Hi Rajesh and Denis, If we are in area with multiple networks (so multiple MCCs), lets pass only received emergency-list from the servicing network, where ME is registered to, and discard possible notifications from other network's emergency-number notifications:
TS 22101, ch. 10.1 "The UE shall regard these emergency numbers as valid in that country only (as identified by the MCC) and shall discard them when a new country is entered." One think in one of those emails focusing on this discussion (Waldo's comment) was: >The modem will typically already analyze the new emergency-numbers, >filter out the ones that are not applicable and merge the numbers from >the various sources in the right priority.... My idea first in analyzing was to compare new emergency numbers with already sent emergency numbers (default-list/SIM EFecc-list), and send those up, if new emergency numbers compared to the old already sent ones were received. OK, probably in many cases modems will do this analyze itself, and send only new ones to the oFono. I don't know if it's actually dangerous, if oFono passes all network emergency numbers received from the modem (filtered or not by the modem). OK, then it's possible that some ECCs are reported twice. On the other hand, network ECCs (if MCC matches) should always be valid ones, suitable numbers, in spite of, where mobile is located. So it should be valid to acknowledge those new numbers always to UI in spite of, what numbers are sent to UI in initialization phase. Perhaps then the only thing to be analyzed could be that country-code item. Network downloaded emergency number-list can also contain emergency call type in the category-field (for instance "Police", "Ambulance"...). This kind of information is not included for example in SIM EFecc-file, so Emergency-number property returns in this moment just the ECC-number without the category. What do you think, should this also be included in the Emergency-property?
