摘要： The present invention relates to a method of changing a telecommunication channel in a mobile communication system for a given mobile station, which mobile station has a connection in progress, and the connection is provided with a channel on a radio connection between the mobile station and base station system and a telecommunication channel between the base station system and a mobile services switching center. In order to facilitate the changing of the telecommunication channel the method includes putting a new telecommunication channel between the mobile services switching center and the base station system, indicated by the handover message into use for the connection, and connecting the channel used to the new telecommunication channel in such a way that the radio channel remains unchanged irrespective of the change of the telecommunication channel.

摘要： The invention is related to signaling in cellular telecommunication systems, namely to reduction of resources used by signaling. According to the invention, a list of neighbor cell information is communicated to a mobile station in compressed form. Preferably, the neighbor cell information list is transmitted in such a way, that a table reciting parameter values in use by the neighboring cells, and for each of these cells, each value listed in the table is represented by a pointer such as an index to the table. In this way, same parameter values do not need to be repeated for each cell using the same values. The neighbor cell information list can be further compressed by expressing a first frequency parameter value in the normal way, but expressing further frequency parameter values relative to the first, or as in a further embodiment, relative to the previous frequency parameter value. Such ways of representing frequency values allow the use of fewer bits to represent the frequency values.
