摘要: 在嵌入式系统上实现多链路同时在线目前尚未有较好的解决方法。鉴于此,提出了垂直隔离链路的方法,通过将各拨号链路从驱动层面、PPP层面以及内核层面进行隔离运行,实现多链路同时在线。通过在MPC8315平台的嵌入式linux上实现WCDMA、CDMA 2000、TD-SCDMA等模块的同时在线,验证了提出的链路隔离方法的有效性。

Abstract: Up to now,there is no better multilink simultaneously on-line solution for embedded system.In consideration of the fact,a scheme based on vertical link isolation mechanism is proposed,and each dialing link’s working is isolated from each other in driver layer,PPP layer and kernel layer level.The simultaneously?on-line testing results of WCDMA module,CDMA 2000 module,TD-SCDMA?module and other modules in the embedded linux of MPC8315 platform have confirmed the validity of the proposed scheme.

Key words: embedded PowerPC, multilink, simultaneously on-line, vertical isolation
