IOTA Provisioning
The 3GPD parameters are easily configured using Over The Air Provisioning. Sprint PCS uses
IOTA (IP-based Over The Air) for their OTA provisioning system. IOTA uses packet data calls
to transfer the configuration data to the modem. These IOTA data sessions can be network
initiated or Client initiated. Network Initiated IOTA is the preferred method. An automatic
network initiated IOTA session occurs when the module first registers onto the Sprint
network. This IOTA session is queued when Sprint originally sets up and 'activates' the
account. In their current implementation, Sprint imposes a 72 hour expiration timer for this
queued IOTA session. An IOTA session has a device time out of 15 minutes. If unsuccessful
after 15 minutes, the status changes to fail and the module stops trying. A normal IOTA
session takes from 1 to 3 minutes. To register on the network, the module needs a
sufficient signal and requires manual provisioning with the MDN and MSID. The IOTA
session will occur and populate the 3GPD parameters. If it is the first IOTA session, it is
called a Network Initiated Initial Provisioning (NIIP.)
NOTE:
An IOTA session MUST occur while the device has sufficient signal and is
registered on the Sprint PCS Network. A session will not be successful if the
device is out of coverage or not properly registered on the Sprint PCS network.
