System and methods for increasing network efficiency using VAMOS channels on a multi-SIM device

摘要

Methods are provided that optimize Voice over Adaptive Multi-user channels on One Slot (VAMOS) communications by recognizing that up to four independent communications are located on 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 simultaneous active calls on the same access network. When assigned to the same VAMOS channel, the up to four active calls may be merged to all use the same radio on the device.

1. A method of allocating physical channels by a base station in a wireless communications network, comprising:
receiving, from a first radio frequency (RF) resource associated with a first active communications session, information indicating that the first RF resource is capable of supporting Voice services over Adaptive Multi-user channels on One Slot (VAMOS) communications; receiving, from a second RF resource associated with a second active communications session, information indicating that the second RF resource is capable of supporting VAMOS communications; determining whether the first RF resource and the second RF resource are co-located within a single wireless device; assigning a VAMOS channel to the first and second active communications sessions in response to determining that the first RF resource and the second RF resource are co-located within a single wireless device; multiplexing the first active communications session and the second active communications session onto sub-channels of the assigned VAMOS channel; and transmitting the first and second active communications sessions simultaneously on the assigned VAMOS channel such that data is simultaneously received by the first RF resource and the second RF resource.
