Method, apparatus and system for providing caller identification

摘要

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.

1. A method for providing caller identification (ID), implemented by a caller device having a phone number, comprising:
creating a portrait file to be used as a caller ID representing the caller device; generating a distribution policy corresponding to the portrait file; sending the portrait file to a portrait distribution system (PDS) on a server via an IP network; and sending the distribution policy to a policy control system (PCS) on the server via the IP network, to cause the PCS to perform a selective distribution process including:
selecting a callee device to be notified of the portrait file, by using the distribution policy;generating a notification based on the portrait file; andsending 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; wherein:
the downloading of the portrait file from the PDS by the callee device is before the caller device initiates a call to the callee device; andthe downloading of the portrait file from the PDS by the callee device and the calling of the callee device by the caller device are not simultaneous or synchronized; wherein the distribution policy corresponding to the portrait file includes: a phone number of a contact, wherein the contact is authorized by the caller device to download the portrait file from the PDS; and wherein the selective distribution process performed by PCS includes: before selecting the callee device to be notified of the portrait file, obtaining an address book uploaded from a device corresponding to the phone number of the contact; and wherein the selecting of the callee device to be notified of the portrait file includes:
looking up, in the address book, the phone number of the caller device;when the address book includes the phone number of the caller device, determining the device to be the callee device to be notified of the portrait file; andwhen the address book does not include the phone number of the caller device, determining the device not to be the callee device to be notified of the portrait file.
