<p>A mobile communications system includes a plurality of cell segments each allocated primary carriers to carry circuit-switched traffic and packet data carriers for carrying packet-switched traffic. The packet data carriers include two sets of carriers, a main set of carriers (F1, F2, or F3) and a secondary set of carriers (F4, F5, and F6). The main packet data carriers (F1, F2, and F3) are allocated to corresponding cell segments. The secondary carriers (F4, F5, and F6) are allocated to high capacity segments, which may be segments having high bursty traffic or segments in which a hierarchical cell structure is implemented. For high bursty cell segments, the main carriers (F1, F2, and F3) are used to carry control signaling for performing selection or reselection. However, in such high bursty cell segments, the secondary carriers (F4, F5, and F6) are not used for performing cell segment selection or reselection.</p> |
