PS State
Description
Attached
Synchronization and attach have been performed. A default bearer has been established.
Depending on parameter
a Radio Resource Control (RRC) con-
nection is still established or has been released. To send or receive SMS messages, to
start an inter-RAT handover or to establish an SCC connection, an established RRC con-
nection is required.
Connection
Established
A dedicated bearer has been set up. An RRC connection has been established (during
attach or during connect).
User data can be exchanged via shared channels. The R&S
CMW can vary connection
parameters, perform transmitter and receiver tests, or initiate a handover.
A number of control commands initiated by the instrument or by the UE switch between
the listed states. The following figure shows possible state transitions.

the following transitory states:

Displayed e.g. during attach or when the channel changes for an established con-
nection.
●
Connection in Progress
Displayed during connection setup.
●
Sending Message
Displayed while an SMS message is sent to the MS.
