Hi Yichen, Sabine and ALTO working group,
With regard to the review from Yichen, I have the following comments. First, the leading zeros issue is fine. Even in the LTE standard, leading zeros are allowed. MNC, assigned by National Authority can be either 2 or 3 digits. If the 2-digit MNC is used, then the PLMN will be like: 262-20; for 3-digit MNC, PLMN is like: 262-020. The example in 3.2 is not clear, because the contries can not be identified only by MNC. Second, 7-digit eCI is mandatory, including 20-bit eNB and 8-bit CI. There must be some typos in the examples with 6-digit eCI. Third, 1234800/18 definitely matches anything starts with 12348, so the example in 3.4 isn’t quite right. At last, I suggest authors to revise the expression of ecgi, which is likely to be confused with the standard ECGI. A-ECGI may be an option denoting ALTO-ECGI. Best, Geng ________________________________ From: alto <[email protected]> on behalf of Yichen Qian <[email protected]> Sent: Thursday, November 30, 2017 9:33 PM To: Sabine Randriamasy; IETF ALTO Subject: [alto] Review of draft-randriamasy-alto-cellular-adresses-00 Hi Sabine and ALTO working group, I just reviewed draft-randriamasy-alto-cellular-adresses-00 and below are my comments. Most of them are about the examples given in the draft. At the begin of section 3, 'The predent draft proposed …' -> 'The present draft proposed …'. In section 3.2, MNC is defined as a 2-3 digits decimal number without leading zeros. It’s not consistent with the example below 'MNC value 020 stands for Network N2 …'. Section 3.2 also mentions that ECI is a 7 digits lower-case hex number. While in the third example of section 3.4, 'ecgi:311.481:123480' and 'ecgi:311.481:12348d' only have 6 digits for ECI. Another confusion in the third example of section 3.4 is that I think 'ecgi:311.481:12348d' also matches the ECI that starts with the 18 bits 0x12348. Your feedback is highly appreciated.
