Sprint PCS
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.
