Operator-Encrypted Partial URSP Delivery for 5G Network Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3GPP 5G system architectures face challenges in managing network communications and connectivity for wireless mobile network devices due to the complexity of networking architectures and the introduction of new mobile network paradigms, leading to a poor quality of experience (QOE) when applications without configured URSP rules are operated.
Innovation Solution
The method involves obtaining an application-specific user equipment route selection policy (URSP) object from a policy function of a mobile network, which is encrypted by the policy function, and providing it to a user equipment (UE) for decryption and integration with the existing URSP, allowing for enhanced network communications tailored to specific applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If application-specific URSP rules are configured for each application, then the quality of experience for UE users is improved, but the signaling load on the mobile network increases
Solution Approach 1:
The URSP policy is segmented into application-specific rules that are delivered individually to the UE. Each application receives only its relevant URSP rules rather than the complete policy set, reducing the signaling load while maintaining quality of experience through targeted policy delivery.
Solution Approach 2:
The patent delivers partial URSP rules specific to each application rather than the complete URSP policy. This partial action approach reduces the amount of signaling required while still providing the necessary routing guidance for each application to achieve good quality of experience.
2Adaptability or versatility
If complete URSP policies are provided to all UEs, then all applications can be properly routed, but the size of operator-provided URSPs increases
Solution Approach 1:
The complete URSP policy is segmented into application-specific subsets. Each UE receives only the URSP rules relevant to its installed applications, reducing the overall size of operator-provided URSPs while maintaining full routing capability for each application through targeted rule delivery.
Solution Approach 2:
Each UE receives URSP rules with local quality tailored to its specific application portfolio. The operator provides different URSP rule sets to different UEs based on their application requirements, optimizing the balance between routing capability and message size for each individual UE.
3Ease of manufacture
If URSP rules are delivered through traditional registration processes, then policy delivery is simplified, but the complexity of managing network communications increases
Solution Approach 1:
The traditional monolithic URSP delivery process is segmented into application-specific rule deliveries. This segmentation simplifies the overall policy delivery process by breaking it into manageable application-specific transactions while reducing network management complexity through automated rule generation and targeted delivery mechanisms.

AI summary
Presented herein are techniques to provide an operator-encrypted application specific user equipment (UE) route selection policy (URSP) to a UE via different network elements and/or distribution techniques. In one example, a method may include obtaining, by a network element, a policy object from a policy function of a mobile network operated by a mobile network operator, wherein the policy object comprises an application specific user equipment route selection policy (URSP) for an application in which the application specific URSP is encrypted by the policy function; and providing, by the network element, the policy object to a user equipment that has at least one session established with the mobile network, wherein the user equipment is to decrypt the application specific URSP to facilitate network communications for the application via the user equipment.
