SERVICE-BASED CELL RESELECTION

摘要

The present invention relates to methods, a system, a network element, a terminal device, and computer program products for cell selection or reselection in a multi-radio network environment involving at least two different radio access technolo-gies. A service preference information which indicates service preferences for dif-ferent radio access technologies can be set at a network element and is sent to at least one terminal device. At the terminal device, the service preference informa-tion is detected and a serving cell is selected based on the detected service pref-erence information. Thereby, the network is capable of performing service-based control of cell selection or reselection of the terminal device upon initiating access for a certain service in an overlaid multi-RAT environment. This in turn enhances network utility, operation and performance.
