Abstract
A communications system comprising a first plurality of cells operating in accordance with a first mode and a second plurality of cells operating in accordance with a second mode, each of said cells being served by a respective first station, at least one second station arranged to establish a connection with at least one first station, said at least one second station being associated with said first plurality of cells or said second plurality of cells during said connection and means for determining which plurality of cells said second station is associated after said connection has been completed.
Claims46
A communications system comprising a first plurality of cells operating in accordance with a first mode and a second plurality of cells operating in accordance with a second mode, each of said cells being served by a respective first station, at least one second station arranged to establish a connection with at least one first station, said at least one second station being associated with said first plurality of cells or said second plurality of cells during said connection and means arranged to send information to said second station for selecting which plurality of cells said second station is associated after said connection has been completed.
A system as claimed in any preceding claim, wherein the selecting means is arranged to provide the same statistical parameter to a plurality of second stations.
A system as claimed in any preceding claim, wherein an idle mode occurs after a connection has been completed.
A system as claimed in any preceding claim, wherein said first and second plurality of cells are on different frequency bands.
A system as claimed in any preceding claim, wherein said first and second plurality of cells use different radio access technology.
A system as claimed in any preceding claim, wherein said first and said second plurality of cells are on different location areas.
A system as claimed in any preceding claim, wherein said first and second plurality of cells are on different networks
A communications system as claimed in any preceding claim, wherein said second station is arranged to select a cell of the selected plurality of cells.
A communications system as claimed in claim any preceding claim, wherein said second station uses measurements made during the connection to select a cell.
A communications system as claimed in any preceding claim, wherein said communications system is a wireless communications system.
A communication system as claimed in any preceding claim, wherein said first station is a base station.
A communications system as claimed in any preceding claim, wherein said at least one second station is a mobile station.
A communications system as claimed in any preceding claim, wherein said first and second plurality of cells use first and second standards respectively.
A communications system as claimed in any preceding claim, wherein said communications system comprises at least one network to which said second station is attachable, said first stations being part of said at least one network, wherein said at least one network is arranged to determine the plurality of cells to which said second station is to be associated.
A communications system comprising a first plurality of cells operating in accordance with a first mode and a second plurality of cells operating in accordance with a second mode, each of said cells being served by a respective first station, at least one second station arranged to establish a connection with at least one first station, and means arranged to send information to said second station for selecting which at least one cell said second station is associated when said second station is idle.
A communications system comprising a first plurality of cells operating in accordance with a first mode and a second plurality of cells operating in accordance with a second mode, each of said cells being served by a respective first station, at least one second station arranged to establish a connection with at least one first station, said at least one second station being associated with said first plurality of cells or said second plurality of cells during said connection and means arranged to send information to said second station for selecting if the second station is associated with at least one cell operating in accordance with the first mode or at least one cell operating in accordance with the second mode, after said connection has been completed.
A communications method for a communications system comprising a first plurality of cells operating in accordance with a first mode and a second plurality of cells operating in accordance with a second mode, each of said cells being served by a respective first station, said method comprising the steps of:
- establishing a connection between a second station and at least one first station, said second station being arranged to receive information for selecting if the second station is to be associated with a cell operating in accordance with the first mode or the second mode;
- releasing the connection between the first and second station;
- and
- selecting if the second station is to be associated with a cell operating in accordance with the first mode or the second mode.
A communications system method for a communications system comprising a plurality of cells, each of said cells being served by a respective first station and at least one second station, said method comprising the steps of:
- establishing a connection between at least one first station and a second station, said at least one second station being associated with a first cell during said connection;
- and
- means arranged to send information to said second station for selecting which cell said second station is associated with in idle mode after said connection has been completed.
A network element of a communications system comprising a plurality of cells, each of said cells being served by a respective first station, at least one second station arranged to establish a connection with at least one first station, said at least one second station being associated with a first cell during said connection, said network element comprising means arranged to send information to said second station for selecting which cell said second station is associated with in idle mode after said connection has been completed.
A first station of a communications system comprising a plurality of cells, each of said cells being served by a first station, at least one second station arranged to establish a connection with at least one first station, said at least one second station being associated with a first cell during said connection, said first station comprising means arranged to send information to said second station for selecting which cell said second station is associated with in idle mode after said connection has been completed.
A second station of a communications system comprising a first plurality of cells arranged to operate in accordance with a first mode and a second plurality of cells arranged to operate in accordance with a second mode, each of said cells being served by a first station, said second station arranged to establish a connection with at least one first station, said second station being associated with a first cell during said connection, said second station being arranged to receive information for selecting which plurality of cells said second station is associated.
A communications system comprising
- a plurality of cells, each of said cells being served by a respective first station;
- at least one second station arranged to establish a connection with at least one first station;
- said at least one second station being associated with a first cell during said connection;
- and
- means arranged to send information to said second station for selecting which cell said second station is associated with in idle mode after said connection has been completed.
