Solution Overview

Problem

Current technologies face challenges in realizing seamless information forwarding between fixed and mobile networks, particularly in ensuring Quality of Service (QoS) parameters are maintained during data transmission across different network sessions, leading to instability in data transmission.

Innovation Solution

An information processing method and apparatus that involves an access gateway receiving a message with a data packet, QoS parameter, and fixed network session ID, mapping the fixed network session to a mobile network session using pre-stored information, and forwarding the data packet to a User Plane Function (UPF), ensuring QoS parameter consistency across network functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed network session information is directly forwarded to mobile network core, then information forwarding between networks is achieved, but QoS parameter consistency cannot be maintained

Engineering Contradiction:
Improvenetwork convergence capabilityVSAvoidQoS parameter consistency
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The access gateway acts as an intermediary between the fixed network access device and the mobile network core. It receives fixed network session information including QoS parameters, performs mapping transformation to mobile network session format, and forwards to the UPF. This intermediary role enables network convergence while maintaining QoS parameter consistency through structured transformation.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The access gateway changes the parameter representation format of QoS parameters when transforming fixed network session information to mobile network session information. It maps fixed network QoS parameters to corresponding mobile network QoS parameters, ensuring parameter consistency across different network types while enabling seamless forwarding.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If complete decoupling of access networks and core networks is implemented, then network convergence is achieved, but data transmission stability deteriorates

Engineering Contradiction:
Improvenetwork convergenceVSAvoiddata transmission stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The access gateway performs preliminary mapping transformation of fixed network session information to mobile network session format before forwarding to the core network. This preliminary action ensures that the decoupled architecture can maintain stable data transmission by pre-aligning the information format with the mobile network's expectations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The access gateway serves as a stable intermediary that bridges the decoupled fixed and mobile networks. It maintains protocol compatibility and QoS parameter consistency across the interface, thereby stabilizing data transmission while enabling complete network decoupling and convergence.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If QoS control is performed according to VLAN priority, then QoS control functionality is achieved, but information forwarding complexity increases

Engineering Contradiction:

Solution Approach 1:

The access gateway acts as an intermediary that handles QoS parameter transformation between fixed and mobile networks. It maps fixed network QoS parameters (including VLAN priority) to mobile network QoS parameters, enabling QoS control functionality while managing the complexity through structured transformation logic.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The access gateway changes QoS parameter representations during the forwarding process. It transforms fixed network QoS parameters to mobile network QoS parameters, maintaining QoS control capability while simplifying the overall forwarding process through automated parameter mapping.

Inventive Principle:
Principle #35Parameter changes

AI summary

An information processing method and apparatus, and a computer-readable storage medium. The information processing method comprises: an access gateway receives a first message that is borne in a fixed network session (S 100), and maps the fixed network session and a mobile network session according to the first message and pre-stored mapping information, thus a data packet in the first message can be sent to a user plane function (S200).
