The secret code *#0011# (Samsung specific) is dialed to display the RRC states, which are saved at regular intervals using Android logcat.\u00e2\u20ac\u0153 \u00e2\u20ac\u201c Secret codes are hardware-specific, and this is precisely the reason our system has not been ported to support every existing device. Furthermore, the limitation is not so much due to particular handsets, but rather the chipsets they use, so the approach works with any device using the same chipset and in that way requires special hardware<\/li>\n<li>hence the more specific statement is wrong: \"RILAnalyzer, which enables to accurately gather and correlate control plane and user plane events on Android handsets. Currently the tool is sup- ported on rooted Android devices with only Intel\/Infineon XGold chipsets. Our tool does not have such dependencies.\u00e2\u20ac\u009d In addition it implies that their system did not require rooted Android devices (an important limitation of our work), which as far as I know could not be true on any standard Android device.<\/li>\n<li>\u00e2\u20ac\u0153We propose an entirely mobile based framework\u00e2\u20ac\u009d \u00e2\u20ac\u201c not sure how a phone connected to a PC is entirely mobile<\/li>\n<li>Based on the above point, claiming that the mechanism is on-the-phone is inaccurate: \"we propose for Android smartphones an on-the- phone mechanism to detect background applications that due to bad design (given the network\u00e2\u20ac\u2122s settings) or their malicious nature (exploiting the network\u00e2\u20ac\u2122s settings) lead to above mentioned inefficiencies.\"<\/li>\n<li>\"Recent works, [9], [6], have analyzed such applications. How- ever, they focus on energy efficiency and perceived end user experience, and not on measuring an application\u00e2\u20ac\u2122s impact on the network\u00e2\u20ac\u2122s signaling load and energy consumed, for communicating a unit of data.\u00e2\u20ac\u009d - inaccurate citation of RilAnalyzer - it focuses on energy and signalling rather than perceived end user experience, just not for communicating a unit of data<\/li>\n<li>\"We adopt a novel approach to find and record the actual RRC state of the device at any given instant. Secret codes are used to open Android hidden menus [8]. The secret codes are manufacturer specific numeric\/symbolic sequences, which can be dialed from the device to access hidden menus, run diagnostic tests, and reset parameters of the device.\u00e2\u20ac\u009d\u00c2\u00a0\u00c2\u00a0- the approach is somewhat novel, however described in our work and in my opinion needs proper attribution as well<\/li>\n<\/ul>\n<p>My feeling is that it was not difficult to cite our work more accurately, which might have also helped to clear up some of inaccuracies of their own work. I think so especially because they have been in touch with us since the end of August, received source code of our system on the 8th September (published on github) and received our assistance in running it. Furthermore, camera-ready version of our paper which appeared in IMC\u00e2\u20ac\u212213 (October 23 - 25) was also published online from 21st August.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Not even two weeks since IMC pass and we have the first citation of our RilAnalyzer paper!
