Packet access mechanisms for cellular radio
John A. Dunlop · Electronics & Communications Engineering Journal · 1993
The paper reviews the findings of work completed in RACE Mobile Telecommunications Project 1043 on the suitability of packet access mechanisms for mixed services in the Universal Mobile Telecommunication System. A first order comparison of random and scheduled access is provided and conditions under which these mechanisms provide an attractive alternative to channel allocation for call duration are specified. It is concluded that packet reservation multiple access (PRMA) is an attractive candidate for mixed services over a range of cell sizes as it can accommodate fixed channel access, reserved channel access and random channel access.
