Fig. 3 is a schematic diagram of another embodiment of a method for providing a value added service before a call according to the present disclosure. Preferably, this embodiment can be executed by the pre-call value added service providing system of the present disclosure. The embodiment of fig. 3 is a value added service flow based on the pre-call state in the case that the subscriber terminal dials the target terminal. The method may comprise steps 31-37, wherein:

step 31, the subscriber terminal (for example, a merchant terminal or an enterprise terminal) opens the value added service before the call, and presents the value added service to the called terminal.

And step 32, the service platform sends the subscription data of the signed clients such as the enterprise client and the like to the voice network. When applied to an enterprise customer, the service platform may mark a plurality of subscriber terminal identifications (e.g., telephone numbers) designated by the enterprise as service provisioning states.

In step 33, the contracted client (e.g., an enterprise client) configures the content to be displayed before the call in advance, and can configure the cards with videos, pictures or mixed graphics and texts.

In some embodiments of the present disclosure, the method for providing a value added service before a call of the present disclosure may further include: the service platform verifies the content of the preset rich media message to be displayed before the call, and adds a content authentication identifier to the verified content of the rich media message.
