Abstract
In order to resolve congestion of the random access channel (RAC) caused by UE’s concentrated access to the network in the process of group paging, this paper introduces the pre-backoff algorithm on the basis of studying MTC service characteristics to the group paging mechanism, and proposes the analysis model based on the group paging mechanism with pre-backoff. In the group paging mechanism with pre-backoff, when monitoring results indicate ongoing of group paging, all UE within the group, before access, will implement pre-backoff, and through pre-backoff, different pieces of UE are evenly distributed to a period of access time to alleviate collisions and conflicts resulted from concentrated access. Simulation results of three performance indexes, including the probability of conflict, probability of successful access and delay of average access, are used to analyze and verify the validity of the analysis model based on the group paging mechanism with pre-backoff.
