Abstract
To facilitate inbound mobility for an access terminal, different virtual active sets are employed for different types of access points or cells (e.g., HNBs versus macro cells). In addition, different lists of permitted cells are maintained for these different types of access points or cells. Also, a frequency quality estimate for inter-frequency event triggering may be based on measurement of a single cell present in a virtual active set (e.g., a dedicated HNB virtual active set).
