DETECTION OF SLEEPING CELLS IN A COMMUNICATION NETWORK

摘要

The present invention relates to a kind of networks for establishing the first battery 4a executed in cellular communications networks 1 can not receive uplink radio signal. The embodiment of this method, which comprises determining that, to be not received by from any instruction radio message radio device 5 in predetermined amount of time. The emergence of one unilateral-polar also contains, and in view of the determination, requests second community 4b, 4c or 4d, it is adjacent with first community, it indicates at least one each radio device, be connected to the second community and the first unit can be detected, transmit radio signal. The emergence of one unilateral-polar also contains acquisition on how to receive wireless signal. Determine that the emergence of a unilateral-polar also contains those radio signals and is not successfully received by the first community according to information obtained.
