GCF REFRESH enhancements on Interlab TS DEVICE/UICC

Interlab Test Solution DEVICE/UICC covers new “REFRESH” test cases according to latest GCF Work Item #230

Services like remote subscription and roaming management of mobile devices require a reliable and correct communication with the integrated UICC. Such actions are handled via the specific USAT “REFRESH” command.

Via its Work Item WI#230, GCF has extended its conformance requirements to sufficiently cover the required “REFRESH” command enhancements for 

  • a 3G session reset (with an IMSI change)
  • a UICC reset (with IMSI change).

The extended test coverage is binding for 3G and LTE USAT conformance criteria and has been implemented in the USAT test specification 3GPP TS 31.124.InterLab Test Solution DEVICE_UICC

In order to cover these new conformance criteria 7layers has extended the coverage of its Interlab Test Solution DEVICE/UICC (Test Platform TP 146). In combination with the R&S® CMW 500 the solution fully covers the new GCF WI#230.

With this extension 7layers once more demonstrates its concept of keeping up with the latest GCF and 3GPP requirements and extending its test solution continuously.

The Interlab Test Solution DEVICE/UICC not only covers the latest “REFRESH” certification test cases. It supports the verification of  a comprehensive number of terminal/UICC interface conformance requirements of GCF and PTCRB for 3G and LTE plus specific certification criteria of China Mobile and Verizon Wireless.

Field Trial testing for GCF now includes LTE TDD

Field Trial testing at 7Layers covers new LTE TDD requirementsGCF certification at 7Layers

Field Trial testing is part of the GCF Certification scheme. By requiring tests on live networks in addition to conformance tests in a GCF Recognized Test Organization (GCF RTO) such as 7Layers, manufacturers obtain practical insight into their device’s interoperability.

For each feature being tested, field trials are performed on a specified number of infrastructure combinations on live networks. Leading GCF operators are making their networks available for field trials, providing the relevant network information and appropriate drive routes to enable field trial test organizations to perform the required tests correctly and efficiently. The GCF Field Trial Agreement Group (GCF FTAG), chaired by Michael Ciplajevs of 7Layers, meets at regular intervals to further develop and maintain criteria for Field Trial test scenarios.

LTE TDD Field Trial in China Mobile Network

China-Mobile-Logo-2013[1]During the GCF Field Trial Agreement Group Meeting held in Dubai it has been established that terminals supporting LTE-TDD and/or LTE-FDD have to pass at least one LTE TDD field trial configuration. CMCC (China Mobile) is the only GCF Field Trial Qualified Operator (FTQO) worldwide that covers LTE TDD Band 38, 39, 40 and 41.

The Field Trial drive routes are located in Jiaxing and Hangzhou.

[expand title =”Read more”]

Commercial near field communication (NFC) services, using a mobile handset’s UICC as secure element, are beginning to be deployed around the world.

UICC based NFC technology enables the development of secure and user-friendly services, such as payment, identification and others. However, service providers, mobile network operators (MNOs) and implementers of mobile NFC payment services (e.g. banking, transport, access control, etc.) are concerned that mobile phones with integrated NFC technology are working correctly. To ensure Interoperability, Connectivity, Data Security and Accountability of UICC based NFC services, standardization organizations have therefore developed requirements and specifications that have to be fulfilled by NFC-enabled mobile phones.[/expand]

NFC test requirements of GCF and PTCRB
