QoS on both sides of the UE side and the GW side is kept consistent. And calculating the required bearing QoS of the service 1 and the service 2 to be guaranteed until the start of the service 2 is detected, and taking the calculated result as the QoS 2. If the signed QoS of the UE cannot bear the QoS requirements of the current services 1 and 2 to be guaranteed, updating the GW side bearing QoS to bearing QoS2, notifying the UE side in real time through a bearing updating mechanism, keeping the QoS on the UE side and the QoS on the GW side consistent, calculating and updating the bearing QoS to be adjusted to only guarantee the service 2 if the service 1 is detected to be finished, and recovering the QoS signed by the user until the service 2 is detected to be finished.

The invention provides a QoS guarantee method based on a mobile network, in a first embodiment of the QoS guarantee method based on the mobile network, referring to fig. 3, the QoS guarantee system comprises UE and GW, a service bearing channel QoS is established between the UE and the GW, the QoS of the UE and the QoS of the GW are kept consistent, the QoS guarantee method based on the mobile network comprises the following steps:
step S10, detecting whether the UE updates the service to be guaranteed, when detecting that the UE updates the service to be guaranteed, acquiring the bearing QoS to be adjusted of a service bearing channel according to the QoS of all the services to be guaranteed currently of the UE, and taking the bearing QoS to be adjusted as the QoS to be adjusted;
the UE is a UE, the GW is a gateway, the QoS is a fixed QoS guarantee service, where the QoS includes QoS of services, QoS signed by the UE, bearer QoS of bearer channels, and the like, when the QoS of a service is a service, a bearer QoS resource is to be applied for the service, and when the service is ended, a bearer QoS resource applied by the ended service is to be released, the bearer QoS resource requirement of each service may be pre-configured, the QoS signed by the UE is a fixed QoS bearer resource service provided by an operator for the UE, the bearer QoS of bearer channels is a total service bearer channel established by the UE and the GW, the bearer QoS of bearer channels may be temporary, the bearer QoS of bearer channels includes QoS of the GW and QoS of the UE, and when the QoS of the GW is updated, the UE is notified in real time through a bearer update mechanism of the third Generation Partnership Project 3GPP (the 3rd Generation Partnership Project) to ensure that the QoS of the UE and the GW is consistent, when the UE is detected to be accessed to the service to be guaranteed, namely the bearing channel of the UE and the GW is successfully established in time, the successfully established bearing QoS can be derived from the QoS signed by the UE, the bearing QoS can also be obtained according to the QoS calculation of the service, and when the UE side is detected to be accessed to the service to be guaranteed, the GW side can obtain the QoS of each service and calculate the QoS of each service so as to obtain the bearing channel bearing QoS.
At a certain determined moment, the service under bearer is determined, but at different moments, the service can be randomly changed, once the change of the service is detected, the bearer QoS of the bearer channel needs to be immediately adjusted to adapt to the change of the service, the change of the service includes not only that the UE starts to use a certain service, but also that the UE user stops using a certain service, and when all services are finished, the bearer QoS of the bearer channel needs to be restored to an original state, and all dynamically applied QoS resources are released. When the UE is detected to update the services to be guaranteed, the QoS of all the services to be guaranteed of the UE at present is obtained, the QoS of the bearer channel to be adjusted is calculated according to the QoS of all the services to be guaranteed at present, and the QoS of the bearer to be adjusted is used as the QoS to be adjusted.
Step S20, 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 QoS requirements for bearing all current services to be guaranteed;
step S30, when the signed QoS is not satisfied, the QoS of the service bearer is updated to the QoS to be adjusted.
After calculating the QoS of all the services to be guaranteed which need to be borne currently, taking the QoS obtained by calculation as the QoS to be adjusted, when the signed QoS of the UE can bear the QoS requirement of all the services to be guaranteed currently, namely the priority of each parameter of the signed QoS of the UE is higher than or equal to the QoS of each service to be guaranteed, restoring the bearing channel bearing QoS as the signed QoS of the UE at the moment, reducing the updating times of the QoS, and when the signed QoS of the UE can not bear the QoS requirement of all the services to be guaranteed currently, updating the bearing channel bearing QoS as the QoS to be adjusted. A dynamic adjustment process of QoS based on mobile network according to service behavior is shown in fig. 6, and is described in detail with specific embodiments, for example, the current service to be guaranteed of UE is a session-type video service, a real-time game service, and a mailbox download service, after the three services are established, bearer QoS of the three services is successfully established, for example, if a session-type voice service of the service to be guaranteed is added, in order to guarantee fixed QoS requirements of the four services, requirements of the four services for QoS parameters are obtained, bearer QoS of the bearer channel capable of meeting the four service requirements, that is, guaranteeing the service quality of the four services, is obtained by calculation, and then the computed bearer QoS of the bearer channel of the four services is compared with the subscribed QoS of the UE, and if the subscribed QoS of the UE can meet the requirements of the four services, the bearer channel bearer QoS is restored to the subscribed QoS of the UE, if not met, and updating the bearing channel bearing QoS of the three-upper class service into the calculated bearing channel bearing QoS of the four classes service.
As shown in fig. 7, when the GW detects that the user terminal is accessed, the GW and the UE bearer channel are successfully established, if the GW detects that the service 1 starts, the GW calculates the bearer QoS to be adjusted of the bearer channel required by the service 1 to be guaranteed, and sets the calculated bearer QoS to be adjusted of the bearer channel required by the service 1 to be guaranteed to be the bearer QoS1, and when the subscribed QoS of the UE cannot bear the QoS of the current service 1 to be guaranteed, the GW side bearer QoS is updated to be the bearer QoS1, and then the UE side is notified in real time through a bearer update mechanism of the 3 GPP. QoS on both sides of the UE side and the GW side is kept consistent. And calculating the required bearing QoS of the service 1 and the service 2 to be guaranteed until the start of the service 2 is detected, and taking the calculated result as the QoS 2. If the signed QoS of the UE cannot bear the QoS requirements of the current services 1 and 2 to be guaranteed, updating the GW side bearing QoS to bearing QoS2, notifying the UE side in real time through a bearing updating mechanism, keeping the QoS on the UE side and the QoS on the GW side consistent, calculating and updating the bearing QoS to be adjusted to only guarantee the service 2 if the service 1 is detected to be finished, and recovering the QoS signed by the user until the service 2 is detected to be finished.
In this embodiment, by detecting whether the UE updates the service to be guaranteed, when it is detected that the UE updates the service to be guaranteed, the QoS of the bearer to be adjusted of the service bearer channel is obtained according to the QoS of all the services to be guaranteed currently by the UE, and the QoS of the bearer to be adjusted is used as the QoS of the bearer to be adjusted; comparing the signed QoS of the UE with the QoS to be adjusted to determine whether the signed QoS of the UE can meet the QoS requirement for bearing all current services to be guaranteed; and when the signed QoS is not met, updating the QoS of the service bearer channel to the QoS to be adjusted. When the update of the service to be guaranteed is detected, the QoS requirement of each service on the bearing QoS is dynamically calculated according to the QoS requirements of all the current services to be guaranteed, so that the technical problem that the QoS guarantee service cannot be dynamically adjusted according to the service type to meet the QoS guarantee service of all the services in the prior art is solved.
