ABSTRACT:
A method, apparatus, software product, and network element enable a user equipment to operate in an idle mode, to sense a change in the broadcasted location area, and to then report that change to a network without requiring a dedicated connection to the network. This embodiment is achieved by sending an identifier via an uplink transport channel, and then the user equipment receives a resource allocation that is based at least partly on the identifier. The user equipment provides an uplink signal via the allocated resource, including a user equipment identity in the uplink signal. When the user equipment receives confirmation, including the user equipment identity, then the user equipment reenters the idle mode. The uplink signal provided an update as to the location area of the user equipment, although other types of signals can instead be provided this way to the network.
