Radio base station apparatus and base station controller
First Claim
1. A radio communication method comprising:
- transmitting data and identification information allotted to a radio terminal to the radio terminal from a first and a second radio base stations in a diversity transmission manner; and
transmitting the data and a renewal identification information different from the identification information to the radio terminal from a third base station when the radio terminal moves from an area of the first and second base station to an area of a third base station, whereinthe first radio base station transmits primary information and the second radio base station transmits secondary information, the primary information and the secondary information including same content information, andthe radio terminal in diversity receives the primary information and the secondary information.

Abstract
The invention provides a radio base station apparatus forming a wireless zone in a mobile communication system and to a base station controller performing channel control over a terminal visiting a wireless zone. The radio base station apparatus has an identifying section identifying a particular radio base station that is to maintain a radio channel between the radio base station apparatus and a terminal during a process of diversity handover, a network interface section delivering a signal to a network if a local station is not the particular radio base station, and an inter-office interface section delivering to the network a composite wave of the signal and a signal having arrived and forwarded from the terminal via the radio channel at a radio base station forming a wireless zone adjacent to a wireless zone formed by the local station if the local station is the particular radio base station.
