Abstract
A telecommunications system employing WCDMA technology in a preferred embodiment, utilizes compressed mode techniques to allow a mobile station to take measurements on another frequency in preparation for inter-frequency transfer. The current assumption is that the compressed mode characteristics are controlled by the network, but such control leads to problems when one considers that the slot characteristics are very dependent upon the mobile station characteristics. In the present invention, the control of the slot specifications are dictated by the mobile station to the network and acknowledged by the network to the mobile station. Thereafter, the network informs the WCDMA base station of the slot specifications, which are then imposed from the CDMA base station to the mobile station. Once the mobile station receives the slot from the WCDMA base station, the mobile station is confident that the slot will conform with the characteristics that the mobile station needs in order to make the appropriate measurements.
