Detailed Description

The present disclosure will be described below with reference to the accompanying drawings. It is to be noted that the following description is merely illustrative and exemplary in nature and is in no way intended to limit the disclosure, its application, or uses. Unless specifically stated otherwise, the relative arrangement of components and steps and numerical expressions and values set forth in the embodiments do not limit the scope of the present disclosure. Additionally, techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail but are intended to be part of the specification where appropriate.

The following embodiments of the present disclosure provide a control capability for scheduling a PCRF policy by presetting a service guarantee level and matching with a simplest open interface design, so as to quickly implement QoS guarantee of a self-supporting service.

The self-service services may include, but are not limited to, audio services, video services, data services, application services, control services, text services, and message services.

As shown in fig. 1, this embodiment may include the steps of:

s102, receiving a service guarantee application initiated by a self-service through an open gateway, wherein the guarantee application comprises a service ID, a service type and a terminal user number;

for example, when a certain user uses some self-service services, if the user wants to increase the downloading speed, the user initiates an application to a self-service provider through the internet, and at this time, the self-service provider submits a service guarantee application to the PCRF through the open gateway.

S104, the PCRF queries whether the service ID has the service guarantee authority or not in a user subscription database by using the service ID carried in the service guarantee request.

S106, if the service ID has the service guarantee authority, the service guarantee can be provided for the service ID, the service type carried in the service guarantee application is matched with the mapping relation between the service type and the guarantee grade stored in the user subscription database so as to match out the guarantee grade corresponding to the service type carried in the service guarantee application, and after the guarantee grade is matched out, the QoS characteristic value corresponding to the guarantee grade is found out.

S108, receiving a QoS characteristic value corresponding to the guarantee level returned by the user subscription database;

in particular, the QoS characteristic values may include, but are not limited to, the uplink and downlink bandwidths allocated for the traffic types, the duration of the allocations, and the priority of use of the wireless channel when network congestion is encountered.

S110, the QoS characteristic value is sent to the strategy and charging executive function device, so that the strategy and charging executive function device modifies the QoS of the corresponding IP flow according to the received QoS characteristic value.

In this embodiment, since the mapping relationship between the service type and the guarantee level is configured in the user subscription database in advance, when receiving a service guarantee application initiated by a self-owned service, in the case of judging that the service guarantee application has a guarantee authority, the guarantee level corresponding to the self-owned service used by the user is searched according to the stored mapping relationship, and the QoS feature value corresponding to the guarantee level is sent to the policy and charging execution function device, so that the policy and charging execution function device applies the QoS policy to a corresponding IP stream, and further, a corresponding QoS guarantee can be provided for the self-owned service used by the user.

Further, in step S110, the policy and charging enforcement function device queries the original QoS subscription information of the user using the self-service;

In addition, a mapping relationship between the service type and the security level needs to be stored in the subscriber subscription database in advance, so that the PCRF can find the security level corresponding to the service type carried in the service provisioning application according to the mapping relationship.

As shown in fig. 2, the following process may be included:

(1) referring to fig. 2, QoS level presetting is performed according to a service type:

according to the service type, the service security level is configured in an SPR (Subscription profile repository) in advance to map the service type and the security level, specifically, the security level may be determined according to an operator policy, and is usually a gold user, a silver user, or a bronze user, and the users at each level may be further subdivided, for example, may be generally determined as 8 levels for further expansion.

(2) Referring to the second step in fig. 2, the self-service initiates a QoS guarantee request:

the simplest open interface design:

the information provided by the self-service may include, but is not limited to: service ID, service type and end user MDN (Mobile Directory Number). For example, for an application with a video type service, a certain operator may have multiple video applications, and each application has its own ID for distinguishing the multiple applications.

(3) See- (c) -v in fig. 2, query and execution of the assurance level:

the PCRF firstly inquires whether the service has the guarantee authority through the service ID, if so, then inquires the guarantee grade corresponding to the service type carried in the guarantee request by using the mapping relation stored in the SPR, and executes a corresponding control strategy according to the guarantee grade, such as uplink and downlink bandwidth guarantee, guarantee time limit and the like, so as to provide corresponding resources for the terminal user. The guaranteed time limit may be, for example, 1 minute, 1 hour, or 1 day, and is selected by the user or specified by the application.

Furthermore, besides the service guarantee application of the self-service, the services such as modification, gating and revocation of the service guarantee can be realized through the deployed open gateway. The gating can only allow uplink or downlink traffic, the cancellation refers to stopping the service provisioning, and the modification refers to modifying parameters of the current service provisioning.

As shown in fig. 3, this embodiment may include the steps of:

the method comprises the following steps: and configuring in a user database SPR used by the PCRF, and distinguishing different guarantee grades according to different service types.

When the self-service business needs to apply for the temporary business guarantee, the self-service business can initiate an application request to the PCRF through the open gateway. Specifically, the method comprises the following steps:

s302, the self-service sends a service guarantee request to the open gateway, wherein the request comprises an application ID, a user identification MDN and a service type.

S304, the open gateway performs protocol adaptation, encapsulates the service provisioning Request into an AAR (authentication and authorization Request) message, and sends the AAR message to the PCRF.

S306, the PCRF sends a response AAA (authentication and authentication Answer) to the open gateway.

S308, the PCRF inquires whether the application ID has the service guarantee authority or not according to the application ID, and if the service guarantee authority exists, the SPR matches a service guarantee level corresponding to the service type according to the service type.

S310, the SPR returns the matched QoS feature value corresponding to the service provisioning level to the PCRF, where the QoS feature value may include, but is not limited to, an uplink and downlink bandwidth allocated to the service, an allocated duration, a priority used for a wireless channel when a network congestion occurs, and the like.

S312, the PCRF issues the QoS Policy, i.e., the QoS feature value, to the PCEF (Policy and Charging Enforcement Function).

S314, the PCEF checks the subscription information against the request, identifies the relevant IP flows, modifies the QoS thereof, performs QoS authorization, and feeds back QoS policy enforcement information to the PCRF.

Specifically, the PCEF may check the original QoS subscription information of the user using the self-service from the AAA according to the MDN of the user, compare the received QoS characteristic value with the QoS subscription information, determine the priority of the two, identify the IP flow of the user by using the MDN of the user if the priority corresponding to the received QoS characteristic value is higher (this function is the self-owned function of the PCEF), change the QoS information of the user in the IP flow (for example, adjust the priority, etc.), so that the user enjoys a high QoS guarantee (that is, QoS authorization), and if the priority corresponding to the QoS subscription information is higher, not change the QoS information in the IP flow of the user.

S316, PCRF returns RAR (Re-Authentication Request) message to open gateway, and informs user QoS modification success.

And S318, the open gateway returns a service application response to the self-service.

The examples of the open interface of the service provisioning application are shown in the following table:
