21、HW ID IMSI LCS LLP LMU MLC MMI MS MSC NE NM NSS O - Operability: whether or not the resource is physically installed and working. The present document defines the following three state management attributes to represent the management state of a managed entity: - Administrative state; - Operational
22、state; - Availability status (this provides additional information for understanding the operational state values). 7.1.1.3.1 Administrative State Administrative states of the managed entity can be controlled only by the SMLC. The locked state of a managed entity means that the SMLC has terminated a
23、ll requests to the resource that is represented by the managed entity. No new requests are initiated to this resource. The shutting down state means that no new requests are initiated to this resource. The on-going requests are completed. The unlocked state means that new requests are allowed to the
24、 resource represented by the managed entity. 7. I. 1.3.2 Operational State CCITT X.73 1 gives the following definitions for the values of the operational state attribute: - - disabled: the resource is totally inoperable and unable to provide service to the user(s); enabled: the resource is partially
25、 or fully operable and available for use. In the present document the value disabled represents the following conditions that the resources could have: - - power is turned off; - failure has occurred; - hardware or software is not installed; radio parameters have not yet been set by elementary proce
26、dures (7.1.2), therefore, the resource is off-line. ETSI 3GPP TS 52.071 version 4.0.0 Release 4 17 ETSI TS 152 071 V4.0.0 (2001-03) 7. I. 1.3.3 Availability Status The availability status elaborates the operational state attribute. State change is only reported when the operational state changes, no
27、t when availability status changes. Availability status is only sent as information along with the state change indication. In the present document the following values are used (availability status is a set value): In test: The resource is undergoing a test procedure. The operational state may be d
28、isabled or enabled, depending on the level of intrusion of the test. Failed: The resource has an internal fault that prevents it from operating. The operational state is disabled. Power off: The resource requires power to be applied and is not powered on. The operational state is disabled. Off line:
29、 The resource requires some manual andor automatic operation(s) to be performed to make it available for use. The operational state is disabled. Dependency: The resource cannot operate because some other resource on which it depends is unavailable. The operational state is disabled. Degraded: The se
30、rvice available from the resource is degraded in some respect, such as in speed or operating capacity. The operational state is enabled. Not installed: The hardware or the software associated with the managed entity has not been installed at the site. Operational state is disabled. Figure 3 illustra
31、tes the operational state and availability status behaviour of managed entities. The initial value of the administrative state is locked.

35、e to the LMU consist of bringing LMU equipment and software into (or taking them out of) service, initiation of tests at the LMU, collection of test results made at the LMU, reporting and clearing of any LMU faults, and reporting of any LMU external alarms. Bringing into service of equipment at the
36、LMU will consist of manual operations, including powering on, and performing local testing where relevant at the LMU, followed by an indication to the SMLC of the LMU equipment availability. It is then an SMLC function to ensure that relevant data on the existence of the equipment is resident at the
37、 LMU, and to activate (bring into service) the new equipment. 7.1.2.1 Definition of the Procedures All the procedures covered in the present document are based on formatted O Pertaining to a failure, there shall be a report for its start and another for its end. A failure causing change of operation
38、al state shall generate two event reports: State Changed Event Report and Failure Event Report. No ACK or NACK is returned to the LMU. SMLC Failure Event Report LMU 7.1.2.5.2 Stop Sending Event Reports (See ITU Recommendation M.3400 101 Fault Management/Alarm Surveillance/Alarm Reporting/Inhibit Ala
39、rm Reporting). This inhibition of sending of event reports shall be used by the SMLC to prevent a flood of event reports which are of no benefit to the SMLC. One example of this occurs at an LMU restart following a power failure. The operational capability of the LMU hardware is unlikely to be diffe
40、rent from what it was before the failure, and a flood of reports, each stating that a piece of hardware is operating, will delay the software download. Another example concerns the case of a frequently occurring transient fault. SMLC Stop Sending Events Reports LMU r ACWNACK F Meaning of ACK message
41、: Sending of specified Event Report has been stopped. Message specific NACK causes (see Subclause A. 1.2.4.24): None. 7.1.2.5.3 Restart Sending Event Reports (See ITU Recommendation M.3400 101 Fault Management/Alarm Surveillance/Alarm Reporting/Allow Alarm Reporting). When the LMU is back in normal
42、operation or if it is of interest to check whether the LMU still generates a flood of Event Reports, a Restart Sending Event Reports shall be sent. SMLC Restart Sending Events Reports LMU r ACWNACK - Meaning of ACK message: Sending of specified Event Report has been restarted. Message specific NACK
43、causes (see Subclause A. 1.2.4.24): None. ETSI 3GPP TS 52.071 version 4.0.0 Release 4 24 ETSI TS 152 071 V4.0.0 (2001-03) 7.1.2.5.4 Report Outstanding Alarms (See ITU Recommendation M.3400 101 Fault Management/Alarm Surveillance/Alarm Reporting/Request Alarm History). This message shall be used by t
44、he SMLC to ask the LMU to report all outstanding alarms related to the managed entity instance indicated in the message. The LMU shall report alarms by sending a series of Failure Event Report messages for all outstanding alarms. Only those alarms previously reported and still outstanding shall be r
45、e-reported through this procedure. Any new alarms not yet reported but about to be reported shall be excluded and they shall be reported through a separate Failure Event Report procedure spontaneously initiated by the LMU itself. If there is no outstanding alarm, the LMU shall reply with a NACK with
46、 that cause indicated. SMLC LMU Report Outstanding Alarms ACWNACK b 4 Meaning of ACK message: Sending of Failure Event Report will start. Message specific NACK causes (see Subclause A.1.2.4.24): 40,41,42. 7.1.2.6 Equipment Management Procedures Equipment Management Procedures provide the capability
47、to control equipment during maintenance. 7.1.2.6.1 Change-over (See ITU Recommendation M.3400 101 Configuration Management/Status and ControVStatus and Control of NEs). This message shall be sent to change over between active and standby units of equipment. The action may be performed on any address
48、able functional managed entity and manufacturer-dependent HW units. Which type of HW unit to address and how to identiSl certain units of this type of HW are manufacturer-dependent. SMLC LMU Change-over r ACWNACK Meaning of ACK message: The specified change-over operation has been performed. Message
49、 specific NACK causes (see Subclause A.1.2.4.24): 25, 26, 30, 35. 7.1.2.6.2 Opstart (See ITU Recommendation M.3400 101 Configuration Management/Status and Control/NE Status and Control). This message shall be sent by the SMLC to tell the LMU to attempt to operate the identified managed entity putting it to an initial normal operational state (i.e., enabled, see Subclause 7.1.1.3.2). This message does not affect the managed entitys administrative state if there exists a value explicitly assigned by the SMLC. If there is yet no administrative state
