The technology in this application provides a method and apparatus for efficiently using common uplink radio resources, e.g. a common uplink enhanced-dedicated physical channel (E-DCH) resource. A UE releases a common E-DCH resource very quickly after a completed transmission. In addition or alternatively, a base station may release a common E-DCH resource configuration from the network side to free up common E-DCH resources for use by other UEs. A low overhead signaling scheme for quickly and effectively releasing of common E-DCH resources between a UE and a base station is also described. For example, existing signaling fields on protocol layer 2 (L2) or layer 1 (L1) may be used. In one preferred example embodiment, signaling fields already in use in a CELL_DCH service state are given a different meaning for UEs in a CELL_FACH service state so that common E-DCH resources are quickly and effectively released.

A method is provided of providing a service to a user terminal. According to this method, a first network agrees with the user terminal to provide the service at a certain charge rate, then starts to provide the service. Subsequently at least one other network is invited by the first network to provide the service. The first network receives at least one offer from the other networks to provide the service to the user terminal. The first network then accepts one of the offers, such that the one of said other networks thereafter provides the service and charges the user terminal without the first network being involved.
