A radio network controller and radio network controller assembly

Abstract

It is presented a radio network controller assembly for controlling base stations. The radio network controller assembly comprises: a plurality of unit radio network controllers, wherein each unit radio network controller comprises: a set of external interfaces configured for interaction with a core network, base stations and other radio network controllers; and a set of internal interfaces, distinct from the set of external interfaces, configured at least for interaction with peer unit radio network controllers belonging to the radio network controller assembly. The radio network assembly further comprises a database arranged to store configuration data comprising mappings of each base station to one of the plurality of unit radio network controllers. The radio network controller assembly is arranged to use the set of external interfaces for communication with the plurality of base stations, the core network and other radio network controllers external to the radio network controller assembly.

Description

technical field [0001] The invention relates to a radio network controller in a mobile communication network. Background technique [0002] A Radio Network Controller (RNC) is a node used in a mobile communication network to control several base stations. Base stations are also known in various standards as base transceiver stations, node base stations (node ​​B) or enhanced node base stations (enhanced node B). Each base station controls at least one radio cell within which a mobile communication device gains access to a mobile communication network. An RNC is typically provided with interfaces to interact with its base stations, other RNCs, and the core network of the mobile communication network. [0003] In many respects, it is preferable to have a single control node, such as an RNC, controlling a large number of base stations. Typically, the most important aspects are node and network management efficiency, eg less border maintenance, easy network expansion, reduced...

Problems solved by technology

[0004] However, building and managing a wireless network with large control nodes is also a challenge due to the complex control nodes, the possible expansion allowed by the limited initial design of the nodes, the complex hardware generation offsets, and the very large failure area in case of node failure. complicated
