Analyzing and optimizing the Qo S about packet service

is one of the most main staff for the network optimization in Telecommunications Operator. The delay of packet service is one of the most important KPI about Qo S

and optimizing the delay of packet service can improve the Qo S of consumer. The paper analyze the signal of packet service in TD-SCDMA

and combine with the actual test

then prove that reducing the delay of RAB process will improve the Qo S about packet service

and give the method to reduce the delay of RAB process.
