Virtual User-Specific Service Gateways for Mobile Network Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network architectures lack flexibility in adapting to user-specific mobility behavior and application-specific quality of experience (QoE)/quality of service (QoS) requirements, as they employ a one-size-fits-all approach for packet data network gateways and service gateways, which are not dynamically configurable to changing radio access network topologies.
Innovation Solution
The implementation of virtual user-specific service gateways (v-u-SGWs) that are created and configured based on user equipment (UE) registration, providing layer 3, layer 2, and layer 1 anchor point functionalities, and are dynamically relocatable and reconfigurable to meet UE-specific and network-specific requirements, allowing for customized data plane network topology and resource management.

Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed network SGW architecture is used, then network simplicity is maintained, but flexibility to adapt to user-specific mobility behavior and application-specific QoE/QoS requirements deteriorates
Solution Approach 1:
The patent segments the traditional monolithic SGW into multiple virtual user-specific service gateways (v-u-SGWs), where each v-u-SGW is dedicated to serving a specific UE. This segmentation enables user-specific customization and mobility behavior adaptation while maintaining the overall network architecture's simplicity through virtualization.
Solution Approach 2:
The patent introduces dynamic creation and destruction of v-u-SGWs based on UE registration and deregistration events. The v-u-SGW associated with a UE is created when the UE registers and destroyed when the UE deregisters, allowing the network to dynamically adapt to changing user requirements and mobility patterns.
2Adaptability or versatility
If a fixed network SGW is used, then network deployment simplicity is maintained, but ability to adapt to dynamic RAN topology changes deteriorates
Solution Approach 1:
The patent enables dynamic adaptation to RAN topology changes through the creation and relocation of v-u-SGWs. When RAN topology changes occur, the network can dynamically create new v-u-SGWs or relocate existing ones to appropriate locations, ensuring continuous service quality without requiring complex manual reconfiguration.
Solution Approach 2:
The system employs self-service mechanisms where the network automatically creates, configures, and manages v-u-SGWs based on UE registration information and network conditions. This automation reduces manual deployment complexity while enabling adaptive response to dynamic RAN topology changes.
3Adaptability or versatility
If a traditional SGW with limited functionality is used, then device complexity is reduced, but ability to provide customized packet processing deteriorates
Solution Approach 1:
The patent applies local quality by configuring each v-u-SGW with UE-specific packet processing functionalities tailored to the individual user's requirements. Different v-u-SGWs can have different packet processing capabilities based on the specific needs of their associated UEs, enabling customized service delivery.
Solution Approach 2:
The patent utilizes parameter changes by dynamically configuring v-u-SGWs with different operational parameters based on UE characteristics and service requirements. The gateway functionality can be adjusted by changing configuration parameters such as packet processing rules, QoS parameters, and mobility management settings.
