In mobile networks each type of services has distinct characteristics and QoS requirement. The important issues in 3-G N/W are to prepare a framework for multi-class services to perform call admission and handoff efficiently. The available call admission control (CAC) and handoff techniques in mobile network have considered only single class of service or have touched value of few classes but not beyond. In this paper we have considered 8 types of services, which are differentiated according to their acceptable delay in transmission, buffering capacity, transmission mode and bit rate. In this approach CAC and handoff issues are resolved by awarding priority number to each cal, which will also resolve issue of collision in CAC and handoff. Performance of proposed framework for CAC and Handoff is evaluated by calculating Call Dropping probability and Call Completion probability.
