Abstract

A method of selecting access network for routing data of user equipment (UE) is provided. The method includes receiving trigger indicating a requirement of one or more network services. Further, the method includes determining that a UE is registered on a Third Generation Partnership Project (3GPP) access network and a non-3GPP access network simultaneously. The method includes identifying availability of one or more network services in the 3GPP access network and the non-3GPP access network. Thereafter, the method includes selecting one of, the 3GPP access network and the non-3GPP network, based on availability of one or more network services in one of, the 3GPP access network and the non-3GPP access network, or selecting one of, the 3GPP access network and the non-3GPP network based on one or more network parameters, when one or more network services are available in the 3GPP access network and the non-3GPP access network.

First claim

What is claimed is:

1 . A method of selecting an access network for routing data of a User Equipment (UE) in a wireless communication network, the method comprising:
receiving, by a UE, a trigger indicating a requirement of one or more network services; determining, by the UE, that the UE is registered on a Third Generation Partnership Project (3GPP) access network and a non-3GPP access network simultaneously; identifying, by the UE, an availability of the one or more network services in the 3GPP access network and the non-3GPP access network, the identifying of the availability of the one or more network services including evaluating UE Route Selection Policy (URSP) rules of a first Public Land Mobile Network (PLMN) associated with the 3GPP access network and a second PLMN associated with the non-3GPP access network; and performing, by the UE, one of:
selecting one of, the 3GPP access network or the non-3GPP access network for routing data of the UE, based on the availability of the one or more network services in one of, the 3GPP access network or the non-3GPP access network, or
selecting one of, the 3GPP access network or the non-3GPP access network for routing data of the UE based on one or more network parameters, in response to the one or more network services being available in the 3GPP access network and the non-3GPP access network.

2 . The method of claim 1 , wherein the one or more network services comprise at least one of, voice services, video services, network slicing services for user applications, network slicing services for services of user applications, or Local Area Data Network (LADN) services.

3 . The method of claim 1 , wherein identifying the availability of the one or more network services in the 3GPP access network and the non-3GPP access network comprises:
determining the availability of the one or more network services in the 3GPP access network and the non-3GPP access network based on the evaluation.

4 . The method of claim 1 , wherein the one or more network parameters comprises at least one of, Round-Trip Time (RTT) delay or available bandwidth, in the 3GPP access network and the non-3GPP access network.

5 . The method of claim 1 , wherein the selection based on the one or more network parameters comprises:
measuring the one or more network parameters of the 3GPP access network and the non-3GPP access network; comparing the one or more network parameters of the 3GPP access network with the one or more network parameters of the non-3GPP access network; and selecting one of, the 3GPP access network or the non-3GPP access network, based on the comparison.

6 . The method of claim 1 , wherein the performing further comprises selecting one of, the 3GPP access network or the non-3GPP access network for routing data of the UE based on the one or more network parameters, in response to the one or more network services being unavailable in the 3GPP access network and the non-3GPP access network.

7 . A User Equipment (UE) for selecting an access network for routing data of the UE in a wireless communication network, the UE comprising:
a communication interface; one or more processors; and a memory storing processor-executable instructions, which, on execution, cause the one or more processors to:
receive a trigger indicating a requirement of one or more network services,
determine that the UE is registered on a Third Generation Partnership Project (3GPP) access network and a non-3GPP access network simultaneously,
identify an availability of the one or more network services in the 3GPP access network and the non-3GPP access network, the identifying of the availability of the one or more network services including evaluating UE Route Selection Policy (URSP) rules of a first Public Land Mobile Network (PLMN) associated with the 3GPP access network and a second PLMN associated with the non-3GPP access network, and
perform one of:
selecting one of, the 3GPP access network or the non-3GPP access network for routing data of the UE, based on the availability of the one or more network services, in one of, the 3GPP access network or the non-3GPP access network, or
selecting one of, the 3GPP access network or the non-3GPP access network for routing data of the UE based on one or more network parameters, in response to the one or more network services being available in the 3GPP access network and the non-3GPP access network.

8 . The UE of claim 7 , wherein the one or more network services comprise at least one of, voice services, video services, network slicing services for user applications, network slicing services for services of user applications, or Local Area Data Network (LADN) services.

9 . The UE of claim 7 , wherein the one or more processors identify the availability of the one or more network services in the 3GPP access network and the non-3GPP access network by:
determining the availability of the one or more network services in the 3GPP access network and the non-3GPP access network based on the evaluation.

10 . The UE of claim 7 , wherein the one or more network parameters comprises at least one of, Round-Trip Time (RTT) delay or available bandwidth, in the 3GPP access network and the non-3GPP access network.

11 . The UE of claim 7 , wherein the one or more processors perform the selection based on the one or more network parameters by:
measuring the one or more network parameters of the 3GPP access network and the non-3GPP access network; comparing the one or more network parameters of the 3GPP access network with the one or more network parameters of the non-3GPP access network; and selecting one of, the 3GPP access network or the non-3GPP access network, based on the comparison.

12 . The UE of claim 7 , wherein the one or more processors are further configured to select one of, the 3GPP access network or the non-3GPP access network for routing data of the UE based on the one or more network parameters, in response to the one or more network services being unavailable in the 3GPP access network and the non-3GPP access network.

13 . The UE of claim 7 , wherein the one or more network services comprise network slicing services for a plurality of services of a user application.

14 . The UE of claim 13 ,
wherein a first service of the plurality of services is routed on an application slice of the first PLMN associated with the 3GPP access network, and wherein a second service of the plurality of services is routed on an application slice of the second PLMN associated with the non-3GPP access network.

15 . The UE of claim 14 , wherein the first service of the plurality of services of the user application is routed on the application slice of the first PLMN associated with the 3GPP access network while the second service of the plurality of services of the user application is simultaneously routed on the application slice of the second PLMN associated with the non-3GPP access network.
