PURPOSE: To enhance a successful rate of hand-over even under an environment where the electric field strength of a ratio wave sent from a wireless base station being a hand-over source is weaker than the electric field strength of a radio wave sent from a wireless base station being a hand-over destination due to the effect of an obstacle or the like. CONSTITUTION: In the code division multiple access communication system, an outgoing channel is provided with a common speech channel capable of transmitting information required for hand-over to a mobile device, and when a mobile device moves from an area of one wireless base station to an area of other wireless base station, the source base station transmits information required for hand-over through the common speech channel when the mobile device moves from the area of the wireless base station to the area of the other wireless base station. |
