A wireless cellular telecommunication system with an internet protocol network is provided. The wireless cellular telecommunication system comprises one or more base transceiver stations. The base transceiver stations can selectively provide a radio resource management processing. The radio resource management processing can provide a means for performing an inter-base transceiver station handover. A base transceiver station can communicate with another base transceiver station for the radio resource management processing without assistance from a centralized controller to perform control processing for the base transceiver stations. The base transceiver stations can further selectively provide a radio resource management processing, such as allocating a radio channel, deallocating a radio channel, changing a radio channel, or activating ciphering, without the assistance from a centralized controller to perform control processing for the base transceiver stations.
