Problems solved by technology

[0019] However, a common problem with indoor small cells is that there is little or no overlap between them or between the small cells and the available macrocell coverage outside the building

Embodiment Construction

[0039] Such as figure 1 As shown, the wireless network 100 is composed of several handheld terminals 400 and several base stations 200, 201, 300, 301. Both quantities may evolve continuously as existing base stations / handsets are relocated or new base stations / handsets join or leave the network. Handheld terminals are mobile, and while femtocells can be moved fairly easily, base stations with fixed line backhaul connections are usually in a fixed location, at least when in use. At any one time, a handheld terminal 400 is paired with at most one base station 200, but a base station may be paired with several handheld terminals. Pairing can be formed based on signal strength. Once the signal strength drops below a threshold level, a handover process is initiated. The currently paired base station 200 is responsible for the handover and the handheld terminal measures the signal strength from the other base stations 201, 300 and communicates this information with the paired bas...

Abstract

Method, base station, tangible data carrier, terminal for operating a communication network. Operation of base stations (300a, 300b) in a wireless network with non-overlapping coverage areas is synchronized by taking timing values ​​from mobile units (400) traveling from one coverage area to another. A base station (300b) receiving timing values ​​from mobile units entering its coverage area adjusts its timing values ​​and the timing values ​​of any mobile units in its coverage area to become the same between the base station's existing timing values ​​and the timing indicated by the mobile units Values ​​between the arbitrary mobile units including newly arrived mobile units. The use of median instabilities in the system may result from base stations not being able to communicate directly with each other in real time.

Description

technical field [0001] The present invention relates to a method of operating a mobile communication network, and in particular to a method of providing synchronization data in a mobile communication network. Background technique [0002] figure 1 A schematic diagram of a known mobile communication network 100 is shown. The network includes a plurality of base stations 200 defining macro cells 210 within the network. The mobile terminals 400 within the macro cell 210 can communicate via the base station 200 . Base station 200 will have a backhaul connection (not shown) to allow connection to the Internet and other communication networks. The mobile communication network 100 also includes one or more wireless access points 300 defining smaller cells variously referred to as microcells, picocells and femtocells. The difference between macro, micro, and pico cells is primarily size, but femto cells typically have a different backhaul arrangement than the other types. [00...
