Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile network communication services face challenges in meeting low-latency requirements due to the need for server-mediated communication between clients, which increases latency and affects user experience and communication efficiency.
Innovation Solution
A method and apparatus for session establishment that allows terminal devices in the same group to directly communicate through a shared forwarding device, bypassing the server, by determining and using a target forwarding device capable of supporting group communication services, thereby reducing latency and improving communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If server-mediated communication is used for mobile network services, then communication coverage and connectivity are improved, but transmission latency increases
Solution Approach 1:
The patent segments the communication path by introducing a forwarding device that operates independently from the traditional server-mediated architecture. The forwarding device establishes direct communication channels between terminal devices within the same group, separating the forwarding function from the server and enabling parallel communication paths that reduce latency while maintaining connectivity.
Solution Approach 2:
The patent introduces a forwarding device as an intermediary that facilitates direct communication between terminal devices. This forwarding device acts as a mediator that manages session establishment and packet forwarding without requiring server intervention, thereby reducing the communication path length and associated latency while ensuring reliable data transmission.
2Device complexity
If conventional server-based architecture is used, then system simplicity is maintained, but communication efficiency and user experience deteriorate
Solution Approach 1:
The patent merges the forwarding function with the communication efficiency requirements by integrating session management and packet forwarding capabilities into a unified forwarding device. This consolidation eliminates the need for separate server-based processing, achieving both architectural simplicity and enhanced communication efficiency through a single integrated component.
Solution Approach 2:
The forwarding device is designed with multi-functionality, handling session establishment, packet forwarding, and latency optimization within a single device. This universal approach replaces the traditional server-based architecture while maintaining system simplicity and improving communication efficiency through consolidated functionality.
3Loss of time
If direct communication between terminal devices is enabled, then transmission latency is reduced, but session management complexity increases
Solution Approach 1:
The patent applies preliminary action by establishing sessions in advance before actual data transmission occurs. The forwarding device pre-configures communication paths and manages session parameters before terminal devices need to communicate, thereby reducing latency during actual data transfer while simplifying session management through proactive configuration rather than reactive management.
Solution Approach 2:
The forwarding device implements self-service capabilities for session management, autonomously establishing and managing communication sessions between terminal devices without requiring complex external control mechanisms. This self-service approach reduces session management complexity while enabling direct communication and latency reduction through automated session handling.

AI summary
This application provides a session establishment method and apparatus, and a packet sending method and apparatus. The session establishment method includes: receiving, by a control device, first request information, where the first request information is used to indicate that a first terminal device requests to access a group communication service; determining a first terminal device group to which the first terminal device belongs; determining a target forwarding device that serves the first terminal device group, where the target forwarding device is a forwarding device capable of supporting a group communication service; and controlling the first terminal device to establish a session with the target forwarding device, to enable terminal devices in a same group to establish sessions with a same forwarding device, so that group service access between the terminal devices in the group can be completed by using the same forwarding device. Because data exchange of a group communication service does not need forwarding by a server, a transmission latency of the service can be reduced, to improve user experience, improve communication efficiency, and meet a low-latency requirement of a user for a communication service.
