In a soft handover cellular system, diversity handling operations are multistaged for a mobile connection which is controlled by an original or Source RNC (122.sub.1) and which also utilizes a secondary or Target RNC (122.sub.2). Non-Source RNCs each have a diversity handling units (DHU) which perform connection splitting and connection combining operations for all involved base stations (BS) owned by the non-Source RNC, so that only one transport connection need exist between the Source RNC and the Target RNC for the mobile connection. The Source RNC (122.sub.1) has a diversity handover unit (130.sub.1)which not only performs connection splitting and connection combining with respect to the involved base stations owned by the Source RNC, but also with respect to the one transport connection for each Target RNC involved in the mobile connection.

[ What is claimed is:] [1.]1. A mobile telecommunications system comprising:a first radio network controller (RNC) node connected to a mobile switching center for handling a mobile connection between the mobile switching center and plural base stations involved in the mobile connection, the first radio network controller (RNC) node serving a first set of base stations involved in the connection, the first radio network controller (RNC) node performing one of a first stage connection combining operation and a first stage connection splitting operation with respect to a mobile connection;a second radio network controller (RNC) node serving a second set of base stations involved in the connection, the second radio network controller (RNC) node performing one of a second stage connection combining operation and a second stage connection splitting operation with respect to the second set of base stations involved in the mobile connection; andan inter-control node link connecting the first radio network controller (RNC) node and the second radio network controller (RNC) node for carrying one of a second stage connection combining result from the second radio network controller (RNC) node to the first radio network controller (RNC) node and a first stage connection splitting result from the first radio network controller (RNC) node to the second radio network controller (RNC) node.
