This thesis proposes an architecture for wireless services in telemedicine.The scenario visualized is of an ambulance carrying a traumapatient and sending medical data (video, ultrasound, ECG) to itscorresponding hospital. It needs to know in advance the approximatebandwidth available to it after every handoff.This thesis attempts to solve this problem with Intelligent Network signalling which aids fast implementation of new services. It isassumed that the ambulance uses a TDMA(GSM/PACS) based phone with multiple slotconnection capability. New signalling procedures are suggested whichattempt to provide this service with minimum delay and load.Some slot allocation schemes implemented at the base stations aredesigned and evaluated. Buffer management schemesat the mobile to manage packets from various data streams are proposed andcompared. All queuing systems are simulated in Opnet.
