摘要: An architecture that adapts low speed mobile data over higher speed digital channels, comprising: Intersystem Link Protocol (ISLP) framing structure having ISLP service data units; circuit-mode data carried by the ISLP service data units; a set of call processing and handoff messages, said set including Assignment Request, Assignment Complete, Handoff Required, Handoff Request, and Handoff Request Acknowledge; an indicator incorporated into said set; and digital channels responsive to said indicator to transport the circuit-mode data via the ISLP service data units over an A-interface between a base station (BS) and a mobile switching center (MSC).
