FREQUENCY HOPPING METHOD IN GERAN/VAMOS SYSTEM

摘要

A frequency hopping method in GERAN/VAMOS system, comprising steps of: for a user in VAMOS subchannel 1, calculating a frequency used in each frame in accordance with a frequency hopping solution in the GSM standard; for a user in VAMOS subchannel 2, changing its own MAIO value in each frame or every two or more frames, and calculating a frequency used in current frame in combination with a hopping sequence number HSN and a current frame number. With the method of this invention, frequency hopping solution is changed only for the user in subchannel 2, while frequency hopping solution for the user in subchannel 1 is not changed. Frequency diversity and customer diversity are realized without causing additional computational complexity.
