Projects

Public Safety Broadband Demonstration Network Testing

The PSCR program has established a test plan with three major phases of testing and evaluation. The PSCR program is also developing a conformance and performance test process with industry fora.

All test results the PSCR program publishes will be non-attributable to the industry stakeholder.

Please send questions or feedback to 700MHz@its.bldrdoc.gov.

Three-Phase Test Plan

Stakeholders who have an executed CRADA will have access to the detailed test procedures and work with PSCR in refining those in future updates of the test plan.

Phase 1: Basic Functionality Testing

» Phase 1: Basic Functionality Tests, (SEP 12, 2011) is available here — click to open or right-click to save or download the PDF.

Basic functionality testing will determine if the LTE equipment submitted for use in the PSCR demonstration project has been configured correctly to achieve a minimal level of functionality. Tests will include:

  • Physical layer tests to ensure that the submitted equipment will not interfere with other existing 700 MHz LMR, PSCR demonstration systems

  • Messaging/protocol tests

  • Public safety application tests

  • Basic performance tests

Phase 2: System and Node-Level Testing

» Phase 2: Part I, (OCT 6, 2011) is available here — click to open or right-click to save or download the PDF.

Comprehensive system and node-level tests include:

  • In-depth and advanced performance testing

  • Multi-user, loaded network stress testing

» Phase 2: Part II, (OCT 6, 2011) is available here — click to open or right-click to save or download the PDF.

Multiple EPC signaling related tests, operational and load testing include:

  • Stress Tests: These tests will examine the loading and potential capacity of the target cell

  • Performance Tests: The performance tests in this part relates to latency

  • Messaging/Protocol Tests: These tests cover the areas of security, interoperability, and failure modes

  • Application Tests: Multiple types of tests include network O&M, Alarm/Fault Reporting and the Status Home Page

Phase 3: Advanced Feature, Conformance, Interoperability, and Roaming Testing

Advanced feature, conformance, interoperability, and roaming tests will include:

  • Network architecture type testing, including evaluation of various PLMN, eNUM, and IP implementations

  • Interoperability testing that includes testing the EPC and inter-connecting multiple EPCs

  • LTE-to-LTE (public safety-to-public safety) handover testing and evaluation

  • QoE using QCI and other QoS features

  • Access testing of Allocation Retention Priority feature for priority and pre-emptive features

  • VoLTE implementations

  • Interoperation with LMR networks using BSI

  • IMS and application implementations

  • Roaming to other LTE bands and to 3G systems in other bands (both EVDO and HSPA)

Conformance and Performance Test Process

PSCR is developing a conformance and performance test process with industry fora for both UE and EPC infrastructure. This process will be posted here when available.
