Packet Data (TMO)
8.4.2 Data Only Mode
This is a user menu selectable option that is remembered at power up and if selected, normal voice
calls are not permitted and all non emergency calls will be rejected.
Both set up and reception of emergency calls is still permitted.
8.4.3 Voice Priority Mode
If any voice call activity occurs during a data session, it will have priority over packet data. The
packet data session will be suspended until voice call completion, after which the packet data
session will be resumed.
Voice priority is the default mode if the user has never explicitly selected an interaction mode.
8.5 Packet Data MMI Operation
The terminal shows an indication to the user whenever the PDP context is active and it shows the
amount of used slots. The terminal has a separate indication to the user to indicate when data
transfer is in progress.
8.6 Priority of Packet Data
The packet data service access signalling for a packet data channel (PDCH) have the same priority
as that for normal call set up.
8.7 Terminal Generated ICMP Messages
In the case of non delivery due to the terminal's environment, the terminal will generate ICMP
messages and address them to the TE2. The available messages include:
• No radio coverage
• Failed transmission
• Service interaction
8.8 IP Addressing
8.8.1 Wide IP Address
An IP address may be assigned to the MS by the system when the terminal registers for data mode
operation. When assigned, the address is used by both the terminal and the connected external
application as the source address in the IP packets delivered to the infrastructure and received as
the destination address from the infrastructure.
8.8.2 Local IP Address
By default both TE and MT have their own IP addresses: "10.0.0.100" and "10.0.0.101" respectively
as specified in [Ref 4] clause 4.10.2. These addresses are used by TE2 and MT2 for local datagram
transmissions between TE2 and MT2 only and are not passed to the SwMI.
8.9 Advanced Link
Dimetra IP does not support Advanced Link Flow Control, but Advanced Link Flow Control is
supported by the terminals.
