Abstract: Methods and systems for message-origination-based global title translation include receiving a signaling message and determining whether global title translation is required. In response to determining that global title translation is required, a lookup is performed in the global title translation database. The lookup is based on the called party address and the originating point code in the signaling message. The destination point code from the global title translation is inserted in the signaling message. The signaling message is then routed to its intended destination based on the destination point code and optionally the originating point code in the signaling message.

Abstract: A method for selecting a transport format combination (TFC) in a wireless transmit/receive unit (WTRU) is disclosed. The WTRU is configured to process more than one coded composite transport channel (CCTrCH) for uplink transmission. The WTRU estimates a transmit power for each of a plurality of available TFCs and selects a TFC for each CCTrCH such that the sum of the estimated WTRU transmit power for selected TFCs is within a maximum WTRU transmit power.
