Abstract

Embodiments herein provide a method for managing Quality of Service (QoS) of applications in a wireless network. Detecting a plurality of data traffic of plurality of applications based on current activities of a user equipment (UE), hardware components of UE, a plurality traffic parameter, a QoS report received from an access point (AP) associated with UE in a wireless network. Detecting an enhanced distributed channel access (EDCA) function based on plurality of data traffic. The EDCA function includes current mapping between access category of each data structure and traffic category of plurality of data traffic based on association. Classifying plurality of data traffic of the plurality of applications into priority data traffic category and non-priority data traffic category based on current mapping of the EDCA function. Modifying current mapping of EDCA function based on priority data traffic category, non-priority data traffic category, and access category of each data structure of plurality of data structures.

First claim

What is claimed is:

1 . A method for managing a quality of service (QoS) of applications in a wireless network, the method comprising:
detecting, by a user equipment (UE), a plurality of data traffic of a plurality of applications, wherein each data traffic of the plurality of data traffic has an association with at least one data structure of a plurality of data structures of the UE; detecting, by the UE, an enhanced distributed channel access (EDCA) function based on the plurality of data traffic, wherein the EDCA function comprises a mapping between an access category of each data structure and a traffic category of each data traffic of the plurality of data traffic based on the association; classifying, by the UE, the plurality of data traffic of the plurality of applications into a priority data traffic category and a non-priority data traffic category based on the mapping; and modifying, by the UE, the mapping based on the priority data traffic category, the non-priority data traffic category, and the access category.

2 . The method of claim 1 , wherein modifying, by the UE, the mapping based on the priority data traffic category, the non-priority data traffic category, and the access category comprises:
detecting, by the UE, at least one current data structure of the plurality of data structures associated with at least one data traffic of the plurality of data traffic classified into the priority data traffic category; detecting, by the UE, an access category of the at least one current data structure as one of a priority access category and a non-priority access category; and upgrading, by the UE, the mapping by translating the at least one data traffic classified into the priority data traffic category from the at least one current data structure to at least one another data structure of the plurality of data structures having the priority access category, based on the access category of the at least one current data structure indicating the non-priority access category.

3 . The method of claim 2 , wherein translating the data traffic comprises:
detecting, by the UE, an internet protocol (IP) header of each data traffic of the plurality of data traffic whether a differentiated services code point (DSCP) value is set to a default value; and allocating, by the UE, the DSCP value in the IP header based on the priority data traffic category and the non-priority data traffic category, based on the DSCP value not being set or being set to the default value.

4 . The method of claim 1 , wherein modifying, by the UE, the mapping based on the priority data traffic category, the non-priority data traffic category, and the access category comprises:
detecting, by the UE, at least one current data structure of the plurality of data structures associated with the at least one data traffic of the plurality of data traffic classified into the non-priority data traffic category; detecting, by the UE, an access category of the at least one current data structure as one of a priority access category and a non-priority access category; and downgrading, by the UE, the mapping by translating the at least one data traffic classified into the non-priority data traffic category from the at least one current data structure to the at least one another data structure of the plurality of data structures having the non-priority access category, based on the access category of the at least one current data structure indicating the priority access category.

5 . The method of claim 4 , wherein translating the data traffic comprises:
detecting, by the UE, an internet protocol (IP) header of each data traffic of the plurality of data traffic whether a differentiated services code point (DSCP) value is set to a default value; and allocating, by the UE, the DSCP value in the IP header based on the priority data traffic category and the non-priority data traffic category, based on the DSCP value not being set or being set to the default value.

6 . The method of claim 5 , wherein the method comprises:
monitoring, by the UE, a packet loss rate and an error packet for each data traffic of the plurality of data traffic based on an allocated DSCP value; determining, by the UE, a drop in the QoS for the data traffic classified into the priority data traffic category and the non-priority data traffic category based on the packet loss rate and the error packet; and modifying, by the UE, the allocated DSCP value for the data traffic classified into the priority data traffic category and the non-priority data traffic category back to the detected DSCP value in the IP header, based on the drop in the QoS being determined.

7 . The method of claim 1 , wherein detecting, by a UE, the plurality of data traffic of the plurality of applications is based on at least one of current activities of the UE, hardware components of the UE, a plurality traffic parameter, a QoS report received from at least one access point (AP) associated with the UE in the wireless network.

8 . A method for managing a quality of service (QoS) of applications in a wireless network, the method comprising:
receiving, by an access point (AP), a plurality of parameters from a plurality of devices available in the wireless network; generating, by the AP, a QoS report based on the plurality of parameters received from the plurality of devices, wherein the QoS report comprises at least one of a wireless network usage pattern by each device of the plurality of devices, a list of active devices from the plurality of devices, a list of inactive device from the plurality of devices, a metadata of data traffic associated with the list of active devices, and a metadata data traffic associated with a list of inactive devices; receiving, by the AP, a request message for the QoS report from a user equipment (UE) in the wireless network; and sending, by the AP, the QoS report to the UE for managing the QoS of the applications in the wireless network.

9 . A user equipment (UE) configured to manage a quality of service (QoS) of applications in a wireless network, the UE comprising:
a memory storing a plurality of applications; at least one processor; and a traffic translation controller communicatively coupled to the memory and the processor, wherein the traffic translation controller is configured to:
detect a plurality of data traffic of a plurality of applications based on at least one of current activities of the UE, hardware components of the UE, a plurality traffic parameters, a QoS report received from at least one AP associated with the UE in the wireless network, wherein each data traffic of the plurality of data traffic has an association with at least one data structure of a plurality of data structures of the UE,
detect an enhanced distributed channel access (EDCA) function based on the plurality of data traffic, wherein the EDCA function comprises a mapping between an access category of each data structure and a traffic category of each data traffic of the plurality of data traffic based on the association,
classify the plurality of data traffic of the plurality of applications into a priority data traffic category and a non-priority data traffic category based on the mapping, and
modify the mapping based on the priority data traffic category, the non-priority data traffic category, and the access category.

10 . The UE of claim 9 , wherein the traffic translation controller is further configured to:
detect at least one current data structure of the plurality of data structures associated with at least one data traffic of the plurality of data traffic classified into the priority data traffic category; detect an access category of the at lea
