Media insertion control method for multimedia broadband CDMA system

The control method includes the following steps: dividing various services with different parameters into two kinds of services of delay high sensitivity and delay low sensitivity and to switch then into system separately for different processing; reserving sufficient resource and switching in the delay high sensitivity service as much as possible; storing all the delay low sensitivity service inbuffer and transmitting those having the same or similar maximum bit error rate service in real time at the same time slot by using reserved bandwidth for delay high sensitivity service; carrying on packet transmission for the delay low sensitivity service with maximum carrier to interference ratio by utilizing the unused resource of the current delay high sensitivity service and carrying on error block judgement for the delay low sensitivity service transmitted in the same time slot with the delay high sensitivity service.
