Plural network protocol wireless transmit/receive unit
First Claim
1. A wireless transmit/receive unit (WTRU) configured to communicate using a plurality of network protocols, the WTRU comprising:
- a circuit configured to make an initial communication request;
a communication circuit configured to establish a communication link in response to the initial communication request in a first direction of communication and a second direction of communication;
a circuit configured to determine a protocol preference for the first direction of communication and further configured to establish communication in the first direction according to the protocol preference separately from communication in the second direction of communication;
a circuit configured to determine a protocol preference for the second direction of communication and further configured to establish communication in the second direction according to the protocol preference separately from communication in the first direction of communication; and
a second circuit configured to determine the availability of communication services optimal for communicating user data in a different protocol from the protocol used as the communication link.

Abstract
A wireless transmit/receive unit (WTRU) communicates in a system which includes plural network protocols. The WTRU includes a circuit configured to make an initial communication request. A communication circuit establishes a communication link in response to the initial communication request in a first direction of communication and a second direction of communication. Circuitry determines a protocol preference for the first direction of communication and to establish communication in the first direction according to the protocol preference separately from communication in the second direction of communication. Circuitry determines a protocol preference for the second direction of communication and to establish communication in the second direction according to the protocol preference separately from communication in the first direction of communication. A circuit determines the availability of communication services optimal for communicating the user data in a different protocol from the protocol used as the communication link.
