Communication Apparatus Master Slave State Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies, particularly in Wi-Fi Direct mode, face challenges in enabling a target apparatus to participate in a wireless network efficiently, as they lack a systematic approach to determine and adapt to the master or slave station state of communication apparatuses, leading to difficulties in establishing appropriate connections.
Innovation Solution
A communication apparatus with a processor and memory that determines its current state as either a master station or slave station and accordingly performs specific communications to enable a target apparatus to join a wireless network, either by direct communication or by requesting connection through a master station apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the communication apparatus performs direct communication with the target apparatus to enable network participation, then the connection establishment speed is improved, but the system complexity increases due to the need to determine and adapt to master/slave station states
Solution Approach 1:
The communication apparatus dynamically adjusts its communication behavior based on its determined station state. When in master station state, it performs direct communication with the target apparatus for fast network participation. When in slave station state, it requests the master station apparatus to facilitate the connection. This dynamic adaptation resolves the contradiction by optimizing connection speed according to the current system configuration.
Solution Approach 2:
The apparatus changes its communication mode parameter based on the determined station state. In master station state, it uses direct communication mode; in slave station state, it uses indirect communication mode through the master station apparatus. This parameter change allows the system to maintain simplicity in each state while achieving fast connection establishment overall.
2Reliability
If the communication apparatus adapts its communication method based on master/slave station state, then the network participation reliability is improved, but the processing time increases due to state determination requirements
Solution Approach 1:
The communication apparatus performs state determination as a preliminary action before executing the communication protocol for network participation. By determining whether it is in master or slave station state in advance, the apparatus can select the appropriate communication method, ensuring reliable network participation while minimizing the time penalty to just the state determination step.
3Device complexity
If the communication apparatus uses indirect communication through the master station apparatus, then the device complexity is reduced, but the connection establishment speed decreases
Solution Approach 1:
The communication protocol is segmented into two paths: a direct communication path for master station state and an indirect communication path through the master station apparatus for slave station state. This segmentation allows each path to be optimized independently - the direct path for speed and the indirect path for simplicity - resolving the contradiction between connection speed and device complexity.

AI summary
A communication apparatus includes a processor to perform determining whether a current state of the communication apparatus is a master station state or a slave station state; controlling to perform, in a first case where it is determined that the current state of the communication apparatus is the master station state, a first type communication with the target apparatus to enable the target apparatus to participate in the specific wireless network, and controlling to transmit, in a second case where it is determined that the current state of the communication apparatus is the slave station state, transmits a communication request to perform a second type communication to enable the target apparatus to participate in the specific wireless network between the master station apparatus and the target apparatus.
