Description

Service subscription method, device, equipment, storage medium and program product Technical Field The present invention relates to the field of communications, and in particular, to a service subscription method, apparatus, device, storage medium, and program product. Background With the introduction of new call architecture, a service opening method based on service subscription and event subscription has been applied to the subscription of services of various AS (Application Server ) for new calls. When the service AS initiates a service call event subscription flow, the service AS acts AS a client to initiate a request to a VoNR + (Voice over New Radio,5G network target voice solution) capability network element, and the VoNR + capability network element updates data to a UDM (Unified DATA MANAGEMENT ), which completes the storage and update of subscription data. It can be seen that the call flow based on service subscription is a key flow for triggering new call service under the decoupling architecture. However, in the Service subscription flow, the VoNR + capability network element does not authenticate the operation authority of subscription data and the change of subscription data, so that the Service AS can modify the transparent data such AS appid (Service unique identifier), service-Indication (Service type identifier), user-data (User subscription information) and the like optionally through the subscription flow, once the data fail, the core network cannot be matched with legal Service resources, because when the call is triggered due to error data stored in the UDM, the VoNR + capability network element cannot find the corresponding Service AS, or call an error Service interface, and finally, the new call Service cannot be triggered normally, thereby affecting the operation stability of the Service. Disclosure of Invention The embodiment of the invention aims to provide a service subscription method, a device, equipment, a storage medium and a program product, wherein VoNR + capacity network elements authenticate the operation authority and content of subscription data in a service subscription flow, avoid illegal operation and reduce the risk of tampering and service operation of the subscription data. In order to achieve the above objective, an embodiment of the present invention provides a service subscription method, applied to a VoNR + capability network element, where the method includes: receiving a subscription request of a service call event sent by an application server, wherein the subscription request carries a service identifier and a PSI parameter; performing authority authentication on the application server based on a preset first mapping relation between the application server and the service identifier; When authority authentication passes, performing content authentication on the PSI parameters based on a second mapping relation between the PSI parameters and the service identifiers; And when the content authentication is passed, initiating a subscription event corresponding to the subscription request to the UDM network element. As an improvement of the above scheme, the subscription request is a new subscription request, a data change request or an unsubscribe request. As an improvement of the above solution, when the content authentication passes, the method further includes: and recording the service identification. As an improvement of the above solution, when the service call event is a non-DC service, the subscription request further carries call event information. As an improvement of the above solution, when the content authentication passes, the method further includes: and recording the corresponding relation between the service identification and the call event information. As an improvement of the above solution, when the subscription request is a data change request, the subscription event is a subscription data update event, and after responding to the subscription data update event, the UDM network element sends the changed subscription data to other VoNR + capable network elements subscribed to the same service call event in the resource pool according to a preset synchronization mechanism, so that other VoNR + capable network elements update the subscription data. As an improvement of the above solution, when the subscription request is a unsubscribe request, the subscription event is an unsubscribe event, and after responding to the unsubscribe event, the UDM network element sends a subscription data deletion notification to other VoNR + capable network elements subscribed to the same service call event in the resource pool according to a preset synchronization mechanism, so that the other VoNR + capable network elements delete the subscription data. In order to achieve the above objective, an embodiment of the present invention further provides a service subscription apparatus, which is applied to a VoNR + capability network element, where the apparatus
