Femtocell and parameter generating method thereof
A femtocell in communication with a centralized server and a communication terminal obtains an available frequency range of a telecom operator via the Internet, detects communication parameters of neighboring femtocells and macrocells according to the obtained available frequency range, and randomly generates a set of communication parameters suitable for the femtocell according to the detected communication parameters. The femtocell further requires the centralized server to confirm availability of the set of generated communication parameters, and employs the generated communication parameters to communicate with the communication terminal if the set of generated communication parameters is available.
1. 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:
