An omnibus connection release message transmitted from a control node of radio access network is used to release plural radio connections, thereby obviating problems attending transmission of plural release messages. In accordance with a first example, a control node of the radio access network prepares the omnibus release message so that, when a first selected parameter thereof has a predetermined value, all radio connections controlled by the radio network control (RNC) node are released. The first selected parameter can be included in a mobile terminal global identity information element of the omnibus release message (e.g., in a Radio Network Temporary Identity (U-RNTI) information element of the omnibus release message, such as a Serving Radio Network Temporary Identity (S-RNTI) information element).
