Packet Domain Command(GPRS)

1.32. UMTS packet Domain commands

This clause defines commands that a TE may use to control a MT supporting packet switched services. Other aspects of a Packet Domain MT are described in 3GPP TS 27.060 [34].

It is anticipated that Packet Domain MTs will vary widely in functionality. At one extreme, a MT supporting CS/PS or class-A mode of operation might support multiple PDP types as well as circuit switched data, and use multiple external networks and QoS profiles. At the other extreme a MT supporting only PS or class-C mode of operation might support only a single PDP type using a single external network, and rely on the HLR to contain the PDP context definition.

A comprehensive set of Packet Domain-specifc commands is defined in clause 10.1 to provide the flexibility needed by the more complex MT. The commands are designed to be expandable to accommodate new PDP types and interface protocols, merely by defining new values for many of the parameters. Multiple contexts may be activated if the interface link-layer protocol is able to support them. The commands use the extended information and error message capabilities described in this specification.

For MTs of intermediate complexity, most commands have simplified forms where certain parameters may be omitted.

For the simplest MTs, and for backwards compatibility with existing communications software, it is possible to control access to the Packet Domain using existing modem- compatible commands. A special dial-string syntax is defined for use with the D command. This "modem compatible" mode of operation is described in subclause 10.2.

A discussion on the interaction of the AT commands, Packet Domain Management and Packet Data Protocols, together with examples of command sequences for a number of applications may be found in 3GPP TS 27.060 [34].
