The present document is part of a TS-family covering the 3rd Generation Partnership Project: Technical Specification Group Services and System Aspects; Telecommunication management, as identified below:

• TS 32.351: "Communication Surveillance (CS) Integration Reference Point (IRP); Requirements";
• TS 32.352: "Communication Surveillance (CS) Integration Reference Point (IRP); Information Service (IS)";
• TS 32.356: "Communication Surveillance (CS) Integration Reference Point (IRP); Solution Set (SS) defintions".

The present document is part of a TS-family defining the Telecommunication Management (TM) of 3G systems. The TM principles are described in TS 32.101. The TM architecture is described in TS 32.102. The other specifications define the interface (Itf-N) between the managing system (manager), which is in general the Network Manager (NM) and the managed system (agent), which is either an Element Manager (EM) or the managed NE itself. The Itf-N is composed of a number of Integration Reference Points (IRPs) defining the information in the agent that is visible for the manager, the operations that the manager may perform on this information and the notifications that are sent from the agent to the manager. Communication Surveillance IRP (CSIRP) is one of these IRPs with special function. To ensure the availability and reliability of the management, an automatic surveillance of the communication between NM and the managed system are required. CSIRP is defined as a capability to achieve this goal.

The present document defines the Information Service (IS) part of the Communication Surveillance IRP (CSIRP). It describes the semantics of the information and the interactions visible across Itf-N in a protocol independent way. The information is specified by means of Information Object Classes (IOCs) and the interactions by means of operations and notifications. The present document does not specify the syntax (encoding) of the information.
