FLEX, ReFLEX and InFLEXion Messaging Protocol Overview
The delivery of advanced messaging is augmented by a family of new Motorola
over-the-air (OTA) message protocols. The FLEX messaging protocol provides one-way text
messaging, and the InFLEXion messaging protocol provides two-way voice and data
messaging. Two-way messaging, using the ReFLEX and InFLEXion protocols, provides
guaranteed message delivery because a received message is acknowledged by the
communicator. If a message is not acknowledged after a transmission, the system retransmits
the message intermittently until it is received.
The primary difference between the ReFLEX and InFLEXion protocols is in the outbound
(transmitter to communicator) signal path. ReFLEX is strictly a data messaging protocol,
whereas the InFLEXion protocol supports voice messaging. The protocols are identical with
respect to the inbound (communicator to receiver) signal path.
FLEX Messaging Protocol
The FLEX messaging provides reliable one-way text messaging service, while maintaining
long battery life on the subscriber unit.
ReFLEX Messaging Protocol
Key features of the ReFLEX messaging protocol are the ability of the system to guarantee
delivery of a data message and the ability of the subscriber to reply to the message. These
functions create the closed-loop performance that makes advanced messaging a quantum leap
in wireless communications.
Message Response
The ReFLEX system enables the subscriber to originate a message and offers the subscriber
two ways to respond to a received message:
• After receiving a message, the subscriber selects a response from a subscriber-specific list.
This list has up to 120 pre-established, subscriber-specific messages stored in the
communicator and in the terminal. To optimize air time, only the selected message index
identifier is sent back to the terminal, which then sends the associated message.
• The subscriber selects a response from a list the sender imbedded into the message. After
selection, the subscriber can return the response to the system where the sender can
access and review it.
