The attach procedure is finished with the allocation of the IP address to the UE and establishment of a default bearer (basic IP connectivity). This bearer is alive during all the time the UE is registered/attached in the network (“the always on concept”). The default bearer can be considered/mapped to a PDP context from UMTS/GPRS network. However it is described by Rel. 8 QoS parameters.

Why in LTE we establish a PDP context during Attach procedure but in UMTS it is not. Any pointers, it will also be good if someone can describe the Attach procedure in detail (though there are so many blogs but don't know which one is to follow)

During a LTE attach, MME may send the UE a EMM Information message with Universal time and local time zone IE. This IE contains Year, month, day, hour, min, sec.
My problem is that I can not find any reference yet about what should be the value of the year. Is it calculated from 1900 or 2000 or as it is ? or there is some other reference year ?
Any reference spec with this particular information will be highly helpful.
