Method for obtaining device information of user terminals and communication service function entity
First Claim
1. A method for obtaining device information of user'"'"'s terminals in a communication system, comprising a communication service function entity performing:
- obtaining device information of a terminal of a target user, wherein the device information comprises at least a device display-name and ongoing session state information of the terminal of the target user, and the device display-name, which is defined for the user terminal by the target user;
associating the obtained device information with a target user ID and storing the device information as target user device information;
obtaining the ongoing session state information when a state of the on-going session joined by the target user terminal is changed;
associating the ongoing session state information with the target user ID and storing the ongoing session state information in the device information of the target user terminal;
in response to a device information obtaining request, sending the device information of the target user terminal to a requesting terminal according to the target user ID which is carried within the device information obtaining request, wherein the device information obtaining request is authorized according to at least one of;
a presence information authorization rule and notification filtering policy of the target user, or according to a local subscription notification and authorization policy.

Abstract
A method for obtaining device information of user terminals and a communication service function thereof are disclosed to enable a user to obtain terminal device information. The method for obtaining device information of user terminals in a communication system includes that a communication service function sends device information of a target user to a requesting terminal according to the target user ID carried in a device information obtaining request or a device information publish service setting. The communication service function includes: a receiving unit, adapted to receive a device information obtaining request or a device information publish service setting; a sending unit, adapted to send the stored device information of the target user to the requesting terminal according to the target user ID carried in the device information obtaining request or device information publish service setting.
