In a soft handover cellular system, diversity handling operations are multistaged for a mobile connection which is controlled by an original or Source RNC (1221) and which also utilizes a secondary or Target RNC (1222). 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 (1221) has a diversity handover unit (1301)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. |
