摘要： The present invention relates to methods, a communication network node and a user equipment for detecting collision of physical cell identities in a communication network system comprising radio base stations each serving at least one cell through which user equipments are moving. Reference signals comprising reference symbols corresponding to a physical cell identity are sent from said radio base stations to said user equipments over a radio interface. Transmission gaps of reference symbols are inserted in the reference signal in order to perform a physical cell identity collision test. The user equipments are arranged to detect if any other radio base station is sending reference symbols corresponding to the same physical cell identity during the transmission gaps. Thereby a physical cell identity collision is detected. The reference symbol transmission gaps are fractionally distributed within said reference signal such that at least some of said reference symbols are unaffected by said reference symbol transmission gaps.

摘要： 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.

摘要： Neighbor cell relation lists are initialized and managed in various ways that are especially beneficial to closed subscriber group (CSG) cells served by CSG base stations. Typically, only a radio terminal belonging to the CSG is permitted to access and receive service from the CSG cell. As a result, information is provided to radio terminals in the cells neighboring the CSG cell that generally indicates that radio terminals are not to report to a respective serving base station signal quality measurements of a signal received from the CSG base station unless the radio terminal is a member of the closed subscriber group for the CSG cell. When a CSG cell is powered-up, it is determined whether the CSG cell has previously been powered-on in the same environment. If so, the neighbor cell relation information for the CSG cell is updated with other network node(s). If not, neighbor cell relations of the CSG cell are initialized. In one example, when a new neighbor cell relation has been added to its neighbor cell relation list, the CSG base station inherits neighbor cell relation list entries from the newly-added neighbor cell.
