Embodiment Construction

[0044] In the following description, for purposes of explanation rather than limitation, specific details are set forth, such as particular nodes, functional entities, techniques, protocols, standards, etc., in order to provide an understanding of the described techniques. In other instances, detailed descriptions of well-known methods, devices, techniques, etc. are omitted so as not to obscure the description with unnecessary detail.

[0045] Those skilled in the art will appreciate that block diagrams herein represent conceptual views of illustrative circuitry employing the principles of the technology. Similarly, it will be understood that any flowcharts, state transition diagrams, pseudocode, and the like represent various processes, which may be embodied in a computer-readable medium and thus executed by a computer or processor, whether or not such computer or processor clearly shown.

[0046] The functionality of the various elements including functional blocks labeled ...

Abstract

The technology described automatically resolves cell identity collisions / conflicts in a cellular radio communications network. A detecting node determines that a first cell identifier associated with a first conflicting cell is the same as a second cell identifier associated with a second conflicting cell. One of the first and second conflicting cells is selected to change its cell identifier. A different cell identifier is determined for the selected cell. The different cell identifier is then provided to other cells and preferably to user equipment (UE) terminals without disrupting ongoing UE communications.

Description

technical field [0001] The technical field relates to mobile radio communications involving mobile radio terminals and radio base stations in mobile radio communications systems. Background technique [0002] The Universal Mobile Telecommunications System (UMTS) is a third generation (3G) mobile communication system employing Wideband Code Division Multiple Access (WCDMA) technology standardized within the Third Generation Partnership Project (3GPP). In 3GPP Release 99, the Radio Network Controller (RNC) controls resources and user mobility. Resource control includes admission control, congestion control, and channel switching in response to changing the data rate of the connection. [0003] The Long Term Evolution (LTE) of UMTS is under development of the 3rd Generation Partnership Project (3GPP) which standardized UMTS. A number of technical specifications related to Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Networ...
