AI Technical Summary

Technical Problem

In existing technologies, users with different terminal capabilities access the same functional network element pool without distinction. This results in the need to upgrade the hardware of all functional network element devices in the existing network when deploying new services, which increases the difficulty of deployment and wastes resources, and may also lead to a decline in user experience.

Method used

By using a terminal capability-based functional network element discovery method, access and mobility management functional network elements and session management functional network elements are used to obtain the capability information of user terminals, and target functional network elements are determined according to the terminal capabilities, reducing the need for hardware upgrades and requiring only software modifications to a small number of devices.

Benefits of technology

It reduces the difficulty of network equipment transformation, improves the efficiency of terminal discovery function network elements, reduces system deployment and maintenance costs, enhances user experience, and supports the deployment of diverse new media services.

Abstract

The present disclosure provides a terminal capability-based function network element discovery method, and relates to the field of communication, which comprises the following steps: receiving an information request for a target function network element initiated by a user terminal; obtaining terminal capability of the user terminal; forwarding the information request and the terminal capability to a session management function network element; and receiving information of the target function network element determined by the session management function network element according to the terminal capability and forwarding the information to the user terminal. The method of the present disclosure does not need to massively upgrade all network devices in the existing network, but only needs to upgrade the capability of a small number of devices according to business requirements, greatly reducing the difficulty of upgrading network devices, and effectively improving the efficiency of terminal discovery function network elements and user experience.
