Differentiated Paging via Service Attribute Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, the inability to differentiate service attributes in downlink data notification messages leads to a uniform paging policy, which deteriorates the quality of service provided to users and fails to prioritize important services.
Innovation Solution
Incorporating service attribute information, such as APN, EBI, QCI, LBI, IP address, protocol type, and DSCP/TOS, into downlink data notification messages to enable differentiated paging policies based on the specific attributes of user equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the downlink data notification message includes only TEID without service attribute information, then the mobility management network element can locate the user equipment for paging, but the mobility management network element cannot differentiate service attributes and perform differentiated processing
Solution Approach 1:
The notification message is segmented to include separate fields for TEID and service attribute information. The service attribute information is further segmented into multiple parameters including APN, EBI, QCI, LBI, IP address, protocol type, and DSCP/TOS, allowing the mobility management network element to process different service types independently while maintaining the core paging functionality.
2Ease of operation
If uniform paging policy is used for all services, then the paging process is simple, but the quality of service provided to users deteriorates and important services cannot be prioritized
Solution Approach 1:
Different quality attributes are assigned to different service types through the service attribute information parameters. The mobility management network element uses these parameters to apply local quality adjustments to the paging process, such as prioritizing voice services over data services, thereby improving overall service reliability while maintaining operational clarity through structured parameter handling.
Data Source
AI summary
A paging processing method, a communication apparatus, and a communication system are disclosed. The paging processing method includes: receiving, by a mobility management network element, a downlink data notification message which includes service attribute information of a downlink data packet; obtaining the service attribute information; and initiating paging of the user equipment based on different policies according to the service attribute information.
