UE Session Reuse Decision Logic for Wireless Network Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In network slicing technologies, the existing methods for user equipment (UE) to determine whether to reuse or create a new session lead to increased signaling exchange between UE and the network side, resulting in network load inefficiencies.
Innovation Solution
The UE determines before initiating a create session request whether to reuse an existing session or create a new one, thereby reducing unnecessary session creation for services that can utilize existing sessions, thereby minimizing signaling exchange and alleviating network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the network side determines whether to reuse a created session or create a new session after receiving a session request, then session creation can be performed, but signaling exchange between the UE and the network side is increased
Solution Approach 1:
The patent inverts the decision-making process by having the UE determine whether to reuse an existing session or create a new session before sending the session request to the network side. This reversal of the decision authority from network side to UE side reduces signaling exchange because the UE can make the determination locally using stored session information, eliminating the need for the network side to process and respond to session creation requests for sessions that can be reused.
2Ease of operation
If the UE initiates a create session process for each new application service, then session management can be performed, but network load is increased
Solution Approach 1:
The patent applies preliminary action by having the UE store session information (including session ID, DNN, slice information, and service type) after initial session creation, and use this stored information to determine whether to reuse the session before initiating any create session process. This preliminary preparation of session information allows the UE to avoid unnecessary session creation for services that can utilize existing sessions, thereby reducing network load while maintaining ease of session management.

AI summary
This application relates to the field of wireless communications technologies, and provides a session processing method. The method discloses: obtaining, by user equipment UE, session type information, where the session type information is used to indicate a type of a first session; and when a first application triggers a first service, determining, by the UE based on the session type information, whether a create session request needs to be initiated for the first service. According to the solutions provided in embodiments, before the create session request is initiated, the UE may determine whether to reuse a created session or create a new session. In this way, for a service that can reuse a created session, no new session needs to be created, thereby reducing signaling exchange between the UE and a network side.
