Solution Overview

Problem

In the context of multiple access in EPS systems, user equipment (UE) experiences incorrect operations and unnecessary signal interactions due to its inability to determine whether the home agent (HA) supports multi-registration flow binding capacity, leading to inefficiencies in network resource management.

Innovation Solution

The method involves the HA sending first indication information to the UE upon establishing an MIPv6 security association, indicating its support for multi-registration flow binding, allowing the UE to determine whether to initiate such binding accordingly, thereby preventing incorrect operations and reducing signal interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the UE initiates multi-registration flow binding without knowing HA support, then the UE can potentially access multiple networks, but incorrect operations and unnecessary signal interactions occur

Engineering Contradiction:
Improvemulti-network access capabilityVSAvoidoperation correctness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The HA sends first indication information to the UE during the security association establishment phase, before the UE initiates multi-registration flow binding. This preliminary notification allows the UE to know whether the HA supports multi-registration flow binding in advance, preventing incorrect operations and unnecessary signal interactions.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the UE always attempts multi-registration flow binding, then multi-network access is enabled, but unnecessary signal interactions increase

Engineering Contradiction:
Improvemulti-network access capabilityVSAvoidsignal interaction time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The HA sends first indication information to the UE during the security association establishment phase, before the UE initiates multi-registration flow binding. This preliminary notification allows the UE to know whether the HA supports multi-registration flow binding in advance, preventing incorrect operations and unnecessary signal interactions.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If the HA does not provide capability indication, then the system maintains simplicity, but the UE cannot determine HA support for multi-registration flow binding

Engineering Contradiction:
Improvesystem complexityVSAvoidcapability information
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The first indication information acts as an intermediary carrier that transmits the HA's multi-registration flow binding capability from the HA to the UE. This simple information element enables the UE to make informed decisions about initiating multi-registration flow binding without adding significant system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If the UE checks HA capability before initiating binding, then operation correctness improves, but additional signaling is required

Engineering Contradiction:
Improveoperation correctnessVSAvoidsignaling complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The capability indication is merged into the existing security association establishment signaling between the UE and HA. By sending the first indication information during this existing procedure, the patent avoids adding separate capability check signaling, thus improving operation correctness without significantly increasing signaling complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A method for processing multiple access, a home agent and user equipment are disclosed in the present invention. The method includes the following steps: when a user equipment establishes a mobile internet protocol version 6 (MIPV6) security association with a home agent, the home agent sends first indication information to the user equipment, wherein the first indication information is used to indicate to the user equipment that the home agent is able to support multi-registration flow binding. The present invention can improve the system efficiency.
