Dual-mode reconfigurable base station and SCA-based service mode switching method thereof

A dual-mode reconfigurable base station system (RBSS) operating and switching between a first mode or a second mode in accordance to respective first and second mode applied requests, the RBSS coupled to a user terminal through a wireless network and coupled to a reconfigurable base station manager (RBSM) through an Ethernet, the RBSS comprising:

• an RF subsystem comprising at least one first processor for performing wireless communication with the user terminal;
• a base band subsystem comprising at least one second processor for performing wireless traffic call processes;
• and
• a base station interaction subsystem comprising a base station controller (BSC) for controlling internal communication within the RBSM for controlling the RBSS in a first mode RBSS, for controlling the RBSS in a second mode, and for performing a dual-mode system reconfiguration of the RBSS,
• wherein the RBSM stores a common component file (CCF) which comprises a common portion of first and second service mode software (1stSMS and 2ndSMS, respectively) which is commonly used for both the first and second modes, the RBSM also stores a non-common portion of the 1stSMS which is non-common with the 2ndSMS In which the non-common portion of the 1stSMS is used along with the CCF to control the RBSS in the first mode, and the RBSM also stores a non-common portion of the 2ndSMS which is non-common with the 1stSMS in which the non-common portion of the 2ndSMS is used along with the CCF to control the RBSS in the second mode;
• and
• the BSC downloads and installs the CCF only once from the RBSM,
• the BSC downloads and installs the non-common portion of the first service mode software to use along with the once installed CCF to drive the RBSS in the first mode when the first mode applied request is initiated by the user terminal,
• the BSC downloads and installs the non-common portion of the second service mode software to use along with the once installed CCF to drive the RBSS in the second mode when the second mode applied request is initiated by the user terminal.
