ABSTRACT:
A service admission control algorithm for HSUPA and apparatus thereof, and the algorithm describes the access control process for a new service or switching service, i.e. SRNC determines whether the service can be carried using E-DCH based on service property information; the SRNC first checks whether a base station of cell and a terminal user the service makes request for accessing support functions of HUSPA and then checks whether the cell is configured with downlink resources associated with HUSPA if the service can be carried using the E-DCH; if yes, the SRNC determines whether the service is admitted or rejected on the E-DCH based on transmission power resources required for the service and interference on the base station when transmission of the service; the SRNC continues to check whether the service can be admitted on DCH if the service is rejected on the E-DCH; if yes, the service is transmitted using the DCH; if it is rejected, the service is rejected. The present invention can enhance performance of uplink in a system and improve experience for users.
