Hybrid Group Paging for Massive Machine-Type Communications in LTE Networks.

In this paper we propose a Hybrid Group Paging scheme to overcome radio access networks (RANs) overload problem due to simultaneous access from massive number of machine-type communications (MTC) devices. Compared to the existing methods, the proposed scheme supports dynamic priority assignment among different sub-groups by combining features from both pull-based and push-based approaches. The performance of the proposed scheme is analyzed using recursive contending user estimation (RCE) method, and shown to agree well with the simulation results.
