Multifrekvensadgangskontrol ved hjælp af integreret multiradioadgangsteknologi

摘要

A node of a multi-radio access technology (RAT) system acquires resource status information associated with each RAT of the multi-RAT system. The resource status information of the RATs of the multi-RAT system can be acquired by sniffing higher layer protocol information pertaining to call setup requests and/or call terminated messages. The node further maintains a flag representing overall resource availability associated with the RATs of the multi-RAT system, based on the acquired resource status information, for use in admission control and/or load balancing. The flag is associated with a pre-defined set of overall resource availability states of the multi-RAT system, where the availability states are defined in terms of admission control decisions. The availability states comprise at least one of the following admission control decisions: i) unconditional acceptance of all services; ii) conditional acceptance of broadband guaranteed bit rate (GBR) services and unconditional acceptance of all other services; iii) conditional acceptance of broadband GBR services, conditional acceptance of narrowband GBR services, and unconditional acceptance of other services; or iv) unconditional rejection of all services.
