TEMS Investigation 17.2.3 Release

1. New Features

1.1. New Supplied Device: Samsung Galaxy S6 Edge+ SM-G928F

This is an LTE Category 9 device. It can be used to compute POLQA audio quality scores in an ACU R2 configuration (M2M/M2F). The device is VoLTE-capable but requires customer-specific customization with VoLTE firmware.

  • Frequency bands:
    • LTE 2100 (Band 1), 1900 (B2), 1800+ (B3), AWS (B4), 850 (B5), 2600 (B7), 900 (B8), 700ac (B12), 700bc (B17), 800DD (B20), 700 APT (B28), TDD 2600 (B38), TDD 2300 (B40)
    • WCDMA 850 (Band V), 900 (VIII), 1900 (II), 2100 (I)
    • GSM 850, 900, 1800, 1900
  • Throughput capabilities:
    • LTE Category 9 (450/50 Mbit/s)
    • HSDPA Category 24 (42 Mbit/s), HSUPA Category 6 (5.8 Mbit/s)
    • GPRS/EDGE Class 12
  • Real-time control capabilities: See section 3.1.2.
  • Google Android 5.1.1
  • WLAN 802.11a/b/g/n/ac (2.4 and 5 GHz)
  • Integrated GPS with A-GPS support
  • Chipset/CPU: Samsung Exynos 7420, 8-core, 4x 1.5 GHz, 4x 2.1 GHz

1.2. Control Functions on Samsung Chipset Devices

Vital control functions have been implemented for selected devices built on a Samsung chipset: at the time of writing, Galaxy Note 5 SM-N920I, S6 SM-G925F, and S6 SM-G928F.

  • RAT lock
  • Band lock
    GSM cell lock (ARFCN + BSIC)
  • WCDMA cell lock (UARFCN + SC)
  • LTE cell lock (EARFCN + PCI)

Note: After applying a cell lock control function to a Samsung chipset device, you need to deactivate and activate the device in TEMS Investigation for the function to take effect.

1.3. Video Call Enhancements

  • Video call control has been implemented on the Samsung Galaxy S6 SM-G920F and Samsung Galaxy S6 SM-G928F.
    • When setting up a ViLTE call you have to initially start a VoLTE call and then add video. Translating this into a script there should be a parallel activity where it in one leg is a dial-wait-video add-wait(length of call)-video remove-wait-hangup, and in the other leg wait-answer-video accept.
    • Setting up a CS video call is just through a video dial, i.e. no “video add” as in the PS case.
  • The video call state machine has been extended to support the “CS video call” state.

1.4. Additional information on missing connect option

When a device is detected with no license, there is now additional information available on which particular license option that is missing when hovering the device in the equipment navigator.

1.5. Chinese Speech Sentences on iPhone 6

Chinese sentences can now be used when measuring audio quality with iPhone 6 devices in an ACU R2 configuration.

2. Corrected Bugs

  • On-Device Facebook utility signing problem
  • Missing initial information elements in text export
  • DRT 4301 scanner and Motorola VML750R3 UE can now be detected simultaneously
