Abstract
Upon reset of a control node (261) of a radio access network (24) which controls connections with user equipment units (30) in a connected mode, a message (102) indicative of the reset is sent between nodes of the radio access network. The message results from occurrence of a reset procedure (104) affecting the control node. The message includes an element which collectively indicates that a subset of the connections (i.e., not all of the connections) controlled by the control node are to be released. Inclusion in the message of the element, also known as the subset reset element, facilitates return to an idle mode of the user equipment units involved in the subset of the connections. By virtue of inclusion of the subset reset element, the message need not go to one extreme of listing individually each of the connections affected by the reset, nor to another extreme of specifying all connections controlled by the control node.
