Abstract

Provided are a system and method for assuring quality of service (QoS). The system comprises: a detection module; a comparison module; and an update module. The detection module detects whether a user equipment (UE) unit has updated services that need to be assured. If so, a bearer-adjustment QoS of a service bearer channel is acquired according to QoS of all current services that need to be assured of the UE unit. The bearer-adjustment QoS is an adjustment QoS. The comparison module compares a subscription QoS of the UE unit with the adjustment QoS to determine whether the subscription QoS of the UE unit meets QoS requirements of all current services that need to be assured. The update module updates a QoS of the service bearer channel with the adjustment QoS if the subscription QoS does not meet the QoS requirements.

Description

Technical field

This document relates to, but is not limited to, the field of mobile communication technologies, and in particular, to a quality of service (QoS) guarantee system and method.

Background technique

In the era of mobile Internet, operators provide QoS (Quality of Service) guarantee services for user services.

The service QoS guarantee method in the related art includes the following two methods: The first method: the operator attempts to analyze each type of service behavior of the user, and obtains a universal QoS as a weighted average for each type of service, Due to the wide variety of mobile Internet services, unpredictable services, and different requirements for delay, jitter, packet loss rate, and bandwidth requirements of different services, this method is not applicable in mobile communication networks, or it is difficult to find by this method. A fixed algorithm is obtained to obtain QoS for all kinds of changed services, and the total bandwidth resources in the mobile network are limited, and it is impossible to allocate sufficient bandwidth for all services in advance to meet the needs of all users. The second method is: the 3rd Generation Partnership Project (3GPP, the 3rd Generation Partnership Project) network uses the Application Detection Control (ADC) function to perform the service QoS guarantee service. To implement the ADC function, first deploy the policy and billing. The Policy and Charging Implementation Function Module (PCEF) in the Control Architecture (PCC) interacts with the Policy and Charging Rules Function Module (PCRF), and the cooperation between the two modules is complex, and the ADC function needs to establish a proprietary bearer, thus the user The terminal has restrictions, and the terminal bearer control mode (BCM) is required for the terminal and network initiated (UE_NW) mode. At present, only some fourth-generation mobile communication network (4G) terminals support UE_NW mode, and most 2/3G terminals are terminal-initiated (UE_ONLY) mode, and UE_NW mode is not supported.

The service QoS guarantee service in the related art described above cannot dynamically adjust the QoS guarantee service according to the service type, and cannot satisfy the QoS guarantee service of all services.

Embodiments of the invention

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings.

The embodiment of the present invention provides a QoS guarantee system. The embodiment of the present invention may implement a QoS guarantee system based on a mobile network. In the first embodiment, referring to FIG. 1, the QoS guarantee system includes a user equipment (UE) and a gateway (GW). The QoS of the service bearer channel is established between the UE and the GW, and the QoS of the UE is consistent with the GW. The QoS guarantee system further includes:

The detecting module 10 is configured to detect whether the UE updates the to-be-protected service, and when detecting the UE to update the to-be-protected service, obtain the bearer QoS to be adjusted by the service bearer channel according to the QoS of all the to-be-protected services of the UE, and the to-be-adjusted Bearer QoS as the QoS to be adjusted;

In the embodiment of the present invention, the UE may include a user equipment, and the GW may include a gateway, and the QoS is a fixed QoS service. The QoS includes the QoS of the service, the QoS of the UE, the QoS of the bearer channel, and the QoS of the service. To apply for the QoS resource for the service, the QoS resource for the service is terminated. The QoS requirement for each service is pre-configured. The QoS that the UE subscribes to is fixed by the operator for the UE. The QoS bearer resource service, the bearer channel bearer QoS is the total service bearer channel established by the UE and the GW, and the bearer QoS of the bearer channel may be temporary. The bearer QoS of the bearer channel includes QoS on the GW side and QoS on the UE side, when the QoS on the GW side is updated. The UE is notified to the UE in real time through the bearer update mechanism of the 3rd Generation Partnership Project (3GPP) to ensure that the QoS of the UE and the GW are consistent. When the UE is detected to access the to-be-guaranteed service, that is, the UE The bearer QoS establishment with the GW bearer channel is successful, and the successful bearer QoS can be derived from the QoS signed by the UE, and the bearer QoS can also be obtained according to the QoS calculation of the service. The GW side can obtain the QoS of all services, and calculate the QoS of all services to obtain the QoS of the bearer channel.

At a certain moment, the service under the bearer is determined, but the service may be randomly changed at different times. Once the service change is detected, the bearer QoS of the bearer channel needs to be adjusted immediately to adapt to the change of the service. The change of the service includes not only the UE start. The use of a certain service also includes the UE to stop using certain services. When all services are completed, the bearer QoS of the bearer channel is restored to the original state, and all dynamically applied QoS resources are released.

The comparison module 20 is configured to compare the subscription QoS of the UE with the to-be-adjusted QoS to determine whether the subscription QoS of the UE can meet the QoS requirements of all the currently guaranteed services;

The update module 30 is configured to update the service bearer channel QoS to be QoS to be adjusted when the subscription QoS is not met.

In the embodiment of the present invention, when the subscription QoS of the UE cannot carry the QoS requirements of all the to-be-protected services, the QoS of the bearer channel is updated to be the QoS to be adjusted, and the QoS to be adjusted is the optimal QoS parameter of all the services to be guaranteed. The QoS to be adjusted can meet the QoS requirements of all the services to be guaranteed. When the QoS requirement of the UE to be guaranteed is met, the QoS of the bearer channel is restored.

The process of dynamically adjusting the service behavior according to the embodiment of the present invention is as shown in FIG. 6. According to the embodiment, the current service of the UE is a conversational video service, a real-time game service, and an email download service. After the establishment, the QoS of the bearer channel of the three services is successfully established. If the voice service of the service session type is added, the QoS requirements of the four services are obtained. The bearer channel bearer QoS that satisfies the four service requirements, that is, guarantees the service quality of the four services, and calculates the calculated bearer channel QoS of the four services and the subscription QoS of the UE, such as the subscription QoS of the UE. If the requirements of the four types of services are met, the bearer QoS of the bearer channel is restored to be the subscription QoS of the UE. If the QoS of the bearer channel of the three uplink services is updated, the bearer channel of the four types of services is calculated. Bear QoS.

As shown in FIG. 7 , when the GW detects the access of the UE, the GW and the UE bearer channel are successfully established. If the GW detects that the service 1 is started, the GW calculates the bearer channel to be adjusted to be guaranteed. The QoS of the bearer channel to be tuned for the service to be secured 1 is QoS1. If the QoS of the UE is not able to bear the QoS requirement of the service to be secured, the QoS of the GW is updated to be QoS1, and the bearer is updated by the 3GPP. The mechanism notifies the UE side in real time. The QoS on both the UE side and the GW side remains the same. After detecting the start of the service 2, the bearer QoS required to be secured for the service 1 and the service 2 is calculated and the calculated result is taken as the QoS 2. If the QoS requirement of the UE to be secured is still not QoS, the QoS of the GW side is updated to be the bearer QoS2, and the UE is notified in real time by the bearer update mechanism, and the QoS of the UE side and the GW side are consistent. After the end of the service 1 is detected, the update of the to-be-adjusted bearer QoS is only guaranteed to ensure the service 2, and after the end of the service 2 is detected, the QoS of the user subscription is restored.

In this embodiment, the detecting module 10 is configured to: detect whether the UE updates the to-be-protected service, and when detecting the UE to update the to-be-protected service, obtain the bearer QoS to be adjusted according to the QoS of all the to-be-protected services of the UE, and The bearer QoS to be adjusted is used as the to-be-adjusted QoS; the comparison module is configured to: compare the subscribed QoS of the UE with the QoS to be adjusted to determine whether the subscribed QoS of the UE can meet the QoS requirements of all the currently guaranteed services; the update module 30 is configured to: When the subscription QoS is not met, the QoS of the service bearer channel is updated to be QoS to be adjusted. When the service update is detected, the QoS requirements of all the services to be secured are dynamically calculated to meet the requirements of the QoS of each service. The QoS guarantee service is dynamically adjusted according to the service type, and the QoS guarantee service of all services is satisfied.

Optionally, the second embodiment of the QoS guarantee system is provided on the basis of the first embodiment of the QoS guarantee system of the present invention. Referring to FIG. 2, in the second embodiment, the bearer QoS includes parameters of ARP and QCI, The detection module 10 includes:

The service behavior detecting unit 11 is configured to detect whether the UE updates the to-be-guaranteed service;

The first selecting unit 12 is configured to: when detecting that the UE updates the to-be-protected service, select the ARP attribute value with the highest priority among the QoS of the current to-be-protected service of the UE as the preferred ARP value of the QoS to be adjusted;

The ARP (Allocation and Retention Priority) can be used to determine whether the corresponding service bearer can be established and updated successfully when the allocated bearer QoS resource is restricted. The service behavior detecting unit 11 is configured to detect whether the UE updates the to-be-guaranteed service. The QoS guarantee of the to-be-protected service is based on the detection behavior of the service behavior detecting unit, and the first selecting unit 12 is configured to: when detecting that the UE updates the to-be-protected service, select the highest priority of all the QoS in the current to-be-guaranteed service of the UE. The ARP attribute value is used as the preferred ARP value of the QoS to be adjusted. The calculation formula is Priority (ARP(1), ARP(2), ARP(3)...ARP(n)), and the ARP parameter is sent to the eNodeB. It is used for the eNodeB side to decide whether the corresponding bearer can be successfully established. The ARP parameters include the following three conditions: First, the priority of the bearer establishment is successful when the QoS resources are tight. The smaller the ARP value is, the higher the priority is. In the case of QoS resources being tight, the bearer establishment with ARP 1 takes precedence over the ARP 2 The bearer is established. The second is the ARP preemption capability. Whether the QoS resources of other bearers can be preempted if the resources are insufficient. The third is the ability of the ARP to be preempted. If the QoS resources are insufficient, the QoS resources are insufficient. In this case, the bearer will not be triggered to be released to save QoS resources.

The second selecting unit 13 is configured to select a QCI attribute value with the highest priority among the QoS of all the to-be-protected services of the UE as the preferred QCI value of the QoS to be adjusted;

The calculating unit 14 is configured to calculate a required bandwidth of the QoS to be adjusted according to the preferred QCI value.

The QoS Class Identifier (QCI) is a unified identification method for the UE and the GW to transmit services. Different QCI services need to use different bearers. Each QCI corresponds to a set of parameters. The parameters corresponding to the QCI are The second selecting unit 13 is pre-configured on each device, and is configured to select a QCI attribute value with the highest priority among the current QCIs of the UE to be guaranteed as the QCI value of the QoS to be adjusted, Priority (QCI(1), QCI (2), QCI (3) ... QCI (n)) are calculation formulas. The value of the QCI attribute value with the highest priority is determined. The smaller the value of the QCI value, the higher the priority.

In this embodiment, the service behavior detecting unit 11, the first selecting unit 12, the second selecting unit 13, and the calculating unit 14; the values of the QoS parameters to be adjusted are prioritized among the QoS parameters of the service to be secured under the current bearer. The highest level, thus meeting the current QoS guarantee services for all services to be secured, and improving the user experience.

Optionally, based on the second embodiment of the QoS guarantee system of the present invention, a third embodiment of the QoS guarantee system is provided. In the third embodiment, the computing unit 14 is configured to:

When the preferred QCI value is in the first preset interval, the sum of the maximum bit rate (MBR) of all currently to-be-protected services is selected as the MBR of the QoS to be adjusted and/or the guaranteed bit rate of all currently to-be-guaranteed services is selected ( The sum of GBR) as the GBR to be adjusted QoS;

When the highest priority QCI attribute value is the second preset interval, the APN-AMBR whose access point aggregation maximum bit rate (APN-AMBR) is the value of the QoS to be adjusted is selected.

The bearer is divided into a GBR bearer and a non-guaranteed bit rate (Non-GBR) bearer. The GBR bearer guarantees the bit rate bearer, the Non-GBR bearer does not guarantee the bit rate bearer, and the service guarantee system guarantees by QoS resources. The bit rate of the data stream can pass all the time when the GBR does not exceed the GBR. The traffic exceeding the GBR may be discarded when it is congested. When the traffic is not congested, the traffic exceeding the GBR but less than the maximum bit rate (MBR) can pass. The identifiers of the QCIs that are 1 to 4 are GBR bearers, and the identifiers of the QCIs 5 to 9 are Non-GBR bearers. In the embodiment of the present invention, when the QCI attribute value with the highest priority is 1-4, all current services to be secured are selected. The sum of the MBRs is the MBR of the bearer or the GBR of the current service to be secured as the GBR of the QoS to be adjusted. When the value of the highest priority QCI is 5-9, the APN-AMBR with the largest current service is selected. The value is the APN-AMBR to be adjusted QoS. The APN-AMBR can be the maximum bit rate rate of all non-GBR bearers aggregated by one UE in one network access technology (APN). The different scenarios are shown in FIG. 5.

In this embodiment, when the preferred QCI value is in the first preset interval, the sum of the MBRs of all currently to-be-protected services is selected as the MBR of the QoS to be adjusted and/or the sum of the GBRs of all the currently-guaranteed services are selected. As the GBR of the QoS to be adjusted, when the value of the QCI attribute with the highest priority is the second preset interval, the APN-AMBR with the largest current service value is selected as the APN-AMBR of the QoS to be adjusted. Since the bandwidth conforms to the calculation method in the 3GPP protocol, the terminal is applicable to the UE_ONLY mode or the UE_NW mode, and the versatility is stronger.

Optionally, the fourth embodiment of the QoS guarantee system is provided on the basis of the first embodiment of the QoS guarantee system of the present invention. In the fourth embodiment, the detection module (10) further includes:

The obtaining unit (15) is configured to: when detecting that the UE updates the to-be-protected service, perform classification mapping on all current to-be-guaranteed services according to the QCI attribute value;

The second judging unit (16) is configured to determine whether the updated service to be secured is the same as the type of the service to be secured before the update, and when the updated service to be secured is different from the type of the service to be secured before the update, The QoS of all the to-be-protected services of the UE is obtained, and the bearer QoS of the service bearer channel to be adjusted is obtained, and the bearer QoS to be adjusted is used as the QoS to be adjusted.

The obtaining unit (15) is configured to acquire and classify the to-be-protected service according to the QCI attribute value of the service to be secured. If the attribute value of the service QCI is the same, the service has similar requirements for data delay and packet loss rate, such as If the attribute values of the conversational voice service QCI are the same, they can be classified into one category. The conversational video services are also classified into one category according to the attribute values of the QCI; the real-time games are classified into one category; the mailbox service, the FTP download, the www service, etc. And the second judging unit is configured to determine whether the updated service to be secured is the same as the service to be secured before the update, and if not, perform the acquisition and pass all current services to be secured by the UE. The QoS calculates the bearer QoS to be adjusted, and thus can effectively reduce the number of times the bearer QoS is adjusted.

In this embodiment, the obtaining unit 15 is configured to: when detecting that the UE updates the to-be-protected service, perform classification mapping on the current all to-be-guaranteed services according to the QCI attribute value; the second determining unit 16 is configured to determine Whether the updated service to be secured is the same as the type of the service to be secured before the update, and when not the same, the QoS of the service bearer channel to be adjusted is obtained according to the QoS of all the to-be-protected services of the UE, and the The adjusted bearer QoS is used as the QoS to be adjusted. Therefore, when the QoS guarantee service is dynamically adjusted according to the service type to meet the QoS guarantee service of all services, the number of times of adjusting the bearer QoS is reduced, thereby improving the user experience.

Optionally, the fifth embodiment of the QoS guarantee system is provided on the basis of the first embodiment of the QoS guarantee system of the present invention. In the fifth embodiment, the QoS guarantee system further includes:

The recovery module (40) is configured to restore the bearer channel QoS to the subscribed QoS of the UE when it is detected that all current to-be-guaranteed services are completed or when the subscribed QoS of the UE meets the QoS requirements of all currently to-be-guaranteed services. When the subscription QoS of the UE meets the QoS requirements of all the services to be guaranteed, the QoS of the bearer channel is the subscription QoS of the UE, so as to reduce the occupation of the QoS resources of the bearer channel; when the subsequent service is to be guaranteed, timely Provide service bearer channels.

The present invention provides a QoS guarantee method. In the first embodiment of the QoS guarantee method of the present invention, referring to FIG. 3, a service bearer channel QoS is established between a UE and a GW, and the QoS of the UE and the GW are consistent, and the QoS guarantee method is used. include:

Step 10: Detect whether the UE updates the to-be-guaranteed service. When detecting the UE to update the to-be-protected service, obtain the bearer QoS of the service-carrying channel to be adjusted according to the QoS of all the to-be-protected services of the UE, and treat the bearer QoS to be adjusted as Adjust QoS;

In the embodiment of the present invention, the UE may include a user equipment, where the GW may be a gateway, and the QoS is a fixed service quality assurance service. The QoS includes the QoS of the service, the QoS of the UE subscription, the QoS of the bearer channel, and the QoS of the service is started. To apply for the QoS resource for the service, the QoS resource to be used for the end of the service is released. The QoS resource requirements of each service may be pre-configured. The QoS of the UE may be provided by the operator for the UE. The fixed QoS bearer resource service, the bearer channel bearer QoS includes the total service bearer channel established by the UE and the GW, and the bearer QoS of the bearer channel may be temporary, and the bearer QoS of the bearer channel includes QoS on the GW side and QoS on the UE side; In the case of QoS, the UE may be notified in real time through the bearer update mechanism of the 3rd Generation Partnership Project (3GPP) to ensure that the QoS of the UE and the GW are consistent. The bearer QoS of the bearer channel of the UE and the GW is successfully established in time, and the successful bearer QoS may be derived from the QoS subscribed by the UE, and the QoS of the bearer may also be based on the QoS of the service. Count obtained, when it is detected that the UE accesses the security services to be, GW-side all services available QoS, and calculates to obtain the QoS of each service bearer QoS bearer channel.

At a certain moment, the service under the bearer may be determined; but at different times, the service may be randomly changed. Once the service change is detected, the bearer QoS of the bearer channel may be adjusted immediately to adapt to the change of the service, and the service change includes not only the UE. When a certain service is started, the UE also stops using certain services. When all services are completed, the bearer QoS of the bearer channel is restored to the original state, and all dynamically applied QoS resources are released. When detecting the UE to update the to-be-protected service, the QoS of all the to-be-protected services of the UE is obtained, and the bearer QoS of the bearer channel to be adjusted is calculated by using the QoS of all the to-be-protected services, and the bearer QoS to be adjusted is taken as the QoS to be adjusted.

Step 20: Compare the subscription QoS of the UE with the QoS to be adjusted to determine whether the subscription QoS of the UE can meet the QoS requirements of all the currently guaranteed services.

Step 30: When it is determined that the subscription QoS fails to meet the QoS requirements of all the currently guaranteed services, the QoS of the service bearer channel is updated to be the QoS to be adjusted.

After calculating the QoS of all the to-be-protected services that need to be carried, the calculated QoS is used as the QoS to be adjusted. When the QoS of the UE can carry the QoS requirements of all the to-be-guaranteed services, the QoS of the UE is signed. The priority of each parameter is higher than or equal to the QoS of all services to be guaranteed. In this case, the bearer QoS of the bearer channel is the subscription QoS of the UE, and the number of QoS updates is reduced. When the subscription QoS of the UE cannot carry all the services to be guaranteed. When the QoS is required, the QoS of the bearer channel is updated to be the QoS to be adjusted. Since the QoS to be adjusted is the optimal QoS parameter of all the services to be guaranteed, the QoS to be adjusted can meet the QoS requirements of all the services to be guaranteed. The mobile network-based QoS dynamic adjustment process according to the service behavior is as shown in FIG. 6. According to the embodiment, for example, the current UE's to-be-guaranteed service is a conversation-type video service, a real-time game service, and an e-mail download service, in these three items. After the service is established, the QoS of the bearer channel of the three services is successfully established. If the voice service of the service session type is added, the QoS requirements of the four services are obtained. The bearer channel bearer QoS that satisfies the four service requirements, that is, guarantees the service quality of the four services, and compares the calculated bearer channel QoS of the four services with the UE's subscription QoS, such as UE subscription The QoS can meet the requirements of the four types of services, and the bearer QoS of the bearer channel is restored as the subscription QoS of the UE. If not, the bearer QoS of the bearer channel of the three uplink services is updated to calculate the bearer of the four types of services. The channel carries QoS.

As shown in FIG. 7 , when the GW detects the access of the UE, the GW and the UE bearer channel are successfully established. If the GW detects that the service 1 starts, the GW needs to adjust the bearer QoS required for the to-be-protected service 1. The QoS of the bearer channel to be tuned for the service to be secured 1 is QoS1. If the QoS of the UE is not able to carry the QoS requirement of the service to be secured, the QoS of the GW is updated to bear the QoS1, and the bearer update mechanism is adopted by the 3GPP. The UE side is notified in real time. The QoS on both the UE side and the GW side remains the same. After detecting the start of the service 2, the bearer QoS required to be secured for the service 1 and the service 2 is calculated and the calculated result is taken as the QoS 2. If the QoS requirement of the UE to be secured is still not QoS, the QoS of the GW side is updated to be the bearer QoS2, and the UE is notified in real time by the bearer update mechanism, and the QoS of the UE side and the GW side are consistent. After the end of the service 1 is detected, the update of the to-be-adjusted bearer QoS is only guaranteed to ensure the service 2, and after the end of the service 2 is detected, the QoS of the user subscription is restored.

In this embodiment, by detecting whether the UE updates the to-be-guaranteed service, when detecting that the UE updates the to-be-protected service, the QoS of the service bearer channel to be adjusted is obtained according to the QoS of all the to-be-protected services of the UE, and the to-be-adjusted is to be adjusted. Carrying QoS as the QoS to be adjusted; comparing the QoS of the UE with the QoS to be adjusted to determine whether the QoS of the UE can meet the QoS requirements of all the services to be guaranteed; when the QoS of the subscription fails to meet the QoS requirements of all the services to be guaranteed When updating the service bearer channel QoS, the QoS to be adjusted. When the service update is detected, the QoS requirements of all services to be secured are dynamically calculated to meet the requirements of all services for bearer QoS. The QoS guarantee service is dynamically adjusted according to the service type, and the QoS guarantee service of all services is satisfied. .

Optionally, the second embodiment of the QoS guarantee method is provided on the basis of the first embodiment of the QoS guarantee method of the present invention. Referring to FIG. 4, in the second embodiment, the bearer QoS includes parameters of ARP and QCI. Step 10 includes:

Step 11: Detect whether the UE updates a service to be secured;

Step 12: When it is detected that the UE updates the to-be-protected service, the ARP attribute value with the highest priority in the QoS of the current to-be-protected service of the UE is selected as the preferred ARP value of the QoS to be adjusted; ARP, Allocation and Retention Priority) can be used to determine whether the corresponding service bearer can be established and updated successfully when the allocated bearer QoS resources are restricted, and whether the UE is required to update the to-be-guaranteed service, and the QoS guarantee of the to-be-guaranteed service is based on the service behavior detection. The detection behavior of the unit, when detecting that the UE updates the to-be-protected service, selects the ARP attribute value with the highest priority in the QoS of the current to-be-protected service of the UE as the preferred ARP value of the QoS to be adjusted, and the calculation formula is Priority ( ARP (1), ARP (2), ARP (3) ... ARP (n)), ARP parameters are mainly sent to the eNodeB, which is used by the eNodeB to determine whether the corresponding bearer can be successfully established. The ARP parameters include the following three conditions: First, the priority of the bearer establishment is successful when the QoS resources are tight. The smaller the ARP value is, the higher the priority is. In the case of QoS resources being tight, the bearer establishment with ARP 1 takes precedence over the ARP 2 The bearer is established. The second is the ARP preemption capability. Whether the QoS resources of other bearers can be preempted if the resources are insufficient. The third is the preemption capability of the ARP. If the QoS resources are insufficient, the QoS resources are insufficient. In this case, the bearer will not be triggered to be released to save QoS resources.

Step 13: Select a QCI attribute value with the highest priority among the QoS of all the to-be-protected services of the UE as the preferred QCI value of the QoS to be adjusted;

Step 14: Calculate a required bandwidth of the QoS to be adjusted according to the preferred QCI value.

Here, the QoS Class Identifier (QCI) is a unified identification method for the UE and the GW to transmit services. Different QCI services need to use different bearers, and each QCI corresponds to a set of parameters, corresponding to the QCI. The parameter may be pre-configured on each device, and select the QCI attribute value with the highest priority among the current QCIs of the UE to be guaranteed as the QCI value of the QoS to be adjusted, Priority (QCI(1), QCI(2), QCI (3)...QCI(n)) is the calculation formula. The value of the QCI attribute with the highest priority is determined. The smaller the value of the QCI is, the higher the priority is. The required bandwidth of the QoS to be adjusted is calculated according to the preferred value of the QCI.

In this embodiment, by detecting whether the UE updates the to-be-guaranteed service; when detecting that the UE updates the to-be-protected service, the ARP attribute value with the highest priority among the QoS of the current to-be-protected service of the UE is selected as the preferred ARP for the QoS to be adjusted. The value of the QCI attribute with the highest priority in the current QoS of the UE to be guaranteed is selected as the preferred QCI value of the QoS to be adjusted; and the required bandwidth of the QoS to be adjusted is calculated according to the preferred QCI value. The value of the QoS parameters to be adjusted is the highest priority among the QoS parameters of the service to be secured under the current bearer. Therefore, the QoS guarantee service of all the services to be guaranteed can be satisfied, and the user experience is improved.

Optionally, the third embodiment of the QoS guarantee method is provided on the basis of the second embodiment of the QoS guarantee method of the present invention. In the third embodiment, step 14 includes:

When the preferred QCI value is in the first preset interval, the sum of the MBRs of all currently to-be-guaranteed services is selected as the MBR of the QoS to be adjusted; and/or the sum of the GBRs of all currently to-be-guaranteed services is selected as the to-be-adjusted QoS. GBR;

When the highest priority QCI attribute value is the second preset interval, the APN-AMBR with the largest current service value is selected as the APN-AMBR of the QoS to be adjusted.

The Bearer is divided into a GBR bearer and a Non-GBR bearer. The GBR bearer guarantees the bit rate bearer, the Non-GBR bearer does not guarantee the bit rate bearer, and the service guarantee method guarantees the bit rate of the data stream by reserving QoS resources. When the GBR is not exceeded, the traffic that exceeds the GBR may be discarded. If the traffic exceeds the GBR, the traffic that exceeds the GBR but is less than the maximum bit rate (MBR) can pass. The QCI is 1 to 4. The identifier of the MBR is the bearer of the GBR, and the identifier of the QCI is 5 to 9 is the Non-GBR bearer. When the QCI attribute value of the highest priority is 1-4, the sum of the MBRs of all the services to be secured is selected as the MBR of the bearer. The sum of the GBRs of all the services to be secured is selected as the GBR of the QoS to be adjusted. When the value of the highest priority QCI is 5-9, the APN-AMBR with the largest current service is selected as the APN of the QoS to be adjusted. AMBR, APN-AMBR is the maximum bit rate rate of all non-GBR bearers aggregated by a UE in a network access technology (APN). The different scenarios are shown in Figure 5.

In this embodiment, when the preferred QCI value is in the first preset interval, the sum of the MBRs of all currently to-be-protected services is selected as the MBR of the QoS to be adjusted and/or the sum of the GBRs of all the currently-guaranteed services is selected. The GBR of the QoS to be adjusted is selected. When the value of the QCI attribute with the highest priority is the second preset interval, the APN-AMBR with the largest current service value is selected as the APN-AMBR of the QoS to be adjusted. Since the bandwidth conforms to the calculation method in the 3GPP protocol, the terminal is applicable to the UE_ONLY mode or the UE_NW mode, and the versatility is stronger.

Optionally, the fourth embodiment of the QoS guarantee method is provided on the basis of the first embodiment of the QoS guarantee method of the present invention. In the fourth embodiment, the QoS calculation of all current to-be-guaranteed services of the UE is obtained and obtained. The adjusted bearer QoS, and the bearer QoS to be adjusted as the to-be-adjusted QoS includes:

When the UE is detected to update the to-be-guaranteed service, the current mapping of all the to-be-guaranteed services is performed according to the QCI attribute value;

Determining whether the updated service to be secured is the same as the type of the service to be secured before the update, and when not the same, obtaining the bearer QoS of the service bearer channel to be adjusted according to the QoS of all the to-be-protected services of the UE, The bearer QoS to be adjusted is taken as the QoS to be adjusted.

Obtain and classify the guaranteed service according to the value of the QCI attribute of the service to be secured. For example, when the attribute value of the service QCI is the same, the service has similar requirements for data delay and packet loss rate, for example, the attribute value of the session type voice service QCI is the same. , can be classified into one type, the conversational video service is also classified into one category according to the attribute value of QCI; real-time games are classified into one category; mailbox business, FTP download, www business, etc. are classified into one class, etc., and the updated If the service to be secured is the same as the type of the service to be secured before the update, the QoS of the QoS to be adjusted is calculated by using the QoS of all the to-be-protected services of the UE.

In this embodiment, when it is detected that the UE updates the to-be-protected service, the current all the to-be-guaranteed services are classified and mapped according to the QCI attribute value; and the updated to-be-guaranteed service and the pre-updated to-be-guaranteed service are determined. If the QoS is not the same, the QoS of the bearer to be adjusted is determined according to the QoS of the current to-be-protected service of the UE, and the QoS to be adjusted is used as the QoS to be adjusted. Therefore, when the QoS guarantee service is dynamically adjusted according to the service type to meet the QoS guarantee service of all services, the number of times of adjusting the bearer QoS is reduced, thereby improving the user experience.

Optionally, the fifth embodiment of the QoS guarantee method is provided on the basis of the first embodiment of the QoS guarantee method of the present invention. In the fifth embodiment, the QoS guarantee method further includes:

When it is detected that all current to-be-guaranteed services are completed or when the subscribed QoS of the UE meets the QoS requirements of all currently-to-be-guaranteed services, the restored bearer channel QoS is the subscribed QoS of the UE.

When it is detected that all the services to be secured are completed, the QoS of the bearer channel is restored to be the subscription QoS of the UE, so that the UE provides the QoS of the service bearer channel according to the subscription QoS of the UE when the user accesses the service. When the subscription QoS of the UE meets the QoS requirements of all the to-be-protected services, the QoS of the recovery bearer channel is the subscription QoS of the UE, so as to reduce the occupation of the QoS resources of the bearer channel.

In this embodiment, the bearer channel QoS is restored as the subscription QoS of the UE when it is detected that all current to-be-guaranteed services are completed or when the subscribed QoS of the UE meets the QoS requirements of all currently to-be-guaranteed services. In addition, when the subsequent service is to be guaranteed, the service bearer channel is provided in time and the occupation of the QoS resources of the bearer channel can be effectively reduced.
