Description

Method for providing message service in5G system, MSGIN G server and non-MSGIN 5G gateway Technical Field The present disclosure relates to a wireless network, and more particularly, to a method, MSGin G server, and non-MSGin G gateway for providing message services in a 5G system Background In order to meet the demand for increased wireless data services since the deployment of fourth generation (4G) communication systems, efforts have been made to develop improved fifth generation (5G) or former 5G communication systems. Therefore, the 5G or front 5G communication system is also referred to as a "post 4G network" or a "post LTE system". A 5G communication system is considered to be implemented in a higher frequency (mmWave) band, for example, a 60GHz band, in order to achieve a higher data rate. In order to reduce propagation loss of radio waves and increase transmission distance, in 5G communication systems, beam forming, massive Multiple Input Multiple Output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beam forming, massive antenna techniques are discussed. Further, in the 5G communication system, development of system network improvement based on advanced small cell, cloud Radio Access Network (RAN), ultra dense network, device-to-device (D2D) communication, wireless backhaul, mobile network, cooperative communication, coordinated multipoint (CoMP), reception-side interference cancellation, and the like is underway. In5G systems, hybrid FSK and QAM modulation (FQAM) and Sliding Window Superposition Coding (SWSC) have been developed as Advanced Coding Modulation (ACM), filter Bank Multicarrier (FBMC), non-orthogonal multiple access (NOMA) and Sparse Code Multiple Access (SCMA) as advanced access techniques. In general, the third generation partnership project (3 GPP) is currently describing messages in the fifth generation (MSGin G) application service as a message service in a 5G system. The application architecture specified in 3gpp TS 23.554 for MSGin G application services is intended to support various User Equipment (UE) types based on the underlying transport services supported by the UE (e.g., MSGin G transport services, non MSGin G transport services). UE types include MSGin G UEs, legacy 3GPP UEs and non-3 GPP UEs. MSGin5G UEs support MSGin5G clients and are able to send MSGin5G message payloads. However, the legacy 3GPP UE does not support MSGin G, but uses one of the 3 GPP-defined messaging mechanisms (e.g., short Message Service (SMS), non-IP data delivery (NIDD), broadcast, etc.). Further, the non-3 GPP UE does not support MSGin G clients, but supports one of the non-3 GPP messaging mechanisms (e.g., rich Communication Services (RCS) and lightweight M2M (LwM 2M), etc.). It is therefore desirable to provide a useful alternative for delivering messages/MSGin G message payloads in5G systems. Disclosure of Invention Technical problem The primary purpose of embodiments herein is to use the Target Resolution Function (TRF) of a MSGin G server to determine whether a target UE supports MSGin G transport services upon receiving a MSGin G message request from a source UE to deliver a message to the target UE in a wireless network. Further, in response to determining that the target UE supports MSGin G transport services, the MSGin5G server sends a message to the target UE. Further, in response to determining that the target UE does not support MSGin G transport services, the MSGin G server selects a non-MSGin G gateway in the wireless network using a gateway selection function (GWSF) of the MSGin G server. In addition, the MSGin G server sends a message to the non-MSGin 5G gateway, where the non-MSGin 5G gateway translates the MSGin5G message request according to the non-MSGin 5G transport service using a Translation Function (TF) of the non-MSGin 5G gateway, and the non-MSGin 5G gateway sends the message to the target UE after translation. As a result, the source UE (i.e., MSGin5G UE) sends a message to the target UE (e.g., MSGin5G UE, legacy 3GPP UE, non-3 GPP UE, etc.) even though the target UE does not support MSGin G message payload/MSGin 5G client, and the target UE does not need any external hardware to communicate with the source UE. It is another object of embodiments herein to determine whether a target UE is registered in a MSGin G UE registration repository of a MSGin G server. Further, in response to determining that the target UE is registered in the MSGin G UE registration repository of the MSGin G server, the MSGin G server detects that the target UE supports MSGin G transport services. Further, in response to determining that the target UE is not registered in the MSGin G UE registration repository of the MSGin G server, the MSGin G server detects that the target UE supports non-MSGin G transport services. It is another object of embodiments herein to detect that a target UE is one of a legacy 3GPP UE and a non-3 GPP UE based on a Home Subscriber Server (HSS) and
