1) layered carrier access
载波分层接入
1.
Enhanced General Packet Radio Service (EGPRS) is sensitivity to the wireless characteristic, assigned by layered carrier access method, EGPRS can be achieved better transition rate, which will improve the experience of subscribers greatly.
EGPRS对无线信道的物理特征较为敏感,通过无线载波分层接入技术为EGPRS业务指定业务信道,提高了EGPRS业务的传输速率,大幅提高了用户感知,同时由于该技术为不同业务提供差异化服务,为不同种类的业务优化也具有指导意义。
