NG-RAN标识

NG-RAN identifiers

1.Principle of handling Application Protocol Identities

处理申请协议标识的原则
An Application Protocol Identity (AP ID) is allocated when a new UE-associated logical connection is created in either an NG-RAN node or an AMF. An AP ID shall uniquely identify a logical connection associated to a UE over the NG interface or Xn interface within a node (NG-RAN node or AMF) or over the F1 interface or over the E1 interface. Upon receipt of a message that has a new AP ID from the sending node, the receiving node shall store the AP ID of the sending node for the duration of the logical connection. The receiving node shall assign the AP ID to be used to identify the logical connection associated to the UE and include it as well as the previously received new AP ID from the sending node, in the first returned message to the sending node. In all subsequent messages to and from sending node, both AP IDs of sending node and receiving node shall be included.

当一个与用户设备相关的逻辑连接在NG-RAN或者AMF（5GC）中创建时，应用协议标识被分配。AP ID唯一标定一个关联UE和NG-RAN或者AMF（通过NG，Xn，F1和E1）的逻辑连接。一旦接收到发送节点有新的AP ID的消息，接收节点会保存发送节点的AP ID，为了继续两者之间的逻辑连接。接收节点将会分配AP ID去标定与UE关联的逻辑连接，并在返回发送节点的第一个消息中包含它以及先前从发送节点接收到的AP ID标识。在发往和来自发送节点的消息，都包含发送节点和接收节点的AP ID。

RAN UE NGAP ID (RAN to AMF)
A RAN UE NGAP ID shall be allocated so as to uniquely identify the UE over the NG interface within an gNB. When an AMF receives an RAN UE NGAP ID it shall store it for the duration of the UE-associated logical NG-connection for this UE. Once known to an AMF this is included in all UE associated NGAP signalling.
