Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a paging method and device.

Background

The access network device may initiate paging to the terminal device for calling the terminal device in one discontinuous reception (Discontinious Reception, DRX) cycle. The terminal device may receive access network device initiated pages within one DRX cycle. One DRX cycle may include a wake-up interval (e.g., on Duration interval) in which the terminal device may receive a page initiated by the access network device, and a sleep interval (e.g., opportunity for DRX interval) in which the terminal device does not receive a page initiated by the access network device, so that the terminal device may save power consumption.

Currently, the access network device may send multiple pages to the terminal device (i.e. repeatedly paging the terminal device), where the terminal device receives the pages using DRX corresponding to the maximum number of paging repetitions, which may result in too long a delay for receiving the paging message by some terminal devices.

3. Uplink communication

In this embodiment of the present application, uplink communication may be referred to as uplink transmission, which refers to a process in which in communication between a terminal device and an access network device, the terminal device sends a signal to the access network device. The signal sent by the terminal device to the access network device may be referred to as an uplink signal or uplink information. The uplink signal includes uplink control information (uplink control information, UCI) and/or uplink data, for example. The uplink control information is used to carry relevant information fed back by the terminal device, such as channel state information (channel state information, CSI), acknowledgement (ACK)/negative acknowledgement (negative acknowledge, NACK), and the like.

5、DRX

The DRX value in the embodiments of the present application may be regarded as one DRX cycle. A DRX cycle may include a wake-up interval in which a terminal device may receive a page sent by an access network device, and a sleep interval in which the terminal device is in a sleep state and does not monitor a control channel. A schematic diagram of a DRX cycle is shown in fig. 1.

6. Coverage class, coverage type

The coverage type in the embodiment of the application is used for characterizing the capability of the terminal equipment to receive the paging message. In particular, terminal devices of different coverage capabilities may have different coverage types. The coverage types may include enhanced coverage and normal coverage, among others. In the normal coverage scenario, the access network device sends a paging message once in one DRX cycle, that is, the terminal device with normal coverage capability may receive a paging message once in one DRX cycle. In the enhanced coverage scenario, the access network device may repeatedly send paging messages multiple times within one DRX cycle, that is, the terminal device with enhanced coverage may receive paging messages multiple times within one DRX cycle. Thus, a small value can be set for the DRX cycle of normal coverage, thereby enabling the terminal device to quickly receive paging messages; and for the DRX cycle of enhanced coverage, a larger value can be set, so that the terminal equipment can complete the reception of all repeated paging messages in one DRX cycle, and the repeated paging messages are prevented from being received in a plurality of DRX cycles.

The coverage grade in the embodiment of the application is used for representing the quality of the wireless environment where the terminal equipment with the enhanced coverage capability is located, and the coverage grade can also represent the quality of the wireless signal received by the terminal equipment with the enhanced coverage capability. The terminal equipment with enhanced coverage capability can determine the corresponding coverage level by comparing the measured reference signal received power (Reference Signal Receiving Power, RSRP) with a preset RSRP threshold. The terminal device with enhanced coverage may have different coverage levels depending on the quality of the wireless environment in which the terminal device with enhanced coverage is located. For example, a terminal device may have a higher coverage level if the quality of the wireless environment in which the terminal device is located is poor. If the quality of the wireless environment in which 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 the terminal equipment, the terminal equipment with high coverage grade can receive paging with larger repetition times. A terminal device with a low coverage level may receive a page with a lower number of repetitions.

The coverage level in the embodiments of the present application may also be a hierarchy that is performed together for normal coverage and enhanced coverage. At this time, the lowest level of the coverage levels may be normal coverage, and the other levels may be the levels of the enhanced coverage.

The foregoing is a simplified description of some of the concepts related to the present application.

At present, for the terminal equipment with enhanced coverage, the access network equipment can configure a maximum paging repetition number, so that the access network equipment can initiate repeated paging to the terminal equipment according to the set maximum paging repetition number, and further, the terminal equipment with enhanced coverage can receive repeated paging initiated by the access network equipment in a DRX period.

However, as the protocols divide the coverage classes of the coverage-enhanced terminal devices, the terminal devices of different coverage classes differ in their ability to receive pages, that is, in the need to receive the maximum number of repetitions of the paging message. For example, a terminal device with a higher coverage level may receive a page with a greater number of repetitions and a terminal device with a lower coverage level may receive a page with a lower number of repetitions. Therefore, if DRX satisfying the maximum number of repetitions is still used, the DRX value of the maximum number of repetitions is generally large, and since the terminal device with a low coverage level does not need such a large DRX value, the large DRX value may cause unnecessary paging delay to the terminal device with a low coverage level, thereby reducing paging efficiency.

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

As shown in fig. 2, a flow chart of an embodiment of a paging method provided in an embodiment of the present application specifically includes the following steps:

in step 201, the first network device transmits DRX configuration information indicating a mapping relationship between a DRX value and a coverage level or a coverage type. Correspondingly, the terminal equipment receives the DRX configuration information.

In particular, the first network device may be an access network device, e.g. a base station. The first network device may broadcast the DRX configuration information, which may thereby be made available to all terminal devices within the cell to receive. Alternatively, the first network device may also send DRX configuration information to a terminal device, whereby the terminal device may be caused to receive the DRX configuration information. The embodiment of the present application is not particularly limited thereto.

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

For convenience of description, the mapping relationship between the DRX value and the coverage level may be referred to as a first mapping relationship, and the mapping relationship between the DRX value and the coverage type may be referred to as a second mapping relationship. An exemplary first mapping may be seen in table 1 and an exemplary second mapping may be seen in table 2. It will be appreciated that table 1 illustrates a scenario of 3 coverage levels by way of example only, and is not limiting of embodiments of the present application, and that in some embodiments, more or fewer coverage levels may be provided.

TABLE 1

Coverage class	DRX value
		Coverage class 1	DRX value 1
Coverage class 2	DRX value 2
		Coverage class 3	DRX value 3

TABLE 2

Coverage type	DRX value
		Enhanced coverage	DRX value 1
Common cover	DRX value 2

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

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

For example, if the terminal device has a normal coverage capability, the terminal device of the normal coverage capability may receive a page of the first network device, and thus, the DRX value corresponding to the normal coverage may be set smaller. That is, the normally covered terminal device may have a small DRX value. If the terminal device has the enhanced coverage capability, the terminal device with the enhanced coverage capability may receive repeated paging of the first network device, and thus, the DRX value corresponding to the enhanced coverage may be set to be larger. That is, the enhanced coverage terminal device may have a larger DRX value.

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

The terminal device may have a higher coverage level if the quality of the wireless environment in which the terminal device is located is poor. At this time, in order to improve the success rate of the terminal device for receiving the paging, the number of repetitions of the paging sent by the first network device is greater, so that the first network device may set a larger DRX cycle, so that the terminal device may have enough time to receive the repeated paging sent by the first network device. That is, higher coverage level terminal devices may have larger DRX values. The quality of the wireless environment in which the terminal device is located is good, the terminal device may have a lower coverage level. At this time, in order to reduce the delay of the terminal device to receiving the paging sent by the first network device, the number of repetitions of the paging sent by the first network device is smaller, so that the first network device may set a smaller DRX cycle, so that the terminal device may receive the repeated paging sent by the first network device in a shorter time. That is, a terminal device of a lower coverage level may have a smaller DRX value.

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

Optionally, step 202 includes step 202a and step 202b when specifically implemented:

step 202a, determining a second DRX value based on the coverage level or coverage type of the terminal device and the DRX configuration information.

Specifically, the terminal device may determine a DRX value corresponding to a coverage level or a coverage type in the DRX configuration information according to the coverage level or the coverage type. For ease of description, the DRX value corresponding to this level of coverage or type of coverage will be referred to herein as the "second DRX value".

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

Optionally, step 202b may include steps 11) and 12) when embodied:

step 11), a plurality of third DRX values are obtained, wherein the plurality of third DRX values are a plurality of DRX values except the second DRX value.

In particular, the plurality of third DRX values may include a terminal device specific DRX (also may be referred to as UE-specific DRX) value and a cell default DRX (also may be referred to as default DRX) value. Optionally, in some embodiments, the plurality of third DRX values may further include a terminal device specific minimum DRX (also referred to as UE-specific DRX-cycle min) value. The terminal device specific DRX value may be obtained after the terminal device has previously negotiated with the second network device, that is, each terminal device may have its corresponding terminal device specific DRX value, which may be, for example, a core network device, such as a mobility management entity (mobile management entity, MME) in a 4G network, or an access and mobility management function (access and mobile management function, AMF) in a 5G network. The cell default DRX value and the terminal device specific minimum DRX value may be sent to the terminal device by the first network device, and illustratively, the cell default DRX value and the terminal device specific minimum DRX value may be broadcast by the first network device, or may be sent to the terminal device by the first network device in a point-to-point manner. If one terminal device has a terminal device specific DRX value, the terminal device may receive the paging message using min (terminal device specific DRX value, cell default DRX value), and if one terminal device does not have a terminal device specific DRX value, the terminal device may receive the paging message using cell default DRX value. In this application, min (a, b) refers to taking the smaller of a and b, and max (a, b) refers to taking the larger of a and b.

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

Alternatively, step 12) may be implemented in the following manner one or two manners when it is implemented.

Mode one

And determining a larger DRX value as a pending DRX value in a specific DRX value and a second DRX value of the terminal equipment, and determining a smaller DRX value as a first DRX value in the pending DRX value and a cell default DRX value.

Specifically, to meet the minimum requirements of communication (i.e., the minimum quality requirements of the wireless environment), the terminal device may first calculate a pending DRX value, which may be used to characterize the DRX value under the minimum communication requirements; wherein the pending drx=max (terminal device specific DRX, second DRX), that is, the pending DRX value is the larger of the terminal device specific DRX value and the second DRX value.

Further, in order not to exceed the DRX threshold value of the cell (e.g., the cell default DRX value), a smaller DRX value may be taken as the first DRX value, e.g., first drx=min (pending DRX, cell default DRX), from among the pending DRX value and the cell default DRX value.

The access network device caches the paging message sent to the terminal device, if the previous DRX cycle cannot send the paging message, the paging message needs to be sent in the next DRX cycle, if the DRX cycle is too long, the delay of the paging message will be too large, in the first mode, because the second DRX value is a DRX value corresponding to the coverage level or the coverage type, the determined DRX can not only enable the selected DRX value to meet the minimum communication requirement, but also enable the selected DRX value to match 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, and because the terminal device can receive the paging message on the paging occasion in each DRX cycle, the smaller DRX value can enable the delay of the terminal device to receive the paging message to be reduced, thereby reducing the delay of the terminal device with low coverage level or the terminal device with ordinary coverage to receive the paging message, and further improving the paging receiving efficiency.

Mode two

The terminal device may first calculate a pending DRX value in a normal coverage scenario. The pending DRX value may be a smaller DRX value among a specific DRX value of the terminal device and a cell default DRX value, for example, pending drx=min (specific DRX of the terminal device, cell default DRX). Then, to meet the minimum communication requirement, the pending DRX value may also be compared with the second DRX value, whereby a larger value may be used as the first DRX. For example, first drx=max (pending DRX, second DRX). By the second mode, the minimum DRX requirement required by the terminal equipment with different coverage grades or different coverage types can be met, so that the power consumption of the terminal equipment can be reduced, and the time delay of the terminal equipment for receiving the paging message is reduced.

It should be noted that, the terminal device does not calculate the first DRX value every time the paging message is received, and illustratively, when parameters related to the paging message (for example, coverage level, coverage type, DRX configuration parameter, etc.) are unchanged, the most recently used first DRX value may be used without repeating the calculation, and the paging occasion for receiving the paging message may be determined using the most recently used first DRX value, thereby receiving the paging message at the paging occasion.

Prior to step 202, the method may further comprise: the terminal device determines a coverage class or a coverage type of the terminal device.

Specifically, the terminal device may first determine the coverage level or the coverage type of the terminal device as follows.

For example, the terminal device may measure RSRP and may calculate the corresponding coverage level according to the calculation rule and the RSRP obtained by the measurement. It may be understood that the calculation rule may be preset in the terminal device, or may be sent by the first network device to the terminal device, which is not limited in particular in the embodiment of the present application.

Further, the coverage type or the coverage level may be stored in the terminal device in advance. It will be appreciated that the coverage type or coverage level may correspond to the coverage capabilities of the terminal device. For example, if the terminal device has an enhanced coverage capability, the terminal device is of an enhanced coverage type; if the terminal equipment has the ordinary coverage capability, the terminal equipment is of an ordinary coverage type.

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

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

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

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

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

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

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

Mode 1

The paging message contains the coverage type or coverage class of the terminal device.

Specifically, after the first network device receives the paging message, if the paging message includes the coverage type or coverage class of the terminal device, it is determined that the coverage type or coverage class in the paging message is the coverage type or coverage class of the terminal device. The paging message may include an identifier of the terminal device.

Mode 2

The paging message contains the RSRP of the terminal device, and the coverage class 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. The coverage level may be obtained according to a preset calculation rule, and it may be understood that the preset calculation rule is kept consistent between the first network device and the terminal device, so that the coverage level obtained by calculation of the first network device and the terminal device may be ensured to be consistent. For example, the first network device may broadcast the preset calculation rule in advance, or send the calculation rule to the terminal device in a point-to-point manner.

In step 205, the first network device sends a paging message to the terminal device using the first DRX value. Correspondingly, the terminal equipment receives the paging message sent by the first network equipment by applying the first DRX value.

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

The access network device caches the paging message sent to the terminal device, if the previous DRX cycle cannot send the paging message, the paging message needs to be sent in the next DRX cycle, and if the DRX cycle is too long, the delay of the paging message is too large. In the embodiment of the invention, the DRX value for receiving the paging message can be determined according to the coverage level or the coverage type of the terminal equipment, so that the coverage level or the coverage type of the terminal equipment is considered in the process of determining the DRX, the determined DRX can be matched with the coverage capability of the terminal equipment, and the method and the device are not used by directly taking a unique maximum DRX value like the prior art, thereby reducing the time delay of the terminal equipment for receiving the paging message.

The above embodiments may be used alone or in combination with each other to achieve different technical effects.
