To comply with future communications needs, it is desirable to provide multimedia services at wireless access points. In a wireless multimedia context, resource allocation is crucial because the channel quality varies with time and the network resources are scarce. We address the resource allocation problem in wireless multimedia CDMA (code division multiple access) systems. The objectives are: (1) to develop a wireless multimedia model based on CDMA to provide data rate and quality of service (QoS) on demand and to integrate various traffic types efficiently, and (2) to develop a mathematical programming problem to optimize resource allocation based on a wireless service provider's perspective. In comparison with the previous work, the proposed multimedia model supports a wider range of applications and service qualities, and combines power control, rate allocation and base station assignment with controlled handoff switching and dropped calls in a multi-cell environment
