3.1 Definitions
For the purposes of the present document, the following terms and definitions apply.
CRNC Communication Context: The CRNC Communication Context contains the necessary information for the CRNC for communication with a specific UE. The CRNC Communication Context is identified by the CRNC Communication Context ID.
Elementary Procedure: The NBAP protocol consists of Elementary Procedures (EPs). An Elementary Procedure is a unit of interaction between the CRNC and the Node B.
An EP consists of an initiating message and possibly a response message.
Two kinds of EPs are used:
– Class 1: Elementary Procedures with response (success or failure).
– Class 2: Elementary Procedures without response.
For Class 1 EPs, the types of responses can be as follows:
Successful
– A signalling message explicitly indicates that the elementary procedure has been successfully completed with the receipt of the response.
Unsuccessful
– A signalling message explicitly indicates that the EP failed.
Class 2 EPs are considered always successful.
Node B Communication Context: The Node B Communication Context contains the necessary information for the Node B for communication with a specific UE. The Node B Communication Context is created by the Radio Link Setup procedure and deleted by the Radio Link Deletion procedure when deleting the last Radio Link within the Node B Communication Context. The Node B Communication Context is identified by the Node B Communication Context ID.
Prepared Reconfiguration: A Prepared Reconfiguration exists when the Synchronised Radio Link Reconfiguration Preparation procedure has been completed successfully. The Prepared Reconfiguration does not exist anymore only after either of the procedures Synchronised Radio Link Reconfiguration Commit or Synchronised Radio Link Reconfiguration Cancellation has been completed. In particular, the Prepared Reconfiguration still exists if the object (e.g. Radio Link) concerned by the Synchronised Radio Link Reconfiguration (e.g. in the case of an HS-DSCH Setup) is removed, but the Node B Communication Context still exists.
