Abstract

The invention provides a signaling message transmission method of an IUB interface and the IUB interface, wherein the signaling message transmission method of the IUB interface comprises the steps as follows: receiving signaling messages transmitted on each connection connected with the IUB interface via the IUB interface, wherein the signaling messages comprise connection identifiers of connections for transmitting the signaling messages, the IUB interface determining a corresponding target SCTP flow for each signaling message according to number of the SCTP flow contained in a SCTP link and the connection identifiers in each signaling message and transmitting the each signaling message to a base station via the corresponding target SCTP flow. By introducing multi-flow mechanism at the place of the IUB interface of the RNC in the invention, the IUB interface can be used for distributing the signal messages transmitted on different connections to different SCTP flows so as to transmit the signaling messages on different SCTP flows to relieve congesting condition at the side of the RNC and improve transmission efficiency of the signaling messages.

Description

technical field [0001] The invention relates to communication technology, in particular to an IUB interface signaling message transmission method and the IUB interface. Background technique [0002] In the Internet Protocol (IP) transmission mode, the IUB interface in the Radio Network Controller (RNC) is connected to the base station (NodeB), and is used to transmit signaling messages to the NodeB through the IUB interface . [0003] At present, the IUB interface maps the signaling messages from all connections to an SCTP stream in the multi-stream control transmission protocol (Stream Control Transmission Protocol, referred to as SCTP) link, and then sends all the signaling messages through the SCTP stream Send to NodeB. [0004] In practical applications, there are a large number of signaling messages that need to be transmitted from the IUB interface to the NodeB. Currently, only one SCTP stream is used to transmit signaling messages. Some signaling messages may be blo...
