04.603GPPGeneral Packet Radio Service (GPRS)Mobile Station (MS) - Base Station System (BSS) interfaceRadio Link Control / Medium Access Control (RLC/MAC) protocolRelease 1999TS

This message may be sent by the network on the PACCH. It may be sent to a mobile station with UTRAN capability. A mobile station with no UTRAN capability shall ignore this message.

The message provides the mobile station with a list of the UTRAN frequencies used by the network. These frequencies may be used in the cell selection procedure, see 3GPP TS 25.304.

If both an UTRAN Frequency List Description struct and an UTRAN Frequency List information element (3GPP TS 04.18) are received, the mobile station shall use the one most recently received.
