A CDMA system according to an embodiment of the invention employs a technique for power optimized user loading that obtains a desired allocation of different radio configuration calls. The technique takes advantage of the relatively low power requirements of RC3 calls for low load conditions, while increasing the number of RC4 calls for high load conditions. As the load increases, the system determines a target combination of RC3 and RC4 calls based upon the current average power per link measurements for RC3 and RC4 calls, and based upon the power limitations of the system. The technique strives to maximize the capacity of the system while maintaining operation below the overall power limit.

System and method for managing CDMA communication system capacity using power-based metrics

A CDMA system according to an embodiment of the invention employs a technique for power optimized user loading that obtains a desired allocation of different radio configuration calls. The technique takes advantage of the relatively low power requirements of RC3 calls for low load conditions, while increasing the number of RC4 calls for high load conditions. As the load increases, the percentage of RC4 calls increases while the percentage of RC3 calls decreases. The technique strives to minimize overall power consumption in the system for all call load conditions, by maximizing the number of RC3 calls at any given time while keeping Walsh code resources available for both new calls and hand-in traffic.

A multicast message is transmitted from an originating subscriber unit (,, FIG.,) through a network of satellite communications nodes (,, and,) to a plurality of receiving subscriber units (,, and,). Each message is distributed through the network of satellite communications nodes (,, and,) and replicated at the node nearest to the receiving subscriber unit. Receiving subscriber units (,, and,) are mapped into geographic cells which allows a single multicast transmission to be transmitted from the satellite communications node to those subscriber units within the same geographic cell. Multicast groups and membership rules are established by the originating subscriber unit (,) through a service provider (,). A multicast session manager (,) manages the multicast session.
