ABSTRACT:
A system and method in accordance with the present invention reduce the amount of data that is stalled in a source Node B after a serving HS-DSCH cell change in a communication system that includes a serving RNC and at least one Node B. In a first embodiment, the RNC temporarily suspends data transmissions from the RNC to the Node B. In a second embodiment, the activation time is used in data scheduling. In a third embodiment, a more robust MCS level is selected. In a fourth embodiment flow control is employed for the data transmitted between the RNC and the Node B.
