Method and system for dual role handling in a wireless environment

Abstract

The various embodiments herein provide a method and system for dual role handling between at least two devices in a wireless environment. The method comprises seeking, by a first device, at least one device with a specified connection topology, establishing a connection with a second device having a same connection topology, establishing an Application service platform (ASP) session with the second device once the connection is established between the first device and the second device, sending, by the first device, a role negotiation message comprising a request for role change to the second device, wherein the role negotiation message corresponds to a WSB message, receiving a custom message for confirmation, if the second device accepts the role change, and changing the connection topology between the first device and the second device once the role negotiation between the first device and the second device is completed.

Description

technical field [0001] Embodiments herein relate generally to wireless communication systems, and more specifically, to a method and system for dual role handling during USB connections set up in a wireless environment. Background technique [0002] Wireless Serial Bus is the Protocol Abstraction Layer (PAL) entity for running USB over Wi-Fi, and also handles the Wi-Fi-related aspects of creating a USB connection, like discovery of USB devices and management of connections that manage power. Media Agnostic USB (MA-USB) is an entity that defines support for all USB transfer types (block, interrupt, isochronous and control transfers and enumerations) for USB devices. This is medium agnostic and relies on a medium specific PAL, like Wireless Serial Bus (WSB), for the setup and handling of the underlying medium connectivity. Both WSB and MA-USB layers support client and host roles. Application Service Protocol (ASP) is a protocol that provides a framework for initiating and co...

Problems solved by technology

But when USB operates over a wireless connection, it assumes underlying Wi-Fi Direct connectivity

Wi-Fi Direct connections will be shared across all services, and multiple USB sessions can also be in progress, in which case it is likely that existing traditional service-based role definitions will not function properly

Users may see that some times the service is able to connect to other devices and some times it cannot because the role assumed during connection setup does not support

This will lead to bad user experience
