ABSTRACT:
A method provides for trunk group satellite switching using a code division multiple access (CDMA) scheme. The method includes receiving inbound satellite beams carrying individually encoded user signals including a plurality of inbound trunk groups, processing and mapping the trunk group elements to a plurality of outbound trunk groups, routing the outbound trunk groups to appropriate outbound satellite beams and transmitting the outbound beams based on common destination parameters. The trunk group switching allows for a reduction of on-board switching complexity, volume, and costs.
