Abstract
The invention discloses a spectrum sharing method, and relates to the technical field of communications. The method effectively protects the stability of services on a GSM (Global System for Mobile Communications) and avoids insufficient or excessive protection on the GSM. The method comprises the steps of collecting statistics on the traffic sum C on a carrier F used by the GSM currently; when the traffic sum is greater than a threshold value, adding protection resource blocks for an LTE (Long Term Evolution) carrier to the carrier of the LTE adjacent to the GSM till the protection bandwidth between the adjacent carriers of the LTE and the GSM reaches a standard specified value or satisfies the condition that C/F*F1 is greater than or equal to the threshold value, wherein F1 is the quantity of carriers used by the GSM after the protection resource blocks are added. The method is suitable for a backset spectrum allocation process from the GSM to the LTE.
