MBSSID Group Management for Dynamic VAP Slot Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The implementation of Multiple Basic Service Set Identifier (MBSSID) groups in wireless networks leads to inefficiencies such as beacon size bloating and underutilization of VAP slots due to fixed VAP capacity limitations, resulting in unavailable slots for new VAP creations and network outages when transmitted VAPs become inoperative.
Innovation Solution
Configuring MBSSID groups with a Maximum BSSID indicator that allows each group to utilize VAP slots up to the AP's capacity, enabling dynamic VAP creation and intelligent steering of non-transmitted VAPs to maintain network connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multiple MBSSID groups are formed to avoid beacon size bloating, then beacon size is reduced, but the number of VAP slots in each MBSSID group is limited
Solution Approach 1:
The patent implements dynamic VAP slot allocation where the maximum number of VAP slots per MBSSID group is no longer fixed but can be adjusted based on the Maximum BSSID indicator parameter. This allows the system to adapt the VAP capacity of each MBSSID group dynamically, resolving the contradiction between maintaining small beacon sizes and providing sufficient VAP slot availability.
2Stability of the object's composition
If fixed VAP capacity is allocated to each MBSSID group, then network stability is maintained, but VAP slots become unavailable for new VAP creations
Solution Approach 1:
The patent changes the parameter governing VAP slot capacity from a fixed value to one controlled by the Maximum BSSID indicator. This parameter change enables the system to maintain stability through controlled allocation while improving productivity by allowing new VAP creations when slots are available, as the allocation can be adjusted without disrupting existing MBSSID group structures.
3Reliability
If transmitted VAP becomes inoperative in an MBSSID group, then network outage occurs, but with intelligent steering capability
Solution Approach 1:
The patent implements feedback mechanisms through intelligent VAP steering that monitor the operational status of transmitted VAPs. When a transmitted VAP becomes inoperative, the system detects this condition and automatically steers non-transmitted VAPs to alternative MBSSID groups, providing feedback-driven fault tolerance that maintains network connectivity while managing complexity through automated responses.

AI summary
Examples described herein relate to a method for creating and managing a plurality of Multiple Basic Service Set Identifier (MBSSID) groups. The method may include configuring the MBSSID groups by setting a Maximum BSSID indicator to a value such that each of the plurality of MBSSID groups is allowed to utilize VAP slots up to a VAP capacity of the AP so long as the VAP capacity of the AP is not fully exhausted. Accordingly, when a request to create a VAP in a given MBSSID group is received, and the VAP capacity of the AP is not fully exhausted, the AP may create the VAP at any available VAP slot. The VAP is created such that a BSSID of the VAP is determined based on the Maximum BSSID indicator and a BSSID index relative to a transmit VAP of the given MBSSID group.
