摘要： An apparatus and method enabling a mobile station to transfer its communications between two dissimilar communications systems, for example, between a first communications system having a time continuous structure, such as a CDMA system, and an alternate communications system having a time discontinuous structure, such as a TDMA system. In one embodiment, the mobile station initiates a time-compressed mode of operation of the first system in which, for a portion of each frame, transmission is disabled, accesses the second system during the disabled periods and specifies to the first system frame structure information of the second system. The first system adjusts the time-compressed mode of operation so that communication with the mobile station occurs during `N` time slots of each frame, the widths and positions of each slot within each frame being set in order to avoid contention with communications to and from the second system.

摘要： A radio communications device is arranged to communicate time divided signals (60 and 70) over first (40) and second (50) time discontinuous systems having first and second frame structures respectively. Switching device (120) switches between communicating signals (60) over the first system (40) during time periods of the first frame structure and communicating signals (70) over the second system (50) during time periods of the second frame structure. Hence over a given period of time the device simultaneously communicates time divided signals over the first (40) and second (50) systems.

摘要： Method, multi-mode base station and computer program product for controlling communication between a user equipment (UE) and the multi-mode base station, the multi-mode base station being arranged to operate as a plurality of cells, the plurality of cells comprising a first cell using a first radio access technology and a second cell using a second radio access technology. The UE is operating in the first cell. Operating conditions of the first and second cells are monitored, and based on the monitored operating conditions of the first and second cells, it is determined that making a handover of the UE to the second cell would provide a performance improvement. In response to determining that making a handover of the UE to the second cell would provide a performance improvement, a handover is made of the UE to the second cell, thereby providing the performance improvement.
