    Abstract: The present invention is to a method of monitoring state of a telecommunications network, and to a telecommunications network comprising a complexity determinator. The network comprises a plurality of nodes, each node is at a time on one of a number of node states dependent upon a predetermined set of rules and local conditions at the node. The method/ complexity determinator comprises determining the value of a parameter dependent upon entropy (which is a measure of how random the system behaviour is) of the node states in the network. The present invention provides entropy based complexity measurement for behaviour analysis of self organising telecommunications networks. Specifically, the application of the entropy-based complexity measure in telecommunications networks is useful to examine behaviours of localised distributed algorithms (LDA), (operative at Base Station levels and uses only local information and simple local rules at the Base Stations). The behaviour of self-organising LDA networks can thus be investigated to determine network-wide trends. The complexity measurement is used for setting the size of the Base Station cells.

    Abstract: A wireless communication technique provides mobility for a mobile station (52) to communicate with an overlay network device (40), which is within a coverage area (34) of an underlay network device (24), when the mobile station (52) is within a coverage area (42) of both devices. The overlay network device (40) broadcasts at least two downlink channels. A cell code (e.g., a scrambling code or pseudo noise offset) of a first one of the downlink channels identifies an overlay network device (40) exclusively. The mobile station (52) can detect the first downlink channel responsive to an indication of the exclusive cell code from the underlay network device. A second one of the downlink channels allows for subsequent, ongoing communications between the mobile station and the overlay network device.

    Abstract: A communications system (1) includes an underlay network (2), which a cellular communications network implemented using UMTS technology, and an overlay home cell (8) set up by a user using a base station router (7), or other similar access device. A call may be transferred from the home cell (8) to a cell of the underlay network (2) and vice versa. If these operate at different tariffs, the user may find that handover between them results in extra charges for an on-going call. The user terminal (10) is enabled so as to allow the user to determine if handover should be performed, and thus retain control of costs incurred in making a call. The user terminal (10) may give an alert if there is a risk of imminent handover, allowing the user to take avoiding action if desired, or the user may configure preferences to control under what conditions handover may be performed.

    Abstract: A transmit power control technique within a wireless communication system includes adjusting a transmit power used by a picocell base station unit based upon a position of the picocell within a macrocell. When a picocell base station unit is located relatively close to a macrocell base station or center of the macrocell, the transmit power of the picocell base station unit is increased to avoid downlink interference from the macrocell base station for mobile stations communicating within the picocell. When a picocell base station unit is located relatively close to an edge of a macrocell, the transmit power of the picocell base station is decreased to avoid interference caused by the picocell base station unit for mobile stations communicating within the macrocell in the vicinity of the picocell. In a disclosed example determined downlink interference levels provide an indication of the position of the picocell within the macrocell and provide an indication of how to automatically adjust the transmit power of the picocell base station unit.
