Patent ID: 8274946

Claim:
A method for use in a wireless transmit/receive unit (WTRU) that includes an interworking function and a plurality of lower layer devices, wherein the lower layer devices are capable of communicating using respective different radio access technologies, the method comprising: the interworking function receiving a first link actions request primitive from an upper layer entity, wherein the first link actions request primitive includes a plurality of parameter sets to trigger multiple independent actions on multiple links that are associated with a plurality of lower layer devices, wherein each parameter set is associated with a specific link and includes: a link action parameter, wherein a value of the link action parameter indicates an action to be taken by a corresponding lower layer device; and an execution time parameter that indicates a time to elapse before the action needs to be taken by the corresponding lower layer device; the interworking function sending a second link actions request primitive to the plurality of lower layer devices including a plurality of parameter sets to order each lower layer device to perform the action indicated by the corresponding link action parameter for the lower layer device; and each of the lower layer devices performing the action indicated by the corresponding link action parameter for the lower layer device on a condition that the time indicated by the corresponding execution time parameter has elapsed.
