To provide adequate scalable support, additional distributed functions are required to support the functional entity. See functional components described in the document It is envisioned the presence of multi wireless access, such as 802.11, 802.16, UMTS, forming an heterogeneous composition of macro and micro cells. Performing network initiated handover has the main implication that the network has first to assess the terminal view of the network. Signal level evaluation is a important matter when coming down to user mobility. Neighborhood discovery relates to the above assumption when neighborhood scanning is requested from the network. It is expected these functions to be available on the terminal side. Assumptions (ii) |
