Title: Communicating method
Inventor: QI BI
IPC: H04W36/30
Filed: 2001-10-09
Abstract: PROBLEM TO BE SOLVED: To provide a method for permitting an MS(mobile station) to automatically resume a call when the MS loses communications with a base station(BS). SOLUTION: The MS monitors signals from other BSs while it communicates with a BS. The signals are measured and the strength of the signals received from BSs in the reception-possible area of the MS is decided. When MS loses a traffic channel being used for communicating voice or data with the BS, the MS tries a contact with another BS. The BS that the MS selects to contact has the strongest signal which the MS monitored previously. When the MS makes contact with the new BS, the MS requests a hand-off from the BSs with which contact is lost to another BS supplying communication services to the MS. New traffic channels are allocated to the MS with BSs on the basis of the MS request and the measurement value of the signal strength of other BSs which were included in the hand-off request of the MS.
