Specifically, in this embodiment, the call request is an SIP message. The SIP URI (Uniform resource identifier) can be adopted to uniformly identify the wired resource and the wireless resource so as to analyze the call request and acquire the related information of the corresponding user, thereby improving the convenience of information acquisition. The standard format of a SIP URI is: SIP: and the user name @ domain is a port, wherein the user name represents a user name, the domain represents an SIP domain, and the port is a port number.
For wired resources, each wired resource can be identified according to a user number or an equipment name; for the radio resource, the identifier of the radio resource can be formed according to the mobile subscriber number and the domain to which the mobile subscriber number belongs. By extracting the identifier carried in the call request, the corresponding target user number can be obtained according to the identifier.
