Reducing call setup time is a general objective that is unrelated to radio technology, be it 2G, 2.5G, 3G or beyond. However, the requirement is more stringent for dispatch services (push-to-talk), which, in many cases, are mobile-to-mobile calls, thus involving paging. Since most of the mobile stations monitor paging channels in slotted mode to preserve battery life, the length of the paging slotting cycle may easily become a significant component of the overall call setup time. The obvious solution, reducing the length of the slotting cycle, comes at the price of reduced battery life. This paper proposes a very simple, yet effective and practical way, to reduce the paging slotting cycle in circumstances when power is not at a premium.
