Base Station Historical Camping Data for Targeted Paging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the current paging packet mechanism in radio access networks often results in false alarms and excessive power consumption due to all user equipment being alerted during a paging occasion, even if no paging packet is performed, especially affecting user equipment with low paging probabilities.
Innovation Solution
The method involves a base station transmitting historical camping information of inactive user equipment to a core network device, which allows for precise paging by determining the last camped cells and base stations, reducing unnecessary alerts and power consumption by using this information to determine accurate paging assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a paging packet mechanism is implemented in the radio access network to reduce false alarms, then the reliability of paging is improved, but all user equipment in a paging occasion is still alarmed when no paging packet is performed, causing excessive power consumption and false alarms
Solution Approach 1:
The base station performs preliminary actions by determining whether a paging packet is actually performed before triggering paging alerts. Historical camping information is retrieved in advance, and the paging packet status is determined beforehand, so that only necessary user equipment is alerted, avoiding unnecessary power consumption from false alarms.
Solution Approach 2:
Instead of paging all user equipment in a paging occasion, the invention applies partial action by selectively paging only those user equipment that are actually affected by the paging packet status. This is achieved by determining the paging packet status and using historical camping information to identify the specific subset of user equipment that needs to be paged, rather than broadcasting to all.
2Area of stationary object
If all user equipment is alerted during a paging occasion regardless of paging packet status, then the coverage of paging is improved, but false alarms increase and power consumption becomes excessive
Solution Approach 1:
The invention applies local quality by differentiating the paging behavior for different user equipment based on their historical camping information and the determined paging packet status. Instead of uniform paging for all user equipment, the system tailors the paging action locally to each user equipment's actual need, thereby maintaining necessary coverage while eliminating false alarms for those not affected.
Solution Approach 2:
The invention uses partial action by paging only the necessary subset of user equipment rather than all user equipment in the paging occasion. By determining the paging packet status and using historical camping information to identify affected user equipment, the system achieves adequate paging coverage for those who need it while avoiding false alarms for others.
3Measurement precision
If historical camping information is transmitted to enable precise paging, then the accuracy of paging is improved, but the complexity of the system increases
Solution Approach 1:
The base station performs preliminary actions by retrieving and storing historical camping information in advance, before the paging operation is needed. This preliminary preparation allows the system to quickly determine the paging packet status and identify the correct user equipment for paging without adding complexity during the actual paging execution, as the heavy lifting of information gathering is done beforehand.
