Abstract: front page image
(EN)

In a cellular radio system cell identities, in particular the E-UTRAN Physical Layer Cell Identities (PCIDs), are grouped in accordance with the area, in particular the Tracking Area, to which they belong to in a message transmitted from a radio base station to a mobile station. In one embodiment the grouped cell identity information is transmitted as a broadcast message. A multi RAT, e.g. GERAN/E-UTRAN, capable mobile station receiving such a broadcast message where the IDs are grouped together in tracking area groups is then enabled to determine the neighbouring cells that belong to the same Area. As a result when cell reselection to an E-UTRAN cell is rejected due to that the Tracking Area is not allowed, the mobile station can then be allowed to directly initiate cell reselection to E-UTRAN cells that are not part of the same PCID group, and which thus do not belong to the same tracking area. This in turn results in that no waiting time is needed to initiate a cell reselection towards those cells.
