Abstract:
Provided are a communication method, device and system. The method comprises: a first network element receiving identification information of a terminal from a second network element, wherein the identification information comprises an identifier of the terminal or a group identifier of the terminal; the first network element acquiring, according to the identification information, type information of a service network corresponding to the identification information; and the first network element sending application programming interface (API) information of the first network element according to the type information. In the method, after receiving identification information of a terminal sent by a second network element, a first network element acquires type information of a service network corresponding to the identification information, and sends API information or the type information of the service network to the second network element according to the type information of the service network, so that the second network element can choose, according to the API information or the type information of the service network, an available API for invoking, thus avoiding an error in API invoking, ensuring the success rate of API invoking and improving the user experience.
