6 LCS O&M Functions

12.713GPPLocation Services (LCS)Location services managementTS

The LCS management functions are grouped into the following five management areas: Performance Management, Fault Management, Configuration Management, Accounting Management and Security Management.

6.1 LMU Management

The description here is based on both Type A and Type B LMUs. O&M related messages will be transferred between the LMU and the SMLC in the same way as the TOA and RIT measurement messages, i.e. from LMU to BTS, BSC, (possibly) MSC and SMLC. It is viewed as a transparent path. The LCS O&M information is stored in the database of the SMLC.

NOTE: This clause covers LMU functions only. The SMLC will need to support these functions and may perform additional functions as well.

This clause contains requirements that are common to all LMUs. When certain characteristics of an LMU only apply to a specific type, these characteristics are indicated in later clauses as conditional on the type. (An example of a specific type of LMU is one that uses GPS to obtain absolute time and thus is able to derive its own position.) When the characteristics of an LMU are specific to the implementation, these characteristics are handled using manufacturer-specific messages or using the software download capability. (Examples of these kinds of data are initialisation data, GPS set-up commands and software files.)

NOTE: Only the necessary functions in ITU Recommendation M.3400 [10] are included here. All other functions in ITU Recommendation M.3400 [10] are not needed for this application. See ITU Recommendation M.3400 [10] for specific definitions of each function.

6.1.1 Performance Management

The SMLC collects performance-related data. The SMLC indirectly observes any performance-related data external to the LMU (e.g. number of position failures versus requests). The LMU monitors internal performance-related data and sends alarms to alert the SMLC of any anomalies.

6.1.2 Fault Management

 Alarm Surveillance/Alarm Reporting/Report Alarm.

 Alarm Surveillance/Alarm Reporting/Allow and Inhibit Alarm Reporting.

 Alarm Surveillance/Alarm Reporting/Request Alarm History.

 Alarm Surveillance /Failure Event Detection and Reporting.

 Fault Localisation/NE Fault Localisation/Request diagnostic data.

 Fault Localisation/NE Fault Localisation/Stop diagnosis in progress.

 Fault Localisation/NE Fault Localisation/Diagnostic report.

 Fault Localisation/Running of Diagnostic.

 Fault Correction/NE Fault Correction/Automatic Restoration Report.

6.1.3 Configuration Management

 Installation/Loading software into NEs.

 Provisioning/NE Configuration/Request Configuration.

 Provisioning/NE Configuration/Configuration Report.

 Provisioning/NE Configuration/Set Service State.

 Provisioning/NE Configuration/Request Assignments.

This function is supported by the Status Query operation specified in 04.71 [9]. An O&M job is defined as an unsatisfied request from the SMLC. Once the LMU has sent all required responses, the job is completed. Unanswered requests from the LMU to the SMLC are not considered jobs.

 Provisioning/NE Configuration/Assignment Reports.

This function is supported by the Status Query and Status Update operations specified in 04.71 [9]. An O&M job is defined as an unsatisfied request from the SMLC. Once the LMU has sent all required responses, the job is completed. Unanswered requests from the LMU to the SMLC are not considered jobs.

 Provisioning/NE Configuration/Set Parameters.

 Provisioning/NE Configuration/Set Service Thresholds.

 Provisioning/NE Configuration/Start Transmission Test.

 Provisioning/NE Configuration/Restart Request.

 Provisioning/NE Configuration/Restart Report.

 Status and Control/NE Status and Control/Request Status.

 Status and Control/NE Status and Control/Status Report.

 Status and Control/NE Status and Control/Control event report.

 Status and Control/Access to state information in NEs.

 Status and Control/Notification of state changes by NEs.
