Description

Communication method, wireless access network equipment and terminal equipment

Technical field

This application relates to the field of communication technology, and more specifically, to a communication method, wireless access network equipment, and terminal equipment.

Background technique

Paging can be used to notify the terminal equipment to establish a service; or, to notify the terminal equipment of changes in cell system information, so that the terminal equipment can re-read the changed system broadcast message; or, to notify the terminal equipment to receive an earthquake Tsunami warning system (earthquake and tsunami warning system, ETWS) information.

The sending and receiving timing of the paging message needs to be determined according to the paging parameters. The radio access network device uses the paging parameters to calculate the paging timing, and uses the paging timing to send the paging message. The terminal device uses the same paging parameter and calculation method to calculate the paging occasion, and receives the paging message at the paging occasion.

In the prior art, the paging parameters need to be manually configured in advance. After the configuration is completed, the radio access network device determines the paging occasion to send the paging message according to the configured paging parameters, and sends it on the paging occasion Paging message.

However, the existing paging mechanism will cause excessive paging time slot overhead and excessive paging energy consumption.

Summary of the invention

The embodiments of the present application provide a communication method, a radio access network device, and a terminal device, which are used to solve the problems of excessive paging time slot overhead and excessive paging energy consumption in the prior art.

In the first aspect, an embodiment of the present application provides a communication method, which includes:

The radio access network device determines the value of the paging parameter according to the first information and the second information, and sends the value of the paging parameter to the terminal device. The first information is used to indicate the peak value of paging messages from the core network device within the set time, and the second information is used to indicate the paging capability of the radio access network device.

In this method, the peak value of paging messages from the core network device within the set time indicated by the first information can reflect the number of paging messages that need to be processed by the radio access network device, and the paging capability indicated by the second information can reflect the number of paging messages that need to be processed by the radio access network device. The number of paging messages that the access network device can process in a unit time. Based on these two types of information, the radio access network device can determine the paging parameters that match the current system state. When the parameter determines the paging occasion, the paging occasion can be matched with the system state. Based on this, when the paging load is small, the radio access network device can take less paging opportunity to send paging messages, thereby significantly reducing the paging time slot and the overhead of paging energy consumption.

As a possible implementation manner, the radio access network device may determine the value of the paging parameter according to the first information, the second information, and the third information.

Wherein, the third information is used to indicate the system load of the wireless access network device.

In this manner, the third information can reflect the system load of the radio access network device, and the value of the paging parameter is determined in combination with the system load, so that the value of the paging parameter matches the system load.

In this possible implementation manner, when the foregoing system load is less than the first preset threshold, the radio access network device determines the value of the paging parameter according to the first information and the second information.

In this manner, if the system load is less than the above-mentioned first preset threshold, it means that the current system load of the radio access network device is relatively small. In this case, the radio access network device is based on the first information and the second information. Re-determine the value of the paging parameter, so that the paging slot and paging capability can be reduced when the paging load is small. When the current system load of the radio access network equipment is already large, at this time, even if the paging load is small and the occupation of the paging slot is reduced, the original paging slot may also be used for data transmission. Support a large system load, and the system energy consumption cannot be reduced. Therefore, the radio access network device only re-determines the value of the paging parameter based on the first information and the second information when the system load is less than the first preset threshold, thereby determining the paging that matches the system load and the paging load The value of the parameter to ensure that the adjustment of the value of the paging parameter can truly reduce the paging time slot and the overhead of paging energy consumption.

As a possible implementation manner, if the ratio of the peak value of the paging message to the paging capability is less than the second preset threshold, the radio access network device determines that the value of the paging parameter is the first value.

Wherein, in this possible implementation manner, the foregoing first value may be smaller than the current value of the foregoing paging parameter.

In this manner, if the ratio of the above-mentioned paging message peak value to the above-mentioned paging capability is less than the second preset threshold, it indicates that the load status of paging tends to be smaller. In this case, the first paging parameter is determined. A value is less than the current value of the paging parameter, and paging is performed based on the first value, which can reduce time slot overhead and energy consumption overhead.

As a possible implementation manner, if the ratio of the peak value of the paging message to the paging capability is greater than a third preset threshold, the radio access network device determines that the value of the paging parameter is the second value.

Wherein, in this possible implementation manner, the foregoing second value may be greater than the current value of the foregoing paging parameter.

In this manner, if the ratio of the above-mentioned paging message peak value to the above-mentioned paging capability is greater than the third preset threshold, it indicates that the load status of paging tends to be larger. In this case, the second paging parameter is determined. The second value is greater than the current value of the paging parameter, and paging is performed based on the largest value to avoid message delay caused by insufficient resources.

In each of the foregoing possible implementation manners, the paging capability X of the radio access network device can satisfy: X=N*Ns*M/T, where M represents the number of terminal devices that can be paged by a paging message at the same time.

The embodiment of the present application does not limit the application scenarios of the wireless access network device 120 and the terminal device.

The wireless access network device 120 and the terminal device may communicate through a licensed spectrum, or communicate through an unlicensed spectrum, or communicate through a licensed spectrum and an unlicensed spectrum at the same time. The wireless access network device 120 and the terminal device can communicate through the frequency spectrum below 6 gigahertz (gigahertz, GHz), or communicate through the frequency spectrum above 6 GHz, and can also use the frequency spectrum below 6 GHz and the frequency spectrum above 6 GHz at the same time. To communicate. The embodiment of the present application does not limit the spectrum resource used between the radio access network device 120 and the terminal device.

The following describes and introduces paging in conjunction with the mobile communication system architecture shown in Figure 1, taking the NR mobile communication system as an example:

Paging is used to notify terminal equipment to establish services; or, to notify terminal equipment that cell system information has changed, so that terminal equipment can read the changed system broadcast message again; or, to notify terminal equipment to receive ETWS information . Wherein, when it is used to notify the terminal device to establish a service, for example, the terminal device in the idle state or the terminal device in the inactive state may be notified. The terminal device in the idle state refers to a terminal device that resides in a cell under the wireless access network device but has not established a connection with the wireless access network device. A terminal device in the inactive state refers to a terminal device that maintains a connection with the core network device but has not entered the active state.

The paging process is completed through the interaction of core network equipment, wireless access network equipment, and terminal equipment. After the wireless access network equipment receives the paging message from the core network equipment, it uses a preset calculation method based on the paging parameters and terminal equipment identification The paging occasion and beam for sending the paging message are determined, and the determined beam is used to send the paging message at the paging occasion. The terminal device determines the paging occasion to receive the paging message according to the same paging parameters, terminal device identification and the same calculation method as the radio access network, and receives the paging message on the determined beam of the paging occasion. For wireless access network devices and terminal devices, multiple paging parameters are involved in the calculation method for determining the timing of sending or receiving a paging message. These paging parameters include but are not limited to: paging cycle T, paging density N, paging occasion (PO) number Ns per paging frame (PF), synchronization signal block (synchronization signal block) , SSB) The number of beams S. The paging cycle may be a discontinuous reception (DRX) cycle. The paging density N may refer to the number of PFs in a paging cycle T. One PF can be one radio frame, or one PF can also span radio frames. For example, one PF can include 2 radio frames. When the PF straddles the radio frame, the position of the PF indicates the position of the start frame of the PF. Each PF can include Ns POs, and paging messages are sent on these POs. The number of SSB beams may refer to the number of beams that send the same paging message on one PO. In these beams, each beam sends the same paging message, and the directions of the beams are different. Fig. 2 is an example diagram of paging parameters of the NR mobile communication system. As shown in Fig. 2, in a paging cycle T, one offset PF_offset and N PFs may be included. PF_offset represents the offset (also called offset) of the paging frame, which is used to adjust the position of the paging frame in the paging cycle. Exemplarily, N may be half of the number of frames contained in T. A PF includes Ns POs. Ns may be 4, for example. If Ns is 4, and assuming that the PF includes 2 radio frames, in the NR mobile communication system, a radio frame can include 20 time slots, so a PO can include 10 time slots. S beams can be used in each PO to send paging messages. S may be 7, for example. As shown in Figure 2, among the 10 time slots of each PO, 7 time slots can be used for downlink transmission. If S is 7, it can be used on a specific symbol of each time slot used for downlink transmission. A beam in a specific direction sends a paging message. As shown in Figure 2, the beam in one direction is used to send paging messages on the 4th to 6th symbols of time slot 1, and the beam in the other direction is used to send paging messages on the 4th to 6th symbols of time slot 2. Paging messages, and so on, so that the S beams are used to send paging messages in different directions.

It is worth noting that the value of the paging parameter shown in FIG. 2 is only an example, and should not be used as a limitation to the embodiment of the present application.

Taking the radio access network device side as an example, as mentioned above, the radio access network device uses a preset calculation method to determine the paging timing to issue a paging message based on the aforementioned paging parameters and terminal device identification, as described below One possible way of calculation.

First, the radio access network equipment uses the following formula (1) to calculate the PF of the paging terminal equipment:

(SFN+PF_offset)mod T=(Tdiv N)*(UE_ID mod N) (1)

Wherein, SFN represents a system frame number (SFN), and PF_offset represents an offset (also referred to as an offset) of a paging frame, which is used to adjust the position of the paging frame in the paging cycle.

T represents the paging cycle T in the aforementioned paging parameter, and the value of T is the smaller of the DRX broadcast by the system message and the DRX indicated in the paging message.

N represents the paging density N in the aforementioned paging parameters, and N=min(T, nB). Among them, nB represents the total number of PFs in a paging cycle, and nB is a high-level configuration parameter. The radio access network device can broadcast nB to the terminal device through a system message. The value of nB can be any of 4T, 2T, T, T/2, T/4, T/8, T/16, T/32, etc., for example.

UE_ID represents the identification of the terminal equipment, UE_ID=IMSI mod 1024. IMSI is the international mobile subscriber identification number (IMSI) of the terminal device.

div is the divisor function.

The mod function is a remainder function, (SFN+PF_offset) mod T represents the remainder after dividing (SFN+PF_offset) and T.

After obtaining the PF through the above formula (1), the radio access network equipment uses the following formula (2) and Table 1 to calculate the PO of the specific paging terminal equipment:

i_s=floor(UE_ID/N)mod Ns (2)

Among them, i_s represents the index of PO, Ns represents the number of paging occasions Ns of each paging frame in the aforementioned paging parameters, Ns=max(1,nB/T), that is, Ns is 1 and nB/T The larger one, floor() is a round-down function.

After i_s is calculated by the above formula (2), the PO is determined according to i_s based on PF.

On the basis of obtaining the PO based on the above formula (2) and Table 1, the radio access network device can further determine which beams to use on which symbols in the PO according to information such as the number of SSB beams S in the aforementioned paging parameters Send a paging message.

The terminal device side can use the foregoing calculation method to determine how to receive the paging message, which will not be repeated here.

Fig. 3 is an interaction flow chart of sending paging messages based on paging parameters in the prior art. As shown in Fig. 3, the process of sending paging messages based on paging parameters includes:

S301. The radio access network device manually configures paging parameters.

The wireless access device can configure paging parameters through manual configuration during system initialization and other stages. For example, the value of each paging parameter may be manually input, and the radio access network device saves the value of each paging parameter input by the user.

After the paging parameter configuration is completed, the radio access network device determines the timing and beam to send the paging message according to the configured fixed paging parameters in the subsequent paging process, no matter how the system status changes. Until the paging parameters are adjusted again through manual configuration.

Wherein, the system state of the radio access network in the embodiment of the present application may refer to the system load, paging load, etc. of the radio access network. The paging load may refer to the peak value of paging messages received from the core network device within a set time of the radio access network device.

S302. The radio access network device broadcasts the foregoing paging parameters to the terminal device through a system information block 1 (SIB1) message.

Correspondingly, the terminal device receives the paging parameters.

S303: The terminal device determines its own PF and PO based on the paging parameter and the identification of the terminal device.

S304. The terminal device starts the DRX receiving mode.

Among them, in each paging cycle T, the terminal device has one and only one PF and PO for receiving paging messages.

S305. The core network device sends a paging message to the radio access network device.

S306. Based on the paging parameters configured in step S301 and the identification of the terminal device to be paged, the radio access network device uses the foregoing calculation method to determine the PF and PO for sending the paging message.

S307. The radio access network device sends a paging message on the determined PO.

It can be seen from the process shown in Figure 3 that in the prior art, the paging parameters are manually configured in advance. After the configuration is completed, no matter how the system status changes, the radio access network devices follow the configured paging parameters. The paging parameters determine when to send paging messages. When the core network device sends a paging message, it needs to be delivered in all the cells within the tracing area (TA). However, the number of paging messages to be delivered by the core network is huge. For the radio access network device In order to ensure the normal transmission of paging messages, when configuring paging parameters, the paging parameters need to be configured to meet the maximum paging load. Among them, the paging load can be used to indicate the peak value of the paging message of the core network device. The following two problems arise.

First, the paging slot overhead is too large.

In a PO, the radio access network uses all downlink time slots to send paging messages. Taking the PO shown in Figure 2 as an example, a PO contains 10 time slots, including 6 downlink time slots. slot, represented by D in Figure 2), 3 uplink time slots (uplink slot, represented by U in Figure 2), 1 special slot (special slot, represented by S in Figure 2), S can be used as a downlink time slot Therefore, there can be 7 downlink time slots in a PO, and the 7 downlink time slots are all used to send paging messages. The above downlink frame ratio is 1:4 as an example. Assume that the paging cycle T is 128 radio frames, the paging density N is 64, the number of POs in each PF Ns is 1, and the number of SSB beams is 7, as an example, then The number of paging slots is 7. At the same time, the proportion of the downlink time slots occupied by the paging slots (referred to as the proportion of paging slots) is calculated according to the following formula (3):

Proportion of paging slots = N*Ns*S/T total number of downlink slots in the cycle (3)

Substituting the parameters of the above example into the above formula (3), we can get the paging when the uplink and downlink frame ratio is 1:4, the paging cycle T is 128 radio frames, the paging density N is 64, and the number of SSB beams is 7. The paging time slot accounts for 21.88%. It can be seen that in all the downlink time slots, 21.88% of the time slots are used to send paging messages, and the overhead of the paging time slot is relatively high.

Secondly, the energy consumption of paging is high.

Based on the foregoing description, the radio access network determines the paging occasion based on the paging parameters and the identification of the terminal device. Correspondingly, the radio access network device needs to send a paging message at the determined paging occasion. The parameters are manually pre-configured, and the paging occasions thus determined are fixed occasions. Even when the paging load is small, these paging occasions still cannot sleep, which results in high energy consumption for paging in the radio access network.

Based on the above problems, the embodiments of the present application provide a communication method that dynamically determines paging parameters matching the current system state according to the peak value of paging messages of core network equipment and the paging capability of the radio access network. The device and the terminal device respectively determine the timing of sending and receiving paging messages according to the paging parameters, so that the paging timing matches the system state, and the paging time slot can be reduced when the paging load is low, so as to reduce paging. Time slot and paging energy consumption overhead.

The method in the embodiments of the present application can be applied to any mobile communication system, such as an LTE communication system, an NR communication system, and other future communication systems.

The following describes in detail the communication methods provided in the embodiments of the present application through some embodiments. The following embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

In order to facilitate the description of the embodiments of the present application, the following application documents take the NR system as an example to illustrate and introduce the embodiments of the present application.

FIG. 4 is a schematic flowchart of a communication method provided by an embodiment of this application. This embodiment relates to a process in which a radio access network device dynamically adjusts paging parameters based on the first information and the second information. As shown in Figure 4, the method includes:

S401: The radio access network device determines the value of the paging parameter according to the first information and the second information.

Wherein, the above-mentioned first information is used to indicate the peak value of the paging message from the core network device within the set time.

Optionally, the radio access network device can execute this embodiment according to a set period. Illustratively, the radio access network device can execute this embodiment every 5 minutes, and the set period is 5 minutes. , The above set time is 5 minutes. In each set period, the radio access network device continuously monitors the number of paging messages sent by the core network device to the radio access network device in each unit time, and the unit time may be, for example, seconds. When the set period ends, the maximum value of the number of paging messages in the unit time is obtained, and the maximum value is used as the peak value of the paging messages in the current period. Through the peak value of paging messages, the maximum number of pages that may be received by the radio access network device can be known. The paging message peak value may also be referred to as the paging load of the radio access network device in the current cycle.

The foregoing second information is used to indicate the paging capability of the radio access network device.

Optionally, the above-mentioned paging capability may refer to the number of terminal devices that the radio access network device can carry paging to it in a unit time, and the unit may be, for example, seconds. It should be understood that the unit time here may be the same as or different from the unit time for monitoring the number of paging messages sent by the core network device, which is not limited in the embodiment of the present application.

In an example, the radio access network device can calculate the paging capability of the radio access network device through the following formula (4).

X=N*Ns*M/T (4)

Among them, X represents the paging capability, N represents the paging density N, Ns represents the number of POs in each PS, Ns, M represents the number of multiple terminal devices that can be paged by one paging message, and T represents the paging cycle T.

Exemplarily, the foregoing M may be 32, that is, the radio access network device can simultaneously page 32 terminal devices through one paging message.

It can be seen from the above that the peak value of paging messages from the core network device within the set time indicated by the first information can reflect the number of paging messages that need to be processed by the radio access network device, and the paging indicated by the second information The capability can reflect the number of paging messages that the access network equipment can process in a unit time. Based on these two types of information, the radio access network equipment can determine the paging parameters that match the current system status. When the paging parameter determines the paging occasion, it can make the paging occasion match the system state.

It is worth noting that the value of the paging parameter determined through the above process may be the same as the value of the paging parameter currently being used by the radio access network device, or may be the same as the value of the paging parameter currently being used by the radio access network device. The value is different. When they are different, the radio access network device updates the value of the paging parameter stored locally, thereby completing the adjustment of the value of the paging parameter, and executes the following steps to send the value of the paging parameter. When they are the same, the radio access network device does not perform subsequent steps until the value of the paging parameter determined in a subsequent processing cycle changes.

S402: The radio access network device sends the value of the foregoing paging parameter to the terminal device.

As an optional implementation manner, the radio access network device may broadcast the value of the paging parameter to the terminal device through a system information update message.

Exemplarily, the above system information update message may be a SIB1 message.

Optionally, when the radio access network device broadcasts the value of the paging parameter to the terminal device, it may broadcast the paging parameter to the terminal device of each cell of the radio access network device.

After the radio access network device sends the value of the paging parameter to the terminal device, both the radio access network device and the terminal device save the paging parameter matching the system state. After the radio access network device receives the paging message from the core network device, it determines the paging occasion to send the paging message based on the paging parameters, and sends the paging message. The specific process will be described in detail in the following embodiments.

In this embodiment, the peak value of paging messages from the core network device within the set time indicated by the first information can reflect the number of paging messages that need to be processed by the radio access network device, and the paging capability indicated by the second information can reflect the number of paging messages that need to be processed by the radio access network device. The number of paging messages that the access network device can process in a unit time. Based on these two types of information, the radio access network device can determine the paging parameters that match the current system state. When the parameter determines the paging occasion, the paging occasion can be matched with the system state. Based on this, when the paging load is small, the radio access network device can take less paging opportunity to send paging messages, thereby significantly reducing the paging time slot and the overhead of paging energy consumption.

When determining the value of the paging parameter in the above step S401, any one of the following methods can be used for determination.

In the first optional manner, the radio access network device may determine the value of the paging parameter only based on the foregoing first information and second information.

In this optional manner, the radio access network device does not consider other factors, and only determines the value of the paging parameter based on the foregoing first information and second information.

This method can quickly determine the value of the paging parameter that matches the paging load based on the first information and the second information.

In the second optional manner, the radio access network device may determine the value of the paging parameter according to the foregoing first information, second information, and third information.

In an example, the system load of the radio access network device may refer to the number and occupancy rate of resource blocks (resource block, RB) in the radio access network device. In other examples, the aforementioned system load may also refer to the CPU usage rate and memory usage rate of the wireless access network device.

In this optional manner, the radio access network device can continuously monitor the system load of the radio access network device while monitoring the number of paging messages of the core network device as described above. The system load may refer to the peak value of the system load of the wireless access network device per unit time within the aforementioned set time, that is, in each cycle. The unit time may be the same as the unit time for monitoring the number of paging messages of the core network device.

In this optional manner, when the radio access network device determines the value of the paging parameter according to the first information, the second information, and the third information, it can be processed as follows:

If the aforementioned system load is less than the first preset threshold, the radio access network device determines the value of the paging parameter according to the first information and the second information.

Wherein, if the system load is less than the above-mentioned first preset threshold, it means that the current system load of the radio access network device is relatively small. In this case, the radio access network device re-determines the search based on the first information and the second information. The value of the paging parameter can reduce the paging slot and paging capability when the paging load is small. When the current system load of the radio access network equipment is already large, at this time, even if the paging load is small and the occupation of the paging slot is reduced, the original paging slot may also be used for data transmission. Support a large system load, and the system energy consumption cannot be reduced. Therefore, the radio access network device only re-determines the value of the paging parameter based on the first information and the second information when the system load is less than the first preset threshold, thereby determining the paging that matches the system load and the paging load The value of the parameter to ensure that the adjustment of the value of the paging parameter can truly reduce the paging time slot and the overhead of paging energy consumption.

Taking the system load as an example of the RB occupancy rate, an exemplary process for judging whether the system load is less than the foregoing first preset threshold includes:

1. Calculate the number of RBs in each radio frame and record it as totalRbNum.

2. Calculate the number of RBs in the time window for sending common messages in each radio frame including the paging message, and record it as usedRbNum.

3. Calculate the ratio of usedRbNum to totalRbNum, and record the result as usedRbRate_acceptable.

4. Calculate the difference between the actual RB occupancy rate (denoted as usedRbRate_cur) and the above usedRbRate_acceptable calculated by the radio access network equipment. When the difference is less than the first preset threshold, it indicates that the current system load of the radio access network equipment is relatively small. The value of the paging parameter may continue to be determined according to the first information and the second information.

The following describes the specific process of determining the value of the paging parameter according to the first information and the second information in the above two optional manners.

As described above, the first information may indicate the peak value of paging messages from the core network device within a set time, and the second information may indicate the paging capability of the radio access network device. When determining the value of the paging parameter according to the first information and the second information, the value of the paging parameter may be determined according to the ratio of the peak value of the paging message indicated by the first information to the paging capability indicated by the second information. Specifically, it can be done in the following two optional ways.

In the first optional manner, if the radio access network device determines that the ratio of the paging message peak value to the paging capability is less than a second preset threshold, the radio access network device determines that the value of the paging parameter is the first value.

Optionally, the foregoing first value is less than the current value of the paging parameter.

As mentioned above, the above paging message peak refers to the peak value of paging messages sent by the core network device to the radio access network device, and the above paging capability refers to the amount of paging that the radio access network device can carry within a unit time. The number of terminal devices, the ratio of the above-mentioned paging message peak value to the above-mentioned paging capability, can characterize the load status of the radio access network equipment for paging. As an example, the embodiment of the present application may divide the load state used for paging into a normal state, a light load state, and a no-load state. Each state corresponds to a ratio range of the above ratio. It should be understood that the ratios in the corresponding range of the light load state are all smaller than the ratios in the corresponding range of the normal state, and the ratios in the corresponding range of the no-load state are all smaller than the ratios in the corresponding range of the light load state.

In the following embodiments, the load state is the normal state, the light load state, and the no-load state as examples for description. However, it should be understood that this is not a limitation to the embodiments of the present application.

For the normal state, light load state, or no-load state, a set of second preset thresholds and first values can be respectively corresponded. That is, under different load conditions, the second preset threshold value may be different, and the first value may also be different.

Optionally, if the current load state is the normal state, the radio access network device determines that the ratio of the paging message peak value to the paging capability is less than a second preset threshold, and the second preset threshold is the light load Therefore, the radio access network device can determine that the light load state is currently entered, and further, the radio access network device determines that the value of the paging parameter is the first value in the light load state. The first value is smaller than the first value of the radio access network device in the normal state before entering the light load state, that is, the value of the paging parameter in the normal state.

Optionally, if the current load state is the light load state, the radio access network device determines that the ratio of the paging message peak value to the paging capability is less than another second preset threshold, and the second preset threshold is The threshold value of the no-load state, therefore, the radio access network device can determine that the current no-load state is entered, and further, the radio access network device determines that the value of the paging parameter is the first value in the no-load state. The first value is smaller than the first value of the radio access network device in the light load state before entering the no load state, that is, the value of the paging parameter in the light load state.

The following takes the above-mentioned transition from the normal state to the light-load state and from the light-load state to the no-load state as examples to illustrate the specific process when the wireless access network device determines the above-mentioned first value.

As mentioned above, the paging parameters may include: paging cycle T, paging density N, the number of POs per PF Ns, and the number of SSB beams S. Based on this, the foregoing first value may include one or any combination of the foregoing parameters. Several possible first values are listed below. It should be understood that the foregoing first value may also be other than the following situations.

1. The first value only includes the paging density N

In this case, after the radio access network device judges that it enters the light load state from the normal state, it only determines that the paging density N is the paging density in the light load state, and/or judges that it enters the empty state from the light load state. After the load state, only the paging density N is determined as the paging density in the no-load state.

Figure 5 is an example diagram of the paging density N determined after the load status changes. As shown in Figure 5, when the radio access network device is in the normal state, the paging density N is the number of radio frames in the paging cycle T. Half, for example, assuming that the number of radio frames in a paging cycle T is 128, the paging density is 64. When the radio access network device enters the light load state from the normal state, the paging density N is one-fourth of the radio frames in the paging cycle T. When the radio access network device enters the no-load state from the light-load state, the paging density N is one-eighth of the radio frames in the paging cycle T.

When the first value only includes the paging density N, as the load state changes from the normal state to the light load state, and then from the light load state to the no-load state, the paging density N decreases accordingly to match the current system state .

2. The first value only includes the PO number Ns of each PF

In this case, after the wireless access network device judges that it enters the light-load state from the normal state, it only determines that Ns is the Ns in the light-load state, and/or, after judging that the light-load state enters the no-load state, only Make sure that Ns is the Ns in the no-load state.

FIG. 6 is an example diagram of Ns determined after the load state changes. As shown in FIG. 6, when the wireless access network device is in the normal state, Ns is 4. When the wireless access network device enters the light load state from the normal state, Ns is 2. When the wireless access network device enters the no-load state from the light-load state, Ns is 1.

3. The first value only includes the number of SSB beams S

In this case, after the wireless access network device judges that it enters the light-load state from the normal state, it only determines that S is the S in the light-load state, and/or, after judging that it enters the no-load state from the light-load state, only Make sure that S is the S in the no-load state.

Exemplarily, in the normal state, S is 7. When the device judges that it enters the light load state from the normal state after wireless access, it is determined that S is 4, that is, in the light load state, 4 beams are used for transmission in each PO Paging message.

4. The first value includes the paging density N and the number of POs per PF Ns

In this case, after the wireless access network device judges that it enters the light-load state from the normal state, it determines that N is the N in the light-load state and determines that Ns is the Ns in the light-load state, and/or judges that it is the light-load state. After the loaded state enters the no-load state, it is determined to be N in the no-load state and Ns is determined to be the Ns in the no-load state.

Fig. 7 is an example diagram of N and Ns determined after the load state changes. As shown in Fig. 7, when the radio access network device is in the normal state, the paging density N is two of the radio frames in the paging cycle T. One part, at the same time, Ns is 4. When the radio access network device enters the light load state from the normal state, the paging density N is a quarter of the radio frames in the paging cycle T, and at the same time, Ns is 2. When the radio access network device enters the no-load state from the light load state, the paging density N is one-eighth of the radio frames in the paging cycle T, and Ns is 1.

It should be understood that in this case, the aforementioned first value is less than the current value of the paging parameter, which specifically includes: the paging density N is less than the paging density N of the current year, and at the same time, Ns is less than the current Ns.

5. The first value includes the paging density N, the number of POs per PF Ns, and the number of SSB beams S

In this case, after the wireless access network device judges that it enters the light load state from the normal state, it determines that N is N in the light load state, Ns is Ns in the light load state, and S is Ns in the light load state. And/or, after judging that the light-load state enters the no-load state, it is determined that N in the no-load state, Ns is Ns in the no-load state, and S is Ns in the no-load state.

It should be understood that in this case, the aforementioned first value is less than the current value of the paging parameter, which specifically includes: the paging density N is less than the paging density N of the current year, and at the same time, Ns is less than the current Ns, and at the same time, the number of SSB beams The number S is smaller than the current number S of SSB beams.

Based on the foregoing description of the first value, when the radio access network device determines the first value, it may use any one of the foregoing first values, or may also use a combination thereof. The following are examples of several possible determination methods. It should be understood that the wireless access network may also use other determination methods.

In the first example, when the radio access network device determines that the aforementioned ratio is less than the second preset threshold for entering the light-load state, the determined first value only includes the paging density N, and when it is judged that the aforementioned ratio is less than that of entering the no-load state When the second preset threshold is used, the determined first value only includes the paging density N.

In this example, when the radio access network device enters the light load state from the normal state and enters the no-load state from the light load state, only the paging density N is reduced, that is, only the paging density N is reduced to reduce the paging time. The overhead of slot and paging energy consumption.

The following uses an example to illustrate.

Suppose the baseline configuration of the radio access network equipment is: the uplink and downlink frame ratio is 1:4, the paging cycle T is 128 radio frames, the paging density N is 64, the number of POs in each PF Ns is 1, and the number of SSB beams is 1 The number is 7.

In the normal state, the paging parameters are the same as the parameters of the aforementioned baseline configuration. Based on the aforementioned formula (3), it can be obtained that the proportion of the paging time slot in the normal state is 87.55%.

After entering the light-load state from the normal state, the radio access network device determines that N is N in the light-load state, and the value is 32. Based on the aforementioned formula (3), the proportion of the paging time slot in the light-load state can be obtained Is 43.75%.

After entering the no-load state from the light-load state, the radio access network equipment determines that N is N in the no-load state, with a value of 16. Based on the aforementioned formula (3), the paging time slot occupancy in the no-load state can be obtained. The ratio is 21.88%.

In the second example, when the radio access network device determines that the above ratio is less than the second preset threshold for entering the light load state, the determined first value includes the PO number Ns of each PF. When it is determined that the above ratio is less than the entering no-load state When the second preset threshold is set for the state, the determined first value includes the PO number Ns of each PF.

In this example, when the radio access network device enters the light load state from the normal state, or enters the no-load state from the light load state, only the Ns is reduced, that is, the paging time slot and paging energy consumption are reduced only by reducing the Ns. s expenses.

The following uses an example to illustrate.

Assume that the baseline configuration of the radio access network device is: the uplink and downlink frame ratio is 1:4, the paging cycle T is 128 radio frames, the number of POs in each PF is 4, and the number of SSB beams is 7. In addition, the paging density N has been reduced from 64 in the baseline configuration to 16.

When it is determined that the above-mentioned ratio is less than the first preset threshold value in the light-load state and N cannot be lowered, it is determined that Ns is the Ns in the light-load state, and the value is 2. Based on the aforementioned formula (3), it can be obtained that the proportion of the paging time slot in the light load state is 10.94%.

When it is judged that the above ratio is less than the first preset threshold value in the no-load state and N cannot be reduced any more, it is determined that Ns is the Ns in the no-load state, and the value is 1. Based on the aforementioned formula (3), it can be obtained that the proportion of the paging time slot in the light load state is 5.47%.

In the third example, when the radio access network device determines that the above ratio is less than the second preset threshold for entering the light-load state, the determined first value includes the number of SSB beams S. When the second preset threshold is used, the determined first value includes the number S of SSB beams.

In this example, when the radio access network device enters the light-load state from the normal state and enters the no-load state from the light-load state, only S is reduced, that is, the paging time slot and paging energy consumption are reduced only by reducing S. s expenses.

The following uses an example to illustrate.

Assume that the baseline configuration of the radio access network device is: the uplink and downlink frame ratio is 1:4, the paging cycle T is 128 radio frames, and the number of SSB beams is 7. In addition, the paging density N has been reduced from 64 in the baseline configuration to 16, and Ns has been reduced from 4 in the baseline configuration to 1.

When it is judged that the aforementioned ratio is less than the first preset threshold in the no-load state, and N and Ns can no longer be reduced, it is determined that S is the S in the no-load state, and the value is 1. Based on the aforementioned formula (3), it can be obtained that the paging slot ratio in the light load state is 0.08%.

In the fourth example, when the radio access network device determines that the aforementioned ratio is less than the second preset threshold for entering the light-load state, the determined first value includes the paging density N, and when it is judged that the aforementioned ratio is less than the first threshold for entering the no-load state, 2. When the threshold is preset, the determined first value includes the PO number Ns of each PF.

In this example, when the radio access network device enters the light load state from the normal state, only the paging density N is reduced, and when it enters the no-load state from the light load state, only Ns is reduced, that is, by reducing N and Ns at different stages. To reduce the overhead of paging time slot and paging energy consumption.

In the fifth example, when the radio access network device determines that the aforementioned ratio is less than the second preset threshold for entering the light-load state, the determined first value includes the paging density N and the number of POs per PF Ns. When the ratio is less than the second preset threshold for entering the no-load state, the determined first value includes the number S of SSB beams.

In this example, when the radio access network device enters the light load state from the normal state, N and Ns are reduced at the same time, and when the radio access network device enters the no-load state from the light load state, only S is reduced, that is, by reducing N, Ns, and Ns at different stages. S to reduce the overhead of paging time slot and paging energy consumption.

In the second optional manner, if the radio access network device determines that the ratio of the paging message peak value to the paging capability is greater than a third preset threshold, the radio access network device determines that the paging parameter is the second value.

The foregoing second value is greater than the current value of the paging parameter.

In this optional manner, the description is continued by taking the load state including the normal state, the light load state and the no-load state as examples.

For the normal state, light load state or no load state, a set of third preset thresholds and second values can be respectively corresponded. That is, under different load conditions, the third preset threshold may be different, and the second value may also be different.

Optionally, if the current load state is the no-load state, the radio access network device determines that the ratio of the peak value of the paging message to the paging capability is greater than a third preset threshold, and the third preset threshold is Therefore, the radio access network device can determine that the current light load state is entered, and further, the radio access network device determines that the value of the paging parameter is the second value in the light load state. The second value is greater than the second value of the radio access network device in the no-load state before entering the light-load state, that is, the value of the paging parameter in the no-load state.

Optionally, if the current load state is the light load state, the radio access network device determines that the ratio of the paging message peak value to the paging capability is greater than another third preset threshold, and the third preset threshold is entered The threshold value of the normal state, therefore, the radio access network device can determine that it is currently in the normal state, and further, the radio access network device determines that the value of the paging parameter is the second value in the normal state. The second value is greater than the second value in the light load state before the radio access network device enters the normal state, that is, the value of the paging parameter in the light load state.

As an optional implementation manner, the above-mentioned first value in the light-load state and the above-mentioned second value in the light-load state may be the same value.

The following takes the above-mentioned transition from the normal state to the light-load state and from the light-load state to the no-load state as examples to illustrate the specific process when the wireless access network device determines the above-mentioned second value.

As mentioned above, the paging parameters may include: paging cycle T, paging density N, the number of POs per PF Ns, and the number of SSB beams S. Based on this, the aforementioned second value may include one or any combination of the aforementioned parameters. For example, the parameter included in the second value may be one of the several situations listed in the foregoing description of the first value. For example, the first value only includes the paging density N and so on. Or, the above-mentioned second value may also be other parameter combinations, which will not be repeated here.

Correspondingly, based on the foregoing description of the second value, when the radio access network device determines the second value, it may use any of the foregoing second values, or may also use a combination thereof. The following are examples of several possible determination methods. It should be understood that the wireless access network may also use other determination methods.

In the first example, when the radio access network device determines that the above ratio is greater than the third preset threshold for entering the light load state, the determined second value only includes the paging density N, and when it is determined that the above ratio is greater than the first threshold for entering the normal state When three preset thresholds are used, the determined second value only includes the paging density N.

In this example, when the radio access network device enters the light load state from the no-load state, and when it enters the normal state from the light load state, only the paging density N is increased, that is, the paging density N is only increased to meet the actual paging density. Call load demand.

In the second example, when the radio access network device judges that the above ratio is greater than the third preset threshold for entering the light load state, the determined second value includes the PO number Ns of each PF. When it is judged that the above ratio is greater than entering the normal state When the third preset threshold of, the determined second value includes the PO number Ns of each PF.

In the third example, when the radio access network device determines that the above ratio is greater than the third preset threshold for entering the light load state, the determined second value includes the number S of SSB beams, and when it is determined that the above ratio is greater than the first threshold for entering the normal state When three preset thresholds are used, the determined second value includes the number S of SSB beams.

The above describes the process in which the radio access network device determines the value of the paging parameter only based on the first information and the second information, and determines the value of the paging parameter based on the first information, the second information, and the third information. Wherein, when determining the value of the paging parameter according to the first information, the second information, and the third information, as an optional way, only when the system load indicated by the third information is less than the first preset threshold value according to the first The information and the second information re-determine the value of the paging parameter, so that the value of the paging parameter is reduced when the load state of the radio access network device changes from heavy to light, so as to reduce the overhead of paging time slot and paging energy consumption , And to increase the value of the paging parameter when the load state of the radio access network device changes from light to heavy, so as to meet the actual paging load demand.

In a scenario, if the radio access network has followed the above process in a certain period, and the system load is less than the first preset threshold, the value of the paging parameter is reduced according to the first information and the second information, In the next period of this period, the radio access network device detects that the current system load is restored to be greater than or equal to the first preset threshold. In this case, the radio access network device can determine the value of the paging parameter It is the preset initial value.

Optionally, the preset initial value may be a value of a paging parameter that satisfies the maximum system load.

When the system load is greater than or equal to the first preset threshold, it indicates that the system load is large. In this case, the paging parameter is restored to the preset initial value to meet the actual system load demand.

It should be understood that the preset initial value may be the same as or different from the aforementioned first value or second value under a certain load state.

Taking the load state including the normal state, light load state and no-load state as an example, the above preset initial value can be equal to the first value in the normal state, and at the same time, the first value in the normal state is equal to the second value in the normal state .

S807. Maintain the value of the current paging parameter unchanged.

S808: Maintain or restore the value of the paging parameter to a preset initial value.
