SDS - Short Data Services
7.3 Pre-Defined Status
7.3.1 Sending Status
The mobile status service is provided using SDS Status [Ref 1], clause 13. The terminal user can
select from a list of up to 100 pre-programmed alphanumeric aliases each of which corresponds to a
status value. The valid range of uplink status values is a set of provisioned parameters (min/max).
If the terminal is not provisioned for targeted status, the status value will be sent over the air
interface to the address of the selected group.
The terminal will recognize the General status ack sent by the SwMI, as well as negative
acknowledge as defined in [Ref 10].
In TMO if no status ack or negative ack is received, the terminal will retry sending the message. The
number of retries and amount of time to wait before retrying are provisioned parameters. The user
will be notified regarding the delivery status.
As there is no ack for DMO status messages, the user will be notified only of sending the status
message.
The terminal should not initiate sending of status messages on a traffic channel.
7.3.2 Targeted SDS Status
If the terminal is provisioned for targeted status, the status value is sent over the air interface by
default to the target last sent to.The user also has an option to specify a different individual user or
group to send the message to.
7.3.3 Receiving Status
The terminal accepts status messages on any address it is monitoring. The terminal can be pre
programmed with the appropriate text associated with each status value.
The user is notified when a new status message has been received.
Upon receiving an incoming status message, the stored text corresponding to the status value will
be extracted and placed in the text message buffer as a text message. Receiving a status will cause
the terminal to display the message mail screen, allowing the user quick access to read the
message. A received status can be stored in the terminal text message buffer.
7.3.4 PEI Access to Status
The PEI provides access for external applications to send and receive status messages (See
Paragraph 7.1.2 "External SDS Application Support").
7.4 Text Message Service
The terminal supports an internal text messaging application using the TETRA SDS Transport Layer
(see Paragraph 7.1.1 "Transport Layer Services").
The terminal is capable of sending and receiving up to 140 bytes of payload data (which can be up
to 160 characters if 7-bit encoding is used).
7.4.1 Sending a Text Message
The terminal provides an edit facility for composing and editing a text message.
IMPORTANT:

Editing is available only for the full keypad terminal.
