Description
Technical Field
The invention relates to the field of communication, in particular to a method and a device for establishing a channel between heterogeneous endpoints.
Background
The remote presentation system is the evolution of the traditional video conference system, has the capabilities which are not possessed by the traditional video conference, is more clear and vivid, realizes eye-to-eye communication, has better experience and the like, and also has great change in system realization. This results in that the interworking between the conventional video conference heterogeneous systems is not suitable for the remote presentation system.
At present, the main standards of IP network communication in the world are H.323 and SIP, both of which propose complete solutions for IP telephone system signaling, and H.323 adopts a traditional telephone signaling mode comprising a series of protocols; whereas SIP uses the internet protocol for reference and employs a text-based protocol.
When the H.323 protocol is adopted, multimedia products and applications of different manufacturers can be operated mutually, and a user does not need to consider the compatibility problem; and the SIP protocol is more flexible to apply and has strong expandability, and the two protocols have respective emphasis.
The structural differences of the system are as follows:
in the h.323 system, the terminal mainly provides data for media communication, the function is relatively simple, and the realization of functions such as call control, media transmission control and the like is mainly completed by the gatekeeper, so that the h.323 system embodies a centralized and hierarchical control mode.
The SIP adopts a message mechanism of a Client/Server structure, and the control of the call is realized by encapsulating control information into a header field of a message and transmitting the message. The terminals of the SIP system are thus intelligent, providing not only data but also call control information, and various other servers for locating, forwarding or receiving messages. Thus, SIP pushes the complexity of network devices to network terminal devices, so that it is more suitable to construct an intelligent SIP system for user terminals to embody a distributed control mode.
In contrast, the h.323 centralized control mode is convenient for management, such as charging management, bandwidth management, call management, etc., to be implemented under centralized control, and the limitation is that it is easy to cause a bottleneck. While the SIP distribution mode is not easy to cause bottleneck, but the management functions are relatively complex to implement.
The existing remote presentation endpoints have two types, namely H.323-based and SIP-based, and a better solution for the problem of how to enable the two heterogeneous remote presentation endpoints to intercommunicate does not exist at present.
An effective solution is not proposed yet for the problem in the related art that a channel for transmitting a media stream cannot be established between endpoints of different structures.

In this embodiment, an endpoint information interaction processing method is provided, and fig. 8 is a flowchart of an endpoint information interaction processing method according to an embodiment of the present invention, where as shown in fig. 8, the flowchart includes the following steps:
step S801, the terminal A sends H.225.0 call establishment CLUE control capability to the gateway;
step S802, the endpoint B sends SIP invite SIP to the gateway;
step S803, a CLUE call is established between the endpoint A and the endpoint B;
step S804, H.245 capability negotiates data application capability;
step S805, H.245 opens a logic channel;
step S806, establishing a terminal A and a terminal BCLUE data channel;
step S807, CLUE message (capture/encode);
step S808, CLUE message (capture/encode);
step S809, H.245 capability negotiates CLUE coding correlation;
step S810, SIP invites CLUE control code;
step S811, H.245 opens a logic channel;
step S812, establishing a media transmission channel between the endpoint a and the endpoint B;
in step S813, media is transmitted between endpoint a and endpoint B.
The two heterogeneous endpoints exchange CLUE features through the gateway to ensure that both endpoints support CLUE and establish CLUE calls through the gateway. The remote presentation endpoint A based on the H.323 adopts H.225.0 calling information, carries CLUE control capability as CLUE characteristic parameters and represents support of CLUE; the SIP-based remote presentation endpoint B adopts SIP invitation information, carries CLUE media characteristic labels as CLUE characteristic parameters and represents support of CLUE.
Two heterogeneous endpoints establish a CLUE channel through the gateway for performing CLUE signaling. The H.323-based remote presentation endpoint A carries data application capability information which is used for carrying relevant parameters for establishing a CLUE channel; SIP-based telepresence endpoint B already carries the relevant parameters for establishing the CLUE tunnel in the call signaling. After receiving the parameters at the two ends, the gateway establishes a point-to-point CLUE channel directly at the two ends, or establishes CLUE channels with the two endpoints respectively.
Two heterogeneous endpoints negotiate CLUE capability through the gateway and create a media transmission channel for media stream transmission. The negotiation of CLUE capability through the gateway is as follows: the remote presentation endpoint A based on H.323 sends and receives CLUE messages through a CLUE channel, carries negotiation information such as version, capture and/or coding and the like, and carries CLUE related coding parameters with the gateway through H.245 capability exchange messages; the remote presentation endpoint B based on the SIP sends and receives CLUE messages through a CLUE channel, carries negotiation information such as version, capture and/or coding and the like, and carries CLUE control coding parameters with messages such as SIP invitation and the like between gateways.
Wherein, establishing media stream transmission creates a media transmission channel: h.323 based telepresence endpoint a sends an h.245 open logical channel message according to the clee capability exchange result. SIP-based remote presentation endpoint B carries messages such as ports of the media streaming channel in messages such as SIP invite. The gateway establishes media transmission channels with the two endpoints respectively based on the media transmission channel parameters (IP address, port, media identifier to be transmitted, media attribute, etc.) of the two heterogeneous endpoints, and then performs actual media stream transmission. The gateway can encode and decode the media stream for the second time, or only transmit without any modification. Or the gateway sends the media transmission channel parameter of the endpoint B to the endpoint A, sends the endpoint A to the endpoint B, and directly transmits the actual media stream between the endpoint A and the endpoint B, wherein the actual media stream does not pass through the gateway.
