Abstract In the paper, we use zone concepts, and also consider multiple‐bunch in a TD‐CDMA mobile network. In the multiple‐bunch environment, we need a synchronization mechanism to avoid inter‐RNC interferences. Here, we use anInformed‐ofmessage to transmit local resource allocation results to other neighbouring RNCs through a high‐speed network. Thus, inter‐RNC interferences can be avoided and the global resource allocation can be made with the message passing. Within the resource allocation algorithm, we also findmaximal compatible cliquesto achieve the best resource utilization, using the graph algorithm finding maximal cliques in graph theory. Through the simulation, we found that the SRU classification usingConservativestrategy matching the SRU allocation usingAggressivestrategy has the best performance among all combinations.
