network device, therefore, the DRX value corresponding to enhanced coverage can be set to be relatively large. That is to say, a terminal device with enhanced coverage may have a larger DRX value.

Optionally, if the DRX configuration information is used to indicate the mapping relationship between the DRX value and the coverage level, the DRX value corresponding to the coverage level with a higher coverage level in the DRX configuration information is greater than the coverage level with a lower coverage level. The DRX value corresponding to the level. For example, in the above Table 1, coverage level 1>coverage level 2>coverage level 3, DRX value 1>DRX value 2>DRX value 3.

If the quality of the wireless environment where the terminal device is located is poor, the terminal device may have a higher coverage level. At this time, in order to improve the success rate of receiving paging by the terminal device, the more times the first network device repeats paging, the first network device can set a larger DRX cycle, so that the terminal device can have enough time to receive repeated pages sent by the first network device. That is to say, a terminal device with a higher coverage level may have a larger DRX value. If the quality of the wireless environment where the terminal device is located is relatively good, the terminal device may have a lower coverage level. At this time, in order to reduce the time delay for the terminal device to receive the paging sent by the first network device, the number of repetitions of the first network device sending paging is less, so that the first network device can set a smaller DRX cycle, This enables the terminal device to receive repeated paging sent by the first network device within a relatively short period of time. That is to say, a terminal device with a lower coverage level may have a smaller DRX value.

Step 202, the terminal device determines a first DRX value based on the coverage level or coverage type of the terminal device and DRX configuration information.

Optionally, step 202 includes step 202a and step 202b during specific implementation:

Step 202a, determine a second DRX value based on the coverage level or coverage type of the terminal equipment and DRX configuration information.

Specifically, the terminal device may determine the DRX value corresponding to the coverage level or coverage type in the DRX configuration information according to its coverage level or coverage type. For the convenience of description, the DRX value corresponding to the coverage level or coverage type is referred to as the "second DRX value" herein.

Step 202b, determine the first DRX value according to the second DRX value.

Optionally, step 202b may include step 11) and step 12) during specific implementation:

Step 11), acquiring multiple third DRX values, where the multiple third DRX values are multiple DRX values other than the second DRX value.

Specifically, the plurality of third DRX values may include a terminal device specific DRX (also called UE-specific DRX) value and a cell default DRX (also called default DRX) value. Optionally, in some embodiments, the multiple third DRX values may also include a terminal device specific minimum DRX (also called UE-specific DRX-cycleMin) value. Wherein, the terminal device-specific DRX value may be obtained by the terminal device after pre-negotiation with the second network device, that is, each terminal device may have its corresponding terminal device-specific DRX value. Exemplarily, the second network device may It is a core network device, such as a mobile management entity (MME) in a 4G network, or an access and mobile management function (AMF) in a 5G network. The default DRX value of the cell and the minimum DRX value specific to the terminal device may be sent to the terminal device by the first network device. Exemplarily, the default DRX value of the cell and the minimum DRX value specific to the terminal device may be broadcast by the first network device, or may be broadcast by the first network device The first network device sends the point-to-point transmission to the terminal device, which is not specifically limited in this embodiment of the present application. Among them, if a terminal device has a terminal device-specific DRX value, the terminal device can use min (terminal device-specific DRX value, cell default DRX value) to receive paging messages; if a terminal device does not have a terminal device-specific DRX value, the terminal device The device can use the default DRX value of the cell to receive the paging message. In this application, min(a, b) refers to taking the smaller value of a and b, and max(a, b) refers to taking the larger value of a and b.

Step 12), determining the first DRX value according to multiple third DRX values and the second DRX value. Wherein, the multiple third DRX values include at least a specific DRX value of the terminal equipment and a cell default DRX value.

Optionally, step 12) may be implemented through the following method 1 or method 2 during specific implementation.

method one

Among the specific DRX value and the second DRX value of the terminal device, the larger DRX value is determined as the pending DRX value, and among the pending DRX value and the default DRX value of the cell, the smaller DRX value is determined as the first DRX value.

Specifically, in order to meet the minimum requirements for communication (that is, the minimum quality requirements for the wireless environment), the terminal device can first calculate the pending DRX value, which can be used to represent the DRX value under the minimum communication requirements; where, the pending DRX= max(terminal device specific DRX, second DRX), that is, the pending DRX value is the larger DRX value among the terminal device specific DRX value and the second DRX value.

Further, in order not to exceed the DRX threshold value of the cell (for example, the default DRX value of the cell), the smaller DRX value can be selected as the first DRX value among the undetermined DRX value and the default DRX value of the cell, for example, the first DRX= min (DRX pending, cell default DRX).

The access network device will cache the paging message sent to the terminal device. If the paging message cannot be sent in the previous DRX cycle, it needs to send the paging message in the next DRX cycle. If the DRX cycle is too long, it will cause paging The delay of the call message is too large. In the first method, since the second DRX value is the DRX value corresponding to the coverage level or coverage type, the determination of the pending DRX can not only make the selected DRX value meet the minimum communication requirements, but also make the The selected DRX value matches the coverage capability of the terminal device. The determination of the first DRX value can avoid using the highest DRX to receive the paging message. Since the terminal device will receive the paging message at the paging opportunity in each DRX cycle, so A smaller DRX value will reduce the delay in receiving paging messages for terminal devices, thereby reducing the delay in receiving paging messages for terminal devices with low coverage levels or ordinary coverage, thereby improving the paging efficiency. efficiency.

way two

The terminal device may first calculate a pending DRX value in a common coverage scenario. The pending DRX value may be a smaller DRX value among the specific DRX value of the terminal device and the default DRX value of the cell, for example, pending DRX=min(specific DRX of the terminal device, default DRX of the cell). Next, in order to meet the minimum communication requirement, the pending DRX value can also be compared with the second DRX value, so that the larger value can be used as the first DRX. For example, first DRX=max(pending DRX, second DRX). Through the second method, the minimum DRX requirements required by terminal devices of different coverage levels or different coverage types can be met, thereby reducing the power consumption of the terminal device and reducing the time delay for the terminal device to receive paging messages.

It should be noted that the terminal device does not calculate the first DRX value every time it receives a paging message. Time-varying, without repeated calculations, the most recently used first DRX value can be used, and the paging occasion for receiving a paging message can be determined using the first recently used DRX value, so that the paging message can be received at this paging occasion .

Before step 202, the method may further include: the terminal device determines the coverage level or coverage type of the terminal device.

Specifically, the terminal device may first determine the coverage level or coverage type of the terminal device in the following manner.

Exemplarily, the terminal device may measure the RSRP, and may calculate and obtain the corresponding coverage level according to the calculation rule and the measured RSRP. It can be understood that the calculation rule may be preset in the terminal device, or may be sent to the terminal device by the first network device, which is not specifically limited in this embodiment of the present application.

Furthermore, the coverage type or coverage level can be pre-stored in the terminal device. It can be understood that the coverage type or coverage level may correspond to the coverage capability of the terminal device. For example, if the terminal device has the capability of enhanced coverage, the terminal device is of the enhanced coverage type; if the terminal device has the capability of normal coverage, the terminal device is of the normal coverage type.

Step 203, the second network device sends a paging message to the first network device. Correspondingly, the first network device receives the paging message sent by the second network device.

Specifically, when the second network device initiates paging for the terminal device, a paging message may be generated, and the paging message may be sent to the first network device.

Step 204, the first network device determines the first DRX value based on the coverage level or coverage type of the terminal device and the mapping relationship between the DRX value and the coverage level or coverage type.

Optionally, during specific implementation, step 204 includes: determining the second DRX value based on the coverage level or coverage type of the terminal device, and the mapping relationship between the DRX value and the coverage level or coverage type; determining the first DRX value according to the second DRX value DRX value. The specific implementation manner is similar to that of the terminal device, which can be understood with reference to the above, and will not be repeated here.

Optionally, before step 204, the method further includes: the first network device determines the coverage level or coverage type of the terminal device based on the paging message.

Specifically, after receiving the paging message, the first network device may determine the coverage level or coverage type of the terminal device based on the paging message.

During specific implementation, the first network device may determine the coverage level or coverage type of the terminal device in the following two ways (mode 1 or mode 2).

way 1

The paging message contains the coverage type or coverage level of the terminal equipment.

Specifically, after the first network device receives the paging message, if the paging message includes the coverage type or coverage level of the terminal device, determine that the coverage type or coverage level in the paging message is the coverage type or coverage level of the terminal device. Wherein, the paging message may include the identifier of the terminal device. Exemplarily, the identifier of the terminal device may be, for example, an International Mobile Subscriber Identity (IMSI), or other types of identifiers, which are not specifically limited in this embodiment of the present application.

way 2

The paging message includes the RSRP of the terminal device, and the coverage level of the terminal device is determined based on the RSRP. The first network device may calculate and obtain the coverage level corresponding to the terminal device according to the RSRP of the terminal device carried in the paging message. Wherein, the coverage level can be obtained according to a preset calculation rule. It can be understood that the preset calculation rule is consistent between the first network device and the terminal device, thereby ensuring that the first network device and the terminal device calculate and obtain Consistent level of coverage. For example, the first network device may broadcast the preset calculation rule in advance, or send it to the terminal device in a peer-to-peer manner.

Step 205, the first network device sends a paging message to the terminal device using the first DRX value. Correspondingly, the terminal device applies the first DRX value to receive the paging message sent by the first network device.

Specifically, the first network device sends a paging message to the terminal device at the paging occasion corresponding to the first DRX value, and the terminal device receives the paging message at the paging occasion corresponding to the first DRX value.

The access network device will cache the paging message sent to the terminal device. If the paging message cannot be sent in the previous DRX cycle, it needs to send the paging message in the next DRX cycle. If the DRX cycle is too long, it will cause paging The call delay is too long. In this embodiment of the present application, the DRX value for receiving a paging message can be determined according to the coverage level or coverage type of the terminal device, so that the coverage level or coverage type of the terminal device is considered in the process of determining DRX, so that the determined DRX It matches the coverage capability of the terminal equipment, instead of directly using a unique maximum DRX value as in the prior art, so that the time delay for the terminal equipment to receive the paging message can be reduced.
