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.
