Patent ID: 8416798

Claim:
A femtocell in communication with a centralized server, the femtocell comprising a processor, a storage system, and one or more programs, wherein the one or more programs are stored in the storage system and operable to be executed by the processor, the femtocell comprising: a connecting module operable to connect to the Internet and obtain an available frequency range of a telecom operator via the Internet; a detection module operable to detect communication parameters of neighboring femtocells and macrocells according to the obtained available frequency range; a generating module operable to randomly generate a set of communication parameters suitable for the femtocell according to the detected communication parameters; a confirmation module operable to require the centralized server to confirm an availability or an unavailability of the set of generated communication parameters, wherein the availability of the set of generated communication parameters indicates that the set of generated communication parameters is allowed by the centralized server and has not been employed by other femtocells and macrocells that have generated the communication parameters via the centralized server and the unavailability of the set of generated communication parameters indicates that the set of generated communication parameters is not allowed by the centralized server or has been employed by the other femtocells and the macrocells that have generated the communication parameters via the centralized server; and a communication module operable to use the generated communication parameters to communicate with a communication terminal if the set of generated communication parameters is available.
