Abstract
The invention relates to a method for managing the mobility of a mobile terminal, while receiving a service via an access node of a mobile communication network. The mobile communication network has overlapping pool areas, while the access node is assigned to at least two pool areas simultaneously. After the UE changes to the access node of the overlapping area, it is proposed that the mobility management entity serving the UE arbitrarily selects a prospect user plane entity for transporting service data into the next pool areas, and requests from the service provider information about UPEs handling this service. After the actual attachment to an access node within the new pool area, the handover is finalized by changing the UPE from the old one to the selected UPE in the new pool area. Thereby, the data path from the service provider to the UE is constantly being optimized.
