A multiplexing method for Voice services over Adaptive Multi-user Channels on One Slot, VAMOS, executed by a multiplexing apparatus, comprising: sorting out one or more multiplexing resource pools according to a multiplexing parameter combination; wherein the multiplexing parameter combination is a combination (RXLEV, RXQUAL) of received signal level, RXLEV, and received signal quality, RXQUAL; further wherein threshold values corresponding to the received signal level, RXLEV, comprise: a low level threshold, Lev_thLow, and a high level threshold, Lev_thHigh; and threshold values corresponding to the received signal quality, RXQUAL, comprise: a low quality threshold, Qual_thLow, and a high quality threshold, Qual_thHigh; ranking multiplexing users in the one or more multiplexing resource pools according to a value parameter; wherein the value parameter is a received signal level, RXLEV or a received signal quality, RXQUAL, or a sub channel power imbalance ratio, SCPIR; and carrying out multiplexing on multiplexing users of which ranks are adjacent according to a ranking result; wherein the step of sorting out one or more multiplexing resource pools according to a multiplexing parameter combination comprises: first constructing a multiplexing space by taking each multiplexing parameter in the multiplexing parameter combination as a coordinate axes to form a reference coordinate system, and then dividing the multiplexing space into a plurality of resource pools by using the thresholds values corresponding to each multiplexing parameter in the multiplexing parameter combination; sorting out a resource pool of which a power is required to be down-regulated or to be kept unchanged from the plurality of resource pools as a strong signal resource pool; and acquiring an average multiplexing parameter value combination of steady state users which support the VAMOS, determining the resource pool of the plurality of resource pools to which each steady state user belongs according to the average multiplexing parameter value combination, and constructing, as a multiplexing resource pool, the steady state users which belong to a resource pool of the resource pools sorted out as a strong signal resource pool of which a power is required to be down-regulated or to be kept unchanged. sorting out one or more multiplexing resource pools according to a multiplexing parameter combination;
