Abstract
An arrangement for effecting call handoffs in a wireless communications system (FIG. 1 ) in a substantially glitchless manner. The arrangement relies on the mobile terminal (4) that is involved in a handoff to trigger the handoff by transmitting a handoff coordination signal simultaneously to the base stations (1, 2) that are involved in the handoff. The base stations receive the signal substantially simultaneously, and in response the base station that has been serving the mobile terminal's call ceases to do so while the base station that is henceforth to serve the mobile terminal's call commences to do so at the same instant in time.
