Data channel establishment method and communication device

Abstract

The invention discloses a data channel establishment method and communication equipment, which belong to the field of network communication. The method includes: the sending end sends a proposal message carrying the first proposed attribute row and the second proposed attribute row to the receiving end; receiving a response message, the response message is the receiving end according to the first proposed attribute row, the second proposed attribute row and the The data channel negotiation method supported by the receiving end is determined; the data channel is established with the receiving end according to the response message. The invention solves the problem that the two ends of the communication cannot negotiate to establish the data channel when at least one of the two ends of the communication supports two or more data channel negotiation modes at the same time. When at least one of the two ends supports two or more data channel negotiation methods, through the negotiation of the data channel negotiation methods at both ends, and on this basis, the data channel is established, so that the two ends can easily and efficiently establish the data channel , realizing the interconnection and intercommunication between different terminals and different networks.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a data channel establishment method and communication equipment. Background technique [0002] SCTP (Stream Control Transmission Protocol, Stream Control Transmission Protocol) is a reliable transport layer protocol defined by IETF (Internet Engineering Task Force, Internet Engineering Task Force), which provides stable and ordered data between two SCTP endpoints transfer service. An SCTP endpoint is the logical receiver or sender of an SCTP packet, and an SCTP association exists between two SCTP endpoints. There can be multiple SCTP streams under one SCTP association, and each SCTP stream has a unique stream identifier. Among them, the SCTP flow is a unidirectional logical channel established between two SCTP endpoints, and the data channel is a bidirectional logical channel including a pair of incoming and outgoing flows, and the pair of incoming and outgoing flows have t...
