Embodiment Construction

[0015] exist figure 1 In , a femtocell 2 coupled to the network at 4 is shown. This will be a hardwired connection. The femtocell comprises a femtocell gateway 6 and an access point 8 coupled by a broadband connection 10 . The access point is coupled with a transmitter / receiver 12 that transmits and receives signals to / from user equipment within range over a short distance. The user device may be, for example, a mobile phone 14 or a data card 16 attached to a laptop computer 18 . A user equipment that comes within range of a femtocell access point may communicate directly with the access point (if it is authorized to do so) and do so in preference to the macrocell in which it is located.

[0016] exist figure 2 , a schematic diagram of a macro cell 20 is shown. There is a base station 22 which transmits and receives signals to / from user equipment located therein. There are also multiple femtocells 2 within the macrocell. These may include clusters of femtocells 2 as ma...

Abstract

A method for instigating a location / routing area update procedure (LAU / RAU) when a piece of user equipment (UE) reselects its communication base station from a macro base station to a shorter range base station positioned within a macro cell of the macro base station is disclosed. The method comprises the steps of establishing a radio resource control connection between the UE and the shorter range base station; registering the UE with the shorter range base station; assigning location area code data (LAC) and routing area code data (RAC) from the shorter range base station to the UE; whereinthe LAC and RAC data are the same data as the LAC and RAC data provided to the UE by the macro cell base station, whereby the UE does not perform a LAU / RAU procedure when it moves out of range of theshorter range base station and recommences communication with the macro base station.

Description

technical field [0001] The present invention relates to location routing area update procedures (LAU / RAU) for mobile communication systems, and in particular to the method used when a user equipment (UE) moves between different types of macro cells and access points the process of. Background technique [0002] Mobile communication systems operate on a cellular basis, where transmitting and receiving base stations coupled to the network provide transmission and reception to UEs, such as mobile phones, in various cells in the network. A number of cells together form a location / routing area. A location area always contains more cells than a routing area. When a user equipment such as a mobile phone moves between areas, there is a location / routing area update procedure (if the new cell is in another location / routing area) where the user equipment selects a cell for receiving and sending to. new cell and end transmission and reception in another area. These base stations and...
