To facilitate an understanding of the embodiments of the present application, the following terms or contexts are presented in connection with the embodiments of the present application:

taking a 5G system as an example, in the current Voice scheme, when a New air interface (NR) network side does not open Voice (Voice over New Radio, voNR) based on New Radio, or a terminal does not support VoNR, the Voice scheme can only select to fall back to a Long Term Evolution (Long Term Evolution, LTE) network to perform a Voice over Long-Term Evolution (VoLTE) Voice call.

When the network and the terminal support VoNR, a VoNR scheme is selected, and when the network turns on VoNR, but a 5G signal of a terminal device (UE) is weakly covered or uncovered, and is at the edge of the 5G network, an evolved packet system Fallback (Evolved Packet System Fallback, EPS Fallback) is generally adopted to switch or redirect to an LTE network, and a voice service is provided by VoLTE, so as to ensure the continuity of the voice service.

In the existing VoNR and EPS Fallback self-adaptive technical scheme, whether the downlink or the uplink of the UE is in a weak field is mainly judged, and when the UE is in the weak field, a weak field call initiation flow is initiated. The weak call is that the current coverage is poor and the call is dropped, so that the perception of the user is poor and the call needs to fall back to the LTE call. The method comprises the steps of configuring weak field A2 measurement during initial access, judging whether an A2 measurement report is reported when a voice service 5G service quality identifier (5G Quality of Service Identifier,5QI) 1 is established, rejecting 5QI1 establishment when the report is considered as a weak field, adopting an EPS Fallback to an LTE network in a redirection mode, and quickly returning (Fast Return, FR) to an NR cell after the voice service is finished.

The specific flow is as follows:

(1) An initial access process, a switching-in process, a reestablishing-in process, a protocol data unit Session (Protocol Data Unit Session, PDU Session) establishing process and a reestablishing (Resume) process, and configuring A2 measurement of a weak-field initiation call; after reporting the A2 measurement report of the weak-field call, configuring the A1 measurement configuration of the weak-field call;

(2) Setting a downlink weak-field starting call sign after receiving the A2 measurement report, and configuring a weak-field starting call A1 configuration; and after receiving the A1 measurement report, clearing a downlink weak-field call sign and configuring A2 measurement.

(3) Based on the comparison between the uplink road loss measured value and the threshold, judging whether the uplink road loss measured value is in an uplink weak field or not, and placing an uplink weak field marker bit;

(4) When receiving a PDU session modification request (PDU Session Modify Request) message carrying a quality of service Flow (Quality of Service Flow, qoS Flow) of 5QI1 from a core network, a base station judges voice service, if the UE capability supports VoNR, and a VoNR switch of the base station is opened, judges that VoNR service is carried out, if a downlink weak field flag is yes, judges that an EPS Fallback Flow for redirection is carried out, otherwise, judges an uplink weak field flag, and if the uplink weak field flag bit is yes, executes the EPS Fallback Flow for blind redirection; otherwise, the process is carried out according to the original VoNR flow.

However, in the current scheme, after the terminal is required to access the network, the configuration is measured by configuring the weak field A1/A2, the uplink and downlink weak field conditions are detected, when the voice service is established, the self-adaption of the VoNR and EPS Fallback voice schemes is performed based on the downlink/uplink weak field judgment, so that the voice experience of the weak field user is ensured, but when the NR network is in a high-load state, such as more VoNR users, larger network users and larger uplink and downlink network loads, the terminal is not in the weak field, still performs the VoNR service, further increases the network load and influences the user experience.

Therefore, the embodiment of the application provides a processing method for voice service, under the condition that the load of an NR network is relatively high, part of newly accessed voice user evolution packet systems can be dropped (Evolved Packet System Fallback, EPS Fallback) to an LTE network, and when the load of the NR network is relatively low, the newly accessed voice user performs voice (Voice over New Radio, voNR) based on new wireless so as to ensure that the voice call experience of the user is better. Based on network load conditions, voice schemes of VoNR and EPS Fallback are selected adaptively.

Fig. 1 is one of flow diagrams of a processing method of a voice service provided in an embodiment of the present application, and as shown in fig. 1, an embodiment of the present application provides a processing method of a voice service, including:

Step 110, obtaining the voice service to be accessed and the cell load information of the current cell;

specifically, the voice service to be accessed may refer to a voice user access or a newly established voice service. The cell load information may refer to information related to a cell load, and the cell load information may be obtained based on a resource usage condition of a cell. Resource usage may include air interface resources, transmission resources, hardware resources, and the like. The cell load information may include a cell's load, channel load information, the number of user accesses, physical resource block (Physical Resource Block, PRB) usage, control channel element (Common Control Element, CCE), and so on. The bearer information may include signaling radio bearer (Signalling Radio Bearer, SRB) information, data radio bearer information (Data Radio Bearer, DRB), and the like.

It should be understood that the foregoing is illustrative of the present application for ease of understanding and is not to be construed as limiting the present application in any way.

Step 120, carrying out cell load state judgment on the current cell based on the cell load information;

specifically, the cell load state judgment refers to judging whether the cell load state of the current cell is a high load state or a normal load state. For example, a threshold may be set, the cell load information may be compared with the threshold, and the cell load state may be determined to be a high load state if the cell load information exceeds the threshold, and may be determined to be a normal load state if the cell load information is less than or equal to the threshold. It should be appreciated that the specific value of the threshold may be set by the user (e.g., operator) according to the actual situation.

Step 130, in the case that the cell load state is a high load state, dropping the voice service to be accessed back to the LTE network;

specifically, under the condition that the load state of the cell is a high load state, it may be also understood that when the network is in the high load state, the NR base station may refuse to establish a bearer for the voice service to be accessed, and perform VoLTE call by using the UE to the LTE network through the EPS Fallback.

And step 140, carrying the voice service to be accessed based on the voice service VoNR of the new wireless network under the condition that the load state of the cell is a normal load state.

Specifically, when the load state of the cell is a normal load state, it may be also understood that when the network is in a normal load state or a low load state, the NR base station accommodates the establishment of the voice service to be accessed, and performs the VoNR call.

According to the voice service processing method provided by the embodiment of the application, the cell load state is judged through the cell load information, the VoNR and EPS Fallback self-adaptive adjustment is realized based on the cell load state, when an NR network is in a high load state, voice users can directly fall back to LTE when calling, user experience can be ensured, NR network load is reduced, weak field judgment is carried out without configuration measurement after UE is accessed to the network, network load conditions can be monitored in real time when functions are started, and judgment can be carried out when terminal voice service is called. Illustratively, the method of EPS Fallback procedure or VoNR handoff based on some aspect factor is compared: for example, in the method for performing EPS Fallback procedure or VoNR handover based on weak field judgment, there may be a situation that the terminal is not in the weak field, but the cell load is too large, which leads to voice traffic congestion; for example, in a method for performing EPS Fallback procedure or VoNR switching based on voice traffic (for example, the VoNR service is performed in an EPS Fallback procedure when the VoNR service is performed in a large manner, and the VoNR service is performed in a small manner), there may be a small amount of VoNR traffic, but there are other services with higher priorities in a cell, and the resources occupied by the other services with higher priorities are more, which results in less available resources for the VoNR service, and there still exists a situation that the load of the cell is too large, which results in voice traffic congestion. In the two cases, when the cell load state is a high load state, the new voice service is continuously carried, which further aggravates the cell load. The processing method of voice service provided by the embodiment of the application comprehensively considers the whole cell load information, avoids the problem that good voice service cannot be provided for the terminal due to the high load state of the cell, and can also avoid further increasing the cell load.

Illustratively, the number of cell voice users (which may be denoted as CellVoiceUserNum) refers to the number of voice users that are accessed by a cell; the number of cell connected users (which may be referred to as cellconnect usernum) refers to the number of connected users in a cell. The cell resource occupancy may refer to a current time domain resource occupancy and/or a frequency domain occupancy of the cell.

Specifically, the adaptive voice user number threshold and the adaptive connection state user number threshold may be set by a user (such as an operator) according to a network condition.

Illustratively, the number of cell voice users is obtained in real time, and the number of cell voice users is compared with a self-adaptive voice user number threshold:

determining that the cell load state is a high load state under the condition that the number of the cell voice users is larger than a preset self-adaptive voice user number threshold;

under the condition that the number of the cell voice users is smaller than or equal to a preset self-adaptive voice user number threshold, the number of the cell connection state users is obtained in real time, and the number of the cell connection state users is compared with the self-adaptive connection state user number threshold:

determining that the cell load state is a normal load state under the condition that the cell connection state user number is not more than a preset self-adaptive connection state user number threshold;

and under the condition that the number of the cell connection state users is larger than a preset self-adaptive connection state user number threshold, acquiring the cell resource occupancy rate in real time, and judging the cell load state through the cell resource occupancy rate.

According to the voice service processing method provided by the embodiment of the application, when the number of the voice users in the cell is larger than the preset self-adaptive voice user number threshold, the voice users can be directly judged to be in a high-load state, and the judgment of subsequent steps is not needed; when the number of the cell voice users is not more than a preset self-adaptive voice user number threshold, and the number of the cell connection state users is not more than a preset self-adaptive connection state user number threshold, the cell voice users can be directly judged as normal, the judging efficiency is improved, and the judging resources are saved.

Specifically, the sub-items in the cell resource occupancy include: cell uplink PRB occupancy rate, cell downlink PRB occupancy rate, cell uplink CCE occupancy rate and cell downlink CCE occupancy rate.

The preset threshold corresponding to the occupancy rate of the cell uplink PRB is the occupancy rate threshold of the cell uplink PRB;

the preset threshold corresponding to the cell downlink PRB occupancy is a cell downlink PRB occupancy threshold;

the preset threshold corresponding to the cell uplink CCE occupancy rate is a cell uplink CCE occupancy rate threshold;

the preset threshold corresponding to the cell downlink CCE occupancy rate is a cell downlink CCE occupancy rate threshold.

Under the condition that any subitem in the cell resource occupancy rate is larger than a preset threshold corresponding to the subitem, determining that the cell load state is a high load state, namely, determining that the cell load state is the high load state when any one of the following conditions is met:

The occupancy rate of the cell uplink PRB is larger than the occupancy rate threshold of the cell uplink PRB, and the load state of the cell is determined to be a high load state;

the occupancy rate of the cell downlink PRB is larger than the occupancy rate threshold of the cell downlink PRB, and the load state of the cell is determined to be a high load state;

the occupancy rate of the cell uplink CCE is larger than the occupancy rate threshold of the cell uplink CCE, and the load state of the cell is determined to be a high load state;

and determining that the cell load state is a high load state when the cell downlink CCE occupancy rate is larger than a cell downlink CCE occupancy rate threshold.

Otherwise, determining that the load state of the cell is a normal load state means that:

the occupancy rate of the cell uplink PRB is not more than the occupancy rate threshold of the cell uplink PRB, and

the occupancy rate of the cell downlink PRB is not more than the occupancy rate threshold of the cell downlink PRB, and

the occupancy rate of the cell uplink CCE is not more than the occupancy rate threshold of the cell uplink CCE, and

the occupancy rate of the downlink CCE of the cell is not more than the occupancy rate threshold of the downlink CCE of the cell;

and determining the load state of the cell as a normal load state.

Specifically, the detection period may be set by a user (such as an operator) according to actual situations. The cell load information sampling of the current cell means that data related to the cell load, such as resource data, is obtained in real time in a detection period, and the data obtained through sampling is sampling data. Alternatively, the detection period timing may be performed by setting a detection period timer.

It should be understood that the current detection period refers to the current, ongoing detection period. Illustratively, taking an hour as an example of a detection period, each minute is a sampling point. The cell connection state user number and the cell connection state user number obtained in the last minute are the latest sampling data, and the cell connection state user number obtained in the last minute are used as the cell connection state user number and the cell connection state user number of a cell.

60 pieces of sampling data related to the cell resource occupancy rate can be obtained by sampling in one hour, and the cell resource occupancy rate can be obtained by averaging the 60 pieces of sampling data.

Specifically, the cell resource occupancy of the current detection period may be obtained based on the following smoothing formula:

cell resource occupancy = of current detection period

Cell resource occupancy x (1-smoothing factor) for the last detection period

Average value of sampling data in current detection period is multiplied by smoothing factor;

according to the processing method of the voice service, the cell resource occupancy rate of the current detection period can be obtained based on the cell resource obtained in the previous detection period and the sampling data in the current detection period, errors caused by data mutation (such as unstable abrupt rising or falling) of the sampling data in the current detection period are avoided, and the voice service is prevented from falling back to the LTE network due to temporary service sudden increase.

Specifically, when the current detection period is overtime, the cell load state judgment is carried out on the current cell. It should be understood that when the cell load state decision is made on the current cell, the detection period of the next period may be used to sample data synchronously.

Optionally, the method further comprises:

Specifically, when the self-adaptive control switch is started, a detection period timer is started, and cell load information sampling and cell load state judgment are carried out in a detection period; when the self-adaptive control switch is closed, the cell load state judgment is not carried out, and the detection period timer is stopped.

It should be appreciated that the adaptive control switch may be turned on or off by a user (e.g., an operator) depending on the situation.

According to the voice service processing method, the self-adaptive control switch is arranged, so that the VoNR and EPS Fallback self-adaptive switching method provided by the embodiment of the application can be started or closed as required, the flexibility of the scheme is improved, and the scheme is easy to deploy.

In the following embodiments, the number of cell voice users may be denoted as CellVoiceUserNum, the number of cell connection state users may be denoted as cellconnect usernum, and the subitems in the cell resource occupancy rate include: the cell uplink PRB occupancy may be denoted as cellulprbbusage, the cell downlink PRB occupancy may be denoted as celldlprbbusage, the cell uplink CCE occupancy may be denoted as cellulccouse, and the cell downlink CCE occupancy may be denoted as cellulccouse.

the occupancy rate threshold of the cell uplink CCE can be recorded as nrCellAdaptituveUlceUssage Th;

judging whether the adaptive control switch (also called as VoNR and EPS Fallback adaptive control switch) is on:

if the adaptive control switch is on: then

If the cell load nrCellLoadInfo state is nrCellHighLoad, rejecting the radio resource establishment of 5qi=1, returning PDU Session Resource Modification Response, rejecting the reason value being "IMS voice EPS Fallback or RAT Fallback triggered", and executing the EPS Fallback procedure;

otherwise, a Qos flow of 5 qi=1 is admitted, and the VoNR procedure is entered.

If the switch is off: then

Qos flow of 5 qi=1 is admitted and the VoNR procedure is entered.

When the switch state is changed from on to off, the cell load detection is stopped, the VoNR and EPS Fallback self-adaptive process is exited, and the ongoing Fallback flow is not affected.

The cell-level statistics is carried out by a media access control (Medium Access Control, MAC) layer, the second is taken as a sampling unit, and after the statistics is smoothed every second, the PRB occupation condition is reported to the HL periodically.

Setting a judgment threshold: starting a VoNR and EPSFallback adaptive voice user number threshold nrCelladaptive VoiceUserNumTh, starting a VoNR and EPSFallback adaptive connected user number threshold nrCelladaptive ConnectUserNumTh, a cell uplink PRB occupancy threshold nrCelladaptive UlPrBUsageTh, a cell downlink PRB occupancy threshold nrCelladaptive DlPrBUsageTh, a cell uplink CCE occupancy threshold nrCelladaptive UlcceUsUsMar Th, and a cell downlink CCE occupancy threshold nrCelladaptive DlCceUsUsUsUsMar Th.

Setting a detection period nrCellLoadTimer of the cell load, starting a detection period timer when judging that a VoNR and EPS fall back self-adaptive control switch is started, and sampling cell load information in the detection period:

(1) Sampling the number of voice users in the current cell according to seconds, when the detection period is finished, taking CellVoiceUserNum as the latest value when the current detection period is finished, and storing a result record;

(2) Sampling the current cell connection state user number according to seconds, taking the latest value of the current detection period by CellConnectUserNum when the detection period is over, and storing a result record;

(3) And in the period, the high layer HL averages the utilization rate of the cell-level uplink and downlink PRB and the utilization rate of the uplink and downlink CCE, which are reported by the medium access MAC layer. HL directly stores the uplink and downlink PRB utilization rate and CCE utilization rate reported by MAC in the value of the current detection period in nrCellLoadInfo when the uplink and downlink PRB utilization rate and CCE utilization rate reported by MAC are received for the first time, then accumulates and stores the value with the currently stored value each time the cell-level PRB utilization rate and CCE utilization rate reported by MAC are received, records the number of times of MAC reporting in the current detection period, performs average processing in the current detection period when the current detection period arrives, and records and stores CellUlPrbUsage, cellDlPrbUsage, cellUlCceUsage and celluicceusages.

(4) And HL, during the detection period, smoothing the cell-level uplink and downlink PRB utilization rate and the uplink and downlink CCE utilization rate reported by the MAC layer. When the load detection period timer times out, if the load detection period timer does not have the last value for the first time, the stored value is directly used without smoothing, and when the detection period is finished, the uplink and downlink PRB utilization rate and the uplink and downlink CCE utilization rate are smoothed and stored as the value of the cell resource occupancy rate of the current detection period. The smoothing method is as follows: valueaftersmoth=lastvalue =1-alpha + CurrentValue alpha, wherein: lastValue is the value of the cell resource occupancy of the last detection period stored, currentValue is the average value of the sampled data in the current detection period, alpha is the smoothing factor,the K value may be set to a configurable value. After the smoothing process, the record stores the updated CellUlPrbUsage, cellDlPrbUsage, cellUlCceUsage and celluicceusage.

5) After the detection period timer is overtime, judging the load state of the cell:

if CellVoiceUserNum > nrCellAdaptiveVoiceUserNumTh, setting the load state of the cell as nrCellHighLoad;

if CellVoiceUserNum.ltoreq.nrCellAdaptiveVoiceUserNumTh:

if CellConnectUserNum is less than or equal to nrCellAdaptituveConnectUserNumTh, setting the cell load state as nrCellNormamLoad;

if CellConnectUserNum > nrCellAdaptiveConnectUserNumTh:

if CellPrbUssage > nrCellAdaptiveUlPrBUsageTh;

or CellDlPrbUssage > nrCellAdaptiveDlPrBUsageTh;

or CellCceUssage > nrCellAdaptiveUlcceUssage Th;

or CellCceUssage > nrCellAdaptiveDlCceUssage Th,

setting the load state of the cell as nrCellHighLoad;

otherwise: the cell load state is nrCellNormalLoad.

When the VoNR and EPS Fallback self-adaptive control switch is judged to be closed, the cell load state judgment is not carried out, and the detection period timer is stopped.

Compared with the existing low-field VoNR and EPSFallback adaptive schemes, the voice service processing method provided by the embodiment of the application has the following advantages: when the NR network is in a high-load state, the voice user can directly fall back to LTE when calling, so that user experience can be ensured, the load of the NR network is reduced, and the original weak-field strategy is effectively supplemented; the UE does not need to be configured with measurement to carry out weak field judgment after being accessed to a network, the network load condition can be monitored in real time when the function is started, and judgment can be carried out when the terminal voice service calls; after the network deployment, the switch can be started through the self-adaptive control switch, so that the deployment is easy.
