Problems solved by technology

[0007] The present invention proposes a method and system for establishing an MRCP control and bearer channel, as well as a media resource controller and a media resource processor, which can solve the problem that the MRCP control and communication between the MRFP and the resource engine cannot be established under a separate architecture because the MRFP does not support the SIP protocol. bearer channel problem

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific implementation methods and accompanying drawings.

[0029] The embodiment of the present invention can be applied to realize the operation of various resource services through the MRCP protocol under the separation framework, such as resources defined by various MRCP protocols such as ASR resources, TTS resources, DTMF identification resources, speaker identification resources, and recording resources. However, for the convenience of description, the following embodiments only use the operations of ASR and TTS resources as examples for illustration.

[0030] image 3 It is a logical architecture diagram of performing ASR / TTS service operations through the MRCP protocol in the embodiment of the present invention. like image 3As shown, the logical architecture diagram includes AS, M...

Abstract

The invention relates to the field of communication, and discloses a method for establishing a control and loadsupporting channel of a media resource control protocol (MRCP). The method comprises: according to a resource service request, a media resource controller establishes session initiative protocol (SIP) session with a resource engine and then carries out SIP negotiation; and the media resource controller transmits SIP negotiation information to a media resource processor, and the MRCP control and loadsupporting channel between the media resource processor and the resource engine is completely established. The method solves the problem of the prior art that the MRCP control and loadsupporting channel between the MRFP and the resource engine can not be established under the separation structure because the MRFP does not support the SIP protocol. In addition, the invention also discloses a system, a media resource controller and a media resource processor for establishing the MRCP control and loadsupporting channel.

Description

technical field [0001] The invention relates to the communication field, in particular to a technology for establishing MRCP control and bearer channels. Background technique [0002] Media Resource Control Protocol (Media Resource Control Protocol, MRCP) is an emerging standard, which is mainly used to control and operate media resources on a distributed architecture. MRCP is not an independent protocol, and must rely on the session management protocol to establish a media resource control protocol MRCP control session between the client and the server. For the convenience of interaction, MRCP selects Session Initiation Protocol (Session Initiation Protocol, SIP) as the basic session management protocol, through the interaction of SIP messages between the client and the server, the connection information required for MRCP message transmission is negotiated, wherein, MRCP The session parameters are described by the Session Description Protocol (Session Description Protocol,...
