Abstract:
1. A method of letting a temporary radio base station (RBS), gain and maintain control of traffic to and from a targeted radio base station in a wireless cellular telecommunications system, said system comprising a plurality of RBSs for routing traffic to and from user terminals in the system, each RBS controlling the traffic to and from a certain cell within the system, a number of said plurality of RBSs in the system each transmitting an identity signal and a list of candidate frequencies for use by user terminals when switching RBS, the method comprising the following steps: positioning said temporary RBS in or adjacent to the cell of the targeted RBS, the temporary RBS transmitting on one of the frequencies in the candidate list broadcast by the targeted RBS, setting the transmissions of the temporary RBS to such a power level that traffic to and from user terminals in the cell of the targeted RBS will be transferred to the temporary RBS, the temporary RBS transmitting an identity signal which is the same as that of the RBS whose frequency the temporary RBS transmits on and transmitting a list of candidate frequencies, the list being such that user terminals whose traffic has been transferred to the temporary RBS cannot find signals with sufficient strength on any of the candidate frequencies in the vicinity of the cell of the targeted RBS.
