| Abstract: | This paper describes the research on a new technology of wireless IP call,that is,GPRS-IP call,which is based on GPRS access and can switch the voice between the GPRS net and the GSM net so that the ongoing call can be switched seamlessly from the packet-switched net to the traditional circuit-switched net.This paper analyzes the switching method and describes the problem of bandwidth demand,the packet delay,the jitter,the packet loss which would affect the quality of IP call based on GPRS wireless access,a... |
