Method of and equipment for performing radio communication in a plurality of radio communication environments
First Claim
1. A method of performing radio communication between a fixed radio access unit in a cellular radio communication system and a remote portable radio telecommunication unit that roams between areas having different radio communication characteristics, said method comprising:
- detecting by the fixed radio access unit, that the portable unit has entered a new area having different radio communication characteristics than a previous area where the portable unit was operating; and
sending a message from the fixed radio access unit to the portable unit providing the portable unit with information related to operational parameter settings corresponding to the radio communication characteristics in the new area that the portable unit has entered, said operational parameter settings including at least one of channel scan rate, channel selection rate, and handover threshold signal strength, said operational parameter settings causing the portable unit to change its operating characteristics in a manner that optimizes radio communication performance of the portable unit within the new area where the portable unit is operating.

Abstract
A method of and equipment for performing radio communication (7) between a fixed radio access unit (5, 10, 13, 15) and a remote portable radio telecommunication unit (8) arranged for operating in accordance with a predetermined radio communication standard, such as Digital Enhanced Cordless Telecommunications (DECT), in a plurality of radio communication environments such as in the home (2), in the office (3) and/or in the public domain (4). For each radio environment (2, 3, 4) operational parmeter settings are obtained associated with system operation efficiency and communication quality of a particular environment (2, 3, 4). Radio communication (7) is performed with the operational parameter settings selected in accordance with the applicable radio environment (2, 3, 4).
