Abstract: Various embodiments provide methods, apparatus, and systems for providing caller ID. In an exemplary method implemented on a caller device, a portrait file to be used as a caller ID is created, and sent to a portrait distribution system (PDS) on a server via an IP network. A distribution policy corresponding to the portrait file is generated, and sent to a policy control system (PCS) on the server via the IP network, to cause the PCS to perform a selective distribution process. The selective distribution process includes selecting a callee device by using the distribution policy, generating a notification, and sending the notification to the callee device, such that the callee device downloads the portrait file from the PDS via the IP network according to the notification and executes the portrait file as the caller ID when the caller device calls the callee device.
