oFono Certification Testing *************************** Introduction ============ The aim of this document is to briefly describe the GCF certification process and how the oFono projects intends to help make obtaining the relevant certifications easier. GCF certification ================= All european network operators require a device to be certified for their network prior to being sold. While each operator defines their own set of requirements, a common set is defined by Global Certification Forum, or GCF. In North America, these requirements are defined by PTCRB. Certification is achieved by successfully passing a set of test cases, which are defined in various 3GPP specifications. The testing methodology is to perform end-to-end testing. The tests are effectively testing the modem hardware, the telephony stack and the applications simultaneously. In effect, any change to the above components requires the testing to be performed again. There is no consideration for separate component testing. The Goal ======== While it is not possible to certify oFono directly as a GCF compliant software stack, it is possible to alleviate some of the work required for obtaining such certifications in an end-product. To accomplish this, oFono team will begin running all 3GPP test cases that are deemed relevant to achieving the above goal. The short-term approach is to perform manual test case runs to establish a baseline and fix any issues discovered. In the longer term, we will be building more advanced testing tools. The goals are automated testing to detect regressions and a full SIM toolkit test suite. Test case relevance and selection ================================= Many of the defined test cases are not relevant to the telephony stack and applications; such test cases include testing of the modem roaming behavior, particular radio frequency details, etc. These cases are not considered here; only test cases directly applicable to the telephony stack or applications will be considered. All other test cases are assumed to be covered by the modem hardware manufacturer or device manufacturer as part of the full product certification cycle. Test cases considered applicable ================================ Below is a list of conformance test cases considered relevant to this effort: - 3GPP 51.010-1: 2G conformance specification section 22.214.171.124, 126.96.36.199.1, 188.8.131.52.2: NITZ (network identity and time zone) section 26.8.x : Tests related to circuit switched call control section 26.9.x: Structured procedures (MO/MT calls, emergency calls) section 31.x: Test of supplementary services section 34.x: Short Message Service section 44.2.1: Test case requirements for GPRS mobility management section 44.2.2: Attach/Detach procedure - 3GPP 34.123-1: Protocol conformance specification section 6.1.1.x: PLMN selection section 184.108.40.206: Emergency calls section 10.x: Circuit Switched Call Control (CC) section 11.x: Session Management Procedures section 12.2.x, 12.3.x: PS attach/detach procedure section 13.x: General tests (Emergency calls) section 16.x: Short message services - 3GPP 31.121: USIM application test specification section 6.x: Security related Tests - 3GPP 51.010-4: SIM application toolkit conformance specification section 27.22.x : SIM Application Toolkit - 3GPP 31.124: USAT conformance test specification section 27.22.x: USAT Application Toolkit NOTE: Many of the tests related to (U)SAT are described in ETSI TS 102.384 and not in the above 3GPP specifications.
