Base Station Paging Capability Detection from Paging Cause Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, terminal devices with multiple communication cards may fail to determine the paging capability of a base station when the base station does not send a paging cause, leading to failure in establishing services.
Innovation Solution
The terminal device acquires and analyzes a paging cause information element in the paging signaling to determine the paging capability of the base station, even if the base station does not send the cause, using methods such as identifying a preset identifier or system information to infer capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the base station does not send the paging cause information element, then the paging signaling structure is simpler, but the terminal device cannot determine the base station's paging capability
Solution Approach 1:
The patent introduces a preset identifier as an intermediary element within the paging cause information element. This identifier acts as a mediator that conveys the base station's paging capability indirectly when the base station chooses not to send the complete paging cause. The terminal device recognizes this preset identifier to understand that the base station is capable of sending paging cause but elects not to do so in this instance, thus resolving the information loss without increasing overall signaling complexity.
Solution Approach 2:
The patent changes the parameter state of the paging cause information element by introducing a specific preset identifier value that indicates the base station's capability. Instead of always transmitting the full paging cause, the system uses parameter variation (the presence of the preset identifier) to convey capability information, allowing the terminal device to adapt its behavior based on the detected parameter state.
2Loss of information
If the terminal device requests the paging cause from the base station, then the terminal device can obtain complete paging information, but the communication overhead increases
Solution Approach 1:
The patent applies preliminary action by having the base station pre-indicate its paging capability through the preset identifier in the paging cause information element. This advance indication allows the terminal device to determine whether to request paging cause information before initiating a request, avoiding unnecessary communication overhead. The base station performs the capability indication in advance, enabling the terminal to make informed decisions about subsequent actions.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal device can send a paging cause request to the base station if it determines that the paging cause is needed. The base station then responds with the requested information. This feedback loop ensures that paging cause information is transmitted only when necessary, balancing information completeness with communication efficiency.
3Loss of information
If the terminal device determines paging capability through system information, then the capability can be obtained, but the method is less direct and increases processing time
Solution Approach 1:
The patent uses preliminary action by having the base station pre-configure and broadcast system information that includes paging capability indications. This advance preparation allows the terminal device to quickly determine paging capability without real-time negotiation or complex processing. The capability information is prepared in advance and made readily available to terminals.
Solution Approach 2:
The patent employs copying by including paging capability information in system information broadcasts. Instead of requiring direct real-time queries or complex interactions, the base station creates a copy of its capability information and distributes it through standard system information channels, allowing terminal devices to obtain the information efficiently without direct time-consuming exchanges.

AI summary
The present disclosure provides a method, a communication device and a non-transitory computer storage medium for distinguishing paging capability of a base station, and a communication device, belonging to the technical field of wireless communication. The method includes: a terminal device receives paging signaling of a base station, and acquires a paging cause information element in the paging signaling, where the paging cause information element is used to carry a paging cause. In such a way, even if the base station does not send the paging cause to the terminal device, the terminal device can still determine the paging capability of the base station according to the paging cause information element, so as to perform subsequent actions or corresponding determinations according to the paging capability of the base station.
