Abstract: A method for a Digital Wireless Office System (DWOS) to establish and update a public neighbor cell list for roaming mobile stations is disclosed. Transmissions of the base stations of public cells are scanned by DWOS scanners. Information from the Digital Control Channels and Broadcast Control Channels is used in formulating the list.

Abstract: A method for optimizing the use of channels, the changing of channels and handover procedures in a mobile telecommunications system for instance, wherein parameters belonging to the mobile telecommunications system generate the load values for the connections via different channels/base stations between subscribers in a public telephone network and mobile stations in the mobile telecommunications systems. Different kinds of parameters can be compared directly by means of the load values which are combined to provide a total load value for each connection. A first total load value is generated for a connection set-up between one of the subscribers and one of the mobile stations. The total load values for the connection are estimated for alternative channels/base stations and these total load values are compared with the first total load value. The system changes to the channel/base station that has the most favorable load value, on the basis of the comparison.
