Selective Base Station Paging for Dormant Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, paging a mobile device when it is not in communication with the network results in inefficient use of network resources due to multiple fruitless attempts across multiple cell towers, as the network does not always know the device's location.
Innovation Solution
A mobility management function determines sets of network base stations to page the user device by filtering a base station history using selection criteria, including the most recent base stations in communication, time of communication, and tracking area, optimizing the paging process to improve the likelihood of successful contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network sends multiple pages through multiple cell towers to page a dormant user device, then the likelihood of successfully contacting the device is improved, but network resources are wasted due to many fruitless paging attempts
Solution Approach 1:
The system performs preliminary actions by maintaining a base station history database that records which base stations have previously communicated with each user device. Before paging a dormant device, the system queries this history to identify the most relevant base stations, thereby preparing in advance the optimal paging targets and avoiding fruitless attempts at other base stations.
Solution Approach 2:
The system uses feedback from historical paging responses and communication patterns to continuously refine the base station history. By analyzing which base stations successfully contacted devices in the past and which attempts were fruitless, the system learns and adjusts its paging strategy, improving future paging efficiency while reducing wasted network resources.
2Reliability
If the network pages all possible base stations for a dormant device, then no base station is missed, but the complexity of the paging system increases
Solution Approach 1:
The system segments the paging process into distinct phases: first querying the base station history database for relevant base stations, then paging only those specific base stations identified from historical data. This segmentation allows the system to maintain completeness for the relevant subset of base stations without the complexity of managing all possible base stations.
Solution Approach 2:
The system performs preliminary querying of the base station history database before executing the paging operation. This preliminary action identifies the specific subset of base stations that need to be paged, reducing the complexity of the main paging execution while ensuring all relevant base stations are covered.
3Measurement precision
If the network maintains detailed base station history for all user devices, then paging accuracy is improved, but the storage and processing requirements increase
Solution Approach 1:
The system extracts only the essential information needed for paging decisions from the base station history - specifically, which base stations have previously communicated with each user device. By extracting and storing only this critical data rather than maintaining complete communication records, the system achieves high paging accuracy with reduced storage requirements.
Solution Approach 2:
The system performs preliminary filtering and consolidation of base station history data, keeping only the most relevant entries for paging purposes. This preliminary processing reduces the quantity of stored data while maintaining the precision needed for accurate paging decisions.

AI summary
Technology, including systems, methods, and devices, is disclosed herein to page a user device for communication with a wireless network. In an implementation, a mobility management function of the wireless network receives a request to page a user device. The mobility management function determines a set of network base stations to page the user device and sends, via the set of network base stations, a page to the user device. The set of network base stations is determined by filtering a base station history associated with the user device according to a filtering rule which includes the base station most recently in communication with the device. In some implementations, a set of base stations to page the user device is determined by filtering the base station history according to the time of the request during the trailing week.
