vBNG Gateway Access with SLA-Based UP Device Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing technologies, terminals randomly access user plane (UP) devices in a virtual broadband network gateway (vBNG) due to allocation based on current user sessions or load, preventing specialized service provision.
Innovation Solution
Determine a UP device based on the Service Level Agreement (SLA) level of the terminal, allowing terminals with different SLA levels to access specific UP devices for differentiated services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the CP device allocates a UP device to the terminal based on a current quantity of user sessions or current load of each UP device, then the system achieves load balancing and resource utilization optimization, but the terminal randomly accesses a UP device and cannot access a specified UP device, preventing specialized service provision
Solution Approach 1:
The patent applies local quality by associating different UP devices with different service types or quality levels. Instead of uniform random allocation, each UP device is assigned specific service characteristics (e.g., high-speed service, low-latency service, best-effort service), allowing terminals requiring specialized services to be directed to appropriate UP devices while maintaining overall load balancing
2Ease of operation
If the system allows random access to UP devices based on current load, then the allocation process is simple and fast, but differentiated services cannot be provided to meet specific user requirements
Solution Approach 1:
The patent implements preliminary action by pre-configuring UP devices with specific service types or quality levels before terminal access. The CP device maintains an association between UP devices and service characteristics, enabling rapid lookup and allocation of appropriate UP devices to terminals based on their service requirements, thus maintaining simplicity while enabling differentiation

AI summary
This application discloses a method and an apparatus for accessing a gateway, and pertains to the field of communications technologies. In this application, an SLA level may be obtained based on user information of a terminal, and further a UP device corresponding to the terminal is determined based on the SLA level of the terminal. In this way, terminals with different SLA levels may be allocated to different UP devices for bearing, so that a specific terminal may access a specified UP device. This resolves a problem in a related technology that a terminal relatively randomly accesses a UP device. In addition, because an SLA level may be used to indicate a level of quality of service of a terminal, after terminals with different SLA levels access different UP devices, differentiated services may be provided on the different UP devices. Therefore, user requirements are met, and revenues are increased.
