Method and device for facilitating connectivity check between terminal device and media gateway
First Claim
1. A method implemented in a session controller for facilitating a connectivity check between a terminal device and a media gateway in a communication network, comprising:
- receiving, via a web gateway associated with said terminal device, a request for establishing a real-time communication call and an indication for indicating a capability of said terminal device for early reception of a connectivity parameter of said media gateway to be used in said connectivity;
requesting, said media gateway in a H.248 ADD message to add two terminations, including both a terminal device side termination and a core side termination;
receiving a reply from said media gateway in a H.248 ADD Reply message including said connectivity parameter, thereby obtaining said connectivity parameter from said media gateway, wherein said connectivity parameter includes Interactive Connectivity Establishment (ICE) attributes which are exchanged between said terminal device and said media gateway during ICE negotiation; and
in response to said connectivity parameter being obtained, sending said connectivity parameter via said web gateway towards said terminal device within a time limit, wherein the connectivity parameter received after the time limit is ignored by the terminal device.

Abstract
Embodiments of the present disclosure relate to a method and device for facilitating a connectivity check between a terminal device and a media gateway. In example embodiments, the session controller receives, via a web gateway associated with said terminal device, a request for establishing a real-time communication call and an indication for indicating a capability of said terminal device for early reception of a connectivity parameter of said media gateway to be used in said connectivity check. The session controller obtains said connectivity parameter from said media gateway. Then, in response to said connectivity parameter being obtained, the session controller sends said connectivity parameter via said web gateway towards said terminal device within a time limit. In this way, said terminal device may initiate said connectivity check to said media gateway earlier, and thus a latency of call establishment may be reduced significantly.
