  2. Agenda • The where, who and when about the sts data.. • Capabilities of the TOOL • Let’s surf Together

  3. A quick look a what is ESPA • Automated tool that provide passive measurements on a 7X24X365 scheme based. Users access to the tool through a web site. It is an Internal Ericsson tool. • http://internal.ericsson.com/page/hub_globalservices/products/delivery/advise/support/espa/index.html

  4. Policies for the use of ESPA http://138.85.87.6/espa_wcdma_cingular/espa_login.asp • Unique user • It is not allowed to share your user with a partner • Change your password on a monthly based • You are working in the UMTS project

  6. Counters… Counters from all active PM are written to an XML file inside of the NE. The Statistic file (every Result Output Period (ROP) is collected by the user from the OSS-RC every 15 minutes. Automated process inside ESPA are up and running, ready for collect the files.

  7. ESPA

  8. ESPA is a tool that provide Passive Measurements

  9. The ESPA levels

  10. The Universe, Aggregate the data according with your universe. At the end The formula in all the levels is the same. The only difference Is the Network level and aggregation level that you are looking

  11. Capacity Management related KPI indicators …

  12. RF Power and Channel Element Utilization Monitoring RBS Counters pmAverageRssi, pmTransmittedCarrierPower, pmTransmittedCarrierPowerNonHs, pmNoOfRadioLinksSf4-256 (UL-DL), pmApomcOfUlLinkCap Call Set up Blocking KPI Number of RAB establishment requests denied due to congestion, the number of RRC connections terminated due to congestion, the number of RABs switched down due to congestion

  13. Admission Monitoring pmSumOfSampAseDl/UL:Total ASE DL/UL(sum of all sample values recorded) This counter is the sum of all sample values during the ROP (15 min) of total DL ASE in use in the cell. There is an internal level (gauge) counter that monitors current level of ASE in the cell. That counter is read with a regular interval (more often than 15 min) and each time it is read the value is added to this counter and the counter pmNoOfSampAseDL/UL is increased by one, sampled every 30 seconds. pmSumOfSampAseDl/UL: Number of samples of Air interface Speech Equivalents (ASE) DL/UL . Condition: increased at every occasion when the corresponding Sum counter is increased, sampled every 30 seconds.

  14. Five main indicators in just one tool…lets surf together
