Abstract: A call admission method and apparatus are disclosed which maximizes the wireless channel utilization subject to a predetermined bound on the call dropping and packet loss probabilities for variable-bit-rate traffic in a packet switched network. The call admission scheme is stochastic and dynamic, hence it is able to adapt to a wide range of traffic fluctuations and mobility patterns. The call admission scheme disclosed satisfies a set of constraints on call dropping and packet loss probabilities while maintaining high bandwidth utilization.

Abstract: A radio link adapter for wireless transmission of multimedia data through a communication link between a radio access network (RAN) and a mobile station (MS), is provided. The information flow is constantly monitored to determine an information element (IE) type of service requirements and for allocating paired radio link adapters (RLAs) designed to fit the respective type of service requirements. A connection end may be initially established in the RAN or in the MS. An analyser monitors the link, detects the type of service (ToS) required, and dynamically allocates the appropriate type of RLA to the connection. There is no need to recreate the connection when selecting the adapter for transporting various types of services and therefore, the transport of the information flow of a specific ToS over the communication link is optimized, while maintaining the end-to-end quality of service (QoS).
