Dynamic Page Pattern Detection and Validation for Cellular Networks in DSDS Device
Rushabh Avinash Vakharia, Lalit Pathak · 2021
In Cellular Networks like 5G, when a user uses a Dual Sim Dual Standby (DSDS) device, there are high changes of Page Occasion (PO) collision across both the protocol stacks (PS) of two Subscriber Identity Modules (SIM). During such scenarios, an arbitrator module normally tries to resolve such collision using methods like round robin, alternate, weighted round robin etc. Using these approaches, the arbitrator cannot avoid the page miss very efficiently, as it is unaware of the repeat pattern of the network page. In this paper we propose an efficient way which can enhance the performance of resolution of the page conflicts by trying to determine a probabilistic network page repeat pattern dynamically. The approach relies on the learning based on the page reception of the User Equipment (UE) over the time and determine the probabilistic page repeat pattern. This newly determined page repeat pattern will be utilized by the arbitrator to resolve conflicts in cases when the paging occasion of both stack fall nearby or overlap. As the page repeat pattern of network is dynamic in nature, in this paper we also try to address a validation mechanism which is continuous and tries to determine any such scenarios where the network page repeat pattern is changing. In case where such pattern changes the validator algorithm tries to determine the updated page repeat pattern and hence in keeping the UE informed about the recent network page repeat pattern.
