步骤1.UE-1通过会话初始化协议(Session Initiation Protocol，SIP)重邀请(re-Invite)消息向UE-2发起建立应用DC的请求，在该消息的SDP提议(SDP offer)中额外新增了一个a行，举例如下：
m＝application 52718 UDP/DTLS/SCTP webrtc-datachannel
b＝AS:500
a＝max-message-size:1024
a＝dcmap:10 subprotocol＝"http"
a＝dcmap:7216 max-retr＝5；label＝"low loss"
a＝3gpp-qos-hint:loss＝0.01；latency＝100
a＝dcmap:7216 max-retr＝5；label＝"low loss"代表application DC Step 1. UE-1 initiates a request to establish an application DC to UE-2 through the Session Initiation Protocol (SIP) re-invite (re-Invite) message, and adds an additional SDP offer in the message. A line a, for example:
m＝application 52718 UDP/DTLS/SCTP webrtc-datachannel
b＝AS:500
a=max-message-size:1024
a＝dcmap:10 subprotocol="http"
a＝dcmap:7216 max-retr＝5; label="low loss"
a＝3gpp-qos-hint:loss＝0.01；latency＝100
a＝dcmap:7216 max-retr＝5; label="low loss" represents application DC
stream ID为7216。The stream ID is 7216.
其中，a行代表数据通道属性信息，具体如下：Among them, row a represents the data channel attribute information, as follows:
a＝max-message-size:1024代表该属数据通道的能够传递的消息的最大值为1024个字节；a=max-message-size:1024 means that the maximum message that can be transmitted by this data channel is 1024 bytes;
a＝dcmap:10subprotocol＝"http"代表该属通道的APP从本地DC Server，即UE-1的DC Server下载；a＝dcmap:10subprotocol＝"http" means that the APP of this channel is downloaded from the local DC Server, that is, the DC Server of UE-1;
若a＝dcmap:110subprotocol＝"http"代表该属通道的APP从对方DC Server，即UE-2的DC Server下载；If a＝dcmap:110subprotocol＝"http", it means the APP of this channel is downloaded from the other DC Server, that is, the DC Server of UE-2;
a行内10和110为stream ID，stream ID用于标识DC，通常0-999用于标识bootstrap DC，大于等于1000的用于标识application DC。10 and 110 in row a are stream IDs. The stream ID is used to identify the DC. Usually 0-999 is used to identify the bootstrap DC, and 1000 or more is used to identify the application DC.

步骤3.AS向DC Server-1发送application DC建立请求。Step 3. AS sends application DC establishment request to DC Server-1.
步骤4.DC Server-1向AS发送DC建立响应，该响应中包含该application DC的建立策略，例如UE-1与UE-2直接建立application DC或通过DC server建立DC。Step 4. DC Server-1 sends a DC establishment response to the AS.
