Both serves different purpose Both serves different purpose where IMSI is used to identify a subscriber by operator at the same time MSISDN is used to route the call. In short MSISDN is the number which is used for dialing

Ref: http://tech.queryhome.com/5683/imsi-vs-msisdn?show=5726#a5726

Now coming to your query, if we use IMSI as a subscriber identity then services likes MNP, IN would become impossible of we need to device the mechanism which will be similar to MSISDN only. I would suggest to go through the link above and a lot of doubt would get cleared.

Is it mandatory to have an MSISDN associated with a IMSI record on the HLR?

M2M devices and data cards without voice services may not need an MSISDN, how are such records maintained on the HLR? Is it mandatory to have an MSISDN associated with every IMSI record on the HLR? If yes, can we just have a dummy/fake MSISDN associated in such a case so to avoid consuming/wasting a real MSISDN?

LTE: Why presence of Tracking Area Identity (TAI) and E-UTRAN CGI (ECGI) IEs is mandatory in Uplink NAS Transport ?

Uplink NAS transport message is used between eNodeB and MME to pass NAS messages between UE and MME transparently.
Since eNodeB has already communicated TAI and E-CGI as part of "Initial UE message" and MME knows current serving (cell and tai ) of UE then why both IEs are mandatory in Uplink NAS transport. I think it should be optional and it should be included in the message when there is a change in serving (cell or tai or both).
