The present invention relates to a method and an apparatus for providing each terminal (t.sub.1, t.sub.2, t) in a network (n) with an adapted location area (HA.sub.t1, HA.sub.t2, FA.sub.s, FA.sub.pt), customised to the long term or short term historical movements or behaviour of the terminal (t.sub.1, t.sub.2, t) in the network (n). The terminal (t.sub.1, t.sub.2, t) can enter three different modes; session mode, packet mode and transaction mode, which controls what kind of location area (HA.sub.t1, HA.sub.t2, FA.sub.s, FA.sub.pt) the terminal (t.sub.1, t.sub.2, t) should use. The types of location areas are a home location area (HA.sub.t1, HA.sub.t2), based on the long term historical movements of the terminal (t.sub.1, t.sub.2, t) and used when the terminal (t.sub.1, t.sub.2, t) is located inside a home area constituting the normal mobility pattern of the terminal in the network (n), a session mode-fast adaptive location area (FA.sub.s), used when the terminal (t.sub.1, t.sub.2, t) enters the session mode and is located outside the home area, and a packet mode/transaction mode-fast adaptive location area (FA.sub.pt), used for burstlike traffic when the terminal (t.sub.1, t.sub.2, t) enters the packet mode or the transaction mode. |

DETAILED DESCRIPTION The problem dealt with by the present invention is to minimise the radio resource consumption caused by paging, location updating and periodic registration of a radio mobile terminal, also called terminal or mobile terminal, in a communication network, also called network or cellular network.
Another problem is to distribute the load caused by location updating of the terminal in the network more evenly between cells in the network.
One intention of the invention is thus to minimise the radio resource consumption caused by paging, location updating and periodic registration of a terminal in the network.
Another intention is to distribute the load caused by location updating more evenly between cells in the network.
The problem is solved essentially by providing each terminal in a network with an adapted location area, customised to the long term or the short term historical movements or behaviour of the terminal in the network.
The invention adapts algorithms, which controls the shape, the position and the size of the location area, wherein the location area continuously adapts to the behaviour of the user of the terminal.
More specifically, the problem is solved in the following manner.
The terminal and the network use three different kinds of modes according to the invention.
These modes in turn control what kind of location area the terminal should use.
The different modes are called session mode, packet mode and transaction mode.
For a specific terminal in the network, the network uses a mode corresponding to the same type of mode as used by the specific terminal.
The duration of the active periods of a communication, also called traffic, sent between the terminal and the corresponding basestation in the network and the duration of the silent periods in between the active periods determines according to the invention what type of mode the terminal and the network should be in.
Three main types of location areas are used according to the invention.
The first type of location area is a home location area, which constitute the normal mobility pattern of the terminal in the network
