Title: What is SMS Valid Period?
Post by: Mike Petrichenko on December 04, 2015, 06:55:30 AM
Validity period specifies the time when SMS expires. If SMS is nott delivered before that moment, it is discarded by Service Center. Validity-Period can be in three different format: Relative, Absolute and Enhanced. WCL supports only Relative format. In this format the TP-Validity-Period is in integer representation, giving the length of the validity period, counted from when the SMS is received by the Service Center. The representation of time is as follows:

TP-VP valueValidity period value
0 to 143(TP-VP + 1) * 5 minutes (i.e. 5 minutes intervals up to 12 hours)
144 to 16712 hours + ((TP-VP - 143) * 30 minutes)
168 to 196(TP-VP - 166) * 1 day
197 to 255(TP-VP - 192) * 1 week
