-SIM VAMOS SYSTEM AND METHODS FOR INCREASING NETWORK EFFICIENCY USING VAMOS CHANNELS ON A MULTI-SIM DEVICE

摘要

A method is provided for optimizing voice over adaptive multi-user channels on one slot (VAMOS) communications by allocating up to four independent communications to the same device and assigning them to sub-channels of the same VAMOS channel. A VAMOS-capable multi-SIM wireless device, such as a dual-SIM dual active (DSDA) device, may have up to four concurrently active calls in the same access network. When assigned to the same VAMOS channel, up to four active calls may be merged to utilize the same radio in the device.
